Interview with a candidate. He calls himself "C++ expert" on his resume. I think: "oh, great, I love C++ too, we will have an interesting conversation!"

Me: let's start with an easy one, what is 'nullptr'?
Him: (...some undecipherable sequence of words that didn't make any sense...)

In my mind: mh, probably I didn't understand right. Let's try again with something simple and more generic

Me: can you tell me about memory management in C++?
Him: you create objects on the stack with the 'new' keyword and they get automatically released when no other object references them

In my mind: wtf is this guy talking about? Is he confusing C++ with Java? Does he really know C++? Let's make him write some code, just to be sure

Me: can you write a program that prints numbers from 1 to 10?

Ten minutes and twenty mistakes later...

Me: okay, so what is this <int> here in angle brackets? What is a template?
Him: no idea

Me: you wrote 'cout', why sometimes do I see 'std::cout' instead? What is 'std'?
Answer: no idea, never heard of 'std'

I think: on his resume he also said he is a Java expert. Let's see if he knows the difference between the two. He *must* have noticed that one is byte-compiled and the other one is compiled to native code! Otherwise, how does he run his code? He must answer this question correctly:

Me: what is the difference between Java and C++? One has a Virtual Machine, what about the other?
Him: Java has the Java Virtual Machine
Me: yes, and C++?
Him: I guess C++ has a virtual machine too. The C++ Virtual Machine

Me (exhausted): okay, I don't have any other questions, we will let you know

And this is the story of how I got scared of interviews

Being paid to rewrite someone else's bad code is no joke.

I'll give the dev this, the use of gen 1,2,3 Pokemon for variable names and class names in beyond fantastic in terms of memory and childhood nostalgia. It would be even more fantastic if he spelt the names correctly, or used it to make a Pokemon game and NOT A FUCKING ACCOUNTANCY PROGRAM.

There's no correspondence in name according to type, or even number. Dev has just gone batshit, left zero comments, and now somehow Ryhorn is shitting out error codes because of errors existing in Charmeleon's asshole.

The things I do for money...

Toilets and race conditions!

A co-worker asked me what issues multi-threading and shared memory can have. So I explained him that stuff with the lock. He wasn't quite sure whether he got it.

Me: imagine you go to the toilet. You check whether there's enough toilet paper in the stall, and it is. BUT now someone else comes in, does business and uses up all paper. CPUs can do shit very fast, can't they? Yeah and now you're sitting on the bowl, and BAMM out of paper. This wouldn't have happened if you had locked the stall, right?

Him: yeah. And with a single thread?

Me: well if you're alone at home in your appartment, there's no reason to lock the door because there's nobody to interfere.

Him: ah, I see. And if I have two threads, but no shared memory, then it is as if my wife and me are at home with each a toilet of our own, then we don't need to lock either.

Me: exactly!

Account guy saw me coding...

account guy: so you type a lot.. how can you remember so much??

me: ??

account guy: I mean there is NO LOGIC in what you do, so you must read these things and type them here... you need to remember a lot.. right??

me: ohh... that... well.. I have very good memory :)

p.s. last line was sarcasm

Had a PR blocked yesterday. Oh god, have I introduced a memory leak? Have I not added unit tests? Is there a bug? What horrible thing have I unknowingly done?

... added comments to some code.

Yep apparently “our code needs to be readable without comments, please remove them”.

Time to move on, no signs of intelligent life here.

So I cracked prime factorization. For real.

I can factor a 1024 bit product in 11hours on an i3.
No GPU acceleration, no massive memory overhead. Probably a lot faster with parallel computation on a better cpu, or even on a gpu.

4096 bits in 97-98 hours.

Verifiable. Not shitting you. My hearts beating out of my fucking chest. Maybe it was an act of god, I don't know, but it works.

What should I do with it?

In a user-interface design meeting over a regulatory compliance implementation:
User: “We’ll need to input a city.”
Dev: “Should we validate that city against the state, zip code, and country?”
User: “You are going to make me enter all that data? Ugh…then make it a drop-down. I select the city and the state, zip code auto-fill. I don’t want to make a mistake typing any of that data in.”
Me: “I don’t think a drop-down of every city in the US is feasible.”
Manage: “Why? There cannot be that many. Drop-down is fine. What about the button? We have a few icons to choose from…”
Me: “Uh..yea…there are thousands of cities in the US. Way too much data to for anyone to realistically scroll through”
Dev: “They won’t have to scroll, I’ll filter the list when they start typing.”
Me: “That’s not really the issue and if they are typing the city anyway, just let them type it in.”
User: “What if I mistype Ch1cago? We could inadvertently be out of compliance. The system should never open the company up for federal lawsuits”
Me: “If we’re hiring individuals responsible for legal compliance who can’t spell Chicago, we should be sued by the federal government. We should validate the data the best we can, but it is ultimately your department’s responsibility for data accuracy.”
Manager: “Now now…it’s all our responsibility. What is wrong with a few thousand item drop-down?”
Me: “Um, memory, network bandwidth, database storage, who maintains this list of cities? A lot of time and resources could be saved by simply paying attention.”
Manager: “Memory? Well, memory is cheap. If the workstation needs more memory, we’ll add more”
Dev: “Creating a drop-down is easy and selecting thousands of rows from the database should be fast enough. If the selection is slow, I’ll put it in a thread.”
DBA: “Table won’t be that big and won’t take up much disk space. We’ll need to setup stored procedures, and data import jobs from somewhere to maintain the data. New cities, name changes, ect. ”
Manager: “And if the network starts becoming too slow, we’ll have the Networking dept. open up the valves.”
Me: “Am I the only one seeing all the moving parts we’re introducing just to keep someone from misspelling ‘Chicago’? I’ll admit I’m wrong or maybe I’m not looking at the problem correctly. The point of redesigning the compliance system is to make it simpler, not more complex.”
Manager: “I’m missing the point to why we’re still talking about this. Decision has been made. Drop-down of all cities in the US. Moving on to the button’s icon ..”
Me: “Where is the list of cities going to come from?”
<few seconds of silence>
Dev: “Post office I guess.”
Me: “You guess?…OK…Who is going to manage this list of cities? The manager responsible for regulations?”
User: “Thousands of cities? Oh no …no one is our area has time for that. The system should do it”
Me: “OK, the system. That falls on the DBA. Are you going to be responsible for keeping the data accurate? What is going to audit the cities to make sure the names are properly named and associated with the correct state?”
DBA: “Uh..I don’t know…um…I can set up a job to run every night”
Me: “A job to do what? Validate the data against what?”
Manager: “Do you have a point? No one said it would be easy and all of those details can be answered later.”
Me: “Almost done, and this should be easy. How many cities do we currently have to maintain compliance?”
User: “Maybe 4 or 5. Not many. Regulations are mostly on a state level.”
Me: “When was the last time we created a new city compliance?”
User: “Maybe, 8 years ago. It was before I started.”
Me: “So we’re creating all this complexity for data that, realistically, probably won’t ever change?”
User: “Oh crap, you’re right. What the hell was I thinking…Scratch the drop-down idea. I doubt we’re have a new city regulation anytime soon and how hard is it to type in a city?”
Manager: “OK, are we done wasting everyone’s time on this? No drop-down of cities...next …Let’s get back to the button’s icon …”

Simplicity 1, complexity 0.

Dear Technical Support,

Last year I upgraded from Boyfriend 5.0 to Husband 1.0 and noticed a distinct slow down in overall system performance — particularly in the flower and jewelry applications, which operated flawlessly under Boyfriend 5.0. The new program also began making unexpected changes to the accounting modules.

In addition, Husband 1.0 uninstalled many other valuable programs, such as Romance 9.5 and Personal Attention 6.5 and then installed undesirable programs such as NFL 5.0, NBA 3.0, and Golf Clubs 4.1.

Conversation 8.0 no longer runs, and Housecleaning 2.6 simply crashes the system. I’ve tried running Nagging 5.3 to fix these problems, but to no avail.

What can I do?

Signed,

Desperate

——————————————————–

Dear Desperate:

First keep in mind, Boyfriend 5.0 is an Entertainment Package, while Husband 1.0 is an Operating System.

Please enter the command: ” C:/ I THOUGHT YOU LOVED ME” and try to download Tears 6.2 and don’t forget to install the Guilt 3.0 update.

If that application works as designed, Husband 1.0 should then automatically run the applications Jewelry 2.0 and Flowers 3.5. But remember, overuse of the above application can cause Husband 1.0 to default to Grumpy Silence 2.5, Happy Hour 7.0 or Beer 6.1.

Beer 6.1 is a very bad program that will download the Snoring Loudly Beta.

Whatever you do, DO NOT install Mother-in-law 1.0 (it runs a virus in the background that will eventually seize control of all your system resources).

Also, do not attempt to reinstall the Boyfriend 5.0 program. These are unsupported applications and will crash Husband 1.0.

In summary, Husband 1.0 is a great program, but it does have limited memory and cannot learn new applications quickly.

You might consider buying additional software to improve memory and performance. We recommend Food 3.0 and Hot Lingerie 7.7.

Good Luck,
Tech Support

Apple has a real problem.

Their hardware has always been overpriced, but at least before it had defenders pointing out that it was at least capable and well made.

I know, I used to be one of them.

Past tense.

They have jumped the shark.

They now make pretentious hipster crap that is massively overpriced and doesn't have the basic features (like hardware ports) to enable you to do your job.

I mean, who needs an ESC key? What is wrong with learning to type CTRL-[ instead? Muscle memory? What's that?

They have gone from "It just works" to "It just doesn't work" in no time at all.

And it is Developers who are most pissed off. A tiny demographic who won't be visible on the financial bottom line until their newly absent software suddenly makes itself known two, three years down the line.

By which time it is too late to do anything.

But hey! Look how thin (and thermally throttled) my new laptop is!

Me: you should not open that log file in excel its almost 700mb
Client: its okay, my computer has 4gb ram
Me: *looking at clients computer crashing*
Client: the file is broken!
Me: no, you just need to use a more memory efficient tool, like R, SAS, python, C#, or like anything else!

Senior development manager in my org posted a rant in slack about how all our issues with app development are from

“Constantly moving goalposts from version to version of Xcode”

It took me a few minutes to calm myself down and not reply. So I’ll vent here to myself as a form of therapy instead.

Reality Check:
- You frequently discuss the fact that you don’t like following any of apples standards or app development guidelines. Bit rich to say the goalposts are moving when you have your back to them.

- We have a custom everything (navigation stack handler, table view like control etc). There’s nothing in these that can’t be done with the native ones. All that wasted dev time is on you guys.

- Last week a guy held a session about all the memory leaks he found in these custom libraries/controls. Again, your teams don’t know the basic fundamentals of the language or programming in general really. Not sure how that’s apples fault.

- Your “great emphasis on unit testing” has gotten us 21% coverage on iOS and an Android team recently said to us “yeah looks like the tests won’t compile. Well we haven’t touched them in like a year. Just ignore them”. Stability of the app is definitely on you and the team.

- Having half the app in react-native and half in native (split between objective-c and swift) is making nobodies life easier.

- The company forces us to use a custom built CI/CD solution that regularly runs out of memory, reports false negatives and has no specific mobile features built in. Did apple force this on us too?

- Shut the fuck up

Yesterday was Friday the 13th, so here is a list of my worst dev nightmares without order of significance:

1) Dealing with multithreaded code, especially on Android

2) Javascript callback hell

3) Dependency hell, especially in Python

4) Segfaults

5) Memory Leaks

6) git conflicts

7) Crazy regexes and string manipulations

8) css. Fuck css.

9) not knowing jack shit about something but expected by others to
produce a result with it.

10) 3+ hours of debugging with no success

Post yours

I'm getting ridiculously pissed off at Intel's Management Engine (etc.), yet again. I'm learning new terrifying things it does, and about more exploits. Anything this nefarious and overreaching and untouchable is evil by its very nature.

(tl;dr at the bottom.)

I also learned that -- as I suspected -- AMD has their own version of the bloody thing. Apparently theirs is a bit less scary than Intel's since you can ostensibly disable it, but i don't believe that because spy agencies exist and people are power-hungry and corrupt as hell when they get it.

For those who don't know what the IME is, it's hardware godmode. It's a black box running obfuscated code on a coprocessor that's built into Intel cpus (all Intell cpus from 2008 on). It runs code continuously, even when the system is in S3 mode or powered off. As long as the psu is supplying current, it's running. It has its own mac and IP address, transmits out-of-band (so the OS can't see its traffic), some chips can even communicate via 3g, and it can accept remote commands, too. It has complete and unfettered access to everything, completely invisible to the OS. It can turn your computer on or off, use all hardware, access and change all data in ram and storage, etc. And all of this is completely transparent: when the IME interrupts, the cpu stores its state, pauses, runs the SMM (system management mode) code, restores the state, and resumes normal operation. Its memory always returns 0xff when read by the os, and all writes fail. So everything about it is completely hidden from the OS, though the OS can trigger the IME/SMM to run various functions through interrupts, too. But this system is also required for the CPU to even function, so killing it bricks your CPU. Which, ofc, you can do via exploits. Or install ring-2 keyloggers. or do fucking anything else you want to.

tl;dr IME is a hardware godmode, and if someone compromises this (and there have been many exploits), their code runs at ring-2 permissions (above kernel (0), above hypervisor (-1)). They can do anything and everything on/to your system, completely invisibly, and can even install persistent malware that lives inside your bloody cpu. And guess who has keys for this? Go on, guess. you're probably right. Are they completely trustworthy? No? You're probably right again.

There is absolutely no reason for this sort of thing to exist, and its existence can only makes things worse. It enables spying of literally all kinds, it enables cpu-resident malware, bricking your physical cpu, reading/modifying anything anywhere, taking control of your hardware, etc. Literal godmode. and some of it cannot be patched, meaning more than a few exploits require replacing your cpu to protect against.

And why does this exist?
Ostensibly to allow sysadmins to remote-manage fleets of computers, which it does. But it allows fucking everything else, too. and keys to it exist. and people are absolutely not trustworthy. especially those in power -- who are most likely to have access to said keys.

The only reason this exists is because fucking power-hungry doucherockets exist.

We had the most fucking retarded client today. No, seriously, if you ever beat their level you have a serious mental issue.

They had a mail problem for which they'd need to check at the side of another company since we don't have those fucking logs.

Their statements:
- they entered an email address In the text field of mail-tester.com and were furious that they didn't get the results sent.
Note: it says right on that page that YOU JUST NEED TO SEND THE EMAIL ADDRESS WHICH IS PRE-ENTRRED IN THAT TEXT FIELD AN EMAIL.
- their company has been a reputable 'conservative' company which hasn't done anything wrong since 19xx so the fact that they'd end up on a blacklist was FUCKING OUTRAGEOUS and bullshit.
- our support wasn't willing to help and only willing to tell them outrageous lies.
- the other it company was only reachable at a premium number and thus expensive to call.

Emails back and forth and finally they CC'd the other company. They're reply was fucking priceless:

"we never had a premium number. Feel free to call us on *number* any time during the week between *time* and *time*.

Then he told us that we should just go back to sleep.

It was way worse than that but due to privacy and my own memory this is all I can tell.

Just wow.

My team handles infrastructure deployment and automation in the cloud for our company, so we don't exactly develop applications ourselves, but we're responsible for building deployment pipelines, provisioning cloud resources, automating their deployments, etc.

I've ranted about this before, but it fits the weekly rant so I'll do it again.

Someone deployed an autoscaling application into our production AWS account, but they set the maximum instance count to 300. The account limit was less than that. So, of course, their application gets stuck and starts scaling out infinitely. Two hundred new servers spun up in an hour before hitting the limit and then throwing errors all over the place. They send me a ticket and I login to AWS to investigate. Not only have they broken their own application, but they've also made it impossible to deploy anything else into prod. Every other autoscaling group is now unable to scale out at all. We had to submit an emergency limit increase request to AWS, spent thousands of dollars on those stupidly-large instances, and yelled at the dev team responsible. Two weeks later, THEY INCREASED THE MAX COUNT TO 500 AND IT HAPPENED AGAIN!

And the whole thing happened because a database filled up the hard drive, so it would spin up a new server, whose hard drive would be full already and thus spin up a new server, and so on into infinity.

Thats probably the only WTF moment that resulted in me actually saying "WTF?!" out loud to the person responsible, but I've had others. One dev team had their code logging to a location they couldn't access, so we got daily requests for two weeks to download and email log files to them. Another dev team refused to believe their server was crashing due to their bad code even after we showed them the logs that demonstrated their application had a massive memory leak. Another team arbitrarily decided that they were going to deploy their code at 4 AM on a Saturday and they wanted a member of my team to be available in case something went wrong. We aren't 24/7 support. We aren't even weekend support. Or any support, technically. Another team told us we had one day to do three weeks' worth of work to deploy their application because they had set a hard deadline and then didn't tell us about it until the day before. We gave them a flat "No" for that request.

I could probably keep going, but you get the gist of it.

Google: “Your websites must load the first byte in under 500ms and be fully loaded with no render blocking and local caching of all external site callouts to even begin to rank in Google searches.”

Me: “Ok, Google. Your wish is my command.”

*Looks at Chrome’s memory usage to load a blank page*

Experience that made me feel like a dev badass?

Users requested the ability to 'send' information from one application to another. Couple of our senior devs started out saying it would be impossible (there is no way to pass objects across a machine's memory boundary), then entertained the idea of utilizing the various messaging frameworks such as Microsoft's ServiceBus and RabbitMQ, but came up with a plan to use 2 WebAPI services (one messenger, one receiver) along with a homegrown messaging API (the clients would 'poll' the services looking for message) because ServiceBus, RabbitMQ, etc might not be able to scale to our needs. Their initial estimates were about 6 months development for the two services, hardware requirement for two servers, MSSQL server licenses, and padded an additional 6 months for client modifications. Very...very proud of their detailed planning.

I thought ...hmmm...I've done memory maps and created simple TCP/IP hosts that could send messages back and forth between other apps (non-UI), WPF couldn't be that much different.

In an afternoon, I came up with this (see attached), and showed the boss. Guess which solution we're going with.

The two devs are still kinda pissed at me. One still likes say as I walk in the room "our hero returns"....frack him.

Someone on a C++ learning and help discord wanted to know why the following was causing issues.

char * get_some_data() {
char buffer[1000];
init_buffer(&buffer[0]);
return &buffer[0];
}

I told them they were returning a pointer to a stack allocated memory region. They were confused, didn't know what I was talking about.

I pointed them to two pretty decently written and succinct articles, the first about stack vs. heap, and the second describing the theory of ownership and lifetimes. I instructed to give them a read, and to try to understand them as best as possible, and to ping me with any questions. Then I promised to explain their exact issue.

Silence for maybe five minutes. They disregard the articles, post other code saying "maybe it's because of this...". I quickly pointed them back at their original code (the above) and said this is 100% an issue you're facing. "Have you read the articles?"

"Nope" they said, "I just skimmed through them, can you tell me what's wrong with my code?"

Someone else chimed in and said "you need to just use malloc()." In a C++ room, no less.

I said "@OtherGuy please don't blindly instruct people to allocate memory on the heap if they do not understand what the heap is. They need to understand the concepts and the problems before learning how C++ approaches the solution."

I was quickly PM'd by one of the server's mods and told that I was being unhelpful and that I needed to reconsider my tone.

Fuck this industry. I'm getting so sick of it.

Today, I was told to investigate why the software doesn't work on "some" computers. I had no previous experience with that particular software but I just had to make some tests... easy, right? As soon as I ran the software, my computer crashed (I literally had to restart the pc). I asked my colleagues if I did something wrong but the set up seemed ok.

Later, in a random discussion about the software I found out it does "a little memory allocation". I opened the performance tab in task manager and ran the software again. In an instant, the RAM went from 1.3GB to 7.66GB (my pc has 8GB of RAM).

In an attempt to find how such a monstrosity was creater, I found out the developer that made the software had 16GB of RAM on his pc.

I have found something that eats RAM more than Chrome... brace yourselves.

One of my friend at college asked me why her computer is running slow even when she is running only chrome.

Me: how much memory does it have?
Her: 1TB.
Me (somewhat confused): no no I meant RAM.
Her: yeah yeah it's one TB. I read the specifications of the laptop.
Me: *in my mind, fucking read it again* please read it again. You must have misread it.
Her( grinning face ): alright.

Guess who didn't talk to me for a week. 😂

Every single one of them, and every one that will come after them.

Google, it started out as 2 people in their garage, wanting to make a search engine that was better than the others. Nothing else, nothing evil. Just make the world a little bit better. And look what it's become now. A megacorporation with little to no regards for their user base. Because who cares about users anyway?

Microsoft, it started out with Bill Gates - young high school computer nerd - who wanted to make an operating system for the world to use. Something that's better than the competition. And boy did he do so. Well "better than the competition" aside, he did make it for the world to use. And the world adopted it. And look what it's become now. A megacorporation with little to no regards for their user base. Because who cares about users anyway?

See where I'm going here?

Apple, it started out with Steve Jobs and Steve Wozniak in their garage, just like Google did, wanting to make hardware that was better than the others. Nothing else, nothing evil. Just to make the world a little bit better. And look what it's become now. Planned obsolescence has been baked into it, just like it is in every other piece of technology. Quality control and thinking through the design has become a thing of the past. User choice, yeah who cares about that.

Samsung, it started out centuries ago actually, and I don't really remember the details of it.. ColdFusion has a video on it if memory serves me right. Do watch it if you're interested. Anyway, just like all the others they started out as a company which wanted to make the world a little bit better. And damn right did they do so.. initially. Look what they've become now. Forcing their stupid TouchWiz UI upon their customers (or products?), a Bixby button that can't even be reprogrammed.. and the latest thing.. Knox, advertised as a security feature, but as everyone who likes rooting their devices and mucking with it knows, it is an anti-feature that only serves for lockdown. Why shouldn't you be able to turn in a phone for RMA when a hardware error occurs, when all you've personally modified is the software? Why should changing the software blow that eFuse, so that you can be sure that you can't replace it without specialized equipment and a very steady hand?

I could go on and on forever about more of the tech giants out there, but I feel like this suffices for now. Otherwise I won't have anything else left for future rants! But one thing I know for sure. Every tech company started, starts, and will start out with a desire to make the world a better place, and once they gain a significant customer base, they will without exception turn into the same kind of Evil Megacorp., just like the ones before them. Some may say that capitalism itself is to blame for this, the greed for more when you already have a lot. Who knows? I'd rather say that the very human nature itself is to blame for it. We're by design greedy beings, and I hate it. I hate being human for that. I don't want humans to be evil towards one another, and be greedy for ever more. But I guess that that's just the way it is, and some things do actually never change...

My code review nightmare part 3

Performed a review on/against a workplace 'nemesis'. I didn't follow the department standards document (cause I could care less about spacing, sorted usings, etc) and identified over 80 bugs, logic errors, n+1 patterns, memory leaks (yes, even in .net devs can cause em'), and general bad behavior (ex.'eating' exceptions that should be handled or at least logged)

Because 'Jeff' was considered a golden child (that's another long TL;DR), his boss and others took a major offense and demanded I justify my review, item by item.

About 2 hours into the meeting, our department mgr realized embarrassing Jeff any further wasn't doing anyone any good and decided to take matters into his own hands. Thinking 'well, its about time he did his job', I go back to my desk. About an hour later..
Mgr: "I need you in the conference room, RIGHT NOW!"
<oh crap>
Mgr: "I spoke to Jeff and I think I know what the problem is. Did you ever train him on any of the problems you identified in the review?"
Me: "Um, no. Why would I?"
Mgr: "Ha!..I was right. So lets agree the problems are partially your fault, OK?"
Me: "Finding the bugs in his code is somehow my fault?"
Mgr: "Yes! For example, the n+1 problem in using the WCF service, you never trained him on how to use the service. You wrote the service, correct?"
Me: "Yes, but it's not my job to teach him how to write C#. I documented the process and have examples in the document to avoid n+1. All he had to do was copy/paste."
Mgr: "But you never sat with Jeff and talked to him like a human being? You sit over there in your silo and are oblivious to the problems you cause. This ends today!"
Me: "What the...I have no idea what you are talking about. What in the world did Jeff tell you?"
Mgr: "He told me enough and I'm putting an end to it. I want a compressive training class developed on how to use your service. I'll give you a month to get your act together and properly train these developers."

3 days later, I submit the power-point presentation and accompanying docs. It was only one WCF with a handful of methods. Mgr approved the training, etc..etc. execute the 'training', and Jeff submits a code review a couple of weeks later. From over 80 issues to around 50. The poop hits the fan again.

Mgr: "What's your problem? When are you going to take your responsibility seriously?"
Me: "Its pretty clear I don't have the problem. All the review items were also verified by other devs. Its not me trying to be an asshole."
Mgr: "Enough with the excuses. If you think you can do a better job *you* make the code changes and submit them for Jeff for review. No More Excuses!"

Couple of days later, I make the changes, submit them for review, and Jeff really couldn't say too much other than "I don't see this as an improvement"

TL;DR, I had been tracking the errors generated by the site due to the bugs prior to my changes. After deployment, # of errors went from thousands per hour to maybe hundreds per day (that's another story) and the site saw significant performance increases, fewer customer complaints, etc..etc.

At a company event, the department VP hands out special recognition awards:

VP: "This award is especially well earned. Not only does this individual exemplify the company's focus on teamwork, he also went above and beyond the call of duty to serve our customers. Jeff, come on up and get this well deserved award."

I had to open the desktop app to write this because I could never write a rant this long on the app.

This will be a well-informed rebuttal to the "arrays start at 1 in Lua" complaint. If you have ever said or thought that, I guarantee you will learn a lot from this rant and probably enjoy it quite a bit as well.

Just a tiny bit of background information on me: I have a very intimate understanding of Lua and its c API. I have used this language for years and love it dearly.

[START RANT]

"arrays start at 1 in Lua" is factually incorrect because Lua does not have arrays. From their documentation, section 11.1 ("Arrays"), "We implement arrays in Lua simply by indexing tables with integers."

From chapter 2 of the Lua docs, we know there are only 8 types of data in Lua: nil, boolean, number, string, userdata, function, thread, and table

The only unfamiliar thing here might be userdata. "A userdatum offers a raw memory area with no predefined operations in Lua" (section 26.1). Essentially, it's for the API to interact with Lua scripts. The point is, this isn't a fancy term for array.

The misinformation comes from the table type. Let's first explore, at a low level, what an array is. An array, in programming, is a collection of data items all in a line in memory (The OS may not actually put them in a line, but they act as if they are). In most syntaxes, you access an array element similar to:

array[index]

Let's look at c, so we have some solid reference. "array" would be the name of the array, but what it really does is keep track of the starting location in memory of the array. Memory in computers acts like a number. In a very basic sense, the first sector of your RAM is memory location (referred to as an address) 0. "array" would be, for example, address 543745. This is where your data starts. Arrays can only be made up of one type, this is so that each element in that array is EXACTLY the same size. So, this is how indexing an array works. If you know where your array starts, and you know how large each element is, you can find the 6th element by starting at the start of they array and adding 6 times the size of the data in that array.

Tables are incredibly different. The elements of a table are NOT in a line in memory; they're all over the place depending on when you created them (and a lot of other things). Therefore, an array-style index is useless, because you cannot apply the above formula. In the case of a table, you need to perform a lookup: search through all of the elements in the table to find the right one. In Lua, you can do:

a = {1, 5, 9};
a["hello_world"] = "whatever";

a is a table with the length of 4 (the 4th element is "hello_world" with value "whatever"), but a[4] is nil because even though there are 4 items in the table, it looks for something "named" 4, not the 4th element of the table.

This is the difference between indexing and lookups. But you may say,

"Algo! If I do this:

a = {"first", "second", "third"};
print(a[1]);

...then "first" appears in my console!"

Yes, that's correct, in terms of computer science. Lua, because it is a nice language, makes keys in tables optional by automatically giving them an integer value key. This starts at 1. Why? Lets look at that formula for arrays again:

Given array "arr", size of data type "sz", and index "i", find the desired element ("el"):

el = arr + (sz * i)

This NEEDS to start at 0 and not 1 because otherwise, "sz" would always be added to the start address of the array and the first element would ALWAYS be skipped. But in tables, this is not the case, because tables do not have a defined data type size, and this formula is never used. This is why actual arrays are incredibly performant no matter the size, and the larger a table gets, the slower it is.

That felt good to get off my chest. Yes, Lua could start the auto-key at 0, but that might confuse people into thinking tables are arrays... well, I guess there's no avoiding that either way.

So, some time ago, I was working for a complete puckered anus of a cosmetics company on their ecommerce product. Won't name names, but they're shitty and known for MLM. If you're clever, go you ;)

Anyways, over the course of years they brought in a competent firm to implement their service layer. I'd even worked with them in the past and it was designed to handle a frankly ridiculous-scale load. After they got the 1.0 released, the manager was replaced with some absolutely talentless, chauvinist cuntrag from a phone company that is well known for having 99% indian devs and not being able to heard now. He of course brought in his number two, worked on making life miserable and running everyone on the team off; inside of a year the entire team was ex-said-phone-company.

Watching the decay of this product was a sheer joy. They cratered the database numerous times during peak-load periods, caused $20M in redis-cluster cost overrun, ended up submitting hundreds of erroneous and duplicate orders, and mailed almost $40K worth of product to a random guy in outer mongolia who is , we can only hope, now enjoying his new life as an instagram influencer. They even terminally broke the automatic metadata, and hired THIRTY PEOPLE to sit there and do nothing but edit swagger. And it was still both wrong and unusable.

Over the course of two years, I ended up rewriting large portions of their infra surrounding the centralized service cancer to do things like, "implement security," as well as cut memory usage and runtimes down by quite literally 100x in the worst cases.

It was during this time I discovered a rather critical flaw. This is the story of what, how and how can you fucking even be that stupid. The issue relates to users and their reports and their ability to order.

I first found this issue looking at some erroneous data for a low value order and went, "There's no fucking way, they're fucking stupid, but this is borderline criminal." It was easy to miss, but someone in a top down reporting chain had submitted an order for someone else in a different org. Shouldn't be possible, but here was that order staring me in the face.

So I set to work seeing if we'd pwned ourselves as an org. I spend a few hours poring over logs from the log service and dynatrace trying to recreate what happened. I first tested to see if I could get a user, not something that was usually done because auth identity was pervasive. I discover the users are INCREMENTAL int values they used for ids in the database when requesting from the API, so naturally I have a full list of users and their title and relative position, as well as reports and descendants in about 10 minutes.

I try the happy path of setting values for random, known payment methods and org structures similar to the impossible order, and submitting as a normal user, no dice. Several more tries and I'm confident this isn't the vector.

Exhausting that option, I look at the protocol for a type of order in the system that allowed higher level people to impersonate people below them and use their own payment info for descendant report orders. I see that all of the data for this transaction is stored in a cookie. Few tests later, I discover the UI has no forgery checks, hashing, etc, and just fucking trusts whatever is present in that cookie.

An hour of tweaking later, I'm impersonating a director as a bottom rung employee. Score. So I fill a cart with a bunch of test items and proceed to checkout. There, in all its glory are the director's payment options. I select one and am presented with:

"please reenter card number to validate."

Bupkiss. Dead end.

OR SO YOU WOULD THINK.

One unimportant detail I noticed during my log investigations that the shit slinging GUI monkeys who butchered the system didn't was, on a failed attempt to submit payment in the DB, the logs were filled with messages like:

"Failed to submit order for [userid] with credit card id [id], number [FULL CREDIT CARD NUMBER]"

One submit click later and the user's credit card number drops into lnav like a gatcha prize. I dutifully rerun the checkout and got an email send notification in the logs for successful transfer to fulfillment. Order placed. Some continued experimentation later and the truth is evident:

With an authenticated user or any privilege, you could place any order, as anyone, using anyon's payment methods and have it sent anywhere.

So naturally, I pack the crucifixion-worthy body of evidence up and walk it into the IT director's office. I show him the defect, and he turns sheet fucking white. He knows there's no recovering from it, and there's no way his shitstick service team can handle fixing it. Somewhere in his tiny little grinchly manager's heart he knew they'd caused it, and he was to blame for being a shit captain to the SS Failboat. He replies quietly, "You will never speak of this to anyone, fix this discretely." Straight up hitler's bunker meme rage.

Teacher: Computer settings are stored in the ROM on the motherboard.
Me: *internally* Uhm, yea, sure... and I am the pope
Me: Sorry to interrupt you but how come the BIOS settings get reset when the CMOS battery is pulled out or dies if they are stored in ROM?
Teacher: ....
Me: *internally* yea, that's what I thought, you have no clue what you are even saying - the BIOS is stored in ROM or flash memory while the settings are stored in NVRAM also called CMOS memory...

I taught my 9yo sister to SSH from my Arch Linux system to an Ubuntu system, she was amazed to see terminal and Firefox launching remotely. Next I taught her to murder and eat all the memory (I love Linux, as Batman, one should also know the weaknesses). Now she can rm rf / --no-preserve-root and the forkbomb. She's amazed at the power of one liners. Will be teaching her python as she grew fond of my Raspberry Pi zero w with blinkt and phat DAC, making rainbows and playing songs via mpg123.
I made her use play with Makey Makey when it first came out but it isn't as interesting. Drop your suggestions which could be good for her learning phase?

Storytime
A story about an Android TVbox which decided to become an iPad

Several years ago we've bought an android tv-box. 

It served me and my family well for several years.

Specs are not that important in this story, but there they are:

Android 4.4 
1GB RAM
Amlogic quadcore 1.4HGz
8GB memory.

This device served us well - online TV, browsing, music, file sharing and so on. But recently cheap Chinese memory deciteed to take a break and damaged ROM. Because of that device won't boot. The only option was to take it apart and "short circuit" certain legs on memory chip and make it boot from SD card and install new firmware. After such operations tv-box worked well again. 

Hoverer, memory glitched again and again and this algorithm was repeated for several months.

But that is not what is this story about.

One day memory went completely crazy and there was no way to install new firmware on it. It just hanged on install. (BTW, it was official firmware for this device)

But after countless attempts it finally worked! It installed the firmware and booted into launcher and connected to WiFi! 

But now comes the most interesting part. 

It was not android anymore.

It decided to became an iPad.

My dad logged in to his Google account via tv-box and got mail that someboby connected from our IP via iPad (we don't have an iPad) and using safari browser! Stock browser is not safari browser.....

"Ok, nvm, crazy glitch." - we thought.

But preinstalled play marked wont launch. Because he told us, that we're trying to connect from iPad.

And Google chrome page suggested to download chrome for iPad

And everything was acting like it is an iPad.

OK, downloaded iTunes, why not??? ._.

Tried to install elixir for android via apk from flash, but then memory glitched one more time, everything went black and tv-box had damaged ROM again...

After that we decided to not torment it anymore...

That's it. Poor Android TVbox that all his life dreamed to become an iPad. Rest in peace.

I just mistyped a keyboard shortcut that caused my computer to say «I AM FILO AND EVERYONE LOVES ME» at full volume.
I have no memory of leaving a script attached to some random shortcut, and I can't find the setting anywhere.
Young me was a narcissistic asshole

Here are the reasons why I don't like IPv6.

Now I'll be honest, I hate IPv6 with all my heart. So I'm not supporting it until inevitably it becomes the de facto standard of the internet. In home networks on the other hand.. huehue...

The main reason why I hate it is because it looks in every way overengineered. Or rather, poorly engineered. IPv4 has 32 bits worth, which translates to about 4 billion addresses. IPv6 on the other hand has 128 bits worth of addresses.. which translates to.. some obscenely huge number that I don't even want to start translating.

That's the problem. It's too big. Anyone who's worked on the internet for any amount of time knows that the internet on this planet will likely not exceed an amount of machines equal to about 1 or 2 extra bits (8.5B and 17.1B respectively). Now of course 33 or 34 bits in total is unwieldy, it doesn't go well with electronics. From 32 you essentially have to go up to 64 straight away. That's why 64-bit processors are.. well, 64 bits. The memory grew larger than the 4GB that a 32-bit processor could support, so that's what happened.

The internet could've grown that way too. Heck it probably could've become 64 bits in total of which 34 are assigned to the internet and the remaining bits are for whatever purposes large IP consumers would like to use the remainder for.

Whoever designed IPv6 however.. nope! Let's give everyone a /64 range, and give them quite literally an IP pool far, FAR larger than the entire current internet. What's the fucking point!?

The IPv6 standard is far larger than it should've been. It should've been 64 bits instead of 128, and it should've been separated differently. What were they thinking? A bazillion colonized planets' internetworks that would join the main internet as well? Yeah that's clearly something that the internet will develop into. The internet which is effectively just a big network that everyone leases and controls a little bit of. Just like a home network but scaled up. Imagine or even just look at the engineering challenges that interplanetary communications present. That is not going to be feasible for connecting multiple planets' internets. You can engineer however you want but you can't engineer around the hard limit of light speed. Besides, are our satellites internet-connected? Well yes but try using one. And those whizz only a couple of km above sea level. The latency involved makes it barely usable. Imagine communicating to the ISS, the moon or Mars. That is not going to happen at an internet scale. Not even close. And those are only the closest celestial objects out there.

So why was IPv6 engineered with hundreds of years of development and likely at least a stage 4 civilization in mind? No idea. Future-proofing or poor engineering? I honestly don't know. But as a stage 0 or maybe stage 1 person, I don't think that I or civilization for that matter is ready for a 128-bit internet. And we aren't even close to needing so many bits.

Going back to 64-bit processors and memory. We've passed 32 bit address width about a decade ago. But even now, we're only at about twice that size on average. We're not even close to saturating 64-bit address width, and that will likely take at least a few hundred years as well. I'd say that's more than sufficient. The internet should've really become a 64-bit internet too.

Would the web be better off, if there was zero frontend scripting? There would be HTML5 video/audio, but zero client side JS.

Browsers wouldn't understand script tags, they wouldn't have javascript engines, and they wouldn't have to worry about new standards and deprecations.

Browsers would be MUCH more secure, and use way less memory and CPU resources.

What would we really be missing?

If you build less bloated pages, you would not really need ajax calls, page reloads would be cheap. Animated menus do not add anything functionally, and could be done using css as well. Complicated webapps... well maybe those should just be desktop/mobile apps.

Pages would contain less annoying elements, no tracking or crypto mining scripts, no mouse tracking, no exploitative spam alerts.

Why don't we just deprecate JS in the browser, completely?

I think it would be worth it.

I like memory hungry desktop applications.

I do not like sluggish desktop applications.

Allow me to explain (although, this may already be obvious to quite a few of you)

Memory usage is stigmatized quite a lot today, and for good reason. Not only is it an indication of poor optimization, but not too many years ago, memory was a much more scarce resource.

And something that started as a joke in that era is true in this era: free memory is wasted memory. You may argue, correctly, that free memory is not wasted; it is reserved for future potential tasks. However, if you have 16GB of free memory and don't have any plans to begin rendering a 3D animation anytime soon, that memory is wasted.

Linux understands this. Linux actually has three States for memory to be in: used, free, and available. Used and free memory are the usual. However, Linux automatically caches files that you use and places them in ram as "available" memory. Available memory can be used at any time by programs, simply dumping out whatever was previously occupying the memory.

And as you well know, ram is much faster than even an SSD. Programs which are memory heavy COULD (< important) be holding things in memory rather than having them sit on the HDD, waiting to be slowly retrieved. I much rather a web browser take up 4 GB of RAM than sit around waiting for it to read the caches image off my had drive.

Now, allow me to reiterate: unoptimized programs still piss me off. There's no need for that electron-based webcam image capture app to take three gigs of memory upon launch. But I love it when programs use the hardware I spent money on to run smoother.

Don't hate a program simply because it's at the top of task manager.

"If you ever run out of memory during compiling, get more ram"

No I'm not joking

Him: Relation databases are stupid; SQL injections, complex relationships, redundant syntax and so much more!

Me: so what should we use instead? Mongo, redis, some other fancy new db?

Him: no, I have this class in Java, it loads all the data into memory and handles transfers with http.

Me: ...... Bye!

Why computers are like men:

In order to get their attention, you have to turn them on.
They have a lot of data, but are still clueless.
They are supposed to help you solve problems, but half the time they are the problem.
As soon as you commit to one, you realize that if you had waited a little longer, you could have had a better model.
Why computers are like women:

No one but the Creator understands their internal logic.
The native language they use to communicate with other computers is incomprehensible to everyone else.
Even your smallest mistakes are stored in long-term memory for later retrieval.
As soon as you make a commitment to one, you find yourself spending half your paycheck on accessories for it.

Story, !rant.

This memory came up as I was commenting on another rant, and thought it was worthy of a better retelling.

So about a year or two ago, I had just gotten a Software Defined Radio, and was tinkering with it and looking around for cool stuff I could do with it. After stalking planes for a while (caught a 747 over my area 😎) I saw this program that decoded satellite images of earth, coming from the NOAA satellites. I thought this was amazing.

So I waited until one was over my area and let the software do its magic. The image was not great, since I had this set up on the first floor and there was a lot of material between me and the satellite.

So I came to the brilliant conclusion that I'd leave the program on automatic more (it will start sampling when the satellite is near) on my terrace, which should yield better results, right?

Perhaps. Who knows. Anyways, couple hours pass and we are running late to a family dinner. So we book it. Family dinner was great, good food and all, and was having fun, so never thought about my poor laptop, sitting alone in the night.

But then, when I was walking home in the rain... It hit me. I started running. I couldn't believe what I had done. Fast forward five minutes, and I'm out of breath, but home. I run upstairs, and see the laptop just sitting there, lid open, no lights on, and of course soaked right through.

I couldn't believe it. My only piece of tech at the time, and my only avenue for programming, gone. And I was 15, so I wasn't getting another one any time soon. Took it inside and drained the water out of it, and just left it there lying on its side.

Next day it worked just fine 🤣 the battery on my laptop only lasted max one hour, so by sheer luck it had lost power before the rain came. That is the one time I have to thank that battery for being such utter trash.

Boss wants to scale our webservers because it seems they're having performance/capacity issues....

I'VE BEEN TELLING HIM FOR WEEKS IT'S NOT THE SERVERS!!! IT'S THE FACT THAT EVERY SINGLE QUERY HITS A SINGLE MONGODB... AND NO CACHE EITHER... AND THE DB CANT BE ENTIRELY LOADED INTO MEMORY AS ITS TOO BIG FOR RAM ON A SINGLE SERVER...

HOW THE FUCK CAN YOU SCALE IF EVERYTHING HAS A DEPENDENCY ON 1 NON-DISTRIBUTED DATABASE?

F*cking Samsung's alarm clock.

I really needed to wake up early today so I added secondary alarm little bit earlier. It was supposed to ring at 5:20 and second one shall ring 5:30. But Samsung said no.

Update came thru night and phone was restarted in process. Why it can't keep memory unlocked I don't understand, but OK. But it effectively means it was not able to trigger alarm clock. So I woke up at 6:35 and came more than hour late.

Why such basic functionality failed? My old Sony Erricsson T290i can ring even when powered down. Same as my Nokia and after that Lumia with Windows Phone 10. Why can't Samsung just be normal.

Meet 'SBI Online' app from Play Store, in their own words:

What they were supposed to do?
"Experience the new Retail Internet Banking of SBI"

What they do?
"SBI online app will redirect to SBI Retail Internet Banking (online SBI) site"

Why do they have app?
"No need to remember URL",
"Less memory space required on device"

App storage space?
F**king 2.6 MB, just to redirect users to their website, in third-party browser.

Programmers then:

No problem NASA mate, we can use these microcontrollers to bring men to the moon no problem!

Programmers now:

Help Stack Overflow, my program is kill.. isn't 90GB (looking at you Evolution) and 400GB of virtual memory (looking at you Gitea) for my app completely normal? I thought that unused memory was wasted memory!1!

(400GB in physical memory is something you only find in the most high-end servers btw)

It's march, I'm in my final year of university. The physics/robotics simulator I need for my major project keeps running into problems on my laptop running Ubuntu, and my supervisor suggests installing Mint as it works fine on that.
I backup what's important across a 4GB and a 16GB memory stick. All I have to do now is boot from the mint installation disk and install from there. But no, I felt dangerous. I was about to kill anything I had, so why not `sudo rm -rf /*` ? After a couple seconds it was done. I turned it off, then back on. I wanted to move my backups to windows which I was dual booting alongside Ubuntu.
No OS found. WHAT. Called my dad, asked if what I thought happened was true, and learnt that the root directory contains ALL files and folders, even those on other partitions. Gone was the past 2 1/2 years of uni work and notes not on the uni computers and the 100GB+ other stuff on there.
At least my current stuff was backed up.

TL;DR : sudo rm -rf /* because I'm installing another Linux distro. Destroys windows too and 2 1/2 years of uni work.

When you Valgrind your program for the first time for memory leaks and get "85000127 allocs, 85000127 deallocs, no memory leaks possible"

Looks like /dev/body got tainted.. nasal memory leaks all over the place 😷

$ kill -9 $(pidof cold)

RRRRRRRRREEEEEEEEE!!!! 😣😣😣
I just want to finish my goddamn power supply project, instead of getting bed-ridden by a cold, and running through paper towels like there's no tomorrow 😭

!rant, but you're my friends and I want to share my day...

We've had a problem open since last March (before I started), but our teams identified the issue with the customer's code 2 years ago. No one made progress on it until I took it over. The newest version deployed 3 months ago and has no memory leak. I closed out oldest problem today.

On a personal note, I got quotes for my dj and photographer for my wedding next month, and the price for both is what I would've been willing to pay for one. My wedding was supposed to be very inexpensive, with these and my bartender being the most expensive parts, but due to unfortunate events, my wedding is 4x the cost (have to use a venue, backyard unavailable, which changes ALL my plans).

A few years ago I was browsing Bash.org, and a user posted that he'd physically lost a machine.

A few weeks ago, I'd switched my router out for OPNSense. I figured it was time to start cleaning up my network.

Over the course of tracking down IP addresses and assigning statics to mac addresses, I spotted an IP I didn't recognize.

Being a home network, I'm pretty familiar with everything on the network by IP, so was a little taken aback.

I did some testing, found out that it was a Linux box. Cool.

I can SSH into it. Ok.

Logs show that it's running fine, no CPU/Memory/Harddrive issues. Nice.

So where is it?

Traceroute shows its connected directly to the router... Maybe over an unmanaged switch...

Hostname is "localhost"... That's no help.

I've walked the network 4 times now, and God knows where it is.

I think maybe I'll just leave it alone. If it ain't broke...

I could bitch about XSLT again, as that was certainly painful, but that’s less about learning a skill and more about understanding someone else’s mental diarrhea, so let me pick something else.

My most painful learning experience was probably pointers, but not pointers in the usual sense of `char *ptr` in C and how they’re totally confusing at first. I mean, it was that too, but in addition it was how I had absolutely none of the background needed to understand them, not having any learning material (nor guidance), nor even a typical compiler to tell me what i was doing wrong — and on top of all of that, only being able to run code on a device that would crash/halt/freak out whenever i made a mistake. It was an absolute nightmare.

Here’s the story:

Someone gave me the game RACE for my TI-83 calculator, but it turned out to be an unlocked version, which means I could edit it and see the code. I discovered this later on by accident while trying to play it during class, and when I looked at it, all I saw was incomprehensible garbage. I closed it, and the game no longer worked. Looking back I must have changed something, but then I thought it was just magic. It took me a long time to get curious enough to look at it again.

But in the meantime, I ended up played with these “programs” a little, and made some really simple ones, and later some somewhat complex ones. So the next time I opened RACE again I kind of understood what it was doing.

Moving on, I spent a year learning TI-Basic, and eventually reached the limit of what it could do. Along the way, I learned that all of the really amazing games/utilities that were incredibly fast, had greyscale graphics, lowercase text, no runtime indicator, etc. were written in “Assembly,” so naturally I wanted to use that, too.

I had no idea what it was, but it was the obvious next step for me, so I started teaching myself. It was z80 Assembly, and there was practically no documents, resources, nothing helpful online.

I found the specs, and a few terrible docs and other sources, but with only one year of programming experience, I didn’t really understand what they were telling me. This was before stackoverflow, etc., too, so what little help I found was mostly from forum posts, IRC (mostly got ignored or made fun of), and reading other people’s source when I could find it. And usually that was less than clear.

And here’s where we dive into the specifics. Starting with so little experience, and in TI-Basic of all things, meant I had zero understanding of pointers, memory and addresses, the stack, heap, data structures, interrupts, clocks, etc. I had mastered everything TI-Basic offered, which astoundingly included arrays and matrices (six of each), but it hid everything else except basic logic and flow control. (No, there weren’t even functions; it has labels and goto.) It has 27 numeric variables (A-Z and theta, can store either float or complex numbers), 8 Lists (numeric arrays), 6 matricies (2d numeric arrays), 10 strings, and a few other things like “equations” and literal bitmap pictures.

Soo… I went from knowing only that to learning pointers. And pointer math. And data structures. And pointers to pointers, and the stack, and function calls, and all that goodness. And remember, I was learning and writing all of this in plain Assembly, in notepad (or on paper at school), not in C or C++ with a teacher, a textbook, SO, and an intelligent compiler with its incredibly helpful type checking and warnings. Just raw trial and error. I learned what I could from whatever cryptic sources I could find (and understand) online, and applied it.

But actually using what I learned? If a pointer was wrong, it resulted in unexpected behavior, memory corruption, freezes, etc. I didn’t have a debugger, an emulator, etc. I had notepad, the barebones compiler, and my calculator.

Also, iterating meant changing my code, recompiling, factory resetting my calculator (removing the battery for 30+ sec) because bugs usually froze it or corrupted something, then transferring the new program over, and finally running it. It was soo slowwwww. But I made steady progress.

Painful learning experience? Check.
Pointer hell? Absolutely.

Interesting bug hunt!

Got called in because a co-team had a strange bug and couldn't make sense of it. After a compiler update, things had stopped working.

They had already hunted down the bug to something equivalent to the screenshot and put a breakpoint on the if-statement. The memory window showed the memory content, and it was indeed 42. However, the debugger would still jump over do_stuff(), both in single step and when setting a breakpoint on the function call. Very unusual, but the rest worked.

Looking closer, I noticed that the pointer's content was an odd number, but was supposed to be of type uint32_t *. So I dug out the controller's manual and looked up the instruction set what it would do with a 32 bit load from an unaligned address: the most braindead thing possible, it would just ignore the lowest two address bits. So the actual load happened from a different address, that's why the comparison failed.

I think the debugger fetched the memory content bytewise because that would work for any kind of data structure with only one code path, that's how it bypassed the alignment issue. Nice pitfall!

Investigating further why the pointer was off, it turned out that it pointed into an underlying array of type char. The offset into the array was correctly divisible by 4, but the beginning had no alignment, and a char array doesn't need one. I checked the mapfiles and indeed, the old compiler had put the array to a 4 byte boundary and the new one didn't.

Sure enough, after giving the array a 4 byte alignment directive, the code worked as intended.

Why computers are like men:

1. In order to get their attention, you have to turn them on.
2. They have a lot of data, but are still clueless.
3. They are supposed to help you solve problems, but half the time they are the problem.
4. As soon as you commit to one, you realize that if you had waited a little longer, you could have had a better model.

Why computers are like women:

1. No one but the Creator understands their internal logic.
2. The native language they use to communicate with other computers is incomprehensible to everyone else.
3. Even your smallest mistakes are stored in long-term memory for later retrieval.
4. As soon as you make a commitment to one, you find yourself spending half your paycheck on accessories for it.

Boss: Any idea why ColleagueX's code might be blowing out the memory?

Me (internal): Cos he's a fucking retard who can't code for shit, doesn't listen when I tell him to do stuff properly because he's fucking lazy, has no idea what stack and heap are, uses goto everywhere, doesn't know how to debug, doesn't write any unit tests, and generally WASTES MY FUCKING TIME!

Me (external): Probably a memory leak. I'll take a look.

"...we're using Java. That fat bitch doesn't just eat memory, she just deep-throated her sixth serving and is showing no signs of relenting"

When I was in 8th grade and was learning to code (c++), I sincerely believed that calling a function within a function simply calls it again (like in a loop) . I had never heard of recursion.
And I actually made a small project in which I called a function again and again thinking that calling another terminates the previous one.
No wonder my program kept crashing. I have still kept that code with me as a wonderful memory.

I know this isn't particularly interesting, but I just saw that code today and felt like sharing this...

Saw this on Facebook and couldn't help but share here! 😂

A young woman submitted the tech support message below (about her relationship to her husband) presumably did it as a joke…
The query:

Dear Tech Support,

’Last year I upgraded from Boyfriend 5.0 to Husband 1.0 and noticed a distinct slowdown in overall system performance, particularly in the flower and jewelry applications, which operated flawlessly under Boyfriend 5.0.

In addition, Husband 1.0 uninstalled many other valuable programs, such as: Romance 9.5 and Personal Attention 6.5, and then installed undesirable programs such as: NBA 5.0, NFL 3.0 and Golf Clubs 4.1.

Conversation 8.0 no longer runs, and House cleaning 2.6 simply crashes the system. Please note that I have tried running Nagging 5.3 to fix these problems, but to no avail.
What can I do?

Signed,
Desperate

The response (that came weeks later out of the blue):

Dear Desperate,

“First keep in mind, Boyfriend 5.0 is an Entertainment Package, while Husband 1.0 is an operating system. Please enter command: I thought you loved me.html and try to download Tears 6.2 and do not forget to install the Guilt 3.0 update. If that application works as designed, Husband 1.0 should then automatically run the applications Jewelry 2.0 and Flowers 3.5.

However, remember, overuse of the above application can cause Husband 1.0 to default to Grumpy Silence 2.5, Happy Hour 7.0 or Beer 6.1. Please note that Beer 6.1 is a very bad program that will download the Farting and Snoring Loudly Beta.

Whatever you do, DO NOT, under any circumstances, install Mother-In-Law 1.0 (it runs a virus in the background that will eventually seize control of all your system resources.)
In addition, please, do not attempt to re-install the Boyfriend 5.0 program. These are unsupported applications and will crash Husband 1.0.

In summary, Husband 1.0 is a great program, but it does have limited memory and cannot learn new applications quickly. You might consider buying additional software to improve memory and performance. We recommend: Cooking 3.0.Good Luck!’

Good Luck!

Our team makes a software in Java and because of technical reasons we require 1GB of memory for the JVM (with the Xmx switch).
If you don't have enough free memory the app without any sign just exits because the JVM just couldn't bite big enough from the memory.
Many days later and you just stand there without a clue as to why the launcher does nothing.
Then you remember this constraint and start to close every memory heavy app you can think of. (I'm looking at you Chrome) No matter how important those spreadsheets or illustrator files. Congratulation you just freed up 4GB of memory, things should work now! WRONG!
But why you might ask. You see we are using 32-bit version of java because someone in upper management decided that it should run on any machine (even if we only test it on win 7 and high sierra) and 32 is smaller than 64 so it must be downwards compatible! we should use it! Yes, in 2019 we use 32-bit java because some lunatic might want to run our software on a Windows XP 32-bit OS. But why is this so much of a problem?
Well.. the 32-bit version of Java requires CONTIGUOUS FREE SPACE IN MEMORY TO EVEN START... AND WE ARE REQUESTING ONE GIGABYTE!!
So you can shove your swap and closed applications up your ass but I bet you that you won't get 1GB contiguous memory that way!
Now there will be a meeting about this issue and another related to the issues with 32-bit JVM tomorrow. The only problem is that this issue only occures if you used up most of your memory and then try to open our software. So upper management will probably deem this issue minor and won't allow us to upgrade to 64-bit... in 20fucking19

Oh no! A memory overread - you better delete VLC - Gizmodo

TFW you spend 30 minutes debugging an app that isn't working right only to find out it's working exactly as it's supposed you, you just forgot you put that bit in there that does that thing.

One character change later and it's working perfectly. ONE CHARACTER! THIRTY BASTARD MINUTES! I just spent thirty minutes driving through every line of code and coming closer to the conclusion that Java was doing some kind of strange thing with dropping objects from memory. No, it wasn't Java that had memory problems, it's me! Just check me into the old peoples home now so I can spend my day pissing my pants and making lewd comments at the nurses because that's all I'm fucking useful for at this point!!

I need a coffee.

Just commented on a rant
*Goes back to scrolling*
*Remembers that I forgot to ++ it*
*Runs to my comments to upvote the rant*

Happened to anyone else?

I've got a file on my desktop called key.txt, and it's just a single line in it that is clearly some sort of API key.

Absolutely no memory of what it is for.

Ok friends let's try to compile Flownet2 with Torch. It's made by NVIDIA themselves so there won't be any problem at all with dependencies right?????? /s

Let's use Deep Learning AMI with a K80 on AWS, totally updated and ready to go super great always works with everything else.

> CUDA error
> CuDNN version mismatch
> CUDA versions overwrite
> Library paths not updated ever
> Torch 0.4.1 doesn't work so have to go back to Torch 0.4
> Flownet doesn't compile, get bunch of CUDA errors piece of shit code
> online forums have lots of questions and 0 answers
> Decide to skip straight to vid2vid
> More cuda errors
> Can't compile the fucking 2d kernel
> Through some act of God reinstalling cuda and CuDNN, manage to finally compile Flownet2
> Try running
> "Kernel image" error
> excusemewhatthefuck.jpg
> Try without a label map because fuck it the instructions and flags they gave are basically guaranteed not to work, it's fucking Nvidia amirite
> Enormous fucking CUDA error and Torch error, makes no sense, online no one agrees and 0 answers again
> Try again but this time on a clean machine
> Still no go
> Last resort, use the docker image they themselves provided of flownet
> Same fucking error
> While in the process of debugging, realize my training image set is also bound to have bad results because "directly concatenating" images together as they claim in the paper actually has horrible results, and the network doesn't accept 6 channel input no matter what, so the only way to get around this is to make 2 images (3 * 2 = 6 quick maths)
> Fix my training data, fuck Nvidia dude who gave me wrong info
> Try again
> Same fucking errors
> Doesn't give nay helpful information, just spits out a bunch of fucking memory addresses and long function names from the CUDA core
> Try reinstalling and then making a basic torch network, works perfectly fine
> FINALLY.png
> Setup vid2vid and flownet again
> SAME FUCKING ERROR

> Try to build the entire network in tensorflow
> CUDA error
> CuDNN version mismatch
> Doesn't work with TF
> HAVE TO FUCKING DOWNGEADE DRIVERS TOO
> TF doesn't support latest cuda because no one in the ML community can be bothered to support anything other than their own machine
> After setting up everything again, realize have no space left on 75gb machine
> Try torch again, hoping that the entire change will fix things

At this point I'll leave a space so you can try to guess what happened next before seeing the result.

Ready?

> SAME FUCKING ERROR

In conclusion, NVIDIA is a fucking piece of shit that can't make their own libraries compatible with themselves, and can't be fucked to write instructions that actually work.

If anyone has vid2vid working or has gotten around the kernel image error for AWS K80s please throw me a lifeline, in exchange you can have my soul or what little is left of it

Why do people jump from c to python quickly. And all are about machine learning. Free days back my cousin asked me for books to learn python.
Trust me you have to learn c before python. People struggle going from python to c. But no ml, scripting,

And most importantly software engineering wtf?
Software engineering is how to run projects and it is compulsory to learn python and no mention of got it any other vcs, wtf?

What the hell is that type of college. Trust me I am no way saying python is weak, but for learning purpose the depth of language and concepts like pass by reference, memory leaks, pointers.

And learning algorithms, data structures, is more important than machine learning, trust me if you cannot model the data, get proper training data, testing data then you will get screewed up outputs. And then again every one who hype these kinds of stuff also think that ml with 100% accuracy is greater than 90% and overfit the data, test the model on training data. And mostly the will learn in college will be by hearting few formulas, that's it.

Learn a language (concepts in language) like then you will most languages are easy.

Cool cs programmer are born today😖

Is obsidian a fucking joke?

Seriously, is it a joke? Why would you ever care so much about indexing literally everything, if the entire thing crashes and/or takes >5min to LITERALLY just open the fucking directory and/or (so help you) if that directory is full of projects/repos or whatever the fuck and the total size of said directory is like >5GB.

WHY THE FUCK WOULD YOU INDEX EVERYTHING? -- "Ohh obsidian's not supposed to be used a fully fledged IDE, ohh obsidian should just handle MD files and normal sized projects, ohh the plugins and ease-of-use" -- Fuck.

There's no fucking real reason to index everything, BY DEFAULT. You open a directory with Obsidian? Doesn't matter, it's 1 byte, it's 100GB, you get indexed. Deal with it. It will use LITERALLY every resource your computer has. I'm surprised it doesn't go galaxy brain and ping if any other computers/devices are on the network and then attempt to connect and use their hardware (obsidian can be like a node!).

How shit can you be at understanding basic data structures and algorithms, where you just revert to based google-chrome brain and let the FUCKING TEXT EDITOR -- OBSIDIAN IS A FUCKING TEXT EDITOR HOLY SHIT -- hog all conceivable memory.

I swear to <some-deity> if anyone fucking says "Ohhhhhhhh actually, it's not a text editor, it has plugins and features and shit, it does all dis cool stff", OR, "Ohhhhh actually, obsidian indexes things for a very specific/rationale/apt/pragmatic/academic reason" OR "ohhhh, I have 100 iphones, 1000 ipads and a trillion desktop computers that each have 256GB of memory, why you hating on obsidian?" then go kick rocks. The fucking lot of you. Are you fucking kidding me.

LPT: NEVER accept a freelance job without looking at the project's source first

Client: I have a project made by a company that is now abandoning it, I want you to fix some bugs

Me: Okay, can you:
1) Give me a build to test the current state of the game
2) Tell me what the bugs are
3) Show me the source
4) Tell me your budget

Client: *sends a list of 10 bugs* Here's the APK and to give you the project I'll need you to sign an NDA

Me: Sure...

*tests build*
*sees at least 20 bugs*
*still downloading source*
*bugs look quite easy to fix should be done under an hour*

Me: Okay, so, I can fix each bug for $10 and I can do 2 today

Client: Okay can you fix 8 bugs today for $40??

*sigh*

Me: No I cannot.

Client: okay then 2 today for $20 is fine, I want a refund if you can't fix them today

*sigh*

Me: Look dude, this isn't the first time I am doing this, aight? I'll fix the bugs today you can pay me after check they are done, savvy?

Client: okay

*source is downloaded*
*literal apes wrote the scripts, commented out code EVERYWHERE
Debug logs after every line printing every frame causing FPS drops, empty objects in the scene
multiple unused UI objects
everything is spaghetti*

*give up, after 2 hours of hell*
*tfw averted an order cancellation by not taking the order and telling client that they can pay me after I am done*

Attached is an image of a level object pool
It's an array with each element representing a level.
The numbers and "Final" are ids for objects in an object pool
The whole string is .Split(',') into an array (RIP MEMORY BTW) and then a loop goes through each element in the split array and instantiates the object from an object pool

You know what just gets to me about garbage-collected languages like c# and Java? Fucking dynamic memory allocation (seemingly) on the stack. Like it's so bizzare to me.

"Hey, c#, can I have an array of 256 integers during run-time?"

"Ya sure no prob"

"What happens when the array falls out of scope"

"I gotchu fam lol"

MacRant: was waiting for a new macbook pro release for awhile to upgrade by old laptop (not mac). Watched the release, had very mixed feeling about it, but still ordered (clinching my teeth and saying sorry to my wallet). Next day looked into alternatives, cacelled the orded to have more time to think, now deciding... I mean cmon, no latest 7th gen processor, no 32gb memory option, 2gb video is ok for non gaming, the whole "big" thing is TouchBar that I DON'T F* NEED. They should drop the "Pro" and name it "Fancy Strip".

So I looked into alternatives, and Dell XPS 15 with maxed spect is twice as juicier, and has not a touch bar, but the whole touch freakin 4k screen, for the less price :/
Just wanted to rant about the new macbook's spec and price and see what you all think of macbook vs alternatives?

I do not like the direction laptop vendors are taking.

New laptops tend to feature fewer ports, making the user more dependent on adapters. Similarly to smartphones, this is a detrimental trend initiated by Apple and replicated by the rest of the pack.

As of 2022, many mid-range laptops feature just one USB-A port and one USB-C port, resembling Apple's toxic minimalism. In 2010, mid-class laptops commonly had three or four USB ports. I have even seen an MSi gaming laptop with six USB ports. Now, much of the edges is wasted "clean" space.

Sure, there are USB hubs, but those only work well with low-power devices. When attaching two external hard drives to transfer data between them, they might not be able to spin up due to insufficient power from the USB port or undervoltage caused by the impedance (resistance) of the USB cable between the laptop's USB port and hub. There are USB hubs which can be externally powered, but that means yet another wall adapter one has to carry.

Non-replaceable [shortest-lived component] mean difficult repairs and no more reserve batteries, as well as no extra-sized battery packs. When the battery expires, one might have to waste four hours on a repair shop for a replacement that would have taken a minute on a 2010 laptop.

The SD card slot is being replaced with inferior MicroSD or removed entirely. This is especially bad for photographers and videographers who would frequently plug memory cards into their laptop. SD cards are far more comfortable than MicroSD cards, and no, bulky external adapters that reserve the device's only USB port and protrude can not replace an integrated SD card slot.

Most mid-range laptops in the early 2010s also had a LAN port for immediate interference-free connection. That is now reserved for gaming-class / desknote laptops.

Obviously, components like RAM and storage are far more difficult to upgrade in more modern laptops, or not possible at all if soldered in.

Touch pads increasingly have the buttons underneath the touch surface rather than separate, meaning one has to be careful not to move the mouse while clicking. Otherwise, it could cause an unwanted drag-and-drop gesture. Some touch pads are smart enough to detect when a user intends to click, and lock the movement, but not all. A right-click drag-and-drop gesture might not be possible due to the finger on the button being registered as touch. Clicking with short tapping could be unreliable and sluggish. While one should have external peripherals anyway, one might not always have brought them with. The fallback input device is now even less comfortable.

Some laptop vendors include a sponge sheet that they want users to put between the keyboard and the screen before folding it, "to avoid damaging the screen", even though making it two millimetres thicker could do the same without relying on a sponge sheet. So they want me to carry that bulky thing everywhere around? How about no?

That's the irony. They wanted to make laptops lighter and slimmer, but that made them adapter- and sponge sheet-dependent, defeating the portability purpose.

Sure, the CPU performance has improved. Vendors proudly show off in their advertisements which generation of Intel Core they have this time. As if that is something users especially care about. Hoo-ray, generation 14 is now yet another 5% faster than the previous generation! But what is the benefit of that if I have to rely on annoying adapters to get the same work done that I could formerly do without those adapters?

Microsoft has also copied Apple in demanding internet connection before Windows 11 will set up. The setup screen says "You will need an Internet connection…" - no, technically I would not. What does technically stand in the way of Windows 11 setting up offline? After all, previous Windows versions like Windows 95 could do so 25 years earlier. But also far more recent versions. Thankfully, Linux distributions do not do that.

If "new" and "modern" mean more locked-in and less practical and difficult to repair, I would rather have "old" than "new".

My Manager: How is the progress so far on the search module?

Me(After implementing some crazy shit requirements): It's all set. APIs are working well against the mock in-memory database. I need an actual database to run my unit tests. Where do we have it?

My manager: Let's pretend that there is no database at this moment. Go-ahead with rest of your activities.

Me(IN MY MIND): F*CK you a** hole. You don't know the first thing of software development! Which a** hole promoted you as a manager!!!

Me(TO HIS FACE): Ah.. okay!! As you wish!

Feature request: We want an android backup solution in Our app!
UI guy has already developed it, you just need to see if his solution is solid!
Ok then - lets look at the UI: Nice progress bars, that turn into green checkmarks. Looks good.
Now lets look at the code: ... Ok. loading some files into memory.... and... dafuq? does not write to a file?

Backup to RAM. With no restore. 🤦‍♂️.

FFUUUuucccckkk me sideways. So I decided to look into USB type-c's power delivery and alt modes. Cause I kinda want to make an adapter card to run my displays over a single cable. TLDR of the rest: USB-C has some huge capabilities which noone is interested in using since its way to complex to handle for what its worth in the end.
Now PD alone is kinda ok to deal with since a lot of powerbanks use it and some hobby guys documented how to work with it. I find it really odd thou that you NEED to use a dedicated IC for using the configuration chanel to negotiate how much power you can draw. Why the USB standard didnt use some simple 5V low speed signalling? Also the standard says that you only have to implement 5v 0.6A with every other power level being optional. (This is also true for cables. Most manufacturers use only the USB 2.0 standard for them and brag about how fast type-C is. ლ(ಠ益ಠლ) )
Now to the alt modes. These motherfuckers are a real shitshow to deal with. First you need a Mux to deal with USB-C's two way insertion, so your signals wont get flipped. Next thing is that you have four lanes at your disposal in alt mode. Which you can either use for four Display Port Lanes or two DP lanes and two USB 3.0 lanes. (You always get USB 2.0) Now you may think that there would be one simple chip to do it all? Nope you need atleast two at the price of 6$ each. One for PD and one for Alt modes. Both are very hard to solder (QFN, 0.5 mm pitch 40+ pins) TI ended up being the only one with a decent offering of IC's that do what I need. As for working with them, you would think that you just slap a simple MCU on there that communicates over I2C or SPI to configure the chips? Nope! You program the chips memory from which it configures itsself. And the programming is done with some TI tool which gives me no idea as to how you can handle everything whith no control logic behind it.
Looking into alternative IC's leaves me with cypress semi. And their documentation is basically a total mess. I wanna know what that chip is good for and what I need to do to make it work. I dont care about technical details mixed with marketing jargon nobody understands. And I really despise that I have to register just to download a datasheet. Especially since there is no info about it on the main page.
And this whole rant hasnt even touched the topic that USB-C only uses DP and nothing else. So you better hope that you have DP++ so you can use a passive conversion.
This was my Ted Talk about USB-C. Some info in it may be subject to my stupidity and errors as it currently is 02:15 in the morning and I need some sleep.

University Coding Exam for Specialization Batch:
Q. Write a Program to merge two strings, each can be of at max 25k length.
Wrote the code in C, because fast.
Realized some edge cases don't pass, runtime errors. Proceed on to check the locked code in the Stub. (We only have to write methods, the driver code is pre-written)
Found that the memory for the char Arrays is being allocated dynamically with size 10240.
Rant #1:
Dafuq? What's the point of dynamic Memory Allocation if you're gonna fix it to a certain amount anyway?
Continuing...
Called the Program Incharge, asking him to check the problem and provide a solution. He took 10 minutes to come, meanwhile I wrote the program in Java which cleared all the test cases. <backstory>No University Course on Java yet, learnt it on my own </backstory>
Dude comes, I explain the problem. He asks me to do it in C++ instead coz it uses the string type instead of char array.
I told him that I've already done it in Java.
Him: Do you know Java?

Rant #2:
No you jackass! I did the whole thing in Java without knowing Java, what's wrong with you!

“Hey - just calling you to give you an update”

Great - sorry can you refresh my memory what was this for?

“So I was about to put you through for a client but they’re no longer accepting CVs so just to update you that’s not happening”

Sorry, what was the client again?

“Oh I can’t say, but they’re no longer accepting CVs”

“...Thanks, goodbye.”

*So you call me to tell me that you can’t give my details to a client that you can’t disclosure....get off my line 🤬😡🤬*

Windows 10 wants to ruin my life by consuming almost 70% of memory for itself from 4 gigs.
No application is running and still consuming that much of memory. Now I just hate the updates of windows 10 pro.

Any suggestions to get rid of this situation?

I propose that the study of Rust and therefore the application of said programming language and all of the technology that compromises it should be made because the language is actually really fucking good. Reading and studying how it manages to manipulate and otherwise use memory without a garbage collector is something to be admired, illuminating in its own accord.

BUT going for it because it is a "beTter C++" should not constitute a basis for it's study.

Let me expand through anecdotal evidence, which is really not to be taken seriously, but at the same time what I am using for my reasoning behind this, please feel free to correct me if I am wrong, for I am a software engineer yes, I do have academic training through a B.S in Computer Science yes, BUT my professional life has been solely dedicated to web development, which admittedly I do not go on about technical details of it with you all because: I am not allowed to(1) and (2)it is better for me to bitch and shit over other petty development related details.

Anecdotal and otherwise non statistically supported evidence: I have seen many motherfuckers doing shit in both C and C++ that ADMIT not covering their mistakes through the use of a debugger. Mostly because (A) using a debugger and proper IDE is for pendejos and debugging is for putos GDB is too hard and the VS IDE is waaaaaa "I onlLy NeeD Vim" and (B) "If an error would have registered then it would not have compiled no?", thus giving me the idea that the most common occurrences of issues through the use of the C father/son languages come from user error, non formal training in the language and a nice cusp of "fuck it it runs" while leaving all sorts of issues that come from manipulating the realm of the Gods "memory".
EVERY manual, book, coming all the way back to the K&C book talks about memory and the way in which developers of these 2 languages are able to manipulate and work on it. EVERY new standard of the ISO implementation of these languages deals, through community effort or standard documentation about the new items excised through features concerning MODERN (meaning, no, the shit you learned 20 years ago won't fucking cut it) will not cut it.

THUS if your ass is not constantly checking what the scalpel of electrical/circuitry/computational representation of algorithms CONDONES in what you are doing then YOU are the fucking problem.

Rust is thus no different from the original ideas of the developers behind Go when stating that their developers are not efficient enough to deal with X language, Rust protects you, because it knows that you are a fucking moron, so the compiler, advanced, and well made as it is, will give you warnings of your own idiotic tendencies, which would not have been required have you not been.....well....a fucking idiot.

Rust is a good language, but I feel one that came out from the necessity of people writing system level software as a bunch of fucking morons.
This speaks a lot more of our academic endeavors and current documentation than anything else. But to me DEALING with the idea of adapting Rust as a better C++ should come from a different point of view.

Do I agree with Linus's point of view of C++? fuck no, I do not, he is a kernel engineer, a damn good one at that regardless of what Dr. Tanenbaum believes(ed) but not everyone writes kernels, and sometimes that everyone requires OOP and additions to the language that they use. Else I would be a fucking moron for dabbling in the dictionary of languages that I use professionally.
BUT in terms of C++ being unsafe and unsecured and a horrible alternative to Rust I personaly do not believe so. I see it as a powerful white canvas, in which you are able to paint software to the best of your ability WHICH then requires thorough scrutiny from the entire team. NOT a quick replacement for something that protects your from your own stupidity BY impending the use of what are otherwise unknown "safe" features.

To be clear: I am not diminishing Rust as the powerhouse of a language that it is, myself I am quite invested in the language. But instead do not feel the reason/need before articles claiming it as the C++ killer.

I am currently heavily invested in C++ since I am trying a lot of different things for a lot of projects, and have been able to discern multiple pain points and unsafe features. Mainly the reason for this is documentation (your mother knows C++) and tooling, ide support, debugging operations, plethora of resources come from it and I have been able to push out to my secret project a lot of good dealings. WHICH I will eventually replicate with Rust to see the main differences.

Online articles stating that one will delimit or otherwise kill the other is well....wrong to me. And not the proper approach.

Anyways, I like big tits and small waists.

This is my first rant here, so I hope everyone has a good time reading it.

So, the company I am working for got me going on the task to do a rewrite of a firmware that was extended for about 20 years now. Which is fine, since all new machines will be on a new platform anyways. (The old firmware was written for an 8051 initially. That thing has 256 byte of ram. Just imagine the usage of unions and bitfields...)

So, me and a few colleagues go ahead and start from scratch.
In the meantime however, the client has hired one single lonely developer. Keep in mind that nobody there understands code!
And oh boy did he go nuts on the old code, only for having it used on the very last machine of the old platform, ever! Everything after that one will have our firmware!

There are other machines in that series, using the original extended firmware. Nothing is compatible, bootloaders do not match, memory layouts do not match, code is a horrible mess now, the client is writing the specification RIGHT NOW (mind, the machine is already sold to customers), there are no tests, and for the grand finale, the guy canceled his job and went to a different company. Did I mention the bugs it has and the features it lacks?

Guess who's got to maintain that single abomination of a firmware now?

Well I'm a first year student in computer science and in the first semester we started to learn C language and the IDE they told us to use for better learning was Devcpp.
We made a few small projects and all went well, but now in the second semester we started to make bigger projects with linked lists and memory allocation and Devcpp starts to be a complete bug itself... We are working hard in the project and after saving the project with no errors at all, at the next day, Devcpp starts to make any function we made invalid...
So we spoke to the same teacher about this and asked what can we do about it....
"Are you using Devcpp? You shouldn't, it is not that good for C"...
ARE YOU KIDDING ME?

The only thing more dangerous than an alcoholic short-term-memory-challenged non-technical throw-you-under-the-bus IT director with self-esteem issues that are sporadically punctuated by delusions of superiority is one who fears for his job. Submitted for your inspection: a besotted mass of near-human brain function who not only has a 50 person IT department to run, but has also been questioned by the business owners as to what he actually does. So he has decided to show them. He has purchased a vendor product to replace a core in-house developed application used to facilitate creating the product the business sells. The purchased software only covers about 40 percent of the in-house application's functionality, so he is contracting with the vendor to perform custom development on the purchased product (at a cost likely to be just shy of six-figures) so that about 90 percent of existing functionality will be covered. He has asked one of his developers (me) to scale down the existing software to cover the functionality gaps the purchased software creates. There is no deployment plan that will allow the business to transition from the current software to the new vendor​-supplied one without significantly hurting the ability of the business to function. When anyone raises this issue he dismisses it with sage musings such as, "I know it will be painful, but we'll just have to give the users really good support." Because he has no idea what any of his staff actually does, he is expecting one of his developers (again, unfortunately, me) to work with the vendor so that the Frankensoftware will perform as effectively as the current software (essentially as a project manager since there will be no in-house coding involved). Lastly, he refuses to assign someone to be responsible for the software: taking care of maintenance, configuration, and issue resolutions after it has been rolled out. When I pointedly tell him I will not be doing that (because this is purchased software and I am not a system admin or desktop engineer) he tells me, "Let me think about this." The worst part is that this is only one of four software replacement initiatives he is injecting himself into so he can prove his worth to the business owners. And by doing so he is systematically making every software development initiative akin to living in Dante's Eighth Circle. I am at the point where I want to burn my eye out with a hot poker, pour salt into the wound, and howl to the heavens in unbearable agony for a month, so when these projects come to fruition, and I am suffering the wrath of the business owners, I can look back on that moment I lost my eye and think "good times."

So I've started learning Rust and I must say it feels great! But some parts of the language, like enums, are quite different than what I'm used to.
As a proof of concept I've reimplemented a small API (an Azure Function App) in Rust with Actix Web and it's FAST AS FUCK BOIII.
The response is served about 5x as quckly and the memory footprint shrinked from some 90 MB to around 5 MB.
In my small scale usecase it's not a huge difference, but I think it can be massive at large scales...
What is your experience with Rust (at scale)?

I wish I could quickly reimplement the whole fucking CMS Of Doom™ in Rust... but no time and resources :(

A child's mind is fascinating.

I remember how it felt being a kid, just deliriously happy.

Things were magical, mystical and happy.

I knew the world wasn't perfect, I knew bad things happened to good people.

But a kid's mind is so powerful that it can fill in the blanks with the most cheerful and optimistic perspectives.

And at some point in my childhood I was exposed to videogames, and that kinda took me down fantasy lane even further.

I was extremely young and barely retaining any memories when I was exposed to my first console, a famicom.

I have a somewhat vivid memory of my mind being blown away for the first time by watching my brother play New Ghostbusters II for NES.

From then on, we never stopped and played several console and dos/pc games.

When I was 10, someone from the neighborhood brought in a couple of floppys with Pokemon Yellow.

"What? Pokemon? How the fuck is that even possible? This is a pc, not a gameboy".

I didn't know at the time what an emulator was, but I was super fucking stoked to be able to play that.

My dad had a 1 gb laptop from work that he didn't use, so I hoarded that shit, and I would get to bed and play nearly everyday.

The experience was surreal. I was doing pc gaming... not on a chair, on a fucking bed, and I was playing a gameboy game... on a pc.

It was so intense to me, that even after more than 2 decades of that time in my life, I still remember how it feels like.

Like, you know how you can "feel" things if you think about them? like for example if you think about the taste of chicken, you can somehow feel it for a second.

Well I have like an actual physical sensation linked to that experience but I can't explain it at all, because it's just a sensation.

I think people usually say they feel that way, for example, about the PSX (usually refered to as ps one) loading screen. I experienced that too but when I was 12, so it was not as intense (it does make me feel the fuzzies though).

I also remember other things with very high detail, like the texture of my bed cover, the weather, mom cooking, the clunky shape of the laptop, the way I carelessly stored it above a pile of magazines, etc.

I rememeber ofc how it felt looking at the game sprites, interacting with NPCs, and the goddamn fucking glorious music.

It was dreamy.

Years and years later, I grew up and I stopped living in fantasy world and became more aware of the grim aspects of life my younger self was sugarcoating.

So I tried to play pokemon again, again and again, and no matter how hard I tried to revive that euphoria, I could not never do it.

I started to get annoyed at the game.

"Come oooon, I did the tutorial already, let me skip this.
This pokemon is useless, why am I even training it.
Fuck, I'm tired of grinding"

At some point I accepted that the feeling would never return, and that it would just live in my memory.

Ironically, I can recall that memory and how it felt anytime I want to.

And I can actually still feel it, and throughtout these years, it has never wore down.

And eventually I learned how to play pokemon and enjoy it:

I read tier lists at smogon online and just catch and train the pokemons that are higher on the list, which is how i got to beat yellow in like 3 days.

(This is nothing compared to what speedrunners do, but much better than the weeks it had taken me in the past).

That served as an important lesson that when a kid plays a game, his mind is also the game at the same time, filling the blanks with its imagination.

A very similar experience happened to me with harvest moon, which is the precursor of stardew valley.

and that game is faaar more emotional: you talk to people, overtime you befriend them and they open up, you meet a girl, you marry her, have a kid

you get farm animals, you brush them, they become happy

you get attached

that game was also so powerful in me that in all naiveness I thought I wanted to be a farmer.

Eventually I grew up and hit puberty and from then on, I focused more on competitive games, like smash bros, cs and tf2.

and i dunno how to end a post so eat my fucking nuts

Today’s lesson in C programming:

DON’T use
system( “clear” );
in Mac OS...
Causes seg Fault in ur program when it is perfectly correct...

What happened was... a friend wanted help with C programming and had written this code... but it was getting seg Fault randomly... just random seg Fault when his code was correct...

I pinpointed the seg Fault to a printf statement but the statement was correct...

Off to search the issue I went, found out that flushing problems can occur in printf if u don’t use \n.
This happens randomly. Thought this might b the reason...
Went to a VM running Arch Linux and tested the code there... worked perfectly. No issues whatsoever.

From a distant memory I remembered some people discussing to never use system( “clear” ); since it causes issues.
Thought to remove that line from code, thinking it wouldn’t make any difference.
Well imagine my shock when the code worked fine after remove that freaking line...

M gonna blame this one on Mac OS since arch had no issues with it 😡😡

Now to find alternative to system( “clear” );

Damm it I spent 4-5 hours on this crap!!!!!!

My first contact with an actual computer was the Sinclair ZX80, a monster with 512 bytes of ram (as in 1/2 kbyte)

It had no storage so you had to enter every program every time and it was programmed in basic using key combinations, you could not just write the commands since it did not have memory enough to keep the full text in memory.

So you pressed the cmd key along with one of the letter keys and possibly shift to enter a command, like cmd+p for print and it stored s byte code.

Spent 6 hours implementing a feature because my senior didn't want to use a 3rd party plug-in.

After said 6 hours, went to look at the plugin's source code to get some inspiration with a problem I was having.

Guess fucking what? Plug-in was implemented exactly as I had done it to start with. Even better, actually, since it fixed some native bugs I couldn't find a way around.

Went back to my senior, showed him both sources and argued again in favour of the plug-in.

Senior: "Meh, I'm not sure. Don't really like to keep adding plugins"
Me: "Why? Do they cause performance hits? Increase memory usage?"
S: "No, not all. But I don't like plugins"

/flip

We ended up using the plug-in, but I "wasted" a whole day doing something we scrapped. Guess I learned some interesting things about encryption on Android, at least...

Four years ago while still a newbey in Android Dev and still using the eclipse IDE which was hell to configure by adding Android plugins,my girlfriend had a birthday.
With my new found love of coding thought of developing a b-day app for her.With so little android knowledge I had a great idea the main activity would have her photo as the background and button which when clicked would show a toast saying happy b-day love.
After spending few minutes in Tutorial point and learning how to display a toast and setting click listeners on buttons I was good to go and compiled the app.

Later that evening I head to her room where her b-day was to be held with some of her lady friends .When presenting gifts I presented her gift said had one more surprise for her and asked for her phone and using bluetooth sent the apk to her phone.
Installing the app I was scared to death on seeing how my grey buttons were displaying on her 2.7 screen size since had no idea on designing for multiple screens.
Giving her back the phone she loved the app and felt like her superman in the room though not for long.Her lady friends had gone ahead took her phone and were critising the app:
Why can't I take a selfie
Why can't the app play a b-day song for her and this went on them not knowing how hurting that was.
Bumped on the lady who lead the onslaught on me and had to go down memory lane.Life is a journey.

I just installed Opera Mini on my PSP. That alone isn't very exciting on its own, although I am stoked that my website does in fact render on a device from 2009. With the helpful guidance of a laptop from 2004 that's doing the hotspot duties for this thing.

No, what really got me stoked is that Opera still supports these old platforms, and how small they managed to make it. The .jar file for Opera Mini 4.5 is ~800kB large. There's a .jad file as well but it's negligible in size and seems to be a signature of sorts.

Let that sink in for a moment. This entire web browser is 800kB. Firefox meanwhile consistently consumes 800 MEGABYTES.. in MEMORY. So then, I went to think for a moment, how on earth did they manage to cram an entire functioning web browser in 800kB? Hell, what makes up a web browser anyway?

The answer to that question I got to is as follows. You need an engine to render the web page you receive. You need a UI to make the browser look nice. And finally you need a certificate store to know which TLS certificates to trust. And while probably difficult to make, I think it should be possible to do in 800k. Seriously, think about it. How would you go *make* a web browser? Because I've already done that in the past.

Earlier I heard that you need graphics, audio, wasm, yada yada backends too.. no. Give your head a shake. Graphics are the responsibility of the graphics driver. A web browser shouldn't dabble with those at all. Audio, you connect to PulseAudio (in Linux at least) and you're done. Hell I don't even care about ALSA or OSS here. You just connect to the stuff that does that job for you. And WebAssembly.. God I could rant about that shit all day. How about making it a native application? Not like actual Assembly is used for BIOS and low-level drivers. And that we already have a better language for the more portable stuff called C.

Seriously, think about it. Opera - a reputable browser vendor - managed to do it in 800kB on a 12 year old device. Don't go full wank on your framework shit on the comments. And don't you fucking dare to tell me that there's more to it. They did it for crying out loud. Now you take a look at your shitpile for JS code and refactor that shit already. Thank you.

imagine having kernel memory leaks in 2020

AT&T or Huawei, whichever, pushed an update for my already-struggling-to-exist phone that made the kernel memory leak go from 480KB/hr avg to 22.5MB/hr avg. When my free RAM is never under 50% of 2GB after the kernel starts loading other shit and i'm able to express free RAM, at any time in use, in megs, with 8 bits... this means my phone crashes, with no apps running aside from a trimmed list of stock apps, every 3-4 hours due to running out of RAM. The only usable (read: not R/O because unrooted) swapfile is located on a tmpfs, so it's completely fucking useless (and eats another 100MB of RAM that I could be using for LITERALLY anything else, that's like another 3 hours of full idle between crashes) and I can't unlock the bootloader to fix any of this as Huawei no longer hands out keys and it'd take 7 years or so to brute (32-bit @ 10/sec)

tl;dr: fuck

In 2010, it was my first client project. Our architect was not from iOS background, we had editable pdfs in our app. Those were pretty rich pdfs with inline HD images. iPads that time were not too fast and couldn't handle big gb pdf loaded into memory. App would crash randomly running out of memory. We fixed it by paginating pdf, it wasn't out of the world but considering it was my first mobile project and no one to guide, I thought it was pretty cool what we did there

Arguing with my girlfriend (recalled from my mind, not 100% accurate)

she: What do you expect when you buy an android?
Me: sure thing apple is more "unpack it, use it", easy to use - but android is more like an empty canvas. The first thing when I buy it is setting it up to my needs.
she: You don't understand, what do you expect from your android device?
me: It has to be affordable and work for a certain time
she: No I mean, do you.. when you unpack your phone, expect it TO WORK?
me: Sure, it's not like I buy a pile of trash, I expect it to work
she: you're too stupid, baka
me: ... ? *confused*
she: When you say it is like a canvas, isn't a canvas someday full?
me: yes, every phone, iPhone, Pixel, Samsung, every phone has a limited memory
she: *mad* you don't get it, silly
me: I want to but heh, I don't get it

PM: this is our super fancy new CI/CD pipeline, it's the greatest. i expect you to learn and understand all this in no time.
devs: so i have to spend some more time on this topic because it's completely new to me and requires some learning...
PM: nooo, that's a super easy task with zero effort, my braindead hamster can do that in no time, so can i, and so can you! let's assign 1 story point for that.

~ 3 months latèr ~

also PM, after he has started developing as well: so i'm realizing there are many things that i have to learn, and it takes me some time. i haven't developed with C++ and <other tool stack> for a longer time. by the way, you guys don't need to check for any quality right now, we need to deliver fast. it's okay, when you have memory overflows, your code is completely crappy, poor architecture or memory overflows, it doesn't matter.

he even has a subtask for migrating his code from VS project to our new project structure, since he refused to learn our pipeline right from the beginning and created VS project instead. シ why is this a subtask? this job can be done in no time, my left vanishing twin named Klaus who has dislexia and hates vim can solve this task in 20 seconds!!!!11

(and still no PR, not even a feature branch in our repo)

In college when we had programming labs where we had to use the schools unix server to compile and run.

My professor was very bad at explaining what actually needed to be done in the labs to the point where even the TAs didn't know what to do.

We were suppose to write an application in C to find out by "trial and error" how large we could make an array (or something like that, it's been too long). This not being explained well and no one knowing that much about C, I wrote a loop that just kept growing an array until it couldn't anymore. I watched it consume 72GB or memory from the servers before quitting the loop and realizing with the TA what the professor really meant.

I now feel bad for the IT staff monitoring the system wondering where 72GB just went...

I am not sure which 24 hours was the craziest one, but I will pick 2.

This one happened just a few weeks after I started working for the one and only company I have ever worked for. The huge-ass multi-tenant website stopped working. There was out of memory exception and nobody knew what is going on. I was still very new and knew shit about how it worked + plus my PHP knowledge was limited back then. Everyone was looking for the culprit but with no luck. Then the next day I finally managed to find a fucking infinite loop in our weather plugin.

We were working on a moderately big project for a client. There was a lot of work lately (on different projects) and we were *very* behind schedule on this one. Deadline? You guessed it - tomorrow. What was worse is that we couldnt move it any further, becuase we already did once before. So I had to work for about 20 hours straight to kinda finish the work. Worst part? Client turned out to be moron and half-scammer, so they are not our client anymore and the project was never deployed to production. Never again.

I feel so guilty.
I had to make a hotfix today. It is the ugliest piece of shit code I ever intentionally created. But there was no other way. I swear there was no other fucking way!

My boss just assigned this to me. But because she thinks this needs to be a hotfix and can't wait for the next release we just have to change the server and not the client side of our application.
So I had to add a memory to our server so that it knows from which high level method from the client the multiple low level calls to it are coming from.
It just doesn't make sense logically.

I mean I feel like I killed someone. And just so that we get less writes to our DB. I mean yes in some edge cases it is a huge speed-up...
But nothing this fix solves is a new bug.

I'm gonna take a shower now. For like an hour

Rant:
I am at work, some one says to me this system we are working on is multi threaded. I tell the no its not multi threaded and in this context. Things cannot happen concurrently. Its a single core arm 7tdmi. Arguments ensue abot the difference between multithread multitasking an multiprocessing. I proceed to explain this is a multitasking interrupt driven system. With no context switching or memory segmentation so one heap for all tasks cause thats how we have it configured and there is only one core. So there is no way the error he just described could possibly happen. Then he tells me im wrong but refuses to even look at the processor manual and rejects the Wikipedia entry for multithreading. So I plan on calling off so i can just have the next two weeks off while he trys to figure out why two things ar happening at once on this system. He deserves all the frustration that is to follow.

For the last week or so I've been writing a userbot for Telegram. Completely from scratch, plus Telethon to not reinvent the wheel entirely. I'm coming from the codebase of an existing userbot.

That userbot is written by a good friend of mine, who makes 6 figures, and whom I respect greatly. However the code is a steaming pile of shit. Now that is not his fault, he largely inherited that code too, tried to fix it, failed, gave up.

I am reimplementing it entirely. I'm only looking at the modules, trying to understand them, and copying over the necessary bits and changing them where necessary. But I've come across some nasty shit.

Userbots often edit existing messages from real Telegram clients. They're kind of like a login to your account, but with a program rather than a regular client. You send a message from a real client, it sees it and does whatever it needs to, and edits your message to give you feedback. Which is great.

However, there's no need to do simple string edits by importing "re". So why do you? Because you're an idiot, that's why. The old bot is based on Paperplane, which in turn is based on Telethon. Why do I see function calls to Telethon in some places and Paperplane in others? Because you're an idiot, that's why. Why does the dig module fail to even give correct answers? Because you know nothing about the DNS, that's why. And you didn't learn about RRs before implementing it.

And don't you tell me that this code is shit, and this bot is slow only when I run it on a fucking Pentium. I run this shit on an i7 and CPU isn't even the issue - memory, disk and such are. If you had any clue whatsoever about efficiency, you would've known because it's blatantly obvious. There's a reason why my machines rarely go past 5% CPU utilization. It's the fastest component in the entire fucking system.

When users come and say.. hmm this application of yours, it consumes a lot of memory. It takes a long time to do X and Y and I don't quite understand why, it seems illogical. Then maybe you should go look at your code, like you would look at yourself in the mirror. And then you fucking go fix it so that I don't have to. You're an engineer just like I am. And I am not even a dev proper - I'm a sysadmin by trade. Why should I have to fix your shit for you?

This is stupid but i think is my best idea yet.

So i have an old orange pi, with only 256m memory. Its running a few tasks i need but i wanted to use it for controlling a few things from my phone (lights and powering on my pc) so i thought i would make a server for that. Now mind you, my shirt doesnt say "lightweight backend language", so there was no way the pi couldve handled a struts server. I was digging around and found that php has a shell_exec command. Then it clicked, and i wrote the whole system like
shell_exec("java -jar someprocess.jar"). Now this sounds really stupid but it works and php is really light so it doesnt even slow it down that much.

Thinking about making this into some kinda server/framework/something just for fun.

Tried to figure out why my computer was being slow and lagging earlier. Thought it may have been a bad update to the kernel I recently did, or an update to a package.

No, it was chrome and its horrible memory usage.

Fucking hate my job 😡
I joined as nodejs dev at a mnc 3months ago involved in banking software in which i dont have any domain knowledge.. first 10 days I was told to go through fucking udemy nodejs and graphql tutorial (wtf) which i already have experience with before joining.. after that my reporting manager gives me task to resolve fields and gave me shitty jira story link to read.. that shit story link had no explanation about the fields and what the database it is, then she says to use some shitty sdk which is built internally by shiity devloper which had no documentation and have to follow other module which was again written by that sr. Dev... They hav fucked up the graphql and nodejs and entire stack and also till date no one has ever given any explanation about the domain and the fields and database schema.. this manager refuses to share knowledge about the domain now how the fuck i resolve the graphql schema which was again written by non technical b.a.. all they have used is latest technology in a shitty way with no standards to to follow .. no dataloading no caching no batching.. use shitty sdk which does not give access to dbconn and fucking tightly coupling expressjs which when i start consumes crazy 400Mb of memory .. these fucking seniors devs + the fucking b.a having 12+. Yrs exp each have fucked the entire codebase... Each day killing my passion for app development.. fuckkk ... Dunno what to do now

I'm convinced this is going to be wildly unpopular, but hey...

Please stop writing stuff in C! Aside from a few niche areas (performance-critical, embedded, legacy etc. workloads) there's really no reason to other than some fumbled reason about "having full control over the hardware" and "not trusting these modern frameworks." I get it, it's what we all grew up with being the de-facto standard, but times have moved on, and the number of massive memory leaks & security holes that keep coming to light in *popular*, well-tested software is a great reason why you shouldn't think you're smart enough to avoid all those issues by taking full control yourself.

Especially, if like most C developers I've come across, you also shun things like unit tests as "something the QA department should worry about" 😬

It grinds my gears to no end as to how insanely BAD most Electrical engineering software is. Lets start with Tina. A circuit simulator. A few versions ago it was rather good but now it feel like its built upon more legacy crap than fucking Windows! This causes it to have memory access violations and crashes even when you look at it from an odd angle.
On topic of circuit simulation. LT-Spice! It has less errors than Tina but is impossible to use without being lobotomized first. Who the FUCK decided it was a good idea to reinvent keyboard shortcuts by movin all of them to the F-row at the top of the keyboard. Also there is no option to delete a component. YOU NEED TO USE CUT IN ORDER TO REMOVE IT!
And at last Altium Designer for Layouting and Schematics. Whose license costs 9 grand. No one outside of some companies will buy this because of the price. Altium realized this and made two watered down versions of it. Which dont really get updates anymore. (last one was in 2018) So they essentially made a cash grab from people who cant afford their actual product. There also exist other (and a lot cheaper) products than what Altium offers. The problem is that they dont work well with interoperability. Schematics drawn in one program will look distorted in another or not import at all. And since Altium is the industry standard you got yourself this nice steaming soup of impossible collaboration. Its kinda like Adobe being absolute shit at progressing their software just because they got no competition. Or rather they do but the industry wont switch cause adobe is so engraved into it.

Imagine asking your friends to help you rate your app on the google play store and instead of saying NO I DONT WANT TO RATE YOUR APPLICATION no... they decide to fuck with your mind.

1)
I will rate it tomorrow. (she never rated it tomorrow nor the next couple of weeks later)

2)
I will keep it in mind and rate it later :). (she never rated it later)

3)
I rated it haha (less than 30 seconds later they deleted the rating)

4)
Send me a link and I'll rate it (i send the link, they never respond or read my message again)

5)
I dont have memory on my phone :) (because 13MB of memory is a lot of storage requirements but taking 1 million selfies of up to 25GB is completely fine)

6)
I dont have memory on my phone what dont you understand :) x2 (this is the second girl)

7)
Your trying to give me a virus?? No (i got blocked multiple times)

8)
You want to hack me by making me install this application from the link that you sent me that leads to google play store? No (blocked)

9)
Rate your app? Haha i dont care about it because it doesnt bring me any benefit only the fat cocks that fill my pussy up satisfy me and not ur app haha

10)
Haha send me a link ill rate it (i send link, 8 hours later no reply or reading my message, i text her back if she had done it and im still put on ignore)

...

N)

For all of you who are about to trash talk saying i am desperately trying to beg people to rate my app:

i know all of those people for a long time. But when it comes to asking (and not forcing) someone to do you a favor for free that takes no more than 30 seconds, no one seems to have 30 seconds of their free time. Dont get me wrong, some of my friends did politely rate it and left a review, even the people who i barely knew left a review and rated it, but the people with whom I was closer by, didnt.

---

In the beginning i used to not care about this at all. Then i started falling into depression because of it. I fell then into deep depression. Then i sunk so deep that i couldn't feel any emotions anymore so i laughed as an anti depressive mechanism whenever something depressing happened. Now i cant even laugh because i have no more energy. Now i actually leave man tears

---

The only thing more valuable than people, any materialistic thing, animals, coding and even money - is time....

----

why do you waste my time

if i ask you to do something that takes 30 seconds and you dont want to do it

why cant you just say no

why do you drag me

why do you say you're going to do it when you know you wont do it

what do you gain by unnecessarily lying to someone for such a small thing?

to someone who has been a good person to you?

do you feel superior?

is your ego bigger?

This experience has taught me that not even a human from the same blood can be trusted.

All of your are fucked up in the head in your own style and i am guilty of it too, all of us are.

But i have never seen the human evolution went from simplicity to overengineered complexitory bULLSHit where you have to lie to someone and waste hours, days, weeks, months and sometimes years of his time just because you dont want to say a 2 letter word, no.

But when that person becomes more successful than you and achieves higher status, Theen you have those 30 seconds of free time. All of you are fucking cynics. and i am so much overly disgusted by all of this fucking bullshit....

-----

This experience has proven to me to simply focus on investing into myself and learn and improve myself and no one else. To not even bother asking even for a small kind of help, a feedback from my work because people don't have 30 seconds of their free time. That is all.

So I was writing docs for my project the hard way. Manually. Every time I added something new, I had to find the right place for it to be alphabetically in the reference. And god forbid I want to have the same information in two pages: I would need to copy/ paste and pray that I not forget to update the information EVERYWHERE.

I didn't feel like installing and learning some new markdown generating bullshit so I just made my own system. It's very simple and intuitive and I love it.

I made sure it can cover two use case: reading partial documents from the disk, and rendering in-memory objects to markdown too (like rendering a collection of tuples into a table)

I didn't care much for templating, so there's no templating capability.

Many people here rant about the dependency hell (rightly so). I'm doing systems programming for quite some time now and it changed my view on what I consider a dependency.
When you build an application you usually have a system you target and some libraries you use that you consider dependencies.
So the system is basically also a dependency (which is abstracted away in the best case by a framework).
What many people forget are standard libraries and runtimes. Things like strlen, memcpy and so on are not available on many smaller systems but you can provide implementations of them easily. Things like malloc are much harder to provide. On some system there is no heap where you could dynamically allocate from so you have to add some static memory to your application and mimic malloc allocating chunks from this static memory. Sometimes you have a heap but you need to acquire the rights to use it first. malloc doesn't provide an interface for this. It just takes it. So you have to acquire the rights and bring them magically to malloc without the actual application code noticing. So even using only the C standard library or the POSIX API can be a hard to satisfy dependency on some systems. Things like the C++ standard library or the Go runtime are often completely unavailable or only rudimentary.
For those of you aiming to write highly portable embedded applications please keep in mind:
- anything except the bare language features is a dependency
- require small and highly abstracted interfaces, e.g. instead of malloc require a pointer and a size to be given to you application instead of your application taking it
- document your ABI well because that's what many people are porting against (and it makes it easier to interface with other languages)

porra; caralho; toma no cu.

this fucking shit xamarin. I wish the ass who programed the xamarin vs2017 integration to go fuck off.

srsly, I just want to fucking code this fucking fucker VS2017 keep shitting all around me

first I was gonna install it. didn't install because no memory left. fair enough, my fault there.

cleaned 35 gbs.

finish installing VS, with xamarin. FIRST GOD DAMN TIME I create fucking project, 2 fucking errors and 3 warnings. I DIDN'T EVEN TYPE A COMMA.

ok, tried fucking it. it seems to be conflict between version of Android and xamarin forms. fucker you it shouldn't be like this. anyway.

tried downloading the updated Android version.

it failed at 80%! what error you ask? missing fucking space ok, fuck that thing is huge, ok, my fault again. uninstalled all programs I was not using, all projects I'm not current working on. more fucking 30GB free. tried again. ANDROID IS TOO FUVKING HUGE CAN'T INSTALL IN 30GB!!!

Ok. instead of updating android, gonna downgrade xamarin, can't downgrade. ok gonna remove and install an early version.

unistalled. CAN'T FIND XAMARIN DLLS.

I was like, fuck this project, gonna start a new one. ok, all seems fine, for some weird reason. Except no. I try adding a new page, ops, APPARENTLY VS2017 CAN'T LOAD A GODDAMN .XAML

Ok, I can create a .cs page. done, except now I get a fucking timeout error. fuck.

I search the internet for a workaround, see a guy saying I could manually add a .xaml + .cs by creating this files and then adding them to the proj file.

did it. I go again, everything seems fine. but now I can't freaking reference the damn page.

I'm fucking losing my mind here.

In the mean time I have to turn in this project at the end of the week AND I CAN'T FUCKING OPEN THE GOD DAMN FREKING PROJECT PROPERLY!

FUCK. MY. LIFE.
FUCK XAMARIM AS WELL
FUCK VISUAL STUDIO
FUCK MICROSOFT
FUCK THAT DAMN SSD
FUCK THAT BOSS WHO THINK THAT A 128GB SSD IS ENOUGH
FUCK IT ALL...

I really think there should be a subject in every CS course to teach us how to handle/work-under Grade-A assholes and dumbfucks. Not that it would help, but atleast warn us on what we are getting into.

In my opinion, development is not *that* hard or frustrating but is made so by these shitty people. But again, what do I know.

I was scolded by my boss for using for-loop to iterate through an array recently. Apparently for-loop is not used in real world projects and this iteration should be done "in-memory". My colleagues and I are still trying to understand and process that.

I was asked to add fitbit integration to a project within 2 hours just because I had "already done it a week ago" in *another* project. Luckily, it was then given to a "senior" developer who took 4 days for it and essentially copy-pasted my work without much changes, ofcourse it stopped working every now and then.

I am given unreal deadlines on my tasks, on technologies I haven't worked on before, and then expected to churn out production ready code with no bugs in them.

My boss literally just sends me the links of 1st three google results on the problems I encounter and report, after humiliating me ofcourse. Yes, I did google it and yes I went through all I could find from Google forums to GitHub issues. When the library/plugin author himself says that this feature is not yet available, don't expect me to develop it in 2 hours you dumbfuck.

And for the love of God, please stop changing the data model every single day and justify it with agile development. Think before making any changes to it. Ever heard of Join queries? Foreign keys? Or any other basic database concepts.
We reached a point where each branch in the repo had different data model. Not kidding. And we were a team of just 4 developers. Atleast inform us when you change models after discussing it with your shit for knowledge "senior" developer, so we don't have to redo it all over again. The channels on slack are not for sharing random articles only.

I am just waiting to complete my year here.

I should have known what I got myself into the day he asked me to remove the comments I had added to explain what my code does. Why you ask? Because "we don't write comments".

Absolutely not dev-related.

Blah, blah, weird conversation and shit. I'm too tired and lazy to write this crap again, but let's do it.

The guy is a dev I randomly found on some chatting service, he was interesting to talk with until this conversation. I'll write this out of memory, so yeah.

Him: So by the way I wrote an app that you give your penis size to to get measurements and stuff about it.
Me, thinking it was dev humor: That's hilarious. Tell me more, I'm interested.
Him: So the idea behind all of this was to gather some big data style info about people's penis size and habits and all that stuff.
Me: Man that's awesome. Can I see the source?
Him: No, it's proprietary. You can buy a license though.
Me: You went that far for a joke?
Him: What joke?
Me: The whole software you just told me about.
Him: That's not a joke, I'm being very serious about it.
Me: Oh well. What did you get from the stats?
Him: I got some tips from people's habits! I never thought that shaving it could make it look bigger, but that's awesome!
Me: Do you really care about it that much?
Him: Studies have proven that size correlated with confidence. Since I started doing it, I've been more confident than ever!
Me: Great.
Him: I'm a bit disappointed to see that I'm in the lower percentiles though.
Me: Well of course you are.
Him: Why would you say that?
Me: Well since people with a big dick tend to go more willingly into the subject and might even buy a fucking app for it, of course you'd have the higher average in your stats.
Him: You're only saying that because you have a small cock.
Me: Why the fuck would you say that? You're the one that's concerned about it, not me.
Him: Go on, what's your size?
Me, because I don't care about discussing that stuff: *Tells him*
Him: [stats, comparisons and stuff]
Me: Well I never gave a fuck and your stats won't make me change my mind.
[ ... Some other shit about my size compared to his ... ]
Him: Would you want to work with me for the database maintenance?
Me: You must be joking?
Him: I'm serious.
Me: *Deletes account*

Seriously, fuck that guy. I rewrote that quickly so you only had the best, but it was a whole fucking conversation.

My two cent: Java is fucking terrible for computer science. Why the fuck would you teach somebody such a verbose language with so many unwritten rules?

If you really want your students to learn about computer, why not C? Java has no pointer, no passed by reference, no memory management, a lots of obscure classes structure and design pattern, this shit is garbage. The student will almost never has contact with the compiler, many don't even know of existence of a compiler.

Java is so enterprise focused and just fucked up for educating purpose. And I say it as somebody who (still) uses it as main language.

If you want your students to be productive and learn about software engineering, why not Python? Things are simple in Python can can be done way easier without students becoming code monkeys (assuming they don't use for each task a whole library). I mean java takes who god damn class and an explicitly declared entry point which is btw. fucking verbose to print something into the console.

Fuck Java.

I know I'm writing the correct integration tests when each one I add uncovers a new bug.

Still, it would be nice if just one of them passed first time.

My new favourite commit message:

"All changes as of 18th Sept"

How tremendously useful? There I was looking to know what changes were made to enable a feature / service, thought I could look for that in the commit message, but no you've given me a much more efficient way of finding out.

I simply need to download the contents of your memory, find out what date you made a change, and then dig through the massive commit to find the piece of info I need.

Forget experience using Git features, managing merges, following Git flow, or even any other SCM ... how can people be so tick when it comes to recording what they've done.

Heres a little cheat sheet for those struggling:

- Commit message
Describe what you actually ****ing did. Don't tell me the date or the time, thankfully Git records those. Don't tell me the day of the week, if I need to know I can figure that out, just tell me what ... you ... did.

- Feature branch names
Now this is a tricky one. You might be surprised to know that this isn't in fact suppose to be whatever random adjective or noun popped into your head ... I know, I too was shocked. The purpose of this is to let other people know what new feature is being worked on in this branch.

- Reusing feature branches
Now I know you started it to add some unit tests, and naming it "testing" is sort of ok. But its actually not ok to name it testing when you add 3 unit tests ... then rip out and replace 60% of the business logic. Perhaps it would have been wiser to create a new feature branch, given you are now working on a new feature.

A friend came to me whether i want to do a project on c++(someone asked him to find a c++ guy).
Me needing money didn’t refuse. Even though i am a Java developer with 0 skills on c++, but wanted to give it a try.
So project started, and it was about a plugin for rhinoceros app(3d graphics app).
The plugin was simple, had some views and some services to upload a file into s3 and some api calls, not something complex..
So i ended up working on the project together with my friend(web dev).
So long story short, we had a lot of issues, but considering we both had no knowledge on c++, we were really lucky to finish the product almost on time(3 days after).
Did no memory management even though i’ve read that we have to do that by our selfs and that c++ doesn’t have garbage collector.
But the plugin worked great even without garbage collector.
Had a lot issues with string manipulation, which almost drive me crazy.

PS: did a post here before taking the project, to ask whether it is a good idea to take the project or not, had some positive and some negative replies, but i deleted the post since i thought i was breaking the NDA i signed 😂😂

PS2: just finished OCAJP 8 last week with a great score😃

So, I work in a game development studio, right?
We're trying to launch the title on as many platforms as reasonable, because as a social VR app we're kinda rowing upstream.
So far, Steam and Oculus have been fairly reasonable, if oddly broken and inconsistent.
Enter store 3.
Basically no in-game transaction support (our asking prompted them to *start* developing it. No, it's not very complete). No patch-update system (You want an update? Gotta download the whole fsckin' thing!). No beta-testing functionality for most of their stuff ("Just write the code like the example, it will work, trust us!"). No tools besides the buggy SDK (Wanna upload that new build? Say hello to this page in your web browser!).
So, in other words: Fun.

We've been trying to get actively launched for two months now. Keep in mind that the build has been up on Steam and Oculus for over a year and half a year (respectively), so the actual binary functionality is, presumably fine.

The best feedback we get back tends to be "Well, when we click the Launch button it crashes, so fail."
Meanwhile we're going back and forth, dealing with other-side-of-the-world timezone lag, trying to figure out what is so different from their machines as ours. Eventually we get them to start sending logs (and no, Windows Event logs are not sufficient for GAMES, where did you even get that idea????) except the logs indicate that the program is getting killed so terribly that the engine's built-in crash handler can't even kick in to generate memory dumps or even know it died.

All this boils down to today, where I get a screenshot of their latest attempt.

I just can't even right now.

I found this on a wiki with Haskell Humor... it's interesting...

How to Shoot Your Self in the Foot With Haskell: Putting the unsafe in unsafePerformIO!

You shoot the gun, but the bullet gets trapped in the IO monad.
Couldn't match expected type 'Deer' against inferred type 'Foot'.
While compiling your program the compiler produces a type error long enough to overflow a kernel buffer, overwrite the trigger control register and shoot you in the foot.
After trying to decipher the type errors from the compiler, your head explodes.
After you've finally found a way to circumvent the type system and shoot yourself in the foot, Oleg appears out of nothing and shoots you in the foot for coming up with it before him.
You shoot the gun but nothing happens (Haskell is pure, after all).
Your foot is fine, until you try to walk on it, at which point it becomes mangled.
You have a shootFoot function which you've proven correct. QuickCheck validates it for arbitrary you-like values. It will be evaluated only when you end up at the hospital. You hope this doesn't come to pass, as it actually returns a bullet-ridden copy of yourself and you don't want to be garbage-collected.
foreign import ccall "shootparts.h shootfoot" shoot_foot :: Gun -> Programmer -> IO ()
shootSelfInFoot = unsafePerformIO . shoot . foot $ self -- Shoot self in foot 0 or more times depending on evaluation order
No instance for (Target Foot)
arising from use of `shoot' at SelfInflictedInjury.hs:1:0
Possible fix: add an instance declaration for (Target Foot)
In the expression: shoot foot
You go to shoot yourself in the foot but the bullet is in the ST monad and the gun is in the IO monad, so you can't.
You ask Haskell to shoot you in the foot but by the rules of lazy evaluation you don't need the result yet so it doesn't happen.
You decide to shoot yourself in the foot but get distracted devising a ballistics algebra and wondering if you can do the calculations in the type system.
You want to shoot yourself in the foot but realize there is no Gun datatype so use Arrows instead.
You shoot in the direction of your foot, but since you are inside the STM monad you can just retry until you figure out what to do.
You shoot yourself in the foot, but you are perfectly fine as long you just don't evaluate the foot.
You shoot yourself in the foot, but nothing happens unless you start walking.
Don't forget about memory consumption! If you don't look, the bullet causes heap overflow. If you look, the bullet causes stack overflow.
You *appear* to have deliberately shot yourself in the foot, and yet your program actually runs perfectly OK due to lazy evaluation. (So long as you remember to not look at your foot...)
You aim the gun at your foot, pull the trigger and remove the clip. When you look at your undamaged foot, the hammer clicks on an empty barrel.

I like developing on windows. Like many people here I got into development at home starting as a hobby when I was in school so there were things I still did on my computer that Linux wasn't really appropriate for.

I've made the jump to Linux in the past but found that it was awkward and annoying when I needed to do something on my windows. And I hate doing Dev out of a VM. So I've just got used to using windows at home.

And honestly, I don't know what's happening to everyone who keeps getting broken Windows updates. I think I've had 2 in living memory.

It's in no way perfect but what is? I don't use Windows servers, just for when I'm at home.

The process of making my paging MIDI player has ground to a halt IMMEDIATELY:

Format 1 MIDIs.

There are 3 MIDI types: Format 0, 1, and 2.

Format 0 is two chunks long. One track chunk and the header chunk. Can be played with literally one chunk_load() call in my player.

Format 2 is (n+1) chunks long, with n being defined in the header chunk (which makes up the +1.) Can be played with one chunk_load() call per chunk in my player.

Format 1... is (n+1) chunks long, same as Format 2, but instead of being played one chunk at a time in sequence, it requires you play all chunks

AT THE SAME FUCKING TIME.

65534 maximum chunks (first track chunk is global tempo events and has no notes), maximum notes per chunk of ((FFFFFFFFh byte max chunk data area length)/3 = 1,431,655,763d)/2 (as Note On and Note Off have to be done for every note for it to be a valid note, and each eats 3 bytes) = 715,827,881 notes (truncated from 715,827,881.5), 715,827,881 * 65534 (max number of tracks with notes) = a grand total of 46,911,064,353,454 absolute maximum notes. At 6 bytes per (valid) note, disregarding track headers and footers, that's 281,466,386,120,724 bytes of memory at absolute minimum, or 255.992 TERABYTES of note data alone.

All potentially having to be played

ALL

AT

ONCE.

This wouldn't be so bad I thought at the start... I wasn't planning on supporting them.

Except...

>= 90% of MIDIs are Format 1.

Yup. The one format seemingly deliberately built not to be paged of the three is BY FAR the most common, even in cases where Format 0 would be a better fit.

Guess this is why no other player pages out MIDIs: the files are most commonly built specifically to disallow it.

Format 1 and 2 differ in the following way: Format 1's chunks all have to hit the piano keys, so to speak, all at once. Format 2's chunks hit one-by-one, even though it can have the same staggering number of notes as Format 1. One is built for short, detailed MIDIs, one for long, sparse ones.

No one seems to be making long ones.

Learning Rust.

Holy brainfucking brain melt, those references, scoping and borrowing and cloning and whatnot, because there is no garbage collector, but also no direct memory management.

It's cool, but also hard for a noob coming from the JVM/Android. The compiler error messages are helpful, but I immediately found some cryptic ones that don't help me at all.

it was not a technical interview.
just screening.

guy: tell me smth about redis.

me: key value, in memory storage.

guy: more

me: umm, the concept is similar to localStorage in browsers, key value storage, kinda in memory.

guy: so we use redis in browsers?

me: no, I mean the high level concept is similar.

guy: (internally: stupid, fail).

Man wk89 awesome... bringing back a lot of memories. The one thing really stands out to me though is the software.

I see a lot of rants about people shocked that turboC is still in use or other DOS programs are still in production. A lot can of bad be said here but I think often it's a case of we truly don't build things like we did in the good old days.

What those devs accomplished with such limited resources is phenomenal and the fact that we still haven't managed to replicate the feel and usability of it says a lot, not to mention just how fucking stable most of it was.

My favourite games are all DOS based, my most favourite of all time Sherlock is 103kb in size. When I started coding games I made a clone of it and to this day I am still trying to figure out what sorcery is in the algorithm that generates/solves puzzles that makes it so fast and memory efficient. I must have tried 100+ ways and can't even come close. NB! If you know you can hint but don't tell me. Solving this is a matter of personal pride.

Where those games really stand out is when you get into the graphics processing - the solutions they came up with to render sprites, maps and trick your eyes into seeing detail with only 4-16 colours is nothing short of genius. Also take a second to consider that taking a screen shot of the game is larger than the entire game itself and let that sink in...

I think the dramatic increase in storage, processing power and ram over the last decade is making us shit developers - all of us. Just take one look at chrome, skype or anything else mainline really and it's easy to see we no longer give a rats ass about memory anywhere except our monthly AWS/GCE bill.

We don't have to be creative or even mindful about anything but the most significant memory leaks in order to get our software to run now days. We also don't have constraints to distribute it, fast deliver-ability is rewarded over quality software. It's only expected to stay in production 3-4 years anyway.

Those guys were the true "rockstars" and "ninja" developers and if you can't acknowledge that you can take ya React app and shovit.

Not sure how to handle this one. My new company gave me a surface laptop to do dev ops work.

16 gigs of Ram but only a 256 SSD?

Nothing is installed so far except for MS office and acrobat and I am already running into memory issues.

My last work machine had 1TB HDD and 128 gigs of RAM (i know overkill but I could have several VM’s up and running at once).

What the fuck? Apparently the CTO ordered this piece of shit.

Also no mirco SD card like other models so I have no idea how this is going to fucking work.

Most memorable co-worker was a daft idiot.
this was 10 years ago - I was working as a junior in my very first job, fresh out of uni, for a very small startup. It was me, and the 3 founders, for a very long time. Then this old (45, from my perspective then..) dev was hired.
This guy had no idea how to do the job. no common sense. the code confused him. the founders confused him. I was focusing on my work - and was unable to help him much with his. His only saving grace? He was a nice guy. Really nice.
But why was he so memorable, out of all the people I ever worked with? simple. He had a short term memory problem. Could not, even if he really tried, remember what he did yesterday.... when I asked him what his issue was, he decribed his life is like a car going in reverse in a heavy fog. "I can only see a short distance backwards, with no idea where I'm going".

Startup was sold to a big company. I became a teamlead/architect. He? someone decided he should be a PM.

Fucking hate Qt.

Spent all morning trying to figure out how their bullshit QThreadPool works with their bullshit QRunnable but after a bunch of bullshit asynchronous testing I figured that my thread object was being collected and deleted before I was done with it, for no reason. Now if the race condition was documented... This wouldn't be an issue. But every google search brought up nada. Eventually I resorted to turning off autoDelete on the runnable, but then I just have a memory leak, obviously.

I couldn't find a way to manually clean up a QRunnable in Python. What the fuck.

I just went back to good old fashioned QThreads... This is why I quit Qt in the first place.

Imagine you work in a mechanic’s shop. You just got trained today on a new part install, including all the task-specific tools it takes to install it.

Some are standard tools, like a screwdriver, that most people know how to use. Others are complicated, single-purpose tools that only work to install this one part.

It takes you a couple of hours compared to other techs who learned quicker than you and can do it in 20 minutes. You go to bed that night thinking “I’ve got this. I’ll remember how this works tomorrow and I’ll be twice as fast tomorrow as I was today.”

The next morning, you wake up retaining a working, useful memory of only about 5% on how to use the specialized tools and installation of the part.

You retrain that day as a review, but your install time still suffers in comparison. You again feel confident by the end of the day that you understand and go to bed thinking you’ll at least get within 10-20 minutes of the faster techs in your install.

The next morning, you wake up retaining a working, useful memory of only 10% on how to use the specialized tools.

Repeat until you reach 100% mastery and match the other techs in speed and efficiency.

Oops! Scratch that! We are no longer using those tools or that part. We’re switching to this other thing that somehow everyone already knows or understands quickly. Start over.

This has been my entire development career. I’m so tired.

We had 1 Android app to be developed for charity org for data collection for ground water level increase competition among villages.

Initial scope was very small & feasible. Around 10 forms with 3-4 fields in each to be developed in 2 months (1 for dev, 1 for testing). There was a prod version which had similar forms with no validations etc.

We had received prod source, which was total junk. No KT was given.

In existing source, spelling mistakes were there in the era of spell/grammar checking tools.

There were rural names of classes, variables in regional language in English letters & that regional language is somewhat known to some developers but even they don't know those rural names' meanings. This costed us at great length in visualizing data flow between entities. Even Google translate wasn't reliable for this language due to low Internet penetration in that language region.

OOP wasn't followed, so at 10 places exact same code exists. If error or bug needed to be fixed it had to be fixed at all those 10 places.

No foreign key relationships was there in database while actually there were logical relations among different entites.

No created, updated timestamps in records at app side to have audit trail.

Small part of that existing source was quite good with Fragments, MVP etc. while other part was ancient Activities with business logic.

We have to support Android 4.0 to 9.0 of many screen sizes & resolutions without any target devices issued to us by the client.

Then Corona lockdown happened & during that suddenly client side professionals became over efficient.

Client started adding requirements like very complex validation which has inter-entity dependencies. Then they started filing bugs from prod version on us.

Let's come to the developers' expertise,
2 developers with 8+ years of experience & they're not knowing how to resolve conflicts in git merge which were created by them only due to not following git best practice for coding like only appending new implementation in existing classes for easy auto merge etc.

They are thinking like handling click events is called development.

They don't want to think about OOP, well structured code. They don't want to re-use code mostly & when they copy paste, they think it's called re-use.

They wanted to follow old school Java development in memory scarce Android app life cycle in end user phone. They don't understand memory leaks, even though it's pin pointed by memory leak detection tools (Leak canary etc.).

Now 3.5 months are over, that competition was called off for this year due to Corona & development is still ongoing.

We are nowhere close to completion even for initial internal QA round.

On top of this, nothing is billable so it's like financial suicide.

Remember whatever said here is only 10% of what is faced.

- An Engineering lead in a half billion dollar company.

Debugged a complex bug at 10 PM, drunk and eating potato wedges, while on the phone with another drunk co worker.

Woke up next morning and had no memory of the fix.

I just got a new phone, a Tecno device with a measly 8GB internal storage. Decided I'll have to root it, and force part of my class 10, 32GB mem card as adopted storage.

Went online, learnt for a few weeks, successfully rooted, and began enjoying the vast benefits.

But there are no good endings. Months later, while doing some heavy gaming, my phone reboots... and everything on the memory, pack up and go on a vacation...

The best QA in the world is your boss. He always jump in and ask you to show him something that is not completed yet. He then acts like a professional and points out the red is not red enough... You have no word, mark down all the design changes, pass a message to designer, and then, finally, You forgot what's going on in your mind!!! And it takes another hour for you to resume your memory back....

I have a friend that keeps his phone on "Battery saver" all the time... It's painful to always see that notification with "your phone is on battery saver mode".
He told me he does that because he does not want his battery to empty too soon...
A while ago he refused to use my Micro USB cable because he told me there might be viruses on that cable. ON THE CABLE!!!! Like viruses stored inside a cable that has no memory... A simple cable ( da fcuk? )

The worst part? He's studying computer science :/

Anyone else have people that seem to constantly try to "prove" themselves to you in this weird, competitive way that only makes them seem... very annoying? I'll call him Bob here, but it's always something like:

Bob: Hi Almond, how's it going?
Almond: Ah not bad thanks, PSU blew up in the PC over the weekend though so that was a bit of a faff!
Bob: Ah no! How old's your PC?
Almond: Oh, like 7-8 years old now. I don't replace it often.
Bob: Really?! I replace mine completely every year.
Almond: Ah, cool.
Bob: Yeah, I'm a dev so I feel I need to. It's like my tool, you know.
Almond: Sure thing!
Bob: I actually spend quite a lot on it. I make sure it's got the fastest memory I can afford. Like, DDR5 stuff. That's really important, you know.

...etc., while I try to get out of said conversation for the next eternity.

Or:

(while in a conversation about a frontend bug I was looking at in Chrome devtools)
Bob: Hey Almond, you know Firefox actually had a plugin that did all this stuff before everything else?
Almond: Err, yeah, I think so. Used it back in the day.
Bob: It was called firebug. It was really good. Revolutionary.
Almond: Certainly was.
Bob: It was launched in January 2006 you know.
Almond: Right...
Bob: I used it back then.

...I mean damn, I'm all for being civil, but no-one cares you replace your PC every year, or that you know the year firebug was released, or that you once set up 5 identical PCs with different versions of Linux to run some benchmarks...

One of the biggest challenges for me learning to program is my memory.

Some people can pick up concepts easily and have a field day. I have to keep practicing until I memorize it properly, and even then I have the tendency to struggle.

Does this mean I give up? Helllll no. I'm far from giving up with all the progress I've made.

Was playing fallout 4 a couple days ago. About 20 minutes in. The computer just shuts off. Like no power at all. I start up the computer again. Try fallout 4 again. It shuts off at the beginning video. WTF... I try Skyrim wondering if video card is busted. Skyrim runs perfectly fine. I startup Fallout 4 again. It runs. WTF...

Next day I try fallout and bout 20 minutes in power off again. Now I am assuming cooling issue and I am trying to see temps with programs. Cannot really tell.

So today I take apart my laptop and vacuum every cooling orifice out. Vacuum any dust looking crap I can see. There was dust in the fans. All clean. I run a memory test for a couple hours. Memory passes (it was brand new memory, thought maybe flaw in ram). Now I run fallout 4. Runs fine, zero issues for about an hour.

Me to myself: CLEAN YOUR DAMN COMPUTER MORE OFTEN! Okay...

In between I read about Fallout 4 causing system reboots and shutdowns due to loading and heating. Apparently something about Fallout 4 causes this more than other games. Wild... Pretty sure it was thermal shutdown protection going on.

I usually crib about how stupid people are and how I struggle to stay afloat.

Let's switch some gears now. A post about some good people, product, and processes.

You know what the common theme here is?

The goodness here cannot be measured. Your first interaction with them makes you feel so comfortable that you start feeling butterflies.

These people just keep on giving. They are selfless. They are pure. They actually care.

And when you think it's done, then they give you some more.

What blows me away is, they don't expect or accept anything in return. Absolutely nothing. Not even a simple thank you.

And they are like a wizard. They walk into your life when you least expect them but need them the most. And when the task is done, they'll be gone before you even know.

No lingering, no drama, no bullshit. Just pure goodness.

Like my ex-lead in current company, I have a very senior guy in neighbouring team (for which they were gonna hire me initially), who also happened to interview me, is a gem.

He takes care of me like his own younger brother. Supports me and always answers my queries no matter how occupied he is.

And same is with good products and processes. They feel effortless. So smooth and add exceptional value to your existence. They give rise to wonderful companies.

You'd never experience a single negative aspect about them. No matter how much you try, things will just keep getting better until they don't need to.

And then they'll be long gone. Never to be seen again and never to be forgotten.

You cherish them only in your memory and wish they lasted longer. But they didn't because the purpose was served.

Such people and experiences inspire me. They push me to become a better human.

No matter how the world is or how it treats me, I must always live with high values and be a better version of past self.

The other evening, I was conversing with my mother where we spoke about some family friends who are insanely wealthy but humble and kind.

Mom and I mutually agreed that they don't have such good traits because they are wealthy, but they are wealthy because they live with humility, kindness, and pure intentions.

World is surely a beautiful place because of such people and I aspire to be one. May lord guide me well :)

Avoid ACPICA if at all possible. It's one garbage tier cluster fuck of bad design, horrible documentation and downright misleading and wrong code

It's meant to consist of an ASL compiler, disassembler, debugger, dumper, various user space utitilies and a kernel resident OSPM implementation *if* you can figure out what belongs to what. Even just compiling this pile of trash is a mystery in itself. Think you need the source files in source/common? EEEEH, wrong. Well, at least partially since most of them seem to be for the user space stuff..? Other ones *are* needed on the other hand. At least the disassembler and/or debugger and/or dumper components seem to reference them. Not that I could figure out how to compile those anyways. The real path to your goal seems to be to ignore a seemingly arbitrary subset of source and header files until your linker stops complaining

There's also a bunch of configuration defines, some of which *you* define, some defined *for* you, based on again others. Of course most of them do stupid shit. Enabling the debugger automatically enables debug logging. Enabling the disassembler force enables debug allocation tracking... What?

The code itself isn't of much help either. Looking in "os_specific/service_layers" you find what looks to be reference implementations of acpica functions in certain os' like windows and unix. Of course I had a look because AcpiOsReadMemory is supposed to read physical memory and I don't know how I would even implement that. But hey, osunixxf.c (xf for interface... of course) should tell me. I'll let you see for yourself in the attached image. Apparently it does fuck all and just returns AE_OK. No error, no logging, no nothing. Just ok. As you can imagine, AcpiOsWriteMemory doesn't do much more either.
...okay so maybe physical memory accesses aren't actually used and these functions are some sort of relic from past times? Nope! They are absolutely necessary for doing low level device interaction. WTF. So finally I went to the linux source and checked how *they* implemented them, and just as I thought, these functions are anything but no-ops...
...So for what fucking reason do these stupid interface implementations even exist but to purposefully mislead you?? They aren't used for fucking anything! As far as I know Windows doesn't even *use* ACPICA and Linux have their own fork with working implementations... They just sit there, just to tell you how to NOT do it

So that's some of my thoughts about ACPICA. Note that I haven't even used it as a library yet, I just got it to compile and link and it already fucked with me this much.
There's also so much more I didn't mention like that you *have* to modify the acpica source in order to get your own platform header working (else #error) eventhough the docs explicitely instruct you not too but you get the point

Don't use ACPICA if you don't have to. Save your sanity for something that's worth it

I'm getting beat up pretty bad by Rust. I like it so far but man is it hard. Imposter-syndrome is almost making me lose motivation. Almost, but I won't quit, one day I'll get there.

I think the primary reason I think I'm having such a hard time is that I'm trying to learn stuff that prevents me from making some mistakes that I have never run into. I know a bit of the theory but no hand's on experience on double-free errors, memory leaks and weird low-level stuff. I read the documentation, mostly understand what stuff is for but when I go write code I'm just like "now what?". I don't have enough experience to know when and where to use some concepts and I'm super lost. I don't know where to start and the feeling of being completely overwhelmed by all sorts of new stuff is at the same time exciting and frightening.

I have never, as a programmer, thought something was hard. All of my past knowledge required dedication, work and patience, but I wouldn't say I ever felt something was *hard*. But Rust... damn. Rust is hard.

Hopefully at the end of this super steep learning curve I'll know a lot more stuff and have stronger "dev powers" and be one step closer to being as knowledgeable as some of you guys around here to whom I look up to.

I'm rewriting a game from C++ to C just for the purpose of learning and adding more features, however; after I refactored the code, the game broke with a segmentation fault and I have no idea where the memory issue is.

I've been debugging for hours now and I've got nothing. FML

Pretty much a sort of research work. The first assignment was: "look, we have this CAD viewer, but we would want to eventually optimize the structure of the mesh, so here's this method of minimizing the memory footprint. Try implementing it and integrating it with our application."

PS: the method is using triangle strips, where the next triangle uses two vertexes of the previous one, theoretically reducing the memory footprint of the mesh by 2/3 if the mesh is fully optimized. In the end, due to memory and performance constraints (this had to run on the first gen iPad), and overall application architecture, on the fly striping was unfeasible and gained no benefit, because striping an arbitrary mesh is a fucking hard task.

Another one was an implementation of smooth shading by recalculating vertex normals in runtime.

Fellow Deviants, I need your help in understanding the importance of C++

Okay, I need to clarify a few things:

I am not a beginner or a newbie who has just entered this community...

I have been using C++ for some time and in fact, it was the language which introduced me to the world of programming... Before, I switched to Java, since I found it much better for application development...

I already know about the obvious arguments given in favour of C/C++ like how it is a much more faster and memory efficient than other languages...

But, at the same time, C/C++ exposes us and doesn't protect us from ourselves.. I hope that you understand what I mean to say..

And, I guess that it is a fair tradeoff for the kind of power and control that these languages (C/C++) provide us..

And, I also agree with the fact that it is an language that ideally suits our need, if we wish to deal with compilers, graphics, OS, etc, in the future...

But, what I really want to ask here is:

In this age and times, when hardware has advanced so much, where technically, memory efficiency or execution speeds no longer is the topmost priority... These were the reasons for which C/C++ was initially created...

In today's time, human concept of time matters more and hence, syntactical less complicated languages like Java or Python are much more preferred, especially for domains like application development or data sciences...

So, is continuing with C++, an endeavour worth sticking with in the future or is it not required...

I am talking about this issue since I am in a dilemma about the use of C++ in the future...

I would be grateful if we could talk about keeping AI, Machine Learning or Algorithms Optimisation in mind... Since, these are the fields in which I am interested in...

I know that my question could have been posted in a better way.. But, considering the chaos that is present in my mind, regarding this question doesn't allow me to do so...

Any kind of suggestion or thoughts would be welcome and much appreciated...

P.S: I currently use C++ only for competitive programming or challenges...

"Suggest an AV/AM product, Avast refuses to install."

I do malware research as a hobby and have for a while, so I can generally spot when something's up before I even run a program. If i'm unsure about it (or know something's up and wanna see its effects for S&Gs) I throw it into one of a variety of VMs, each with a prepped, clean, standardized "testing" state.

I see no point to AV/AM products, especially as they annoy me more than anything since they can't be told not to reach into and protect VMs (thereby dirtying up my VM state, my research, crashing the VM hypervisor and generally being *really* annoying) and they like to erase samples from a *read-only, MOUNTED* VHDX.

However, normal people need them, so I usually suggest this list:
• MBAM is good and has a (relatively) low memory footprint, but doesn't have free realtime protection.
• Avast is very good as it picks up a lot, but it eats a FUCKTON of resources. It also *really* likes to crash VM hypervisors if it sees anything odd in them.
• AVG is garbage. Kill it with fire.
• Using Windows Defender is like trying to block the rain with an umbrella made of 1-ply toilet paper.
• herdProtect is amazing as it's basically a VirusTotal client but it's web-based and not currently available to be downloaded. (Existing copies still work!)
• Kaspersky. Yes, it spied on US gov't workers. No, they don't care about anyone BUT US gov't workers. Yes, it's pretty good.
• BitDefender: *sees steam game* "Is this ransomware?"

hope this helps

So another story about college and stupid team assignments that I have to be responsible for dealing with.

So we had an assignment in operating systems 1 course, it was about memory management and we are a team of 3. Then came the time when we should discuss this assignment with the TA and that day I had to stay all night finishing a project in software engineering (literally giving us a description of a big project because that's what the course teaches And I had to finish it in one all nighter alone because my teammates just gave up).

When the discussion time came I was really tired and then the TA asks me something really simple and I say it but then she tells me that I'm wrong so I wondered a bit and then said no what I said was right! She then asks my teammate (who we are supposed to be good friends) "did he say the right thing?" And his answer is a definitive "NO he's wrong" and then he starts to say the right answer which I swear I said the same but in a different way so I start to say again that I was right and say that I said that just a different way and she took that as an insult and said that I'm shouting at her and being disrespectful to her.

When we finished I asked my friend if he heard me say it wrong and he said "I'm sorry but I didn't even hear what you said and I was afraid" WHAT THE FUCK, he just said that I was wrong to please her and make her feel like she is right and I had to be the wrong one even though I said it right but NOoo her pride is more important

All this was last semester and the second semester just started today and I go into operating system 2 and guess what? The TA got her doctorate and is now the professor for OS 2 when she doesn't even understand anything.

Really FUCK the academic system it feels like it is a grind more than actually gaining mastery of a subject.

fuck oracle. fuck my company.

Using Oracle VM Manager/Servers to host Oracle Phone transfer solution without support coverage from Oracle.

Requiring Unix sysadmins to update to latest release and not telling that we do not have coverage from Oracle if anything goes wrong.

Gues what.. We've updated to Oracle VM Manager/Server 3.4.5 which was released this year and it uses fucking XEN hypervisor version 4.4.4 which has been deprecated and dead since who knows when. Latest release of XEN is 4.11. But that is not an issue, whatever, enterprise, legacy software, etc.

This fucking update introduced memory leak on the hypervisor which has been reported as per xen 4.4.4 history. Furthermore, we have no support from Oracle which means that I have to dig through mailing lists and limited information on the net since oracle has freakin support wall on nearly each of the major bugs found on that shitty software.

I have no idea whether any newer version of xen will work with that old Oracle Linux kernel or not.

Furthermore, Oracle provided great documentation on how to rollback the fcking update. Reinstall the hypervisor. Riiiight. XEN does not have export/import feature.

eh

Oh my god I forgot to add swap to my install. No wonder I'm having memory issues 😅

Mozilla really knows how to nudge one to not use email encryption by default.
Since Thunderbird has native support for OpenPGP encryption, i can only chose to encrypt all or no messages by default. There is no opportunistic mode and there are no per-reciepient encryption preferences. The Enigmail addon had both.
So i obviously have gone for encrypt-by-default.

But since then, whenever i want to send a message to the majority of my contacts, i have to manually disable the encryption or get annoyed by the no-key-found dialog.
I thought, i would get the muscle memory to just disable encryption for recipients for wich i don't expect to have a key.
But they also made the GUI so i have to open a dropdown and then click on the right item to do that. All the items basically look the same, as there is no color coding or specific icon for them. The item labels are also too long for unconscious pattern recognition.
So i didn't got that muscle memory.

I now have turned off encryption by default and will probably forget to enable it for some emails wich i actually could send encrypted...

Have been playing the pirated version of Rust for 30+ hours with no issues.

Decide to buy the game and every fucking time the game turns into Chrome and consumes all my RAM forcing Windows to show the low on memory dialog.

Lesson learned I guess.

So we’ve taken over from a project team that disbanded... read: “cut their contracts because fuck this, I can earn more working for better people”.

Me and one other guy have been tasked with saving this heap of shit.

Obviously the project guys left saying “it’s nearly done, just this one feature”. Because cut contracts are easier to deal with if “everything is almost done”.

We jump on and find that’s not the case at all... this thing, is a beast, a big old stats analysis program... so we’re like “cool, let’s see what’s going o...OH MY GOD”.

The “recalculation” function was core to this POS. The contractors had done it in C# through entity framework... it took 24 hours to run, over a reasonably small data set that was due to double every 2-5 years.

So... here’s the deal, it ran over night.... then failed. And no cunt had noticed. Entity framework “can’t commit because I’m muddled up as fuck, did you really just put the whole db in EF in memory to work with it?” Exception.

Que 6 months of me and my lead doing the job properly.

Anyway, the failure: I ended up in Hospital again with a Crohn’s flare up... about 5 months in.

Fuckall to do with all this nonsense I just wanted to tell a story. it was an interesting/fun project to fix and my lead was a legend... so happy days.

Similar story, different set of contracted devs... they’d been defining requirements with the business users using the term “Risk” which the business users knew as a group of risks.

The domain model had been written RiskGroup<>—

GOD DAMN IT COLLEGE YOU DID IT AGAIN. for real college can go suck Satan's 50 inch red cock for all I care.
A professor asked me to design a processor and I'll get a bonus. I said okay cool nothing hard.
oh but it has to be in verilog.
okay cool.
oh and it has to be on this fucking ancient useless piece of shit called xilinx that the fucking college provides to you only via a fucking 50 gigabyte virtual machine.

sigh. okay..... challenge accepted.

It fucking crashes every 2 minuites. And after 3 days of no sleep. I finally finished the Alu, Control unit, 4k memory, 8 registers and the busses.......... BUT THEN THE ENTIRE VIRTUAL MACHINE CRASHED AND LOST ALL PROGRESS...... fml.
and the professor only gave me the bonus for the Alu. sigh. fuck college.

today my cpu was at 100% (red) ram at 96% (above 95 is memory leak) and disk 95% (almost no space left) bc i ran emulator 2 android studio projects chrome etc all in the same time

Reanimated an old e-ink tablet today.

First, I didn't even know it needed to be reanimated. I just copied my books there, but it didn't find them. When I connected it again, they were gone.
Factory reset. Format storage. The memory seems empty, but after rebooting I see that everything is still intact.
Ok, imma hit forums then. They tell me I need to replace the internal memory. But isn't that something you need soldering for? Wrong! The internal memory IS JUST A MICRO SD CARD on the motherboard. The card is some cheap no name one, and people tell the similar story of it burning out after like four years of use.
Damn! The vendor has the AUDACITY to charge for signing their firmware to be flashed to a new micro sd card.

But I won't go down this easily. I hit forums again, and apparently there is a tool to sign the firmware yourself, but you need to find the card's serial number. To do that, you have to flash a bootleg tool, boot from that card, and it will show you the data you need. Then, you have to insert them into some shady .ini file (why is everything touching bootleg firmware runs only on windows?).

So I do that. The problem is, I need an image for my book. I find some shady one online, sign & flash it — touchscreen doesn't work. But I have the official firmware. I put two and two together and figure out that if the reader is able to display the ui, it probably has the firmware update tool working. So, immediately after flashing, I launch the firmware update utility that picks up my firmware from the second sd card (yes, they have an additional external slot).

Bingo. It works.

So, here are the steps:
1. Find a shady sd serial number detection tool
2. Flash it on a memory card with a shady vendor-specific flashing tool
3. Insert the new (now shady) card
4. Boot, write down the serial number
5. Find a shady boot image online
6. Edit a shady .ini file of a shady self-signing tool to sign the shady boot image
7. Flash the altered shady boot image with the shady flashing tool on your memory card
8. Copy a shady firmware update on a new card
9. Insert both cards
10. Pray
