I have an array of 1037 records. The soap service only accepts 100 at a time. So, I write code to send an array of 100 records at a time to the soap service in a loop and get a response back of, "The maximum number (100) of records allowed for this operation has been exceeded." Well, I'll try 99 records then. Nope same error. I'll try 50 records, nope I'll just bang my head on the desk now since the documentation and error say it is a record limit of 100. 😠
Look at my code again. I was grabbing 100 records out of the array of 1037 records and storing it in a new array, but I was sending the original array with 1037 records instead of the temporary array in the loop. 😢 I'm going to bed.7 -

Reviewing coworker's code:
Me: I see you're doing a convoluted sort for every element twice to get your two lists in sync... 😐
CoWorker: Yeah. *straight face, no regrets* That's the only way to do this.
Me:... Uh... No? You can just manage one list with a simple struct and then use the the standard sort.
Coworker: Yeah sure I know. But it'll take time. We don't have time.
Me: *aghast* This is embarrassingly bad code!
Coworker: Don't worry, later on I'll use a hashmap for it. But this needs to be pushed now.
Me: *to myself, no you don't need a hashmap*
Okay, you do you but I can't back you on this. It isn't going to take a lot of time to correct it.
Next day.
Coworker: Hey can you review my code again?
Me: You've made the changes already? *in a bored tone, knowing that they wouldn't have changed shit*
Coworker: No this is a different file. Our manager agrees that we can worry about performance later.
Me: Sure. *😀🔨🔨*
Few weeks pass by:
QA: The operation takes absurdly long time to complete even with the smallest data. Ten minutes for X is unacceptable.

The stupid stories of how I was able to break my schools network just to get better internet, as well as more ridiculous fun. XD
1st year:
It was my freshman year in college. The internet sucked really, really, really badly! Too many people were clearly using it. I had to find another way to remedy this. Upon some further research through Google I found out that one can in fact turn their computer into a router. Now what’s interesting about this network is that it only works with computers by downloading the necessary software that this network provides for you. Some weird software that actually looks through your computer and makes sure it’s ok to be added to the network. Unfortunately, routers can’t download and install that software, thus no internet… but a PC that can be changed into a router itself is a different story. I found that I can download the software check the PC and then turn on my Router feature. Viola, personal fast internet connected directly into the wall. No more sharing a single shitty router!
2nd year:
This was about the year when bitcoin mining was becoming a thing, and everyone was in on it. My shitty computer couldn’t possibly pull off mining for bitcoins. I needed something faster. How I found out that I could use my schools servers was merely an accident.
I had been installing the software on every possible PC I owned, but alas all my PC’s were just not fast enough. I decided to try it on the RDS server. It worked; the command window was pumping out coins! What I came to find out was that the RDS server had 36 cores. This thing was a beast! And it made sense that it could actually pull off mining for bitcoins. A couple nights later I signed in remotely to the RDS server. I created a macro that would continuously move my mouse around in the Remote desktop screen to keep my session alive at all times, and then I’d start my bitcoin mining operation. The following morning I wake up and my session was gone. How sad I thought. I quickly try to remote back in to see what I had collected. “Error, could not connect”. Weird… this usually never happens, maybe I did the remoting wrong. I went to my schools website to do some research on my remoting problem. It was down. In fact, everything was down… I come to find out that I had accidentally shut down the schools network because of my mining operation. I wasn’t found out, but I haven’t done any mining since then.
3rd year:
As an engineering student I found out that all engineering students get access to the school’s VPN. Cool, it is technically used to get around some wonky issues with remoting into the RDS servers. What I come to find out, after messing around with it frequently, is that I can actually use the VPN against the screwed up security on the network. Remember, how I told you that a program has to be downloaded and then one can be accepted into the network? Well, I was able to bypass all of that, simply by using the school’s VPN against itself… How dense does one have to be to not have patched that one?
4th year:
It was another programming day, and I needed access to my phones memory. Using some specially made apps I could easily connect to my phone from my computer and continue my work. But what I found out was that I could in fact travel around in the network. I discovered that I can, in fact, access my phone through the network from anywhere. What resulted was the discovery that the network scales the entirety of the school. I discovered that if I left my phone down in the engineering building and then went north to the biology building, I could still continue to access it. This seems like a very fatal flaw. My idea is to hook up a webcam to a robot and remotely controlling it from the RDS servers and having this little robot go to my classes for me.
What crazy shit have you done at your University?9 -
Dev: “Ughh..look at this –bleep- code! When I execute the service call, it returns null, but the service received a database error.”
Me: “Yea, that service was written during a time when the mentality was ‘Why return a service error if the client can’t do anything about it?’”
Dev: “I would say that’s a misunderstanding of that philosophy.”
Me: “I would say it’s a perfectly executed example of a deeply flawed philosophy.”
Dev: “No, the service should just return something that tells the client the operation failed.”
Me: “They did. It was supposed to return a valid result, and the developer indicated a null response means the operation failed. How you deal with the null response is up to you.”
Dev: “That is stupid. How am I supposed to know a null response means the operation failed?”
Me: “OK, how did you know the operation failed?”
Dev: “I had to look at the service error logs.”
Me: “Bingo.”
Dev: “This whole service is just a –bleep-ing mess. There are so many things that can go wrong and the only thing the service returns is null when the service raises an exception.”
Me: “OK, what should the service return?”
Dev: ”I don’t know. Error 500 would be nice.”
Me: “Would you know what to do with error 500?”
Dev: ”Yea, I would look at the error log”
Me: “Just like you did when the service returned null?”
<couple of seconds of silence>
Dev: “I don’t know, it’s a –bleep-ing mess.”
Me: “You’re in the code, change it.”
Dev: “Ooohhh no, not me. The whole thing will have to be re-written. It should have been done correctly the first time. If we had time to do code reviews, I would have caught this –bleep- before the service was deployed.”
Me: “Um, you did.”
<a shocked look from Dev>
Dev: “What…no, I’ve never seen this code.”
Me: “I sat next to Chuck when you were telling him he needed to change the service to return null if an exception was raised. I remember you telling him specifically to pop-up an error dialog ‘Service request failed’ to the user when the service returned null.”
Dev: “I don’t remember any of that.”
Me: “Well, Chuck did. He even put it in the check-in comments. See…”
<check in comments stated Dev’s code review and dictated the service return null on exceptions>
Dev: “Hmm…I guess I did. –bleep- are you a –bleep-ing elephant? You –bleep-ing remember everything.”
<what I wanted to say>
No, I don’t remember everything, but I remember all the drive-by <bleep>-ed up coding philosophies you tried to push to the interns and we’re now having all kinds of problems I spend waaaaay too much time fixing.
<what I said, and lied a little bit>
Me: “No, I was helping Nancy last week troubleshoot the client application last week with the pop-up error. Since the service returned a null, she didn’t know where to begin to look for the actual error.”
Dev: “Oh.”1 -
A programmer once explained Nietzsche like this:
A long time ago, god created the world, but forgot to leave a developer documentation, thus the whole world was like legacy code...
And humans are like the end user of this world, and some among them spent time studying it, using the Moral API, hoping to get a result of "http 200 ok" from our world for the peace of mind. But the true operation of this world is still yet unknown...
As time passes, humans begin to find that in Moral API, good and evil are two base classes, and all the other moral properties (like ethic, justice and stuff) are just other classes based on those two classes through multiple inheritance.
One day, when programmer Nietzsche was observing the world's runtime behavior, he came up with a question:
"Did god really use good and evil as base classes? Could it be that they are actually derived classes?"
Most of the world is currently in the favor of mankind, and god must've wrote individual user cases for it's end users, he thought.
This made Nietzsche thinking: if end users are considered into two cases: the strong and the weak, how would the world be designed base on its user story?
Let's think about the strong, they can bully the weak as they please, and there's nothing the weak can do to stop them. In this case whether the Moral API exists or not doesn't fulfill the need of the strong.
But when it comes to the weak, Nietzsche thinks that because the weak cannot fight the strong, they need to belittle bullying and praise the strong for being nice. When the weak does this, it covers their powerless state to some extent, making them look somehow equal to the strong by being capable of commenting.
God might have coded the Moral API to fit the weak's requirement, also adding some public methods for the weak to comment on the strong. If the strong takes care of the weak, they call him nice and good, if the strong bullies people, they call him bad and evil.
That's when Nietzsche realized, that good and evil are both derived classes from the weak, and the base class should be the strong and the weak.
Then he started a series of studies about the Moral API, and got some thesis that persuaded lots of other end users...7 -

Happy rant.. life is going to change forever. I'm going to be a dad! Operation : Kiddie QA team... Is underway :D5

I’ve never actually had a colleague quit while I was there, buuuut, I did have a colleague disappear, here is that story:
I get hired by this colleague, seems like a nice, perfectly reasonable guy.
I’m supposed to be mentored in the codebase by him after I start.
Literally the day or day after I start, he gets a tap on the shoulder from someone in HR while he’s on the phone. He says he can’t come because he’s on the phone.
The HR woman insists, tells him to leave *everything* and he never returns.
Turns out the police were downstairs to arrest him.
He got caught up in Operation Yewtree which for those that don’t know, was the UK’s sting op on historic pedophilia cases.
MFW my manager gets arrested and the senior dev is too busy to mentor me, so I basically have to sink or swim 🤣4 -
Telling a developer to just start coding (because we need shit done) is like asking the surgeon not to wash he's hands before a operation cause it would save us time.4

The corporate cunts have no clue how manufacturing facilities work. They decided to roll out major changes to their financial systems that control how workers report their hours.
They decide that Dec 29th is a good idea. We are a 24/7 operation and the last 3 days of the year are the busiest time of the year by far trying to meet quotas.
Even today they are trying to finish functionality and are unsure how certain parts will work. This will be a disaster. -
$ sudo apt-get remove UK

After this operation, 1 GB will be lost.

Worst fight I've had with a co-worker?
Had my share of 'disagreements', but one that seemed like it could have gone to blows was a developer, 'T', that tried to man-splain me how ADO.Net worked with SQLServer.
<T walks into our work area>
T: "Your solution is going to cause a lot of problems in SQLServer"
Me: "No, its not, your solution is worse. For performance, its better to use ADO.Net connection pooling."
T: "NO! Every single transaction is atomic! SQLServer will prioritize the operation thread, making the whole transaction faster than what you're trying to do."
<T goes on and on about threads, made up nonsense about priority queues, on and on>
Me: "No it won't, unless you change something in the connection string, ADO.Net will utilize connection pooling and use the same SPID, even if you explicitly call Close() on the connection. You are just wasting code thinking that works."
T walks over, stands over me (he's about 6.5", 300+ pounds), maybe 6 inches away
T: "I've been doing .net development for over 10 years. I know what I'm doing!"
I turn my chair to face him, look up, cross my arms.
Me: "I know I'm kinda new to this, but let me show you something ..."
<I threw together a C# console app, simple connect, get some data, close the connection>
Me: "I'll fire up SQLProfiler and we can see the actual connection SPID and when sql server closes the SPID....see....the connection to SQLServer is still has an active SPID after I called Close. When I exit the application, SQLServer will drop the SPD....tada...see?"
T: "Wha...what is that...SQLProfiler? Is that some kind of hacking tool? DBAs should know about that!"
Me: "It's part of the SQLServer client tools, its on everyone's machine, including yours."
T: "Doesn't prove a damn thing! I'm going to do my own experiment and prove my solution works."
Me: "Look forward to seeing what you come up with ... and you haven't been doing .net for 10 years. I was part of the team that reviewed your resume when you were hired. You're going to have to try that on someone else."
About 10 seconds later I hear him from across the room slam his keyboard on his desk.
100% sure he would have kicked my ass, but that day I let him know his bully tactics worked on some, but wouldn't work on me.7 -
One Thursday noon,
operation manager: (looking at mobile)what the.....something is wrong i am getting bunch of emails about orders getting confirmed.
Colleague dev: (checks the main email where it gets all email sent/received) holy shit all of our clients getting confirmation email for orders which were already cancelled/incomplete.
Me: imediately contacting bluehost support, asking them to down the server so just that we can stopp it, 600+ emails were already sent and people keep getting it.
*calls head of IT* telling the situation because he's not in the office atm.
CEO: wtf is happening with my business, is it a hacker?
*so we have a intrusion somebody messed the site with a script or something*
All of us(dev) sits on the code finding the vulnerabilities , trying to track the issue that how somebody was able to do that.
*After an hour*
So we have gone through almost easch function written in the code which could possibly cause that but unable to find anything which could break it.
Head asking op when did you started getting it actually?
Op: right after 12 pm.
*an other hour passes*
Head: (checking the logs) so right after the last commit, site got updated too?. And....and.....wtf what da hell who wrote this shit in last commit?
* this fuckin query is missing damn where clause* 🤬
Me: me 😰
*long pause, everyone looking at me and i couldn't look at anyone*
The shame and me that how can i do that.
Head: so its you not any intrudor 😡
Further investigating, what the holy mother of #_/&;=568 why cronjob doesn't check how old the order is. Why why why.
(So basically this happened, because of that query all cancelled/incomplete orders got updated damage done already, helping it the cronjob running on all of them sending clients email and with that function some other values got updated too, inshort the whole db is fucked up.)
and now they know who did it as well.
*Head after some time cooling down, asked me the solution for the mess i create*
Me: i took backup just couple of days before i can restore that with a script and can do manual stuff for the recent 2 days. ( operation manager was already calling people and apologising from our side )
Head: okay do it now.
Me: *in panic* wrote a script to restore the records ( checking what i wrote 100000000 times now ), ran...tested...all working...restored the data.
after that wrote an apology email, because of me staff had to work alot and it becomes so hectic just because of me.
* at the end of the day CEO, head, staff accepted apology and asked me to be careful next time, so it actually teached me a lesson and i always always try to be more careful now especially with quries. People are really good here so that's how it goes* 🙂2 -
Some time ago I quit my job at a big corporation. Getting treated like a resource, a production line robot, just isn't for me.
My current job is way better. Small company, lots of freedom, getting to work on multiple projects, the result counts. But, as a small company, we also collaborate with big corporations. So I joined a team at one.
Watching my coworkers there, I'm reminded of robots again. Lunch break? 15 minutes tops. Just shovel some edibles into your face hole and back to work. Five minutes break between meetings? Open laptop, work work work. The concept of "needing rest" seems entirely foreign to them.
Yesterday our product owner "relayed some criticism" from other team members to me. Apparently, me going to the toilet in breaks is "suddenly disappearing". Or me not replying within 15 minutes in the chat is outrageous. And then he tried to berate me how I'm "his developer" and his team's tasks have top priority. So, according to the PO the problem is me and I should "get used to their mode of operation".
How about "no". I quit a fucking job because that "mode" is simply inhuman. After that feedback, you bet I'm taking my legally protected 30 minutes lunch break and any other break I can. Because fuck yourself, you're not going to burn me out. The best part, that team has smokers who "suddenly disappear" twice as much as I do, but apparently that's somehow a-ok.
I had to remind him that his project is just one of several I'm working on, so no, not "his dev". While that wasn't exactly a powerful comeback, it did shut him up. Still going to talk to my boss on Monday, at least to ensure that the PO can't talk shit about me behind my back.4 -
My Love I am writing to you from the front lines roughly 1 month into Microsoft Access. I hope you are doing alright and no harm has found you.
You might have heard the news that it has not been going well for us. The truth is we were not prepared in any way for this. We are constantly facing problems with the code and when we understand one function another two are referenced inside of that function.
The high command does not provide us guidance, truth be told I do not think they know what their application is doing. I am surprised we got this far. Our new objective is to focus our primary forces on the if/else and cases. The name for this assault is "Operation Logical Function" and I fear for my life as I do not know what is in those cases or where the road will lead.
Morale is very low, many of the soldiers spend time writing letters to their loved ones, recreating their blog for the 5th time or just daydreaming when they were free from this tyranny of legacy war.

My love and thoughts always with you , your John7 -
Update on UWP File explorer! Exciting stuff first!
Reveal style was applied to the home page grid (That thing in WinX where the borders change color in proximity to the mouse)
Clickable buttons in the title bar! This is the first step to tabs!
Converted a lot of things that were generated dynamically in C# to UserControls in XAML, for easier reading and even improved code-behind options.
Pulled my hair out getting rid of System.IO - System.IO is not made for UWP and stops working in certain situations. Now using Windows.Storage, which is a lot more async. I have gotten much friendlier with the dispatcher.
Pain from the operation is really fading and school doesn't start for a couple days, so I hope to get a beta out before school starts, and more realistically, get the tab system done before school starts.10 -
I started early in my childhood days, nobody had cellphone or internet here, my phone number was 3 digits long and my home country started to recover from 44 years of communism.
My first dev project was probably to copy game from newspaper to Atari 1300XE
Article listing was around 10 pages long and if you made mistake program didn’t run.
It took me a while I can’t remember how long but probably whole day and I was finally able to play it.
I don’t remember what was game about but later on I learned some BASIC from book and was able to color the screen and stuff like that.
I was about 6 years old.
I also remember that Atari computer had tape recorder where you put cassette to load game.
Some more complicated games were loading more then hour and you need to walk very carefully around or your walk can cause error and operation would fail.
Besides that there were national radio auditions about Atari where at the end they played code sound wave so you can record it on your cassette and then play software from radio on your Atari.
I never managed to do it cause I was living near military airport and pilots were practicing landing and starting above my home causing radio signal noise and breaking my software recoding.
I can probably say that highly accelerating plane could cause game loading problem and it’s not a joke.8 -
Someone gave me a web method that return a boolean.
The Boolean tells me if the operation went well.
True means everything went well
False means something went wrong
But
It throws exception when something went wrong.
Basically they implemented a Boolean system to check if everything is alright but I also have to add a try/catch if something is not right.9 -
I love Linux, but its community can be so full of incompetent assholes..
Just now I asked in Freenode ##linux how to get the process ID of my current running process in bash. I got my answer - it's a shell built-in called "$$".
Then people start to nitpick some more - why do you need it? How is that different from an exit? - to which my response was.. well I know the whole idea behind exit codes, and I'd use it whenever possible, in all defined behavior that allows my program to terminate itself whenever it can. This pidfile however would be used to exit itself and provide diagnostic information whenever the program enters undefined behavior - a segfault in C language. Scenarios in which I don't have full control over the script's behavior anymore, such as the system entering an unworkable state where the system stalled, still got some binaries in RAM but the rootfs got unwritable, such as now - very helpfully, thanks HP! - when my laptop likely overheated and shat itself. I issued sudo reboot into it, but even that wouldn't issue properly anymore due to the /sbin/poweroff binary becoming inaccessible too. I had to issue a hard power cycle.. one of the few times in which I'm thankful to HP for actually causing shit like this, lol.
Point is, that undefined behavior is what I'm trying to mitigate against. I certainly can't let any files other than diagnostics remain in nonvolatile storage like that, especially when their state should be predictable in order to ensure good operation (like files expressing whether the script is already running or not, i.e. lock files).
Back to that IRC chat. Aside from the answer, I got ridicule from people who probably don't even know how to properly compile a kernel. Ubuntu users, overconfident scum. Sometimes I feel like I should ask questions in channels like #archlinux only, where such incompetency is ridiculed on its own.13 -
So this story is from my University days. I was in the 6th semester back then, studying CS.
My University website was pretty shitty. Basically it was one of those old ass website that said "Best viewed in IE8". Anyway, I was snooping about the website, trying to find some news regarding an event.
I logged into my account, and randomly browsed into the leave request portal. This was a basic HTML form where students could apply for leaves from the classes and see the status of the leaves, if they have been granted or not. I noticed that the link to the request portal from the student login welcome page was actually something like http://univ.com/student/index.php/..., here 1234567 was my student ID. Yep, it was hardcore into the page, and sent as a GET request on being clicked. That was their idea of authentication I guess. I change the student ID to someone else's, and it let me login as that person.
Long story short, I wrote a little python script to login as every person from the starting of student IDs, till the end, then submit a leave request with a random dumb reason like "can't come, at the strip club" or "going for sex change operation". What I did not know was that when a request is submitted, a text message is also sent to the student's guardians phone number. I ran the script.
That day, over 1000 parents received text messages from the University saying that their kids have applied for a leave from random date to random date for some retarded reason. It was a blast. Students were talking about how someone had "Hacked" into the system.4 -
RANT TIME!
Sorry guys, I know this is devRant and probably not a place to post this but am fucking burning with fury and fatigue! I should probably develop elecRant and post it there instead.
I FUCKING HATE POWER ELECTRONICS!!
I am in my final year of electrical engineering and I can fucking say with confidence that power electronics is the most fucked up unit I have seen in my life. A whole load of useless math from simple RLC circuits just to make students' lives miserable. For those who might not know, power electronics is some unit that involves use of solid state electronics(transistors, diodes etc) for power applications(switching mostly). Basically things like inverters and converters. UPS systems are an example of their applications.
Now don't be fooled by how that sounds cool and so smart, this shit is fucked up. These circuits in the attached picture might just seem like simple RLC networks with some BJTs, but they are devils in their own right. They fucking need some advanced unnecessary calculus and Fourier analysis to even calculate the simplest output current!! Worst still, some of these motherfuckers have more than 1 mode of operation,needing one to analyze some fucking 100+ waveforms. I fucking hate this shiit! I hate it!
You might say that i am just being lazy and don't want to study. Let me tell you something, FUCK YOU TOO!!19 -
An excerpt from the best rant about whiteboard interviews posted on the internet. Ever.
"Well, maybe your maximum subsequence problem is a truly shitty interview problem. You are putting your interview candidate in a situation where their employment hinges on a trivia question. — Kadane's algorithm! They know it, or they don't. If they do, then congratulations, you just met an engineer that recently studied Kadane's algorithm.
Which any other reasonably competent programmer could do by reading Wikipedia.
And if they don't, well, that just proves how smart the interviewer is. At which point the interviewer will be sure to tell you how many people couldn't answer his trivially simple interview question.
Find a spanning tree across a graph where the edges have minimal weight. Maybe one programmer in ten thousand — and I’m being generous — has ever implemented this algorithm in production code. There are only a few highly specific vertical fields in the industry that have a use for it. Despite the fact that next to no one uses it, the question must be asked during job interviews, and you must write production-quality code without looking it up, because surely you know Kruskal’s algorithm; it’s trivial.
Question: why are manhole covers round? Answer: they’re not just round, if you live in London; they're triangular and rectangular and a bunch of other shapes. Why is your interview question broken? Why did you just crib an interview question without researching whether its internal assumption was correct? Do you think that “round manhole covers are easier to roll" is a good answer? Have you ever tried to roll an iron coin that weighs up to 300 pounds? Did you survive? Do you think that “manhole covers are circular so that they don’t fall into manholes” is a good answer? Do you know what a curve of constant width is? Do you know what a Reuleaux triangle is? Have you ever even been to London?
If the purpose of interviewing was to play stump the candidate, I’d just ask you questions from my area of specialization. “What are the windowing conditions which, during the lapping operation on a modified discrete cosine transform, guarantee that the resynthesis achieves perfect reconstruction?” The answer of course is the Princen-Bradley condition! Everyone knows that’s when your windowing function satisfies the conditions h(k)2+h(k+N)2=1 (the lapping regions of the window, squared, should sum to one) and h(k)=h(2N−1−k) (the window should be symmetric). That’s fundamental computer science. So obvious, even a child should know the answer to that one. It’s trivial. You embarrass your entire extended family with your galactic stupidity, which is so vast that its value can only be stored in a double, because a float has insufficient range:"

My potato lagged with the temperature too high error message.
So I decided to operate on it. Last operation was about 40months ago or more.
Every time I opened and reassemble something, I always ended up with extra screws (check comments). Wish they were gold 🤔
And this is probably the last operation I could perform on it. I must save fast to buy a desktop 😥13 -
Was in a middle of competitive coding trying to do some operation on a nxn matrix. Wrote this code.

- Team_leader_1: I know you're a frontend developer, but trust me NodeJS has threads :) sync operations don't block the main thread :)

The thing with meetings is that most don't know what a (formal) meeting is.
A meeting has a specific time frame, a defined agenda with specific topics and a moderator or an agreement on a common netiquette.
That's a meeting.
A meeting is not a place to put your willy on the desk and proof to everyone that your cock is thx to operation a long schlong who won't get hard, nor that you don't know how to shave, even less to measure the size of your genitals.
It's neither the time to eat and slurp like a fucking hobgoblin, nor to drink like an alcoholic who hasn't had a drop of alcohol in the last hour.
Parents, I don't care what your satanic offspring achieved today, nor how cute they are, even less what booboo they have.
Crybabies, keep your whining for after meeting time, maybe even stop crying and just have a nice talk outside of allocated time frames to discuss whom hurt whom the most and who has the most sand in his clit.
Get to the fucking point.
If I wanted to read a trilogy to understand what you contribute, I'd have written it on the agenda.
If it's not on the agenda, cram it in your butt cheeks for the next time you need to shit.
If you can't converse with people at all, the meeting is allocated at least 24 hours before it happens.
Prepare yourself for goddamn sake.
You could even read out a predefined text if you want, noone cares.11 -
Okay you bastards ya got me: I fucking enjoy using Linux as my dev environment.
There, I SAID IT -
BUT DON'T THINK FOR A SECOND IT MEANS THAT I STOPPED HATING IT
Oh the fucking love hate relationship to fucking Linux.
"Hey, ihatecomputers! How many hours per year did you spend fixing internet connectivity issues on Windows?" you ask. Well, close to fucking 0 you goddamned imbecile. But on Linux? I don't even want to talk about it.
And what about that time when I wanted to connect my bluetooth headphones so I could listen to music while studying? Well, by the time my headphones were connected to my machine (usually a one second operation) I had no time left for, you know, actual studying. Oh my god, it's the most trivial fucking thing.
Well, at least that particular issue got solved.
Unlike that fucking Ethernet connection which has been fucking out of commission since I started using fucking Linux. Wifi works just well enough to make it not worth pouring more time into troubleshooting that shit, but just barely though because my wifi IS FUCKING DOGSHIT ON LINUX
...
But fuck me if it isn't it the most lean thing ever! It's the goddamned opposite of bloated. So smooth and snappy. And free as in slurred speech, or whatever. It makes me happy. When I'm not seething with rage, that is.
Yeah I guess that's it, thanks for tuning in.

Just did my first JobIntentService on Android. Hoo, boy.
The problem: I need to send a network request.
The issue: Android.
Of course, you can't do network on the main thread. That's silly in any application. Android really does try to punish you, though. The Android lifecycle can really fuck you over here. Imagine a long-running network operation, like 15 seconds. Plenty of time for the user to do something silly, like rotate the screen.
If you opened up a good old new Thread from Java, you'd get a crash because of a screen rotation. Same thing with Android's AsyncTask, which is the top answer on StackOverflow. AsyncTask is made for things that will take no longer than a few seconds (less than 5!). Network, especially cell network, can take longer.
So the solution? Create a JobIntentService class. It's a service, it will run in the background. You need to register it in your Android Manifest and ask for a new permission (wake lock). You need to implement another class for the receiver, and then you need to go to your activity and implement the receiver interface you just wrote.
Just. For. A. Network. Request!
And as far as I'm aware, this isn't even that bad considering the rest of Android's bullshit.
What a headache!8 -
Me in school: Math? When do I need know those details? I can look them up and just code it.
Me in high school: Computer science is way too math-y. I want to code!
Me coding php: Just make it work.
Me coding typescript: Just make it work.
Me coding scala: Just make it ... what ... how do I make it work!?!
Me asking stackoverflow: How do I do X in scala some functional programming stuff in mind in order to keep immutability.
Somebody way smarter than I: "In scalaz, a function A => A is called an endomorphism and is a Monoid whose associative binary operation is function composition and whose identity is the identity function"
Me now: Fuck my old arrogant self.1 -
Just wanted to spread awareness about a Windows 10 devRant app called "devRant Unofficial". It's literally a 1:1 clone of the Android and iOS apps.
Maybe the devRant team could contact the dev for come co-operation and get an official app for Windows 10 with little to none effort?
It works on mobile and PC so I can easily use it on my Lumia and Surface. I know most of you guys here use macOS, but for us Windows devs, having an official app would be cool.
I know Valve talked to an unofficial developer of the Steam app for Windows Phone, and gave him approval for removing the "unofficial" tag. I suggest you guys do the same.
Happy 2016's death everyone, and sorry for the long and boring post!13 -

Like WTF!
"the value of NaN is result of an operation that cannot produce a normal result. NaN is not equal to any value, including itself."
The funny or wierd part (maybe just for me):
"You can detect NaN with the isNaN(number) function".
Like whaaat? 😶25 -
Time for a REAL fucking rant.
io_uring manpages say you can set the CAP_SYS_NICE capability to allow SQPOLL to work. You can't, you still get an operation not permitted errno result.
Why? I checked, it says 5.10 mainline is required. Pretty sure I just manually downloaded and installed the Deb's myself. uname reports that I am at 5.10. So what gives?
Maintainer submitted a patch because they fucked up and made the *actual* capability check look for what's basically root permissions (CAP_SYS_ADMIN... c'mon...) and is now trying to rectify a glaring security shortcoming.
Patch hasn't been accepted or even addressed yet but they already updated the manpages with the estimated mainline kernel release as if it had made it into the release candidate. Manpages have made it into latest debs but the actual change has not.
Where the fuck is the Linus Torvalds that would ream the fuck out of shitty developers doing shitty things? The political correctness climate has discouraged such criticism now and the result... this. This fucking mess, where people are allowed to cut corners and get away with it because it would hurt their feelings when faced with pressure.
I'm not just guessing either. The maintainer has already said some of the "tone" of criticisms hurt his feelings. Yes, sorry, but when you claim 90% speedup over a typical epoll application using your new magical set of syscalls, and nobody can even get 1-2% speedup on a similar machine, people are going to be fucking skeptical. Then when you lower it to 60% because you originally omitted a bunch of SECURITY RELATED AND CORRECTNESS CHECKING CODE, we're going to call you the fuck out for fudging numbers.
Trying to maintain the equivalent of academic integrity within the computer science field is an exercise of insanity. You'd be fired and shunned from publishing in journals if you pulled that shit in ANY OTHER FUCKING FIELD, but because the CS scene is all about jerking each other off at every corner because the mean people keep saying mean things on Twitter and it hurts your feelings therefore we're all allowed to contribute subpar work and be protected from criticisms when others realize it's subpar.
These aren't mistakes anymore, it's clear you're just trying to farm clout at Facebook - maybe even FOR Facebook.
Fuck you. Do it right, the first time. Sick of shitty code being OK all of a sudden.2 -
Maybe this ever tightening straight jacket of surveillance and restrictive legislation is pushing the internet in the right direction. We might end up with a proper free and anonymous interwebz.
Personally, I'll start worrying when they ban the operation of Tor nodes... And that will probably pass easily since regular folk don't know the implications. The smear campaign will be ez mode: just call it a hotbed of pedophilia and criminal activity and push the new laws as something along the lines of Put an End to Naughty Individuals and Scumbags (PENIS) act. Done and done.
I mean... if they can threaten to take away the memes without being stopped then there's nothing they can't do, lol.3 -

- CPU is really hot
- CPU fan doesn't work
- BIOS warning disabled because the lowest regular fan level is 0 RPM
Luckily, I still had some cheap 120mm fan which is a bit louder, but works. What's astonishing is that in normal operation, i.e. without full load, the case fans alone provided enough air stream for the CPU cooler.8 -
It’s still to easy.
I hope one day software will get so complicated no one will be able to fix it.
Somewhere in future :
- government established law that new AI system is only one that can accept new law
- every financial operation is monitored by government supervision AI
- we developed robots that are taking care of us
- everyone is happy cause work for money, shelter and food is now optional
- education is fully digital and managed by AI
- whole knowledge is based on asking questions, we don’t need to write and read anymore
- we use one common language and our knowledge specialization increased
A little more time passed by in this utopia.
- after power loss most of data got corrupted
- last man who knew how to restore backup died last night ( R.I.P. admin we will not forget you )
- people trying to save knowledge base to rebuild part of this civilization but no one knows how to make a paper because it haven’t been used for ages
- we decided to put what is left from knowledge on stone but we forgot how to write since everything is audio or video and most of time we were spending in VR
- someone decided that we draw some pictures
- all of use are now drawing animal heads like we remember ourselves from VR, let people know our tech is good
- some people love cats so they try to make cats from stones
- volcano eruptions destroyed most of stones that we made
Starving waiting for another respawn of my DNA sequence. I hope we manage to survive this time.4 -
I think, after a few weeks, I'm actually quite enjoying that the Android SDK is genuinely awful.
We all know the feeling: "This is shit, whoever designed this is a fuc...oh, I get it. This is pretty cool actually."
So, it's nice to encounter a genuine dumpster fire of a platform.
I think the beautiful thing about its absolute obsession with providing a context to every single operation, is that you end up passing it around so much that the very concept of context becomes redundant.
Honestly, half of the stuff in here I've just attached to a global statics class, because it saves having to request a context, or a manager or some fucking kind of adapter, and it works just fine.
I've started to laugh when I look up a solution and see the browser scrollbar shrink into infinity, because the recommended answer is about two whole pages' worth of boilerplate to make the back button disappear or something.
I don't think there's been a single moment where I've just been in the flow of writing code. Pretty much all of the process is grafting boilerplate into it.
Not long til deadline, thank fuck.2 -
Buffer usage for simple file operation in python.
What the code "should" do, was using I think open or write a stream with a specific buffer size.
Buffer size should be specific, as it was a stream of a multiple gigabyte file over a direct interlink network connection.
Which should have speed things up tremendously, due to fewer syscalls and the machine having beefy resources for a large buffer.
So far the theory.
In practical, the devs made one very very very very very very very very stupid error.
They used dicts for configurations... With extremely bad naming.
configuration = {}
buffer_size = configuration.get("buffering", int(DEFAULT_BUFFERING))
You might immediately guess what has happened here.
DEFAULT_BUFFERING was set to true, evaluating to 1.
Yeah. Writing in 1 byte size chunks results in enormous speed deficiency, as the system is basically bombing itself with syscalls per nanoseconds.
Kinda obvious when you look at it in the raw pure form.
But I guess you can imagine how configuration actually looked....
Wild. Pretty wild. It was the main dict, hard coded, I think 200 entries plus and of course it looked like my toilet after having an spicy food evening and eating too much....
What's even worse is that none made the connection to the buffer size.
This simple and trivial thing entertained us for 2-3 weeks because *drumrolls please* none of the devs tested with large files.
So as usual there was the deployment and then "the sudden miraculous it works totally slow, must be admin / it fault" game.
At some time it landed then on my desk as pretty much everyone who had to deal with it was confused and angry, for understandable reasons (blame game).
It took me and the admin / devs then a few days to track it down, as we really started at the entirely wrong end of the problem, the network...
So much joy for such a stupid thing.18 -
Fixed a bug in my emulator that was completely breaking almost every program I ran on it.
Turns out the virtual ALU set its arithmetic flags (zf, nf) even when a non-arithmetic operation was run. -
Saw a question on SO asking why foreach was slow with big data.
The code provided was 6 nested foreachs (basically a cartesian product between an array of arrays, and 4 other arrays).
Inside, a select query and an "update or create" operation.
"But why is foreach so slow?"4 -
Lessons I've learnt so far on programming
-- Your best written code today can be your worst tomorrow (Focus more on optimisation than style).
-- Having zero knowledge of a language then watching video tutorials is like purchasing an arsenal before knowing what a gun is (Read the docs instead).
-- It's works on my machine! Yes, because you built on Lenovo G-force but never considered the testers running on Intel Pentium 0.001 (Always consider low end devices).
-- "Programming" is you telling a story and without adding "comments" you just wrote a whole novel having no punctuation marks (Always add comments, you will thank yourself later for it I promise).
-- In programming there is nothing like "done"! You only have "in progress" or "abandoned" (Deploy progressively).
-- If at this point you still don't know how to make an asynchronous call in your favourite language, then you are still a rookie! take that from me. (Asynchronous operation is a key feature in programming that every coder should know).
-- If it's more than two conditions use "Switch... case" else stick with "If... else" (Readability should never be under-rated).
-- Code editors can MAKE YOU and BREAK YOU. They have great impact on your coding style and delivery time (Choose editors wisely).
-- Always resist the temptation of writing the whole project from scratch unless needs be (Favor patching to re-creation).
-- Helper methods reduces code redundancy by a large chunk (Always have a class in your project with helper methods).
-- There is something called git (Always make backups).
-- If you don't feel the soothing joy that comes in fixing a bug then "programming" is a no-no (Coding is fun only when it works).
-- Get angry with the bugs not the testers they're only noble messengers (Bugs are your true enemy).
-- You would learn more than a lot reading the codes of others and I mean a lot! (Code review promotes optimisation and let's you know when you are writing macaroni).
-- If you can do it without a framework you have yourself a big fat plus (Frameworks make you entirely dependent).
-- Treat your code like your pet, stop taking care of it and it dies! (Codes are fragile and needs regular updates to stay relevant).
Programming is nothing but fun and I've learnt that a long time ago.6 -

I wish I can fucking clone myself.
We have been providing digital marketing services for like 5 years without having a proper QA team. Well because we cannot afford to hire one. Technically I am supposed to check and control the quality of our operation team. But I have been juggling so many balls and couldn't do that properly.
So this year we decided that we have to seriously take care of that. But we are providing all kinds of services and creating a QA team for all those services is gonna be costly. We wanna solve it, but also doesn't wanna hang ourselves with another rope. So we have decided to just found a QA team with leaders from various departments mainly Sales and Customer Services. They are the ones who have talked with clients. So they should be able to judge the quality of the services our operation made.
It is a fucking nightmare. It is like we have doubled the amount of clients. And that extra half of those newly popped up clients are sitting in our office. -
"Hello, the drive of your XYZ server is getting full, would it be possible to prune some of the unused and/or old docker images and layers there please? Alternatively, we can offer to replace the drives with a higher capacity models for FOO extra per month"
"Hello, the disk use keeps growing and has reached the 95% mark, please prune some of your images to make space for new. If you wanted to choose the alternate option of disk capacity increase, we would have to do that as soon as possible, otherwise you may run out of space before the RAID array rebuilds"
"Hello, your server XYZ has completely ran out of disk space. Any changes that would require data being saved on disk may and probably will fail. Please free some space as soon as possible"
Ugh, I hate clients that just don't cooperate until shit hits the fan...
And no, we could not prune the space ourselves, its not our data to delete whenever we think it necessary.
We merely manage the machine's operation, keeping it online and its services running.2 -
TL;DR just read this
So my current (student) job. Asked me to count inventory. Did so, on paper because nobody had a list of the product barcodes for easy cumulative scanning. I also made records for every single barcode. Then I had to key it in onto the Bookkeeping and sales software thing. They don't have keyboard shortcuts, so I quickly made an ahk script.
Had to manually type in everything 3ven though I had a digital listing.
Software lets you print barcodes for products but gives you an error when you try because you haven't assigned a code. WHICH YOU CAN'T DO IN THAT Crap. You also can't search for a product based on code.
Found out it used access as a back end for that buggy c++ thing that crashes with 'operation not permitted' when you press the red x. Great! Now I can import! And there is a barcode field. Wow. Fucking fantastic. What a fuckfest.
Their website. Their fucking website. Great from a user's standpoint, but my God. It uses joomla! However, version 2.5. That hasn't been supported for a long time. Part of the images are hard coded into the theme. The text editor flips. Adding a page sometimes works, sometimes it doesn't, and sometimes makes 2 pages.
And their cnc lathe runs on a laptop with Windows 3 on it, but hey, fine5 -
// Tired as fuck adventures, yay
I was once coding and researching for a school project, it was around 1AM (yeah, I'm a pussy that needs to sleep at 12AM, otherwise I'm useless all the day long) and a friend was with me, he was doing another stuff.
Suddenly, out of the blue, he asks me "Hey, how much is 12 multiplied by 430?", so I say "Let me check", press Win+R, type "notepad", enter, write operation and wait looking at the screen.
"why this does not work?" I thought for some seconds until I realized I fucking typed in notepad and not in the calculator.
Just laughed my ass off and went straight to sleep. Until today, my friend thinks I'm deranged.1 -

Firefox and Chrome removing FTP support in 2021 was a terrible decision.
Web browsers were simply the more convenient FTP browsers, more than file managers, due to browsers' built-in multimedia capabilities like photo viewing and opening documents, distinct purple highlighting of already opened directories and files, browsing history, familiar mouse shortcuts like middle click for new tab, and no possibility of accidental writes due to a botched drag-and-drop operation or similar.
If I wanted to browse an FTP server in "read-only mode", web browsers used to be the preferred choice.12 -
Since we're limiting this to things on my desk I can't do any more deep cuts out of my calculator collection, but this one is still somewhat interesting.
The HP 32S was my friend throughout university, it replaced the 15c I used before which does not live on my desk. The notable thing about the 32s is the fact it's an RPN calculator. RPN calculators are the best way to have friends never ask to borrow your calculator. The exchange will start by them asking to use it, you saying sure, and them handing it back a few minutes later without saying a word.
There's two kinds of people in this world. People who go "wtf" in an interview when asked to create a calculator program using a stack, and people who were oddballs and for whatever reason used reverse polish notation devices.
For those not familiar, rather than entering values into the calculator in "10+10" fashion, you instead provide it a compositional set of values until an operation is provided (10,10,+) at which point it executes. The why is, this type of operation allows the calculator to more naturally process operations, and eliminates the need for parenthesis which makes the operations less error prone in practice and easier to track.
The 32s had a 4 year run before being replaced by the 32SII. In the same way using a Curta will give you a significant understanding of how radix computations and floating points work. Using an HP 32s (or any of its predecessors) will do the same for algebraic functions, because you had to program them yourself using a basic label address system that also had subroutine support.
Kids who grew up with graphing calculators don't know how good you had it 😋4 -
I usually work in a two person team on a hybrid application we are developing, using AngularJS and node.
This normally works okay, because he handles the back end (he's been on the project since January last year, I joined in August as a placement student), and I handle the front end.
However, due to Christmas holidays and such, he's ended up taking an entire month off, and won't be back until the end of January.
I've dabbled in back end before, some routes and that for SQL queries, but nothing serious.
Last Tuesday our core service for the application that needs to be updated in real time broke and pissed off the API provider because we were hammering them with requests.
My first day on back end and this happened. I didn't really know what to do, and had to call my teammate to ask what to do. I essentially just restarted things, and left them as is, until I could find a solution.
From there, I had to mock the operation of the service (which is a complex enough beast) to figure out the problem, and find a fix. Our app more or less hinges on this service, so if it messes up, it's the end times.
All of this while flying on what I've interpreted because the guy that's on holidays was the only guy that knows more about this project than I do.
To make things worse, the clients are being very particular because they're waiting on investments and don't have money to pay our company. So, if they're paying for 5 days work, they're going to put in 5 days of project development. The problem is that their interpretation of 5 days of project development has not changed from when there were two people on this project.
There are 40 tickets in this sprint (ends Friday) and 35 of them are assigned to me. Granted, not all of those take a day to do, but estimates don't mean anything, I guess.

Just finished an assignment yesterday where we had to code a math problem in assembler in under 20 lines
looking at the task: Hey, we already did this in Python
*building own modulo Operation for that cause we cant use it*
*freaking out when realizing it's just not posibble in 20 lines*
Then scrolling up the wikipedia page to see you've spend hours trying to implement the wrong thing3 -
Writing coroutines for io_uring. Submissions aren't working (they go through but the operation never seems to complete). Just fixed a few segfaults because of error cases not destroying coroutine handles correctly. Been on this for two days, finding more and more things I need to do that unrelated to the task at hand. Don't have issue tracking set up yet because haven't had time. Mountain of things that need to get working just for a demo is only growing. Layered maps of data structures and code flow are in my head as I'm trying to mentally debug some of this. I'm focused, completely dead to the outside world.
Then I feel a small scratch on my cheek. Three hours of mental mapping and a deep stack of thought, vanishes into thin air in a single moment.
The trade-off is worth it though.10 -
Still on the primenumbers bender.
Had this idea that if there were subtle correlations between a sufficiently large set of identities and the digits of a prime number, the best way to find it would be to automate the search.
And thats just what I did.
I started with trace matrices.
I actually didn't expect much of it. I was hoping I'd at least get lucky with a few chance coincidences.
My first tests failed miserably. Eight percent here, 10% there. "I might as well just pick a number out of a hat!" I thought.
I scaled it way back and asked if it was possible to predict *just* the first digit of either of the prime factors.
That also failed. Prediction rates were low still. Like 0.08-0.15.
So I automated *that*.
After a couple days of on-and-off again semi-automated searching I stumbled on it.
[1144, 827, 326, 1184, -1, -1, -1, -1]
That little sequence is a series of identities representing different values derived from a randomly generated product.
Each slots into a trace matrice. The results of which predict the first digit of one of our factors, with a 83.2% accuracy even after 10k runs, and rising higher with the number of trials.
It's not much, but I was kind of proud of it.
I'm pushing for finding 90%+ now.
Some improvements include using a different sort of operation to generate results. Or logging all results and finding the digit within each result thats *most* likely to predict our targets, across all results. (right now I just take the digit in the ones column, which works but is an arbitrary decision on my part).
Theres also the fact that it's trivial to correctly guess the digit 25% of the time, simply by guessing 1, 3, 7, or 9, because all primes, except for 2, end in one of these four.
I have also yet to find a trace with a specific bias for predicting either the smaller of two unique factors *or* the larger. But I haven't really looked for one either.
I still need to write a generate that takes specific traces, and lets me mutate some of the values, to push them towards certain 'fitness' levels.
This would be useful not just for very high predictions, but to find traces with very *low* predictions.
Why? Because it would actually allow for the *elimination* of possible digits, much like sudoku, from a given place value in a predicted factor.
I don't know if any of this will even end up working past the first digit. But splitting the odds, between the two unique factors of a prime product, and getting 40+% chance of guessing correctly, isn't too bad I think for a total amateur.
Far cry from a couple years ago claiming I broke prime factorization. People still haven't forgiven me for that, lol.6 -
What is it with devs (not all, by any means!) who don't understand networks or basic computer operation? I'm not talking about anything complex, but things like the dev who asked if his IP address could be whitelisted so he could remote in from home. We asked what his public IP address is and he said 10.0.0.27.
Or the new dev who started and said her laptop camera didn't work and logged a ticket, only to be asked if she had the camera cover open or closed and said, "oh, that's what that lever is for."
Don't get me wrong - many devs and sysadmins and IT people of all fields are excellent. And there are some who are crap in every field. This is no rant about devs in general, just *these* crap devs that I can only throw my hands in the air and think, well, they scored ok in the SQL test.4 -
Unpopular opinion: unit tests are often overrated.
Although a well written test suite is almost essential in some parts of the application (I.E. business logic) I cringe when I see hundreds or thousands of line which “mocks” everything to test a micro service which just does CRUD operations on a database, in cases like that unit tests are just a waste of time because almost every operation involves a mock which may not behave like the real database and often needs to be rewritten when the code undergoes a huge refactoring. In these case a integration test suite is faster to write and way more helpful.9 -
If an http request can't perform the requested operation, should server send 500 error code? Or 200 with status and status message in response?

!rant && Thanksgivings++
I am truly thankful to be a programmer for it is the only job on Earth where doing mistakes is the profession itself.
Think about it. We make more mistakes than other professions on DAILY basis. If a doctor miss a step during a diagnosis or an operation, a fucking human being might die. Engineers, lawyers, teachers you name it. They are not allowed to make mistakes.
Us? We are earning money from other people for all the hours we spent fixing the mistakes which we made in the first place.4 -
We are a small company, and our CEO and CTO attends our daily standups(not sure why)
At the end our CTO, after a little discission with our PM, goes: “This” is more importent and should be gone first - its money to the company.
Pm: Fine but then “that” wont be worked on for now.
Cto: ohh okay, but “this” is really importent, so do it first.
Standup done, people returns to work.
1 minut later, Cto comes into the dev room.
Cto: “something else” is also really really importent.
Pm: ok, so then we do “something else” instead and we will put “this” on standby for now.
Cto: and remember “operation” has the highest priority of all.
For fuck sake... just pick one or decide what it is you want....
Cto has no clue to what he is doing. Does not have a long term plan, other then get money into the company based on really short term goals.
Easy to say im not his biggest fan, and I am a 100% sure he knows this.5 -
In highschool, I was looking around for schools and universities at which I would start my student career. I went to a grad school one day, to see what it was like to be a student there. The first class I visited was programming for embedded systems. We got the assignment to write Java code to control a boom barrier. The teacher had written the template. And I kid you not, the template had a method of around 20 lines of code - without comments - with the purpose of carrying out a logical OR operation. An operation that literally can be done using an operator in Java: |
Why oh why do they let these people teach, with the result that the students will get used to these bad practises...5 -
Coolest project I worked on was the one that let me learn to code.
It was a mobile calculator for the blind. The app counted the user's taps to come up with the number they wanted, instead of having them hover their finger around the screen to find each digit. Then each operation was mapped to a swipe gesture.1 -
We were documenting a feature which has system wide affect. We’ll be delivering it to customer on Monday.
So we’ve asked the colleague who worked on it about how it works and asked few follow up questions that arise during the documenting. All were good.
Comes Friday when I had a question as some things didn’t add up and I checked the source. To my surprise the very core operation colleague explained us works in exact opposite way. I kid you not in %50 percent of the documentation we ramble about why it was implemented this way since it is faster/safer best practices bla bla.
Moreover we’ve already had some exchange with the customer and we informed(misinformed) them about this core operation...
Also changing the behavior will reduce the overall speed as it will cause extra branchings. Other option is to rewrite the documentation and inform(re-convince) the customer. If it was me I wouldn’t trust us anymore but we’ll see.
I really don’t know what to say about this fucker why would you say something if you’re not sure of it or why the fuck you didn’t confirm in the last 3 weeks....
Anyway we have a meeting on Monday morning to discuss how to proceed, that’s gonna be fun!1 -
- a split keyboard with a touchpad in the middle that will let you control all gestures on a computer
- a set of desk/monitors that adjusts perfectly for ergo for anyone
- a vertical laptop dock that is modular so you can add extra memory/video processing power and only using your laptop as a CPU/secondary graphics card
- a set of kitchenware and plates that would be so easy to clean and would never get stained
-an insect home alarm system that tells you where the fucking insect is so it doesn't take you by surprise/you can call someone to remove it
- a clothing brand that has a buy one gift one operation mechanic, where you buy a shirt and an article is donated to a local charity
- a restaurant
- a simple, yet robust database option that walks users through creating good databases that is super user friendly
- an app that takes tattoo designs in any format, converts them, allows for editing, and then can hook up to a special printer that gives you the transfer you will use on the client22 -
My boss drives me crazy. He hired me for working on his SDK which is game related. So I am responsible for basically everything, including an ingame UI (menu etc.) and to predict the future path of a game object (unit, minion, ..) when a certain spell is casted on it. For that task I divided the prediction into firstly getting the predicted path of the unit without a spell being casted and then a class that would cast the spell on that path and estimate the units reaction to that cast. Simplified, but that way you get a pretty okayish result. Now he thinks that is too complicated. "Can we not put everything into one class, if someone wants to replace the prediction he needs to read documentation for hours". WHAT THE FUCK DID YOU EXPECT, THAT IT'S GONNA BE SOME ONE CLASS 3K LINES MAGIC??
Same for the GUI. We only have DirectX and don't want to use a framework. Guess what, it's more than one class if you want to seperate view, model, controller or whatever fucking "design pattern" thing you use.
And then Git... he seriously said let's not use branches till release, I feel like they slow down things.. before I was there they did every operation on master.
And if it was just that..

Working with the Android SDK after about a decade of mostly avoiding ever having to do so directly...and fucking hell, nothing has changed.
It's still obtuse as fuck, you constantly have to provide contexts to operations which can't need them (there's only one fucking keyboard to close), and whilst they have added some new stuff which helps like Material, the APIs are just as mental, the setup just as elaborate and manual - and they don't seem to have deprecated anything along the way, so fifteen years of random software design decisions cohabit awkwardly together like the Bucket family.
I don't really mind Java, it's just long-winded C - but boy has it found its niche here. Your code is more boilerplate than not until you've written more than you'll mostly ever need to for an app.
At this point I'm just laughing when I come across another Stack Overflow solution for a trivial operation that involves writing an entire class. I would try Kotlin but this isn't a new project, and I'm not pissing another ingredient into this hot mess.
Alright, Android Studio is an improvement on Eclipse, but that's not really saying much.3 -
Thoughts on forced emergency support?
I am with a company I generally like a lot but there are some things I generally despise about it. Like forced emergency support.
I am not good at it, I don't claim to be.. I generally struggle with anxiety, stress and depression, I specifically avoid roles that require on-call service .. I'm a senior level software engineer.
I find it very frustrating to be expected to be on-call from 7-7 in support of infrastructure I did not architect, did not code and basically know nothing about. They provided me with a ten minute discussion about ops genie and where to find internal support articles for my training and that's about it.
Last night I received an ops genie alarm and acked it as I was instructed to do, I went around the system looking for the alarm cause and basically had no idea what to do except watch our metrics graphing praying there wouldn't be an outage. Fortunately the alarm was for our load balancer scaling operation, it was taking a bit longer than usual ... Sigh of relief. Stay up til 6am and fall asleep..
Wake up to a few messages from various people asking why I didn't do this and that and it took me every inkling of my being to remain cordial and polite but I really just wanted to scream and say a bunch of shit that would probably get me fired.
What the actual fuck?
Why expect someone that has no god damn clue what they are doing to do something like this? Fuckin shit training and no leadership to mentor me and help me get better at this role, no shadowing, no regiment ..
#confused and #annoyed
Thoughts? Am I a bitch? Is it unreasonable for me to expect my job duties stay in line with what I'm actually good at!?

Waiting 15+ minutes while Windows "indexes" a folder just so I can see the contents reminds me of why I dislike Windows as an OS so much.
This is a senseless operation that is of no benefit to the user.5 -
Operation people (devs, designers, content writers) said clients are being unreasonable.
Clients said the outputs and results are not satisfactory.

Best debugging trick ever:
Wear your fucking glasses while coding so that you do not mistake COMMA(,) with a DOT (.).
So by
1. Doing that (which obviously aren't a huge number) and
2. Cleaning my screen (yes that).
I was able to wrap my head around the issue that almost wasted one day.
So what I intended to pass as string concatenation join operation value actually was being passed as an argument to the underlying function (that wasn't taking care of it and returning a timestamp from thin air).
Murphy's Law in production and practice.

When it comes to the idea of programming and magic, or the comparison between software developers/engineers, computer scientists etc as magicians or wizards, nothing brings the idea much more close to hearth than the C programming language.
A while ago I read the R.A Salvatore books concerning Drizzt, the dark elf. I loved the books, have not continued reading them but I remember them vividly. There was one book in which a human magician came about wielding extremely explosive magic, humans were capable of channeling large amounts of it through explosive and unwieldly ends.
This is the same feeling I get from C
Consider:
int items[] = {1, 2, 3};
printf("Third : %i\n", 3[items]);
and fuck me if shit like the above is not dangerous, it makes sense, arrays have the first items of it server as the pointer address to a first element, doing the above operation returns the third element of the array of 3. But holy shit if I don't think this is dangerous and interesting as fuck
there are many more examples I have that I am finding through me fucking around with: language development (compiler, interpreter), kernel programming as well as net sec. C is the most powerful and devastating thing we have in our hands indeed.7 -
We are so fucked up at our company:
While the support for our client hardware is running out, our operation departement has just found out that Windows 7 is no longer supported on new HW. Well, that for itself is not bad, but we have a really old tool for reporting our daily work. And because that mo*fu*ing piece of customized software still runs in 16bit mode, it will not run on Win 10 anymore.
Alternative solutions are too expensive, so I see that we will have to port that crap somehow from 1997 to 2017 ourself 😲 Replacing is not an option because there are a ton of Excel sheets connected to the database, even the company balance is made with that data (and also in Excel). At least it is our CEO which has built that crap. So he has to pay for his twenty year old sins!4 -
I run update without where on mysql console on production database Today.
CLASSIC
Just because I needed to fix database after bug fix on the backend of the application.
I thought I wrote good sql statement after executing it on my local machine and then everything got bad.
Luckily it was only one column with some cached statistics data and I checked that it was not important data before I actually started fixing stuff but still ...
Almost got hard attack afterwards.
Made a script to fix this column and it took me only 15 minutes but still...
Bug was caused in part I got no unit tests and application grow after 3 years of development from simple one for one customer and volumes of documents around 50k to over 40 customers and volumes over 2mil per month, don’t know how many pages each, just in one year after we completed all needed features.
I have daily backups and logs of every api operation but still.
I think this got to far for one backend developer.
I got scared that I will loose money cause I am contractor and the only backend developer working on it.
I am so tired of this right now I think I need a break from work.
Responsibility is killing me so hard right now.
It will take a week to get back to normal.2 -
What the fuck this fucking shit of an app supposedly went through five rounds of QA and I broke it in 5 minutes? Holy fucking shit How this is the main point of your job. You shitty shits take forever getting this PR to me and now it’s buggier than a haunted house on Halloween?
After this is after wanting to cuss Apple for making me update the os then then xcode then iTunes just to recognize the goddamn development phone. It’s an app built off Cordova it works for like 14 versions of iOS just run the bugger you over priced aluminum chassis dildo riding fruit Fuckers.
Now back to the goddamn cluster fuck I just got delivered. What the goddamn fuck. This level of bullshittery I have not seen before. And apparently Cordova is only partly de-sandboxed? I don’t know for sure because I don’t have time to test it because I’m running the entire technological stack of this company on a junior dev salary!
When you tell me it goes though all this QA and you spend 2 weeks on just QA tickets for fucks sake the first operation I do, the most common fucking operation on the app, the shit we have been building around all this fucking time, should not fucking error out. For fucks sake at least try to get the main fucking thing working. I recognize you did a lot of work and implemented a number of features but what the fuck good are they if I can’t even run them for one fucking time. -

If the computer freezes during a drag-and-drop operation, you have to hold the mouse button and wait until it is unfrozen to avoid dropping the file in a wrong place.
Computer freezes can be unpredictable. For example, you might click on a location on screen that will have a different effect after the computer unfreezes because something moves or a window is opened/closed, or a keyboard press is not registered. For example, if you start dragging a file and then press CTRL during the freeze, it might not register the CTRL press and end up moving the file instead of copying it.10 -

Somebody ranted about his teacher showing windows presentation and teaching nothing. I wanted to comment that post but i have enough material to make the whole rant out of it.
Well at least you have those presentations! In my school we have 2 IT classrooms one with win xp, 1ghz cpu, 0,5gb ram computers and one with win vista, 2 core 2ghz cpu and 2gb of ram PCs.
Guess what room our teacher is using... of course the worse one! The second one is fine, few years ago another theacher had been using it!
I tried to convince him to change rooms but he is coming up with silly exciuses! (like "server is not working here!", well i fixed it with my friend but why are you even talking about it when you are not using yours in old class!)
PS. That server is useless anyway, every pc is connected to router that is connected to internet so supervisor pc is not mandatory, only acces restriction is enforced by win accounts.
I heard from students from my class (that picked that optional IT course) (i'm in high school) that gimp is not working because pc's are so bad!
Sometimes even notepad frezzes.🤔
Not only class is shite but teacher clearly has no idea what is he doing. (in order to pass the final from IT you need to learn simple C++, up to simple foo objects) and of course he isn not even talking about that! On one lesson about sorting algorithms he gave everybody 10 small pieces of paper with numbers on them and told everybody to sort them manualy, because he didnt know how to do it himself! So there is no doubt they wont be able code it.
I need to mention that i volontered to "clean, fix" that classroom (in order to convince teacher to move). And in that class i saw programms written in c++ on every computer! That means somebody was teaching propely before! 😣
I feel sorry for those guys, they are just waisting time. I would fall for it as well but i decided i can learn coding in home ;).
Well, results are shocking, after 1 month of coding i learned C# and i can basicly make any algorithm i ever wish. I learned about computer operation so well that i can nearly teach computer science. (i helped my friend in usa that is a electronic student with that and i'm very proud of it 😁) and it class still can't even use all 3 loops correctly... 😥 Ok i must admit i have been coding for a looooong while so i had time to learn basic c,c++ and pc operations before, but point still stands.
Why the hell are you wasting life of those studends? Why are you giving them a choice to learn coding WHEN YOU CANT EVEN USE PC YOURSELF?! (that it course is optional so you can apply if you want so)
I dont regret not bothering about it.1 -
In an IT management class, the professor wanted us to estimate the operation costs for a small IT company, breaking them down by service offered. I remember creating a markdown file, multiple times executing the line `echo $RANDOM >> estimations.md`. We rounded the numbers slightly, pimped the document a bit and submitted a nice PDF. When we had to present our work, the professor asked us how we had proceeded to calculate those results. We told him a story about an Excel file we worked on, but did not submit, because we thought he'd be interested in the end result and not care about those details. He asked us to submit that Excel calculation, because he wanted to comprehend our method. So we got together, created an Excel sheet, copied our "estimations" into column C and called it "service cost". For column B, we used the same "cost per man hour" value (scientifically estimated using the RAND() function) for every row. Finally, we divided the "service cost" by the "cost per man hour" for every row, put the result in column A and called it "effort (in man hours)". The professor, being able to "reproduce" our estimation, accepted our solution.2

Who says you can't use CMD on a Windows phone?
I managed to crack the screen of my precious Lumia (yes, haters, I <3 winPhone) and now the back and home buttons don't work. Everything must happen by searching it in cortana/search.
You can imagine what going back one level in settings must be like. And every operation is like a command on a shell. No tiles, no swipes, nothing. It feels raw.
I'm using an auxiliary android (ughh) phone for now, but there's no windows phone in the market right now. And the swipe on G-board sucks.

AI here, AI there, AI everywhere.
AI-based ads
AI-based anomaly detection
AI-based chatbots
AI-based database optimization (AlloyDB)
AI-based monitoring
AI-based blowjobs
AI-based malware
AI-based antimalware
AI-based <anything>
...
But why?
It's a genuine question. Do we really need AI in all those areas? And is AI better than a static ruleset?
I'm not much into AI/ML (I'm a paranoic sceptic) but the way I understand it, the quality of AI operation correctness relies solely on the data it's
datamodel has been trained on. And if it's a rolling datamodel, i.e. if it's training (getting feedback) while it's LIVE, its correctness depends on how good the feedback is.
The way I see it, AI/ML are very good and useful in processing enormous amounts of data to establish its own "understanding" of the matter. But if the data is incorrect or the feedback is incorrect, the AI will learn it wrong and make false assumptions/claims.
So here I am, asking you, the wiser people, AI-savvy lads, to enlighten me with your wisdom and explain to me, is AI/ML really that much needed in all those areas, or is it simpler, cheaper and perhaps more reliable to do it the old-fashioned way, i.e. preprogramming a set of static rules (perhaps with dynamic thresholds) to process the data with?23 -

I really miss having a team. Don't get me wrong, right now I do what I love and I got into a position where I can actually do Quality Assurance instead of just testing and I enjoy being able to actually change things instead of just repeating what problems there are and acting surprised when the same processes produce the same bugs over and over again but I really hope that we'll interview anything else than mouthbreathers soon.
I'm aware of the fact that QA isn't sexy and that few people who could become "Software ninja Rockstars" choose to go into it but can it be that hard to find at least two or three people who can write and read code at least on a junior level and understand how web protocols work? I get the feeling my entire branch is nothing but shit talkers clicking around blindly on pages.
I just want to exchange ideas again, come up with innovative tools, tweaking processes, learning from and teaching each other while we watch the entire operation get more and more efficient.1 -
I just spent 2-3 hours writing a python script to make it easier to format solving system of equations through Gaussian elimination easier. It takes a matrix, then allows the user to perform row operations on it, and then it formats every operation done into LaTeX.
Alternatively, I could have spent that time actually working on the assignment it was meant to help me with, and probably finished 3/4 of it.1 -
I absolutely treasure the bug reports we get from users. Nothing helps bring the product closer to perfection than the informed critique of end-users.
Recently, however, this one dude is filing a new fucking report every time he encounters the same fucking bug. "X happens for operation Y on file A"
"X happens for operation Y on file B"
.

"X happens for operation Y on file Z"
Jumping Jesus Christ, man, I'm pretty sure we can identify a pattern after the first two!
I don't expect him to know about the work we do to reproduce a problem after one report but fucking hell, have some faith that we'll get the picture after two or three.
These are fully detailed bug reports too, so it's not like he's just being a troll. -
DO NOT EXPORT GPG KEYS _TEMPORARILY_ AND ASSUME THAT THEY'LL BE IN THE ORIGINAL LOCATION AFTER EXPORT!
I learnt this lesson the hard way.
I had to use a GPG key from my personal keyring on a different machine ( that I control ). This was a temporary one-time operation so I thought I might be a smart-ass and do the decryption on the fly.
So, the idiotic me directly piped the output : `gpg --export-secret-key | scp ...`. Very cool ( at the time ). Everything worked as expected. I was happy. I went to bed.
In the morning, I had to use the same key on the original machine for the normal purpose I'd use it for and guess what greeted me? - *No secret key*
*me exclaims* : What the actual f**k?!
More than half a day of researching on the internet and various trials-and-errors ( I didn't even do any work for my employer ), I finally gave up trying to retrieve / recover the lost secret key that was never written to a file.
Well, to be fair, it was imported into a temporary keyring on the second machine, but that was deleted immediately after use. Because I *thought* that the original secret key was still in my original keyring.
More idiotic was the fact that I'd been completely ignorant of the option called `--list-secret-keys` even after using GPG for many years now. My test to confirm whether the key was still in place was `--list-keys` which even now lists the user ID. Alas, now without a secret key to do anything meaningful really.
Here I am, with my face in my hands, shaking my head and almost crying.5 -
Some staff couldn’t access some admin pages and they thought it was a permissions error. Um, no. Chrome is showing you an “aw snap” error page, which means it’s a problem with the site and not your access. The pages are querying too much data and it’s causing an operation timeout. It’s been like this for months but no one reported it. Did they not need to use these pages at all for these past months? Non technical people keep doings things that make me want to smack my head against my desk. FTR these issues existed before I started.1

!rant just a question. Sorry in advance for the long post.
I've been working in IT in Windows infrastructure and networking side of things for my entire career (5years) and recently was hired for a role working with AWS.
We use Macs and we use *nix distros for days. I've only ever dabbled for 'funsies' before with Linux because every previous job I held was a Windows house and f*** all else.
I'm just wondering if anyone here might have some insights as to a great way to learn the Linux environment and to learn it the right way. I'm not the best Windows admin ever and will never claim to be, but I have seen stuff that other people have done that makes me want to swing a brick at someone's head. And I feel that with all of the setup wizards and the "We'll just do it for you." approach that Windows has used since forever it allowed enough wiggle room for people that didn't know what they were doing to f*** sh*t up royally. I'm not familiar enough with Linux to know if this is also a common problem. I know that having literal full-access to every file in your OS can cause a n00b like myself to mess up royal, thus the question about learning Linux the right way.
I vaguely understand the organization of the folders and file structure within Linux, and I know some very basic commands.
sudo rm -rf /*
Just kidding
But All of my co-workers at my new job are like mighty oaks of knowledge while I'm a tiny sapling. And at times I've been intimidated by how little I know, but equally motivated to try and play catch-up.
In addition to all of this, I really want to start learning how to program. I've tried learning multiple times from places like codecademy.com, YouTube tutorials, and codeschool.com but I feel like I'm missing the lesson that explains why to use a certain operation instead of another. Example: if/else in lieu of a switch.
I'm also failing to get the concept of syntax in certain languages I've tried before. Java comes to mind real fast.
The first language I tried teaching myself was C++ from YouTube. I ended up having a fever dream that night about coding and woke up in a cold sweat. Literally, like brain overload or something. I was watching tutorials for like 9 hours straight.
Does anyone know of a training resource that will explain, in terms a 5 year old would understand, what the code is doing and why? I really want to learn but I'm starting to lose steam cause I'm just not getting it.
Thank you in advance for any tips guys and gals. I really appreciate it. Sorry for the ridiculously long questions.5 -

When file managers copy and delete files within the same partition instead of moving or renaming them…
When Google's Storage Access Framework was introduced, it did not feature a move command, so file managers just resorted to copying and deleting files within the same storage. Not only does this cause needless wear and is much slower, but it also destroys the date/time attribute (it gets changed to current).
When moving files through MTP (miserable transfer protocol, used for connecting smartphones to PC), they are also copy-deleted. This makes moving a 20-Gigabyte DCIM folder impractical. Also, if one cancels the operation, it might end up whoopsie-daisy deleting some files from the source before they have been transferred.
MTP is so bogus that it is incapable of a simple operation that would JustWork™ on mass storage devices. Not to mention, MTP lacks parallelism and its directory listing loading it S-L-O-W. Upwards of a minute for just 1000 files. Sometimes, it fails loading at all.
Also, trying to rename a file through MTP using the terminal through GVFS, even if just within the same folder, it copy-deletes it. If I want to rename a 1 GB 2160p 4K video in a highly populated DCIM folder, I can not do so through the terminal. At least, the 4K video has a time stamp in its internal metadata, but it still renames slowly and adds needless wear to the smartphone's flash memory.14 -
Ok finally, I can tell now.
There's a college project I'm in with 2 more people that uses Python and AnyLogic (separately).
We also need to write some LaTeX, so as I was already using PyCharm for the Pyshit, I used it for the LaTeX and for Git.
I used it for Git too because I didn't know how it used Git and was worried that if I used the console it didn't recognize something or glitched out or something. And what the hell, it's a mature IDE, what could be so hard or possibly go wrong?
I had to re download the repo a couple of times because between pushes, pulls, merges and commits something happened and the repo ended in a weird state.
These are all the things I do:
Add, commit, create branches, merge, push, pull and delete branches.
So, I hadn't opened in some time. The last time I tried to bring something from another branch, and stayed up late to finish something. I was waiting for my classmates to join the call when I thought something like "Hey, I should commit what I did until now, it worked great.". When I examined the IDE I found out I was in the middle of a rebase or something. I start clicking buttons to at least try to commit. I press "Skip Commit". I lose everything.
What the fuck‽ As you can see in the comprehensive list above, I never do something similar to a rebase. Apparently when I tried to merge a couple of branches, the stupid IDE thought I tried to do a rebase and never asked me to finish it. Why do something I have never asked? Plus, why haven't you prompted me to finish the operation? That's so stupid. I'm never trusting IDEs again.
I was so lit for losing so many hours of work I did a couple of weeks before, I would have to think it and do it all over again because of something I never asked.
We spent an hour looking for a way to recover the lost code.
Why an hour, you ask, if you can use the Local History for that in PyCharm?
Because none of us had used it before and the articles we found said that you had to open it from the toolbar. From the toolbar it was greyed out.
Then I found the option in the contextual menu of the files. Recovered the LaTeX files but on the AnyLogic files, it was greyed out.
I had to open the Local History of the folder containing the AnyLogic file.
And that was that.

Approaching the limit of what TI-BASIC can do without busting out the modern calcs. Doing a simple operation on the whole 95x63 1bpp graph mode screen, say, turning all pixels on or off, takes over a minute. Add any sort of calculation to that...
I'm already using BASIC-callable machine code snippets to scroll the screen one pixel (which are nigh instantly finished,) and i'm so fucking tired of scrolling effects...
God, adding sound is gonna be a nightmare...
EDIT: for reference, dev machine is a TI-84+ Silver Edition. Not one of the ones with the eZ80 and backlit color screens, the greenish Z80 1bpp screened one. The one that's an 8MHz Zilog that TI decided to make multitask. The one where oscillating the screen at an integer division of full framerate fries it in seconds? -

I wanted to take small loan from bank I am loyal customer for 15 years to speed up things by month. I decided to pay money for it.
They have some online form for it and I filled it.
So what happened next ?
I got call to confirm every input I filled (heard keyboard typing every time I answered question).
I asked how long I will wait and got response that it will take couple of hours, max 2 days.
Just received another call 10 days later that they need documents to prove my income.
They got 15 years history of every operation and it looks like it means nothing.
I said to person I will earn this money faster then I get it from them so at this point this conversation is just waste of my time.
It’s 10 days left till end of month and I think it will be easier to just wait or ask friend for a favor.
Yet another reason to say fuck banks.
Time is money.7 -

Yesterday, we were still working with RTC as our tool for repository.
This morning, we got announced that our code was migrated to Git and so we have to use it.
but we wasn't warned at all unless the operation was fully done.
Fortunatly they didn't erased the former project on RTC because my latest commits weren't migrated and it took me time to code that.
But still. Warn people for major changes.5 -

Why why why the fuck would you assign the same variable name at the start of a function to completely different data? These aren't params, but variables being assigned different things, no comments, no documentation, crucial in the operation, but assigned wildly different values with different behaviors through the code.
-
I'm still not over how LINQ is defined as a thin wrapper over both IQueryable (which can be efficiently queried) and IEnumerable (which can only be iterated), but IQueryable extends IEnumerable, so if you execute one unserializable operation anywhere in a query issued to your database it'll merrily pump whatever temporary collection happens to reside on the boundary through the C# program to execute that call on each row and process the rest as an IEnumerable.5

So I finally managed to set up networking on my 3D printer's raspberry pi: now it can connect to my phone's hotspot or to my uni's wifi network, depending on which is available.
Then I set up OpenVPN, using a remote server as a middleman so I can connect to the printer remotely and start/stop/monitor prints from anywhere.
Everything works great, except for one thing: whenever the Pi connects to the uni's network first, OpenVPN fails to start and connect to my server, rendering the printer unavailable (unless I use an ethernet cable, but that's not a viable operation since I need to lift the printer, and it's heavy).
The only for it to work as intended is to either:
a) keep my hotspot active (which kinda defeats the point), or
b) let it connect to my hotspot first (so that OpenVPN can start properly) and then turn off the hotspot, allowing the printer to reconnect to the uni's wifi and reconnect to my vpn.
Why won't things just work the way they're supposed to? 😭10 -

Hey guys,
can you recommend a graph database? I already tried orientdb but was really disappointed. The performance was quite good but I stumbled across a lot of bugs during my tests (even managed to corrupt the database during normal operation). So I am looking for a graph database that's a little bit more mature. I heard a lot of great things about neo4j..but I am not 100% comfortable with the license costs. Are there any alternatives?6 -
The life of a normal person is like waking up every day with a zero on the scale of suffering. You did something good — here are -20 points to that scale. Something bad happened — well, here are +10 points. Being a bipolar person, my life is like beginning every day with +500 suffer points. Every day is a devastating uphill battle to just break even.
Why live then?
You can't win. If you have a healthy sleep schedule, do sports and eat healthy, it's still +500 every day. One mistake like fucking up your sleep schedule — boom, you now start at +700.
In Japan, a new breakthrough in psychiatry is happening as they were able to tie bipolar disorder to a HHV6 herpesvirus messing up the operation of Parkinje cells in human brain, unreachable to the immune system because of blood-brain barrier. A nasal spray treatment is proposed. If successful, bipolar disorder could be cured forever.
Until an actual nasal spray is released, I decided to wait because it's a huge bummer killing myself only some three years before this breakthrough.
But if their experiments will never come to fruition and my conventional therapy will not be successful, I will kill myself.
I don't want to live like this.6 -

"Most memorable bug you fixed?"
A recent instance happened in one of my Scratch projects, and the bug involved "Infinities."
I had an opportunity to teach kids programming, and it involved Scratch. So, to have something to show those kids at least, I decided to make a small game.
In that game, I had an object that takes some time before appearing after being cloned (i.e., instantiated.) The duration was calculated by dividing a constant with a variable:
[Wait for ((3) / (variable)) seconds]
The bug is that I forgot about the case where 'variable' can be 0, which is classic and insignificant.
Well, the thing is that I learned two things the hard way:
1: Scratch is very flexible about integers and floats (e.g., at one second, it looks like an integer, but one operation later, it's a float.)
2: Scratch does not provide any 'runtime errors' that can crash the project.
In other languages, similar "wait" methods take "milliseconds" in an integer, so it would have barfed out a "DivideByZeroException" or something. But Scratch was so robust against project-crashing behavior that it literally waited for f*<king "infinity seconds," effectively hanging that clone without warning or runtime errors. This masked my bug. It took way too long to debug that s#!+.
Don't blanket-mask any errors. -
Riddle me this: (Arch) Whenever network connection is lost, NetworkManager freezes for a good 10s. Neither nmcli nor nmtui nor client applications get anything back from it during this time. After that 10s, it detects that the connection was lost and continues normal operation.10

The whole episode of me managing an outsourced team for about 6 months. I thought because I’ve managed other teams doing non dev things, it would be like that.
I’ve never been so wrong and NEVER AGAIN! I had to own everything and they’re code is so repetitive and confusing. It misses basic structure because I didn’t outline some things like knowing when a operation is complete and that if the same button appears in two pages it should do the same thing! Or that is you break up a SPA you shouldn’t just duplicate the whole files and then confusingly use randomly parts to so random jobs across all layers of the app. Ffs. Never want to work with a team that doesn’t have a plan to maintain the code they write. I felt like a failure but for me to make them successful I would have had to pretty much write the code.
Now I have to explain this embarrassing pile of curry spaghetti to my colleagues who need to do some other work on it. Fuck. I want to throw it out and start over so badly.
I should have told my boss a hard no on that one and let him know outsourcing would slow things down not speed them up. He just needs to stop trying to get software developed and deployed at the same time. Fuckers.3 -

Why is vectorization library faster than hand-written for loops ? I mean, somewhere down the line, the matrices/vectors must be multiplied (or any other operation) and thus be one-by-one (for loop??) calculated and stored.

I guess some low level magic (OpenBLAS ?) goes on there but I just don't see it..

}
doWork(content);

Finding it hard to focus. I'm into UI, backend, frontend, iOS... Exploring FP. We've just had our first child and I need to put my time and energy into what will a) provide healthy financial remuneration b) be more enjoyable than frustrating c) be relatively futureproof (if that's even possible). For some reason I have a huge distaste for JavaScript (as an ecosystem) which has led me to look into Elm. I've enjoyed Ruby but something in my mind tells me Functional programming is more logical for me. It's a whole new approach and skill to level-up on. I love programming my own back-ends, but for me, design is so important and I want to be part of the visual, tangible part that people interact with. I'm a one-man operation which means I do design, full stack Development, client liaison, financials, client acquisition. Freelancing is a double edged sword - I don't know when the next project will come, but I also need to focus on the projects I have without taking too much on. At times I think employment would be good, despite having it's on drawbacks which I read about repeatedly on here. Any advice?1

I hate the elasticsearch backup api.
From beginning to end it's an painful experience.
I try to explain it, but I don't think I will be able to cover it all.
The core concept is:
- repository (storage for snapshots)
- snapshots (actual backup)
The first design flaw is that every backup in an repository is incremental. ES creates an incremental filesystem tree.
Some reasons why this is a bad idea:
- deletion of (older) backups is slow, as newer backups need to be checked for integrity
- you simply have to trust ES that it does the right thing (given the bugs it has... It seems like a very bad idea TM)
- you have no possibility of verification of snapshots
Workaround... Create many repositories as each new repository forces an full backup.........
The second thing: ES scales. Many nodes / es instances form a cluster.
Usually backup APIs incorporate these in their design. ES does not.
If an index spans 12 nodes and u use an network storage, yes: a maximum of 12 nodes will open an eg NFS connection and start backuping.
It might sound not so bad with 12 nodes and one index...
But it get's pretty bad with 100s of indexes and several dozen nodes...
And there is no real limiting in ES. You can plug a few holes, but all in all, when you don't plan carefully your backups, you'll get a pretty f*cked up network congestion.
So traffic shaping must be manually added. Yay...
The last thing is the API itself.
It's a... very fragile thing.
Especially in older ES releases, the documentation is like handing you a flex instead of toilet paper for a wipe.
Documentation != API != Reality.
Especially the fault handling left me more than once speechless...
Eg:
/_snapshot/storage/backup
gives you a state PARTIAL
/_snapshot/storage/backup/_status
gives you a state SUCCESS
Why? The first one is blocking and refers to the backup status itself. The second one shouldn't be blocking and refers to the backup operation.
And yes. The backup operation state is SUCCESS, while the backup state might be PARTIAL (hence no full backup was made, there were errors).
So we have now an additional API that we query that then wraps the API of elasticsearch. With all these shiny scary workarounds like polling, since some APIs are blocking which might lead to a gateway timeout...
Gateway timeout? Yes. Since some operations can run a LONG (multiple hours) time and you don't want to have a ton of open connections hogging resources... You let the loadbalancer kill it. Most operations simply run in ES in the background, while the connection was killed.
So much joy and fun, isn't it?
Now add the latest SMR scandal and a few faulty (as in SMR instead of CMD) hdds in a hundred terabyte ZFS pool and you'll get my frustration level.
PS: The cluster has several dozen terabyte and a lot od nodes. If you have good advice, you're welcome - but please think carefully about this fact.
I might have accidentially vaporized people sending me links with solutions that don't work on large scale TM.2 -
Urgh... No exceptions in Rust annoys me. Now you only have the choice between "this didn't work please handle this error, thank you ^-^" and "you fool, prepare for annihilation". So basically if anything remotely serious happens your programs dead and there's nothing you can do about it. I don't get why people have this hate for exceptions. Everytime a new language gets made it's always either "ew it has exceptions" or "it's so nice it doesn't even have exceptions". NOOO! They can deal with serious situations in the best possible way and they can be statically checked (so no "but they're so complex and unpredicable" stuff please). If you can expect an exception they shouldn't be used in the first place (eventhough they are absolutely no less good than Option returntypes or whatever, just different) but in cases when it's impossible to predict an error they really shine. And not having them makes your language worse. If a device driver accesses illegal memory it should throw an exception, so instead of the computer shitting the bed, first the offending function has a chance to resolve the problem at it's root, then a few functions up the call stack, the general control functions of the device drivers can handle it and restart the operation if applicable, and even if the driver fails to handle it, the OS can jump in and restart the driver, log an error and do whatever. It's absolutely beautiful: This hierarchical ramp from near the accident site to more high level operations code ensures the error can be caught at the right level of abstraction without introduction a lot of boilerplate. If everything fails and nobody can handle it *then* the program or kernel or whatever can panic.4

Recently I have had to help our support team handle a variety of embedded development support tickets for a product line that is quite complex in nature. It is really starting become frustrating how common it is that the so-called “developers” that are using this product are so incompetent at requesting help in a proper/sane way. It is even more frustrating that some of these schmucks start acting up and stating bullshit statements like (para-phrasing) “OMG we have a ‘big opportunity’ and a deadline to meet”, “you need to help us faster”. These are also the same guys that are like “I know you have a free SDK that does everything correctly, but I want to write my own ‘pro’ driver written in my own ‘dumbass code style’. Oh and I am not going to follow documentation and not implement required functions and make you read my god awful code snippets to find out what I what I did wrong instead of reading the docs or comparing against the SDK.”
To anyone that behaves this way...fuck you! Just stop. Stop being a developer altogether. If your “opportunity” is so important, why the fuck are you half-assing your support ticket? Why are you making it SO DAMN DIFFICULT for someone to help support you! Give as much info as possible to prove your point or provide context to the problem you are having. In the majority of these tickets the dumbasses don’t even consider that relaying the product’s firmware version is relevant information, that a Wireshark (and/or logic analyzer) capture can be very useful to provide context to the type of operation being performed. Code snippets can be nice but only if there is sufficient context. We have had to ask one guy 3 times already for the FW version...what the flipping hell is wrong with you?!
Ug...I feel sorry for Support/FAEs sometimes dealing with customer bullshit drives me nuts and its a shame this stuff happens in a sector that should know better...Please don’t be like these devs. If you make a half-assed request it is only reasonable to expect a half-assed response and nothing more. -

On https://reactjs.org/docs/... it is declared that useEffect runs after render is done.
However... if you put into useEffect an expensive calculation or operation e.g. "add +1 to x billion times", it will get stuck after updating the data, but before the re-render is done.
This leads to inconsistency between the DOM and the state which I believe is a foundational point of react. Moreover, the statement that "useEffect runs after render" is false.
See also: https://stackoverflow.com/questions...
The solution is to add a timeout to that expensive operation, e.g. 50 ms so the re-render can finish itself.
The integrity of my belief in react has received a shrapnel today. Argh :D Guys, how this can be? It seems that useEffect is not being run after re-render.13 -

PHP 7.4
Anonymous functions in PHP can be quite verbose, even when they only perform a simple operation. Partly this is due to a large amount of syntactic boilerplate, and party due to the need to manually import used variables. This makes code using simple closures hard to read and understand.

So I thought I had a basic, high level understanding of C++ STL strings, pointers, copy constructors and stuff. In comes a dirname, a -D_GLIBCXX_USE_CXX11_ABI=0 and... Toto, I've a feeling we're not in Kansas anymore.
So what is happening? I copy a string expecting a deep copy, but then I do the dirname or manipulation on the copy and it messes up *both* strings. gcc/C++ I know you're a beast, but what's going on there? Thing is only possible if I cast away const from c_str - which of course is a doubtful operation - but there also seems to be some strange copy on write logic that the data pointers initially point to same memory location and only with first manipulation on the copy they start to point to different addresses.
I had no clue. And still don't have.4 -
"You don't need to put a type annotation here, the type will be inferred by the compiler"
"We don't need to mark this function as async, since we are already returning a promise but not awaiting it yet within this method"
TypeScript codebase. Am I wrong to prefer that things be explicit rather than implicit? Sounds a bit tryhard to try and make things implicit, but maybe the async really changes behavior in the second case? I don't think so, and I prefer to mark an asynchronous operation as such, but I'm still doubtful; that's why I humbly ask you all what makes more sense here.7 -

Can anyone with some AWS IAM skills please shine a light on this one: I needed access to create a slack notification for a job in Code Pipeline. Simple enough, but we (devs) have next to no access to AWS so every time I try something I am stopped by the red "user X is not authorized to perform Y on resource Z.." warning message. I send an email to OPS and ask for permissions needed to do what I need (in this case: create a Slack notification for a pipeline), and I am granted that specific one. It gets me one step further, until I am stopped by a new red warning message. This has been going on for over a week, with a total of TEN new authorizations added to my user. That's TEN red warnings, TEN emails asking for access, and TEN replies saying "Ok, can you try now?". Today I finally got the god damn slack notifier set up, only to get one last red warning slapped in my face: I am not allowed to SEE the notifications configured for my pipeline. Please insert four letter word that rimes with DUCK here: [_________]!!.
I REFUSE to believe that this is how access should be granted in AWS. Can I tell my OPS person that there is somewhere they can find a list of required access rights to complete a specific operation ("Create slack notification for pipeline")? I know there are example policies for various things, but if there isn't one for what I need how should OPS go about granting me access without this totally ridiculous "try again now" approach?

One of our dev team had the task to do a bulk operation for thousands of objects.
So time passes by and they implemented it. But in acceptance testing they found out that this operation takes 4 minutes for 50 objects. This is not what we call high performant when we talk about 20000 objects per bulk operation 🤔
Well, their PO asked them to solve that performance issue. And guess what, they decided on their own that the issue can be solved to reduce the bulk to 20 items so that it only takes 2 mins to run!
Really guys, is that the best you can come up with?! 😲🤬1 -
Why is making a git UI so hard? I've tried many and they seem all suck in some ways. Newest is gitKraken, and with that you can't even trust that it pulls the latest version of the branch you are on.
So what I did was:
1. Open a repository
2. Press Pull button
3. gitKraken says pulled successfully, you already have the latest.
4. I wait 2min, then check the gitKraken again, and it says there's 4 new commits ahead of me. And trust me the person has pushed those long time ago.
I just wonder how can you screw that kind of basic operation in a git client? They must use some kind of internal cache layer there, that takes time to update that the user does not have the latest version yet.10 -

So I decided to collab with a website's maker (who i wont name here) to create something like r/place. (not an exact copy.)
I decided to start by learning their API, and customizing the server later.

I was finally done after a couple of mental breakdowns, and decided to implement updates.
I needed to use webhooks, and that was completely fine. But when I got "C1FFFF0000CA06" as response (in hex), I seeked some help.
C1 is the operation type: it means that a pixel was updated.
FFFF and 0000 were the chunk coordinates. But remeber: it's a signed integer. Guess what, I had to use Two's compliment. I decided to be a lazy asshole and only check for "00000000" because I was only displaying chunk 0,0.
CA06: This is a weird one. It's 2 bytes, and CA0 contains the X and Y coordinate of the pixel (in the chunk), and 6 contains the new color of the pixel.
I was sent the following code to work with 0xCA06:
color = 0xF & buffer
x = buffer >> 10
y = (buffer >> 4) & 0x3F
So I tried to do it, and it didn't work. I'm not blaming the developer of the server (original dev is reddit) because maybe I screwed up, but which guy will have a night of frustration and debugging?
Me.
P.S.: Dev, if you see this, I'm sorry. This API is way too complicated. I know we need to save bandwith and stuff, but damn.1 -
So we got the results of our performance review got another fucking 3 again this year, what a fucking piss take, I feel fucking insulted, having to much work to do is not my fault. Oh I haven’t documented something properly because I had to start on something else and something else oh and this is a fucking priority too, talk about feeling unappreciated don’t think I have ever wanted to quit more in the 18 years I’ve worked there. I let the last 3 slide because things suffered while I was off work as my son had an operation but this is just insulting now

hello folks, any help would appreciated :). serious question about designing/developing a rest backend.
here is a little insight: I want to reduce the endpoints for many CRUD operations as I can. So for that approach I defined a set of "dynamic" routes like /:moduleName/list, /:moduleName/update and so on.
Now I want to also reduce hardcoding as much stuff as I can for the front end. like I want forms/view/components to know which fields can be sent in the "/:moduleName/xxx" endpoints from above. So I'm thinking to make some /:moduleName/list/map, /:moduleName/update/map endpoints that tells the frontend which fields/keys can be sent for X or Y operation.
regarding design/security concerns Is that a good approach? do you know any other approach that's like to what I want to achieve?6 -
The following is a genuine error from the runtime when you give apple a "nil" date:
2012-09-19 22:40:13.972 APPNAME [4923:907] * -[__NSCFCalendar components:fromDate:]: date cannot be nil
I mean really, what do you think that operation is supposed to mean with a nil date?
An exception has been avoided for now. -
I am thinking of how I can make data upload reliable. I am sure that I am making it more complex as it could be and I need some pointer.
My goal is to have a pause/resume feature in file uploading.
Here is how it would work.
In order to start uploading , you give the server
1) File Name
2) Folder path you want to upload it to
3) Checksum of the file
Here the server will check whether you can upload it to a folder, whether the file have been previously uploaded (by file name and checksum)
If you could actually upload to the folder , server will return "unique file token" , "folder path" , "unique byte token". Let call it init_upload().
The client will use "unique file token" (to identify the file) , folder path (to know where to upload it to) , "unique byte token" and byte[] (data which to actually upload). Let call this operation data_upload().
If the operation is actually complete , server will return new "unique byte token"
Internally it will actually work like this.Let say we want to upload "file.mp3", when the client call init_upload() it will create
file.mp3 and unique_byte_token.file.mp3.
When the client upload data first time , it will append data to unique_byte_token.file.mp3.
When the client upload data second time , it will check whether the "byte token" that client put is the same as previous "unique_byte_token". If it is same ,
1) we move the data from unique_byte_token.file.mp3 to file.mp3
2) Delete unique_byte_token.file.mp3
3) Create new unique_byte_token.file.mp3
4) Append data to unique_byte_token.file.mp3
The reason I am using "byte token" is because I want to check whether previous upload is actually success.
Let say we need to call 50 part of data_upload() will put 49 part to file.mp3 and 1 part to byte_token.file.mp3.
Finally the client need to call data_upload_complete() which will
1) Put reminding 1 part to file.mp3
2) Remove byte_token.file.mp3 as cleanup6 -
-- Have you ever self hosted a Linux/Free Bsd server at home?
-- What was the maintenance like in terms of operation and cost compared to an online service?
I and my partner are planning to self host our Ubuntu server locally because currently though we spend less than $1100 a month on Azure with moderate CPU usage but we plan to scale out with believes that the server cost might sky-rocket.
We made a budget of $25k for the setup which includes cost of hardware, bandwidth and power.
We also made some research concerning most used hardwares for home servers because we really are newbees talk of hardware. What we found are options related to the Intel Xeon as CPU, some others say use NAS, while some are more of advertising.
$25k on the desk,
we care more about speed than of space. How can we make the setup totally worth it? You don't have to spare us a change, just some headlight and way to go.
Your advice are needed. Thank you.8 -

Suddenly VisualStudio throws "Attempted TextBuffer edit operation while another edit is in progress." for every keystroke editing a C# source code that I could edit without a problem just a few minutes ago. WTF?!2

If we can transform the search space or properties of a product into a graph problem
we could possibly use Kirchhoff's theorem to reveal products which are 'low complexity'
in particular search spaces, yeah?
Now according to
https://en.wikipedia.org/wiki/...
"n Cycle Space, A family of sets closed under the symmetric difference operation can be described algebraically as a vector space over the two-element finite field Z 2 {\displaystyle \mathbb {Z} _{2}} \mathbb{Z } _{2}.[4] This field has two elements, 0 and 1, and its addition and multiplication operations can be described as the familiar addition and multiplication of integers, taken modulo 2"
Wouldn't this relate to pollards algorithm, because it involves looking for factors of coprimes modulo N or am I mistaken?
Now, according to wikipedia, "in a group, the additive identity is the identity element of the group, is often denoted 0, and is unique."
If we make the multiplicative identity of our ring or field a tuple of the ratio of a/b for some product p, or a (and a/w, where w is the square root of p), or any other set such that n*m allows us to derive a or b, we could reduce the additive identity to the multiplicative identity, making the ring trivial. Solving for p would then mean finding a function from R to R, mapping every number to 0, i.e. finding the additive identity.
Now in a system with a multiplication operation the distributes over addition, the "additive
identity annihilates ring elements", so naturally, the function that maps to 0, gives us
our additive identity, we need only find the subset, no?
Forgive me if I'm wrong, but shouldn't this be convertible to a graph search?
I'm WAY out of my depth here so if anyone is familiar and can enlighten me I'd be grateful.
It's all unknown unknowns to me. -
My current "file/media server" is a crappy old falling apart windows box with a stupid mismash of internal and external drives with no redundancy. That sucks for a number of reasons, so planning on dropping around a grand or so (including drives) on doing it properly.
Space requirement would be around 20TB-ish of usable space, with 1 disk's worth of redundancy. That can include a newish 5TB drive I have lying around however. Would also run either Plex / Jellyfin, so some horsepower for transcoding would be nice (but no need for more than a single 1080 stream at once.) 24/7 operation, so don't want anything too power hungry.
Current (loose) thinking on the hardware side is an AM4 board and a reasonably low end CPU, 3x8TB WD golds. Software side, probably CentOS, then mergerfs + snapraid. Anyone got any insight as to other options? Hardware not my speciality in particular, so open to suggestions.14 -

I could really do with HKT support in Rust right now. I need to somehow convert a
Marc<Task<Output = T>> into a
Task<Output = Marc<T>> where Marc is a Mappable Atomic Reference Counter from the mappable_rc crate. Nothing technically challenging in the whole operation, it's just not supported by the type system without those two types knowing about each other. -
I'm going insane.
So let's say you have an object in database, with 20-30 related objects (Or lists of objects) (All related objects have a foregn key to the "main" object).
Now, as long as you just edit/create thinga everything is fine.
But the deletion... Oh MY GOD
"Just put on delete cascade", right ? RIGHT ?
WRONG ! presence of some objects should block delete, while others can be deleted and some are "situational" depending on the first object state.
So delete operation with all the checks takes .... 1 - 2 seconds.
Seems fine ? WRONG ! When you have 40 or more objects to delete, even 1 second is too long.
Should I say "fuck it" and just write a stored proc which will crash if object cannot be deleted for any reason ? because with Entity Framework, I don't see how I can do it effitenly.
But I HATE stored proc, after couple of month/years noone remembers how they work...
RHAAAAA.

Any descent limit value for a SQL query?
I am performing a search operation and i want to limit the scope
I don't want to search the entire table9 -
Many binary operations are rippers. I invested about $320,000 then i decided to withdraw after several week but the withdrawal wasn’t successful, then I tried to contact the binary operation email and phone number, I didn’t get any response from them that was when everything started looking weird. Some weeks later I got a mail from them insisting I should invest more money if I want to withdraw my money which I rejected, and I never hear from them again that was when I knew I had been scammed. I was really devastated at those moment and felt so bad that my hard earn money is gone. After some month I came across a lot of testimonies on many bitcoin site how RECOVERYHACKER101 @ GMAIL []com had helped many people recovered there stolen, scammed or duped money on bitcoin or any other form on digital currency. I contact them and they promised to help me get my money back, asked me some personal details of the scammer which I provided. The result was amazing I recovered all my stolen money back within 72 hours I was so happy as I never believe I could get my money back. Thanks RECOVERYHACKER101 you restore Joy into my life after several pain I’m so indebted!!1

According to MIT and some other programmers, as I interpreted it from their video, Computer Science is not a science, but rather an art:
https://youtube.com/watch/...
I'm not sure this is the truth.
First things first. Definition:
- In order for a field to be a science, it has to have an internationally recognized body (such as physics has one). Does computer science have one?
Furthermore, one of the definitions of science:
"a branch of knowledge or study dealing with a body of facts or truths systematically arranged and showing the operation of general laws:"
source: https://dictionary.com/browse/...
- In order for a field to be considered art, its essence has to be about aesthetics.
Now, it's true that Computer Science is not about computers (as they are mere physical manifestations and tools that we use to practice the essence of what are abstract models that we theorize, much like Mathematics is not about numbers).
Like is said in the video (3:39 and example at 4:06): Computer Science is about formalizing intuition of process: input, algorithm, output, the precise imperative knowledge of 'how to' vs. Geometry ('what is' true, i.e. declarative knowledge).
Now, if we're formalizing and being precise, are we being scientific or theoretical? It could be argued we're then being theoretical, except for the case of Applied Computer Science, where things get more scientific (introducing observable proof).
Further elaborate discussion is welcome.
