Toilets and race conditions!

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

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

Him: yeah. And with a single thread?

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

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

Me: exactly!

Developers sound like psychotic sewing serial killers.

Always taking about strings and threads or killing parents, children and detaching heads.

Painfully true...

So I was hired about 4 months or so in this companty, we will name it 'Derp & Co.'

The first task they want me to do was to 'clean' an android app that, for what they told me:

- Previous dev fired. said that tasks have been done but totally a lie.
- Took a fully week of 2 fellows coworkers to 'undo' the mess.
- And for the last but not least, zero documentation, like ZERO.

So, I clone the repo, install android studio, blah blah blah, get hands to the pile of code and jesus...

- The whole app was working with a gargantuan json, there was no use of POJOs at all. Objects are for normies.
- A masive copy/paste code, like 'I will need this here, crtl-c... ctrl-v, DONE!'
- Threads are free, isn't it? let's just put a thread whenever I desire to make an HTTP request and not reuse code at all.

So... with this on mind, my first task is to make proper objects:
- Coworker: 'Sorry dev, we don't have documentation for this, you must debug the code to se what the server will send to you'.
- Me: 'Real?'

Shit... ok. So I first try to figure out how the hell is made my gargantuan json. A month was entirely lost to unravel this data and implement Objects, improve their code, reuse code, etc. but at the very end:

- coworker: 'Good job dev, when the POJOs are done, we can focus on the next task, whe have to define a new DATA MODEL because the one we are using now is not good at all'.

*note: the app is on production and working with all the previous 'features' and today it still on use on some enviroments.

- Me: 'Wait... this is a joke, now you want to define new data models? This should have been done in first place!' <WTF face>
- Coworker: 'I don't think so dev, Mr. boss have this list with things to improve on the app an this is the order of do the tasks'.

Mr. boss is on vacations, two days after he came back:

- Mr boss: 'Coworker said that you have been working with POJOs, is that right?'
- Me: 'Yes'
- Mr boss: 'Why? Did not see the need of a new data model?'
- Me: 'I told that to him, but he insist on "the order" of the list.
- Mr. boss <facepalm>

This is one of the few tales i have from 'Derp & Co.'

PS: Sorry if i made a mistake on writing, english is not my first language and maybe I have done some mistakes.

So, there was this person I met on the internet who was preaching about how the success of games depends primarily on luck.
His argument was that even though he made a great game(his opinion) and uploaded it to the appstore his game failed to gain popularity.
He stated that there are about 500 games uploaded daily and it is only the matter of luck whether or not a game gets noticed and that he ran out of luck.
Now, his game was a pretty ripped off copy of the overused tile matching games. I pointed out to him that the reason his game didn't do well was probably because he made a ripoff(I actually used 'a copy's but 'ripoff' sounds more rant like) and that he priced it fairly high, while there were free games with more features and better graphics and mechanics(based on the description of the game and screenshots).
He then began to rage(all caps obviously) about how I am talking out of my ass and that I probably haven't even made a game yet.
I politely(the only reason I was polite was because the account was known to my Twitter followers. Sometimes one has to protect one's name) told him that I am an indie game developer and that I have made a decent amount of games.
He then proceeded to mock me and dared me to name a few.
So I posted four links to my 48 hour competition games and one to an official game.
He then began to call me an imposter, so I did a shout-out to him through my Twitter account.
Instead of continuing on Twitter, he ran back to the forum, and began to shit talk about how anyone can do it if they have a team with them.
I corrected him on that, stating how I was alone at the time and these particular games were the results of me working hard and striving to improve myself.
Then the guy finally starts spamming on different threads about how I am an arrogant bastard and other explicit forms of abuses before finally getting banned.
Sometimes I don't even know why I bother.
When I was starting out, there was this developer who would point out the faults in my games so that I could work on them. That was a great help and probably accelerated my growth. He was a great mentor and is now a good friend and is now in my team.
I guess some people are so hung up on their pride that they will refuse to accept their mistakes and make any efforts to improve.

Internet Download Manager costs about $24. It's not cross platform either. uGet UI looks old as fuck and shows positive in virustotal.

So I decided to do what most other devs would do in my situtation. I created my own download manager in QT 💪. It uses 16 different threads to download files and pretty much utilises all my bandwidth.

Quick recap of my last two weeks: 15 year old production server is basically dead, boss has taken over calls and claims credit for "resolving" outages (even though my coworker and I did the work, but ultimately the traffic died down enough to where it wasn't an issue anymore).

I go to a meeting to plan migration to a better server, boss bitches about not getting invited, I tell him I invited myself, and then he lectures about how that's not our job.

Different boss says we're migrating a schema for an application that should have been decommissioned 5+ years ago to use as a baseline. I explain what's going on, he says he understands, and proceeds to tell higher bosses it's perfect because there will be no user impact. OF COURSE THERE'S NO FRICKING IMPACT, YA DUNCE! there are no users!!!!

I merge two email threads together, since they discuss the same thing, but with different insight, and get yelled at, even though they requested it.

The two bosses I like are OOO for the next week, too, so I'm just sitting here hoping I don't say something that'll get me fired or sent to sensitivity training.

I'm just starting my on call rotation and don't know that I can do this. I cry when my phone rings, now, because I experience physical pain with how hard I cringe.

I got yelled at today by a guy because SOMEONE I DON'T KNOW assigned a ticket to him directly, rather than to the proper team (not his team). So I had to look into that, which at least had the benefit of preventing a catastrophic outage to our customers world wide, but no one will know because I don't brag at work; I'm too busy doing my job as well as most of my division/section/larger team, whatever the hell it's called. I saved us probably 25+ hours of continuous troubleshooting call from noticing something tiny that the people "smarter" than me missed.

As a Java developer, reasons to kill other programmers:

- static mutable variables
- WRITING to static mutable variables
- API call with Framework X didn't work. Add Framework Y along with X and try that. Wrap X in try/catch statement. Catch block fires framework Y.
- six, seven, ten levels of nested code. Zero thought put in organization
- 6K LOC Java files
- spring (singleton? Maybe) object assigning values in static mutable (see pt.1)
- a couple of unit tests in code base that no longer work. Zero unit tests in new code
- unit testing disabled in CI pipeline
- empty catch blocks
- pass mutable data between threads. Modify in various places concurrently.

Parent threads watching over their children ones

We've seen the 'battlestations' threads more than enough, how about a server/nas/network thread?

Here is mine tucked away in an otherwise useless part of my studie.

A Developer is desperate: his java application servers are unresponsive, thousand of dead zombie threads are sucking all cpus, memory is leaking everywhere, garbage collector has gone crazy, the cluster sessions are fucked....

The Developer goes to the closest bridge, ties a stone to his neck and gets ready to jump.

Suddenly a bearded old man with a fiery look runs toward him, yelling:
- stop stop!!!! Your application is not scaling and misconfigured, your servers are melting, cpu usage is not sustainable anymore, but don't despair

The Developer, puzzled, looks at him:
-I've never seen you...how do you know...
- Hey, man, I'm the Devil. I know everything. All your problems are solved. I'll give you magic functions. They are called Lambda.
You'll never have to worry about your servers, scalability, security, configuration and shit.

The Developer seems astonished but relieved:
- Ok, sounds great! let's try it - suddenly suspicion creeps in - hmmmm but you are the Devil....so...you want something back, don't you?
(the Devil nods lightly with a diabolic smile)
- ...and...you want my soul, I guess...
- your soul??? come on!!! - the Devil burst in a laugh - we are in 2019. I don't care about your soul. I want your ass.
- What!???!!!?
- yes, I want to fuck your ass

The Developer, evaluates quickly the situation.
Few moments of pain or slight discomfort (?) in exchange for magic lambda. It could be worth. He accepts.

After a while of rough anal fucking, the devil asks
- Hey, how old are you anyway?
- 45, why?
- Oh jeeez...45!!!??? and you still believe in the devil?

Yesterday the web site started logging an exception “A task was canceled” when making a http call using the .Net HTTPClient class (site calling a REST service).

Emails back n’ forth ..blaming the database…blaming the network..then a senior web developer blamed the logging (the system I’m responsible for).

Under the hood, the logger is sending the exception data to another REST service (which sends emails, generates reports etc.) which I had to quickly re-direct the discussion because if we’re seeing the exception email, the logging didn’t cause the exception, it’s just reporting it. Felt a little sad having to explain it to other IT professionals, but everyone seemed to agree and focused on the server resources.

Last night I get a call about the exceptions occurring again in much larger numbers (from 100 to over 5,000 within a few minutes). I log in, add myself to the large skype group chat going on just to catch the same senior web developer say …
“Here is the APM data that shows logging is causing the http tasks to get canceled.”

FRACK!

Me: “No, that data just shows the logging http traffic of the exception. The exception is occurring before any logging is executed. The task is either being canceled due to a network time out or IIS is running out of threads. The web site is failing to execute the http call to the REST service.”

Several other devs, DBAs, and network admins agree.

The errors only lasted a couple of minutes (exactly 2 minutes, which seemed odd), so everyone agrees to dig into the data further in the morning.

This morning I login to my computer to discover the error(s) occurred again at 6:20AM and an email from the senior web developer saying we (my mgr, her mgr, network admins, DBAs, etc) need to discuss changes to the logging system to prevent this problem from negatively affecting the customer experience...blah blah blah.

FRACKing female dog!

Good news is we never had the meeting. When the senior web dev manager came in, he cancelled the meeting.

Turned out to be a hiccup in a domain controller causing the servers to lose their connection to each other for 2 minutes (1-minute timeout, 1 minute to fully re-sync). The exact two-minute burst of errors explained (and proven via wireshark).

People and their petty office politics piss me off.

Most satisfying bug I've fixed?

Fixed a n+1 issue with a web service retrieving price information. I initially wrote the service, but it was taken over by a couple of 'world class' monday-morning-quarterbacks.
The "Worst code I've ever seen" ... "I can't believe this crap compiles" types that never met anyone else's code that was any good.

After a few months (yes months) and heavy refactoring, the service still returned price information for a product. Pass the service a list of product numbers, service returns the price, availability, etc, that was it.

After a very proud and boisterous deployment, over the next couple of days the service seemed to get slower and slower. DBAs started to complain that the service was causing unusually high wait times, locks, and CPU spikes causing problems for other applications. The usual finger pointing began which ended up with "If PaperTrail had written the service 'correctly' the first time, we wouldn't be in this mess."

Only mattered that I initially wrote the service and no one seemed to care about the two geniuses that took months changing the code.

The dev manager was able to justify a complete re-write of the service using 'proper development methodologies' including budgeting devs, DBAs, server resources, etc..etc. with a projected year+ completion date.

My 'BS Meter' goes off, so I open up the code, maybe 5 minutes...tada...found it. The corresponding stored procedure accepts a list of product numbers and a price type (1=Retail, 2=Dealer, and so on). If you pass 0, the stored procedure returns all the prices.
Code basically looked like this..

public List<Prices> GetPrices(List<Product> products, int priceTypeId)
{
foreach (var item in products)
{
List<int> productIdsParameter = new List<int>();
productIdsParameter.Add(item.ProductID);
List<Price> prices = dataProvider.GetPrices(productIdsParameter, 0);
foreach (var price in prices)
{
if (price.PriceTypeID == priceTypeId)
{
prices = dataProvider.GetPrices(productIdsParameter, price.PriceTypeID);
return prices;
}
* Omitting the other 'WTF?' code to handle the zero price type
}
}
}

I removed the double stored procedure call, updated the method signature to only accept the list of product numbers (which it was before the 'major refactor'), deployed the service to dev (the issue was reproducible in our dev environment) and had the DBA monitor.

The two devs and the manager are grumbling and mocking the changes (they never looked, they assumed I wrote some threading monstrosity) then the DBA walks up..

DBA: "We're good. You hit the database pretty hard and the CPU never moved. Execution plans, locks, all good to go."
<dba starts to walk away>
DevMgr: "No fucking way! Putting that code in a thread wouldn't have fix it"
Me: "Um, I didn't use threads"
Dev1: "You had to. There was no way you made that code run faster without threads"
Dev2: "It runs fine in dev, but there is no way that level of threading will work in production with thousands of requests. I've got unit tests that prove our design is perfect."
Me: "I looked at what the code was doing and removed what it shouldn't be doing. That's it."
DBA: "If the database is happy with the changes, I'm happy. Good job. Get that service deployed tomorrow and lets move on"
Me: "You'll remove the recommendation for a complete re-write of the service?"
DevMgr: "Hell no! The re-write moves forward. This, whatever you did, changes nothing."
DBA: "Hell yes it does!! I've got too much on my plate already to play babysitter with you assholes. I'm done and no one on my team will waste any more time on this. Am I clear?"

Seeing the dev manager face turn red and the other two devs look completely dumbfounded was the most satisfying bug I've fixed.

I would kill all these +1 guys, srsly. I subscribe these threads to know if it will be implemented.

You do not add any value to issue:
* devs are pissed off as this does not help solving problem
* others are pissed off

No one really cares about your likes, really.

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.

Functional Programming. Because Moores Law has moved from making processors faster to multiplying cores, and we may eventually have to code on machines that have 1024 cores or more. Mutable state will cause all kinds of hell in those scenarios. We already have problems with it when we have like 2-3 different threads.

Dev: This could be sooooo easily optimized...

Me: Uhm. Don't think so. What's your idea?

Dev: Just use threads.

Me: Nope. Problem requires 3 shared resources per process step, it won't be faster by threading. Shared resource will only lead to locking contention, decreasing performance.

Dev: I don't think that will happen. Can you PROOF to ME that this will happen?

Me: It was your suggestion, so you should proof me wrong. Nice try, but no thanks.

Dev: Yeah, but it's too slow and it should run faster.

Me: If you cannot find a better approach than the current one, it runs as fast as it can while providing correct results. That's not slow. That's just working as intended and designed.

Dev: Yeah, but it's still slow.

....

You know these conversations where you just wanna rip some people's face off, stick it in the shit hole they use to talk and toss them out of the window....

Yeah. Had those conversations today.

*part rant part developers are the best people in the world*

years back a friend got a job at some non profit, as a program coordinator, and his first task was to "coordinate" the work on creating the new website for the organisation. current website they had was a monster built on some custom cms, 7 languages, 5 years of almost dayly content updates, etc. so he asked me if i would took the job of creating a new website on wordpress. i wasn t really keen on doing it, but he is a good friend so i said ok. i wrote down the SOW, which clearly stated that i will not be responsible for migrating the old content to the new website. i had experience working with non it clients, and made sure everyone understood the SOW before the contract was signed. everyone was ok with it. after three weeks my job was done, all milestones and requirenments were met. peechy! and then all hell breaks loose when the president of the organisation (the most evil person i ve met in my life) told my friend that she expects me to migrate the content as well. he tried explaining her that that was not agreed, that it will cost extra, etc. but she didn t want to hear any of that. despite the fact that she was a part of the entire SOW creation process, because she is a micro managing bitch. in any other situation i wouldn t budge, because we have the contract and i kept all the paper trail, but since my friends job was on the line i agreed to do it. my SQL knowldge at the time, and even now, was very rudimentary, the db organisation of their cms was confusing as fuck... so i took two days of searching tutorials and SO threads and was doing ok, until i got to a problem i couldn t solve on my own. i posted the issue on SO and some guy asked for some clarifications, and we went back and forth, and decided to move to chat. while chatting with him i realised that there was not a chance for me to do all the work in few days without a lot of errors so i offered him to do it for a fee. he agreed. i asked him for his rate, he said if this is a community work i will do it for free, but if it is commercial i will charge the standard rate, 50$/hr. i told him it was commercial, and agreed to his rate. i asked him if he needed an advance payment, he said no need, you ll pay me when the job is done. i sent him the db dumps, after two days he sent me the csv, i checked it, all was good and wired him the money.
now compare this work relatioship with the relatioship with that bitch from the non profit.
* we met online, on a semi-anonymous forum, this guys profile was empty
* he trusted me enough to say that he would do it for free if i wasn t payed either
* i wasn t an asshole to take advantage of that trust
* he did the work without the advance payment
* i payed him the moment i verified the work

faith in humanity restored

"ChatGPT passed an interview for Google"
"I ask to ChatGPT to write my new song"
"What ChatGPT tells about our humanity"
"ChatGPT pooped its pants"

I'm the only one sick of seeing articles, posts and threads about Chat fucking GPT?! I can't wait for the hype to die out... or for someone to build a time machine able to bring me back to 2009

Yesterday, after six months of work, a small side project ran to completion, a search engine written in django.

It's a thing of beauty, which took many trials, including discovering utf8 in mysql isn't the full utf8 spec, dealing with files that have wrong date metadata, or even none at all, a new it backup policy that stores backups along side real data.

Nevertheless, it is a pretty complete product. Beaming with pride I began to get myself a drink, and collapsed onto the floor, this caused me to accidentally hibernate my computer, which interrupted the network connection, which in turn caused an OSError exception in one of my threads, which caused a critical part of code not to run, which left a thread suspended, doing nothing.

From the floor I looked at my error and realised my hubris and meditated on my assumptions that in theory nothing should interrupt a specific block of code, but in reality something might, like someone falling over...

Some people, when confronted with a problem, think, "I know, I'll use threads" – and then two they hav erpoblems.

I'm working on a programming language with a "bytecode" interpreter and a compiler that translates source code to said bytecode and... it sort of actually works!

I want to recreate an Erlang-style environment, currently you can write functions, call C++ functions via wrappers, have immutable-only values, and it has no explicit control structure apart from statement sequencing and the if-expression because I want to make it as functional as possible. Next thing on the list is to add a green threads implementation and ability to spawn and send messages to processes.

Still a WIP and heck even design-in-progress.

Now for the rant:
I'm using CMake for building C++ (interpreter) and Stack for Haskell (compiler) and I've been trying to get them to talk to each other for hours because I want CMake to manage the Stack build too and shove all the executables into one place. CMake documentation is weird and Stack isn't too helpful either, so I guess I'll just spend another few hours trying to get Stack to fuckin reveal its build directory to CMake and/or build to a given directory. Ugh.

noob misconception #378: during my first internship the summer after my freshman year, i was under the impression that if i used 1000 threads, my job would finish 1000 times faster. needless to say, my machine crashed in a second, and my manager thought i was an idiot when i was surprised it didn't work

As a human being, you're multithreaded. You can type with multiple fingers, you can drive and hold a conversation at the same time. The only blocking function we have to deal with is sneezing, where all current activity must be suspended for the duration of the sneeze. That's pretty annoying, especially when you're driving and trying to hold a conversation. You don't want to write code that's sneezy.

Longest Rant I've written so far.

How to manage a school (by out school director):

Did this student do something spezial to emphasize the school?
-No: Ignore him
-Yes: Did the student achieve this with the help of this schools staff?
-No: Take all the credit
-Yes: Hahaha, just a joke, nobody receives help from the school. Goto -No

Q: Should this class get the 5 day trip, they've been waiting for the whole year?
Director: No.
Q: But they don't even participate in other trips just to go there.
D: No
(Good thing she did not have the last word there)

Does the school director need this one week trip to india, just to talk once about stuff, you can talk about via email, to a sponsor?
D: "Of course I deserve it"

D: "We need faster internet in this school"
Network admins: "But it won't be of any use, if the network can't handle it. We'll need better pcs (and network conponents) on top of that"
D: "No, bot enough money available for that one." *browses email with IPad paid by school money*

Teacher: "I want to realize project xy with the students. We'll need around 1200€ (for 20 people)."
D: "Can place xy at our school to as advertise?"
T: "No, but it's be a valuable le-"
D: "600 at most."
(Again denied by people who aren't fcking assholes. We got 1500€, so 300€ per group)

D: So what makes you think you can teach informatics in this school"
Applicant: "Well, I'm friends with one of your teacher here. We went to university together, where I learn't nothing about informatics and I don't even understand the principles of this subject"
D: "Close enough. Hired, you can teach them all the theory stuffy. You don't have to prepare that yourself another teacher has done so. Just read it from his documents."

*In class with the mentioned teacher talking about Threads*
*Le wild code appears*
while (doStuff())
System.out.println ("Thread working...");
System.out.println ("Thread terminated");
T: "... and most importantly, when you have done all the work be sure to terminate the thread with 'System.out.println ("Thread terminated");'"

Should this teacher be allowed to participate in this seminar about burnouts?
D: "No, I can't afford paying the supplenze."

Staff: "We need to talk with the director about this."
S: "Not in her office. The cafeteria maybe"
*Not in the cafeteria either*
S: "Seems like she didn't come to achool today. Let's try tomorrow"
(^ Stuff that happens almost daily. Screw semicolons. I see her only once a month at most)

*Student send 5000 emails by accident* (Shit happens 😂😅😂😅)
D: "You gonna work here for a full afternoon"
*Student arrives for his punishment*
Staff: "Good that you're here. Do this real quick."
*10 min. Later*
Student: "Done"
Staff: "Well, we have no more work to give you, so you might as well leave"

DONE!!! Good job coming so far.

Our school is supposed to be the best, but internally it's one big meme.

First rant: but I'm so triggered and everyone needs a break from all the EU and PC rants.

It's time to defend JavaScript. That's right, the best frikin language in the universe.

Features:
incredible async code (await/async)
universal support on almost everything connected to the internet
runs on almost all platforms including natively
dynamically interpreted but also internally compiled (like Perl)
gave birth to JSON (you're welcome ppl who remember that the X in AJAX stood for XML)

All these people ranting about JS don't understand that JS isn't frikin magic. It does what it needs to do well.

If you're using it for compute-heavy machine learning, or to maintain a 100k LOC project without Typescript, then why'd you shoot yourself in the foot?

As a proud JS developer I gotta scroll through all these posts gushing over the other languages. Why does nobody rant about using Python for bitcoin mining or Erlang to create a media player?

Cuz if you use the wrong tool for the right job, it's of course gonna blow up in your face.

For example, there was a post claiming JS developers were "scared" of multithreading and only stick in their comfort zone. Like WTF when NodeJS came out everything was multithreaded. It took some brave developers to step out of the comfort zone to embrace the event loop.

For a web app, things like PHP and Node should only be doing light transforms between the database information and HTML anyways. You get one thread to handle the server because you're keeping other threads open to interface with databases and the filesystem. The Nexus.js dev ranting on all us JS devs and doesn't realize that nobody's actual web server is CPU bound because of writing HTML bodies, thats why we only use 1 thread. We use other worker threads to do the heavy lifting (yes there is a C++ bridge look it up)

Anyways TL;DR plz respect JS developers we're people too. ES7 is magic and please don't shit on ES3 or we'll start shitting on the Python 2-3 conversion (need to maintain an outdated binary just cuz people leave out ()'s in their print statements)

Or at least agree that VB.NET is an abomination and insult to the beauty that is TI-84 BASIC

Holy shit. Didn't know I had to vent this out before I had revisited this shit.

Storytime!

Back in May last year, I started working on a dream project (call project X) of mine. Surprisingly it's still a novel idea and shit like this doesn't exist. Made some huge incremental changes. Added all the necessary automation pipeline stuff. Added some sick ass readme with screenshots/badges/glitz/glam.

Worked my ass of for about a month or so until I got distracted by other pending projects in need of clearances. Somewhere partway in that clearance period, I receive a mail from this "GitHub user" asking me why the development of project X had suddenly stopped.

I was a bit taken aback. Firstly because my project had ZERO stars and NO user interaction. Secondly because I hadn't encountered someone with confrontation like this since my middle-school teacher asking me for my homework.

Being the good, responsible child I am, I informed them on my situation and asked them to contribute according to the guidelines and I'd be more than happy to see this becoming a joint effort by the community.

Apparently, they were quite ecstatic to learn that my development was halted. They didn't have plans to contribute. Instead they wanted me to take down the project and stop working on it entirely.

Tough luck fucko.

Their organization had been working on something similar for longer than a couple of years. A similar open-sourced project will *apparently* ruin their market impact and I can *apparently* be sued for it.

I don't know much about open-source "laws" (and I've seen laws fuck people over) but this just seems retarded. At the moment, I'm not quite sure how to continue with the project. I'll still work on it but the fact being that I started receiving threats before stars makes me question the gatekeeping capacity of toxic market conditions (I still don't blame the person entirely. It's just really hard to keep your head above the water)

This is a one off thing but somehow it has definitely hampered my drive to work on the project (combined with the sheer amount of pending project that I've dug my grave with).

On the brighter side I've got 10 anonymous stars with zero promotion. 2 new message threads with productive insights and a person who says "I'm relying on this to work out". So not everything has gone to shit.

When I was in college I used to think deadlock is just a theory concept. First c++ project on my job and I already have one now. 🙃

* Calls themselves "Software Engineer"
* Doesn't know what a thread is.

I swear these coding boot camps are churning out code monkeys whose real skill is building shitty React apps.

I believe a CS degree is necessary if you want to work on something more than CRUD applications.

Nothing against devs without degrees, but at least make an effort because my head will explode next time I have to explain to someone what a thread is and why it's a very bad idea to run blocking code on the main thread.

Knock knock.
Race condition.
Who's there?

I feel that I should mention my reason for having joined devRant.

Although I often write computer programs, I do not consider myself to be a computer programmer, for the problems which I solve often do not pertain to the method which I use to solve a problem with a computer program. Rather, I am an intelligence analyst, and this has been my title for approximately sixteen (16) years.

I joined devRant not only because I wished to better the computer programs which I write, although this could be better accomplished by again reading the specifications for the programming languages which I use, but also because I wished to join an on-line community of which the members are interesting and competent. As I read threads, I observe that both of these requirements have been matched, with the emphasis being placed on the latter requirement.

I thank the majority of you for maintaining an on-line community which is not (total) crap. Ha.

When searching for internship via school I found this small startup with this cute project of building a teaching tool for programming. There were back then 2 programmers: the founder and the co-founder.

Then like 1 week before the internship started, the co-founder had a burnout and had to get off the project, while the company was so low on budget the founder, aka my new b0ss, had to work separate jobs to keep the company alive. (quite metal tbh)

It's funny because I'm a junior developer, 100%. I've been coding as a hobby for around 8 years now but I've never worked in a big company before. (No exception to this workplace either)

First project I get: rewrite the compiler. The Python compiler.
"But wait, why not just embed a real compiler from the first case?"
-nanananana it's never simple, as you probably know from your own projects.

The new compiler, as compared to existing embedded compiler solutions out there, needed these prime features:
- Walk through the code (debugger style), but programmatically.
- Show custom exceptions (ex: "A colon is needed at the end of an if-statement" instead of "Syntax error line 3")
- Have a "Did-you-mean this variable?" error for usage of unassigned variables.
- Be able to be embedded in Unity's WebGL build target

All for the use case of being a friendly compiler.
The last dash in the list is actually the biggest bottleneck which excluded all existing open-source projects (i could find). Compliant with WebAssembly I can't use threads among other things, IL2CPP has lots of restrictions, Unity has some as well...

Oh and it should of course be built using test-driven development.

"Good luck!" - said the founder, first day of work as she then traveled to USA for **3 weeks**, leaving me solo with the to-be-made codebase and humongous list of requirements.

---

I just finished the 6th week of internship, boss has been at "HQ" for 3 weeks now, and I just hit the biggest milestone yet for this project.

Yes I've been succeeding! This project has gone so well, and I'm surprising myself how much code I've been pumping out during these weeks.

I'm up now at almost 40'000 lines of source and 30'000 lines of code. ‼
( Biggest project I've ever worked on previously was at 8'000 lines of code )

The milestone (that I finished today) was for loops! As been trying to showcase in the GIF.

---

It's such a giant project and I can honestly say I've done some good work here. Self-five. Over-performing is a thing.

The things that makes me shiver though is that most that use this application will never know the intricates of it's insides, and the brain work put into it.

The project is probably over-engineered. A lot. Having a home-made compiler gives us a lot of flexibility for our product as we're trying to make more of a "pedagogic IDE". But no matter that I reinvented the wheel for the 105Gth time, it's still the most fun I've had with a project to date.

---

Also btw if anyone wants to see source code, please give me good reasons as I'm actively trying to convince my boss to make the compiler open-source.

Cheers!

I'm astonished again. Linux isn't designed as GUI OS - where Windows has dynamic thread priorities for freshly woken up threads as to increase GUI snappiness.

Now, my CPU has four physical and eight logical cores for SMT. I'm running eight worker threads of some parallel testing stuff, and I'm glad that I chose the AMD 3400G over the 3200G. The CPU load is 100%. On top of that, MP3 audio, the browser, and I'm dd'ing an external USB3 HDD.

Holy shit, the browser is just as smooth as if the CPU were idle. No perceivable lag. I hadn't expected desktop Linux to be that great.

I'm also surprised that the CPU temperature doesn't exceed 44°C despite full load at 21°C ambient, and the cooling is inaudible. Sure, my cooler is massively over-dimensioned to achieve exactly that, but it's still amazing.

It's what I would have wanted ten years ago and only could approach somewhat, but now the tech is actually there.

Oh boy some mutex deadlocks inside the 16 year old, unmaintained, company application framework.

Time to look at the stack traces of 24 different threads and try and guess which one fucks it up

(Send help)

There's a lil tool someone wrote that runs as a post build event for one of our projects. I got bored of watching that tool hog a single CPU thread for like half a minute each time I had to build, so I tried making the thing multi-threaded...

...and it worked! Shit runs on all threads for just a few seconds now 💪🏻

- Team_leader_1: I know you're a frontend developer, but trust me NodeJS has threads :) sync operations don't block the main thread :)
- Team_leader_2: You need to study the theory :) NodeJs can handle further operations during the sync function :) it spawns a new thread, you haven't studied Javascript well enough :)
- Me, very ready to dab on 2 condescending little fucks:

brain: ABSTRACTION ABSTRACTION ABSTRACTION too much ABSTRACTION!

me: jeez calm down a lil i just deployed a boilerplate ember web app with cli tools with next to nothing amount of 'my' code.

b: YES U SUCKER THAT'S WHAT WENT WRONG U DON'T KNOW SHIT ABOUT THE LIL STUFF THAT HAPPENS BEHIND THE SCENES THE FUCK MAN U CALL YOURSELF A CS STUDENT YOU CAN'T EVEN WRITE A COMPILER YET

m: sooo remember when we were studying logic gates and binary conversions and you sigkilled all my threads cuz it was 'boring'?

b: why yes why do you ask

m: WELL that's where we'll end up again if you don't stop nagging me about going down. Trust me, I KNOW how to starve you and you'll beg me to use Python again. You start making advanced data structures in C and the next thing you know you're writing assembly code 'just for fun'.
I have a hackathon coming right up and I have to use a framework or my team loses the advantage. Are we good?

b: well if you put it that way...BUT AFTER THAT YOU'RE TAKING ME TO AN ALGORITHM SESSION

m: *eerily stares at the dusty book in the corner*
you... have a deal

When you test your backend code thoroughly before pushing to production, but a fatal exception with the much larger production userbase causes one of your vital threads to die with a NullPointerException.

Strings and threads are same for the non-computing people.

How I killed five server instances in one shot..

Creating 50000 Threads sounds like a good idea in general, the bad part starts when you use start() in a for loop to run them all at once.

No further comments your honor...

I have not remotely had the energy to post here. Nor reply. And it is a shame because most of you I consider friends. And if not friends, at least excellent aquitances.

People make comments, I dont reply. People make threads, and I dont respond. People make ++s, and I'm a ghost.

I enjoyed shitposting, and asking questions, and hopefully entertaining some of you. I really do.

I'm just in a funk where nothing seems to matter right now and I dont know why, pr how to get out of it.

I have threads, and responses from scor, nanos, nachoscode, and a dozen others I usually enjoy interacting with and it's like all the life has just been sucked right out of me.

I feel isolated and alienated from everything and everyone and I dont know why or when it started. Its just..there. nor how to talk about it.

I think I'm becoming a misanthrope or something. The more I go on with this sensation, the less I want to be around people, and I dont understand why.

I left my previous company because my tech leadership was insensitive and agressive.

However, I am in a start-up right now and CTO is a nut job.

He creates random Slack threads and keeps messaging me like crazy. The co-founders have shut him down multiple times and yet his only success metric is "number of deliveries".

The other day something broke in production and teams were discussing about resolving the bug in one of the Slack channels.

CTO literally wrote this and I wish I was making this up, "let us not look at the logs and trust our code to work fine."

I was baffled and confused. I realised me leaving my previous organisation because of such tech leadership was a stupid decision.

Crows are black everywhere.

After seeing this "old" picture I want to let know at the guyz who are in love with AMD that before Ryzen(s) I was able to cook my fuckin' breakfast's eggs on their fuckin' CPUs.

Big mistakes brings to great solutions and shut up the fuck up AMD, probably your core code is full of vulnerabilities but no one cares about your ultra threads architecture.

As we're all going about our various Easter, Passover, et al., family celebrations, I have the perfect solution to help train your families to stop asking you for help with mundane computer stuff:
Every time someone asks you to do/fix something, give them a full talk about what is going on in their computer around that system.
Don't forget you can talk about lots of things too:
- concurrency
- TCP IP / socket networking
- multi-threaded programs vs. single threads
- RISC vs. CISC processors
- Why linux is better than Windows or Mac
- algorithms
- logarithmic runtime
- teach them how to convert between hex, binary, and base ten
Really pour it on too. Soon they'll either figure out that you are a highly-skilled individual who is not their personal geek squad, or they'll be too afraid of a big lecture to ask for help.
Works with my in-laws like a charm.

Preparing to debug racing condition between 20 different threads.

Not looking forward to this sprint :(

When people use Thread.sleep in unit tests to delay execution of threads

So I'm writing some multithreaded shit in C that is supposed to work cross-platform. MingW has Posix threads for Windows, so that saved already half of the platform dependency. The other half was that these threads need to run external programs.

Well, there's system(), right? Uhm yes, but it sucks. It's incredibly slow on Windows, and it looks like you can have only one system() call ongoing at the same time. Which kinda defeats the multithreaded driver. Ok, but there's CreateProcessA(), and that doesn't suck.

Fine, now for Linux. The fork/exec hack is quite ugly, but it works and is even fast. Just never use fork() without immediate exec(). First try under Cygwin... crap I fork bombed my system! What is this shit? Ah I fucked up the path names so that the external executable couldn't be run.

Lesson learnt: put an exit() right after the exec() in the path for child process. Should never be reached, but if it goes there, the exit() at least prevents a fork bomb.

Well yeah, sort of works under Cygwin, but only with up to 3 threads. Beyond that, it seems like fork() at some point gives two processes the same PID, and then shit hangs.

Even slapping a mutex around the fork and releasing it only in the parent process didn't help. Fork in Cygwin is like a fork in the ass. posix_spawn() should work better because it can be mapped more easily to the Windows model, but still no dice.

OK, testing under real Linux. Yeah, no issues with that one! But instead, I get some obscure "free(): invalid size" abort. What the fuck would that even mean?! Checking my free() calls: all fine.

Time to fire up GDB in the terminal! Put a catch on the abort signal, mh got just hex data. Shit I forgot to compile with -O0 and -g. Next try. Backtrace shows the full call trace, back to the originating line in my program - which is fclose() on a file.

Ahhh I remember! Under Linux, fclosing a file that is already closed makes the program crash. So probably I was closing it twice. Checking back.. yeah that's where it was.

Shit runs fast on several cores now!

When I look at devRant threads, I feel like we're all part of a collective consciousness, growing and thinking and making decisions. Society is a living thing of its own, in the same way that living cells unknowingly make up an individual body. When a question is asked from one node, another node answers, and the result is a repository of questions, answers, opinions, and jokes on an app that might appear as the scrolling thoughts of a singular mind rife with pure, aggressively structured information.

My very first staggering steps with programming were made with Basic, and commands like INPUT that allowed me to create simple text adventures. As silly as it might sound, my biggest hurdle was to figure out how to make realtime action games, reading input from any sort of user device (using GET and JOY) without waiting for input, and designing game cycles in such way that they gave the impression of multitasking (keep in mind there was no such thing as threads). These machines and the Basic interpretor were extremely slow so making anything move a little...er...smoothly, let alone creating a game, was a challenge in itself.

I call this one the tester than knew too much.

Note: The server the tester is running on has a hard drive that is breaking down...

Tester: Remember the error I talked to you about yesterday?

Me: Yeah, what about it?

Tester: Well the server hasn't recovered yet and I haven't restarted anything...

Me: Well the application itself hasn't crashed so our monitoring application doesn't seem to notice that the service is in a bad state. The error seems only to have brought down certain threads within the application.

Tester: No, I think there is a different issue here and has nothing to do with that error, the application is still doing things.
*tails the log*
Tester: See?

Me: As I said some things are still running and are unaffected by the error.

Tester: NO! It has to be caused by the other error I had a week ago where my file got corrupted. As we said I removed the file, restarted it and it worked again, but had the same problem a day later...

Note: The problem is not related, this time the application is running out of file descriptors

Me: Well... If the problem is the same it would have complained about the file descriptors then aswell, not an I/O error.

Tester: Nope, I think you are wrong!

Me: ¯\_(ツ)_/¯

I get asked about being able to hack stuff, like cracking wifi passwords. Mostly I just go along with them and make up some stuff about how you _could_ do it. And explain how it is done, throw in some "yeah its tough"s and words they wont understand. Yeah with a dictionary attack and a powerful CPU with many threads you can definitely do it! You should try it! I say. Convincing them they can. Ofcourse, download kain and abel and look for something like aircrackng on google.

They won't amount to much and probably won't even try it, but I have a laugh. Seeing the hope of hacking and cracking fade away as a child's ice cream melting on a hot summer day.

Hehe

First try at threads in java, search algorithm improved by 35% (56sec to 36sec). Pretty cool to learn 😊

Multithreaded Programming

It's actually safer to use a flat head screwdriver bit to screw and unscrew Phillips head screws than the screwdriver bit that's actually designed for it.. because reasons.

Fuck Phillips heads, they're fucking junk. They're quite a decent match for the shit that consumer electronics often is though... But for anything halfway fucking worth it, why don't we use something like Torx or tri-wing already?! Or rather, anything that isn't Phillips or Pozidriv. Anything that doesn't fuck right off when you slightly overtorque it (without stripping the threads) or want to unscrew it.

I'm so tired.
Got enough sleep but tired nevertheless every day.

Situation in the company isn't helping, would really like to get a review as I'm really close to a 'final' version for productive use, none given.
Didn't think far enough and didn't include various OO-things when starting to program this application, so I had to rewrite lots of it. It certainly got better by the time but as it's a grown structure I'd feel happier if someone other than me had seen and cursed the code.
Coworker that has most experience in C# only once implemented something with multiple threads, couldn't help me there.
Could not test the code yet because the hardware was inaccessible and is now potentially broken.
I really like working independently, nevertheless I feel a little bit lost at sea - I can deal with that, but it's exhausting.
Also, trying to get an answer from the colleague who should act as my supervisor whether or not I can work remotely during a CS related course in the semester break for > 2 weeks now. Course admission is the mid of January so I'd like to have an answer this year so I can repeat the basics I'll need if necessary.
Also, Midterm is coming.

It's a lot of little things piling up right now I wouldn't mind if there were only 1-2 of them.
I'm just so damn tired.
I'll go to sleep now.

Has anyone installed Elasticsearch on Linux - centos to be specific.

Trying to workout why the fucker won't install. Setting up a proof of concept so don't want to use it currently as SaaS.

From why I can tell, it only needs Java, (check) and to be ran as a user other then root (check) but running ./bin/Elasticsearch hangs after a while and starts powering up 100 odd threads with no progress.

I am beginning to hate the relationship between email and my clients. I never thought it would come to the point where email is the worst communication platform I've ever used because some of my clients simply don't know how to use it properly.

I have one client who never uses the subject header in his emails. This makes conversational threads very difficult to follow, and I can't just scan the inbox I have for him. I have to actually do searches on my emails just to find recent conversations.

For some reason nobody knows how to start a new email thread. I have multiple clients that will just take the last email that I sent them, regardless of what it's about, and start a new conversation completely unrelated to the other email by hitting"reply". I end up with email threads that are 60 to 100 emails long and contain many different subjects, which again makes it hard to find anything. Never mind that they've usually put two or three important attachments, or username password combinations, or other valuable information in there amongst all the noise.

Worst of all, I have a few clients and co-workers who insist on starting a new email thread whenever anything about a particular issue comes up. This means that just today I have five separate email threads about the same goddamn issue from the same damn person. Am I supposed to respond to each thread with the same damned information? One of these people is supposed to be both a media consultant and an SEO expert and really should know better. Also, if you do actually send me an email with a subject like "the robot.txt error", please don't give me one sentence about that and five paragraphs about what color you'd like the background to be. That's ridiculous. How the hell am I supposed to find that later? Especially since we already discussed this in the other email that sitting in my inbox.

I swear I am setting up a bug tracking system simply so that my clients can log in and leave me bug reports, and feature requests, and will stop filling up my poor email boxes with what amounts to piles and piles threads that I have to sort through.

For a person who suffers with a form of ADD this is extremely frustrating. Why is it so difficult for my colleagues and clients to write good emails with good subject lines, and reply to the right damn emails?

Am I just being too anal, or does this bother others as well?

Some people would rather post idiotic minion gifs than help find the truth in GitHub threads.

But that's the world we live in.

Ok. Well, I guess I won’t ask for threads...

Let's share information! Communicate! How do we do it? Via email!

You got question? Send an emai!
You want to share some excel? Send an email!
Not sure who to ask? Send the email to everyone!
Have a 100 message long email thread and then need some help? Send the whole fucking thread to me and just add "what do'ya think?"!
Send some attachment in email and then 2 weeks later refer to it saying "but I sent the file to you!"? Well surely I can remember your special email from the hundreds of email I get every week.

I did complain to the mangers that why the hell do we have these mega-email-threads? Why do you send all the meaningles release notes to the whole company? The anwer is simple: all information needes to be transparent and if you don't need the info, then just don't read the email!

Sorry but I'm really, really angry about this.

I'm an undergrad student in the United States at a small state college. My CS department is kinda small but most of the professors are very passionate about not only CS but education and being caring mentors. All except for one.

Dr. John (fake name, of course) did not study in the US. Most professors in my department didn't. But this man is a complete and utter a****le. His first semester teaching was my first semester at the school. I knew more about basic programming than he did. There were more than one occasion where I went "prof, I was taught that x was actually x because x. Is that wrong?" knowing that what I was posing was actually the right answer. Googled to verify first. He said that my old teachings were all wrong and that everything he said was the correct information. I called BS on that, waited until after class to be polite, and showed him that I was actually correct. Denied it.

His accent was also really problematic. I'm not one of those people who feel that a good teacher needs a native accent by any standard (literally only 1 prof in the whole department doesn't), but his English was *awful*. He couldn't lecture for his life and me, a straight A student in high school, was almost bored to sleep on more than one occasion. Several others actually did fall asleep. This... wasn't a good first impression.

It got worse. Much, much worse.

I got away with not having John for another semester before the bees were buzzing again. Operating systems was the second most poorly taught class I've ever been in. Dr John hadn't gotten any better. He'd gotten worse. In my first semester he was still receptive when you asked for help, was polite about explaining things, and was generally a decent guy. This didn't last. In operating systems, his replies to people asking for help became slightly more hostile. He wouldn't answer questions with much useful information and started saying "it's in chapter x of the textbook, go take a look". I mean, sure, I can read the textbook again and many of us did, but the textbook became a default answer to everything. Sometimes it wasn't worth asking. His homework assignments because more and more confusing, irrelavent to the course material, or just downright strange. We weren't allowed to use muxes. Only semaphores? It just didn't make much sense since we didn't need multiple threads in a critical zone at any time. Lastly for that class, the lectures were absolutely useless. I understood the material more if I didn't pay attention at all and taught myself what I needed to know. Usually the class was nothing more than doing other coursework, and I wasn't alone on this. It was the general consensus. I was so happy to be done with prof John.

Until AI was listed as taught by "staff", I rolled the dice, and it came up snake eyes.

AI was the worst course I've ever been in. Our first project was converting old python 2 code to 3 and replicating the solution the professor wanted. I, no matter how much debugging I did, could never get his answer. Thankfully, he had been lazy and just grabbed some code off stack overflow from an old commit, the output and test data from the repo, and said it was an assignment. Me, being the sneaky piece of garbage I am, knew that py2to3 was a thing, and used that for most of the conversion. Then the edits we needed to make came into play for the assignment, but it wasn't all that bad. Just some CSP and backtracking. Until I couldn't replicate the answer at all. I tried over and over and *over*, trying to figure out what I was doing wrong and could find Nothing. Eventually I smartened up, found the source on github, and copy pasted the solution. And... it matched mine? Now I was seriously confused, so I ran the test data on the official solution code from github. Well what do you know? My solution is right.

So now what? Well I went on a scavenger hunt to determine why. Turns out it was a shift in the way streaming happens for some data structures in py2 vs py3, and he never tested the code. He refused to accept my answer, so I made a lovely document proving I was right using the repo. Got a 100. lol.

Lectures were just plain useless. He asked us to solve multivar calculus problems that no one had seen and of course no one did it. He wasted 2 months on MDP. I'd continue but I'm running out of characters.

And now for the kicker. He becomes an a**hole, telling my friends doing research that they are terrible programmers, will never get anywhere doing this, etc. People were *crying* and the guy kept hammering the nail deeper for code that was honestly very good because "his was better". He treats women like delicate objects and its disgusting. YOU MADE MY FRIEND CRY, GAVE HER A BOX OF TISSUES, AND THEN JUST CONTINUED.

Want to know why we have issues with women in CS? People like this a****le. Don't be prof John. Encourage, inspire, and don't suck. I hope he's fired for discrimination.

Historically I've done Java but have recently moved to C# and got the book to do a cert.

Who thought it would be a good idea to start chapter 1 with threads, concurrency, asynchronous calls and PLINQ, then covering boolean expressions, if statements and loops in the section after??

This new guy has a senior position and is 20 years older than me.
Im not a senior because I didn’t study (still have 10y of experience) and i don’t care about the title as Long as the salary is good.
But.. he sucks, he doesn’t know basics, keeps overengineering, I have to explain basic stuff to him over and over again like JOIN in sql, lambda, method references and async threads in java..

He probably makes much more than me and has a higher title..
I feel like nobody notices because I keep helping him to finish his shit.

That sucks!

No matter how many stackOverflow threads you study or how many resources you have, experience is really what makes a very good developer

C/C++ debugging with VSCode sucks ass.

How do I even debug stuff in forks while still debug my threads?
And yeah please just kill my program away, it's not like there happens some necessary housekeeping at exit or SIGINT. FML.

Upgraded from a gen 6 motherboard and cpu to a gen 11. And the difference is asounding.

My old setup did everything I needed it to pretty well. Hell it got me through college as well as multiple part time and full time jobs. As well as the system that I learned about 80% of what I know specifically for my career

But alas the old cpu's age started showing and I'd consistently throttle multiple threads when compiling or even just using 7z on large folders. Hell deleting anything above a couple hundred mb would pause for a few seconds

The new cpu is immensely faster on such tasks (probably cause of the extra 2 cores and cpu improvements since gen 6)

I haven't been this excited since I got my first SSD a few years ago and saw the immense boot time improvements. Maybe soon I'll get an nvme drive and really be zooming with this setup 🤣🤣🤣

I decided to do a daily Blender render just as a creative challenge for myself. I was so excited because I built an awesome computer this year and was eager to put it to use, only to be hit with seemingly random BSODs and crashes a couple seconds into the render.

As it turns out, my CPU cooler is woefully inadequate to handle 32 threads running at once, which was the cause of my crashes. Turning the render threads down to 8 keeps the temps low enough to finish the render.

In a way, it's a relief because the alternative was a problem with my $900 GPU. I've ordered a bigger CPU cooler and well reviewed heatsink paste which will hopefully fix it. If not, I'm going to have to go water-cooled, which I really don't want to do.

I'm writing a multi threaded program right now and just pray for the threads not accessing my var at the same time :) but I cannot use a locking algo because my 1st thread needs to access that var up to 1000 times a second. Pray for it to work as it should 🤔😇

Not really a rant and not very random. More like a very short story.

So I didn't write any rant regarding the whole Microsoft GitHub topic. I don't like to judge stuff quickly. I participated in few threads though.

Another thing is I also don't use GitHub very much apart from giving 🌟 to repos as a bookmark. Have one hobby project there. That's all. So I don't worry that much. I'm that selfish and self concerned. :3

I was first introduced to version control system by learning how to use tortoisesvn around 2008. We had a group project and one of the guys was an experienced and amazing programmer unlike the rest of us. He was doing commercial projects while we were at our 1st and 2nd year. Uni had svn repo server. He taught us about tortoisesvn. He also had Basecamp and taught us how to use it as well. So that's how I learned the benefits of using versioning tools and project management tools. On side note, our uni didn't teach any of those in detail :3

After that project, I was hooked to use versioning tools. So until school kicked me out, I was able to use their svn server. When I was on my own, I had to ask Google for help. I found a new world. There are still free svn services that I can use with certain limited functions. That's not the new world; I found people saying how git is better than svn in various ways. It was around 2010,2011.

At first I was a bit reluctant to touch git because of all the commands in terminal approach. But then I found that there is tortoisegit. I still thank tortoisesvn creator for that. I'm a sucker for GUI tools. So then I also have to pick which git servers to use. Hell yeah, self hosted gitlab is the way to go man. Well that's what the internet said. So I listened. I got it up and running after numerous trial and error. I used it briefly. Then I came back to my country on 2012-2013; the land of kilobytes per minute (yes not second, minute).

My country's internet was improved only after 2016. So from 2013 to 2016, I did my best not to rely on internet. I wasn't able to afford a server at my less than 10 people, 12ft*50ft office. So I had to find alternative to gitlab which preferably run on windows. Found bonobo and it was alright. It worked. Well had crazy moments here and there when the PC running Bonobo got virus and stuff. But we managed. We survived. Then finally multi national Telecom corporates came to our country.

We got cheaper and faster mobile data, broadband and fiber plans. Finally I can visit pornhub ... sorry github. Github is good. I like it. But that doesn't mean I should share my ugly mutated projects to the rest of the world. I could keep using Bonobo but it has risks. So I had to think for an alternative. I remembered that gitlab didn't have cloud hosting service when I checked them out in the past. So I just looked into Bitbucket and happy with their free plans of 5 users and unlimited private repos. I am very very cheap and broke.

That's why I said I don't really care that much about the whole M$GitHub topic at the beginning. However due to that topic, I have visited GitLab website again and found out they have cloud hosting now and their free plan is unlimited users and unlimited repos. So hell yeah. Sorry BB. I am gonna move to cheaper and wider land.

TL;DR : I am gonna move to GitLab because of their free plan.

Ugh. I hate gmail threads. Especially when people just hit reply and quote the whole thread in their next email.

Going back and sifting through these threads to find relevant information is always a pain in the ass.

I like the new gmail UI. It's clean and works perfectly especially when you have keyboard shortcuts on.

But these threaded messages. Gah!

Long long time ago when recharge coupons we a thing, I used to try out more codes in the series and waste my time. After failing a lot over this, I started trying out different USSD codes to see what other stuff is out there. This got me to stumble upon facebook and twitter on USSD. I'm not sure now but, twitter was probably *515# from my carrier.

Facebook. I remember chatting for quite a long period using this. Very slow and limited yet, fun. The USSD message expires within ~60secs. so you have to type the chat message before that or you lose everything you typed. The phone was no smartphone that would allow me to copy the text from the USSD input. On top of that panic, was a character limit to these messages. I remember hitting send while being midway through a message just so I don't lose what I typed, on a T-9 keyboard. Still miss those!

The person on the other side would receive a half message due to this, and would start replying without any patience, to which I panicked as now there's a new thing to respond to, and a half message which I'm waiting to complete.

Later over the weekend when I was allowed to visit the cyber cafe for an hour or two with 15-30 INR, reading the chat threads, being able to use the five sticker packs:) and thus continuing on a computer was fun. But, as the time at the cafe expires, I had to immediately shut off my session or I'd be charged more. Thus, I was left in the middle of a conversation again, and had to continue over USSD.

Using social media without any internet like this was quite fun in a weird way. If I get a new message, I'd get a USSD alert, and then an sms if I didn't reply in some 10-15mins!

This had all the features like like and comment. Friend requests too. For the posts in a "timeline" which was new and fancy in those days, all you see is the caption of a post which also gets truncated quite a bit as USSD also has to show it's options like:
1. Like
2. Comment
3. Next Post
4. Main Menu

This was around '13 or '14 I guess. After which I later got my first computer- a laptop. Anyways, the tactile feel of pressing the buttons on a T-9 keypad is nostalgic to me. 😅 And if you were a pro at texting, u must hv used shrtcts lyk dis too w/ emojis lyk :-) <3

Can't get over how many big companies get away with poor/no documentation for their own APIs. The past week i have been working with a large insurance company that only via email threads explained what endpoint to send files to and what username I could use to get this to work.

I also worked with a major courier service last month that only had a two page document for all their methods and one of the pages was explaining the transportation of data via imagery haha.

!rant

We have to programm a branchAndBound algorithm for school. Since it was running kinda slow, we decided to use multiple threads. Nailed it first try.

I am reviewing a piece of code as I type this, and I just had to make a rant about it. In the code there's all these measures for syncing multiple threads, while the entire thing runs does not even use threading. But that's not the worst: when an InterruptedException is caught, is calls Platform.exit() WHICH CLOSES THE FUCKING PROGRAM. WHY WOULD YOU EVER DO THAT?

can there just ONCE be a FUCKING react native library that works as it is FUCKING documented?

but NOOOO, gotta always sift through the absolute shit pile that is GitHub issues threads digging out arcane horseshit to make the stupid shit work just like the little managers want

on and on into the circus enternity

I love a number of the little slack "all clean" icons when you catch up on threads. They're adorable. My personal favorite is the floptopus.

Anyone else have fave examples of adorable, ideally platform mascot-related pieces of task-accomplishment-reward-bait (octocat, go gopher, etc etc?

It's a rant bc fuck anyone who's too cool for cute shit :p

Working with threads is like a box of chocolate
you'll never know what you gonna get

Some people, when confronted with a problem, think, 'I know, I'll use threads' - and then two they hav erpoblesms.

Last year, we had computers architecture class where we study about the architecture of processors like RISC, CISC, SIMD... The teacher was a nice person but didn't have much knowledge on the field. I read some of Patterson&Hennessey book (computer organisation and design iirc) and learned how to use openmp and mpi, and then in the last lab we were required to optimize matrix multiplication using 4 threads in openmp, the best students optimiseed for 4 times at best, meanwhile I made 16 times optimisation and showed the teacher how fast it was. She was really impressed lol

@dfox New excellent algo sort makes lots of old threads bumb which means better notifications is suddenly more important.

I'm wishing for notifications grouped per thread and with a line or two of the rant/comment the notifications is about.

Daaamn! I needed to process some data simultaneously using PHP, so I thought of using Threads to make things faster, checked out SO and discovered that the available Thread class can only be used in cli environment not on a web server ... FML 😑.
It's like these moments that I remember why I hate PHP, and regret accepting this job.

I miss Java 😣😣

What would be the better approach for loading very big in size or in quantity files in java?
1) Loading data parallel through multiple threads
2) Loading data in series in a single thread
3) any other methodology?

Just asking because loading time is varying both cases.

It's always so funny when a person starts using multiprocessing in Python, because if there's "multi", obviously THIS is the thing that should free the person from a headache of having GUI frozen. You know, because it does "multiple" ehm... stuff..... at once....... yeah. And it's popular, it must work for me too! Oh how often I see this. :D

Stupidly enough that's not entirely a user's fault, but Python's as naming things with "multi" doesn't end up well basically with anything. I bet if there was such thing as multipointer in C half of the beginners would be totally fucked and the other one would just break their machines beyond repair with a joy.

Yet... reading the damn documentation should be a requirement before using threading or multiprocessing to prevent the confusion, because there's this funny difference between multiple threads and multiple processes which will haunt you unless you see what's what and use it correctly.

A C++ program that spawns as many threads as it can to open TLS 1.2 connections to a given server and send random data.

Needed this to test scalability of one of our services.

Slack threads are plain shit.

Worst practice -- our application isn't built to properly handle threads and I just added a Sleep statement to wait for the backend process to replicate its data. I feel so guilty and dirty.

When McDonald's janitors are writing code...

Dev1: *creates a MR*
Code: for each HTTP request do

// stuff
Executors.newFixedThreadPool(validators.size()); // effectively meaning will start 7 new threads for each incoming request
// other stuff

Dev2: ^^ ??? Fix that shit. This will cause performance problems.

Dev1: *updates the code*
Code:

// stuff
int THREAD_NUMBER = 10;
Executors.newFixedThreadPool(THREAD_NUMBER);
// other stuff

Everyone: 🤦‍♂️🤦‍♂️🤦‍♂️🤦‍♂️

Can I BE facepalming any more?

Computers have threads. Computers are sewing machines

This is the reason why I never prefer Google Chrome!! It freaking kick starts number of threads in the background that keeps hogging your system resources!! The one memory hungry browser!!

Once again, I urge you all to read any LLM threads on hackernews... its funny seeing tech bros debate things they clearly don't understand

it also wouldnt hurt for them to read perhaps just one philosophy book, since they are attempting to argue about what conciousness actually is (still an open question anyway) so ultimately, what i am trying to say is, these stupid threads end up being a bunch of hot air being blown around that doesnt really accomplish anything

i will say it is funny though how close some of these tech bros think we are to AGI with these LLMs 😂

imagine thinking a text generator is nearly general intelligence = clueless

promises in JavaScript have really spoiled me

it's the most optimal way to do async without leaving much on the table

there's a promises library in rust and the guy who wrote it says it sucks because it spawns new thread every time you execute a bunch of promises

and I finally, through my fogged brain, managed to get the bright idea to write what I want to make in rust in JavaScript and holy hell it's sexy to work with promises. there's no performance left on the table. you do things as fast as possible

but if I take this JavaScript usability code I made and make it possible syntax-wise in rust I don't see how I would be able to do it without starting new operating system threads every time I execute any promises (or set)

I can take the overhead hit but this sounds retarded

and this isn't even touching upon how in rust everything needs to have a predetermined data type. so you can do lambdas and capture variables and send in variables into a thread that way, but to return the return object must be a consistent type (synchronizing the order data was sent in to the data sent out aside, haven't written that yet should be fine though)

which is fine if you are making a threadpool and it'll all be returning one data type
but this means you can't reuse a threadpool you made elsewhere in the program

the only thing that could fix async is to literally be compiler-enabled. it would have to work like generics and automatically make an enum of every type that can return, and only then could you re-use the threadpool

Am i the only one who really wants a chat and follow option on DevRant?
I find it very uncomfortable to maintain long comment threads of 20+ comments especially when you're discussing with a single other ranter on a certain issue :/

the first most annoying thing in devrant are new users

the second most annoying thing is "new comments on a rant you commented on" notifications. They require maintenance work, and I can't even mute threads on desktop

Was writing a multithreaded program in Java with an infinite while loop (for waiting). The thread was never preempted. Added a print statement inside the while loop and everything started working :/

Now I need to print a stupid message just so the program works :P

Anyone here using Blind?

A kind of a professional social but seems a little better than LinkedIn.

It's purely based on Q&A model like Quora.

A friend keeps sharing some threads and some are worth spending a couple of minutes for quick read.

So I got my compute shader rasterizer working pretty well now which is great. I now also have a fallback to hardware rasterization for triangles which are a bit sussy (mostly just too large) and getting that implemented without tanking performance (gazillion threads hitting the same atomic variable at the same time) involved some tricky workgroup/subgroup hackery but I'm happy with it

Only problem... I have like 90%+ SM occupancy (which is great) but I also have 90%+ SM occupancy which means the nvidia drivers think I'm mining cryptocurrency and start bottlenecking my compute performance at random. It slowly goes up to 3x, then it slowly goes down again, then it slowly goes up again... argh

Thanks, miners 😐

People responsible for closing threads on stackoverflow for "We don’t allow questions seeking recommendations for software libraries" should die and rot in hell forever.

My threads when I started learning concurrency...

One responsibility of our team is general code QA for the entire dev department, DevMgr walks in our area yesterday…
DevMgr: “Has anyone reviewed the new WPF threaded model execution code?”
- everyone on the team responds “no”
DevMgr: “Can we get a review on that code ASAP? If it works as well as the developer said, it’s going to solve the lock up problems users are experiencing and automatic logging of errors.”
DevA: “Well, no amount of code is going to stop users from performing bad searches locking up the user-interface. That code is just a band-aid around the real problem. If the developers would write unit tests first …”
- rant about 5 minutes on unit testing that had nothing to do with why the DevMgr was here
DevB: “Yea, the code probably isn’t written to handle threads correctly. All the threading they’ve done so far is –bleep-”
DevMgr: “Oh, I wasn’t aware of that. Get me the results of the code review and if they don’t have unit tests, delete it from source control and let the developer know it’s not up to our standards.”
OMFG!! You have not even seen the code!
OK, DevA ..what the –bleep- does unit testing have anything to do with the user interface! You know the DevMgr is too dim to understand the separation of concerns. Shut your pompous ‘know-it-all’ mouth.
DevB…what the –bleep- have ever done in WPF? You manage the source control and haven’t written any C# in two years and never, ever written code for any significant project. Take that “handle threads correctly” and shove it up your –bleep-. Pompous –bleep-hole. Go back and watch youtube and read your twitter while the grown-ups get the work done.

Any way to block/ignore certain bullshitters? Just blocking the threads is enough.

Note for smartasses: freedom of speech is not equal to having to listen.

I learned very quickly that magic globals are baaaaad.

I mean, it's easier than using a queue for passing data between threads, right?

Why do SAMBA network drives have to suck this much? Yeah I understand that compiling to a network drive is probably a bad idea just for performance reasons alone but can't you at least not fuck with my git repo?

Now that I have to use Microsoft Teams chat, I don't find Slack that bad anymore. Teams doesn't support threads, source code is poorly formatted without any syntax highlighting, and emojis look shitty.

So i'm visiting the JavaScript bubble every now and then when i'm writing on the userscript i develop to fix bugs in our ticketing system or fix some clients website they negelected. Every time i'm searching for answers to the weird problems that inevitably turn up i have to filter out all the threads that derail with the classic 'google jQuery basic arithmetic plugin' craziness to find an actual vanilla solution to my problem.

All the time i wonder why on earth people put up with this framework hell. This is part serious question and part rant but seriously, how did we come to this? With all that jQuery, React, Node, whatever stuff i'm kinda losing the overview over what's even todays standard. I always try to keep my code as vanilla as possible without using external libraries. But it seems the entire web development industry is heading the completly other way. I tried to look into a few frameworks but i never really see the appeal. Just now i looked up react native because the last 20 rants talked about it and immediately noped out because they fucking create a DOM in js, why the fuck would you do this?!

Worst thing about this framework shithole is that some frameworks are beeing pulled into the mix for very weird and unnecessary reasons. Best example is a charts library i recently used to visualize a database of temperatures that was completely written in native js but pulled jQuery in for the equivalent of window.addEventListener('load',function(stuff)) and i was furious. I rewrote the code and could throw out the jQuery dependency with no problem. What the fuck is wrong with people?

Alright since you made it here: I'm not trying to throw any of you under the bus for using frameworks. I just fail to understand why you would use these. To each their own and unless your site has the performance of the ticketing system i use at work that takes like 15 seconds to load one fucking page i won't complain at all. But pull in a framework just to do a task you can easily do in native js in remotely the same timeframe you are on my list.

!rant

TIL I can help support devRant for less than the cost of a coffee per month. (And you can too, if you're not already) I'm digging the edit time extension and the ++ tag in threads.

Cheers, dfox and trogus!

I wanna make a c+friends language and it'd be dev friendly and will throw lots of errors on compile to show love. Also it'll compile slower with each newline so you can always say "it's compiling" there will be classes but people instead and then instead of new I'll have create. As for loops let's go with a friendly do while loop and dontdo while as normal while or dowith i while to have a friendly for loop. Instead of ifs let's say decide() and instead of else let's have or. Instead of functions I'll have well you need no functions you'll have jumps and tests before jumps just like assembly has. Oh and everything will be a pointer because then it runs nicer. To create a variable you can't use = because that's the equal sign in decide you need to use "var int myint is 69" because why not. Then to print to the console "console.outputstream.out(myint)" instead of threads I'll have please like "please work" where work is a jump target. I hope you'll enjoy this language ^^

People really have short term memories. It seems everyone has suddenly forgotten the nonexistent lack of privacy at Zuck’s platforms.

To be fair, I think competition is good for consumers and Musk has been doing a very terrible job of managing Twitter.

But not having most platforms of social communication controlled by one company would be better.

In last episode of "How SystemD screwed me over", we talked about Systemd's PrivateTMP and how it stopped me from generating SSL certificates.

In today's episode - SystemD vs CGroups!

Mister Pottering and his team apparently felt that CGroups are underused (As they can be quite difficult to set up), and so decided to integrate them into SystemD by default. As well as to provide a friendlier interface to control their values.

One can read about these interactions in the manual page "systemd.resource-control"

All is cool so far. So what happened to me today?

Imagine you did a major system release upgrade of a production server, previously tested on a standalone server. This upgrade doesn't only upgrade the distribution however, it also includes the switch from SysVInit to SystemD. Still, everything went smooth before, nothing to worry now then, right? Wrong.

The test server was never properly stress-tested. This would prove to be an issue.

When the upgrade finishes, it is 4 AM. I am happy to go to bed at last. At 6 AM, however, I am woken up again as the server's webservices are unavailable, and the machine is under 100% CPU load. Weird, I check htop and see that Apache now eats up all 32 virtual cores. So I restart it, casting it off to some weird bug or something as the load returns to normal.

2 hours later, however, the same situation occurs. This time, I scour all the logs I can, and find something weird - Many mentions that Apache couldn't create a worker thread? That's weird.

Several hours of research and tinkering later, I found out the following:
1 - By default, all processes of a system that runs SystemD are part of several CGroups. One of these CGroups is the PID CGroup, meant to stop a runaway process from exhausting all PIDs/TIDs of a system.

This limit is, by default, set to a certain amount of the total available PIDs. If a process exhausts this limit, it can no longer perform operations like fork().

So now, I know the how and why, but how should I solve this? The sanest option would be to get a rough estimate of just how many threads the Apache webserver might need. This option, though, is harder, than apparent. I cannot just take the MaxRequestsWorkers number... The instance has roughly double the amount of threads already. The cause being, as I found out, the HTTP/2 module, which spawns additional threads that do not count towards this limit. So I have no idea what limit to set.

Or I could... Disable the limit for just the webserver via the TasksAccounting switch. I thought this would work. And it did seem to... Until I ran out of TIDs again - Although systemctl status apache2.service no longer reported the number of tasks or a task limit of the process, the PID CGroup stayed set to the previous limit. Later I found out that I can only really disable the Task Accounting for all the units of a given slice and its parents.

This, though, systemctl somewhat didn't make apparent (And I skimmed the manual, that part was my fault)

So... The only remaining option I had was to... Just set the limit to infinite. And that worked, at last.

It took me several hours to debug this issue. And I once again feel like uninstalling systemd again, in favor of sysvinit.

What did I learn? RTFM, carefully, everything is important, it is not enough to read *half* the paragraph of a given configuration option...

Oh, and apache + http/2 = huge TID sink.

Nothing like using a ThreadPoolExecutor to thread out my shitty selenium task, so it will go just a bit faster.

So Instagram recently launched 'Threads' as it's standalone messaging app... Although it seems like a bad replica of Snapchat I still liked the minimal messaging interface. Have switched my personal account from main app to threads to improve productivity. Let's see how it turns out to be in the next few days.

throw new exception("There were not enough free threads in the ThreadPool to complete the operation.");

Brain == toast

We use Slack at work for IMs.

There are tons of threads created in each DM, group chat, and channels.

There is a purpose to each thread.

But.. BUT.... Engineering team responds to a thread and also sends the same message in channel.

What's the fucking point of the thread...

FUCKING STOP SPAMMING WITH DUPLICATE MESSAGES.

I have a cup of green tea in my hand right now and I feel like pouring it on myself.

Third tier geniuses from Timbuktu.

As a part of a project in university, we are making an extension to a functional programming language, made in Scala. One of my groupmates had made some fancy logic with spawning threads, but we had some issues with multiple function parameters. Me and another mate have then spent like 3 days trying to figure out the problem, only to realise he forgot a $ sign in string interpolation for naming parameter. Talk about feeling like you're wasting time 🙃

Can we normalize NOT using giant acronyms in GitHub issue threads? Nobody understands what you are saying.

The same goes for you, HackerNews users, we can't psychically jump into your ASCII LOL DDD ABC XYZ brain and automatically know what you mean.

So I recently finished a rewrite of a website that processes donations for nonprofits. Once it was complete, I would migrate all the data from the old system to the new system. This involved iterating through every transaction in the database and making a cURL request to the new system's API. A rough calculation yielded 16 hours of migration time.

The first hour or two of the migration (where it was creating users) was fine, no issues. But once it got to the transaction part, the API server would start using more and more RAM. Eventually (30 minutes), it would start doing OOMs and the such. For a while, I just assumed the issue was a lack of RAM so I upgraded the server to 16 GB of RAM.

Running the script again, it would approach the 7 GiB mark and be maxing out all 8 CPUs. At this point, I assumed there was a memory leak somewhere and the garbage collector was doing it's best to free up anything it could find. I scanned my code time and time again, but there was no place I was storing any strong references to anything!

At this point, I just sort of gave up. Every 30 minutes, I would restart the server to fix the RAM and CPU issue. And all was fine. But then there was this one time where I tried to kill it, but I go the error: "fork failed: resource temporarily unavailable". Up until this point, I believed this was simply a lack of memory...but none of my SWAP was in use! And I had 4 GiB of cached stuff!

Now this made me really confused. So I did one search on the Internet and apparently this can be caused by many things: a lack of file descriptors or even too many threads. So I did some digging, and apparently my app was using over 31 thousands threads!!!!! WTF!

I did some more digging, and as it turns out, I never called close() on my network objects. Thus leaving ~30 new "worker" threads per iteration of the migration script. Thanks Java, if only finalize() was utilized properly.

Don't you just wish hacker news ycombinator move there threads to here ?

Let's all flock to facebook's (I'm sorry, META's) latest application, forgetting all the trouble they've had about privacy breaches and the selling of customer data and other shady shit.

Sounds like a wonderful idea.

And give that company even more of a monopoly over the internet. Communication? Whatsapp and facebook messgenger. Social Networks? Facebook and Instagram.

I understand not giving a shit if you do not have a background in tech but come on. Learn to live without twitter you internet addicted dumb fucks

Just 5 days? What. Some technical problems take years to solve and you auto-close threads after just 5 days? Why you do this MongoDB 🗑️

So you write multi-threaded programs in Perl; Does this position also include a gun to shoot myself with?

Without a doubt it has to be the internal company search engine/file finding tool @thewamz and I wrote.

The company has a wide UNC network with files scattered all over the place and they need a way to keep track of where the files get moved to (they can and do get moved). The original tool was written in Java/Tomcat and didn't use any frameworks or utilities beyond custom written ones, no orms, and the SQL was just raw strings. The program didn't take into account that files might be moved or deleted so it never removed anything from the database, it just kept adding files and never removing them.

It however never stores files itself, just links to files elsewhere on the UNC network.

It took six months to get it into what might be a stable beta or release candidate state. The user interface is good, very simple and intuitive, the whole thing was rewritten in python/django, there were issues with utf 8 (and mysql not fully supporting utf 8 in its own utf 8 mode), we added a regex search mode (which was sorely lacking), the search used to take up to fifteen minutes however we sped it up to less than a minute (worst case when a user simply puts "^$" as the regex search). It has a multi threaded design which does some checks to ensure it doesn't spawn too many threads and get stuck in constant Gil switching. Still some bugs to fix, like moving the processing of results returned by the server in a web worker so that the content widget doesn't lock up processing millions of search results and moving the back end to use asynchronous python might gain a performance boost. But on the whole I think the system is ready to replace the older system that all the users are frustrated with and constantly complain about.

However the annoying bit is... How to actually get the new system online, while I am responsible for the development of tools and their maintenance, I am not responsible for their initial deployment and that means I have no idea when (or even if) my new tool will even ever be released :/

first time working with android. using threads debugging is not working like it should. app works great when I'm not debugging. code doesn't get executed WTF i really need that stressball FML

Been working for almost a year, really hard, on a serious attempt to make GUI development on Python fun, easy, flexible, with a full array of widgets and do it in a way that complete beginners can understand and the professionals will enjoy because it's so easy. My solution is called PySimpleGUI.
My 'rant' is the downvoting and slandering happening on places like Reddit is done by people that haven't tried to use it and most haven't installed it. Yet, they're experts in how sh*tty it is.... even though nothing stated as being a problem is truthful. When asked for more direct feedback on what's wrong, how it can be improved, the active rant threads go silent.
I've never been on devRant, so I hope I'm doing the right thing here! I'm just blowing off steam, not trying to start some holy war.

People that dont use slack threads.
Fuck em.

"Yeah, lets use slack, it is much more organized and will improve structured conversation"

And then they never fuckn use the god damn CORE feature but dump their replies into the channel like monkeys throwing their shit around everywhere except in the place the shits supposed to go.

personal projects, of course, but let's count the only one that could actually be considered finished and released.

which was a local social network site. i was making and running it for about three years as a replacement for a site that its original admin took down without warning because he got fed up with the community. i loved the community and missed it, so that was my motivation to learn web stack (html, css, php, mysql, js).

first version was done and up in a week, single flat php file, no oop, just ifs. was about 5k lines long and was missing 90% of features, but i got it out and by word of mouth/mail is started gathering the community back.

right as i put it up, i learned about include directive, so i started re-coding it from scratch, and "this time properly", separated into one file per page.

that took about a month, got to about 10k lines of code, with about 30% of planned functionality.

i put it up, and then i learned that php can do objects, so i started another rewrite from scratch. two or three months later, about 15k lines of code, and 60% of the intended functionality.

i put it up, and learned about ajax (which was a pretty new thing since this was 2006), so i started another rewrite, this time not completely from scratch i think.

three months later, final length about 30k lines of code, and 120% of originally intended functionality (since i got some new features ideas along the way).

put it up, was very happy with it, and since i gathered quite a lot of user-generated data already through all of that time, i started seeing patterns, and started to think about some crazy stuff like auto-tagging posts based on their content (tags like positive, negative, angry, sad, family issues, health issues, etc), rewarding users based on auto-detection whether their comments stirred more (and good) discussion, or stifled it, tracking user's mental health and life situation (scale of great to horrible, something like that) based on the analysis of the texts of their posts...

... never got around to that though, missed two months hosting payments and in that time the admin of the original site put it back up, so i just told people to move back there.

awesome experience, though. worth every second.

to this day probably the project i'm most proud of (which is sad, i suppose) - the final version had its own builtin forum section with proper topics, reply threads, wysiwyg post editor, personal diaries where people could set per-post visibility (everyone, only logged in users, only my friends), mental health questionnaires that tracked user's results in time and showed them in a cool flash charts, questionnaire editor where users could make their own tests/quizzes, article section, like/dislike voting on everything, page-global ajax chat of all users that would stay open in bottom right corner, hangouts-style, private messages, even a "pointer" system where sending special commands to the chat aimed at a specific user would cause page elements to highlight on their client, meaning if someone asked "how do i do this thing on the page?", i could send that command and the button to the subpage would get highlighted, after they clicked it and the subpage loaded, the next step in the process would get highlighted, with a custom explanation text, etc...

dammit, now i got seriously nostalgic. it was an awesome piece of work, if i may say so. and i wasn't the only one thinking that, since showing the page off landed me my first two or three programming jobs, right out of highschool. 10 minutes of smalltalk, then they asked about my knowledge, i whipped up that site and gave a short walkthrough talking a bit about how the most interesting pieces were implemented, done, hired XD

those were good times, when I still felt like the programmer whiz kid =D

as i said, worth every second, every drop of sweat, every torn hair, several times over, even though "actual net financial profit" was around minus two hundred euro paid for those two or three years of hosting.

!rant
is pre-debugging a good thing?
I have a habit of implementing a project(for e.g. a mobile app) like this: See the project, break the tasks to be done into small parts(Like UI layouts- setting, listeners to implement , graphics involved, background threads required, databases necessary, etc.)and then code each of them step by step , while simultaneously testing their working (For all possible test cases I could think of ) side - by side. this results in my project getting developed in far more time than other people, but I always have something good and working all times to show to my bosses.But I really feel stupid when I spend 2 hours handling the animations and ui while I have yet to look into databases and other more important stuff

I guess that's a habit from my good old python days(its IDLE was a playstation for me) but I wish to know better approaches,if any?
