Today I discovered that we have a CSV export button for an order transaction system, on a page which is completely disconnected from the rest of the website.
It is only being called by an internal server, used by our Data department.
They run selenium to click the button.
Then they import the CSV into a database.
That database is accessed by an admin panel.
That admin panel has an excel export button.
Which is clicked by our CFO. But he got bored of clicking, so he uses IFTTT to schedule a download of the XLS and import it in Google Sheets.
That sheet uses a Salesforce data connector.
Marketing then sends email campaigns based on that Salesforce data...

Oh I have a good one.
A dev once was added to the team -he deleted all of the whitespace from the backend code (minified) and called that optimising. We had a lot of back and forth and me reverting the things back to non minified and him back to minified on live environement. I shit you not i had to endure that shit and he kept on insisting that I'm the shitty developer because I don't know how to optimise. I'm starting to rage even thinking about it....13 -
Ahh the gems you find in codebases where only one person each is in charge of the frontend and the backend.16

On March 10th russian government tried to block or at least slow down twitter because twitter refused to delete some posts that russian govt wanted to be deleted.
Things that were down that day in russia:
- rostelecom (largest russian isp)
- FSB (russian CIA)
- SKRF (russian FBI)
- RKN (russian FBI but for internet control)
- gosuslugi (basically the govt website for all utilities imaginable including but not limited to medical help, taxes, passports, everything)
- kremlin website
Things that were up that day in russia, operating at a regular speed:

My first year at the Uni I believed I was "superior" to others as I knew Python and they knew C.
I'd give my kidney to someone who can go back in time and bang some sense into my empty skull.9 -
Me: Optimize a sort & match method in backend because users complain it's a bit slow.
Coworker: These algorithms are both O(n), so they're identical *closes PR*
Me: *start zoom call* "Heeeeeeeeeey Iiiiiiiiiii wouuuuuuuld liiiiiiiiike toooooo diiiiiisscuuuuus thaaaaaaaat puuuuuuulllll reeeeeequuuueeest yooooouuuuu cloooooossseeeed"
Coworker: "wtf are you doing, why are you talking so slow"
Me: "No matter whether I talk fast or slow, the information still reaches you in O(n) time, so why are you complaining"
I fucking hate it when people misunderstand the purpose of (or abuse) big O notation. It's an estimate of how an algorithm SCALES once the set increases in size, in which case you leave out both less significant terms and constant factors.
But those terms and factors are important when you're talking about the DIRECT PERFORMANCE of the algorithm on fixed-size sets, instead of SCALING to larger sets.
1n and 10n are both O(n), but 10x performance on a job that used to take 10 minutes is still significant.19 -
HR made a day long inclusiveness meeting. About why there are so few women in the department. Basically the conclusion the HR rep was looking for was “toxic masculinity” and it was super uncomfortable.
The engineering teams couldn’t actually participate much because most of them worked on teams without any women and have absolutely nothing to do with hiring. The male engineers were trying to play along and give the right answers. We had to do flip charts and beak into teams and etc.
The HR kept singling out the same three women in engineering and telling the men to “shut up and listen to them”. The female engineers were like, “i don’t know. I don’t have much to say about it.” The HR rep continued to drill those three women to the point that it was uncomfortable.
The engineering hiring manager lost it before noon. He went to his desk and grabbed a stack of resumes. “You gave me a stack of 60 resumes. Looking at names only four applicants are female. Those applicants don’t have education or experience for engineering. If you want more female engineers in the office you have to put qualified applicants into the stack. Forcing these three engineers to talk in front of our department over and over and saying the men have to shut up is not making the workplace less toxic.” Then he told the three engineers, “This meeting is now optional for you three and you are welcome to do anything you want with your time.”
After lunch, all the female engineers went back to their desk and worked. The HR continued to shame the men in an angrier tone for the rest of the day telling everyone “how men can be” from personal experience because they were the ones now representing all women.
Eight bloody hours of that.131 -
Christmas lights were blinking randomly IN SECTIONS without any sort of "control brick", just with a plain wall plug and TWO wires coming out of it.
In this house we obey the laws of physics, I immediately called magic on this and started digging. I found out that was like five chains of lights wired in parallel, and every chain contained one special lamp that had a thin plate of some thermal-sensitive material inside. It heats up which makes it go straight, thus breaking its chain until it cools down enough to curl again and make the contacts touch.
Brilliant and really cheap way of making randomly blinking Christmas lights without any kind of controller, with just two wires and some physics. That's what I call "nocode".11 -
It's a fucking shame computed goto didn't make it into the C standard.
It's by far my favorite non-standard feature of C. Writing this VM would suck without it.17 -
Chrome, Firefox, and yes even you Opera, Falkon, Midori and Luakit. We need to talk, and all readers should grab a seat and prepare for some reality checks when their favorite web browsers are in this list.
I've tried literally all of them, in search for a lightweight (read: not ridiculously bloated) web browser. None of them fit the bill.
Yes Midori, you get a couple of bonus points for being the most lightweight. Luakit however.. as much as I like vim in my terminal, I do not want it in a graphical application. Not to mention that just like all the others you just use webkit2gtk, and therefore are just as bloated as all the others. Lightweight my ass! But programmable with Lua, woo! Not like Selenium, Chrome headless, ... does that for any browser. And that's it for the unique features as far as I'm concerned. One is slow, single-threaded and lightweight-ish (Midori) and another has vim keybindings in an application that shouldn't (Luakit).
Pretty much all of them use webkit2gtk as their engine, and pretty much all of them launch a separate process for each tab. People say this is more secure, but I have serious doubts about that. You're still running all these processes as the same user, and they all have full access to the X server they run under (this is also a criticism against user separation on a single X session in general). The only thing it protects against is a website crashing the browser, where only that tab and its process would go down. Which.. you know.. should a webpage even be able to do that?
But what annoys me the most is the sheer amount of memory that all of these take. With all due respect all of you browsers, I am not quite prepared to give 8 fucking gigabytes - half the memory in this whole box! - just for a dozen or so tabs. I shouldn't have to move my web browser to another lesser used 16GB box, just to prevent this one from going into fucking swap from a dozen tabs. And before someone has a go at the add-ons, there's 4 installed and that's it. None of them are even close to this complete and utter memory clusterfuck. It's the process separation. Each process consumes half a GB of memory, and there's around a dozen of them in a usual browsing session. THAT is the real problem. And I want to get rid of it.
Browsers are at their pinnacle of fucked up in my opinion, literally to the point where I'm seriously considering elinks. Being a sysadmin, I already live my daily life in terminals anyway. As such I also do have resources. But because of that I also associate every process with its cost to run it, in terms of resources required. Web browsers are easily at the top of the list.
I want to put 8GB into perspective. You can store nearly 2 entire DVD movies in that memory. However media players used to play them (such as SMPlayer) obviously don't do that. They use 60-80MB on average to play the whole movie. They also require far less processing power than YouTube in a web browser does, even when you download that exact same video with youtube-dl (either streamed within the media player or externally). That is what an application should be.
Let's talk a bit about these "complicated" websites as well. I hate to break it to you framework web devs, but you're a dime a dozen. The competition is high between web devs for that exact reason. And websites are not complicated. The document itself is plain old HTML, yes even if your framework converts to it in the background. That's the skeleton of your document, where I would draw a parallel with documents in office suites that are more or less written in XML. CSS.. oh yes, markup. Embolden that shit, yes please! And JavaScript.. oh yes, that pile of shit that's been designed in half a day, and has a framework called fucking isEven (which does exactly what it says on the tin, modulo 2 be damned). Fancy some macros in your text editor? Yes, same shit, different pile.
Imagine your text editor being as bloated as a web browser. Imagine it being prone to crashing tabs like a web browser. Imagine it being so ridiculously slow to get anything done in your productivity suite. But it's just the usual with web browsers, isn't it? Maybe Gopher wasn't such a bad idea after all... Oh and give me another update where I have to restart the browser when I commit the heinous act of opening another tab, just because you had to update your fucking CA certs again. Yes please!19 -
I kinda hate how even if people submit good and useful code to OSS repositories, you need to act like a salesperson if you want anyone to notice/care about it

fork() can fail: this is important
Ah, fork(). The way processes make more processes. Well, one of them, anyway. It seems I have another story to tell about it.
It can fail. Got that? Are you taking this seriously? You should. fork can fail. Just like malloc, it can fail. Neither of them fail often, but when they do, you can't just ignore it. You have to do something intelligent about it.
People seem to know that fork will return 0 if you're the child and some positive number if you're the parent -- that number is the child's pid. They sock this number away and then use it later.
Guess what happens when you don't test for failure? Yep, that's right, you probably treat "-1" (fork's error result) as a pid.
That's the beginning of the pain. The true pain comes later when it's time to send a signal. Maybe you want to shut down a child process.
Do you kill(pid, signal)? Maybe you do kill(pid, 9).
Do you know what happens when pid is -1? You really should. It's Important. Yes, with a capital I.
...
...
...
Here, I'll paste from the kill(2) man page on my Linux box.
If pid equals -1, then sig is sent to every process for which the calling process has permission to send signals, except for process 1 (init), ...
See that? Killing "pid -1" is equivalent to massacring every other process you are permitted to signal. If you're root, that's probably everything. You live and init lives, but that's it. Everything else is gone gone gone.
Do you have code which manages processes? Have you ever found a machine totally dead except for the text console getty/login (which are respawned by init, naturally) and the process manager? Did you blame the oomkiller in the kernel?
It might not be the guilty party here. Go see if you killed -1.
Unix: just enough potholes and bear traps to keep an entire valley going.

Fake or not I think all HR should learn to be straightforward by saying "I'm sorry you're not qualified" rather than telling people "We will get back to you"
600years from that time, it's unlikely they will get back to you.
save us the stress dickheads!8 -
My new clothes washer has an app.
Neat!
The app requires location information or it won't start...

What you're about to read is an horror story based on real facts.
Our story begins one week ago, when a dev who calls himself "Arfmann" (what a loser, the f* means arfmann?) decided to take his dev skills to another level.
He always has been scared of databases. He made really bad dream about them. Like, they were screaming at him "SELECT useUs FROM database" while he was crying in some shared preferences noises.
A week ago, he decided to overcome his fear. He learned the basics of SQL. Everything was going well. Until, he decided to implement it on Flutter. A Google's technology.
At first, he decided to appeal to documentation. Went on Flutter web site. Flutter documentation. Sqflite documentation. Started reading. Started doing tests with the code written by Google's engineer.
Everything was fucked up. Dozens of errors, the documentation started to blow up and his PC went on fire, due to Android Studio.
He used a sample project made by Google's engineer. "Maybe if use directly their code it will work. Maybe I was the problem". He wasn't.
The whole documentation was wrong, every single line of code was a spaghetti code (yes, every single line was an entire spaghetti code). Everything was put in the main. If you wanted to try to keep things organized, you would end up punched and beaten up from the code itself. It would become a sentient entity that will beat you the fuck up.
Really scary.
