LONG RANT AHEAD!
In my workplace (dev company) I am the only dev using Linux on my workstation. I joined project XX, a senior dev onboarded me. Downloaded the code, built the source, launched the app,.. BAM - an exception in catalina.out. ORM framework failed to map something.
mvn clean && mvn install
same thing happens again. I address this incident to sr dev and response is "well.... it works on my machine and has worked for all other devs. It must be your environment issue. Prolly linux is to blame?" So I spend another hour trying to dig up the bug. Narrowed it down to a single datamodel with ORM mapping annotation looking somewhat off. Fixed it.
mvn clean && mvn install
the app now works perfectly. Apparently this bug has been in the codebase for years and Windows used to mask it somehow w/o throwing an exception. God knows what undefined behaviour was happening in the background...
Months fly by and I'm invited to join another project. Sounds really cool! I get accesses, checkout the code, build it (after crossing the hell of VPNs on Linux). Run component 1/4 -- all goocy. run component 2,3/4 -- looks perfect. Run component 4/4 -- BAM: LinkageError. Turns out there is something wrong with OSGi dependencies as ClassLoader attempts to load the same class twice, from 2 different sources. Coworkers with Windows and MACs have never seen this kind of exception and lead dev replies with "I think you should use a normal environment for work rather than playing with your Linux". Wtf... It's java. Every env is "normal env" for JVM! I do some digging. One day passes by.. second one.. third.. the weekend.. The next Friday comes and I still haven't succeeded to launch component #4. Eventually I give up (since I cannot charge a client for a week I spent trying to set up my env) and walk away from that project. Ever since this LinkageError was always in my mind, for some reason I could not let it go. It was driving me CRAZY! So half a year passes by and one of the project devs gets a new MB pro. 2 days later I get a PM: "umm.. were you the one who used to get LinkageError while starting component #4 up?". You guys have NO IDEA how happy his message made me. I mean... I was frickin HIGH: all smiling, singing, even dancing behind my desk!! Apparently the guy had the same problem I did. Except he was familiar with the project quite well. It took 3 more days for him to figure out what was wrong and fix it. And it indeed was an error in the project -- not my "abnormal Linux env"! And again for some hell knows what reason Windows was masking a mistake in the codebase and not popping an error where it must have popped. Linux on the other hand found the error and crashed the app immediatelly so the product would not be shipped with God knows what bugs...
I do not mean to bring up a flame war or smth, but It's obvious I've kind of saved 2 projects from "undefined magical behaviour" by just using Linux. I guess what I really wanted to say is that no matter how good dev you are, whether you are a sr, lead or chief dev, if your coworker (let it be another sr or a jr dev) says he gets an error and YOU cannot figure out what the heck is wrong, you should not blame the dev or an environment w/o knowing it for a fact. If something is not working - figure out the WHATs and WHYs first. Analyze, compare data to other envs,... Not only you will help a new guy to join your team but also you'll learn something new. And in some cases something crucial, e.g. a serious messup in the codebase.11 -
Teacher: Homework for next time is to make 2 web pages with three javascript.

Me: What's "three JavaScript"
T: undefined
M: Do you mean three files?
T: No, I mean three JavaScript.
M: Okay, so let's go with five CSS and twelve HTML as well then...
Please, go somewhere else when you can't explain your OWN HOMEWORK ASSIGNMENT. Holy fuck.18 -
StackOverflow: let's marginalize your "problem" and focus on the real issue at hand, which is that line 4 doesn't conform to the language standards and thus will lead to undefined behavior on a single kind of 8-bit microcontroller made in 1984 that is no longer in use.6

IF LIVES DEPEND ON A SYSTEM
1. Code review, collaboration, and knowledge sharing (each hour of code review saves 33 hours of maintenance)
2. TDD (40% — 80% reduction in production bug density)
3. Daily continuous integration (large code merges are a major source of bugs)
4. Minimize developer interruptions (an interrupted task takes twice as long and contains twice as many defects)
5. Linting (catches many typo and undefined variable bugs that static types could catch, as well as a host of stylistic issues that correlate with bug creation, such as accidentally assigning when you meant to compare)
6. Reduce complexity & improve modularity -- complex code is harder to understand, test, and maintain

A lite story about how i was hired at 16 years old.
Me at 11. Modifying HTML templates to create a sign up page for a game. Me at 14. Created some worthless websites in the past (at a training), barely knowing the structure of HTML.
Me at 15. Made my first website for a customer (using WordPress for the first time, didn't know how to use it before). The website was selling apartments, it was looking very good and went on the first place on SEO. Got my first money (100E).
Me at 16. Made some other WordPress websites for other customers (one of them still haven't paid, the website was made way back in 2015), so i shut down the website and replaced it with a text saying "This website is currently down until the customers pays the developer".
Me still at 16. A friend of my mom sent my CV to multiple companies, to work as a intern to learn more, and one of them accepted me for a interview (a well known and one of the best company with 30~ people)
Went to the interview, asked me about what i realized, what i can do, about my knowledges in others languages etc (forgot to mention that i love the computers from young age, so i was very good in them, specially at the age of 11), so they were happy about it and asked called me for another interview with the boss. Went to it, the boss asked me some tricky questions, i answered them immediately, he was very surprised about my knowledge at that age and accepted me immediately. After working for 2 weeks, instead of hiring me as a intern for 4-6 months, they instead hired me as a normal person, as a front end developer, for an undefined date, making 250 E / Month (6 hours per day in summer)
Now, I'm in the 11 grade, working for them about 9 months, making 315 E / Month, working for 4 hours per day after school, the place is cool, my entire team (family) is very funny and very cool, and they asked me many times to help them with different problems they had and i fixed them immediately (they really didn't know some stuff which i knew). Worked on big projects and worked on some from scratch by myself and they were very happy about how it went.
TLDR: was talented in computers (software), I'm a fast learner, barely knew about making websites, hired as a front end developer at 16 yr.
Btw, I'm in love with DevRant, I'm feeling like home everytime i visit this community :').
P.S. Sorry for my bad English and the mistakes i made.
alert("Thanks for reading my first rant!");10 -
This codebase reminds me of a large, rotting, barely-alive dromedary. Parts of it function quite well, but large swaths of it are necrotic, foul-smelling, and even rotted away. Were it healthy, it would still exude a terrible stench, and its temperament would easily match: If you managed to get near enough, it would spit and try to bite you.
Swaths of code are commented out -- entire classes simply don't exist anymore, and the ghosts of several-year-old methods still linger. Despite this, large and deprecated (yet uncommented) sections of the application depend on those undefined classes/methods. Navigating the codebase is akin to walking through a minefield: if you reference the wrong method on the wrong object... fatal exception. And being very new to this project, I have no idea what's live and what isn't.
The naming scheme doesn't help, either: it's impossible to know what's still functional without asking because nothing's marked. Instead, I've been working backwards from multiple points to try to find code paths between objects/events. I'm rarely successful.
Not only can I not tell what's live code and what's interactive death, the code itself is messy and awful. Don't get me wrong: it's solid. There's virtually no way to break it. But trying to understand it ... I feel like I'm looking at a huge, sprawling MC Escher landscape through a microscope. (No exaggeration: a magnifying glass would show a larger view that included paradoxes / dubious structures, and these are not readily apparent to me.)
It's also rife with bad practices. Terrible naming choices consisting of arbitrarily-placed acronyms, bad word choices, and simply inconsistent naming (hash vs hsh vs hs vs h). The indentation is a mix of spaces and tabs. There's magic numbers galore, and variable re-use -- not just local scope, but public methods on objects as well. I've also seen countless assignments within conditionals, and these are apparently intentional! The reasoning: to ensure the code only runs with non-falsey values. While that would indeed work, an early return/next is much clearer, and reduces indentation. It's just. reading through this makes me cringe or literally throw my hands up in frustration and exasperation.
Honestly though, I know why the code is so terrible, and I understand:
The architect/sole dev was new to coding -- I have 5-7 times his current experience -- and the project scope expanded significantly and extremely quickly, and also broke all of its foundation rules. Non-developers also dictated architecture, creating further mess. It's the stuff of nightmares. Looking at what he was able to accomplish, though, I'm impressed. Horrified at the details, but impressed with the whole.
This project is the epitome of "I wrote it quickly and just made it work."
Fortunately, he and I both agree that a rewrite is in order. but at 76k lines (without styling or configuration), it's quite the undertaking.

Amusing: after running the codebase through `wc`, it apparently sums to half the word count of "War and Peace"15 -
"Errors? Won't happen to me!"
One of my first jobs was to finish and maintain a program, that was made by a guy who had a real genius image among others. Years later, people said "oh him, that smart guy."
I never met him, but that's what i heard.
However, he was not only smart, but it seems he was also very confident. That's what i deduct from his code.
He didn't use catch-blocks. They were all empty. Not even logged.
If errors appeared , it was not possible to see what happened and where and why. The program would continue it's execution and if following steps could not work, because there had been an unnoticed exception, it would just throw another unnoticed exception and at some point, end in an undefined state.5 -
I hate all of these rants about JavaScript being a terrible language.
In reality, it's one of the easiest languages to work with. This makes it easier for new programmers to write messy code, but is it the language's fault?
People get mad about the things that happen when you multiply "undefined" and a string...what do you expect?
You also have the freedom to choose from a variety of tools the community has created to solve existing problems. People just don't realize that they don't *have* to learn everything, you just learn as you need them.
Don't blame JavaScript for you bad programming, terrible type conversion needs, and great tooling.24 -

I started two months ago a new role in a new company.
Together with 3 colleagues I manage a HUGE OpenStack platform (I’m talking about more than 300 customers, many petabytes of data, dozens of compute nodes 😍).
On Friday night a well-known multinational had the GREAT idea to update the software of one of the core components of the platform (Neutron).
Obviously it all went wrong and customers started to call and open tickets, so even if it was already past midnight we’ve been all called to arms.
As a workaround we had to rebuild ALL the networks, detach all the ports and reattach them to the VMs, with all the errors that came with this kind of operations, such as failing to get an internal/external IP, fail to boot etcetera.
What amuses me is the fact that the above-mentioned multinational just asked for logs with no solution (except for the above workaround) until Monday morning.
It has been a good weekend, i talked with professionals from all over the world, in various languages, and worked multi-tasking with two different computers, with a third that was used just to share my screen and VPN for the management network.
During this weekend I virtually met all the possible colleagues that I will meet in this new role, and it was pretty funny to see how they handle stress. (Badly if you ask)
I’ve been woken up at 7:30 after falling asleep at 6:45, I’ve slept 17 hours in 5 days, haven’t taken a shower in 5 days (I know, it happens, I worked from home) but it was worth it.
Not only and merely for the money (overtime work), but mainly for the job itself.
I love to handle this HUGE infrastructures for now, even if I think they have many limitations and many components could have been written better.
The best thing about this weekend was to meet a group of people from all over the country and the world that worked non-stop from Friday night until Wednesday night to solve the situation.
All of them understood me when I asked them questions, and didn’t treat me like the [insert random]science nerd that I am.
I felt like in the movies, in front of three monitors, working from the comfort of my chair, in my underwear, eating as fast as I could because I was constantly in call with someone.
Apart from that, WHAT THE FUCK WENT THROUGH YOUR HEAD TO DEPLOY AN UPDATE ON FRIDAY NIGHT, YOU FUCKING PIECE OF adorable man???
WHY COULDN’T YOU WAIT UNTIL MONDAY??? NOBODY USES THOSE SERVICES AT NIGHT APART FROM THE SCHEDULED JOBS!!!!!
I HOPE YOU’LL HAVE A LONG AND PROSPER LIFE, FULL OF JOY AND HAPPINESS7 -
I love Linux, but its community can be so full of incompetent assholes..
Just now I asked in Freenode ##linux how to get the process ID of my current running process in bash. I got my answer - it's a shell built-in called "$$".
Then people start to nitpick some more - why do you need it? How is that different from an exit? - to which my response was.. well I know the whole idea behind exit codes, and I'd use it whenever possible, in all defined behavior that allows my program to terminate itself whenever it can. This pidfile however would be used to exit itself and provide diagnostic information whenever the program enters undefined behavior - a segfault in C language. Scenarios in which I don't have full control over the script's behavior anymore, such as the system entering an unworkable state where the system stalled, still got some binaries in RAM but the rootfs got unwritable, such as now - very helpfully, thanks HP! - when my laptop likely overheated and shat itself. I issued sudo reboot into it, but even that wouldn't issue properly anymore due to the /sbin/poweroff binary becoming inaccessible too. I had to issue a hard power cycle.. one of the few times in which I'm thankful to HP for actually causing shit like this, lol.
Point is, that undefined behavior is what I'm trying to mitigate against. I certainly can't let any files other than diagnostics remain in nonvolatile storage like that, especially when their state should be predictable in order to ensure good operation (like files expressing whether the script is already running or not, i.e. lock files).
Back to that IRC chat. Aside from the answer, I got ridicule from people who probably don't even know how to properly compile a kernel. Ubuntu users, overconfident scum. Sometimes I feel like I should ask questions in channels like #archlinux only, where such incompetency is ridiculed on its own.14 -

Hey guys,
this rant will be long again. I'm sorry for any grammar errors or something like that, english isn't my native language. Furthermore I'm actually very sad and not in a good mood.
Why? What happened? Some of you may already know - I'm doing my apprenticeship / education in a smal company.
There I'm learning a lot, I'm developing awesome features directly for the clients, experience of which other in my age (I'm only 19 years old) can only dream.
Working in such a small company is very exhausting, but I love my job, I love programming. I turned my hobby into a profession and I'm very proud of it.
But then there are moments like the last time, when I had to present something for a client - the first presentation was good, the last was a disaster, nothing worked - but I learned from it.
But this time everything is worse than bad - I mean really, really worse than bad.
I've worked the whole week on a cool new feature - I've done everything that it works yesterday, that everything gets done before the deadline of yesterday.
To achieve this I've coded thursday till 10pm ! At home! Friday I tested the whole day everything to ensure that everything is working properly. I fixed several bugs and then at the end of the day everything seems to be working. Even my boss said that it looks good and he thinks that the rollout to all clients will become good and without any issues.
But unfortunately deceived.
Yesterday evening I wrote a long mail to my boss - with a "manual". He was very proud and said that he is confident that everything will work fine. He trusts me completly.
Then, this morning I received a mail from him - nothing works anymore - all clients have issues, everything stays blank - because I've forgotten to ensure that the new feature (a plugin) and its functionality is supported by the device (needs a installation).
First - I was very shoked - but in the same moment I thought - one moment - you've written an if statement, if the plugin is installed - so why the fuck should it broken everything?!
I looked instant to the code via git. This has to be a very bad joke from my boss I thought. But then I saw the fucking bug - I've written:
if(plugin) { // do shit }
but it has to be if(typeof plugin !== 'undefined')
I fucked up everything - due to this fucking mistake. This little piece of shit I've forgotten on one single line fucked up everything. I'm sorry for this mode of expression but I thought - no this can not be true - it must be a bad bad nightmare.
I've tested this so long, every scenario, everything. Worked till the night so it gets finished. No one, no one from my classmates would ever think of working so long. But I did it, because I love my job. I've implemented a check to ensure that the plugin is installed - but implemented it wrong - exactly this line which caused all the errors should prevent exactly this - what an irony of fate.
I've instantly called my boss and apologized for this mistake. The mistake can't be undone. My boss now has to go to all clients to fix it. This will be very expensive...
Oh my goodnes, I just cried.
I'm only working about half a year in this company - they trust me so much - but I'm not perfect - I make mistakes - like everyone else. This time my boss didn't looked over my code, didn't review it, because he trusted me completly - now this happens. I think this destroyed the trust :( I'm so sad.
He only said that we will talk on monday, how we can prevent such things in the feature..
Oh guys, I don't know - I've fucked up everything, we were so overhelmed that everything would work :(
Now I'm the looser who fucked up - because not testing enough - even when I tested it for days, even at home - worked at home - till the night - for free, for nothing - voluntary.
This is the thanks for that.
Thousand good things - but one mistake and you're the little asshole. You - a 19 year old guy, which works since 6 months in a company. A boss which trusts you and don't look over your code. One line which should prevent crashing, crashed everything.
I'm sorry that this rant is so long, I just need to talk to you guys because I'm so sad. Again. This has happend to frequently lately.16 -
In my first summer at my internship I was fixing up a PHP script that a previous developer wrote... It collected our customer's emails and sent them to MailChimp for marketing.
The SQL query to get the emails was pretty standard, but what he did next was not.
There were for loops nested 3 deep. The outer loop's counter was i. The inner was ii. And the deepest was iii. That alone made it hard to read, but for a couple years some iii's and ii's were mixed up when getting values for arrays. So it was even harder to tell what it was supposed to do.
The inner loop also started at i-20. This was so he could look through and see if an email was already included from that query and skip it. But he didn't check the bounds, so the first 20 times through the outer loop, the inner loop would throw `undefined index -20` errors.
In order to fix all this I did an order by on the query, and kept a last email variable that I used for comparison. Pretty basic. This also lowered it to just one loop.
I talk about it on a regular basis with my coworkers and we all laugh about it. I also bring it up when upper management thinks they can code, because that ex developer is now an executive. -
Use profanity labelled variables... like the $penis I just used in my code... (makes coding fun, until u get "undefined variable: cannot find $penis on line 31")1

My Sunday Morning until afternoon. FML. So I was experiencing nightly reboots of my home server for three days now. Always at 3:12am strange thing. Sunday morning (10am ca) I thought I'd investigate because the reboots affected my backups as well. All the logs and the security mails said was that some processes received signal 11. Strange. Checked the periodics tasks and executed every task manually. Nothing special. Strange. Checked smart status for all disks. Two disks where having CRC errors. Not many but a couple. Oh well. Changing sata cables again 🙄. But those CRC errors cannot be the reason for the reboots at precisely the same time each night. I noticed that all my zpools got scrubbed except my root-pool which hasn't been scrubbed since the error first occured. Well, let's do it by hand: zpool scrub zroot....Freeze. dafuq. Walked over to the server and resetted. Waited 10 minutes. System not up yet. Fuuu...that was when I first guessed that Sunday won't be that sunny after all. Connected monitor. Reset. Black screen?!?! Disconnected all disks aso. Reset. Black screen. Oh c'moooon! CMOS reset. Black screen. Sigh. CMOS reset with a 5 minute battery removal. And new sata cable just in cable. Yes, boots again. Mood lightened... Now the system segfaults when importing zroot. Good damnit. Pulled out the FreeBSD bootstick. zpool import -R /tmp zroot...segfault. reboot. Read-only zroot import. Manually triggering checksum test with the zdb command. "Invalid blckptr type". Deep breath now. Destroyed pool, recreated it. Zfs send/recv from backup. Some more config. Reboot. Boots yeah ... Doesn't find files??? Reboot. Other error? Undefined symbols???? Now I need another coffee. Maybe I did something wrong during recovery? Not very likely but let's do it again...recover-recover. different but same horrible errors. What in the name...? Pulled out a really old disk. Put it in, boots fine. So it must be the disks. Walked around the house and searched for some new disks for a new 2 disk zfs root mirror to replace the obviously broken disks. Found some new ones even. Recovery boot, minimal FreeBSD Install for bootloader aso. Deleted and recreated zroot, zfs send/recv from backup. Set bootfs attribute, reboot........
It works again. Fuckit, now it is 6pm, I still haven't showered. Put both disks through extensive tests and checked every single block. These disks aren't faulty. But for some reason they froze my system in a way so that I had to reset my BIOS and they had really low level data errors....? I Wonder if those disks have a firmware problem? So that was most of my Sunday. Nice, isn't it? But hey: calm sea won't make a good sailor, right?6 -

Did a bunch more cowboy coding today as I call it (coding in vi on production). Gather 'round kiddies, uncle Logan's got a story fer ya…
First things first, disclaimer: I'm no sysadmin. I respect sysadmins and the work they do, but I'm the first to admit my strengths definitely lie more in writing programs rather than running servers.
Anyhow, I recently inherited someone else's codebase (the story of my profession career, but I digress) and let me tell you this thing has amateur hour written all over it. It's written in PHP and JavaScript by a self-taught programmer who apparently discovered procedural programming and decided there was nothing left to learn and stopped there (no disrespect to self-taught programmers).
I could rant for days about the various problems this codebase has, but today I have a very specific story to tell. A story about errors and logs.
And it all started when I noticed the disk space on our server was gradually decreasing.
So today I logged onto our API server (Ubuntu running Apache/PHP) and did a df -h to check the disk space, and was surprised to see that it had noticeably decreased since the last time I'd checked when everything was running smoothly. But seeing as this server does not store any persistent customer data (we have a separate db server) and purely hosts the stateless API, it should NOT be consuming disk space over time at all.
The only thing I could think of was the logs, but the logs were very quiet, just the odd benign message that was fully expected. Just to be sure I did an ls -Sh to check the size of the logs, and while some of them were a little big, nothing over a few megs. Nothing to account for gigabytes of disk space gradually disappearing.
What could it be? I wondered.
cd ../..
du . | sort --sort=numeric
What's this? 2671132 K in some log folder buried in the api source code? I cd into it and it turns out there are separate PHP log files in there, split up by customer, so that each customer of ours (we have 120) has their own respective error log! (Why??)
Armed with this newfound piece of (still rather unbelievable) evidence I perform a mad scramble to search the codebase for where this extra logging is happening and sure enough I find a custom PHP error handler that is capturing (most) errors and redirecting them to these individualized log files.
Conveniently enough, not ALL errors were being absorbed though, so I still knew the main error_log was working (and any time I explicitly error_logged it would go there, so I was none the wiser that this other error-catching was even happening).
Needless to say I removed the code as quickly as I found it, tail -f'd the error_log and to my dismay it was being absolutely flooded with syntax errors, runtime PHP exceptions, warnings galore, and all sorts of other things.
My jaw almost hit the floor. I've been with this company for 6 months and had no idea these errors were even happening!
The sad thing was how easy to fix all the errors ended up being. Most of them were "undefined index" errors that could have been completely avoided with a simple isset() check, but instead ended up throwing an exception, nullifying any code that came after it.
Anyway kids, the moral of the story is don't split up your log files. It makes absolutely no sense and can end up obscuring easily fixable bugs for half a year or more!
Happy coding.5 -
I fucking hate non-values like null, undefined, nil, etc., but mostly how they are implemented in PHP and Javacript.
// PHP:
$null_array = array(null);
array_shift( $null_array ); // returns null, okay
$empty_array = array();
array_shift( $empty_array ); // also returns null – why?!
This effectively means:
array_shift($empty_arr) === array_shift($null_array); // true, what in the actual fuck?
// JavaScript:
[].shift() === [null].shift(); // false, because [].shift() === undefined
But still, if not checking for strict equality:
[].shift() == [null].shift(); // true
Strictly following this logic, [][0] (JS) and $empty_array[0] (PHP) shouldn't throw any errors and instead return equivalent values, but it happens, anyway.
% Erlang:
hd([blah). % blah
hd([]). % throws exception
# Elixir:
hd [nil] # nil
hd [] # raises exception
-- Haskell:
head ["blah"] # "blah"
head [] -- another exception
At least I've learned a few things. I'll stick to functioal programming for the future, and PHP and JavaScript are not only fucked up, they are fucked up beyond all recognition. Programmers think logically, my ass.10 -

Had a weird bug in a competitive workshop I just went to in which a variable was showing up in the debugger but was undefined when trying to be used in JS.
For those of you who don't know, there's a nondescript unknown bug in some languages where they can't set a variable until it has been read (i.e. must get before set). This is so rare it rarely happens but it sometimes does and can be solved by reading the variable. I actually only came across this issue a month ago randomly and had it explained by someone else.
So knowing this I said just console.log it and it'll be fine. Everyone laughs, but I'm dead serious. At this point they told me that this was noob and that they should post on here ranting about how I wanted to do print statement debugging. Was kinda annoyed so just let them do their things for a few hours.
Then the supervisor walks by and asks them why they're lagging behind so much. They explain the issue and clearly he's familiar with this bug but wants this to be a learning experience, so he says everyone should say what they think it could be after thinking a bit about it. My colleagues, being ever the assholes, tell me to go first so they can get more time, thinking that my BS print debugging won't do anything and just waste some time.
Lo and behold, one console.log later, bug is solved.
Think twice before shitting on print statement debugging 😜2 -

I read this in stackoverflow today:
Welcome to every C/C++ programmers bestest friend: Undefined Behavior.
There is a lot that is not specified by the language standard, for a variety of reasons. This is one of them.
In general, whenever you encounter undefined behavior, anything might happen. The application may crash, it may freeze, it may eject your CD-ROM drive or make demons come out of your nose. It may format your harddrive or email all your porn to your grandmother.

Was forced to do some work on Windows this week (CAD tools that runs only on Windows). I spent a few days just setting up the tools. There were quite a few things I realized I forgot about Windows (as compared to Linux).
1) Installation times are down right horrific. What exactly are the installer doing for 10 minutes?
2) .NET is a cluster fuck. Not even Microsofts repair tool can fix it, but rather just hangs. I ended up using another tool to nuke it and reinstall.
3) Windows binary installs are insanely huge, thus, takes forever to download.
4) The registry is a pointless database that must have been written in hell with the single intent of destroying users will to live. The sole existence of the registry is another proof that completely incompetent engineers designed Windows.
5) Rebooting is the only way to solve many problems. This is another sure sign of a fundamentally fucked up OS design.
6) What the heck is wrong with the GUIs designers? The control panel must be the worst design ever. There are so many levels to get to a particular setting I'm getting dizzy. Nothing gets better by the illogical organisation.
7) Windows networking. A perversion of the tcp/ip stack that makes it virtually impossible to understand a damn thing about the current network configuration. There are at least 3 different places that effects the settings.
8) Windows command prompt. Why did they even bother to leave it in? The interpreter is as intelligent as retarded donut. You can't do anything with it, except typing "exit" and Google for another solution.
8) Updates. Why does it takes hundreds of updates per month to keep that thing safe?
9) Despite all updates that is flying out of Redmond like confetti, it is still necessary to install antivirus to keep the damn thing safe. That cost extra money, and further cost you by degrading performance of your hardware.
10) Window performance. Software runs like it was swimming in molasses. The final stab in the back on your hardware investment, and pretty much sends performance on your hardware back a few hundred bucks more.
11) Closed source is evil. If something crash consistently, you might find a forum that address the issues you have. Otherwise you're out of luck. On the other hand, it might be for the better. I imagine reading the code for Windows can lead to severe depression.
I'm lucky to be a Linux dev, and should probably not complain too much... But really, Windows, go get yourself hit by a truck and die. I won't miss you.14 -

Code comments #1: A way to document bad code that wasn't reduced to it's essentials and thus unreadable. Bad.
Code comments #2: A way to explain for non-programmers how the code works. Wrong place.
Code comments #3: Company policy. No one really knows why, but others do that, so we better do it to. The management sucks.
Code comments #4: Because some hip methodology/guru describes how to document code. After a few years, when the methodology has been (unofficially) forgotten, everyone still comments the code the same way. The old management sucked.
Code comments 5#: For insecure programmers who want to convince them self they understand the code they've written. Maybe apply at McDo?
Code comments #6: Some programmers are apparently paid by lines of code. Possibly understandable.

I love javascript, but sometimes it's just an incredibly stupid language, such as when undefined variables get interpreted as string literal "undefined" when concatenating strings. I like it better how, for example, PHP handles undefined values, that nulls just turn into "". Better still: typed languages, where most stupid mistakes are caught already at compilation, instead of having to spend hours to track down where that mysterious "undefined" comes from. As I said, I love javascript - because it is easy to code, flexible and forgiving in many ways. But I hate it for the exact same reason, for being such a sloppy fluffy...thing, and a bugger to debug. If javascript would be an animal, it would be a cute and cuddly cat that you instantly find adorable, but it's actually quite fat and lazy, plus its fur is littered with ticks and other bugs.12

while a<n:
print a
a,b=b,a+b

Init Mud. (A poem)
A Giant Ball of Mud.
Haphazard in structure.
A sprawling, enthralling, duct-taped warning,
Of things to come.
Tumbling down a well-worn path
Of untamed growth and aftermath.
Into Spaghetti-code Jungle.
Where quick and dirty wins the day
And warnings spoken hold no sway
Or fall on deaf ears in the undergrowth.
Tumbling.
Gaining weight.
Bits stuck on.
Bytes taken out.
Patches,
On top of patches,
On top of obsolescence.
Hacked at, uploaded
All elegance eroded.
Made and remade
Then duplicated
Relocated
Refined and redesigned
Suffocated by expedient repair after expedient repair
The original self no longer there
Replaced by something
Unwieldy.
Design resigned to undefined
An architectural mystery
Whose function can no longer be
Seen or gleaned
From obfuscated in-betweens
Of classes
Made and remade
Duplicated.
Abused.
A squirming library of disused.
Pulled at, prodded, committed
Corners cut and parts omitted.
Bug ridden branches fused to a rotting core.
The structure...
The system...
The content...

A post today made me think about this interview I had about a year ago... I shall tell you all about it.
Went to a hiring event for this company everyone was cool but this one guy (who would have been my boss) was a total arrogant, douchey, know it all.
So anyways cue interviewing with him a week later. He says if I give you task A, B, C and they need to be done by the end of the week in which order do you do them. (Note: he literally said abc not actual tasks)
Me: I don't really know how to answer that question without more information.
Him: Well I like to see how people answer it... So think about it for a second.
Me: Ok I guess if doing one task would help me do the next task faster I would do it in that order. Like I can use code or concepts from C to do B faster.
Him: What if A would take 2 days and B and C would take 1 day.
Me: I don't see how that would influence the order I do them in.
Him: Would you complete one task after another or switch between them or do see simultaneously.
Me: It would depend on my previous answer and what would be the fastest way to get them done but without more info I literally cannot give you an answer of like I would do B, C, A.
Him: Would you do the longest task first or the shorter tasks.
Me: I don't know I guess it depends on if it would help you or somebody else move forward with something if I got a particular task or the shorter tasks done first.
So cue more of this kind of back and forth about arbitrary details about undefined theoretical tasks for like 10 minutes.
Suffice is to say I didn't get the job and I'm glad.7 -

During my first semester of CS we were mostly using MatLab for basal scripting - assigning variables, learning about scope, that type of thing. I was excited to start learning programming but wanted to actually make something rather than reversing arrays and incrementing counters for weeks.
I discovered the image() function which takes a float[][] matrix and displays it as an image. I generated my arrays of random numbers and made a simple nested loop where I iterated over each element, averaging it with its neighbours, and - it worked on the first run! I made a freaking noise and blur filter!
That rush of planning it out, making it, and seeing it work I think is my main drive in coding. All the hours of undefined-but-they-are-tho import paths and mystery segfaults are worth it once there is that moment of "it lives!". -
I was in dependency hell for two days.
Im a junior working in a team creating an ember app. Suddenly a main component refuses to work since an addon threw "EmberObject undefined"... Nobody could reproduce it and we where out of ideas, so I tried fixing it for 2days (7h total). I finally got it working after updating yarn :D
It never felt so good working again :) -
How to get your website reach out people with no advertisements!?
1. Once it's built, make another mock up by changing a few main highlighted words to "(null)" or undefined!
2. Then send the link to any person in the software development field, anonymously!

Note: don't forget to change the mock up with the original after u have sent the link!4 -

This is something that I hadn't done or that directly impacted me, but that had an effect in my life several years after it happened.
It's one of those stories that you think "this only happens to others", and then someday you're the "others".
So when I was born, I was, naturally, registered on the health care system. My parents chose an uncommon name for me (uncommon in my country) so I think I wasn't registered by the time of my birth, but 4 months later when all the bureaucratic crap came to an end (long story short, the guy that was there when it started died and my parents had to wait 4 months for another person to be appointed). So, when my parents finally went to register me, apparently, for some reason, the computer took my name and assumed it was a male name. As I've said, my name is uncommon in my country, there're probably 3 or 4 people with the same name here in Portugal.
Why did the computer assume it was a male name AND why didn't nobody check that? Since my parents had to ask to government entities to let them name me that name, I'm assuming it wasn't in their db. So why did it assume male? Was it purposely programmed that, by default, all "newly-registered" names were to be male? Was it random? Who the hell knows.
And how did nobody check that, every time I went to take vaccines? I don't think anyone told my mom that everytime we went there that the data was wrong, otherwise the situation wouldn't have lasted for 14 years.
We only knew about that mishap when it was time I had to take vaccines specifically for women and that I wasn't being noticed of it even though a friend 1y younger than me had already taken hers.
I find this story amusing but now that I started thinking about how it came to life (no pun intended) I'm actually a bit pissed off about how they didn't think of uncommon names and that how that could affect their registry in the system. They could have - IDK - placed "undefined" in that field so that it would caught the register's attention.
Moral of the story: don't assume stuff :v1 -

Why the actual FUCK does PHP not throw errors for undefined variables.

Installing CMS made simple on a FreeBSD machine turns out to be next to impossible.
I don't think this is related to FreeBSD, but PHP7.
All is working fine, all the apache stuff is done, PHP is installed with all dependencies, yet we have a call to an undefined function during the setup.
NOTHING with PHP is simple, EVER.
The whole language and environment is an absolute pile of turd, cobbled together into something vaguely resembling a working platform.
It makes Java look slick, and that's really saying something!!!
If there was ever a language that needed to be written off and totally take out of use, it's PHP.
There is nothing whatsoever about it which is in any way rational, usable, logical or sensible.
It's only triumph is that it runs on the cheapest web hosts, so it's ideal for anybody who values cash over quality.
People understand the cost of everything and the value of nothing, and given that PHP is a nightmare to work on, and pretty much NEEDS its error output to be stifled to prevent logs growing to excessive sizes, I would say PHP is, always has been and always will be an absolute failure of a language.
The fact that so much decent software has been written in it is not a testament to the language, but a testament to the tenacity of developers who have to get shit done, even with the worst tools imaginable.
The very fact that a framework is an absolute necessity to be able to get anything meaningful done speaks volumes about the poor design inherent in the language from the outset.
PHP is an abomination, and I feel nothing but sympathy for anybody who has no choice but to work with such a substandard pile of shit.14 -

Discord is now 3 years old, so people are making their avatars blurple (using a bot in python to make their avatars blurple AND THEN ABUSING IT AND WONDERING WHY ITS DOWN*)
So, I decided to do a learning experiment and see how hard it would be to create a simple webpage where you drag in an image, and it "blurpleifies" it for you, then you can right-click and save image as.
CSS filters are easy, but turning DOM elements into images..... not really.
domtoimage "worked" before, but my img tag was weirdly nested or something, and all hell broke loose. So I un-nested it and re-positioned it, DID NOT TOUCH "#final-color", AND I GET AN UNDEFINED!!!
I'm so done

How to run PHP in a container :
1. Begin a docker file for an existing php cron app (when all you know is php, everything looks like a php app)
2. Set the FROM.. Apt get update .. Do composer install
3. Builds the image
4. Discover I need git
5. Add git to apt get install step
6. Builds the image
7. Launch the php script
8. Fatal : use of undefined constant SOL_UDP
9. Opens the source code of the third party. The there's no mention of where that constant is from.
10. Spend many minutes online to find what's missing.
11. Find the PHP sockets page about that option. Digs into the documentation to find out that's missing from the installed PHP.
12. Find out I need to add a step to install the socket extension in my docker file.
13. Build the image again
14. Execute it, finally it works
15. Remember why I hate php
(for brevity I've omitted the even more complex part of having to set up zlib)

Focused on debugging Javascript after being asked for help. Original developer narrowed it down to an if statement. It was acting like the if statement was assigning the variable and causing undefined. Tested console.log before evaluation. Tried !== instead of != and same thing. Even swapped undefined and variable so it would try to assign a variable named undefined instead... It took way too long for the both of us to realize the word "let" in front of the variable on the line withing the if statement block... It overwrite the variable the moment it entered the block....

Spent the whole of yesterday working on it from 12a-midnight. Just this one feature to bring previous values into an edit page. Seems simple enough. But it wasnt working right. So im looking all over posted on SO even got a friend of mine thats been programming for 20 years to help me and we cant figure out why it thinks a variable is undefined when it clearly has a value dorectly before the save method fires. (Console.logged that shit)
At about midnight i realize its because i needed to write a router.put in the api because i was just using the regular save originally :/ -
So I have a MEAN app that is super simple just basic CRUD operations.
Everything works fine. Decide to extend it by bringing values over into fields on an Edit page. More work than I thought it would be but got it working, just passed values through an array in the URL. Pretty simple. So then I click save and it's broken. _id is apparently now undefined. Oh I posted it on the Javascript chat on SO and got nothing, instead everyone is talking about porn folders, a tweet, a random picture that looks like either a woman doing oral to a guy or a guy reading a book, and now Obamacare. FFS just answer my damn question >.< So I post it on SO itself and still crickets there. Worst part is I know its something simple I just don't know what it is because I'm still new to programming in general only been a few months in a bootcamp just learning the basics of MEAN stack (which I do like a lot tbh)
Man SO is so frustrating. -
{
regular: function () { return this }, // ok
arrow: () => { return this } // you mean undefined?
