“Any application that can be written in JavaScript, will eventually be written in JavaScript.” — Jeff Atwood

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 -

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.5

Today I was wandering through the code of the project I work on. The project is on JS, turns out someone named an object key `undefined`. They had the wonderful idea since they didn't want to pass a key through on the side where the info stored in the object is used(or at least that's what I assume).
Look at the image. (not the actual implementation but you get it and it actually works if you want to try it)
👏🏼 I don't know who did it and I rather not git blame it, but pray to the 7 gods you never do something like that again while I'm around or you are going to be in need of prosthetic fingers to code again motherfucker.

C has too much undefined behaviour because the standards comittee was being lazy and slapped that on a lot of issues that ought to have been implementation defined instead.

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?

Shamless rant towards the shamless Cursey dude. 😫
So whole day I have been trying to pass a variable from laravel blade view to vue2 component file. All in seperate files. I know that I have successfully passed 1 or 0 in same flow before.

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

The tons of undefined behaviour in C that ought to have been implementation defined instead, and increasingly sadistic compiler writers on the other side.
Like signed integer overflow that should just do what the underlying machine does, i.e. in practice, wrap around two's complement.
But the wierdest UB is when a C source code line has a non-matching ' or ". WTF, this should have been a compile time error!2 -

I just wasted 2 hours trying to figure out why the properties of a destructured object returned undefined, even though everything was fine in JSON format.

Turns out I used the wrong property names to access the info inside each object.

I don't understand some developer's thought processes when they fix a bug/issue.
Let's say the error is -> "Cannot read property id of undefined".
My first thought is to add a check for undefined and null and figure out if further code should be executed if a null or undefined is encountered, depending on what the code is supposed to do.
But some devs are like, "Yesterday the sunrise was at 5:30 AM, Earth's rotational axis is titled at 15 degrees to the left, My aunt asked me about how I am doing today, so therefore the bug fix is required at line 65,456 of this particular kernel file".
And they implement it, and it WORKS.

VirusTotal's API could do with a make over.
Though it is quite nice actually, you're able to provide them with a hash of a file and (provided they've scanned it) VT is able to tell you what up to 60 different virus scanners thinks about the file (and how many scanners that has an opinion about it). Now if there's an error, like the file not having been scanned or the hash being incomplete, it give you some JSON back where there will be an error message that tells you the error and an error code of 0.. wait wh
Although since it's an API they also need give us plebs whose only got access to an API key that limits us to 4 requests pr minutes. Naturally when you try to do another request within a minute of your limit the response you get is absolutely nothing what so ever. "" Naturally.
And of course the same response should be given when the API key you provide isn't valid. Who needs errors amiright?

I never said that whatever was inside the box was going to make it out... I just wanna get a good idea of what was inside.4

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.... FML.1

Got bored and decided to try and compile X11 Quake (WinQuake) so far trying to troubleshoot some undefined references

I expect somebody else has chosen this as well, but anyway:
Async.<any-function>, cause they brought me out of callback hell and taught me the undefined ways async...arghhhh fuck -
Problems with Dynamic typing (eyyy JS)

Working with Angular is like walking in a minefield.
Here, I get this ERROR in Cannot read property 'members' of undefined.
Of course, apparently stacktraces or clear error messages are optional for the Angular team.
Also, I looked for 'members' in my project. Hint, it's nowhere to be find.

An undefined ArrayList coupled with NullPointerExceptions because of it really know how to raise your blood pressure up.
Spent almost 1 hour trying to figure out why and all I needed to do was look a couple lines above.
But I guess that's what 4am development is all about -
Oh lord, may all GUI's come alive and eat their users, disintegrate their dev's and finally burst into flames and leave nothing but ashes.

Need some advise. I suggested a feature over an email to a CEO of a B$ company, he replied “we also have same idea in pipeline”, they developed it 3 years later. A lot of screens are same as I sent.
Can I ask for credit legally.14 -
Using void 0 instead of undefined is just ridiculous. Sure, you save 3 bytes but I've seen the code you write, you definitely should not care about that.7

try{
If(!res || typeof res == undefined || res == undefined){}

What the f*...
SomeType {
var something = {
somethingElse: "blah",
whatever: "halb"
}
var doStuff = function() {
this.something.whatever = "foo";
}
}
Based on what fucking logic are you claiming "something" is _undefined_ while running doStuff()??? What the fuck is wrong with you??? It's a freakin' static context!!!! "SOMETHING" IS DESIGNED TO BE DEFINED ! ! ! ! !8 -
How do you know that you are stuck in a job without longterm perspective (besides some undefined gut feeling)?
And what to do then? It seems to me, only possible action is to change job. Is there any, less extreme, alternative? -
Decided to try the beta build of WP 5.0 today to get a feel for Gutenberg block development, but it's not building confidence. Following the examples in the Handbook (Link: https://wordpress.org/gutenberg/...) and it's failing when trying to set up the rich text editor because apparently the object it relies upon is undefined. Been trying to track down the code for the basic paragraph box for an hour or so now so I can see how it's doing things, and haven't turned up anything useful.

since universe is expanding.
what was there in it before our universe reached there.
I think JS can answer this question.
it was 'undefined`
once our universe reaches there it becomes null.
its still nothing but no longer 'undefined'.10 -
Okay I always found these js weirdnesses that you see in memes more or less logical if you think about it, but so far I could not find any logic behind this:
true&&undefined
>undefined
false&&undefined
>false
can anyone explain wtf they thought about there? undefined is falsy so why not just convert it to boolean implicitly!4 -
Why the pointer of member function so special.
trying make a non-template class that like std::function but simpler:
1. wrap static function pointer.
2. wrap class member function pointer and the class object pointer.
3. WITHOUT ALLOCATE MEMORY.
I can't store member function pointer because the size is undefined?! -
Me: I found the problem. The function call is being given a reference to an undefined variable as an argument. The quotes around that argument were accidentally omitted; it's supposed to be a string.
A "Senior" Developer: No, that wouldn't cause it break.
Me: 😐3 -
So today I tried to code in c++ by separating class code into header and cpp file which I had not done before. Compiler was throwing error while compiling, "undefined reference to std::cout". Took me nearly an hour to figure out I was using gcc instead of g++.6

Only math would be so bold to use an undefined value/parameter name as the argument for a function. I gave it an Uncaught ReferenceError.

While building this site I decide to check if it works in internet explorer (you know, would be kinda nice) only to find out that apparently even edge does not support the js notation:
class MyClass {
// Stuff here.
}
Throws an exception 'MyClass' is undefined... Fuck you ie. Making me rewrite my damn classes.2 -
I know null is not undefined and there is a very good reason for that - yet I'm still surprised every time something behaves differently depending on which is used.1

Dear frontend dev,
if you can't check whether a variable is defined or not, why do i have to change the back end to accept urlparam='undefined' as valid and replace it with your default value in my backend? Why are you afraid of 40X's? You should be interested in the bugs of your code.
It feels awful to have a middleware in place catching all errors and replacing them with empty 200 responses 😭. All of this because you don't fucking ensure your variables exist before use.3 -

So, I have a problem I'm working with mongoose in nodejs and I want to make a dynamic query like I have 2 fields gender and type of room and these are optionals so what I did I wrote an if condition that if gender is not undefined a variable which is q += "gender:" + " ' " + gender + " ' " + ","; and when I pass this variable in find() it doesn't work but if i write the same query directly there in find() it works what seems to be the problem?1

You should leave undefined to the browser and keep null for yourself.
Don't '' var keep = undefined; ",
Do " var keep = null; "1 -

Javascript is my main tool at work right now, Typescript to be precise. It never ceases to amaze me, I guess as most of you.
What I've encountered recently still doesn't make sense to me but it seemingly works:
function a(){
someString && someFunction()
// other stuff ...
}
someString can be a string or undefined, someFunction can be a function or undefined.
How is that valid Javascript, without an assignment? Haven't found any explanation yet.22 -
Axios docs recommend me to use catch() callback for server error

Then in git issue someone told to provide error callback as second parameter in then()

I am using MERN to develop a poll app. I have 6 collections in my database. I have an API for each collection, 4 of those API returns the data whereas the other 2 return 'undefined'. What is the issue I am facing? Is MongoDB not allowing me to use more than 4 collections?6

Why in god's name does protobuf treat all enum values in the same scope??
Who would have thought that multiple enums may have values like "Undefined" or "Automatic"?
It's current year and somehow C style enums still haunt me1
