Dealing with React's setState and looking through all the possible lifecycle methods was so frustrating today.
It should have been a simple thing to disable a button, via the disabled prop, on click. I thought it would be enough to say
this.setState({ disableButton: true });
someSynchronousCode();
this.setState({ disableButton: false });
in the handler ... but it wasn't. The button would still be active for about a second after clicking. I tried several things like converting the synchronous code to a promise, trying componentDidUpdate with a comparison. It all failed. Interestingly enough removing the 2nd setState immediately disabled the button, though making it permanent.🙄
I've found a solution which seemed a bit hacky, changing the state back depending on another variable in the render method.
It seems so wrong, but it was the only solution I found after several hours.

A weird thing happened when I tried to install linux mint on my PC.
Although I installed it on a hard drive (I have another hard drive for windows), my bios tells me that Linux would be on the same hard drive as Windows?? I can assure that it's not the case, as I plugged out the linux drive and grub couldn't boot Linux anymore, just windows. Plug back in, linux bootable. Ok fine?
When I installed linux I panicked for a moment, as I thought I had it correctly installed separately, instead it would have become a dual boot, according to the bios?

More a positive rant...
Just casually looked into an invitation to a collab tool my workplace set up for discussing optimizations of workflows, internal collabs, communication, yada yada...
Just to figure out, that there's A LOT of room for improvement being discussed and new ideas related to our work. Which is fucking great! Like "Hey we could maybe introduce A/B testing for our software" or "We should change the way our CI/CD works".
One of the best things I've seen so far: "We should do smth about (react) component XY, as it currently holds many configurable parameters for look and feel with too many possibilities" ... these components are like each 1 big file or so, that covers EVERY possibility. I had a feeling in my gut that some things were built quite complicated, but originally with a good idea/intention in mind. I thought that I just needed time to get used to new things. Now I know that I need to learn nevertheless but that things NEED improvement and that others agree on that, too.
I think this is a good sign when a company tries to reflect on itself to become better.

Tldr: fucked up windows boot sector somehow, saved 4 months worth of bachelor thesis code, never hold back git push for so long!

Holy jesus, I just saved my ass and 4 months of hard work...
I recently cloned one of my SSDs to a bigger one and formatted the smaller one, once I saw it went fine. I then (maybe?) sinned by attaching an internal hdd to the system while powered on and detached, thinking "oh well, I might have just done smth stupid". Restart the system: Windows boot error. FUCK! Only option was to start a recovery usb. Some googling and I figured I had to repair the boot section. Try the boot repair in the provided cmd. Access denied! Shit! Why? Google again and find a fix. Some weird volume renaming and other weird commands. Commands don't work. What is it now? Boot files are not found. What do I do now? At this point I thought about a clean install of Windows. Then I remembered that I hadn't pushed my code changes to GitHub for roughly 4 months. My bachelor thesis code. I started panicking. I couldn't even find the files with the cmd. I panicked even more. I looked again at the tutorials, carefully. Tried out some commands and variations for the partition volumes, since there wasn't much I could do wrong. Suddenly the commands succeeded, but not all of them? I almost lost hope as I seemed to progress not as much as I hoped for. I thought, what the hell, let's restart and see anyway. Worst case I'll have to remember all my code😅🤦.
Who would have thought that exactly this time it would boot up normally?

First thing I immediately did: GIT PUSH --ALL ! Never ever hold back code for so long!
Thanks for reading till the end! 👌😅

I was stuck for almost 2 weeks on a button that would display, given a certain icon, and that would not display if it was another icon, although I checked the icons multiple times to make sure they existed.
A asked a co-worker for help. He looked at my code, couldn't figure out either. Called a 3rd co-worker. He looked at my code. "Yeah, seems right? ... Wait a second!" He found the problem.
... One FUCKING TYPO I had always overlooked, that was the name of the icon. 🤦

Proud to finally be another supporter of devRant. I've made myself a promise (no pun intended) to support devRant as soon as I begin to earn some money as a dev. So here I am...
Thank you dfox and trogus for your work!

Fuck, I knew that my code for my thesis would at some point become bad and very unmaintainable. Workaround here and there, everything put together "to fix later", just to make it all work "for now". I know what my code does where and when but my tech debt has reached a critical point, where a new idea and new procedure cannot be simply be added. Well, time to refactor and modularize as much as possible😪
Wish me luck that the whole project doesn't brake. Oh and of course so many different changes that I don't know what to put in git and in which order to do so.

When you realize that your company's git doesn't support smth like emailing or notifs, when commenting on bugs/merge requests/etc. and you manually have to tell those ones via other channels, that you just wrote smth/responded to them.
As a co-maintainer of a personal project I feel spoilt now, for having this functionality for free, but ... oh dear

Python working non-deterministic on VSCode? That just happened ... somehow, wtf??
Getting a list from a method and comparing its last element with an int value. Always worked before like a charm, didn't change a thing. All of a sudden TypeError, cannot run anymore? Restart VSCode, run again, still not running ... ?? Retry and print the element, in case I've surprisingly actually been an idiot all along ... nope, value looks in print as expected. Continue execution, suddenly condition works again. WTF just happened??? Caching, python extension bug, anything like that to blame?

Gotta love it when your untouched code worked just hours ago locally and now you have no idea why everything breaks, what has gone wrong and how to fix it ... but it's stable remotely on dev/test/live. Project runs on localhost + vpn on company servers. I can dynamically change the parts that shall be compiled locally and the rest will be loaded from the company servers.
Fucking great.

Needed to convert a collection of .avi videos to .mp4. Online converters only allow 1-2 videos at a time, with slow uploads, so no option.
Can't find a program that quickly fulfills my needs. Interesting ... 🤔
Look for python and a quick and dirty solution, ffmpeg and subprocess it shall be then.
Install ffmpeg, run subprocess with ffmpeg, put it inside a for loop, iterate over all videos with their respective number. Done.
3 lines of code, saved some time.
It's great to be a developer (sometimes).😏

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.

Jira on Android 🙄
I had an overview of the backlog, blocked, active issues, could see who works on what and so on ...
Accidentally pressed the back button, returned to the project. Now it's a single big list with only issue type, description and deadline. It's pretty much a guessing game, which feature is open. Their seems to be no way to change that, not even deleting any data.
How did this happen?? Let me change it back!

When the work laptop costs as much as your own PC (1100€), but holds twice the amount of RAM (32GB), has a webcam built in and a fingerprint scanner...

Since a friend of mine owns a domain for an open-source project and manages pretty much everything, including dealing with a db for registered accounts, I'm currently not really able to help when it comes to UI/UX things and frontend, besides the "main editor", which is like the core functionality of the project. I would like to set up smth like docker (on Windows 10 home, which is already not suitable, great start🤦) for some kind of pseudo-db all inclusive functionality thingy to be able to run a working example locally. Also a goal would be to switch to Typescript, include testing, to use webpack and to automate as much as possible.
Sad part is, I don't even know where to start and I'm also 100% sure that I will do almost everything wrong from research to implementation.😐

Feeling the need to know everything about web dev (frontend for now) already yesterday, though not having a clue, what to look at first, as it's its own universe. Everything has a million ways of implementation, combination and features worth looking at.
Already have worked with basic HTML, CSS and JS, had a short look a Typescript, being confronted with React Typescript + Redux + thunk, SASS, learned some basics of all.
Feeling lack of motivation to build smth to learn, yet I want to explore. Afraid to get stuck in tutorial hell, although I know, changing smth here and there in the projects is a must for learning. Feeling the lack of understanding the bits and pieces of what can be styled with CSS in which way. Understanding how npm, webpack, the strange parts of JS, ES6, work.
So ... freaking ... much ....

Me using numpy.polyfit() to fit a function to some data. Blame polyfit for not being accurate, search the web to find any related problems, as the polynom doesn't fit at all. Polynom is of 2nd degree, polyfit becomes unstable at about degree 20?? Try Polynomial.fit() ... same results. How can they all be wrong???See a little typo in my code, calculating the polynom points. Fix it, everything works.... wasted 2 and a half weeks because of this error.🤦🤦

Learning React and Redux for work ... fucking hell Redux is a lot to set up! (But easy to extend 🤔)

Trying to switch from 2 finger bird-view typing to 10 finger no-view. Fuck this is hard! I'm just veeery slowly getting used to it, although I tend to fall back automatically when I don't focus on it and just want to type in a few characters.
I keep doing several typos and often forget where a key was exactly or confuse the position of some character, even though I typed it fairly often before. Also typing any number or non-alphabetic letter is mostly a wild guess of finger position.
Either I'm a very slow learner or smth's wrong.😪

God damn it!
Tried to use scipy's UniveriateSpline on some (x,y) coordinates that I have and it throws errors because I have multiple x values with different y value. UniveriateSpline expects all x values to be incresasing. Problem is I want to use these values, otherwise the result might be different than expected. B-Splines shouldn't be dependent on this condition or have I missed something in my studies? Documentation doesn't tell me anything.🙄

I remember when I was in elementary school, there was a teacher, who taught me and 3 other kids, how a PC works and how to use it. He booted it up and told us that it would take quite some time before interaction was possible (a few minutes?). He described it as a person that just got up. It would first stretch, get some breakfast, so on and so forth.... those memories😌😁😅
Today I know that the hard drive and the CPU (and the other internals) were just fucking slow...😂

Does anyone know a good GUI-based file search program similar to "search everything" on windows? That program is fucking awesome! Web search has given me ANGRYSearch, which comes close but has some usability problems. Is there yet a better program I haven't discovered yet?

When the domain you want to buy has been taken from a domain-dealer who takes ownership of unused domains. When that dealer sells it for more than 10.000€ but also would accept ... 70€?🤔 When you see that the offer decreases automatically a couple 100€ every once in a while. Let's see how cheap it can get ...

Wasted 5 hours to implement video recording with cv2 in python. Followed the tutorials and searched SO for help. The video file I need to produce just doesn't get produced. It's a camera stream from ROS. Yet no errors that might help. Or even any errors. Thanks.

It's for my bachelor thesis. Fuck.

Soo I've written some python code to test things for my soon starting bachelor thesis. I work with a little robot car I share with other people and use 2 cameras on it. Today I make the extra effort to go to the lab to test my things as there were too many people busy with the available cars yesterday.
Set it all up with ROS and my project as per usual just to see whether python fucks me over again ... nothing, ok what a surprise.
Good part: my python code seems to work flawlessly
Bad part: cameras don't work, although they don't throw any errors. Quick check with rqt_image_view ... everything seems fucked up, but not broken. Cameras not accessible as they should be, only 1 view available instead of the normal million modes and a blank grey camera stream on the screen. But no errors, nothing.🙄😪

I also wanted to capture some footage to test at home, well that's gone to shit. Now I had to simulate that using my phone camera ... while crouching.
Fuck ... me.

There a times I love python for its quick way of writing things. But there are more times that python makes me angry or just frustrates me with its indentation logic.🤪
When the indentation in my project lets the code either accidentally run a million times more or a tab/spaces inconsistency that no tool warns me about except runtime error.
What about a language that combines pythons easy way with brackets on top?😪 I guess it already exists?😅
For my project C++ would be a viable alternative, but so far the language seems very weird to write.

Is it just me, that when tapping a rant on mobile the UI marks multiple list items as "selected", although only the one a actually tapped is opened?
It happens within the time I've written this, independently of app restart and it randomly highlights multiple rants below the selected rant, like a connected group of rants.
Anyone an idea?

Found this beautiful piece of code, that I wrote apparently a year ago .... oh my 😂 🤦‍♂ 😅
If I could travel back in time, I would would slap myself for doing this. Although I remember, why I did this, because of many min()/max() operations that I needed. I wanted to keep the code, so that I would know, which code piece belonged to which part, but man ... is that badly written! Nowadays with Clean Code style, I would certainly do it differently.

so FUCKING GREAT when you work on a git project in eclipse...🙄
git bash shows only 1 file that I've edited, eclipse ... shows a whole bunch of files that are even commited and pushed a long time ago. WTF??🤪

In javascript, is there a difference between separate function calls that mimic a "chain pattern" or state changes using if/else if/else and using the chain or state pattern directly? The internet gave me no real/helpful response to that.

Suppose that:
if(isThingA(thing)) {
makeThingB();
else if(isThingB(thing)){
makeThingC();
else {
makeThingA();
}

That code is always executed e.g. after a user mouse click. "thing" gets defined in some other code.
It can be seen as a state machine that goes back to its starting point.
Is a pattern with objects/classes/prototypes even needed/preferred instead?
It's partly a problem I'm facing in my code but it's also interesting to know ideas/thoughts on this.
