Either I am dumb or the usage of p5.js functions makes it either hard or impossible to test with jest. Constructor properties are thrown away (which I need) and all methods are mocked, if I automock, or I've got the pleasure to mock everything inside the class. Otherwise of course jest complains that p5's color() isn't defined. And mocking everything manually is not safe in case of class changes.
Of course p5's tdd tutorial isn't helping, as it seems to mock everything.
I need like a pro/mentor or smth for this...

I finally created a kotlin android app for a simple project idea, just personal usage. Beginner level. Quite a good and bad experience.
Functionality is done, just sucks with UI, as I'm not proficient enough with styling on android.
The result is a predefined purple action bar at the top, an almost white text section right below it with *very* light-grey textview descriptions (you can guess how visible they are on my phone...). Center is a big recyclerview, which in android studio has white background with dark grey text items, yet is black on my phone with white text items. At the bottom 3 text inputs and a centered purple "add" button.
... It's a mess as long as you don't know how to design and style on android studio.

I have to go through roughly 700 data entries and adjust the system's data accordingly ... by hand.😑
We don't have the tools to automate this reliably, the only available tool, tells you that an error occured and what happened but not where. That would've been kinda helpful...
The problem is that the respective data object of the data entry often contains a phone number, which has to be in a standardized format ... which it is not. Every number is formatted in like 10 variations!? A dozen different separators like spaces, commas, slashes and hyphens. And it must be edited manually 😖
My solution: built a goddamn chrome extension to format the string on click. Done. Saves a few seconds each time and a lot of headache in future. Of course given the correctness of the extension.

Typical attempt to automate an annoying task, overengeneering more and more for hours, just to find out, that an iframe is blocking my way while searching the DOM. The iframe doesn't show me his descendants (did some research on that), hence the element I'm looking for cannot be queried, which was a main goal.
Great...

"Learning" kotlin for android dev has been a wild ride yet. Kotlin is kinda cool, a mix between python and Java but with many nice features. Then again there are kotlin features on which I just scratch my head like data classes and companion objects.
And then for android (not kotlin specific) I see things like calling Timepicker(...) or Timepicker Dialog(...) without assigning it to a variable and wonder how that can even work. Can someone explain? There's no creation method, static method or anything?
I feel like a competent and incompetent dev at the same time.

Tldr:
Can't fucking figure out why I'm the only one who can't solve a DP problem in code, when me and friends use the same idea and no one knows why only mine doesn't work...

We are given a task to solve a problem using DP. My friends write their code with the same idea as a solution. Copying the code is not allowed. I follow the same idea but my code won't work. Others look into it, in case they find errors. They can't find any.

The problem (for reference):
Given a fixed list of int's a = (a_1,a_2,...,a_n) and b = (b_1,b_2,...,b_n), a_i and b_i >= 0, a.length == b.length
We want to maximize the sum of a_i's chosen. Every a_i is connected with the b_i at the same index. b_i tells us how many indexes of a we have to skip if choosing the corresponding a_i, so list index of b_i + b_i's value + 1 would be the position of the next a_i available.

The idea:
Create a new list c with same length as a (or b).
Begin at the end of c and save a_n at the same position in c. Iterate backwards through c and at each position add the max value of all previously saved values of c (with regards to the b_i-restriction) with the current a_i, else a_i + 0 if the b_i-resctriction goes beyond the list.
Return the max value of c.

How does that not work for me but for the others?? Funny enough, a few given samples work with my code. I'm questioning my coding ability...

JS: adding new dom nodes by adding html markup to the innerHTML property as string...
It's either dumb or a genius move.

I thought I might give bootstrap a chance by recreating an existing website. Problem is that this website is "simpler" with a carousel and a dark mode toggle being the few more complicated features, so it might be even faster to simply write the CSS myself and get my hands dirty. Using bootstrap for this seems more and more overkill, the more I look at it. On the other hand I know bootstrap already takes much care of responsiveness and vendor-prefixes and so on. What have I gotten myself into with bootstrap...

Just tried some keyboard type practice. I'm stuck at around 30wpm (40 is average) and feel like I've hit a cognitive barrier. Whatever I do I mess up the R und T keys frequently as well as occasionally some other keys. I feel like a retard, as I sometimes need to rethink where the key is that I want to press, even though I've hit it like a thousand times before.
😪

I had to send in my bachelor thesis project in paper documents and also digitally ... on a CD. Probably bought one of the last CD packs in my life. Why does uni need this in 2020? What about usb?
I don't even have a PC with a CD-drive anymore. Everything is downloaded. I was lucky that there is still a laptop at home that has a drive.
Am I spoiled? Why are CD's still needed, except for games (maybe?)?

I have to write a text that explains the kalman filter and I'm expected to include some light technical details, too. I've just barely used it in its simplest form and have almost no understanding about the stochastic aspect of it. Also don't have much time left and I barely understand the simplest literature about it.
This is gonna be great. 🙃

When you want to investigate what a function does, you read the name and say "ok, seems reasonable what it should be doing" ... and then you encounter an adventure of if-else's, nested if's and else's, some promises here and there (with more nested if's and else's) and also a bunch of dispatches sprinkled all over the place. You want to refactor it into tinier functions but can't because you don't know what happens where ... help ... 🙄😩

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 🤔)
