Fixing printers, business as usual.

Yeah fuck you, too...

Angular cli was installed globally with some "more up-to-date" version and locally for a project with a slightly older version. On a local machine. No problem.
The same thing on a VM: nope, module not found error. node trying to run a node_modules install script from within windows directory, in which nothing node-related exists ... ??

Don't expect requirements that will "never change, guaranteed" to actually "never change, guaranteed"

Isn't this (not my code) callback hell all over again? The 2. http call expects results from the 1. http call. I feel like this could be solved cleaner using async await/switchMap/etc. ... but not like this.

Why do any tutorials on any kind of technology start their projects on ports like 3000/8080/4200/5000 and so on? Why not start them on port 1/2/3/65536/etc.? Are these chosen tutorial ports free to use? Any special meaning? I've looked up a table of ports and many ports have a specific purpose but are still (mis)used for that arbitrary whatever project?

Having a senior DBA can save hours if not days of struggle and save your back, if you do not know well enough how to do a more complicated query yet, without fucking up something.
Good guidance and experience is worth so much.
... and no I do not have the rights to drop databases.

Used the java replace method to remove specific characters with a regex. Wondered, why the characters weren't replaced until I realized I forgot that replace doesn't use regex but matches literally. Checked my previous code snippets, whether I made that mistake previously ... nope, I used replaceAll. 🤦

rant & question
What am I supposed to do to finally get log4j working?? It just doesn't want to log in my project. Or it simply hates me. However many tutorials and documentation I've followed, even copy pasting simplest examples with ConsoleAppendet, setting the xml config to classpath.
It starts with default fallback logging.
How do all the tutorials automagically work??

Nobody thought about the scenario, where you received your vax certificate via pdf on your phone and wanted to register the qr code that was inside it? Like using a screenshot of the code or the pdf itself? The covid app on my phone demands to scan a qr code using my phone's camera. Understandable, if you receive the code on a piece of paper. But what about doing it this way too?

Glad that I've worked about 2½ days on an angular component, with all the struggles, brainstorming and meticulous care for "good" and "readable" code, just to find out that I misunderstood the requirements. Had to completely rewrite it...

Fucking remote db doesn't want to work with me and workbench. DB is on an empty test server, no firewall issues on the network, powershell on my pc says ping ok, tcp failing though, server firewall not running, server up and running.
Tried to modify network access on db configs like bind-adress, set my db user "host" value to wildcard. Now I can log in on workbench with my user, yet root somehow fails, wtf?
And of course once the connection is live, no db us visible, accessible, nothing works. I'm so frustrated. About to nuke it and restart ... again!

A file that I had copied from the company network drive into my own. VS Code to edit the content according to a tutorial provided. IDE doesn't work with the given file, dependencies not resolvable, so let's troubleshoot. Open the file in question inside the IDE, the file contents are those from the tutorial?? Turns out I didn't edit the file on my own system but on the network drive. At least it wasn't a critical file. 🤦

What was the idea behind java spring (jpa) and creating/using like a million annotations? There are annotations for literally everything...

I asked my former boss for some clarification via mail. Given a table, I was supposed to edit some user info in the company system. Had some questions on a few entries only my boss could answer.
Boss would organize a meeting, also inviting a more experienced co-worker I worked with. When the meeting starts, I get to know that my boss will join in a few minutes..... few minutes later, boss cancels the meeting. So it's me and the co-worker, who cannot answer my questions.
A simple mail could've solved it...

Struggled whole day to remove duplicate objects from a list in java. Those objects (of a custom class) contain a unique id, the remaining properties can be identical across list items.
Wondered why hashset.add() always returns true and thus duplicates are still inserted.
Little did I forget about things like equals() and hashCode() 🤦

Had my first vaccine yesterday ... today I'm a train wreck ... I hope your day is better.

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. Tried to request data on the frontend from my server with a database attached. Tried accessing each object of my array separately, it worked. In a loop: dataArray[index].propertyX ... undefined??
Turns out I used the wrong property names to access the info inside each object.
🤦

Probably acting. I loved to go to the acting course at school. Played a bigger role in a theatre play in that same school. I was more of a quiet guy, but had no problem turning into (most) roles and playing scenes.
Had a good friend who was part of a theatre club and passionate too, so working with him was even more fun.
My role-play seemed to be so impressive/surprising, that it was praised in the final year book by several anonymous comments inside my profile page.
Today I'm a CS grad and acting is still interesting, although it's unlikely that I will pursue this path.

Is there anything like a reverse search engine, that let's you enter e.g. some js code and it tells you what language feature has been used? Imagine you see syntax you've never used before and don't know what it's called or what it does but would like to know more about it.

Salesforce translation import tool is absolutely useless regarding error messages, when something is wrong with the file. Even if you try to replicate an already correct file, salesforce just tells you that something went wrong and which file formats are accepted ... even when using said format. No hints, no further explanation ... I need more details, WHAT IS WRONG?😠

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.
