I'm getting addicted to buying cheap electronic modules on AliExpress. Help me.

What would you check or look out for before choosing between multiple offers for a new job in software development?
I have multiple offers from different companies for a dual bachelor's degree.

Hardware Developing.

My current school project where I build a gps thief lock for my moped had me realized one thing. I don't want to go into Hardware Developing. The first problem took me about 4 months until I finally gave up and solved it differently. And this goes on and on and on. You fixed something and the next day it doesn't work anymore for some reason. I never had this problem when coding. It's fun to do stuff with electronics but coding is just way more rewarding. Anyone else had the same experience?

My dream Job Interview

Today I was interviewed by my dream company to work at. I'm still in school and it's an apprenticeship for computer science.

I had to develop a program, on a flip board which finds equilateral triangles. I was given a few points with coordinates on it and should think of something. I didn't get halfway through it.

Does anyone think that this is to much for an 17 year old still at school?

I'm so concerned that they don't take me because of this challenge.

SIM 800L
The fucking nail to my coffin. This thing is so unreliable. I fixed on issue get the next one. Then get an error trying to make a http request, with little information on the web. Eventually switch to FTP which is working for a while. Then suddenly nothing is working properly. Even the serial communication has errors. This process took over 6 months. Constant debugging and headscraching involved. After hundreds of hours I give up. I'm going to switch to a Raspberry Pi Zero with an UMTS Stick attached. This is going to cost way more battery time but my project needs to be finished by july and I'm tired of this shitty little module.

Fucking Linux tho

I started using Linux on a Raspberry Pi with Raspbian mostly accessing it over putty to install packages and running python scripts. I recently installed Debian Stretch with Raspberry Pi Desktop on an old Laptop to program in python because the package manager is so convenient.I really like the experience in using this none bloated os. Wanting to buy a refurbished Thinkpad to use as a daily driver it is really confusing which Distro to pick.
Just stay with Debian or is it worth to check out other distros?

Fucking german computer science classes

You get a few UML structograms and have to finish a half finished project. It's the most boring way to learn programming ever. Instead of giving us a task or a project to work on, it's literally translating UML to C#.

Is this what one is gonna do later as a software dev?

Code your own damn stuff!

I am building a RFID and button controlled music player for kids.
I am using a couple of different modules for that. The one for the input was really laggy. I thought it was so laggy because of the network delay. I tinkered with it a week but it didn't improved. So I just coded my own module which was much easier to do than I thought.
It was a really rewarding to code something yourself in less than a day instead of trying to get something working for a week.
