Resources

This site contains a list of resources I find and found helpful. I am not an expert in all of these topics, but all the resources listed here impacted me. I read some of the books quite a long time ago, so there might be newer editions out there already, and I might need to refresh some of the knowledge.

The list may not be exhaustive, but I will be adding more in the future. I firmly believe that educating yourself further is one of the most important things to advance. The lists are in random order and reshuffled every time (via *sort -R*) when updates are made.

You won't find any links on this site because, over time, the links will break. Please use your favourite search engine when you are interested in one of the resources...

Formal education

I have met many self-taught IT professionals I highly respect. In my own opinion, a formal degree does not automatically qualify a person for a particular job. It is more about how you educate yourself further *after* formal education. The pragmatic way of thinking and getting things done do not require a college or university degree.

However, I still believe a degree in Computer Science helps to understand all the theories involved that you would have never learned otherwise. Isn't it cool to understand how compilers work under the hood (automata theory) even if you are not required to hack the compiler in your current position? You could apply the same theory for other things too. This was just *one* example.

One year Student exchange program in OH, USA

German School Majors (Abitur), focus areas: German and Mathematics

Half-year internship as a C/C++ programmer in Sofia, Bulgaria

Graduated from University as Diplom-Inform. (FH) at the Aachen University of Applied Sciences, Germany

My diploma thesis, "Object-oriented development of a GUI based tool for event-based simulation of distributed systems," can be found at:

https://codeberg.org/snonux/vs-sim

I was one of the last students handed out an "old fashioned" German Diploma degree before the University switched to the international Bachelor and Master versions. To give you an idea: The "Diplom-Inform. (FH)" means translated "Diploma in Informatics from a University of Applied Sciences (FH: Fachhochschule)". Going after the international student credit score, it can be seen as an equivalent to a "Master in Computer Science" degree.

Colleges and Universities are costly in many countries. Come to Germany, the first college degree is for free (if you finish within a certain deadline!)
