This is a list of resources I found useful. I am not an expert in all of these topics but all the resources listed here made an impact on me. I've 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 strongly believe that educating yourself further is one of the most important things you should do in order 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 favorite search engine when you are interested in one of the resources...

Technical books

Technical bibles

I didn't read them from the beginning to the end, but I am using them to look up things.

Self-development and soft-skills books

Technical video lectures and courses

Some of these were in-person with exams, others were online learning lectures only.

Fiction and more books

Many fiction and non-fiction books I read are not listed here. This site mostly includes resources which made an impact on me regarding the work I do only and not on my personal life. Do you recommend a good Science Fiction Novel? E-Mail me; I can also provide my own recommendations! :-)

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 certain 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 achieve a good understanding of all the theory involved which you would have never learned about otherwise. Isn't it cool to understand how compiler work under the hood (automata theory) even if in your current position you are not required to hack the compiler? You could apply the same theory for other things too. This was just *one* example.

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

I was one of the last students to whom was 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 literally translated "Diploma in Informatics from a University of Applied Sciences (FH: Fachhochschule)". Going after the international student credit score it is settled between a Bachelor of Computer Science and a Master of Computer Science degree.

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