 A robust computer system must be kept simple and stupid (KISS). The fancier the system is, the more can break. Unfortunately, most systems tend to become complex and challenging to maintain in today's world. In the early days, so I was told, engineers understood every part of the system, but nowadays, we see more of the "lasagna" stack. One layer or framework is built on top of another layer, and in the end, nobody has got a clue what's going on.

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!)
