Add computer science and you have a programmer.
I mean, while this definitely does happen in reality, in particular if you count data scientists towards programmers, I feel like I need to point out that neither knowing computer science, nor maths, makes you a good programmer.
In fact, if you tell me someone is a computer science professor, I will assume that they are a bad programmer, because programming takes practice, which is not something they'll have time for.
For Germany, there's also https://www.gesetze-im-internet.de/index.html which lists the laws in their current version, similar to dejure, but well, the webpage is actually hosted by our government. It's as official as you're gonna get on the internet.
