@mirsadra Ooh, the K&R bible. I loved that book. Even the introduction (from memory) „C is not a big language and it is not served well by a big book“. True. Such a good book.

Still, not sure whether everybody needs to know C today. I find it tremendously useful because if you know C you know how computers REALLY work, where many programming languages today abstract so far away from the gritty details of memory management, pointers etc that you can program without knowing how the machine works.

Nope. You know how your computer REALLY work, if you make it yourself from scratch. By designing your own chips.
