Some books I learnt off and still seem to be around

Modern Operating Systems by Tanenbaum is a good theory book - this will probably answer your questions about flushing etc

for down and dirty:

Advanced Programming in the UNIX Environment

TCP/IP Illustrated, Volume 1 (2 and 3)

Yeah it's basically an Operating Systems book like Tanenbaum's "Modern Operating Systems".

You just caught me at a moment where I'm reading Tanenbaum's book on Modern Operating Systems. Tanenbaum simplifies a lot of things, but here is his contribution [1]:

> The second development concerned the language in which UNIX was written. By now it was becoming painfully obvious that having to rewrite the entire system for each new machine was no fun at all [0], so Thompson decided to rewrite UNIX in a high-level language of his own design, called B. B was a simplified form of BCPL (which itself was a simplified form of CPL, which, like PL/I, never worked). Due to weaknesses in B, primarily lack of structures, this attempt was not successful. Ritchie then designed a successor to B, (naturally) called C, and wrote an excellent compiler for it. Working together, Thompson and Ritchie rewrote UNIX in C. C was the right language at the right time and has dominated system programming ever since.

Tanenbaum doesn't say it, but it almost seems like B and C were designed for creating UNIX. I wonder to what extent the authors of B and C were designing the languages for creating UNIX.

[0] In one of the previous paragraphs, Tanenbaum mentioned that the first version of UNIX was written in assembly.

While the tone of the parent is a bit, well, it could be better :) I do think the parent has a point. For example, I just finished reading Modern Operating Systems by Tanenbaum. His experience shows. This form of experience cannot be showcased by someone who's learning or just has learned a particular technology. And I know I'm taking one of the giants as an example, and they show this particular example in its most extreme form.

With that said, I have read/watched tutorials by people who just learned something and the empathy level to beginners is really high. That's something that can be missing with people who have years and years of experience.

Another interesting rabbit hole to explore is the compiler. Back in the day I wrote a toy compiler for a college course and used this text book: "Compilers: Principles, Techniques, and Tools". a.ka. "The Dragon book", but I would look at some of the other books here like "Modern Operating Systems" before this.
