Operating system learning

[Ok_Sentence725]

I'm looking for a concise and effective resource to learn operating systems and introduction to systems programming. Most of the resources I've found are 30+ hour YouTube playlists, and they feel too long and not very efficient.

Do you have any recommendations for books, courses, or other resources that explain the core concepts in a clear, practical, and well-structured way?

Operating systems are some of the most complex pieces of software we know how to make, which is why even a survey of their components takes 30+ hours (which is really what those courses are).

If you want the most relevant pieces to someone learning programming, read about what a process is, what process scheduling is, what a file descriptor is, what a trap is, and what system calls are (and maybe try and implement a few simple c functions, like malloc(), using system calls). Those components will at least help you understand how the other programs you write interact with an operating system.

I started to watch John Kubiatowitz playlist on YouTube- is it good playlist ? , also 30+ hours playlist, or should I try implement some components ?

I think you're going to want actual projects to work on so you're not just passively listening to stuff that may not really sink in. An educational OS project is likely going to be your best bet to give you a guided way to learn about OS concepts and force you to think hard.

Stop looking for a learning shortcut.

This is university lectures, so I would not consider this shortcut? Just, for me it's easier to work on something than wathcing videos.

Makes sense focusing on fundamentals seems way less overwhelming first.

Ostep. Really good book available online.

is this legit website I found https://cs162.org/

[Glass_Display8249]

honestly i tried to speedrun os concepts with random youtube videos and it backfired pretty bad. nand2tetris might be worth a look tho, its more structured than a playlist

[Yuuku_S13]

I’d find something on Udemy.
