Codeberg.org is really great.

Also I recommend self-hosting Gitea for private projects and backing-up public projects

True it is pretty dated. OP was requesting resources that cover *all* of physics and Landau popped into mind. Is there a modern series of textbooks that offers such a broad coverage?

Road to Reality is good to get a general overview of *everything* but I dont think you can actually learn the things he talks about. For example, the jump from calculus in R^2 to Riemannian surfaces is insane and leaves a ton out

Freshman university textbooks have what you need. Two of the most popular are:

- University Physics by Young and Freedman

- Fundamentals of Physics by Halliday, Resnick, Walker

- Modern Physics by Krane

You might guess that real physics is not actually in freshman textbooks, and you are right. Modern physics requires rigorous mathematics.

For a nonrigorous introduction/overview:

- The Road to Reality by Roger Penrose

If you want to actually learn almost all of physics at a high level:

- Course of Theoretical Physics by Landau

Note that Landau is extremely difficult.

If you want to learn the math needed for modern physics (topology) in the context of physics, nonrigorously:

- Geometry, Topology, and Physics by Nakahara
