Ultimately this kind of mechanism is what creates a society of hereditary classes.

This is not something to be celebrated - the one good thing about capitalism and open competition generally is that you can challenge this.

Ultimately this comes down VCs who fund people like this. Can we really believe the established funds look for "independent thinkers" anymore?

Clearly there is a fuzzy line of demarcation. I was thinking for a simple opt-out of any rec-sys

Yeah I meant it would avoid the necessity of age verification to solve this problem.

Age verification and how enthusiastic gov'ts are about it is concerning.

It should just be universally required to give an option to disable addictive features. Should prevent age verification, and giving users optionality is always a good thing (for them).

Can confirm that wasn't written by an LLM. To many spelling mistake

I've been using it for about 6 months. Very, very good - especially paired with anna's archive.

IT IS VERY FRAGILE! The eink screen on my first broke while in my backpack. The company is generous, I bought a new one and they gave 35% off and included all accessories (reading light, case, extra protectors). Highly recommend.

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
