The notation is really not that frightening, once you get it. Just read the wikipedia article: https://en.wikipedia.org/wiki/Algebraic_notation_(chess)

Don't bother with that large table at the bottom.

The title should probably be "Is TikTok safe?" to reduce clickbait.

New comment by hkopp in "RZK: Experimental proof assistant for synthetic ∞-categories"

I think it is due to the homotopy type theory book. There is an elegant connection between category theory and type theory. I guess most of the people submitting category theory to hacker news (or any graduate math) just do it to flex and seem clever.

I have studied math and was in some lectures about category theory. I still don't get what the project is about and that fact intrigues me.

The precise mathematical definition of obfuscation and what is considered obfuscation for an average software engineer are two very different things.

In fact, the article is only about indistinguishability obfuscation. What is mostly discussed in this thread is the notion of virtual black box obfuscation (VBB). VBB has been proven to be impossible in the general case (see https://www.wisdom.weizmann.ac.il/~oded/PS/obf4.pdf). There are a few special programs where VBB is feasible, such as point functions, but in general in cannot be achieved.

Indistinguishability obfuscation (iO) means that if you obfuscate two programs that compute the same function, then you cannot distinguish them. Or put in different words, if you get two obfuscated programs, then there is no better way than random guessing (except for a factor that is negligible in some security parameter) to find out if they stem from the same original program.
