If we were to reinvent software, there are a lot of things we could do differently. A standard mime type header in all files would be amazing. Also 64-bit network addresses.

It might be surprising to some, but a file is defined by more than just the simple file extension. Good software should know for example when a file is a .jpeg even if it has a random file extension.

I googled "hello world in brainfuck" and blindly copied the AI response. Turns out it prints ":QXX[I[^XP".


Sudoku is a graph coloring problem. I wonder how good @extropic would be at other graph coloring problems, given this class of problems is NP.

Okay here's the first thing I did with THRML by @extropic It's just a basic sudoku solver. Thermodynamic computing is a bit overkill for this task but I think since humans can actually do sudoku, it's a good intuition for what's going on under the hood. With sudoku, there are…

Really curious what their response will be here. If "valid pointer + malicious offset" is something Fil-C isn't expected to protect against, then why does it try really hard to do so and only fail in this one case that the author didn't consider?

Here's a real example that truly does leak information to a user, even in Fil-C, due to a user-provided out-of-bounds offset. If your "safe C" system doesn’t protect against "valid pointer + bad offset," then it isn’t actually enforcing memory safety. gist.github.com/unixpickle/4ea…

I recently claimed in a conversation that Apple doesn't have a leg up in the AI race because no consumer cares about running models locally. Maybe what I said will turn out to be as wrong as the 1970s sentiment that no normal person would want their own computer.


I've heard differing opinions on this. If you are in SF and see someone trying to unlock a car with a wire, do you assume it's their own car, or that they are breaking into somebody else's car?
