Isn't that rdtscp ( https://www.felixcloutier.com/x86/rdtscp )?

Fun read! I built a minimal Linux shell [0] in c and Zig last year which does not depend on libc. It was a great way to learn about execve, the new-ish clone3 syscall and how Linux starts a process. Parsing strings is the least fun part of the building the shell.

Recurse center is awesome! The community is curious, kind and supportive. I did 2 batches there and each one expanded my horizons as a programmer.

I've been building small programs in Zig, C and ARM64 assembly without relying on libc and only using Linux syscalls directly.

Some examples:

- A minimal C shell with built-ins like cd, pwd, type: https://gist.github.com/rrampage/5046b60ca2d040bcffb49ee38e8...

- Terminal Snake game which fits in a QR code using Linux syscalls for drawing: https://gist.github.com/rrampage/2a781662645dc2fcba45784eb58...

- HTTP server with sendfile support in ARM64 assembly: https://gist.github.com/rrampage/d31e75647a77badb3586ebae1e4...

I learned to handcraft a static ELF binary using just GNU assembler (no linker): https://gist.github.com/rrampage/74586d0a0a451f43b546b169d46... . Trying to see if I can craft a small assembler in ARM64

Kudos! Especially for the asm.

http.S is something I wanted to do by myself, ended up with generating data in asm and reusing Go for a http server.

Yurichev's SAT/SMT by Example [0] is a great (free!) resource for learning how to model problems to SAT/SMT

I second this as a good starting point. When I was picking up z3, this was helpful.

Storage cost is much higher. Express One Zone is $0.16 per GB while standard S3 is $0.023 per GB ( https://aws.amazon.com/s3/pricing/?nc=sn&loc=4 )
