It's weird how even pure languages tend to treat the Unix execution model as ambient state. Are there any PLs that define a main function like this? fn main(args, stdin, stdout, env) -> exit code

Computing AMD-specific instructions on Intel by just brute-forcing the whole execution space and seeing which values differ:

Took me a while to figure out how to debug a hanging Rust test. The best invocation seems to be: $ RUST_TEST_THREADS=1 cargo test -- --nocapture This will print test names before execution, so you can see where you're hanging. --nocapture lets you see print output immediately.
