So the standard I/O streams in C (stdin/stdout/stderr) are unoriented by default until first use (ie. calling fgetc vs fgetwc on stdin determines if it is a byte-oriented stream or wide-oriented stream).
However, POSIX forbids `perror` from changing the orientation of unoriented streams,

@piccalil.li Are article heading links broken on the site right now? I see markup indicating support in the HTML so the CSS might be borked

The `ps` command from procps-ng has so many options, all in different styles, all that may or may not clash with one another it's kinda funny.
For example, you can't get the same output as `ps j` (without using BSD syntax) without multiple commands.

Looked at Teal today (github.com/teal-languag...) to see if it works nicely with my use-case on my website, but unfortunately its union type is lacking and literal types are currently unsupported.
Looking at Luau now (luau.org) and it seems promising

I was curious about how the various tools for scripting eBPF work re: running the script and creating the eBPF bytecode, so I did a little digging:
