Love this, I hope every blog have the same disclaimer about how AI is used.

If Claude gave feedback then it’s not really 100% human written is it?

I'm pretty much hardline anti-AI and even I would say this is too far. If I read documentation or ask my wife to review something, those people did not write the final product. Perhaps it would be mentioned in a citation, like this person has.

It was written on a computer with a keyboard, so clearly it's 0% human written

If you merely get feedback from a human, are they now a co-author?

Author here, happy to answer any questions. I've been working on building some higher-level abstractions on link sections (specifically, link-time optimized collections like maps (1) and sorted slices (2)) and wanted to share the hard-fought knowledge from the last couple of months.
There's a decent amount of knowledge around pre-main work in Rust, but I think this is one of the first attempts to walk through mutable link sections, which open up a pretty wide world of optimization, IMO. Even without mutability, I figured there isn't nearly enough documentation on these approaches out there.
The general lesson of these things is main is not that special and it pays to understand how your program actually starts. This has little/nothing to do with Rust or other language tools. On Linux, given a static ELF program, the kernel returns to the IP given by e_entry, which can proceed to do anything. If the program is dynamic (has a .interp) then it loads the interpreter and returns to its e_entry instead. The interpreter, in turn, can do absolutely whatever.
