  Pair this with Fil-C(https://fil-c.org/) and now you have C but as a truly bonafide scripting language.

  Really cool idea.

  I was wondering why the release explicitly is `cjit-x86_64-ubuntu-24.04` instead of generic linux, but it does in fact appear to not work on Arch:

  `tcc: error: file '/lib/x86_64-linux-gnu/libgcc_s.so.1' not found`

  I'm guessing that's due to a `dlopen` since it's not listed by `ldd`

  The site visually feels "compressed" due to the font used? It's a bit jarring. The tutorial link in the header nav doesn't go anywhere.

  Looks interesting and fun, but in no instance of any C compiler I've come across is the "classic example" of "hello, world" using `fprintf(stderr, ...)`

  To each their own I guess.

    Give io buffering an inch and it will take a mile

  Did you use Codex 5.4 for the web design? :p I think Codex tends to do very similar designs, could be completely mistaken tho

    The source for the site is here: https://github.com/dyne/cjit/tree/main/docs. It's a VitePress site with a custom theme. Glancing through the code, I don't see any obvious signs of LLM coding. It also definitely wasn't created with Codex specifically, because according to the commit history, the first version of the site was in late 2024, months before Codex even released.

    Looks like a generic static site generator page to me. I'd be surprised if dyne folks used a closed system like Codex specifically.

  Definitely was not expecting this reference.
