Hi HN,I built a small Linux CLI tool called witr (Why Is This Running?).The idea came from a situation most of us have hit: you log into a machine, see a process or port running, and immediately wonder why it exists, who started it, and what is keeping it alive right now.witr traces a process, service, or port back to its origin and responsibility chain and explains it in a way that’s quick to read, especially when you’re debugging under pressure.This is v0.1.0. It’s intentionally small and focused.
Feedback, criticism, and edge cases are very welcome.Repo: <a href="https:&#x2F;&#x2F;github.com&#x2F;pranshuparmar&#x2F;witr" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;pranshuparmar&#x2F;witr</a>

I just wrote my first compiler!- single pass, recursive descent, direct emission- generates REL ELF binaries, runnable using ESP-IDF elf_loader- very basic features only, just enough for self-hosting- treats the Xtensa CPU as a stack machine for simplicity, no register allocation &#x2F; window usage- compilable on Mac, probably also Linux, can cross-compile for esp32 there- wrote for fun &#x2F; cyberdeck projectSample output from esp32:<pre><code> xcc700.elf xcc700.c -o &#x2F;d&#x2F;cc.elf
 
 [ xcc700 ] BUILD COMPLETED &gt; OK
 &gt; IN : 700 Lines &#x2F; 7977 Tokens
 &gt; SYM : 69 Funcs &#x2F; 91 Globals

</code></pre>
My best hope is that some fork might grow into a unique nice language tailored to the esp32 platform. I think it is underrated in userland hobby projects.
