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.

Hi Everyone! 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 / window usage

- compilable on Mac, probably also Linux, can cross-compile for esp32 there

- wrote for fun / cyberdeck project

Sample output from esp32:

    xcc700.elf xcc700.c -o /d/cc.elf
    
    [ xcc700 ] BUILD COMPLETED > OK
