Rough draft for comment - passes core cpython 3.12 tests with an inspired design.

Does it isolate keys away from bots?

Already done, months ago, with better taste: https://github.com/rustcoreutils/posixutils-rs

I needed this for experimenting. Sharing with others. Please file issues, to extend.

The next iteration of awk?

Passes 100% of userland tests, supporting 99% of linux syscalls (though very few filesystems!)

Early boot and early page table setup, logging single characters to simulated serial console.

Then keep adding tests/features/tests/features/...

I always wanted a kernel where I can experiment with the device driver model, eBPF, device tree and more. Now I've built one:

Somewhat related, a kernel in Rust: https://github.com/jgarzik/hk

Accelerated by Claude Code, leashed tightly by unit and integration tests, and test-driven development.

Speaking as a compiler and kernel expert, the productivity boost for domain experts is real.

Compiler status: Full C99 compliance, test suites pass, alpha-beta stage, starting to test on Gentoo and open source package builds "real world builds"

Posixutils status: Very close to 1.0 (all POSIX utils, all POSIX util features, tests pass)

Love this! I had the same idea, and was pondering funding apps like this. Was going to call it "SimpleFree" and focus on privacy, offline, mobile, games.

Thanks! There is very little info available on useful, working Veo 3 techniques, so I cobbled together what I could find, with my own experiments: https://x.com/jgarzik/status/1926496820311605577

No, not using sqlite under the hood.

This is using Rust's native sqlparser crate, which is quite powerful, plus an internal memory database.

We can extend this beyond what sqlite SQL supports.

posixutils is far, far more utils than coreutils. posixutils includes awk, m4, a C compiler, etc.

At the same time, as you note, this does not include GNU extensions inside each utils.

The posixutils-rs project just merged a full, POSIX compliant shell.

It is hoped that posixutil's awk's bytecode-based modern design should keep performance high, theoretically higher than ancient C-based awks.

Inspired by Ray Gardner's "wak" awk implementation https://github.com/raygard/wak

A volunteer benchmarking our awk on a 1-billion line text file would be welcome.
