wtf is this stupid title

TL;DR

A company called Vers used a swarm of AI coding agents (powered by Claude) running in parallel VMs to rewrite git in Zig (“ziggit”), which enabled significant performance improvements for the Bun JavaScript runtime.

Key highlights:

• The rewrite took ~1 week and ~13 billion tokens
• ziggit achieved up to 100x speedups for some git operations vs. standard git (85x for findCommit on Apple Silicon)
• The WASM binary is 5.4x smaller than the existing wasm-git (148kb vs 806kb)
• Includes a “succinct mode” that slims down git output to save LLM tokens
• The approach used a top-level agent to orchestrate and spawn sub-agents, each working on different parts of the codebase in parallel
• Human oversight was still critical — the team regularly “checked in” to steer agents, similar to standups

The core takeaway: AI agent swarms can compress months of developer work into days, but precise prompting and human steering remain essential.

Are you using systemd or an alternative, what do you recommend?

systemd in one machine pending the switch and Artix on another (switching after the introduction of the age field to comply with the age verification law). I have been using GNU/Linux for 15 years, more than a third of that without systemd. So going back to something else felt normal and I recommend switching away from systemd

What are some significant differences to expect when switching to an alternative

Systemd is bloated so expect better performance here and there

can that affect gaming compatibility and performance?

Compatibility issues yes, but performance difference no

What last thing to consider is using the systemd forks like the unshitted one, you get the best of both worlds
