A quick life update first.

My son is now five months old and developing surprisingly quickly. Meanwhile, I continue to develop chronic sleep deprivation and persistent muscle soreness at an unreasonable rate.

Anyway.

This post is about two releases.

Fyntr is a forward proxy. It received yet another incremental update. This release includes a fix for a Too many open files issue.

KIRV, on the other hand, is something new. It's a macOS CPU throttling utility focused on process-group-level CPU control. I started developing it because Will Nolan's cputhrottle does not support Apple silicon CPUs, and I wanted something small that could cap a process like this.

cargo run --release -- <pid> <percentage>

That caps the CPU usage of the target process at the specified percentage.

Both were built primarily during fragmented late-night hours, which may explain some of the design decisions. KIRV is not a robust tool yet. It is still rough and experimental.

That's all for this update. Now, hopefully, some sleep.

A dormir.
