phonecam: Android phone as a webcam over USB (Linux)

A systemd user service that waits for an Android phone to be plugged in over USB, then uses scrcpy to stream the phone's camera into a v4l2loopback device (/dev/video0). Any app (Meet, Zoom, OBS, browser) then sees it as a normal webcam. Unplug the phone and the service goes back to waiting; plug it in again and the camera comes back on its own.

laya-rs vs jev vs gliner-rs vs semif-rs (Qwen3.5-4B) vs Intern-Decision-4B vs Julia-1 — typed-decisions comparison

Repos: laya-rs, semif-rs, gliner-rs

Not the stock distributions but Rust ports running on CUDA. Laya-rs and gliner-rs are a bit faster than Python official distribution, Semif-rs is 25% slower than llama.cpp so it has space for improvements.

Ran the same jev-questions fixture (3 workflows: resume screening, support-session evaluation, guardrail moderation) through:

• laya-rs — Rust reimplementation of Laya (laya-typed-decisions checkpoint, ModernBERT-large

Installing Arch Linux on Lenovo Yoga Slim 7 14AKP10

After spending 24 hours across planes and airports I got back home and spent the rest of my weekend trying to get this beautiful laptop to work.

Here are the fixes so you don't have to suffer.

General

Install Arch Linux as usual.

What is covariance?

Covariance describes how lifetimes behave in type substitution. A type is covariant over a lifetime if it can accept shorter lifetimes than originally specified.

📌 Example:

let short: &'short i32 = &5;
let long: &'long i32 = short; // allowed if &'long is covariant over 'short
