I wrote a new post:

Building a Tiny Linux App to Explain Desktop Stutter

It is not trying to replace serious Linux tools like perf, ftrace, bpftrace, or strace.

The goal is smaller: show how to build a real little Linux app in Rust by reading /proc and /sys, parsing Pressure Stall Information, and turning kernel signals into a TUI that explains desktop stutter.

Companion source code included.

After years on Manjaro KDE, I’m testing Kubuntu 26.04 again.

This post is not “Kubuntu vs Manjaro, who wins?” It is more about how Linux desktops changed, how Ubuntu improved, where Manjaro still shines, and why hybrid NVIDIA laptops keep the decision interesting.

Built myself an ersatz-Steam Machine out of spare parts—is there some reason why Game Mode won’t let me see a game’s system requirements on its store page ?

Colorado and California age verification bills exempt open source operating systems:
https://www.gamingonlinux.com/2026/05/colorado-and-california-age-verification-bills-exempt-open-source-operating-systems/
(Good to see some win in this front, although other laws like the US federal law and the Brazilian one don't exclude FOSS so the problem still exists)
(Also, as Switched to Linux pointed out in his video, the Colorado bill is still a bit vague regarding whether restrictive copyleft licenses like GPL are excluded: https://odysee.com/@switchedtolinux:0/bill-passed-foss-carve-out-in-colorado:f)

System76 changed their stance, won't include any age attestation/verification in Pop!_OS and COSMIC:
