My brief attempt at learning about Software Defined Radio on Ubuntu
(mendhak.com)
When my previous office building shut down, I ‘inherited’ a Pi-aware which had been set up many years ago. I was vaguely aware that it made use of something called RTL-SDR, but I didn’t actually understand what that meant. I thought it was just for tracking aircraft, but it turns out the receiver is a general purpose radio receiver and can be used for other things. The SDR simply stands for Software Defined Radio, of which there are many implementations.

Binary Distribution Rebuilds
(josefsson.org)
I rebuilt (the top-50 popcon) Debian and Ubuntu packages, on amd and arm64, and compared the results a couple of months ago. Since then the Reproduce.Debian.net effort has been launched. Unlike my small experiment, that effort is a full-scale rebuild with more architectures. Their goal is to reproduce what is published in the Debian archive.

If all goes according to plan, the Ubuntu project will soon be replacing many of the traditional GNU utilities with implementations written in Rust, such as those created by the uutils project, which we covered in February.

Carefully but Purposefully Oxidising Ubuntu

Starting with Ubuntu 25.10, my goal is to adopt some of these modern implementations as the default. My immediate goal is to make uutils’ coreutils implementation the default in Ubuntu 25.10, and subsequently in our next Long Term Support (LTS) release, Ubuntu 26.04 LTS, if the conditions are right.

An alarmingly bad official Ubuntu 24.04 bpftrace binary package

Bpftrace is a more or less official part of Ubuntu; it's even in the Ubuntu 24.04 'main' repository, as opposed to one of the less supported ones. So I'll present things in the traditional illustrated form (slightly edited for line length reasons):
