Ubuntu 26.10 just replaced cp, mv and rm with Rust. For the first time, every core command on a default Ubuntu install comes from uutils, not GNU. Canonical deliberately held these three back in 26.04 LTS after a security audit found 113 issues, including race conditions in the exact tools that copy, move and delete your files. Now they ship. This episode covers why they were held back, what actually breaks in scripts, and how to switch back to GNU coreutils if you need to.

In this episode: what Ubuntu 26.10 ships, the Zellic audit and the TOCTOU races, how to check whether your system runs Rust or GNU coreutils, the rollback with coreutils-from-gnu, the behaviour differences that break scripts, the Secure Boot proposal to watch, and what it all signals for Ubuntu 28.04 LTS.

Linux 7.3 is in release candidate and heading for a launch in the second half of October 2026, and it is a likely long term support kernel, the version a large part of the computing world will run for years.

This episode covers what to expect: one of the most performance focused releases in years, with big Btrfs and EXT4 speedups and a memory fix that turns a 700 millisecond stall into a rounding error, initial Apple M3 boot support, and the very public fover AI written patches inside the kernel.

In this episode: the 7.x era, the performance wins, Apple Silicon, the AI in the kernel debate, and where the main distributions stand.

Thirty five years ago, a 21 year old student posted a message on Usenet apologizing for his little hobby operating system. That hobby now runs 90 percent of the cloud, every Android phone, all 500 top supercomputers, and rockets that land themselves. This is the story of Linux, and of why in 2026 governments across Europe are rediscovering free software for reasons that have nothing to do with nostalgia.

OpenAI says 10,000 AI agents cracked Navier-Stokes, one of the seven Millennium Prize problems, in just 88 hours. The fine print is messier: the proof covers the forced version of the problem, no independent mathematician has finished checking it, and a rival team suspects its ideas leaked through its own AI coding assistant.

In this episode: two centuries of history behind the equations, what OpenAI actually proved, the Lean formalization and its limits, the Buckmaster and Alpoge priority dispute, and what it means when machines find answers faster than humans can understand them.
