We kick off the show with an important community feedback segment addressing a "Puzzled Parent" who wants to keep their kids safe online using open-source tools. The team breaks down excellent FOSS solutions for the Linux desktop, router-level blocking (like Pi-hole and NextDNS), and open-source mobile tools for /e/OS like NetGuard and TimeLimit.

Next, Ryan takes us on his personal journey from Server Purgatory to Paradise. He walks through setting up a low-power, budget-friendly HP Prodesk mini-server from eBay, detailing his troubleshooting nightmare with an unbaked Ubuntu install, his redemption using Fedora, and how he deployed a modern stack using Podman, Cockpit, Tailscale, and Filebrowser.

In hardware news, Jill delivers some bittersweet "end of an era" updates as the classic AMD K5 processor family and the Intel 486 are officially deprecated and removed from the upcoming Linux Kernel. We discuss why 30-year-old museum-grade hardware is being phased out due to maintenance burdens and share the best retro-distributions to keep your vintage rigs alive.

Finally, Zeb brings us up to speed on the "Dirty Frag" local privilege escalation vulnerability and how the latest Linux kernel stable releases fully mitigate it. We wrap up the show by celebrating the 30th birthday of Tux the Penguin, sharing the hilarious origin story of how a zoo animal bite in 1993 led to Larry Ewing designing the ultimate mascot in GIMP.

Next, Mo provides an expert breakdown of how AI is revolutionizing security research. From Project Glasswing to the Alpha Omega project, we look at how frontier models are being used to find (and fix) vulnerabilities in critical infrastructure like the Linux kernel. We discuss the "personality quirks" of different AI models and why human expertise is still the "apex predator" in the security chain.

Ryan also shares an update on his "GIMP Challenge," revealing how he’s successfully moved his professional thumbnail workflow to open source. This leads to a deep dive into Adobe’s recent "bad behavior," including $150 million settlements and secret modifications to system hosts files. We ask the tough question: When does commercial software become malware?

Plus, we cover the latest news, including Linux 7.0-rc7, Firefox’s new free VPN, and Zorin OS’s firm stance against mandatory age verification laws.
