We also welcome Red Hat VP Mike McGrath for an in‑depth conversation about Lightwell - a new approach to simplifying modern infrastructure, improving predictability, and supporting open source ecosystems at scale. Mike shares insights on AI’s rapid rise, open source economics, partnerships with industry heavyweights, and how Lightwell helps developers, sysadmins, and researchers in real‑world environments.

Along the way, we cover Session chat updates, website security improvements, and reflect on the origins of Destination Linux with Rocco. We wrap with a fun lightning round.

We explore the realities of surveillance, motion‑sensing routers with privacy tradeoffs, and Craig’s full breakdown of the chaos and hype coming out of Black Hat - including agentic AI, guardrails that don’t guard anything, and the growing divide between restricted AI and open‑weight models. Craig also covers the Cold Incident Response Conference, AI‑powered threat detection, and a Bitcoin RNG hack that proves why dice still matter.

Jill celebrates Linux’s 35th birthday and Valve’s 30th anniversary with a look back at the milestones that shaped open source, gaming, and the Linux desktop.
