First up in the lobby, we bring in a special VIP segment featuring Mo and guest Jeff Ligon from Red Hat to dive deep into Linux in the automotive space. How does a car's kernel differ from your laptop, and how does open source handle strict real-time safety regulations?

Next, a Grandmaster-level milestone: DistroWatch just turned 25! We look back at the history of distro-hopping, the days of ordering physical Linux CDs in the mail, and how the ecosystem has evolved into modern immutable architectures.

Then, Zeb calls out an enemy Ultimate in the news. The Arch User Repository (AUR) has faced consecutive malware attacks, and we break down what you need to know to stay safe. Plus, we highlight the brand-new features of the Linux 7.1 kernel release!

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.
