SUDO Show 76, “ABCs of CVEs,” breaks down how modern Linux vulnerabilities go from scary headlines to real-world fixes. Bill, Neal, and Brandon start with conferences and Neal’s new Framework 13 Pro running Fedora, then dive into AI‑assisted security research and what tools like Claude and others are actually doing in the CVE pipeline. Neal walks through recent high‑profile issues like Pack2TheRoot in PackageKit, the copy.fail kernel optimization bug, and the Dirty Frag vulnerability, explaining how disclosure, embargoes, and coordination really work from a distro maintainer’s perspective. Brandon then focuses on CVE patching best practices, testing and release strategies, tools like Foreman and Uyuni for managing updates, and how to interpret CVSS scores and risk without panicking, before the crew wraps with advice for new grads who want to get into security without setting their hair—or their clusters—on fire.

SUDO Show 75, “I Don’t Know How to Make Coffee,” is a full‑on April Fools special where “business meets Linux” takes a back seat to pranks, retro war stories, and questionable life choices. Bill, Neal, and Noel start with open source airplanes, HDMI‑to‑floppy adapters, and whether airplane wings actually flap, then quickly descend into cargo‑class containers, VM‑matrix jokes, and vintage Linux desktop pain with FVWM95 and XFree86. From decaf‑only coffee stunts, BashRC logout traps, PC speaker torture, and ping‑flooded LAN parties to PACMAN.BAT in the school lab, Gentoo use‑flag accidents, OpenStack root‑password “oops” moments, and a threat to invent Fedora.js, they share their most devious tech and non‑tech pranks. Along the way, they talk MSP coffee culture, two‑pots‑a‑day network engineering, Kubernetes as “all YAML,” and close by reminding you not to try any of this at work—no matter how good that April Fools itch feels.

Moving to the cloud was easy; getting out is the hard part. In SUDO Show 74, Bill, Neal, and Noel dig into “The Great Cloud Breakup” and why more teams are rethinking cloud‑first dogma as exit fees rise and data residency laws go live across the US, EU, UK, and beyond. They talk through how modern Linux, NVMe‑over‑Fabrics, and on‑prem hardware make repatriation realistic again, spotlight rclone and Nick Craig‑Wood for making data movement sane, and share hard‑won stories about ugly data transfers and hybrid architectures. The episode wraps with a tongue‑in‑cheek “repatriate AWS onto three Raspberry Pis” action item and a NetHogs quick fix you can run today to catch chatty services before egress fees blow up your budget.
