76: ABCs of CVEs | SUDO Show 76 14.05.2026 51min

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.

75: I Don’t Know How to Make Coffee | SUDO Show 75 01.04.2026 1h 7min

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.

74: The Great Cloud Breakup | SUDO Show 74 26.02.2026 1h 20min

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.

68: Quarterly Watercooler 18.06.2024 1h 5min

Video: https://youtu.be/Tu_AJ2Zjf7A Bill, along with Neil and Brandon, dives into the world of Atomic desktops within the Fedora community on their podcast, The Sudo Show. They introduce the concept of “water cooler episodes” where they explore a range of intriguing topics in the open-source community. Each of the Atomic desktop variants, such as Silverblue, Kinoite, Sericea, and Onyx, is overseen by specialized interest groups within Fedora. The team engages in a lively debate about the naming conventions for these variants and delves into the crucial principles of ensuring reliable updates and system safety within the Atomic desktop framework. The hosts tackle the challenges associated with managing packages between RPM OS tree and flat packs, emphasizing the significance of server-side composition for scaling deployments effectively. They also discuss the potential of introducing Atomic spins in various desktop environments, like the XFCE-based VoxSight prototype. Brandon provides insights on utilizing container files for distribution ease, while Neil elaborates on the core tenet of server-side composition in RPM OS tree technology. The conversation smoothly transitions into exploring the practical application of Atomic desktops in fleet management scenarios, highlighting their suitability for low-customization and low-maintenance workloads similar to Chromebooks. The hosts offer contrasting viewpoints on user experiences for developers and basic computing needs, deliberating on the feasibility of Atomic spins based on individual use cases. They speculate on the broader adoption of Atomic spins across different Linux distributions, pondering whether this server-centric approach could potentially become a standard in the open-source realm or remain restricted to specific enterprise-oriented distributions. Reflecting on the future potential of Atomic desktops beyond Fedora, the hosts consider their adaptability in other Linux ecosystems such as Debian and Arch-based distributions. They ponder whether this innovative distribution delivery approach will witness widespread acceptance or retain its niche status in the Linux domain. The insightful discussion sheds light on the intricacies of integrating Atomic spins into existing distribution landscapes, offering valuable perspectives on the future of immutable desktops in the open-source sphere. In a separate segment, Neal and the group explore varying approaches to atomic updates within different Linux distributions. They touch upon Ubuntu’s use of snaps for composing dependency groups, OpenSUSE redirecting transactions to an offline target through BTRFS subvolumes, and atomic updates in Arch-based Steam OS. The conversation shifts towards discussing the evolving relationship between Nouveau and NVIDIA, with the open-source driver incorporating firmware for enhanced performance akin to AMD GPUs. The group delves into topics like Vulkan compilers, the promise of improved reliability, and the implications for CUDA applications. 00:00:13 Welcome to The Sudo Show 00:02:19 Around the Water Cooler 00:27:13 NVIDIA Nouveau Updates 00:40:21 Linux Graphics Driver Components 00:46:55 Advancements in OpenCL Implementations 00:49:48 Exciting Features of KDE Plasma 6 00:51:49 Integration of SDDM in KDE 00:56:51 Challenges with KDE’s PIM Suite 00:59:40 Issues with CalDAV Implementations 01:02:32 Revitalization of KDE’s PIM Stack 01:04:51 Returning to Work at the End
