The Linux Podcast with Fexingo: Open Source Operating Systems, Distros, and Server Stack

Supply chain attacks on open source software are surging, and Linux distributions are fighting back with a tool called the software bill of materials, or SBOM. In this episode, Lucas and Luna break down how distros like Fedora and Alpine are adopting SBOMs to provide a transparent list of every dependency in a package. They discuss a real attack on the xz-utils library in 2024 that bypassed mainta...

Episode 28 of The Linux Podcast dives into Flatpak, the universal Linux app packaging format that has quietly become the default for distributing desktop applications across distros. Lucas and Luna break down why Flatpak beat Snap and AppImage, how it works under the hood with runtimes and sandboxing, and what it means for the future of Linux software distribution. They look at specific numbers: o...

For decades, the X11 display server has been the backbone of Linux graphics, but Wayland has been nipping at its heels since 2008. Lucas and Luna break down why 2025 is the year the transition finally sticks—distros like Fedora, Ubuntu, and Debian are defaulting to Wayland, NVIDIA has shipped proper drivers, and the last holdouts like screen-sharing and remote desktop are closing. They examine the...

In this episode, Lucas and Luna explore why Rust is being merged into the Linux kernel's source tree starting with Linux 6.1 — not replacing C, but coexisting for driver safety. They discuss the 2022 LPC session where Linus Torvalds approved the merge, how memory safety bugs account for roughly 65 percent of kernel CVEs, and what this means for distributions like Fedora and Debian that will ship t...

In this episode, Lucas and Luna dig into the milestone that Linux enthusiasts have been watching for decades: the Linux desktop market share finally crossing 5 percent globally in early 2026. They break down the specific drivers behind the number — Steam Deck's Linux-based SteamOS pushing gaming adoption, the rise of immutable distros like Fedora Silverblue and Vanilla OS making Linux more reliabl...

Episode 24 of The Linux Podcast with Fexingo dives into systemd — the init system that sparked the most divisive debate in Linux history.

Episode 22 of The Linux Podcast explores how kernel live patching is transforming server maintenance. Lucas and Luna discuss the origins of the technology with Ksplice at MIT, its adoption by major distros like Ubuntu's Canonical Livepatch and SUSE's kernel live patching, and the real-world impact on uptime and security. They walk through how live patching works under the hood — using ftrace and s...

Lucas and Luna break down how Linux gaming has quietly surpassed Windows on raw frame-rate performance in 2026. They dig into Valve's Proton 9.0, the shift to Vulkan as a universal API, and why NVIDIA's open-source driver gamble changed the game. Specific benchmarks from Phoronix and the Steam Hardware Survey show Linux now delivers 5–10% better fps on the same hardware for modern titles. The host...

In this episode of The Linux Podcast with Fexingo, Lucas and Luna explore why Linux laptops have become a viable choice for everyday users in 2026.

The hosts compare the experience to pre-installed Windows laptop...

In this episode, Lucas and Luna explore the rise of immutable Linux distributions and why they represent a fundamental shift in how we think about system administration, security, and package management. With Fedora Silverblue, openSUSE MicroOS, and Vanilla OS leading the charge, they break down what immutability actually means under the hood, how atomic updates eliminate dependency drift, and why...

In this episode, Lucas and Luna explore why Python remains the most powerful entry point for new Linux users, even in 2026. They trace the language's role from simple scripting to powering AI and machine learning workflows on Linux, using specific numbers like the 8 million Python developers on GitHub and the 60% of Linux packages that depend on Python. They discuss how distros like Ubuntu ship Py...

Episode 17 of The Linux Podcast: OpenZFS is not just a file system—it's a storage management paradigm that lets sysadmins do things no traditional Linux file system can. Lucas and Luna dive into OpenZFS's arcane but powerful features: copy-on-write snapshots that take seconds regardless of volume size, built-in RAID-Z that eliminates the need for hardware RAID, and instant incremental replication...

Lucas and Luna explore the quiet rise of immutable Linux distributions—systems where the root filesystem is read-only and updates are atomic. They dig into why Fedora Silverblue, openSUSE MicroOS, and Vanilla OS are gaining traction beyond just developers and into mainstream desktop use. Lucas explains how immutable distros solve the 'dependency hell' and broken-update problems that have plagued L...

Lucas and Luna explore how Fedora, Red Hat's upstream distribution, has become the primary driver of Linux innovation. With a 13-month lifecycle, Fedora serves as the testing ground for technologies like Wayland, PipeWire, and early kernel features before they land in enterprise RHEL. The episode examines Fedora's release cadence, its role in the GNOME ecosystem, and why it's the preferred distro...

Episode 14 of The Linux Podcast with Fexingo dives into the quiet revolution in Linux memory management: Zram. Lucas explains how Zram creates a compressed block device in RAM, swapping pages before they hit disk, and why it dramatically outperforms traditional swap on SSDs for most desktop and server workloads. Luna brings up real-world benchmarks from Phoronix showing up to 40% better responsive...

Long-term support kernels power everything from hospital MRI machines to stock exchange servers — but how did a voluntary maintenance model become the default for multi-billion-dollar industries? Lucas and Luna trace the history of LTS from Greg Kroah-Hartman's 2011 initiative to today's six-year support windows, explain the difference between kernel LTS and distro LTS, and look ahead to the Rust-...

Episode 12 of The Linux Podcast dives into the biggest change to kernel development in decades: the gradual integration of Rust as a second language alongside C. Lucas and Luna trace the story from the 2022 initial merge of Rust support to the May 2026 milestone where over 200 contributors have submitted Rust patches for drivers and subsystems. They discuss the specific memory-safety wins—like eli...

Linux's kernel configuration has been a dark art for decades, but a new wave of distros like CachyOS and Nobara are shipping custom-tuned kernels out of the box. Lucas and Luna dig into why the one-size-fits-all kernel from mainline distributions is losing ground, how CPU scheduler patches like BORE and CacULE are boosting desktop responsiveness, and what this means for everyone from gamers to ser...

Lucas and Luna dive into ZFS on Linux—why it’s gaining traction for data integrity, its 2026 native integration into Ubuntu, and how it compares to Btrfs and ext4. They explore real-world use cases at Netflix and Backblaze, the licensing friction with the Linux kernel, and whether ZFS will ever become the default filesystem. A specific, numbers-rich conversation for anyone running homelabs or ente...

Featuring specific benchmarks on sandboxing overhead and real-world compatibility from the lates...

For over a decade, the future of Linux graphics has been dominated by one question: when will Wayland replace X11? In this episode, Lucas and Luna unpack the technical and political reasons why Wayland has finally become the default display protocol for most major distributions in 2026. They trace the history from X11's origins in 1984 to the GNOME and KDE transitions, explain key features like pe...

Lucas and Luna dive into Btrfs, the copy-on-write filesystem that's quietly replacing ext4 across major Linux distributions. They unpack why Fedora and openSUSE defaulted to Btrfs years ago, how features like snapshots, compression, and RAID-like capabilities make it a fit for everything from single laptops to multi-disk servers, and where it still stumbles — like the RAID 5/6 code path that remai...
