Lucas and Luna examine the Linux ecosystem as it powers everything from cloud servers to embedded devices. They trace the evolution of major distributions — Fedora's upstream-first philosophy, Debian's stability-first governance, and the commercial strategies behind Ubuntu and RHEL — without rehashing release notes. Each episode picks one layer of the stack: the container runtime that changed deployment (Docker, Podman), the systemd debate, or why Wayland still hasn't fully replaced X11 on the desktop. They also cover real-world migrations: a startup moving from CentOS to Rocky Linux, a government agency choosing OpenSUSE Leap for long-term support, and the kernel patching workflow at a FAANG-scale datacenter. Lucas brings the command-line fluency — package managers, filesystem hierarchy, SELinux contexts — while Luna asks the questions that matter to sysadmins and developers: What breaks when you upgrade? How do you audit a distro's supply chain? Can Linux ever win the desktop without
Fexingo hosts The Linux Podcast with Fexingo: Open Source Operating Systems, Distros, and Server Stack, a business show with 103 episodes published.
Episode 129 of The Linux Podcast drills into Linux's CPU frequency scaling infrastructure — specifically the intel_pstate and amd_pstate drivers. Lucas and Luna walk through how the kernel decides when to boost a core an
Lucas and Luna dive into the Linux cpuset cgroup controller, a mechanism that allows system administrators to pin specific processes to specific CPU cores and memory nodes. They explain how this differs from general CPU
In episode 127 of The Linux Podcast, Lucas and Luna explore BPF iterators — a relatively recent addition to the eBPF ecosystem that lets you traverse kernel data structures efficiently without writing manual loops in C.
In this episode, Lucas and Luna explore lockless data structures in the Linux kernel — specifically read-copy-update (RCU) and lock-free queues — and how they eliminate contention in multi-core systems. They walk through
In this episode of The Linux Podcast with Fexingo, Lucas and Luna dive into Linux auditd, the userspace component of the kernel's audit subsystem that logs security-relevant events. They unpack a real-world case: how a m
Lucas and Luna explore Linux Kernel Same-Page Merging (KSM), a memory deduplication technique that can reduce RAM usage by up to 60% in virtualized environments. They break down how KSM works, its trade-offs with CPU ove
Episode 123 of The Linux Podcast explores how eBPF (extended Berkeley Packet Filter) is transforming observability, security, and networking in Linux. Lucas and Luna dive into a specific case: how eBPF enables deep kerne
Lucas and Luna dive into Linux's dm-crypt subsystem — the kernel-level disk encryption that powers LUKS and underpins everything from laptop full-disk encryption to cloud VM storage. They break down how dm-crypt uses a d
In this episode, Lucas and Luna dive into systemd-journald, the daemon that has quietly revolutionized Linux logging. They explore how it shifts from plain-text syslog files to structured binary logs, enabling fast index
In this episode, Lucas and Luna dive into Linux Control Groups v2, the unified hierarchy that replaced cgroups v1 starting in kernel 4.5. They explain how cgroups v2 simplifies resource accounting by avoiding multiple co
Episode 119 of The Linux Podcast with Fexingo dives into overlay filesystems, the unsung hero behind Docker and container image layering. Lucas and Luna break down how overlayfs merges multiple directories into a single
Episode 118 of The Linux Podcast dives into persistent memory (PMEM) — what it is, how it differs from DRAM and SSD, and why it's reshaping storage architecture in data centers. Lucas explains the Linux kernel's direct a
In episode 117 of The Linux Podcast, Lucas and Luna dive deep into io_uring, the Linux kernel interface that's revolutionizing asynchronous I/O for storage and networking. Lucas explains how io_uring cuts system call ove
In this episode of The Linux Podcast with Fexingo, Lucas and Luna dive into Linux namespace isolation and its critical role in container security. They explore the seven key namespaces—mount, PID, net, IPC, UTS, user, an
In this episode, Lucas and Luna dive into the evolution of the Linux LIO (Linux-IO) target framework and its role in enabling NVMe-over-Fabrics in enterprise storage environments. They explore how LIO, originally built f
In this episode of The Linux Podcast, Lucas and Luna explore how combining NFS with Remote Direct Memory Access (RDMA) is rewriting the rules for high-performance storage in data centers. They break down the technical me
Episode 113 dives into Btrfs copy-on-write snapshots—a feature that makes near-instantaneous, space-efficient backups possible on Linux. Lucas breaks down how COW works under the hood, contrasting it with traditional LVM
Episode 112 of The Linux Podcast with Fexingo dives into the quiet revolution in Linux software RAID. Lucas and Luna break down how the md driver has evolved from a simple mirroring tool to a robust foundation for enterp
In this episode of The Linux Podcast, Lucas and Luna dive into the mechanics of Linux namespace isolation, the core building block of container security. They break down the six default namespaces—PID, mount, network, UT
In this episode, Lucas and Luna dive into Linux kernel live patching — the technology that lets system administrators apply critical security updates to a running kernel without a single reboot. They trace the evolution
