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

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 OEM deals? No fanboy evangelism, no terminal-porn demos. Listeners come for the technical depth — kernel config options, Wayland protocols, cgroups v2 — but stay for the operational judgment: which distro for a Kubernetes node, which init system for an embedded device. What does it take to run Linux at scale without burning out your ops team? #Linux #OpenSource #Technology #FexingoBusiness #BusinessPodcast #Distro #Kernel #Containerization #Docker #Podman #Systemd #Wayland #RHEL #Ubuntu #Fedora #Debian #Sysadmin #DevOps Keep every episode free: buymeacoffee.com/fexingo© 2026 Fexingo.

  • How Linux BPF Is Supercharging Network Performance

    How Linux BPF Is Supercharging Network Performance
    Jun 29 2026
    Episode 80 of The Linux Podcast dives into how eBPF is revolutionizing network performance beyond just replacing kernel modules. Lucas and Luna explore a specific case: Cloudflare using eBPF to handle DDoS mitigation at line rate, processing millions of packets per second without touching userspace. They break down the BPF virtual machine, its verifier safety guarantees, and why companies like Netflix and Meta are now running eBPF in production to shave microseconds off latency. The episode also touches on the emerging bpfilter project as a potential iptables replacement. If you've heard eBPF buzz but never understood the concrete wins, this episode gives you the numbers and the architecture. #eBPF #BPF #Cloudflare #Netflix #Meta #LinuxKernel #NetworkPerformance #DDOS #bpfilter #iptables #VirtualMachine #Verifier #Latency #Technology #LinuxPodcast #FexingoBusiness #BusinessPodcast #OpenSource Keep every episode free: buymeacoffee.com/fexingo

  • How Linux Fanotify Is Revolutionizing File Change Monitoring

    How Linux Fanotify Is Revolutionizing File Change Monitoring
    Jun 28 2026
    In this episode, Lucas and Luna explore Fanotify, the Linux kernel's file change notification system that is replacing tools like inotify for modern workloads. They break down how Fanotify monitors entire filesystems at once instead of individual files, making it ideal for antivirus scanners, backup tools, real-time replication, and systemd-journald. Lucas explains the key difference from inotify—no per-watch memory and no path walking—using a concrete example of monitoring a container's overlay filesystem. Luna brings up the practical costs: Fanotify requires root privileges, and it can still flood user-space with events if not throttled. The episode also covers the fanotify manpage, fanotify_mark() system call, and how features like FAN_OPEN_PERM enable policy-based access decisions. They wrap with a look at the future: the FAN_RENAME flag in Linux 6.0 and how Fanotify handles mount namespaces for containers. Perfect for anyone building infrastructure that needs near-real-time filesystem awareness. #Fanotify #Linux #FileChangeMonitoring #Inotify #Kernel #Filesystem #SystemAdministration #DevOps #ContainerSecurity #Antivirus #BackupTools #RealTimeReplication #Systemd #Linux6.0 #OpenSource #Technology #FexingoBusiness #BusinessPodcast Keep every episode free: buymeacoffee.com/fexingo

  • Why the Linux Kernel Is Now Written in Rust

    Why the Linux Kernel Is Now Written in Rust
    Jun 28 2026
    Episode 78 dives into the biggest programming language shift in Linux history: Rust code inside the kernel. Lucas explains why the C language's memory-safety bugs have caused decades of security patches, and how Rust's compile-time guarantees eliminate entire classes of vulnerabilities at the source. He walks through the key milestones: the 2022 merge of initial Rust support, the first Rust network driver in 2024, and the current state as of mid-2026 where over 2.5 million lines of Rust now ship in mainline Linux. Luna asks about the learning curve for kernel maintainers and whether Rust will ever fully replace C. The hosts discuss the biggest real-world payoff so far—a filesystem module with zero reported memory bugs in production—and what's next for Rust in subsystems like scheduling and memory management. If you've wondered whether Linux is quietly undergoing a generational rewrite, this episode gives you the concrete numbers and the human story behind the transition. #Linux #Rust #Kernel #MemorySafety #CLanguage #OpenSource #LinuxKernel #Programming #SystemsProgramming #SoftwareEngineering #Security #Technology #FexingoBusiness #BusinessPodcast #Podcast #LinusTorvalds #RustForLinux #MiguelOjeda Keep every episode free: buymeacoffee.com/fexingo
