PHP2Shell hit on October 21 with two critical 9.2-rated flaws, CVE-2026-109618 and CVE-2026-109619, now patched, while a third issue, CVE-2026-115560, remains unpatched with only a mitigation. This guide explains what each flaw breaks, then walks through patching and verifying PHP on Ubuntu, Fedora, and CachyOS so you know the fix is live.
Flathub nears five billion downloads on a design most users never see: shared runtimes. This hands-on guide, beginner through advanced, explains what a runtime is, why it ends dependency hell, how /app and /usr combine inside the sandbox, and what OSTree deduplication does on disk, tested on Ubuntu, Fedora, and CachyOS.
A complete calibre walkthrough for Linux: install it on Ubuntu, Fedora, and Arch with live terminal output, organize a library with tags, series, and virtual libraries, pick the right format from EPUB to KEPUB, convert from the GUI or ebook-convert, sync to Kindle and Kobo, and serve books to your phone. Beginner to intermediate.
Eight eMudhra CA intermediates shipped private keys so weak anyone can rebuild them. This guide runs three read-only checks - probe, grep, package version - on Ubuntu, Fedora, Rocky, and CachyOS, then shows the right ca-certificates patch order, the per-distro fix table, and the container, Go, and IoT stores a package manager never sees.
A concept explainer on why Linux apps lean on shared libraries instead of shipping their own copies. I cover package managers, the dynamic linker, and the SONAME machinery behind every app launch, then build a missing-library demo with libmylib and repair it identically on Ubuntu 26.04, Fedora 44, and CachyOS. Beginner to intermediate.
A live USB boots Linux from a flash drive and saves nothing. This guide covers the three moving parts: the read-only SquashFS root, the RAM-backed copy-on-write overlay, and the boot path that joins them, then compares the Ubuntu, Fedora, and CachyOS live stacks, busts the loads-into-RAM myth, and answers five common questions.
I connect three AI moments from the Linux 7.3 window into one analysis: the disclosed Claw driver, Linus's tagged LLM branch, and the live debate over the Assisted-by trailer. Built from primary patches and live 7.3 kernel captures, this piece is for anyone arguing about what AI's role in kernel development should be.
Valve's latest beta made the Steam client on Linux 64-bit for the first time and moved it inside a pressure-vessel container called steamrt3c. This hands-on guide covers what changed, what did not, how to opt in, the distro requirements, the quirks worth knowing, and why 32-bit multilib support is still required.
A post-release review of Linux 7.3 for people who want facts, not predictions: what landed in the October 18 tag, the upstream numbers behind the faster-I/O headline, Steam Controller and MSI Claw kernel support, and which distros have already shipped it. For desktop and handheld Linux users on Gen5 NVMe hardware.
GNOME finally shipped something non-developers can actually download, but only if you can accept an OS that might need reinstalling. GNOME OS Preview is upstream's own image-based system, built from the stable GNOME stack. I booted the live ISO to verify what it delivers today: the real integrations, the rough edges, and one memory-management surprise.
