Omarchy is launching official Mac support for Apple Silicon through a dedicated team called Omarchy M. The team of 15 developers is building a native installer, GPU drivers, and hardware support to run Omarchy on M1, M2, and newer Mac machines alongside macOS, with the first release targeting full compatibility for M1 and M2 variants.
Salmon is a Linux monitoring utility that tracks systemd service health and custom checks via periodic commands, displaying alerts through a tray icon and desktop notifications. The project consists of a Go background service (salmon) that monitors local or remote machines and a Rust desktop client (salmon-watch) that connects to multiple instances and displays incidents.
Omarchy v4.0.4 releases a custom Linux kernel optimized for desktop responsiveness, gaming compatibility, and hardware reliability. The update improves Btrfs performance, power management, and fixes audio, touchpad, display, and startup issues across various systems.
A Swift-based external builder tool for Nix on Darwin that enables building Linux packages on macOS without a remote VM, reproducing Determinate Nix's native-linux-builder functionality for upstream Nix installations with optional Nix-darwin module integration.
Thurbox is a tmux-based TUI and CLI tool that orchestrates multiple coding agents (Claude Code, Codex, Aider, etc.) in parallel sessions within a single terminal. Each agent runs in its own persistent tmux session and git worktree, surviving crashes and restarts, with a fully customizable Lua-based interface that updates without recompilation.
A comprehensive open-source guide for hardening Ubuntu Desktop 24.04/26.04 LTS systems with enterprise-grade security controls. Covers hardware protection, kernel hardening, sandboxing, network isolation, browser security, and anti-forensics techniques for journalists, human rights defenders, and security professionals across 17 languages.
Gravity Linux is a project using clean-room reverse engineering to bring Linux support to Apple Silicon M4 Macs, with the goal of upstreaming this support into the mainline Linux kernel and other distributions. The team plans to release their first version soon.
DeadLock OS is a Linux terminal puzzle game where players solve investigations using real shell commands like ls, cat, grep, and chmod. The game teaches practical command-line skills through escalating difficulty, from beginner tutorials to advanced sysadmin challenges, with puzzles requiring log analysis, permission debugging, and process inspection.
Cody Ho and Niklas built a fully OpenGL ES 3.0 compliant GPU driver for Apple's M4 Mac Mini and MacBook Neo in about one month by reverse engineering the AGX firmware ABI and user-space components using a hypervisor. The driver achieves high performance, running Minecraft at 200fps and supporting WebGL in browsers, and involved clean-room development techniques without accessing Apple binaries.
Brig is a micro VM sandbox tool that isolates code execution by limiting guest access to specific host directories, credentials, and network resources. The guest can only reach its home, named projects, delivered credentials, and internet; it cannot access keychains, SSH agents, or secret managers. Brig uses microVMs on both macOS and Linux for stronger isolation than plain containers.
A longtime Linux enthusiast who spent over a decade using various distributions and customizing his setup has switched to Apple's ecosystem, purchasing a MacBook and iPhone. He cites diminishing novelty in desktop Linux, convergence of desktop environments around flat design, and the practical appeal of macOS after using it for work, though he acknowledges the platform has its own shortcomings.
Fedora Linux 45 Beta was released on September 15, 2026, featuring kmscon console replacement, mandatory package signature verification, standardized secret management with oo7, and updated versions of Podman, Python, Go, and other development tools. The beta is available across multiple editions including Workstation, Server, Cloud, and IoT.
A developer built a Git server backed by object storage, discovering that Git's packfile format was the performance bottleneck. They created a custom columnar packfile format optimized for object storage, enabling efficient handling of production-sized repositories without requiring client-side changes.
A developer created a compact texting device by combining a $20 4G wireless hotspot, a Clicks keyboard, and a sharp display, then installed Linux using the OpenStick project and created a custom PCB to integrate the components into the Clicks case form factor.
A security researcher exploited a public Linux kernel bug in Google's kernelCTF challenge by manipulating CPU TLB shootdown behavior to maintain a stale memory mapping, then convinced the kernel to recycle the underlying physical page as a page table, ultimately gaining control to retrieve the flag. The exploit leveraged existing public vulnerability details rather than discovering a new bug.
Linux Doctor is a read-only diagnostic tool that runs safe health checks on Linux systems, identifies problems with clear explanations, and suggests fixes without modifying your system. It includes memory of previous runs to show what's new or fixed, and offers CLI, web dashboard, and desktop app interfaces across multiple distributions.
A technical guide for installing Armbian Linux on the ZTE B860H set-top box using a microSD card and HDMI boot dongle. The process involves flashing an Armbian image and U-Boot bootloader to the microSD card, then booting the device without requiring prior root access.
An opinion piece argues that Valve's Steam Deck is important for the broader tech ecosystem even for those who don't own one, because it demonstrated that gaming PCs don't require Windows and spurred significant open-source contributions to Linux, emulation tools, and desktop environments that benefit the community independently of Valve's commercial interests.
Linux From Scratch is a project providing step-by-step instructions for building custom Linux systems from source code. It includes multiple subprojects like BLFS for extending installations, ALFS for automation, MLFS for 32-bit support, and GLFS for gaming, along with documentation, patches, and historical archives.
