Curated, ordered reading paths through the archive — start-to-finish routes through a topic, not just a pile of related posts.
FreeBSD From Zero to Production
Start from FreeBSD's origins and boot process, work through its two signature features (jails and ZFS), and finish with the firewall and troubleshooting skills to run it for real.
9 postsLinuxUnderstanding the Linux Kernel's Core Abstractions
The primitives that everything else on Linux is built from — namespaces, cgroups, systemd, the VFS — plus the OOM killer and eBPF, and one real panic to debug.
9 postsmacOSHow macOS Actually Works Under the Hood
From the XNU kernel's Mach/BSD hybrid design through launchd, System Integrity Protection, code signing, sandboxing, and XPC — the platform security model end to end.
9 postsWindowsWindows Internals: From Boot to Enterprise Management
Process internals, the registry, and the service model first, then the security model and the tools (Group Policy, PowerShell Remoting) that manage Windows at scale.
9 postsFreeDOSFreeDOS From Boot to Daily Use
What FreeDOS is and why it still exists, its boot sequence, the 640K memory constraint that defined the whole DOS era, and enough to install, network, and troubleshoot it.
9 postsSRE & DevOpsFrom Containers to Kubernetes in Production
Docker vs. Podman and what actually runs a container, then how Kubernetes schedules and networks workloads, how Helm manages releases, and how SRE practice measures whether any of it is working.
9 postsRetrogamingHow Emulation Actually Works
The techniques behind running old software on new hardware — interpretation vs. dynamic recompilation, why cycle accuracy is hard, what ROM dumping and preservation actually involve, and the legal reality behind BIOS files.
9 postsHaiku OSUnderstanding Haiku, BeOS's Modern Successor
Why Haiku deliberately isn't a Unix clone, its pervasively multithreaded kernel, BFS (a filesystem that doubles as a database), the Looper/Handler messaging pattern behind every app, and how to actually run it.
9 postsTech HistoryFrom ARPANET to the Web: How the Internet Actually Happened
A chronological walk from ARPANET's first (crashed) message through DNS, Usenet, and the Xerox PARC GUI, to the Web's public-domain release, its first browser war, and the bubble that followed.
9 postsWSLHow WSL Actually Works: From Translation Layer to Real Kernel
WSL's history and boot lifecycle, how it bridges two filesystems and lets Linux and Windows executables call each other, its networking modes, and the memory behavior (vmmem) that confuses almost everyone at first.
9 postsShell & TerminalShell Scripting and Terminal Fundamentals, in Order
Where shells came from and how bash/zsh/sh actually differ, then the mechanics — subshells, expansion, quoting, job control, signals — that most scripting bugs trace back to, ending in writing scripts that actually port.
