Operating systems, infrastructure, emulation, and technical history.
How commercial Unix fractured across codebases and alliances while POSIX and the Single UNIX Specification preserved portable interfaces.
How USB combined one host-controlled bus, device discovery, shared connectors, power, and classes—and why adoption still took years.
How Usenet propagated discussions without one owner or database—and created enduring norms for threads, moderation, spam, and archives.
How IEEE radio standards, Wi-Fi Alliance certification, unlicensed spectrum, security repairs, and product naming built a mass market.
What PARC actually built, what preceded it, what Apple saw in 1979, and how research ideas became distinct Lisa and Macintosh products.
What WSL's automatic proxy discovery can transfer from Windows to Linux, where individual tools still diverge, and how to debug enterprise proxies safely.
Why a successful tar export can still contain application-inconsistent data, and how to build a WSL backup you can actually restore from.
What starts when the first Linux process launches in WSL 2, which configuration is read at each stage, and why a distro can fail before the shell even appears.
Using explicit mounts and clear ownership boundaries instead of pointing multiple WSL distributions at the same fragile private state.
Building or selecting a compatible WSL 2 kernel, configuring .wslconfig correctly, and keeping a working path back to Microsoft's default kernel.
