As I’ve detailed odd and context-specific HTML, this is a look at CSS largely outside the specifications. Browser-specific hacks, technology-scoped syntax, and engine-exclusive snippets forged from questionable circumstances, corporate complications, and esoteric implementations.

University of Toronto ☛ The many load averages of Unix(es) in 2026
A decade ago I wrote The many load averages of Unix(es), where I attempted to cover the different meanings of "load average" that the free Unixes of 2016 used, because it turned out there was a significant divergence. Things have changed a bit since a decade ago (and also I may have misunderstood the BSDs a decade ago), so today it's time for a refresher with current links to kernel source code. I'm going to focus on Linux and the *BSDs because they're the most accessible to me. To summarize, everyone except Linux agrees that the load average counts only runnable processes (more or less); only Linux also includes processes waiting on certain sorts of things, especially disk IO.

Trynix - Test classic Linux tools without installing anything
You want to check something in an old version of Python, say the one from 2017, just to see if the bug you're hunting comes from there. Normally that means hunting down a Docker image or an old Python binary to run your tests. But with trynix, you click a link and boom, you've got a shell with your tool.
This site was made by Farid Zakaria, who's been tinkering around with Nix for years and calls it his " magnum opus ". Basically, an x86_64 Linux machine boots up right in your tab, with the requested package already sitting in the PATH. Nothing to install, no account to create, it just works directly in the browser.
