I don’t really follow X, Bluesky, Instagram, TikTok, etc. so I basically live under a rock. Sometimes I ask dumb questions to try to understand people a little better. Apologies if my questions inadvertently offend anyone. I mean no harm.

    I made a custom Linux image to run inside a web browser. No particular distro, just a Linux kernel (compiled with a custom configuration to produce a tiny binary), a shell, and a few small apps.

    When reading from the filesystem, it made HTTP requests for each file (+ browser caching), so no need to load a disk image all at once. IIRC, I got the cold boot time down to <1 second (after assets were already cached from a previous load though).

    I also got NixOS to run in the browser, but even after stripping out as much as possible, it was still really slow due to systemd. (I’m not a systemd hater, resources are just very limited when running this way.)

    I used an x86 emulator called v86. It’s a very cool project 🙂
