    x86 virtualization in your browser, recompiling x86 to wasm on the fly

    Fundamentally it's "just" a JIT that compiles to WASM. It's a ton of effort to build something like that, but I think fundamentally it's not an impossible undertaking.

    The JIT seems to be living there, so you can probably explore from there: https://github.com/copy/v86/blob/master/src/rust/jit.rs

    WRT speed advantage: compared to what?

    Online OR1K Emulator running Linux

    If the title is true, that would be a huge achievement. Unfortunately, the page says nothing about how it works and nothing about the speed advantage you get.

    For my emulator jor1k [1] I tried something similar years ago [2]. However I haven't continued on this topic because of priority shifts. But the potential speed advantages are astonishing. My proof of context reached more than 1 billion emulated machine instructions per second.

  • Klotho

    AWS Cloud-aware infrastructure-from-code toolbox [NEW]. Build cloud backends with Infrastructure-from-Code (IfC), a revolutionary technique for generating and updating cloud infrastructure. Try IfC with AWS and Klotho now (Now open-source)

  • daedalOS

    Desktop environment in the browser

    This is an awesome project! I've integrated it into my Desktop Environment in the browser so that you can drag on `.iso` & `.img` files and run them directly in the emulator. It also automatically saves states on close into `/Users/Public/Snapshots`. For networking I am using the same WebSocket proxy that v86 uses.
