    It's worse than that -- there is not a single piece of hardware that implements RVA23 available to be bought on the market today. There are SoCs on the market that implement RVV (V…

    Most of the low-level pieces are in Rust, the TUI is written in Python and most of the remaining pieces are getting lowered down to the Rust libraries over time. (It was all Python…

    Firmware can sometimes get a bit complicated due to third party IP used and whether that can be opensourced, but within those constraints this is the ambition. I.e things like memo…

    Zero work? I guess memory fades quickly sometimes. Apple rented out DTK systems for $500 for developers to get their hands on ARM hardware and port their applications. Hardly zero …

    Good writeup, and lots of detail. But my immediate conclusion isn't "Signals are dangerous and let's go deep on the complexity thereof". Instead, my primary conclusion really is "S…

    LI-FI,,, It's sad how the ND-100/500 (and 5000+) families have almost completely disappeared, including online material about them. The IT department at my university was involved …

    FireWire (or at least OHCI-1394) had another fun feature: It exposed memory from the machine over the bus. https://www.kernel.org/doc/html/latest/core-api/debugging-vi... [EDIT: Th…

    Ex-Tesla employee here. I'm not going to comment on any of the statements because I know nothing of it, but I wanted to give one angle to the "performance bonus not paid out": Like…
