  • x86-64 is a CISC architecture

    In many cases it’s actually RISC under the hood and uses an interpreter to translate the CISC commands and run them in the most optimal manner on the silicon

    ARM and RISC-V absolutely scale up to multi-hundred watt server CPUs quite easily. Just look at the Ampere systems you can rent from various VPSes for example

    The big benefit that ARM and RISC-V have is they have no established backwards compatibility to keep carrying technical debt forwards. ARM versions their instruction sets and software has to be released for given versions of ARM cores, and RISC-V is simply too new to have any significant technical debt on the instruction set side.

    Atom cores were notable for focusing the architecture on some instructions then other instructions would be a slog to execute, so they were really good at certain things and for desktop use (especially in the extremely budget machines they got shoved into) they were painful. Much like how eCores are now. They’re very carefully architected for power efficiency, and do their jobs extremely well, but an all eCore CPU is a slog for desktop use in many cases









  • Licensing is weird especially in schools. It may very well be practically free for them to license. Or for very small numbers of computers they might be able to come out ahead by only needing to hire tech staff that are competent with Windows compared to the cost of staff competent with Linux. Put another way, in my IT degree program every single person in my graduating class was very competent as a Windows admin, but only a handful of us were any good with Linux (with a couple actively avoiding Linux for being different)








  • The idea of dropping off a pod en-route to independently land is nice though

    Hey it’s slip coaches all over again!

    Real talk, I could see something like this adding some efficiency, but I can’t imagine these trailers landing at a regular commercial airport without a crew and power to abort the landing and circle back when the landing looks to sketch.

    Maybe these slip trailers might land at dedicated/specific landing sites where they have the risk tolerance for an unmanned, potentially uncontrolled super-heavy glider landing, but it’s still high risk to anything on the ground on its flight path should the unmanned glider crash



  • The town I live in renovated a park to have a gigantic playground, and every nice weekend day I’ve been there there’s tons of kids and parents there. On Halloween there were tons of kids out despite it being around 0F out that night. But random weeknights? I don’t see kids playing in yards much. I don’t see kids riding their bikes to convenience stores to get snacks. I think the risk acceptance of parents has shifted a lot plus kids are more able to occupy themselves with fondleslabs so they have multiple reasons to not go outside
