    macOS largely _does_ bake this into the OS, and it is annoying. They also provide a way to turn it off for specific applications (including, for example, Terminal.app).

    It had me looking up the specs for the Atari Lynx II that I had as a kid in lieu of a more popular handheld.

    Then, if you want to know about using optical switches to connect Clos segments without a fixed spine, check out Google's "Mission Apollo" paper: https://arxiv.org/pdf/2208.10041

    Huh, now I feel like I should scan my dog. Thank you.

    For most of my time here I used exclusively Chrome OS, and switched to it for personal use as well. My daily driver for years was a bright red Samsung Chromebook Galaxy (the first …

    I would not argue with this, but I regret to confess that I am merely an engineer. I no longer aspire to artistry.

    This is largely where I'm ending up, but I started at the other end. There is value in prose that carries your literal voice when the audience is _people who know you_. There is ne…

    I'm trying to put together what you could possibly mean by this -- rolling coal is fundamentally about spite. In isolation, nobody _wants_ their vehicle to spew black smoke. It onl…

    You're not wrong, but PnP including the configuration basis for PCI which still sits at the config space layer of the latest and greatest PCIe. That's the piece I find so significa…

    I don't remember if Plug-n-Play shipped with the original Windows 95 (it's certainly there in the final OSR), but that was a pretty big shift from the manual IRQ and port mapping d…

    Columbo is anything but a failure, though, and the audience knows that. His genius is leveraging humility to convince killers that he's a bumbling idiot, while in reality he's onto…

    It's so far from comedy that I couldn't make it through the series. When it comes up in conversation, I tend to describe it as "grief porn."

    Yes, highly recommend Reynolds, generally, although the third Rev Space book takes some fortitude to get through.

    I realize this isn't the meat of your post, but you ate a lobster sandwich at Walmart? I cannot help but think of https://youtu.be/Pj-D0jc17D0?si=BiEGWr9aacGdAkGW

    You might have even better precision if you stay away from CPU0 and also set idle=poll in your kernel command line. Lots of things (including other interrupts) often land on CPU0. …

    I agree with nearly everything except your point (1). Periodic polling is awkward on both sides: you add arbitrary latency _and_ increase database load proportional to the number o…

    That would make sense. My first thought was "Arc'teryx will probably adopt this immediately." They (and similar brands) are already pushing as hard as they can on seamlessness or v…

    This actually makes sense from a spec perspective if you want to give enough to allow hardware to catch up with the specs and to support true interop. Contrast this with the wild w…

    In my world, we won't let a system boot with production credentials unless the IOMMU is enabled. This is enforced by a greatly enriched TPM (and it's willingness to unwrap credenti…

    I was surprised to see a mention of the Carnegie Science Center's Omnimax and the year 1978 -- my recollection was that this theater didn't open until I was both alive and cognizan…
