  • And it is not possible to “visualize 4D”

    Sure it is.

    • 3 spatial dimensions + time
    • 3 spatial dimensions + 1 color dimension (grayscale)
    • 2 spatial dimensions + 2 color dimensions
    • etc

    And that’s not even counting projection. All the time we interact with 3D data that’s projected to 2D (almost every photo you’ve ever looked at). There are similar ways to project 4D to 2D.

    (Not defending the video or anything, just pointing out that visualizing higher dimensions is something we know about for ages.)





  • [S]hareholders said they learned that CrowdStrike’s assurances about its technology were materially false and misleading when a flawed software update disrupted airlines, banks, hospitals and emergency lines around the world.

    I don’t see how they can make this argument.

    Falcon is a kernel module. When kernel modules fuck up, you get kernel panics.

    Sure, the layperson may not know enough about computers to recognize this, but it’s a basic enough fact about operating systems that an investor in a company like this should take the time to learn. It’s not like they hid that fact.

    If you invested in a company without knowing how their product works, that’s on you.

    However, Linus’s kernel was more elaborate than GNU Hurd, so it was incorporated.

    Quite the opposite.

    GNU Hurd was a microkernel, using lots of cutting edge research, and necessitating a lot of additional complexity in userspace. This complexity also made it very difficult to get good performance.

    Linux, on the other hand, was just a bog standard Unix monolithic kernel. Once they got a libc working on it, most existing Unix userspace, including the GNU userspace, was easy to port.

    Linux won because it was simple, not elaborate.



  • \1. Many retro games were made for CRT TVs at 480p. Updating the graphics stack modern TVs is valuable, even if nothing else is changed.

    \2. All of my old consoles only have analog A/V outputs. And my TV only has one analog A/V input. The mess of adapter cables and swapping is annoying. I want the convenience of playing on a system that I already have plugged in.

    \3. I don’t even still have some of the consoles that play my favorite classic games, and getting retro hardware is sometimes difficult. Especially things like N64 controllers with good joysticks.

    Studios don’t need to do a full blown remake to solve these problems. But I’m also not going to say the Crash and Spyro remakes weren’t welcome. Nintendo’s Virtual Console emulators toe this line pretty well.

    But studios should still put in effort to make these classic games more accessible to modern audiences, and if that means a remake, that’s fine with me.

    (I’m mostly thinking about the GameCube/PS2 generation and earlier. I don’t see much value in remakes of the Wii/PS3 generation yet.)








  • There are still issues with WearOS, but I think some of that is hardware. Last I heard, Qualcomm’s wearable SoCs were trash, but Samsung is in a good position since they have both the SoC fab and make the watch itself.

    Many industries are shifting to a model where Android is the de facto OS for consumer-facing interactions. It’s not well optimized outside of phones yet, but it is rapidly improving. Many cars run Android now, for example.

    I’m moderately optimistic about the next generation of WearOS devices.
