  • Video codecs mostly work by tracking movement, predicting which pixels will change, and striving to only encode the pixels that actually change or change dramatically. In other words, compression looks for patterns.

    All of that goes out the window when you try to compress static. There are no patterns. It simply can’t be compressed. This isn’t a matter of the algorithms not being good enough. It’s a fundamental limit of information theory.

    Anything fancier amounts to embedding the intro into the compressor as a well-known pattern. And at that point, you’re better off just caching a 4K version of the intro as a standalone video file directly in the app.




  • 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.
