  • They won’t all be interchangeable. They can have totally different max power delivery, and a device is free to require more (up to 240W by spec). The nice thing about USB-PD is it’s negotiated and a device won’t (shouldn’t) try to pull too much power for a given plug. So as long as everyone sticks to specs, they’ll be interchangeable so long as the supply can supply enough. If it cannot, at least a device should keep itself off as if a chord isn’t plugged in, or preferably have some sort of “supply too low” sign.











  • There is a diffuse gamma glow around the center. There are only a couple of paragraphs quoting the most silly versions of explanations: Dark Matter interaction and spinning neutron stars.

    The article offers no answers.

    IMO, it’s FAR more likely we just don’t entirely know how dense the region is and what atoms/particles are in it, and it could be as silly as interstellar particles getting excited from high energy particles that escape the SMBH accretion disc. Or some similarly ‘common’ thing.






  • AI isn’t even the first or the twentieth use case for those operations.

    All the “FP” quotes are about floating point precision, which matters more for training and finely detailed models, especially FP64. Integer based matrix math comes up plenty often in optimized cases, which are becoming more and more the norm, especially with China’s research on shrinking models while retaining accuracy metrics.
