  • The information I’ve seen regarding deep discharge life-cycle for sodium ion is that the latest tech is actually extremely good, at least according to this. I don’t see how the lower voltage is a problem, since for grid situations you’ll have step-up transformers anyway, and the batteries can just be hooked up in series to increase the voltage.

    They use abundant materials, will be much cheaper than lithium ion, don’t need to be actively cooled, and massively lessen the risk of rupture and fires.

    The low density per unit of weight isn’t relevant for grid storage, so they seem pretty ideal.













  • That’s a good argument, and as a fan of permacomputing and reducing e-waste, I must admit I’m fairly swayed by it.

    However, are you sure JPEG XL decode/encode is more computationally heavy than JPEG to where it would struggle on older hardware? This measurement seems to show that it’s quite comparable to standard JPEG, unless I’m misunderstanding something (and I very well might be).

    That wouldn’t help the people stuck on an outdated browser (older, unsupported phones?), but for those who can change their OS, like older PC’s, a modern Linux distro with an updated browser would still allow that old hardware to decode JPEG XL’s fairly well, I would hope.


  • The video actually references that comic at the end.

    But I don’t see how that applies in your example, since both JPEG and JPEG XL existing in parallel doesn’t really have any downsides, it’d just be nice to have the newer option available. The thrust of the video is that Google is kneecapping JPEG XL in favor of their own format, which is not backwards compatible with JPEG in any capacity. So we’re getting a brand new format either way, but a monopoly is forcing a worse format.



  • Jpeg XL isn’t backwards compatible with existing JPEG renderers. If it was, it’d be a winner.

    According to the video, and this article, JPEG XL is backwards compatible with JPEG.

    But I’m not sure if that’s all that necessary. JPEG XL was designed to be a full, long term replacement to JPEG. Old JPEG’s compression is very lossy, while JPEG XL, with the same amount of computational power, speed, and size, outclasses it entirely. PNG is lossless, and thus is not comparable since the file size is so much larger.

    JPEG XL, at least from what I’m seeing, does appear to be the best full replacement for JPEG (and it’s not like they can’t co-exist).


  • TL:DW, JPEG is getting old in the tooth, which prompted the creation of JPEG XL, which is a fairly future-proof new compression standard that can compress images to the same file size or smaller than regular JPEG while having massively higher quality.

    However, JPEG XL support was removed from Google Chrome based browsers in favor of AVIF, a standalone image compression derived from the AV1 video compression codec that is decidedly not future-proof, having some hard-coded limitations, as well as missing some very nice to have features that JPEG XL offers such as progressive image loading and lower hardware requirements. The result of this is that JPEG XL adoption will be severely hamstrung by Google’s decision, which is ultimately pretty lame.
