From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

if you could pick a standard format for a purpose what would it be and why?

e.g. flac for lossless audio because...

(yes you can add new categories)

summary:

photos .jxl
open domain image data .exr
videos .av1
lossless audio .flac
lossy audio .opus
subtitles srt/ass
fonts .otf
container mkv (doesnt contain .jxl)
plain text utf-8 (many also say markup but disagree on the implementation)
documents .odt
archive files (this one is causing a bloodbath so i picked randomly) .tar.zst
configuration files toml
typesetting typst
interchange format .ora
models .gltf / .glb
daw session files .dawproject
otdr measurement results .xml

Here's a little article which highlights jxl well. https://chipsandcheese.com/2021/02/28/modern-data-compression-in-2021-part-2-the-battle-to-dethrone-jpeg-with-jpeg-xl-avif-and-webp/

I do not think it's mentioned there, but I think webp and also it's indirect successor avif afaik, both lack progressive loading which is not optimal for website loading. It's has incremental loading which I think is akin the the old dial up time of loading top to bottom row for row. They proclaim progressive decoding is costly on memory and cpu, but progressive gives the best user experience imo.

Lastly a fringe issue, re-encooding multiple times. The good old reason why jpgs turn into trash over time because people encode instead of save images. Or because sites re-encode when uploading. Jxl wins here. It also is very easy to see why jpg turns into what it does rather quickly.

I also like the idea of incremental loading, even if it's not that relevant anymore. Also, I don't think your example of generation loss is enough as it's just one image, I would like to see multiple randomly picked images passed through the same process but if the results are the same as here or barely anymore loss than the best option for any given image I do think that's a good result to aim for.
