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:

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

because if you use a 40 kHz signal to "draw" a 10 kHz wave, the wave will have only four "pixels", so all the high frequencies have very low fidelity

As long as the audio frequency is less than half the sample rate, it is a mathematical function with only one (exact) wave that is able to fit all 4 points, so it is perfectly reconstructed. This video provides a great visualization of it https://www.youtube.com/watch?v=cIQ9IXSUzuM
