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

this is a misconception about how waves are reconstructed. each sample is a single point in time. But the sampling theorem says that if you have a bunch of discrete samples, equally spaced in time, there is one and only one continuous solution that would hit those samples exactly, provided the original signal did not contain any frequencies above nyquist (half the sampling rate). Sampling any higher than that gives you no further useful information. There is stil only one solution.

tldr: the reconstructed signal is a continuous analog signal, not a stair step looking thing
