Based on my cheatsheet, GNU Coreutils, sed, awk, ImageMagick, exiftool, jdupes, rsync, jq, par2, parallel, tar and xz utils are examples of commands that I frequently use but whose developers I don’t believe receive any significant cashflow despite the huge benefit they provide to software developers. The last one was basically taken over in by a nation-state hacking team until the subtle backdoor for OpenSSH was found in 2024-03 by some Microsoft guy not doing his assigned job.

Also, ISO 8601 has some handy rules for expressing time lengths and periodicities.

Week numbers are convenient for projects in which key delivery dates are often expressed in his many weeks out they are.

I am fond of a partial shuffle algorithm I wrote in Bash for my music playlists that often preserves neighbors of the input list in the output list.

• Blue: input sequence.
• Red: complete shuffle.
• Green: partial shuffle.

The result is like skipping through my media library in order but occasionally randomly enabling shuffle to jump to a new place. Since the input list clumps albums together and since albums often have a similar vibe, if I want several similar songs of a particular feel to play one after another, I just have to manually advance through the outputted playlist until I hit a song that has what I’m looking for; then I can let the playlist continue automatically since each subsequent song is likely to be similar to the previous song (until another random jump occurs).
