This is a really useful post about what you need to know about Cyclospora. I learned things. You will too

It's a real shit show out there: What we know, don't know, and what it means for you.

[Person 1 sitting at desk typing on laptop while Person 2 with shoulder-length hair stands behind.] PERSON 1: Aw man, speedrun.com removed my world record just because I listened to lateralus and ænima to get in the flow. PERSON 2: Oh, a copyright thing? PERSON 1: No, they don’t allow tool-assisted speedruns.](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:cz73r7iyiqn26upot4jtjdhk/bafkreiar3wsjy5rdmexkvbkh322xd77jkkihi55attsje5jknacobnmjti)
![your shell lets you run many programs (“jobs”) in the same terminal tab
programs can either be:
foreground
background
stopped (which is more like “paused”)
& runs a program in the background
for example I like to convert 100 files in parallel like this:
for i in `seq 1 100`
do
convert $i.png $i.jpg &
done
jobs lists backgrounded & stopped jobs
$ jobs
[1] Running python blah.py &
[2] Stopped vim
use the numbers to bring them to the foreground or background (like fg %2), kill them (kill %2), or disown them
when you close a terminal tab all jobs are killed with a SIGHUP signal
you can stop this with disown or by starting the program with nohup: disown %1 (job number goes here) nohup my_program &
a trick to kill programs if Ctrl+C doesn’t work
press Ctrl+Z to stop the program
run kill %1 to kill it (or kill -9 %1 if you’re feeling extra murderous)
a little flowchart
Three boxes, labelled “running in foreground”, “stopped”, and “running in background”
Ctrl+Z goes from “running in foreground” to “stopped” fg goes from “stopped” to “running in foreground” fg goes from “running in background” to “running in foreground” bg goes from “stopped” to “running in background”](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:nzrozayxq764zbgl4qtp5ald/bafkreigxoajfoayzbyucv22q6daqvpvcjlftkkhbeaajib5mbri3cwj5fq)
