In other #eventemitter news: I needed an async emitter. There are a few out there (emittery, awaitable-event-emitter, garronej/evt, even eventemitter2 has something async), but they have the same “performance issues”* as other EEs.
*Performance is in quotes because you often don’t need it.

Every couple of years, I need a fast event emitter. I pull out my trusted benchmarks at github.com/Hypercubed/E...
to see which one is the fastest today. Interesting development this year! It looks like mini-signals is no longer the fastest, having been inched out by github.com/Morglod/tseep.

![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@jpeg)

I'm having a rough go of it lately, and have been thinking: everyone is going through something, and you have no idea what it is, or how it's affecting them.
Quote post this is if you're going through something, and maybe we'll all realize that we aren't as alone as we feel right now.

There are a few multidimensional libraries out there for #JavaScript; but most (maybe all?) are focused in numerics. StridedArray was built to effectively manage 2d arrays of any type. And #TypeScript first.
I'm happy to share StridedView! This library helps me efficiently manage 2D arrays in JS/TS. Originally created for game tile maps, but useful for any 2D data manipulation. Inspired by NumPy, but not limited to numbers. github.com/Hypercubed/s... #StridedView

What he said about Social Security payments has been repeatedly debunked - so the question isn’t whether he’s lying about this, the question is why.
What is this a pretext for? He and the GOP have long shown interest in going after Social Security. What are they going to try?
