job control

wizardzines.com/comics/job-c...

(from The Secret Rules of the Terminal, which is out now!)

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”

I have always wanted something like an #ssh connection to the #iot devices I work on. Today we published about how to use #Golioth RPCs and a simple front end to do just that.

Did you know: if you installed Rust with rustup, you already probably have the "Embedded Rust Book" locally. If you run `rustup doc` in your terminal, it'll open the bookshelf with all the docs installed already, including the main rust books as well as the embedded rust book.

Here's an original piece -- Other Selves ( raynayx.com/2025/02/02/o... ).

It reflects on how we're usually overwhelmed by our circumstances but attempt to meet the moment every now and then.

We express our joys in sad verses
And when sad days come along,
We are unable to find our voices
We are unable to summon Akpalu‘s songs

You will see us do the dance of warriors
When there’s absolute peace within
And when war times come, we’re full of terror
We’re unable to channel Gemedra from within

You will hear us dole out ancient wisdom
When the judges have yet to sit
And when our kinsmen stir up a storm,
We are unable to find Ʋenya‘s ancient wit

But when you see us in a contemplative mood
Humming deep yet calm tunes for our loves,
Know that the boiling pot has shown all what’s for food
And the still river may harbor a crocodile that starves

I chatted with the embedded team at @raspberrypi.com about the #RP2350 on The Amp Hour. It's an amazing "dual dual-core" part that is finding its way into many products. We chatted #hardwaresecurity and #lowpower, as those were key enhancements over the #RP2040.
