@prologic@twtxt.net Oh, that’s cool! :-) Feeding magpies seems to be an Aussie thing, the Cutting Edge Engineering Australia videos usually also include a cute magpie feeding clip.

@bender@twtxt.net Off you go to the magpie hunt! We wanna see Florida pies!

@klaxzy@klaxzy.net I’ve had many SD cards die in Raspberry Pis. Really annoying. I’ve eventually switched to using a read-only rootfs. 🫤

Can you automate the drawing with a script? On X11, you can:

#!/bin/sh

# Position the pointer at the center of the dot, then run this script.

sleep 1

start=$(xdotool getmouselocation --shell)
eval $start

r=400
steps=100
down=0

for step in $(seq $((steps + 1)) )
do
    # pi = 4 * atan(1)
    new_x=$(printf '%s + %s * c(%s / %s * 2 * (4 * a(1)))\n' $X $r $step $steps | bc -l)
    new_y=$(printf '%s + %s * s(%s / %s * 2 * (4 * a(1)))\n' $Y $r $step $steps | bc -l)

    xte "mousemove ${new_x%%.*} ${new_y%%.*}"
    if ! (( down ))
    then
        xte 'mousedown 1'
        down=1
    fi
done

xte 'mouseup 1'
xte "mousemove $X $Y"

Interestingly, you can abuse the scoring system (not manually, only with a script). Since the mouse jumps to the locations along the circle, you can just use very few steps and still get a great score because every step you make is very accurate – but the result looks funny:

🥴

@aelaraji@aelaraji.com oh yeah! You will feel in heaven, me thinks, because that new machine will go around the Pi a few laps. Have fun, mate!

@falsifian@www.falsifian.org the reason behind his sporadic disappearances is that he runs things from a Raspberry Pi, at home, I believe. That impacts reliability, I figure.

I run Plan 9 on my server and my main home workstation (a raspberry pi). My “daily driver” time is basically split between that and a Mac (excluding time on my phone, i suppose). I think it looks elegant, too. :-)

This pi will now boot directly to ed if the gpio pin is grounded at boot time. ed(1)term v1. :-) http://txtpunk.com/edterm/

@lyse This was basically a trial/proof-of-concept for the real goal: a switch which, if on at boot time, causes the pi to boot straight to ed.

I made a gpio button on my raspberry pi which opens a new window running ed. I screwed up while testing it and launched maaaaany ed windows.

Dug out my old usb audio device and now my Plan 9 raspberry pi can play music. 💯

For sure. The pi progresses normally until it prints that it’s initializing the keyboard, at which point the keyboard spends ~30 seconds beeping.

I just timed it: 59 seconds for my Raspberry Pi to boot, 33 of which is waiting for my keyboard firmware to initialize. That’s just absurd.

Someone brought us pie for Pi Day. 💯

On the up side: I got my first successful comunication over i2c on Plan 9 on a Raspberry Pi today! Looking forward to playing with that more.

Thanks to a pointer from Richard Miller, got screen rotation working on my Pi 4s. Makes this absurdly wide display more practical.
