In-reply-to » Can you beat me at the circle game? 😂 https://neal.fun/perfect-circle/

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 I use to be a pot or more a day but have cut that back in the last 4 or so years to just 2-3 cups. Main reason was because I was getting jittery which didn’t happen before.

[$] DMA addresses for UIO

Even though I really do like the shell, I always use Dolphin to mount my digicam SD card and copy the photos onto my computer. I finally added a context menu item in Dolphin to create a forest stroll directory with the current date in order to save some typing:

Image

The following goes in ~/.local/share/kservices5/ServiceMenus/galmkdir.desktop:

[Desktop Entry]
Type=Service
X-KDE-ServiceTypes=KonqPopupMenu/Plugin,inode/directory
Actions=Waldspaziergang;

[Desktop Action Waldspaziergang]
Name=Heutigen Waldspaziergang anlegen…
Icon=folder-green
Exec=~/src/gelbariab/galmkdir "%f"

In order to update the KDE desktop cache and make this action menu item available in Dolphin, I ran:

kbuildsycoca5

The referenced galmkdir script looks like that:

#!/bin/sh
set -e

current_dir="$1"
if [ -z "$current_dir" ]; then
    echo "Usage: $0 DIRECTORY" >&2
    exit 1
fi

dir="$(kdialog \
    --geometry 350x50 \
    --title "Heutigen Waldspaziergang anlegen" \
    --inputbox "Neues Verzeichnis in „$current_dir“ anlegen:" \
    "waldspaziergang-$(date +%Y-%m-%d)")"
mkdir "$current_dir/$dir"
dolphin "$current_dir/$dir"

This solution is far from perfect, though. Ideally, I’d love to have it in the “Create New” menu instead of the “Actions” menu. But that doesn’t really work. I cannot define a default directory name, not to mention even a dynamic one with the current date. (I would have to update the .desktop file every day or so.) I also failed to create an empty directory. I somehow managed to create a directory with some other templates in it for some reason I do not really understand.

Let’s see how that works out in the next days. If I like it, I might define a few more default directory names.

@prologic@twtxt.net in this case it isn’t vendor lock-in. I believe they do it because the carrier “eats” the costs (the interest part of the instalments). The phones are fully unlocked.

I will return the two we got for parents, and re-buy them again, this time on an instalment plan. Why pay $2,000 up front when you can split the cost in convenient monthly payments, all interest free, right?
