of course i wouldn't regard any other opinions! this isn't my first time using grok, i know exactly how it's supposed to work

there's a mask process in qr code generation. the masks aims to try to make it look like uniform noise, so you don't end up with blocks/lines of pure white or pure black. so you won't end up with any recognizable symbol in the usual algorithmic generation

some more detail: it will use one of these patterns to invert some pixels until it finds one that results in more or less uniform noise.

it will also add a set of pixels in a designated mask identification zone that instructs the decoder which mask was used

i did have issues recently trying to capture from a selection on multiple displays when each display is a different scale factor.... i haven't had time to figure out how to fix that, for now i just capture on my main display only

i have this script on a keybind.

uses rofi, slurp and gpu-screen-recorder

modify as needed. i dont remember where i got it from originally

#!/bin/env bash

recorder_check() {
	if pgrep -x "gpu-screen-reco" > /dev/null; then
			pkill -INT -x gpu-screen-reco
			notify-send "Stopping all instances of gpu-screen-recorder" "$(cat /tmp/recording.txt)"
			cat /tmp/recording.txt | wl-copy
			exit 0
	fi
}

recorder_check

SELECTION=$(echo -e "record selection\nrecord eDP-1\nrecord DP-4" | rofi -dmenu -p "󰄀 ")

VID="${HOME}/video/recordings/$(date +%Y-%m-%d_%H-%m-%s).mp4"

case "$SELECTION" in
	"record selection")
		echo "$VID" > /tmp/recording.txt
    # Get selection geometry
    read X Y W H <<< $(slurp -f "%x %y %w %h")

    # Get monitor info (JSON)
    MONITORS=$(hyprctl monitors -j)

    # Find the monitor containing the selection and extract its scale
    SCALE=$(echo "$MONITORS" | jq -r \
      --argjson x "$X" --argjson y "$Y" '
      .[] | select(.x <= $x and .y <= $y and
                   ($x < (.x + .width)) and
                   ($y < (.y + .height))) | .scale')

    # Calculate physical coordinates
    PX=$(awk "BEGIN {printf \"%d\", $X * $SCALE}")
    PY=$(awk "BEGIN {printf \"%d\", $Y * $SCALE}")
    PW=$(awk "BEGIN {printf \"%d\", $W * $SCALE}")
    PH=$(awk "BEGIN {printf \"%d\", $H * $SCALE}")

    # Format geometry string
    GEOM="${PW}x${PH}+${PX}+${PY}"

this title is so confusing. if scientists or doctors have developed a new treatment, then it seems strange to me that the woman, the patient, is the subject of the headline instead of the doctors.

i originally read it as the woman had developed a treatment, and it seemed unfair for them to just call her a woman and not a scientist.

anyways have a nice day
