Automating Daily Reports, because fuck it, really...

Each day at our company, developers are required to document their activities, painstakingly jotting down their daily work and future plans. A monotonous chore that I just really dislike.

So now, there's a scribe for that :

Code

r0xsh

Record

ffmpeg -f alsa -ac 2 -i pulse -f x11grab -r 25 -s 1920x1080 -i :0.0 \
-vcodec libx264 -pix_fmt yuv420p -preset ultrafast -crf 0 -threads 0 \
-acodec pcm_s16le -y $(mktemp --suffix '.mkv')

ffmpeg -video_size 1920x1080 -r 59 -f x11grab -i :0.0 -vcodec libx264 \

                ;;

// to run on each frame
function lerp(position, targetPosition) {

  position.x += (targetPosition.x - position.x)*0.2;

}
