WebM to MP4 using FFmpeg

This FFmpeg command converts a .webm video file to a standard .mp4 file using the libx264 codec for video, aac codec for audio, and a CRF value of 22. The preset is set to 'slow' for higher quality encoding, and the audio bitrate is set to 128 kbps.

If the input and output filenames don't contain spaces, quotation marks or other special characters:

ffmpeg -i input.webm -c:v libx264 -preset slow -crf 22 -c:a aac -b:a 128k output.mp4

Using GitHub Codespaces is my new default for editing a static Jekyll site

3. Once it's launched, run the following in the terminal

/*  (Not so) simple synth based on Mozzi library and a bunch of pots.

 *  This code is derived from the public domain example of an 8 potentiometer

 *  
 *  Severely edited for clarity and configurability, adjusted to run with modern

 *  this sketch will auto-generate fake MIDI events and random parameters, so

How to change your commit messages in Git?

At some point you’ll find yourself in a situation where you need edit a commit message. That commit might already be pushed or not, be the most recent or burried below 10 other commits, but fear not, git has your back 🙂.

Not pushed + most recent commit:

git commit --amend

This will open your $EDITOR and let you change the message. Continue with your usual git push origin master.

# Arguments just need to contain a number and a bunch of words.
