• October 19, 2024 math Check whether an angle is between two other angles

  Weirdly, I've had to do this a lot recently: given an angle, determine whether it's bounded by two other angles. Technically, this is always true — just go the other direction around the circle — but usually I care about going in a particular direction.

  If you use git on a Mac, chances are you've accidentally committed a .DS_Store to a repo. I used to reflexively add .DS_Store to all my .gitignore files to avoid ever repeating that mistake.

• January 28, 2024 logic Send stereo output through specific output channels

  This probably works for many audio interfaces, though in this case I'm using a Quad Cortex. When I have my interface hooked up to Logic Pro, I want to route stereo output to the specific output channels that are connected to my speakers.
