The time I spent three months investigating a 7-year old bug and fixed it in 1 line of codeI originally told the story over on the other site, but I thought I’d share it here. With a bonus! \ I was working on a hardware accessory for the OG iPad. The accessory connected to the iPad over USB and provided MIDI in/out and audio in/out appropriate for a musician trying to lay down some tracks in Garage Band.
