Where does Feross get all those wonderful toys? He builds them with JavaScript, of course! BitMidi – a website for listening to your favorite MIDI files – is his latest creation. In this episode, Jerod “sits down” with Feross to learn all about it.

How do MIDIs even work? Why won’t they play on the web anymore? Can WASM save the day (hint: yes)? How does Feross get so many eyeballs on his creations? Is Preact awesome for building sites like this? What’s the future of BitMidi look like? Don’t ask us, listen to the episode!

Safia, Suz, KBall and Nick get together to talk about bugs!
