// `f` is assumed to sporadically fail with `TemporaryNetworkError` instances.
// If one of those happens, we want to retry until it doesn't.
// If `f` fails with something else, then we should re-throw: we don't know how to handle that, and it's a
// sign something went wrong. Since `f` is a good promise-returning function, it only ever fulfills or rejects;

• ffmpeg, plus whatever codecs
• parallel, for iteration that’s nicer than shell for loops or xargs
• run everything in zsh for leading 0s in numerical ranges to work

Details

Ember has great XSS protection built in. The HTMLBars templating library will automatically run any interpolations through htmlEscape for you. So
