Felt like playing with Twilio, and not having released anything in a long time, I thought I'd push myself to finish something.

Since I happened to need to send & receive a fax, but didn't like to commit to a longer subscription plan, I made this website for doing that: https://5dollarfax.com/

I had a plan to promote it by writing a deep blog post about the contents of a fax handshake, and got pretty far into it, but at one point it required some signal processing knowledge I didn't yet have and the post languished.
