Bandcamp is the best online music store, hands down. I've been using the site for seven years, and they continue to be my number one online music destination.
Their pro-listener, pro-artist business model is so simple, it's shocking. It doesn't involve tracking the snot out of users, injecting annoying ads, or trying to rip off artists. It's a simple, beautiful website that does what it sets out to do, better than anyone else.
Oh, and did I mention that the site is extremely fast, even on old hardware? Big props!
A new year is rapidly approaching, so I thought, what is something that I've been wanting to do for a while but keep putting off.
Answer: Learn Go. I've had my eye on Go for a while now, and I've been very impressed with the overall design decisions and goals for the language. I think they got a lot of things right, which is no easy task.
Initially setting up the Go environment was a bit kludgey, but that has been ironed out as the language has matured. I say, 2020 is my year to Go! (It's a bad pun, I know.)
