I like to play pianobar on a bluetooth speaker but don't always want to walk over to my desk to hit next, so I made a terse little web remote in go. Now I just whip it open in my phone. Took about 3 hours and then another 1.5 later to polish it up for sharing.'twas a fun little project that someone else might enjoy using.
Looks like in retrospect there are some pretty feature-full pianobar-web repos out there, but certainly none as simple/short.
