| this is related to my dinky cloud jukebox (https://github.com/pauldardeau/cloud-jukebox). that's a fancy | |
| way of saying a bunch of mp3 files stored in swift. | |
| i run it on a vps (droplet!) with 2gb ram and 40gb disk | |
| i continue to work on my cloud jukebox thingie | |
| primarily by adding more of my music collection to my little saio swift cluster on a vps | |

| it’s configured with standard 3 replicas (default) |
