I am planning a small compute job tracking/notification service. Initially it will be for my own personal use, but may eventually be offered publicly.
I plan to write the server in Racket (likely leaning heavily on [0]) and have it interface with a sqlite database. Since the load will be quite low, I'll put it on a small VPS.
I've enjoyed using Racket for some small projects and am interested in scaling up my abilities to use it in a larger project. Based on my reading the first half of [0], it seems like something that's achievable give my other constraints (real job, etc.).
