In the recent past I’ve typically versioned software based on either its most recent tag or, for non-release versions, the commit short SHA–the seven- or eight-digit hexadecimal hash of the latest update. Because commit hashes are neither ordered nor intrinsically memorable, I’ll add the commit’s date in the form YYYYMMDD to remind myself at a glance how old is the thing I’m looking at. A major utility of this is to let me know I’m debugging the most recent version of the software–with automated deployments it’s possible some technohiccup or stray gamma radiation interferes and the updated app isn’t deployed yet.

The Wai project creates a simple API server where a user can update their location and current status, and their friends or colleagues can retrieve this information, and clients for this server.

The Minimal Database Access Library supports both SQLite and Postgres and helps take care of some of the drudgery of mapping objects to database entities--without the learning curve and frustrations of using an ORM.
