Most of my open-source work, these days, is focused on two projects. The first is a library for handling disparate calendar systems without having to know anything about how any of them work. It can translate dates and times between supported calendars, for dates over 140 billion years into the future or past, and times as small as Planck Time. Still a lot of calendar systems to add support for, though, and programming languages to expose it to (it's written in Go, but has a C shared library and a PHP extension available around it), so there's plenty to work on still.

The second project is more ambitious. It's an open-source clone of Nanobox, a development and deployment toolset now owned by Digital Ocean. The version being cloned is hosting-provider-agnostic, and builds infrastructure via configuration rather than code. DO is working to adjust it to a DO-only and Dockerfile-driven approach, but many folks wanted to keep access to the existing approach instead, especially those hosting on other providers. So, I've begun the work to satisfy that demand.
