Elixir
Over Christmas, I decided to finally tackle learning Elixir. Since I learn new programming languages best by actually building something, I set out to implement a simple RSS reader/sync service, similar to Miniflux and FreshRSS.
Since I actually want to use this app, it needs to have a way to connect to my client apps (Reeder 5/Classic on iOS and macOS, as well as NewsFlash on Linux). Since the Google Reader API implementation is well-supported in most RSS clients, I set out to build an API compatible with the existing spec.
