Every couple of years I settle on the general design for a full-stack application which I then use to explore various technologies and architectural patterns. I refer to these as my exploratory applications. In my 2014 post RecipeBox is Live I discuss the public release of one such application.
A short time ago I made public my latest exploratory application, TrackIt. In conjunction with the code release I created an 8 minute walk-through video. This is the first such video I've ever made. It's not perfect but I'm fairly satisfied with the results.
I continue to evolve TrackIt. Currently I'm finishing up a service implementation written in F# using Giraffe. Perhaps more on that later.
