Tilex, our Phoenix port of Today I Learned, is coming really well. After a personal hiatus for RailsConf prep, I’m back full-swing. My coworkers have really been bringing quality commits as well, and I feel we are very close to a successful port.

We introduced some breaking database changes to our Phoenix port of Today I Learned on Friday; today I deployed them to staging. Resetting an Ecto Heroku database, with new seed data, turned out to be a little tricky, and I wanted to document what I learned.

Last week, I started a new project: porting Today I Learned from Ruby on Rails to Phoenix (Elixir).

Today I solved the Exercism Hamming Distance problem in Elixir. Here’s my solution.

Today I solved Exercism’s Sum of Multiples problem in Elixir. In this post, I’ll show my work solving this problem.

I’ve been working through the Elixir challenges on Exercism.io. Yesterday’s assignment was to implement a Run Length encoder and decoder in Elixir. Here’s my implementation.

I’ve been learning and using Elixir lately, and loving it. More than once, I’ve been asked some version of the question: why are you learning Elixir? What makes this language unique? I thought I’d take a moment and try to distill my rationale.

I’m learning Elixir, and today as an exercise, I was challenged to recreate Enum.sum using recursion. Here’s my solution.
