I learned the hard way that the popular HTTP client for Elixir doesn't automatically decompress or re-encode responses. I had to fix it myself.

Structs and maps are easy to work with in Elixir, but if they are stored in the database as JSON and accessed via an Ecto Schema, it's not as clear how to query them. We're going to explore how to do that, and make it clear and easy.
Testing a scenario where an app sends an email is easy, but how do you test something random in an email, like a password reset token? When we test a function that intentionally returns random data, it's a little tougher.
Phoenix 1.3 introduces contexts, which has been met with some resistance. I've developed an application using it and learned some lessons.
Ugh... three lines for a simple text input for a form in Phoenix? How about one with Formulator?

Refactoring is scary. I've seen some comments on Twitter indicating that it's generally something really risky, sending tremors through the rest of the team. It's true, it's risky, but it's generally for the better. But I often need to refactor something a bit more scary: life.
I recently bought a MacBook Pro with a limited 256GB SSD. It's great, btw, but it requires me to now store all my music, movies, and archival-type files on an external drive. It scares me a bit to have all that stuff on a single USB-powered drive, so I also set up a network NAS that contains 2 mirrored 1TB drives (I salvaged these from my desktop that I sold to buy my MacBook). Enter problem: I'm lazy. I don't like manually backing everything up. I just want to manage the stuff I put on the external drive, not the NAS drive. Enter solution: BASH script, and launchd.
