I just saw @josevalim's post about the math behind the Elixir programming language's new gradual type system checking out. This post was tremendously exciting for me. Allow me to explain with this too-long post.

Suddenly increasing your focus on better testing and deployment this week? You're not alone, and PragProg can help. We've put two dozen titles in that category on sale, 40% off. (We've even added C Brain Teasers, just, well, because.) Use code BetterTesting at checkout, only at pragprog. Better than a gift card for coffee and a late night snack... Specific titles in the comments below.

Hey folks. I wanted to let you all know that I have accepted a position with Mechanical Orchard. I start next week. Thank you to everyone that helped this post find reach. Y'all showed up for me in a way that I can't believe and I couldn't be more thankful. #myelixirstatus

Ideally it's Elixir, but I'm open to other languages for the right team and company culture. I'm open to full time employment or short contracts.
