Another year, another year-in-review post. To be honest, I feel like any attempt I make to summarize what happened in the Clojure world this year is largely moot. Clojure has gotten so big, so — dare I say it? — mainstream that I can’t even begin to keep up with all the interesting things that are happening. But it’s…

Catching Native Apps
If you imagine a world where the sum of all things you can do with a computer is exactly matched, and locked down for all time with what you can do inside a browser, then the arguments for the web are persuasive. Why write for a specific platform when you can write for all platforms at once and gain the other…
