I've been using IntelliJ as my Java editor instead of Eclipse - and I absolutely love it! So much so that I bought a license for all of JetBrains' programmer editors! I'm still learning how to use all the functionality of IntelliJ, but I am finding my productivity has dramatically increased a few days after I started using it.

Deep Learning

The more I use Deep Learning, the more I am amazed by it. Some things which would be hard to do programmatically are easy with the right Neural Network. It feels like we are just starting to scratch the possibilities.
