“You can never understand one language until you understand at least two.” – Geoffrey Willans
For years I've been developing mostly in JVM languages. Sometimes in other C-derived languages, which was both cool and easy.
A few months ago (due to career shift) I had to learn Go rapidly. While technically Go has keywords looking similar to C, many things are simply different and even unheard of in C-based OOP languages. Learning Go is a great journey and the best are these AH-HA moments, when doing things in Go I suddenly understood Java better.
Sure, during a single talk I won't teach you Go. Thing is: I don't event want to, as all I want is to show you some concepts in Go which can help you (just as they helped me) become better Java developer and understand why we need projects Valhalla and Panama. It's about leaving our comfort zone to get... more comfort.

Deep Dive
Another (half a) year has passed, another major Java™ version is ready to deploy on production.
Java was supposed "to be slow". However, Java turns out to evolve so fast, that next releases aren't just version bumps, but might significantly change the rules of the game. That's a good reason to check out what's new in Java.
