Transition from OO to Functional Design - with Clojure (Osvaldas Grigas)

For the vast majority of everyday programming tasks, objects and classes are an awful abstraction. And yes, encapsulation is hurting us more often than not.
But as we transition from OO to functional programming, do we need to unlearn everything? Do we start from scratch, diving right into monads, Category Theory and sophisticated type systems?
No! That's *not* what FP is about. Its essence is beautifully distilled by Clojure's simplicity. Much of what we've learned about good design, composition and polymorphism is still applicable, only with a twist.

Can you trust your tests? (Vaidas Pilkauskas and Tadas Ščerbinskas)

Nobody argues these days that unit tests are useful and provide valuable feedback about your code. But who watches the watchmen? Let's talk about test code quality, code coverage and introduce mutation based testing techniques.
