Speakers and talks

“Free Monads”, Alexander Gryzlov, (https://twitter.com/clayrat) Adform
--------------------------------------------------

In the previous meetup (http://www.functionalvilnius.lt/posts/2015-03-25-second-meetup-slides.html), Rolandas has warmed you up with the monad introduction and now it’s time for something more. Alex will present the very cool concept of Free Monads in Scala.

For homework reading:
* Excellent blog post on the topic (though in Haskell): http://www.haskellforall.com/2012/06/you-could-have-invented-free-monads.html
* Pretty much the same thing as above, but translated to Scala(z):

“Living without Objects”, Osvaldas Grigas (http://www.ogrigas.eu/), Inventi
---------------------------------------------------------

Osvaldas will show us how to stop worrying and flip your mind from OOP in order to model things in a functional style. Here's his abstract:

“Transitioning from OOP to FP can be quite challenging, not least because OO programmers are not used to thinking in terms of verbs instead of nouns. Non-hybrid functional languages do not allow falling back to class hierarchies, so one is forced to learn to think in terms of verbs and find other ways of doing polymorphism and composition. We’ll investigate some examples of that in Clojure.”

See you all soon!
