READING

Scala World 2017

Afterthoughts on one of the most important Scala conferences this year.
Mikołaj Koziarkiewicz
ENSIME: No Maintainer

In December, when my first child is due, I will give up my online hobbies to be with my family, and finish my book, Functional Programming for Mortals with Scalaz. Of most relevance to ENSIME is that I will, sadly, no longer have the time to maintain this project.
Sam Halliday (@fommil)
Basic Category Theory for (Scala) Programmers (Part I)

Category theory is a branch of abstract math. Why it gets so much attention from (functional) programmers?
Gabriel Claramunt (@gclaramunt)
Scala Patterns To Avoid: Implicit Arguments With Default Values

The problem happens when you try to mix both features of the Scala language that make sense if used on their own (although I’ll argue with that a little in a moment), but when used together they create a very serious problem.
Wojciech Langiewicz (@wlk_wojtek)
