Cats Effect: IO

A data type for encoding side effects as pure values, capable of expressing both synchronous and asynchronous computations.
Stepping down as the maintainer of scalamacros/paradise

Recognizing that I’m getting less and less time to work on macros, in September 2017, I stepped down from my role as the maintainer of Scala macros. Today, it’s time to do the same for Paradise.

Accessibility of the Scala Compiler

This effort has already received some open-source contributions, and the Scala Center will work hard to ensure that these contributions are seen through to completion, as we experiment with effective ways to improve the output from the compiler through a screenreader. This work will be not be tied to any particular choice of screenreader technology or editor.

IO Monad and Monad Transformers for Rookies

This article is aimed at rookie Scala developers who want to take some first initial steps into a more monadic way of programming.
