READING

Model correctly and write less code, using Akka Streams

Above all, do yourself a favour: write less code!
Nirmalya Sengupta (@baatchitweet)
stricter Scala with -Xlint, -Xfatal-warnings, and Scalafix

Compile, or compile not. There's no warning.
Eugene Yokota (@eed3si9n)
Elevator Control System using ZIO

With Scalaz-zio we can solve a real world problem, with a testable and simple code.
Wiem Zine
Easing Into Cats, And The Case For Category Theory Inspired Abstractions

No need to be apprehensive about adopting a library like Cats. You can start using it and start getting real-life benefits right away.
Dadepo Aderemi (@dadepo)
Get considered harmful

Some thoughts on Scala standard library design consistency.
Robin Hillyard
IO & Logging Capabilities

This approach keeps log entries as values, enables log aggregation, and supports diagnostic contexts, while also making logging easily testable.
Viktor Lövgren (@vlovgr)
Airframe HTTP: Building Low-Friction Web Services Over Finagle

airframe-http is a library for mapping HTTP requests to functions in Scala. This is not a web framework, rather, it can be used as a thin-wrapper over HTTP server libraries, such as Finagle.
Taro L. Saito (@taroleo)
Writing a Daytime Server with Akka Streams

And with that you’ve now implemented a 3 decade old tcp protocol using a hip, cutting-edge language.
Johan Andrén (@apnylle)
Monad Error for the rest of us

Learn about elegant way to generalize over error type.
Daniel Reigada
