sbt-jol plugin launched

sbt-jol plugin announced

This week Konrad Malawski shared a new plugin for a trivial way to inspect OpenJDK’s Java Object Layout of Scala classes.

Suggested information to digest this weekend:

The functional programming community has no shortage of excellent conferences and talks. Here are just a few that were recently released that we recommend checking out if you missed them the first time:

Matei Zaharia & Michael Armbrust:

  • Spark Summit West - San Francisco, CA

Jan Pustelnik:

  • Cool Toolz in Scalaz and Cats Toolboxes
  • Scalar 2016

Jan Pustelnik shows that “the two libraries: Scalaz and Cats widely held to be cryptic, hermetic and full of scary Mooonads in reality contain lots of easy to use components ready to be embeded in your code to make it shorter, clearer and easier to maintain. We will look at certain constructs from pragmatic point of view as just “Design Patterns” that happen to match ideally functional programming style.”
