AWS Lambda is a service that allows you deploy a function to the web. There are no servers to maintain, and billing is based on the compute time your function uses.

At the end of 2015, Amazon launched a set of AWS Lambda blueprints to help developers get up and running with Lambda. These consists of Python and JavaScript examples, based around integrating with Slack (“chat-based DevOps”, in their words).

But Amazon omitted to mention the JVM. This post fills the gap and shows you how to use AWS Lambda with Scala and Slack.

What a start to the year: the Typelevel summits are coming! The call for papers is now open, you can buy tickets for yourself and others. There are bursaries available for speakers and attendees. This post explains all…

Hi,

It’s almost Christmas! If I’ve learned one thing about the true meaning of Christmas from my children, it’s that it’s about loot—preferrably big piles of it—and the anticipation of said loot.

If you are the significant other (or want to treat yourself at Christmas, which I’m not ashamed to admit I do) read on!

My workshop at Scala Exchange was entitled “Essential Slick: Hands-On with Slick 3”. In my experience, Slick is routinely difficult for new Scala developers to pick up. This workshop provides a broad, brief introduction to the main concepts in the library, with more in-depth information available in Richard and Jonathan’s book. You can find a video of the talk and links to the code samples after the break:

At Scala Exchange 2015 I gave a workshop on building interpreters in Scala. Code and slides are here, though future development will take place here. The workshop covered untyped interpreters, GADTs, and ended with the free monad and free applicative.
