I’ve been invited to give a talk at Scala World 2016. I’ll be talking about generic programming with shapeless, in particular about automatic boilerplate-free derivation of type class instances.

I hope the talk will be a useful companion to Sam Halliday’s Shapeless for Mortals workshop from Scala Exchange 2015. I’m also planning a surprise announcement, so stay tuned :)

I teamed up with Sofia Cole to talk at Scala Days about our experiences moving a team from Perl to Scala. The video is up on Youtube and is embedded after the break.

My latest adventure in conference speaking was a two hour hands-on workshop at Scala Exchange 2015, entitled Essential Slick: Hands-On with Slick 3.

Slick is routinely difficult for new Scala developers to pick up. This workshop provides a broad overview of the main concepts in the library, with more in-depth information available in Richard and Jono’s new book.

Due to equipment difficulties we didn’t record the workshop at the conference, so I’ve included a complete screencast after the break.

I re-ran my Functional Data Validation talk from Scala Exchange at Scala Days in Amsterdam last month.

It’s mostly the same content, but for variety I dropped the section on running parallel rules and replaced it with a section on _lifting_: changing the level of abstraction to allow us to combine rules directly, instead of combining them by combining their results.
