SBT Tricks
Dear Richard: these are the SBT tricks you should have known about. They are the ones you wish you could remember just when you need them, but you don’t. So here they are written down.
Using slickless with Plain SQL
With shapeless HList support available for Slick, we can make further use of shapeless to reduce boilerplate code. This post explores how to do this for the Slick GetResult type class.
Upsert in Slick 3
An upsert means inserting a row into a database if it doesn’t already exist, or updating the row if it does exist. The Slick database library knows how to do upserts. This posts takes a look at the built-in support, and gives an example of what you can do if you need to roll your own upsert logic.
This is part of a series on Slick, for material in or being added to Essential Slick.
One Week with OS Maps
I like the Ordnance Survey maps, in particular the 1: 25 000 Explorer range. Intrigue by the recent launch of “download included”, I used the OS Maps app for a week. This is how that worked out.
Towards Browser and Server Utopia with Scala.js
At Scala Days 2015 in Amsterdam I talked about Scala.js, and in particular focussed on the great interoperability with JavaScript. This post gives additional links if you want to dig deeper.
Typechecking SQL in Slick and doobie
Querying a database is sometimes best done with hand-written SQL. Of course the trick is to find a way to avoid syntax and type errors at run time. This post will look at how Slick and doobie approach this problem.
Slick Query Enrichment
Query enrichment (or query extensions) in Slick can provide a concise way to express domain-specific logic. This gives extra flexibility beyond Slick’s combinators, such as map and filter. This post builds up an example micro DSL, showing the benefits in clarity and reduced repetition.
Introducing Essential Slick
Essential Slick is a new book we’ve been working on, which is now available for early access. That means, we’ll be making updates before we announce a final version, although all the chapters are available. This post tells you a bit more about the book and its origin.
Practices for Distributed Scala Teams
Jutta Eckstein’s recent presentation on distributed teams rang true for me. We’ve leaned much about distributed teams, about what works, and what causes issues. In this post I’ll note the challenges for new Scala teams, and ways to tackle them.
Notes from Software Architecture Fundamentals
I've been working through the "Software Architecture Fundamentals" course. These are my notes. They will probably make no sense unless you've taken the course.

How to integrate Papertrail's logging service into a Lift webapp.
