This week was the week of Scala Days 2012. Rainy London was the stage for almost two full days of Scala talks, discussions, meets and greets with the people you know mostly by their Twitter name and chats with other Scala developers.
When you start your journey in the land of Scala, you'll often receive the friendly advice to not wander in the woods of Scalaz (pronounced Scala-zed), because there's nothing of interest for beginners there and you'll most likely get lost. It's certainly possible to get lost, but this article will show you that it's possible to pick just a few things that give you immediate benefit.
The subject of this trip is Validation: how to represent a computation which can either give a result, or a failure message. Or rather: how to represent a sequence of computations (each of which may fail) giving either a complete result or else a list of the failure messages.
Next week, after presenting at Jfokus, Peter Hilton will also present at the Scala Stockholm meet-up on 15 February.
On 6 January 2012, Lunatech hosted the Play!ground in the Netherlands - an event for developers interested in the Play framework. Here are the slides from the presentations.
