Welcome to the weblog of Peter Maas. Here you'll find various posts related to stuff I like (like my kids and espresso) and stuff I do (like developing software).

Last Tuesday I gave a ‘introduction to Scala’ presentation during the monthly ‘Tech Tuesday’ at Ebay/Marktplaats. After going through the slides I did some live test driven development. I think I managed to get some more people interested! Introduction To … Continue reading
While writing my internal SQL DSL example I stumbled upon this blogpost about a Type-safe Builder Pattern in Scala a couple of times. One of the issues I have with that code is the unnecessary use of mutable state in … Continue reading
Following up on my previous post on writing an internal SQL-like DSL for Scala I decided to bite the bullet and implement a ‘real’ parser for a subset of the SQL language to create the object tree from a SQL-like … Continue reading
I’ve been playing around with Scala again lately. Writing a (internal) DSL or a fluent api was still on todo-list. Instead of writing some arbitrary language for a made-up domain I decided to pick a language and a domain I … Continue reading
