The API is still a draft and may change before the release of Play 2.3 @mandubian and I talked about this Architecture and general and the new validation API at pingconf in January. You may want to skip the first 30 minutes, and jump directly to the API. This article sums up what we said there, and explore the validation API a bit deeper. Why validation ? When you think about a web application, yo
The previous post was mostly about programming "in the small" where the primary concern is making sure the body of code in the method does what it's supposed to and doesn't do anything else. This blog post is about what to do when code doesn't work – how Scala signals failure and how to recover from it, based on some insightful discussions. First, let's define what we mean by failure.

Written by two of the best-known participants in this development, Conceptual mathe- matics is the first book to apply categories to the most elementary mathe- matics. It thus serves two purposes: to provide a skeleton key to mathematics for the general reader or beg
