Free Code!

Oh, one more thing. There is FREE CODE to go with the Specifications article. Running code examples are available in the Subversion repository at Google Project Hosting. There is also a JAR-file ready to download and use as basis for your own specifications. If you hurry you can get one of the first ten JAR-files I give away (no, unfortunately they are not signed...)!

Specification Project at Google Code.

Specification Pattern as a Refactoring Tool

There was a time when this blog was about software development. Nowadays it just seems to be a lot of whining. So it is time to change that. I actually did write a post about the Specification pattern detailed in Eric Evan's book Domain-Driven Design. But formatting the code examples for this blog turned out to be more of a hassle than I could deal with; so instead you'll find it in the latest issue of PNEHM!, Citerus' newsletter on software development: Specification Pattern as a Refactoring Tool.

The Specification pattern is nothing revolutionary, but it offers a nice way of encapsulating business rule logic that tend to be sprinkled all over your average business application. It is useful as a modeling and implementation concept when building systems from scratch, but can also be a powerful refactoring tool. The article will show you how.

And while you're at it, make sure to read the other articles in this issue of PNEHM!. You'll find interviews with both Ken Schwaber and Jerry Weinberg as well as a piece on Grails (in Swedish). Some people say it's our best issue ever.

P.S. Don't miss our classes on Domain-Driven Design and Strategic Design this spring.

Domain-Driven Design classes spring 2008

I'm very happy to let you know that Eric Evans is returning to Citerus and Uppsala this spring to host a new set of Domain-Driven Design open enrollment classes.

New for 2008 is that we have extended the immersion workshop Putting the Domain Model to Work to four packed days of presentations, discussions, modeling exercises and coding! This year I will give this class together with Eric which I'm sure will be great.

Eric will also give the two-day class on Strategic Design.

New is also the venue; we will be hosting this event at the brand new Uppsala Concert and Congress Hall which I think will be excellent.

This time around we have discounted fees for early registration, so head over to Citerus now to sign up:
