This afternoon, I gave two presentations for the nice folks at 42 for their Knowledge Transfer meeting, at Rotterdam's natural history museum. Here are the slides.

Drools)]]

In search of the perfect programmer (PDF, 4.2 MB) is a short presentation, to get things started. This is a light-hearted look at the diversity of programmer backgrounds, and a serious point about what that means for programmers, and the people who hire or manage them. At least the jokes got a few laughs.

Drools)] (PDF, 639 KB) is a technical introduction to Drools Expert, the rules engine in JBoss Rules, based on the example of a simple decision service, and focusing on what the code looks like. The decision service source code is available from the earlier article link:/2010/01/04/how-build-decision-service-using-jboss-rules-execution-server[How to build a decision service using JBoss Rules Execution Server], the last of three articles that explain the decision service example in more detail.
