gpars ... and FindBugs, CheckStyle, etc.

I attended, at Gateway Groovy, the last half or so of Alex Miller's talk on gpars.
The little bit of the talk on ParallelArrayUtil was good.
His code example is at github.com/puredanger/gpars-examples
In the Q&A portion, Scala Akka was mentioned.

In Darryl Parks presented a good presentation and talk at the Gateway JUG. It was on FindBugs, PMD, CheckStyle, Sonar and XRadar.

He mentioned two good books:
Code Complete
Clean Code

During Q&A, appsight was mentioned as a good but expensive product for run-time code problem detection. Jack mentioned a problem he and a team looked into; they over-anticipated that the performance problem was with web services, when in fact it was with XPath.
Also, jester was mentioned as a good mutation tester; something with which you can test your junit tests.

Upcoming talk will be on JPA 2.0 (and it including hibernate criteriaquery).

What's New in Spring 3.0

Saw Jack Frosch's presentation tonight (at Gateway JUG) on What's New in Spring 3.0. Good stuff.

Grails: A Quick-Start Guide

Spring 3.0

I attended Ken Sipe's very good presentation on Spring 3.0 tonight (at St. Louis Java User Group). The part of the presentation on Spring MVC was especially interesting.

Best yet, at the end of the night I won a free entrance to No Fluff Just Stuff in St. Louis this Mar 6 - 8, 2009.
