Tiago Fernandez has a nice writeup on a benchmark he did between Groovy, JRuby, Rhino and Jython. The verdict is generally a tie between JRuby and Rhino, with Groovy generally a second or third and Jython looking to be in last place on all 4 benchmarks. Personally, I would have liked to see Groovy 1.7 benchmarked instead of 1.6.7. Tiago acknowledges this discrepancy but points out that the 1.7 release notes don’t make any mention of significant speed improvements for 1.7. Here’s hoping that’ll change in the coming months, and the Groovy 1.8 (or 2.0?) will one day be the fastest around. :)

Grails and OAuth example from Matt Raible
December 28th, 2009Matt Raible has a nice write up on his blog about using Grails (1.2!) with his forked version of Grails-OAuth plugin and LinkedIn’s API. His live example is here (letting you log in with LinkedIn credentials or Twitter credentials), and the OAuth plugin can be downloaded from here.
New GR8 releases
December 27th, 2009We’ve been fortunate to have two new releases in Groovy world recently – Groovy 1.7 and Grails 1.2. I presume many/most of you already knew about these, but in case you didn’t, now you know. 
Thanks Groovy and Grails teams for your continued gr8 work!
I’m personally looking forward to the ‘named query’ support in Grails 1.2 (I’ve got a Grails 1.1 project I’ll be upgrading and refactoring soon!) and the improved memory usage in Grails 1.2 will be welcome as well.

July GroovyMag is now available
July 2nd, 2009
I think it’s safe to say summer is in full swing now (or winter’s in full swing, depending on your hemisphere). I just got back from a short road trip which included long stretches of too much AC, finding new radio stations, and dropped cell calls. During that trip I attended this year’s CodeStock in Knoxville, Tennessee. While CodeStock is largely a Microsoft-oriented event, I bumped in to more than a few people who were familiar with Groovy or were already using it on projects. This was certainly great to hear!
This month’s line up has something for almost everyone. Kirsten Schwark continues her monthly “Under the Hood” series with a first look at the typing system in Groovy. Understanding this can help you decide when it makes sense to statically type in Groovy, and when it makes sense to leave the typing out of your code.
Dave Klein brings us the latest news, and also covers the newly released Jabber plugin in this month’s Plugin Corner. Dave’s also got a new “Grails Primer” book coming out from Pragmatic Programmers soon. The beta book is out now at http://pragprog.com/titles/dkgrails/grails – check it out and give Dave some feedback on that if you haven’t already.
We’ve got some pieces from authors who are new to the GroovyMag writing team this month – Dean Del Ponte and Jorge Lugo. Jorge’s contribution delves in to the GParallelizer framework, helping you write parallelized apps with ease. GParallelizer and Groovy make for a powerful combination, and Jorge will have you up to speed in no time.
Dean Del Ponte takes us through writing an inline editor for your Grails data tables. By building on top of the existing jQuery library, Dean’s article demonstrates just what’s involved in adding this powerful UI feature to your next project.
Lastly, this month sees Robert Fischer bringing us a piece on how to use the logging functionality of Grails. His article stemmed from some discussions we had about the fact that many areas of the Grails documentation assumes a familiarity with existing Java components. With logging, there’s an assumption that a developer is familiar with Log4J, or can take the existing Log4J documentation and adapt it to a current Grails project. Some developers, like me, are coming at Grails from a non-Java background, and rather than answering my questions for the next three months on IM, Robert decided to address the basics of Grails logging in this month’s piece. Whether you’re new to Grails logging or not, I think you’ll still get some useful information from his piece.
Shawn Hartsock’s “Grails in a J2EE World” series will continue in our August issue.
