Grails Diary - Week 22 and 23 in 2014

10 June 2014

The diary this time covers two weeks, as the last week was GR8conf EU week, and I didn't have the time to write it, being one the crew for the conference. 

The last couple of weeks have offered a new release of Groovy: 2.3.2 . The previous two on the 2.3 branch generates faulty bytecode for inner classes, so an upgrade an a recompilation with the new version is recommended.

There have been lots of other releases in the Groovy community:  Griffon 2.0.0.BETA , Gradle 2.0-rc-1 , and Ratpack version 0.9.5

Groovy now runs on Android, as Cédric Champeau demoed during GR8Conf. There have been quite a bit of twitter activity on this, and Gregor Petrin has made a Flappy Bird style game as a demo.

The GR8Ladies in Minneapolis is running workshops for women interested in Groovy, the next one is at june 28th.

 

A few notes from GR8conf

The presentations I went to was impressive, and probably forgetting a lot, here are a few thoughts on the conference talks.

I attended Lari Hotari's very first conference talk with the title "Ratpack and Grails 3", and it was a great debut, later I also attended his "Performance tuning grails applications", the later also a general reminder on how to do performance tuning. 

Göran Ehrsson was impressive in demoing his work on a CRM system based on lots of plugins handling each their separate part of the application. It was a nice talk on architechture, with an convincing demo.

The most enternaining (and WTF generating) session was Noam Tenne and his Groovy Puzzles, catching lots of traps, pitfalls and end cases. If you find a small example that would fit as a problem, please email them to puzzlers@jfrog.com, the best ones are promised a cool Jfrog T-shirt! 

All the talks will be available as videos, once procesed, and the one I'm looking forward to the most is Rob Fletcher and his "Idiomatic Spock" talk. He mentioned afterwards that it was one of his best experiences as a speaker, and he is pretty good. I did not see the talk, but have heard it was fantastic.

Coolest gimmick award definitely goes to Cédric Champeau, for live merging the pull request for Groovy support on Android during his "Developping Android Applications with Groovy" talk. 

Next years GR8conf EU will be june 2nd.- 4th. so mark your calendar already now :)
