Grails Diary - Week 12 in 2014

23 March 2014

The biggest (almost Grails) news of the week must be the release of Java 8. It has created a bit of buzz in the community, and I've included a couple of Java 8 related articles in this weeks Diary. As Rob Fletcher noticed, the Java and Groovy syntax are now diverging with the Java 8 release.

Cédric Champeau has created a GR8 example of how to use Groovy and Geb, to make a solver for the (warning: very addictive) 2048 game.

Gaelyk has been released in version 2.1, and is available for download. You can also try it using the Lazybones templates.

Gr8conf Europe can be followed at Conferize. The lineup and talks already announced really looks great. Tickets are available here. The GR8Conf US looks equally interesting, and have a lot of speakers and presentations ready for the July 28-29th conference. If you can't wait for GR8conf, there are still tickets available for Greach later this week! I'll be there - catch me if you have comments or suggestions for the Grails Diary, or just wish to chat :)

If you are not already following @DailyGrailsTip on Twitter, you should consider it. It is doing a nice job of supplying tips and tricks, and recently updated the avatar to the tip of a pair of Grails Sneakers. The sneakers are by the way the reason for Tge Grails Framework using the #grailsfw tag on Twitter. Best tip this week is the Groovy-based DSL for working with remote SSH servers.
