GR8 in the US is a one day conference dedicated to the software language Groovy, software development frameworks Grails and Griffon, and related technology. It will be held April 16th, 2010 at the Holiday Inn Bloomington I-35W, 1201 West 94th Street, Bloomington, MN 55431. Guillaume Laforge is the Groovy project lead and co-author of Groovy in Action will be the keynote speaker. Venkat Subramaniam, founder of Agile Developer and author or co-author of the books .NET Gotchas, Practices of an Agile Developer, Programming Groovy: Dynamic Productivity for the Java Developer and Programming Scala, will be delivering the kickoff speech.

The trends are up this month for Tiobe, Dice and Indeed. Grails Jobs showed a slight loss. The Tiobe rating is at the highest level it has ever been since I've begun tracking it. The rank (position) is not, however. After two straight months of declines across all keyword searches on Dice and Indeed, they both showed gains across all keyword searches.

Note that I have slightly altered the way the data is presented. For periods where there was no data, as in the Tiobe numbers from October, I've used zero for the relevant numbers. I felt this was a little better when looking at the month to month changes. I also ignored the fact that there is a several month gap in the Dice and Indeed data, thus comparing July numbers to February numbers. This will correct itself in a few more months. Finally, I've set the negative changes to red, hopefully making upturns and downturns easier to spot.

This is a non-scientific survey. It is meant to give the interested reader a general idea of trends within the GR8 technologies job market. Results from keyword searches of job boards should be considered carefully as the results represent the number jobs containing the keyword in the description. The numbers from GrailsJobs represent the total number postings by month. The numbers from Tiobe are pulled from the survey published this month. The numbers from Dice and Indeed represent the results of keyword searches as of the day this survey was published. Suggestions of other sources of job market information are always welcome. Please comment on this blog post with any suggestions you may have.
