As is traditional, the attendees of Devoxx vote on certain topics on whiteboards. Each result must be treated with care - there is no validation process, and only a fraction of the 3500 attendees actually bother to vote. Nevertheless, the results can be interesting.
What version of Java do you use at work right now?
A high level question focussed on Java at the day job. Java 8 hasn't surpassed Java 6 yet, but it is doing pretty well. Remember that Java 7 is End-Of-Life in April 2015!
What IDE do you use?
A sense of how the IDE market is looking. The interesting data point is how Eclipse is falling - compare with 2008, where Eclipse led IntelliJ by almost 2 to 1, and NetBeans by almost 4 to 1. Sadly, the absolute number of votes is a lot lower than 6 years ago, so be careful with comparisons.
Beyond this, I heard various people comment on IBM's apparent withdrawal of funding for Eclipse IDE and what that might mean looking forward.
What JVM language are you using?
An attempt to see what languages people are using. Whenever this is asked, it is always an opportunity for advocates of a language to push hard, so again take the results with a good pinch of salt:
Is merging Scala into Java a good idea?
An odd question with a predictable answer - WTF!
An open question that showed a clear dominance for Angular.
Is this the end for Angular?
Angular 2.0 - "no migration path, not backwards compatible". Whether this is factually correct or not, this was the question asked.
What desktop UI technology have you used in the last 3 years?
A sense of where the desktop UI is today. Given that JavaFX has only been truly useful in Java SE 8, its not a bad showing for FX.
How do you create WebApps?
|Ruby on Rails||2|
|By hand, with love||2|
|Struts v1 or v2||11|
What one thing would you add to Java (your top priority)?
A traditional Devoxx question, with a long shopping list of answers, as always. Note however that Brian Goetz indicated strongly that properties as a language feature is not happening.
|Better handling of null||33|
|Safe null dereference||23|
|Interpolation of strings||22|
|Solve expression problem||2|
|Algorithmic data types||2|
|Cluster aware JVM||1|
|Free$ embedded support||1|
|Generators and co-routines||1|
|Operator overloading||1 (plus 2 minus 1 !)|
Lots of interesting, and no doubt slightly dubious, statistics to examine. Use with care, and congratulations to the Devoxx team for another great conference!
