Getting Java EE and Scala to play together

Proposer: Ant Kutschera

Rather than adopting all the new frameworks and tools surrounding Scala, I'd like to stick with everything I know well, but at the same time use a more expressive language, with its new concepts, APIs and libraries. The hope is that the resulting software is easier and cheaper to maintain, and that programmers can have fun.

I'm interested in hearing other peoples experiences, although I can talk a bit about what works and what doesn't, if required.

Good (and bad) experiences in free and non-free software projects

Proposer: Kim Tucker 08:05, 27 August 2012 (UTC) (but probably wont convene as I have a different role - any volunteers? - or simply merge above)

Extending the above (Bad experiences in FLOSS projects) to include

  • Good/bad experiences with non-free/proprietary software projects
  • Good/bad experiences with projects using a combination of free and non-free software (are there any which don't)?

Discussion: JAVA is OO, but are we doing OO...?

Proposer: Jesper Udby

JAVA is an Object Oriented language. When I started programming in JAVA in 1998, OO was the new black. We did OOA/OOD/OOP, told customer to do OO and whatnot. But the stuff I've been doing the last couple of years is not really OO as in the old days. It's more like services (procedural) using Objects to package information. Are the original OO ideas dead, not important, not realistic or am I just on the wrong projects? :-)

Tools and tricks for Rapid Application Development

Proposer: Ignasi Marimon-Clos i Sunyol 18:14, 22 August 2012 (UTC)

What tools, tricks, workarounds,... do you use to get a mockup with a CRUD, persistence and some web UI up and running. Few weeks ago I attended a Hackaton after a looong time without doing so and altogether with 4 more colleagues we barely did anything useful in almost 8 hours. We dealt with a connection poll issues, domain model development, JDBC, JSON conversion... Then, few days later a friend told me he achieved the same in one hour and alone. I noticed we used the wrong approach. Am I using the wrong approach at work too? How can OSS help me? What would you suggest as the starting point? Roo for java? Play for Scala? This discussion could easily be held immediately before the Friday's Hackaton or even during it.

Java and packaging

Proposer: Pantelis Koukousoulas 09:15, 31 August 2012 (UTC)

Traditionally there is a certain amount of friction between the Java community and Linux distributions over packaging issues. After giving examples for how this leads to real problems for the users in the end, we will look into good development practices that make packaging and collaboration with distributions much easier.
