I Must Learn Scala!
Scale is so terse, so flexible, and oh so cool. I must sit down and learn it properly soon. In fact I sort of cant wait :-).
I dont expect to be using Scala for anything serious any time soon (although you never know, do you), but I hope to challenge my way of thinking about code and design.
I'm starting to realize how much ground the Eclipse RCP (Rich Client Platform) actually covers . -Its really cool and really solid. The framework is mature and includes all sorts of enterpisy stuff. E.g. there was a Eclipse BIRT (Business Intelligence Reporting Tools) presentation at the conference, which showed a "from naught to reports and a nice report designer integrated in your app in 2 hours" demo. Quite convincing. Seeing that I've done much more .NET than anything else over last few years, this is foreign ground, but for LOB desktop apps it's differently very serious competition to WinForms. Must keep this in mind for coming projects.
Is Flex for Me? -Still on the Fence
And, BTW it was really fun to be out of my element for a few days!
