Been reviewing submissions for @jfokus.se and while I've seen a lot of great talks pass by, I can't shake the feeling there are some viewpoints missing. 😉

So don't hold back your quirky, silly, weird or serious ideas for talks and submit them anyway! sessionize.com/jfokus-2026.

I've started work on my "30 Years of Java" talk for @jfokus.se, and it's proving to be a lot of fun.
I just showed my son the Java ring and explained it had a computer in it. He did not seem convinced 😀
I've also got my PalmPilot up and running for the KVM and even a Livescribe Pulse smartpen.
