Open JDK
Recently, I got a chance to build OpenJDK 8 on a Windows 7 host. Thanks to a detailed article "YAOJOWBI - Yet another OpenJDK on Windows Build Instruction" on http://weblogs.java.net/blog/simonis/archive/2011/10/28/yaojowbi-yet-ano..., I avoided many problems that could have cost me several hours to probe. Though it is almost complete and comprehensive to most users, I still came...
Old friends may want to gather in Brussels the weekend of February 4-5 for FOSDEM.

The month of July was a global gathering for all Java Communities around the world to say "Hello" to Java 7.
JUG-AFRICA also hosted multiple events to celebrate Java 7 (see the photos below). I have traveled in Africa to give technical Java7 talks and met with hundreds of vibrant Java and Android developers. In Dakar, Senegal (July 7), Brazzaville, Congo (July 9) and Kinshasa, DRC Congo(July 10).
As part of my sabbatical, in April, I will be in Alabama at UAB as invited professor.
A breaking change for me. No kid, no wife for a whole month.
In one way, I will have time to do some research I had to delay due to lack of time. But in another way,
I worry to have too much free time :)
So where should I go, what should I see, what should I do during this month in Alabama ?
