Server-Sent Events (SSE) is part of HTML5. SSE is a simple, undirectional communication from server to browser. It allows server to push data to client once a connection is established.

While parts of the cloud IT that are still being hyped are changing rapidly, the whole segment is not past the hype yet. The cloud report  that Gartner published 9 months ago still holds true today.

Java User Groups
Not too long ago, I actually was planning to attend this year's geecon conference, in Krakow, Poland. But, various events intervened, and I had to cancel. So, I'll have to just pretend it's the third leg of the Java conference hopping trip across Europe that I wish I could have taken this year (the first two stops were Jfokus and JavaLand).
geecon's workshops actually happened earlier today;...

Inaugural JavaLand in Germany
It took trains, planes, and automobiles to get there. I had heard Germany ran some great conferences, but JavaLand was promised to be outstanding. Kevin already did an interview with one of the organizers, Markus Eisele, about why JavaLand is different. (https://weblogs.java.net/blog/editor/archive/2014/03/01/java-conferences...) But, I got to see first-hand if they...

While looking at the bar graph from most recently completed Java.net poll about Java 8 implies a fairly strong consensus, in actuality I think this poll implies that there's quite a lot of disagreement on which aspect(s) of Java 8 are most important for Java/JVM developers going forward. A total of 245 votes were cast in the poll, and two well thought out comments were posted. The exact question...

Just now, I went to the Barnes and Noble web site and searched for "Raspberry Pi" books, and 70 books were returned, all of them genuinely about...
