kellyohair — 2007-11-16

Just a plug (and additional reference) on my December 2006 article on JVM TI at http://java.sun.com/developer/technicalArticles/J2SE/jvm_ti. I really had not expected this article to be very popular, but I was assuming that only people writing JVM TI agents would...

tmarble — 2007-11-13

Today marks l'anniversaire du Java Libre -- it's hard to imagine all that has happened in the past year. Fortunately Rich Sands provides a great chronology of open sourcing Java SE. Of all the work that has gone into open sourcing Sun's implementation of Java SE one milestone stands out clearly: Sun's choice of GPLv2 and the Classpath Exception for OpenJDK. Despite the overwhelming success ...

Kelly O'Hair: Working in a Mercurial World

kto — 2007-10-31

So how do you work with a Distributed SCM? There are many answers, the easy answer is that you clone the forest, make the change in your local forest, create the changeset and push the changeset. Well, that works. But maybe you are working on multiple fixes, and you don't want to repeatedly clone over the network (even if it is fast), so here ...

dfuchs — 2007-09-12

In my previous blog entry, I have talked about how to take advantage of java agents in order to start a custom JMX Connector in a Java application, without modifying the application.

2007-09-09

How simple-minded have I become? Patrick Logan holds a hammer to my knee and my immediate jerk: "by no means does that pattern matching look particularly readable to me" and "I can do it just as well in Java". Although that is indeed the case, it isn't Patrick's point and I also thought I had long given up on contests like these. It must ...
