Lava Lamp for Hudson projects

Posted by kohsuke on June 25, 2007 at 11:02 AM PDT

Someone posted an article on Hudson Wiki that explains how to drive Lava lamps based on Hudson build status.

I've done a bit of extreme feedback device myself, but the great thing about this article is that it doesn't require any electronics

Introducing Metro

Posted by kohsuke on June 19, 2007 at 11:05 AM PDT

In the past few weeks, I've been mostly working on the launch of Metro, a web service distribution built around the JAX-WS RI and WSIT.

I think this move is a bit like the one we did with JWSDP, for those of you who remember.

Hudson interview on

Accessing maven repository from Ivy

Posted by kohsuke on June 11, 2007 at 5:57 PM PDT

Glen Smith on Hudson

Posted by kohsuke on May 15, 2007 at 8:06 AM PDT

Glen Smith apparently liked Hudson enough that he has done a Hudson talk to the Canberra JUG. His slides and audio are available for anyone. I wish if they could have recorded the whole thing to video.

Oracle oc4j 11 ships with the JAXB RI

Posted by kohsuke on May 14, 2007 at 8:53 PM PDT

JAXB RI just got one step closer to the world domination :-)

Vivek told me that Oracle shipped OC11J technology preview (OC4J is their application server), and that apparently bundles the JAXB RI.

My JavaOne report

Posted by kohsuke on May 14, 2007 at 2:38 PM PDT

I enjoyed talking to a lot of people during JavaOne, some I already knew and some I didn't.

I did two talks this year.

Glassfish sites get a new theme

It's always when I'm super busy when I decided to work on random things that take too much time.
