To reduce load on my current project I had a look into reducing the number of requests fired at the application server. Many pages in the application trigger multiple DWR calls resulting in Tomcat generating heavy load on the servers.
One of the sollutions I came up with is batching DWR calls, which reduces the number [...]

Yesterday a colleague asked me whether it is possible to automate compression of javascript code in a web application (the current project has a total of about 150kb of javascript for some of the pages). I decided to look into the issue a bit...
There are tons of offline javascript compressors/obfuscators etc. but the ones using [...]

Today the mailman brought me a big brown envelope containing my official, signed certificate... Although Danielle thinks Sun could have done a better job on the quality (it looks like a simple inktjet printout) I'm still proud of it; and since I haven't got other news to post, here it is!

The small Rails app which I wrote for my wife broke down completely just after the installation of the new version of Rails (the 'mandatory' 1.1.5 and 1.1.6) by Dreamhost.
Couldn't get it to work at all, and no sensible logging info was produced...

While going through some Spring 2.0 documentation on using dynamic languages in combination with Spring I noticed an example of a Spring MVC controller written in Groovy. I fiddled arround with it a bit, the refreshable bean feature makes it really cool... now I can edit my controllers in a running application server!
Since I like [...]

I managed to get some insects to smile at my camera just long enough to get their portrets taken:

Today I passed the CX310-055 exam, which means as much as:
I am a 'Sun Certified Programmer for the Java 2 SE Platform, Standard Edition 5.0'

I scored a wopping 90% (59% required)! yeah!

While trying to relax for the upcomming exam today I took the camera out in the morning sun to take some close-ups. I think this one worked out particularly well:

Today the Canon EOS350D we ordered arrived. During the day Danielle mailed me some nice shots she made while experimenting... soon Sjoerd's weblog will be packed with hi-res 8 megapixel SLR pictures
But after dinner I had a go, and took a couple of shots of my espresso machine. I think some of them [...]
