The new version has a couple of interesting new things like internationalization out-of-the-box, thread-safe!, and JRuby becomes more and more a serious platform for Rails. Just great news, I guess I will spend the weekend Rails ... http://juskewycz.com/2008/11/ruby-on-rails-22/ I am kind of a performance geek, I like it lean and fast. Although I have to admit that in many cases optimization is not useful or not relevant (I learned a couple of lessons in this area), it is always interesting. As my focus more and more shifts to ... http://juskewycz.com/2008/11/smushit-use-it/ NetBeans 6.5 is available! I use 6.5 for 3 months now (beta testing ...) and I have to say that 6.5 is quite a good release. Here is the official announcment with all the new stuff. There is also an introduction video online. http://juskewycz.com/2008/11/netbeans-65-final/ I am currently working on a product called TimeWhale. TimeWhale is an online time tracking service. Of course it (will) supports all kinds of devices (usual suspects like Mobile Devices, Web, Desktop, ...). TimeWhale will be different to competitor services, e.g Basecamp, because its focus is only on time tracking ... http://juskewycz.com/2008/11/timewhale-beta-registration/ A couple of days ago I received my new MacBook Pro!

I was a 60 % Windows and 40 % Linux user and my forecast ... http://juskewycz.com/2008/11/java-sources-and-documentation-under-mac-for-eclipsenetbeans/ I had quite an interesting bug hunting last week in one of our extern engagements. In summer a memory leak was discovered in a new used third party library. Back then, we started with testing using Java profilers (Java SDK ships a good enough profiler - visual vm). Surprisingly, we ... http://juskewycz.com/2008/11/beware-the-classcastexception-a-tale-of-a-native-memory-leak/ This part will be a short one because I have to pack for my vacation. Yes, I will leave this cold and miserable weather, heading south to fill up my energy again (I am running on solar power). Last time we switched from a static approach to an instance based one ... http://juskewycz.com/2008/10/sometimes-hashmaps-are-enough-part-three/ The previous post shows how to implement a very simple and static approach to create Singletons using a static "Singleton" class. Now it is time to refactor our solution and make it more flexible. First, I want to get rid of the static context. Static is very simple but also restrictive ... http://juskewycz.com/2008/10/sometimes-hashmaps-are-enough-part-two/ I guess we have all heard about how bad static Singletons are and how Dependency Injection (DI) helps to make our application flexible beyond crazy. One common thing to do with DI is creating and using Singletons. I have been working a lot with DI frameworks in the past, mostly ... http://juskewycz.com/2008/10/sometimes-hashmaps-are-enough-part-one/ The great new look and feel for Swing applications, Nimbus, is according Jasper's blog (the 'father' of Nimbus) done.

Here a picture from the new look (screenshot is borrowed from Japser :) ) Thank's Jasper and ... http://juskewycz.com/2008/08/nimbus-is-ready-for-prime-time/
