Right now I'm working in a team on the  belysio project.

I'm very keen on HDTV - High-Definition TeleVision broadcasts. Unfortunatelly the satellite broadcasts itself in Poland are very poor. There is little of such HDTV channels and the stuff being broadcasted there is either not interesting for me (football or some other stupid sport) or is repeatively bloadcasted (like discovery which has only several nice HD programs - but more is coming).
Anyway there exist lots of sites where some HD movies can be downloaded - that saves my day ;).
If you'r looking for some good info site about HDTV - here you can find one I visit quite often.

Now you never have to answer the question: Where are you?

Belysio is a Social Radar and a Geo Journal in one, showing you where your friends are, and what they're doing. In other words, it's the very first simple tool that demonstrates the advantages of "location" as an extra layer to your communications, offering you a delicious sense of "presence" and "proximity" with the friends, family members and business contacts to in your phone's address book - to whom you have given permission to see your location. You are in control of this.

All you need is a regular, modern cell phone with web access. Belysio is the first location based service that doesn't require geo positioning technology. They simply compiled a database with all known phone masts in the world, and through that you can, if you want to, automatically let everybody know where you are.

Belysio offers many extras:
- address book synchronization
- instant messaging via your choice of IM service - MSN, Yahoo!, etc.... even Twitter
- photo album to share with mobile/on-line contacts,
- location based google & wiki search,
- integration of your social networks, including LinkedIN, Zing, Netlog, Facebook, etc.
...and loads of cool features to come!

Seriously fun. Surprising practical.

Two new (early 2008) pages has been created: one containing API referrences links to Java Mobile APIs, and the second one is a download page for Nokia S40 platform application (e.g. Nokia 6020) - Week Planner.
As well a JavaScript Calendar Widget - fully localized and easy to extend - can be accessed, which can be easily used for selection of any valid date.

Usefull links to JavaScript memory leaks examples/discussions has been added under: JavaScript Memory Leaks - useful links
A new Tips part has been developed as well recently. It contains some usefull JavaScript/DHTML/JSF/Java tips and problems I could not find answer to easily in the Internet. Currently this part contains the following entries:

As internet means being always up to date I decided to make some opensource projects of mine. One of the projects is on a Java developer site java.net. It is about creating a GUI interface that can be plugged to any rendering engine (raytracer). The raytracer interface is being attached as an adapter and any raytracer engine that user wants to use has to have its adapter implementation. By default I'll try to attach default adapter implementation for PovRay. The next project is as well hosted on Java developer's site. Its name is propertiessynchronizer: PropertieSynchronizer and its main goal is to easy the process of properties files translation. It has some intuitive (hopefully) GUI implemented in Swing - just see it yourself here using JWS.

This project is still in very early stage as there is no time to sit down and push it forward even a bit. If you are interested in seeing the project and downloading it's source just follow the link to this project. It is called raytracerShell and is placed under javadesktop/javadesktop-incubator.

Lately I also was forced to take a look at JSF (Java Server Faces) specification. Having it read through and seeing some examples what I still miss out of it is some JavaScript support and more functionality on a client side. I decided to make some support for it in some of mine JSF Components I would like to introduce. I decided to make first a DatePicker component. It will make great use of clientside JavaScript functionality and is supposed to be very easily enhanceable and changeable concerning its look&feel.

As I also bought myself a new phone lately I also made a small Java demo application that can be run on it. It is a 3D cube that can be rotated and zoomed. This app is Series 40 app and unfotunately the cube is wireframe only as I couldn't find any fill draw method in the API and implementation of the fill method myself was a little bit too much for that small trial app. If you are interested in downloading this app and running it on your phone fill free, just follow this link to download JAR archive or type in "http://baton.pop.e-wro.pl/3DCube.jad" in your phone's browser.

Soon I'm also trying to start implementation of a simple Mobile Game that can be run on my 'Nokia 6100' phone. It is supposed to be something like a "River Ride" (riverride) game from old 8-bit ATARI machines. As I had one and I liked it very much I'll try to do it.
