Send SOS to twitter in one button

Nowadays location based applications become more and more popular. Maybe the simplest location based app is sending emergency message with your location. For example, if you go to a place with potential risk, when the accident happens, you might not have enough time to send SMS or make a call to tell where you are exactly.
My little project ttlite is for this: you can preset your SOS message and turn on GPS on your phone, in case the accident happens, you just push one button to send SOS with your location to twitter. You have known about twitter's great power in spreading messages instantly, right?

This winter in Shanghai

Last night it was very cold, this morning I found the wall behind the curtain was wet because of the cendensed moisture in the warm room.
It's sunny today, I went to a park nearby with my family.Suddenly we found ice slush, it's the first time I saw it in Shanghai. Very interesting. The photos are here:

JavaFX colorlines game (on JavaFX 1.2)

One of good things at Sun is that there are always new technologies to play with, even if it's not related to my daily job. In November, 2008, I did a simple implementation of colorlines game with JavaFX, of course it runs on JavaFX 1.0. 

Over one year passed, I know there's a lot of changes from JavaFX 1.0 to JavaFX 1.2. So today I decided to upgrade it. Fortunately, I don't need change one line of codes, it passed  compilation with JavaFX1.2 on Netbeans 6.8.  However, it had problem during runtime on Windows XP: running as applet is O.K., but running as web start did not show anything. Then I changed to ubuntu linux and opensolaris, everything worked fine. I checked the source codes and Java debug console, but could not find any clue, It's so weird. 

Anyway, JavaFX 1.2 showed faster than JavaFX 1.0. I put the codes to Google Code. If anybody can point out the problem I will  appreciate that  very much.

About this blog (why I am here)

I had several blogs, SDN China, msn live spaces, javaeye, and Sun blog. Due to various reasons (company rules, privacy protection, censorship, etc), I emptied or discontinued them.
Currently I decide to use blogspot.com as my blog site because it's free (free of charge and free to speak, no censorship), although blogspot.com is blocked by some countries, which means the users need to work around the firewall to read/write blogs on blogspot.com.
