There are a number of ways to create a pdf file by using open source software. For example, openoffice can export their document files into PDF. But How's about others file type? For example, how can I export a web page into PDF?
I found the best way is getting a PDF Printer driver. I just need to open the file and print it into a PDF Printer. Then it will "print" into a pdf file. I am using PDFCreator to do this task. It is free and opensource.

We built a tool to check network information in your Android. It will find out all internal IP addresses and the external address. That is very useful for your developer and to do security audit.

I found some friends who are not in MSN for years. But yesterday, they suddenly came online again! They are always online too! Moreover, their MSN photo changed to a sexy girl. They will send me a "Happy Holidays" message too! Then they will send another message asking about dating. I know those friends well, these should be their actions. I think their accounts hacked. Be aware!

There are a lot of rumors said Google will release Nexus Tablet very soon. I am not sure that is true or not. But I found Google need to have a flagship tablet. I have a lot of friends switched to Android Phone camp from iPhone. But in the tablet side, most of the people are still using iPad. I believe Android tablet has not won much in tablet market share.
In addition, I am an Android App developer. We have a dev phone which is Nexus One. That is a standard to follow. But we still have a dev tablet yet!

WE NEED a NEXUS TABLET!!!

I found Acer will release their new Tablet, Iconia A200. That is cool. It has Android 4.0. I hope it will get more market share. Moreover, finally, its design is not too boring. We can choose Titanium Gray or Metallic Red.
