Caiwangqin's blog

Time is fast, 2011 is gone, 2012 is coming. In the past year, i spent more and more time on Twitter, Path and other social apps with iPhone, less time on Blogger, but i still remember this is my blog, my friends and readers may expect something here, so i come back here say Happy new year to everyone.

There's one thing i'm proud to mention we've done in 2011, It's Jetlun cloud portal, an Smart Energy and Home automation system, here is a screenshot for dashboard.


I hope 2012 is not the end of world!

It's good to use iPhone version Blogger post photo blog, and have location in blog post. Will Blogger's future be micro blog like Tumblr or Twitter? Not easy to input long text on iPhone, i'm glad to see the dead GWF doesn't block it so far.
