When I install a new plug-in, I got this error:
"JFolder::create: Could not create directory plug-in"
Later, I found out the cause. The parameters in configuration.php are not configured correctly.
Please make these two lines in configuration.php pointed to the correct directory.

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.

I installed the Google PageSpeed. This is a good tool to optimize my websites.

It will give me a score of my website. Moreover, it will draw advice for fine tuning too! That is very cool!
