Today, my facebook app in android got updated. In this version, the speed is improved a lot!!! Moreover, it changed notifications, friends and message windows into a tab, rather than a popup window. That is easier to read. I love this version! That is very cool! I suggest to get it upgraded as soon as possible!!!
WordPress 3.5 is released. I found the major updates are in Media Manager. The interface looks more beautiful! Moreover, according to their release notes, The admin is Retina-Ready. I recommend you get your wordpress upgrade.
I have jquery to show and hidden some div when the page is loaded. We found those div in some pages will affect the page description in some search engines. That is strange. Finally, we found the solutions. Hiding all div by default, when the pages is loaded, then using jquery is to show the div we need.
