While knowing HTML5 I could not miss CSS3. I'm already using properties like border-radius or box-shadow but while going through others I was curious about animation. Especially when there is bold statement that it "can replace animated images, Flash animations, and JavaScripts".

Lately Facebook forced all developers to use oauth 2.0 by setting by default oauth:true in FB.init();

The most important changes are:

• Cookie name is now 'fbsr_'. not 'fbs_'
• Cookie has more changes than you think ;o)
• perms are now scope - so now instead of writing in e.g. login button perms="email,publish_stream" you write scope="email,publish_stream"
• to get access_token we need to have `magic code` first
• if you're using some client-side scripting too, then instead of FB.getSession use FB.getAuthResponse - (thanks ajquick)

...

• the best way to avoid so many problems in the future - use PHP SDK from facebook or/and JavaScript SDK from facebook

Things you need to change are probably similar for other frameworks if you don't use SDK. I tested this solution for CodeIgniter 2.x. But it should work for earlier ver too.

If you need to know the latitude and longitude for the corners of the visible area of the google map, you'll probably use something like getBounds();

If you just need to refresh your page or content every x seconds you just need some javascript. I show you some basics with jQuery. 

Someday every developer get to the point where it’s time to use transaction in SQL. It’s really usefull thing. Honestly.
