Yahoo! Social offers a PHP SDK currently in Alpha stage. The main difference between PHP5 and PHP is the available storage. As the site states, the new implementation is more flexible because developers can store OAuth tokens in a PHP session, in a database, or in memcache. Requirements showcase OAuth, Open ID, OpenSocial, and JSON with its respective redirected links. Examples include fetching YQL, fetching social data, fetching people and activities with OpenSocial, and adding contacts. Tests offer functional examples and results as well. Despite the fact that the SDK is in a experimental stage, developers have the opportunity to plan social directory and contact applications in advance.
For those who love good food and great dining, a good restaurant guide is key. What would be even better is if that guide could tell you where the restaurant is, what it has on offer and what everybody's saying about it. That's pretty much what MenuMania does; it's a customisable, community-based restaurant guide for discovering new places to eat within New Zealand. MenuMania also provides the MenuMania API, allowing developers to access the database of restaurant information for display on other websites and applications.
In theory the rise of software-defined networking is supposed to give rise to a new class of applications that will give developers more control over, for example, location-based services. In actual practice no one is quite certain how developer will invoke SDN capabilities, but the folks at Hewlett-Packard are anxious to find out.
