There have been many rumors floating around concerning a possible buyout of Yelp by Google, but it appears that at least a few details have escaped, painting this as a much more serious possibility. Pointing the needle to something north of $500 million, the acquisition would mean a substantial step into localized business for Google. "Google has been showing greater interest in the local business market in the United States. It has expanded its profile pages for local businesses, which include location and hours, maps and reviews from other Web sites. In June, Google gave local businesses the ability to manage what people see on their profile pages, similar to what Yelp does. Google has been reaching out to local businesses with simpler ways to advertise on the search engine. It is also distributing stickers that businesses post in their windows and passers-by can scan with cellphones to get coupons or information about the business. The deal between Google and Yelp could still unravel, one person said, particularly if another acquirer comes forward now that details have leaked."

As a follow-up to Epic Games' release of a free version of the Unreal Engine last month, the company has now posted over 160 video tutorials which demonstrate the various uses of the Unreal Development Kit. Roughly 20 hours of footage were created by technical education company 3D Buzz, with topics ranging from user interface to game physics to cinematics.
