We'll start this week with Google's Eric Schmidt who is testified on Capitol. Several US senators have accused Google of giving search preferences to its own suite of services over competitors, but Schmidt denied that his company's manipulating search results.

Yelp's cofounder and CEO said that Google's search practice is hurting its business. He questioned if Yelp could succeed today. Asked if he'd start Yelp in the current environment, he said, "I'd find something else to do."

On a more positive note for the company, Google Wallet officially came to Nexus S 4G phones on Sprint's network this week. The phones also need NFC or near field communication, which is the way the phone communicates with the electronic payment system, called PayPass, at store checkouts. When a customer pays with Google Wallet at one of the PayPass terminals they're required to enter a pin in the application to enable payment. Google used a clip from the popular sitcom Seinfeld to promote the service.

Customers can also store loyalty cards and coupons in the phone that can be used during checkout. Google said that eventually the app will be able to store transit cards, boarding passes and tickets.

Forbes published its richest Americans list and Bill Gates is on top with a net worth of $59 billion. In a distant 2nd place is Warren Buffet with $39 billion and then Oracle CEO Larry Ellison in 3rd place with $33 billion.

11,000 libraries across the US can now loan e-books to users of Amazon's e-reading app. There's no list of all the libraries that offer books so check your local library to see if the service is available. I tried the service through the Boston Public library, which is accessible to any Massachusetts resident, and in just a few minutes I had a new book delivered to my Kindle cloud reader and the app on my Android phone and iPad. The books in Boston can be borrowed for up to 14 days, after which they expire and the library typical has a limited number of licenses per book.

We told you a few weeks ago about how Netflix planned to split up its streaming and by mail DVD service. Netflix CEO Reed Hastings has finally come clean, admitting that he messed up in communicating the change. Netflix streaming service will keep its name, but the DVD by mail service will be spun off and name Qwikster. Users will manage their queue through Qwikster.com and users will also be able to order video games. Ratings will stay on the sites of origin meaning that your love of Breaking Bad on Qwikster won't help Netflix recommend Mad Men to you.

Panasonic's Evolta robot is at it again. This year the little robot will compete in the Ironman Triathlon in Hawaii, a grueling course of swimming, biking and running.

The competition starts on October 23 and we'll of course keep you posted on the results.

NASA experts say that a 6 and a half ton defunct satellite will plummet to Earth around September 23. The chances of debris hitting you on the ground: about 1 in 3200. But to put that in perspective, those odds are a lot better than being struck by lightning, which is about 1 in 1 million. NASA expects 26 large pieces of the bus sized satellite to survive the temperatures of re-entry and the debris is expected to fall over a 500-mile area.
