Teens and privacy: A new survey from the Pew Research Center’s Internet and American Life Project found that 81 percent of parents expressed some concern about how much information advertisers can learn about their children online. Parents also said they are concerned about how their children interact with strangers online.

The survey also highlighted that parents of teens are worried about how online use may affect the teens’ future academic and employment opportunities, and that nearly 70 percent of parents have concerns about how children manage their online reputations.

H-P charges Autonomy lied before acquisition: Hewlett-Packard took an $8.8 billion charge Tuesday after finding what it called “serious accounting improprieties” in its acquisition deal for the British software company Autonomy.

The deal was first announced by former H-P CEO Leo Apotheker, who told The Wall Street Journal that he was shocked to learn about the alleged deception.

“Looking back on the acquisition, which closed in Sept. 2011, the due diligence process was meticulous and thorough, and included two of the world’s largest and most respected auditing firms working on behalf of HP,” Apotheker said.

T-Mobile, MetroPCS: In a company blog post, T-Mobile said that it would “benefit substantially” from having access to spectrum from MetroPCS to build out its 4G LTE networks, and would better enable the company to compete with AT&T, Verizon Wireless and Sprint.

A merger would also allow T-Mobile and Metro PCS to have access to the latest devices, the post said, and improve the quality and breadth of its network coverage.

“Put simply, through this transaction, T-Mobile USA and MetroPCS will establish a new and aggressive value leader in the wireless market, benefitting competition and consumer choice throughout the country,” the company said.

Obama data: The Obama campaign has put together a rich database of data on voters from across the country — one that could benefit the Democratic party as it looks to future elections. As The Washington Post reported, Democratic candidates interested in the data include Virginia’s Terry McAuliffe, who is mounting a gubernatorial campaign next year.

The data collection combined with a flexible database program called Narwhal, allowed the campaign to be nimble as it ran through the massive amount of data collected by the campaign. It may give the party an edge in future elections.

“If this is all we do with this technology, I think it will be a wasted opportunity,” said Michael Slaby, the campaign’s chief integration and innovation officer.
