In the US alone, 40% of food is thrown out, partly because of confusing date labels, telling consumers to "use by", "sell by" and "enjoy by" a certain time.

Some of the dates are not about safety but taste, says Dana Gunders, a food scientist from the Natural Resources Defence Council (NRDC), which has issued a report saying much of the food labelled bad is actually perfectly edible.

Since 2010, the National Security Agency has been exploiting its huge collections of data to create sophisticated graphs of some Americans’ social connections that can identify their associates, their locations at certain times, their traveling companions and other personal information, according to newly disclosed documents and interviews with officials.

Almost everything about the agency’s operations is hidden, and the decision to revise the limits concerning Americans was made in secret, without review by the nation’s intelligence court or any public debate.

The NSA has released some details of 12 incidents in which analysts used their access to America’s high-tech surveillance infrastructure to spy on girlfriends, boyfriends, and random people they met in social settings.

One such analyst working on foreign soil started surveillance on nine phone numbers belonging to women over five years, from 1998 to 2003. He “listened to collected phone conversations,” according to a letter from the NSA’s Inspector General to Senator Charles Grassley released today.

A new paper has gone searching through historic trading for these sorts of glitches and ended up finding a lot of them—over 18,000—all of which took place too fast for human intervention to have driven them.

To identify activities that might be triggered by automated systems, the authors defined something called an ultrafast extreme event (UEE). These are cases where a stock price moved at least 10 consecutive times in the same direction, all within 1,500 milliseconds.

TSA Precheck allows passengers who have been pre-approved to keep on their shoes and belt, not remove their jackets, keep their laptops inside their cases, and not have to remove select liquids and gels from their bags.

Their IndieGoGo campaign has been a huge success, going past their $100,000 target, and is currently at around $137,000, which will allow the three person team to focus on it full time.

Except... as the team announced this morning, PayPal, for reasons known only to PayPal, has decided to freeze their funds and won't let Mailpile access the money that people donated.

"Afer 4 phone calls, the last of which I spoke to a supervisor, the understanding I have come to is, unless Mailpile provides PayPal with a detailed budgetary breakdown of how we plan to use the donations from our crowd funding campaign they will not release the block on my account for 1 year until we have shipped a 1.0 version of our product."

The 17-page document, leaked to the paper by former National Security Agency contractor Edward Snowden, gives an unprecedented breakdown of the massive amount of tax-payer dollars—which reached $52 billion in fiscal 2013—that the government pours into surveillance and other intelligence-gathering programs.

The document goes on to reveal that something called the Consolidated Cryptologic Program has received more than $10 billion annually for the past four years, and it employs about 35,000 people. It also shows that 23 percent of this year's program funding supported collection and operations, 15 percent went to processing and exploitation, and 14 percent funded analysis and production.

Microsoft chief executive Steve Ballmer is to retire from the technology giant within the next 12 months.

Shares in Microsoft, criticised for its slow response to the booming market for mobile devices, leapt 9% on the news.

We'd think this was some kind of interactive Internet mystery if we didn't know better, but in fact WikiLeaks has released about 400 gigabytes' worth of mysterious data in a series of encrypted torrent files called "insurance." And no one can open it.

But if WikiLeaks releases the keys to the public—and all the governments of the world at once—then it's possible that the war on unauthorized access to government secrets could get a lot more dangerous.
