"Uber knows when your phone battery is running low because its app collects that information in order to switch into power-saving mode. But Chen swears Uber would never use that knowledge to gouge you out of more money. "We absolutely don't use that to kind of like push you a higher surge price, but it's an interesting kind of psychological fact of human behavior," Chen said. Uber's surge pricing uses a proprietary algorithm that accounts for how many users are hailing rides in an area at a given time. Customers are apparently less willing to believe that when the multiplier is a round number like 2.0 or 3.0, which seems more like it could have been arbitrarily made up by a human."

"How can you sort the books quickly? Chand John shows how, shedding light on how algorithms help librarians and search engines speedily sort information."

"But when you dive into the code of Meitu, that's where things get interesting. Security researchers have jumped in to assess the photo editing app and found that it was indeed collecting information, including a phone's IMEI number (a handset's unique ID number), and sending it back to remote servers:"

"This algorithm uses a recurrent neural network to predict sound features from videos and then produces a waveform from these features with an example-based synthesis procedure. We show that the sounds predicted by our model are realistic enough to fool participants in a "real or fake" psychophysical experiment, and that they convey significant information about material properties and physical interactions."

"Security experts who looked at the app, known as ByLock, at the request of Reuters said it appeared to be the work of amateur software developers and had left important information about its users unencrypted."

"There aren't many exit nodes out there. Many people fear that running an exit node will put them in police crosshairs if it gets used in the commission of a crime. For the record, Boing Boing runs a very high-capacity exit node, and though we've received multiple contacts from US law enforcement, we've just explained that this is a Tor node that runs with logging switched off, and thus we have no information that'll be relevant to any investigations, and the officers involved have thanked us and gone away without further trouble. "

""No-limit Texas Hold'em is a game of incomplete information where the AI must infer a human player's intentions and then act in ways that incorporate both the direct odds of winning and bluffing behaviour to try to fool the other player." The designers said their computer didn't "bluff" the human players. But by learning from its mistakes and practising its moves at night between games, the AI was working out how to defeat its human opponents."

"Drug and insurance companies will from later this year be able to buy information on patients - including mental health conditions and diseases such as cancer, as well as smoking and drinking habits - once a single English database of medical data has been created."

"User information, including passwords, email addresses, usernames and geolocation data, was unencrypted - making it readily accessible to anyone who plugs the handset into a PC, according to a report detailing the vulnerability."

"Intentions aside, the app seems to cross some pretty serious privacy boundaries. Generally speaking, people like to choose who they identify themselves to, and having your online information freely available to anyone who sees you in public seems an uncomfortable prospect. Google seems to think so, too; the Web giant does not currently allow facial recognition apps on the MyGlass app store. "

"The information sharing is on an opt-out basis, so if you don't want your "clinical records, mental health consultations, drug addiction rehabilitation details, dsexual health clinic attendance and abortion procedures" shared, along with your "GP records, HS numbers, post-codes, gender, date of birth," you need to contact your doctor and opt out of the process. "

"It's an interesting wrinkle on the problem of information-leakage, and implies that future privacy-filters will have to scrub photos of reflective surfaces (especially eyes) of identifying faces before they're posted. "

"But if MH370 had been fitted with technology that made use of the cloud it may never have been lost in the first place. Instead of relying on the combination of GPS, primary and secondary radar, and aircraft communications addressing and reporting systems (ACARS) to keep track of planes, we should be making sure they send regular flight information to the data centers in the cloud."

"Government agencies around the world demanded access to the information of over 38,000 Facebook users in the first half of this year, and more than half the orders came from the United States, the company said on Tuesday."

"Taken as a whole, the information Google collects about users is shockingly complete. The company can mine your emails and Drive documents, track your browsing history, track the videos you watch on YouTube, obtain your WiFi passwords and much more."

"The transparency report is in its third year, but it hasn't prevented attacks from advocates such as Edward Snowden, who called the company "hostile to privacy". "Dropbox is a targeted you know wannabe PRISM partner," he told the Guardian in July 2014. "They just put … Condoleezza Rice on their board … who is probably the most anti-privacy official you can imagine.""

"Freedom of information website WhatDoTheyKnow.com, which automates FOI requests and publishes responses, says it has recorded 154 accidental data leaks made by councils, government departments, police, the NHS and other public bodies since 2009. This amounts to confidential data being wrongly released on average once every fortnight."

"One of the most widely used tools for monitoring and restricting pupils' internet use in UK schools has a serious security flaw which could leave hundreds of thousands of children's personal information exposed to hackers, a researcher has warned."

"The survey found that more than half of Americans say they do not want to lose control over their information but also believe this loss of control has already happened. Turow argues that marketers misrepresent Americans' behaviors by categorizing their acceptance of company discounts in exchange for personal data as rational acceptance of "tradeoffs."
