Facebook Messenger sends 'creepily' precise location data, as revealed by Marauders Map Chrome extension

Facebook sends out such precise data to people you chat with that your location can be tracked to individual streets, a new Chrome extension shows.

Every time a person sends a Facebook message from a phone, it sends out their location to the person chatting with them. The extensions scrapes all of that data and overlays it on a map, meaning that a precise chart of people’s movements can be done using those conversations.

The creator of the extension, Aran Khanna, said that he had made it to demonstrate the creepiness of the information that people might be unwittingly sharing.

Some of the data sent out makes it possible to pinpoint locations to less than a meter, he said, and that can be used to figure out people’s regular schedule or to spy on them. Khanna points out that it doesn’t take many messages to work out people’s habits, especially if a number of people collude to share their data.

Android M unveiled at Google I/O: 6 Cool new ways your Android just got better

Google has announced the latest version of Android, called Android M, at its annual Google I/O developer conference on May 28. The pre-release version for developers will debut today and the full version will be made available later this year.

According to Sundar Pichai, the Android M operating system will concentrate more on improving the stability and usability of the platform. There will be a lot more emphasis on the quality of the platform rather than a radically new look.

Just like last year’s Google I/O where Android L was teased, the Android M platform hasn’t yet got a codename. Also, the preview will only be available for Google Nexus 5, 6, 9 and Nexus Player.

Speaking at Google I/O, David Burke, the vice president of engineering at Google, said that Google is planning to integrate a lot of the features that they have seen device makers add on to Android. According to him, with Android M there are six major areas where Google is focussing.

Microsoft developing Cortana app for iOS, Android

Microsoft is bringing Cortana to iOS and Android smartphones, extending the voice-controlled personal assistant to platforms beyond Windows 10 and Windows Phone.

Overkill - America’s Epidemic of Unnecessary Care

It was lunchtime before my afternoon surgery clinic, which meant that I was at my desk, eating a ham-and-cheese sandwich and clicking through medical articles. Among those which caught my eye: a British case report on the first 3-D-printed hip implanted in a human being, a Canadian analysis of the rising volume of emergency-room visits by children who have ingested magnets, and a Colorado study finding that the percentage of fatal motor-vehicle accidents involving marijuana had doubled since its commercial distribution became legal. The one that got me thinking, however, was a study of more than a million Medicare patients. It suggested that a huge proportion had received care that was simply a waste.

The researchers called it “low-value care.” But, really, it was no-value care. They studied how often people received one of twenty-six tests or treatments that scientific and professional organizations have consistently determined to have no benefit or to be outright harmful. Their list included doing an EEG for an uncomplicated headache (EEGs are for diagnosing seizure disorders, not headaches), or doing a CT or MRI scan for low-back pain in patients without any signs of a neurological problem (studies consistently show that scanning such patients adds nothing except cost), or putting a coronary-artery stent in patients with stable cardiac disease (the likelihood of a heart attack or death after five years is unaffected by the stent). In just a single year, the researchers reported, twenty-five to forty-two per cent of Medicare patients received at least one of the twenty-six useless tests and treatments.
