New York City may be a lot of things — the city that never sleeps, the Big Apple, home of Ground Zero — but its future is as a data platform, says the city’s newly-appointed chief digital officer, Rachel Sterne.

Sony said it discovered that between 17 and 19 April an “illegal and unauthorised person” got access to people’s names, addresses, email address, birthdates, usernames, passwords, logins, security questions and more. Children with accounts established by their parents also may have had their data exposed, according to Sony, which put the warning on its US PlayStation blog – although the warning about the compromise might not be immediately visible to passing readers. The company is also emailing people who might be affected. The intrusion is potentially one of the biggest ever into a store of credit cards. Sony’s PSN is one of the world’s biggest holders of credit cards, though not as large as Amazon, eBay, PayPal or Apple’s iTunes, which each hold more than 100m accounts. The previous largest hacking attacks were on Heartland Payment Systems in January 2009, when up to 100m US credit and debit card details were stolen, and TK Maxx in March 2007, when up to 46m credit card details were stolen.

It is easy to see how Roadify could be useful. But it is the kind of service that gets better as more people sign up, and it has not reached critical mass. It is not uncommon to click on, say, the E train at Queens Plaza, only to find an update saying the station is crowded — from six hours earlier. There is also some development work to be done: More than 20 bus lines have yet to be entered into the database, meaning that if you live in many parts of Queens, you’re out of luck. And the subway information is arranged by line, not by station. Trying to decide which train to take from Times Square? You have to check each line individually. Roadify is also largely nonfunctional underground, a serious shortcoming for something you want to use on the subway.

Why is my iPhone logging my location? The iPhone is not logging your location. Rather, it’s maintaining a database of Wi-Fi hotspots and cell towers around your current location, some of which may be located more than one hundred miles away from your iPhone, to help your iPhone rapidly and accurately calculate its location when requested.

But critics say online education is really driven by a desire to spend less on teachers and buildings, especially as state and local budget crises force deep cuts to education. They note that there is no sound research showing that online courses at the K-12 level are comparable to face-to-face learning.
