Apple says its Tencent-powered Safe Browsing system isn't sending URLs back to China

Responding to concerns that its Safe Browsing anti-malware partnership with Tencent may share users' IP addresses and browsing history with the Chinese firm, Apple has said that “the actual URL of a website you visit is never shared with a safe browsing provider and the feature can be turned off” (The Register).

Safe Browsing systems like Tencent and Google's use partial hashes to identify malicious sites, so your online history is reasonably secure, assuming everything is operated in good faith. However, Apple did not address the potential privacy implications of user IP addresses being shared with Tencent, at a time when Chinese state surveillance and Apple's perceived cooperation with it are very much in the news.

Uber makes 350 more redundancies

The Vanmoof Electrified X2 is the ultimate e-bike

WIRED tested the Dutch brand Vanmoof’s Electrified X2 bicycle over three weeks on a varied 20km daily commute from Stoke Newington in London to the WIRED offices in the West End. The route took in heavy traffic, a variety of hills and residential streets (WIRED).

With a power assist that is activated by just turning the cranks, (without a torque sensor) the X2 can comfortably maintain a 17-19mph top speed (even uphill) without the rider applying any significant pressure to the pedals or raising their heart rate, making for a smooth and unsweaty commute, even if it is ‘cheating’
