A fascinating prototype of sensor the size of a cubic millimeter has been developed with a lot of brilliant technology inside—never mind that its specifically meant for glaucoma patients. The device takes measurements every 15 minutes and uploads the readings once a day by 400 and 900MHz frequencies. Because of the small size of its antenna it needs 47 microwatts to transmit a single bit using a pulse from a capacitor, since the built in battery only provides 40 microwatts. The capacitor repeats this process until it completes the total of 1.5Kb of data. The battery lasts for 28 days, but the system has one more trick in the form of a solar cell which charges itself over 10 hours of indoor of 1.5 hours of outdoor lightning. More

It is the second milestone release that has showed up on the Internet this month. Users of this Windows 8 software have said it features a Ribbon-based user-interface, similar to the one used in recent editions of Microsoft Office. This specific milestone build also has software for a Webcam, a new task manager, a PDF reader and an immersive browser.” “Surfacings” like this tell me that Microsoft sees the value in crowdsourced opinion gathering far more than they’re sometimes given credit for.

Verteiron writes “Cable company Mediacom recently began using deep packet inspection to redirect 404 errors, Google and Bing searches to their own, ad-laden “search engine”. Despite repeated complaints from customers, Mediacom continues this connection hijacking even after the user has opted out of the process. Months after the problem was first reported, the company seems unwilling or unable to fix it and has even experimented with injecting their own advertising into sites like Google. How does one get a company infamous for its shoddy customer service and comfortable, state-wide cable monopolies to act on an issue like this?”

Additionally, Apple said that in the next major iOS software release the cache would be encrypted on the iPhone, though a timeline for that was not provided.”
