| IDC crowns Samsung the biggest phone maker by shipments for Q1 2012 May 1st 2012, 09:07  Research firm IDC is reporting that Nokia has been dethroned as the world's biggest phone maker by Samsung. In the first quarter of the year, Samsung shipped 98.3 million mobile phones, with Nokia and Apple in second and third place. In the smartphone-only charts, the Korean company shipped 42.2 of its Android and Windows Phone handsets, while Cupertino shipped 35.1 million and Nokia shipped a paltry-by-comparison 11.9 million. Samsung, Apple and companies outside the top 5 all made big gains in the smartphone space, while Nokia, RIM and HTC all felt their numbers drop. Unsurprisingly, companies with big stakes in feature-and-dumb phone businesses suffered, with Nokia and LG losing big chunks of its market share to the big two and stalking horse ZTE, which has bested LG for fourth place. After the break, we've got the official tallies that you can pour over.

Better known as Geohot, he first achieved internet fame at the age of 17 with his announcement of a hardware unlock method for the original iPhone. From there, he moved on to even greater notoriety with a PlayStation 3 exploit that quickly attracted the ire -- and legal wrath -- of Sony. Now profiled in The New Yorker, we're given a candid and unique insight into the world of George Hotz, whereby his own admission, he wasn't motivated by an ideology so much as boredom and the desire to control a system. The freedom issues, it seems, were merely an afterthought. George Hotz is unique. We're talking about someone who was programming by age five, building video game consoles by the 5th grade and making appearances on NBC's Today at age fourteen. Like many brilliant adolescents, he experimented with drugs and rebelled against authority. Eventually, the powers that be caught up with him, and George Hotz was sued by Sony on January 11th, 2011. The lawsuit drew the attention of malicious hacker groups such as Anonymous and LulzSec, which retaliated against the company in very public ways. However unintentional, Geohot became the poster child for hacktivists and inspired a movement that quickly grew out of control -- if only more of us could be so productive with our boredom.

Fiber optics let us shoot data to and fro at top speed, but for the time being our CPUs still make their calculations using electronic transistors. Good news is, researchers from Purdue University have built an optical transistor out of silicon that can propagate logic signals -- meaning it can serve as an optical switch and push enough photons to drive two other transistors. It's constructed of a microring resonator situated next to one optical line that transmits the signal, and a second that heats the microring to change its resonant frequency. The microring then resonates at a specific frequency to interact with the light in the signal line in such a way that its output is drastically reduced and essentially shut off. Presto, an optical transistor is born. Before dreams of superfast photonic computers start dancing in your head, however, just know they won't be showing up anytime soon -- the power consumption of such transistors is far beyond their electronic counterparts due to the energy inefficient lasers that power them.
