Hasta La Gadget!

It takes a lot of energy for computing systems or data centers to patch up critical errors, but what if we devoted less power to fixing less urgent issues? That’s the basic idea behind EnerJ — a new power-saving system that could cut a chip’s energy consumption by 90 percent, simply by prioritizing critical problems over those that are less threatening. Unlike, say, liquid cooling techniques, the University of Washington’s framework focuses exclusively on the programming side of the equation and revolves around two interlocking pieces of code: one that handles crucial, precision-based tasks (e.g., password encryption), and another designed to deal with processes that can continue to function, even when facing small errors. The system’s software would separate the two codes, meaning that energy from one section of the chip would never be used to fix a major problem that the other should address, while allowing engineers to more efficiently allocate voltage to each region. The system has already cut energy usage by up to 50 percent in lab simulations, but researchers think the 90 percent threshold is well within their reach, with computer engineering professor Luis Ceze (pictured above) predicting that the system may even be able to increase battery life by a factor of ten. The team is hoping to release EnerJ as an open-source tool this summer, but for now, you can find more information in the PR after the break.

TV viewers are a famously fickle bunch, which tends to drive TV advertisers crazy. The prevalent theory remains that skipping past ads using a pesky DVR is the biggest enemy of marketers, but new research has once again contradicted that received wisdom. The IPG Media Lab in Los Angeles pulled together a representative group of 48 TV and online video viewers and asked them to sit through some programming while equipped with the usual “devices or distractions” that accompany their viewing habits. Central to the study was the measurement of time each person spent facing the screen and how engaged they were with the content. The first thing noted was that 94 percent of TV viewers and 73 percent of online video consumers used some other form of media to augment their visual entertainment. Smartphones were the most common, with 60 percent of test subjects resorting to their handset while gawking at the TV. That’s resulted in a mediocre 52 percent attention level during actual programs and 37 percent during ads. In other words, two thirds of the time, commercials are being ignored and smartphones are helping people with that heinous behavior. Ironically, fast-forwarding adverts using a DVR garnered attention levels that were 12 percent higher, mostly because people were trying to make sure they didn’t skip too far ahead. Damn, why does reality have to be all complex and stuff?

Gadgets need to be rounded up and thrown in a cell right alongside meat glue, child pageants and other notorious public enemies. The crime? Stressing people out, according to researchers at Ipsos Mendelsohn. The evidence? A survey of affluent Americans with a household income over $100,000 who moaned that their lives are more “complicated” than they were a decade ago. Damningly, the vast majority of these respondents also admitted that their lives are more “technology-infused” than a decade ago. The researchers also highlighted evidence from a separate poll of affluents, showing the growing prevalence of certain gadgets that add to the “complex calculus” of our lives: E-reader ownership has doubled over the last eight months, smartphone ownership is up to 52 per cent, and a third of affluents either own a tablet or expect to buy one soon. Sufficient proof, it seems, to send these poor devices down for life — especially if we disregard all the other things that have stressed out rich Americans over the past decade (recessions, deficits, bad TV serials) and the possibility that busier people might actually need more technology to help them cope.
