Microgrid Keeps the Power Local, Cheap, and Reliable
ties together power from fuel cells, solar panels, wind turbines, and diesel generators ..... to form a microgrid that can operate independently of large, centralized power plants. ..... an emerging smart-grid technology that's providing a cleaner, more reliable, and, in some parts of the country, significantly cheaper alternative to the conventional grid. ..... special software and power electronics to integrate multiple sources of power and energy storage to provide electricity around the clock, even when the sun isn't shining or regulations limit the use of diesel generators ..... If the utility experiences a large spike in demand, the microgrid can respond by selling excess power to the utility. .... The first customers for microgrids are businesses and organizations that can't afford even short power outages—such as jails, hospitals, data centers, and military bases—or remote areas that don't have access to the grid.
This philosophy has to be applied to the growth and consumption of food. Not all of it. But at least some parts of it. People should have the option.

The Latest Threat: A Virus Made Just for You
a refinement to the technique could make automated analysis of malware nearly impossible ..... The makers of antivirus software regularly collect samples of malware and then use automated analysis to generate a collection of identifying characteristics, commonly called a signature. .... polymorphism—a technique for changing programs each time they are copied to a new machine ..... The database of malware maintained by Symantec includes about 19 million signatures. In its annual Internet Security Threat Report released earlier this year, Symantec stated that its automated analysis systems analyzed 403 million unique variants of malicious programs in 2011, a 41 percent increase from the 286 million analyzed in 2010. Without automation, this task would be much harder.
The devil has time on his hands, looks like. The fight between good and evil continues. This reminds me of This World dictators beating the protesters in their use of information technology. Like in Burma several years back the authorities encouraged protesters to go out in the streets and take pictures and upload them online. Then they coldly downloaded them to identify and punish individual protesters.

An Indian Software Company Brings Jobs Back to the U.S.
Infosys announced today that it will open a new U.S. software development center and hire 2,000 workers in the U.S. this year as it expands operations here. The new center in Milwaukee will help serve a five-year IT contract with motorcycle manufacturer Harley Davidson.
2,000 jobs getting created making headlines: that is not a good sign.

Software Detects Motion that the Human Eye Can't See
for example, measure someone's pulse by shooting a video of him and capturing the way blood is flowing across his face...... the primary application will be for remote medical diagnostics, but it could be used to detect any small motion, so that it might let, for example, structural engineers measure the way wind makes a building sway or deform slightly..... it can just take standard video, from just about any device, and then process it in a way that finds this hidden information in the signal
This can be of great help to remote medicine.
