A team of researchers at  ETH Zurich  has developed a rooftop mat made of a five-millimeter-thick polymer that can absorb water when it rains. The material changes properties along with the temperature—the mat becomes hydrophobic as it warms up, and the water is expelled, extracting heat from the building in a process the researchers compare to human sweat. The idea is to cool the interior with less reliance on air conditioning. It's hard to imagine how this is possibly going to work. The basic physics and thermodynamics of the plan are sound—water can transfer heat as it evaporates. But roofs, for the past several hundred years, have been designed to shed water. Absorbing it and just holding it there against the building exterior is, in conventional building practice, the last thing you want a roof to do. Look, the team in Switzerland is surely a smart group of folks. And energy-saving revolutions in building practices are always exciting. Here are a few questions the t...

Found along the sidelines of Panasonic's CEATEC booth, the AX series Ultrabook is a foldable  hybrid that will be arriving in Japanese stores later this month. Ready to launch with Windows 8 (both standard or Pro) built-in, the Ultrabook houses a 11.6-inch touch display at the  ever-popular  1,366 x 768 resolution, although it feels a little on the thick side, and is  unmistakably Panasonic  in its styling. Connectivity options are legion, with two USB 3.0 ports on the right edge, accompanied by HDMI socket. On the other side, there's an SD card reader, ethernet, power, mic and headphone ports. The hinge seems suitably solid, and while that touchscreen isn't the most attractive we've seen on Windows 8 hardware, the keyboard felt pretty similar to existing business laptops and our fingertips had plenty of space. Otherwise, we were left to play with a Japanese iteration of Windows 8, which seemed nice and responsive in both tablet and notebook setups, althoug...

One of the major benefits that SQL Server provides is the scaling out the SQL Server Reporting Services. SQL Server Reporting Services are used as concept of hosting reports which various business processes requires. SQL Server Reporting Services does an efficient job in hosting all the reports. But the problem comes when the load starts increasing in terms of number of users accessing the reports. This may result in: 1.         Slow processing of SQL Server Reports 2.         Crashing of SQL Server Reports Server In order to overcome the above issue, SQL Server Reporting Services can be overcome through the concept of scalability. This is implemented with the help of network load balancing (NLB) and Domain Implementation. The following figure gives a clear cut picture of how to achieve the same: I n the above example, there are there servers in the NLB serving the clients through a Virtual NLB IP ...

With job postings still scarce, job security dissipating, and wages seemingly stagnant at best, many people are trying to establish some security by creating multiple streams of income. It’s a smart strategy, but if you have trouble leaving your home or primary position to  get to a second job , you’ll find yourself frustrated and stressed out. Perhaps you’re raising kids and you’re committed to not using daycare. Maybe you’re a little older and can’t commit to a full-time job. Or you might be injured or disabled, making it difficult for you to leave your home each day. Whatever your reason is, if you’re stuck at home most of the day, you've probably thought about the income you  could  be making by taking a  work-from-home job  or running your own business. Good news: There are plenty of legitimate ways to earn extra money sitting right where you are right now. Some of them involve  starting your own small business , while others...
