Looks likely that president elect Obama will support elimination of Daylight savings time in the US. This op-ed piece in the New York times talks about how DST does not link to energy conservation as once thought. The one thing it WOULD make easier is global collaboration - Google Cal doesn't convert to dST until AFTER it happens and we all missed a meeting.
On this page you will see how in photoshop and other designers have come together to make a device that will convert you picture to the right size on the other website if you move it and so it won't be blurry.
Schools and nonprofits need to understand their place on the web and the importance of building followers on Facebook as part of their marketing/ pr strategy.
For designers of isolated systems, rapid advances in digital isolation technology are yielding new capabilities that greatly simplify their job. Examples include integrated, isolated power and truly bidirectional isolation channels that can reduce system costs and save circuit-board real estate. These advances are fueled by a shift away from LED-based optocouplers toward newer isolator technologies that are compatible with standard foundry CMOS processes. They enable integrated circuitry to be packaged with chip-scale microtransformers, thus fitting more functionality into a single package.
This article discusses two kinds of devices that embody these advances. In the first example, isolated power, chip-scale microtransformers are complemented by switches, rectifiers, and regulators to produce an isolated, regulated dc-to-dc converter; when integrated with isolated data channels it provides a complete isolation solution. In the second example, bidirectional isolation, integrating the requisite buffers and drivers creates an isolator that has truly bidirectional isolation channels without the need for external signal conditioning.
