    Navigation has long been considered an art form best practiced by experienced sailors. But today, thanks to the multitude of affordable, hand-held, Global Positioning System receivers on the market, almost anyone can be a navigational Magellan. The US Department of Defense (DOD) is at an advantage: it reserves for its own use the most accurate form of geolocation available, which puts X within a m... View full abstract»

    The rise of the so called information economy, borne along by proliferating computers, sprawling telecommunications, and the Internet, has radically transformed how people do business, govern, entertain themselves, and converse with friends and family. Private documents that in the past would have been committed to paper and hand-delivered or stowed under lock and key are now routinely created, se... View full abstract»

    A new approach to creating networks could simplify their construction end adaptation-if some kinks in the current specification can be remedied and missing features added. At the center of Jini connection technology is a lookup service, which resides on a server in a network. Its job is to act as a central market for Jini services scattered around the network, grouping similar ones together and ma... View full abstract»

  • 120000 leagues under the sea [undersea optical cables]

    In 1988, only 2% of the World's transoceanic flow of messages and data was carried by undersea cables. Satellites were the dominant carrier. Today, cables carry 80% of a much bigger, ever-growing total. The reason: bandwidth, or more accurately, channel capacity, which is a function not only of bandwidth but of noise level as well. The latest optical-fiber cables have at least 3000 times the capac... View full abstract»

  • Adding error-correcting circuitry to ASIC memory

    Thinking of putting ROM or RAM onto an application-specific IC? Then consider adding error-correction code (ECC) circuitry as well. Its presence boosts yield and reduces problems with random single-cell defects in memory arrays. Admittedly, the addition also expands chip area and impacts performance, but the payoff is almost always worth it. For instance, a memory that uses ECC will be more reliab... View full abstract»
