Twenty-five years ago, on March 12, 1989, Tim Berners-Lee proposed "a universal linked information system" to help itinerant academics from across the globe run a complicated particle accelerator. Boy, did the World Wide Web ever exceed those initial expectations. Berners-Lee aimed to help the CERN facility in Switzerland, but he called for a system that worked much more broadly. And spread it did, fostered by the then-novel idea of hyperlinking that let people feed vast amounts of information into the Web, giving it a location and a way of finding it later. "The result should be sufficiently attractive to use that the information it contained would grow past a critical threshold, so that the usefulness the scheme would in turn encourage its increased use," Berners-Lee wrote. That positive feedback loop caught on, and Berners-Lee spawned a global technological and social force. He also founded the World Wide Web Consortium (W3C) to help oversee the Web's technology. Even with … [Read more...] about Tim Berners-Lee: 25 years on, the Web still needs work (Q&A)

Leveraging New Communication Tools Need to get in touch with someone who's not answering the phone? Using unified communications could get you connected through other available means. Christopher Robbins/Photodisc/Thinkstock To understand how communications tools can help businesses cut costs, let's take a closer look at a class of products and services commonly referred to as unified communications (or UC). Offered by various companies, UC systems typically involve a whole host of communications solutions that save time -- one of the most basic approaches a company can adopt to save money -- by connecting employees, clients and databases in more meaningful ways. Plus, with the advent of 3G and 4G networks, this can even apply to mobile participants. Based on the specific UC setup's products and services, it can generally perform a number of tasks. For starters, it can halt endless rounds of time-wasting phone tag: Employees can check the statuses of their co-workers and … [Read more...] about How can new communications tools cut costs?
Making International Calls from a Cell Phone International calls can be made from cell phones depending on your service provider. Photographer: Alexsander Bochenok | Agency: Dreamstime Making an international call from a cell phone is the most expensive calling option, but it's not as difficult as it sounds. Many cellular services are available for international calling. For example, if your cell phone service provider is Verizon Wireless you'll pay 49 cents a minute to call Mexico, or $1.49 a minute to call France [source: Verizon Wireless]. Companies like Verizon do offer international calling plans that provide discounted rates for an extra monthly fee. Similar to making international calls from a landline, you can get better rates by buying international calling cards that work with cell phones. Just dial a local access number, enter the PIN on the card and dial the number following the standard international format. International travelers who try to use their U.S. … [Read more...] about How to Make International Calls

That same month, a four-year-old boy helped save his mother's life when she started having an epileptic seizure, and a two-year-old beagle called for help when her person succumbed to a diabetic seizure - all by dialing nine, one and one on a telephone keypad (in the Beagle's case, she only pushed speed-dial number "9" and left the phone off the hook). These types of cases are an everyday occurrence at any 9-1-1 Public Safety Answering Point (PSAP) in the United States. Okay, the beagle thing was pretty rare, but still not unheard of. As of 2006, 99 percent of the U.S. population has 9-1-1 service. There are 200 million 9-1-1 calls per year in the United States, and 9-1-1 call-takers encounter a mind-boggling array of emergencies in their line of work. They must be prepared for almost anything. One operator in … [Read more...] about How 9-1-1 Works
iRobot's ConnectR. Like a curling stone, except smarter. See more pictures of robots. Photo courtesy iRobot iRobot, a company founded by Massachusetts Institute of Technology roboticists, recently revealed the revolutionary ConnectR. Its newest robot looks a little bit like a curling stone, with a reddish-orange color reminiscent of the set of "2001: A Space Odyssey." The company has had success with its other robots, including the Roomba, a robot vacuum cleaner; the Scooba, a robot mop; and the Verro, which cleans pools. A gutter-cleaning robot, the Looj, was revealed by the company the same day as the ConnectR. Robot Image Gallery But the ConnectR is different from its siblings. Rather than to serve a strictly utilitarian function like cleaning floors, it was created for social purposes. As a virtual presence, the household bot is meant to keep far-off relatives and late-working parents connected to their families. The robot is based on the Roomba design and features two … [Read more...] about How ConnectR Works
