On April 20, a NASA rocket will lift off from Vandenburg Air Force Base carrying one of the most remarkable physics experiments ever attempted. Gravity Probe B will try to answer questions raised by Einstein's General Theory of Relativity, proposed in the early years of the 20th century. Whether Gra...
James Van Dyke had a hunch last year that the commonly held belief that the Internet was causing an increase in identity theft and credit card fraud was not valid. Extensive research he conducted debunks many of the myths about the correlation between online activity and ID theft. Contrary to popula...
Because of his background in assembly-level programming and low-level C coding on machines with slow CPUs and very little RAM, David Wren, PassMark Software's founder, had a strong interest in coding efficiency and computer performance. It was from this interest that PassMark's benchmark application...
Those wanting to represent the Internet graphically to a lay audience are fond of animations showing a spinning Earth criss-crossed by a network of buzzing, vibrating lines. Lift those animations up from the planet a bit, and you get a picture of what space someday could become -- a place where comm...
The 1990s witnessed the adoption of IT systems designed to streamline business processes through electronic automation. The introduction of these systems has challenged enterprises with how to integrate and maintain an increasing number of distributed networks and platforms. The challenge of managin...
New growth in scorched earth might be the best metaphor to describe the state of the high-end router market at present. When the Internet was booming, a bevy of startup suppliers rushed to build the top-of-the-line network devices called core routers. It was thought that products operating at gigabi...
I spend a lot of time listening to lots of folks complain that they don't have a choice, that big, bad Microsoft has come in and made their lives a living hell and that someone should do something about it. If you are one of those folks, today is your lucky day. I'm going to start telling you how to...
Internet security experts are divided on the source and purpose of computer viruses and worms like Blaster and SoBig. But some government agencies are investigating a possible connection between the increasing spread of infected computers and organized crime. Recent trends are leading many experts t...
Windows is often the whipping boy when it comes to server platforms. But many in the industry now admit that Windows Server 2003 offers some significant breakthroughs over earlier versions of Microsoft's server software -- a change that could help Microsoft compete more effectively against Unix and ...
Computer hobbyists for years have tweaked their computers' innards to squeeze out extra bits of performance. Known as overclocking, the practice has long been a holy grail to users who demand maximum performance from their systems. But overclocking a system poses hazards to the hardware, making the ...
You are walking past a coffee shop one morning, your mobile phone beeps, and up pops a coupon for a free croissant. You are driving on the highway when your computer screen displays a message telling you that an accident has occurred 10 miles up the road, so you take an alternate route. Zealous vend...
Biometric security devices -- which authenticate a person's identity on the basis of physical characteristics, such as a fingerprint -- have been available in one form or another for 30 years. But biometrics technology for computer security might never achieve widespread use because of the predomina...
Only 15 years ago, we watched in amazement while the rusty iron curtain collapsed and the formerly communist countries of Eastern Europe embarked on new lives in the global market. For most of us, this neglected region stretching from the Baltic to the Balkans then retreated to the fringes of our at...
The other day I was asked what the odds were that SCO would win against IBM. On the basis of how the two parties were behaving, I offered a range of between 55 and 65 percent. One of the strongest indications I have that SCO might win is that several of the financial analyst groups who work with me,...
