In the modern Web economy, hyperlinks have already attained monetary value as incoming links to a Web site can increase its visibility on major search engines. Thus links can be viewed as investment instruments that can be the subject of an exchange process.

In this study we build a simple model performed by rational agents, whereby links can be bought and sold. Through simulation we achieve consistent economic behaviour of the artificial Web community and provide analysis of its micro– and macro–level parameters.

Look ahead, to a near-future world dominated by embedded computing. Immeasurable resources are deployed everywhere, some with computation for the taking, others hard at work for the users that deployed them.

What kinds of problems arise in this environment?

In a world where engineering plays an increasingly important role, one wonders about the exact nature of the engineering experience in our time.

His transparent plastic iMac, the neat iPod, the iBook, the G4 Cube and the Titanium PowerBook are icons. They single-handedly remind us of the power of elegant, emotional design.

Friends say the roots of his success lie in his lateral thinking -- finding the true appeal of an object, often ignoring the traditional approach to design.

The iPod is like a cigarette pack for those addicted to music instead of tobacco.

This six-part series is the product of six months of reporting, encompassing 130 interviews with accident investigators, scientists and NASA employees across the United States. Staff writer Robert Lee Hotz reviewed dozens of government reports and public hearing transcripts spanning the quarter-century of the space shuttle program. He met at length with members of the Columbia Accident Investigation Board. Hotz covered the 1986 Challenger accident and has reported on other manned spaceflight issues for 20 years.

When the independent Columbia Accident Investigation Board arrived at the hangar, NASA had already arranged the wreckage to suit itself and launched its own forensic analysis.

The rivalry was immediate.

On occasion, board investigators and NASA experts found themselves in shouting matches over the best way to proceed.

It was implicitly an argument over how history would judge what happened.

"In this engaging book, social critic Laura Gurak looks past the boxes and wires of the Internet to explore the human side of the digital revolution."

New technologies and services have created explosive demand for radio spectrum. But spectrum is a finite natural resource, and under our current rules, demand is outstripping supply.

Fortunately, the same technologies that create exploding demand can provide the solution to this problem, by letting more devices use spectrum than is now possible. More intensive use of spectrum would meet existing and potential demand and could be the basis for unprecedented economic growth.
