Since late last year, members of the U.S. Congress have introduced no less than 34 different bills dealing with information security and Internet policy. Many of these bills are well-meaning, such as the House resolution calling upon Vietnam to “release imprisoned bloggers and respect Internet freedom” — even if the bill applies no penalties and, more importantly, appropriates no money. But the more significant “cyber” bills are the ones dealing with the security of the Internet. Since April 1, 2008, when Sens. Jay Rockefeller and Olympia Snowe introduced a particularly mammoth piece of cyber legislation, Congress has worked diligently in […]

As the senior managing director of a technology firm that employs algorithms in their most complex forms, I spend a lot of time trying to explain, via nature-centric analogies, how these formulae work. The most cutting-edge algorithms are known as “genetic algorithms,” because they self-adapt their “recipes” through interactions with a wider environment of stimuli, thereby approximating evolutionary responses found in nature. The hardest part about explaining that to people comes from overcoming their bias toward unnatural silicon solutions, as opposed to the carbon-based pathways of discovery and adaptation through failure that define our human existence. Oddly enough, people tend […]

The new space craft’s launch occurred without much fanfare. On April 22, the U.S. Air Force’s X-37B prototype roared into orbit atop a rocket launched from Cape Canaveral in Florida. Some 15 years in development, the X-37’s technology, performance and purpose all are cloaked in mystery. Two months after the unmanned vehicle’s launch, it is still in orbit, performing its unspecified tasks behind the military’s veil of silence and ambiguity. That has caused concern among potential rivals of the U.S. The X-37, which looks like a quarter-scale Space Shuttle, is just 29 feet long from nose to tail and boasts […]

American culture has long had a fascination with outer space. President John F. Kennedy described it as “this new ocean,” and words like “destiny” and “frontier” are frequently used to characterize America’s relationship to it. Hollywood and the media often approach it with a sense of wonder, humility, and even a bit of fear. From the opening strains of “2001: A Space Odyssey” to the aliens from “Avatar,” space remains a source of mystery. This cultural phenomenon may be a remnant of the first two-thirds of the 20th century, when in the span of a single lifetime, it was possible […]

The past year has been a pivotal period for one of the world’s most important strategic industries. In 2009 and early 2010, the military aerospace industry marked key turning points: For the first time, the U.S. Air Force — the world’s most important aerospace customer — bought more unmanned aircraft than manned aircraft. In the same time-span, the Air Force refused to extend production of its exclusive, world-beating F-22 fighter beyond the 187 units it has already ordered, instead opting to develop the smaller, potentially cheaper-per-unit and exportable F-35 Joint Strike Fighter. Following that decision, revelations surfaced in early 2010 […]

After half a century, the revolution in computer technology continues to rapidly transform the world about us. For reasons that are fundamentally economic, the atomic building blocks on which that revolution is based are semiconductor electronic components — chips. It has been estimated that technological improvements in semiconductors accounted for 40 percent to 60 percent of the price-performance improvement in computers in the late 1990s. Those rapid declines in computer prices in turn led to much wider usage of computers and significant improvement in U.S. productivity growth during the same period. The first electronic digital computers used during World War […]
