Compressed sensing, which draws on information theory, probability theory, and other fields, has generated a great deal of excitement with its nontraditional approach to signal processing.
The rapidly changing advertisements that appear on Web pages are often chosen by sophisticated algorithms that seek to place the best ad in the best context before the right customer.
In a world that's increasingly global and interconnected, international education is growing, changing, and evolving. More than 1.5 million students a year study at schools outside their country's borders, and the nature and types of available programs are expanding, ranging from short-term programs of eight weeks or less to master's programs with a full term abroad.
MIT's Barbara Liskov is the 55th person, and the second woman, to win the ACM A.M. Turing Award.
Tech Mainstays Promote Machines That Fix Themselves
Technology companies are embracing self-healing technology, a computing strategy that could have a major impact on the data center and the desktop. IBM uses self-healing technologies in WebSphere, DB2, the Lotus Foundations product line, and its Power servers. And Sun Microsystems has designed predictive self-healing modules that enable Solaris to self-diagnose and mitigate problems.

A Difficult, Unforgettable Idea
On the 40th anniversary of Douglas C. Engelbart's "The Mother of All Demos," computer scientists discuss the event's influence — and imagine what could have been.
Digital rights management (DRM) has emerged as a widespread tool to combat piracy. So far, however, DRM systems have proved highly inconvenient to consumers who wish to view or listen to content on multiple devices, including computers, media servers, set-top boxes, portable video and audio devices, even phones. They have also proved mostly ineffective in thwarting thieves.
ACM members have a professional duty to ensure that the public comprehends and benefits from advances in computing.
Researchers working in computational photography are using computer vision, computer graphics, and applied optics to bring a vast array of new capabilities to digital cameras.
Researchers are recognizing the potential of position sensors to help them overcome the limitations of traditional user interfaces.
Barack Obama's presidential campaign utilized the Internet and information technology unlike any previous political campaign. How politicians and the public interact will never be the same.

The Long Slow Road to a $1 Million Millennium Prize
In 2006, the journal Science named the solution to the century-old Poincaré Conjecture as its "breakthrough of the year." Three years later, the Clay Mathematics Institute, which had pledged to award $1 million to the person who solves this or any of six others of its Millennium Prize Problems, has yet to name a winner. The delay sheds light on the onerous process of vetting solutions to mathematics' toughest problems.
Climate researchers have no shortage of scientific issues on which to expend computer power. The biggest problem is choosing which one to tackle first.
