Seven Principles For Secure E-Voting
E-voting can be as secure and confidential as paper-based voting, as discussed in "The U.S. Should Ban Paperless Electronic Voting Machines" (Oct. 2008). However, to work properly …DEPARTMENT: CACM online
The Dot-Org Difference
One of the first things you'll notice about the new Communications Web site (cacm.acm.org) is that it has different content than the monthly magazine. A distinctive …COLUMN: News
Photography's Bright Future
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.Making Sense of Sensors
Researchers are recognizing the potential of position sensors to help them overcome the limitations of traditional user interfaces.The First Internet President
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.SIGGRAPH Debuts in Asia
ACM's premier computer graphics conference hosts its first-ever graphics event in Asia, with a more global focus.COLUMN: Viewpoints
Economic and Business Dimensions: The Extent of Globalization of Software Innovation

Technical Perspective: Tools For Information to Flow Securely and Swift-ly
Back in the old days of the Web (before 1995), Web browsers were fairly simple devices. The server's Web interface was simple enough that an auditor could at least look at it and reason about its security. Today, it's a different …Building Secure Web Applications With Automatic Partitioning
Swift is a new, principled approach to building Web applications that are secure by construction. Swift automatically partitions application code while providing assurance that the resulting placement is secure and efficient. …Technical Perspective: The Complexity of Computing Nash Equilibrium
Computer science and game theory go back to the same individual, John von Neumann, and both subjects deal with the mathematization of rational decision making. Yet, for many …The Complexity of Computing a Nash Equilibrium
Traditionally, computational problems fall into two classes: those that have a polynomial-time algorithm and those that are NP-hard. However, the concept of NP-hardness cannot be applied to the rare problems where "every instance …COLUMN: Last byte
Puzzled: Will My Algorithm Terminate?
Welcome to three new challenging mathematical puzzles. Solutions to the first two will be published next month; the third is as yet unsolved. In them all, I concentrate on algorithm termination, outlining some simple procedures …SECTION: Virtual extension
