Many Web sites embed third-party content in frames, relying on the browser's security policy to protect against malicious content. However, frames provide insufficient...Adam Barth, Collin Jackson, John C. Mitchell From Communications of the ACM | June 2009
The web has brought exciting new functionality while simultaneously requiring new mechanisms to make it secure. We've...Andrew Myers From Communications of the ACM | June 2009
In a thread-safe concurrent queue, consumers typically wait for producers to make data available. In a synchronous queue, producers similarly wait for consumers...William N. Scherer, Doug Lea, Michael L. Scott From Communications of the ACM | May 2009
The advent of multicore architectures has produced a Renaissance in the study of highly concurrent data structures.Maurice Herlihy From Communications of the ACM | May 2009
DRAM retains its contents for several seconds after power is lost. Although DRAM becomes less reliable when it is not refreshed, it is not immediately erased, and...J. Alex Halderman, Seth D.
