Should researchers focus on designing new network architectures or improving the current Internet?
Information technology has the potential to radically transform health care. Why has progress been so slow?
Error-detection and correction features are only as good as our ability to test them.
Improving the performance of complex software is difficult, but understanding some fundamental principles can make it easier.
SECTION: Contributed articles
Computing research ages more slowly than research in other scientific disciplines, supporting the call for parity in funding.
The same component isolation that made it effective for large distributed telecom systems makes it effective for multicore CPUs and networked applications.
SECTION: Review articles
A call for the perfect marriage between classical performance evaluation and state-of-the-art verification techniques.
SECTION: Research highlights
Government agencies worldwide release statistical information about population, education, and health, crime, and economic activities. In the U.S., protecting this data
Privacy Integrated Queries (PINQ) is an extensible data analysis platform designed to provide unconditional privacy guarantees for the records of the underlying data sets. PINQ's analysis language and its implementation provide
It takes little imagination to come up with a wealth of problems in scheduling and planning that can be expressed as Constraint Satisfaction Problems (CSPs). It's no surprise
In a constraint satisfaction problem (CSP) the goal is to find an assignment of a given set of variables subject to specified constraints. A global cardinality constraint is an additional requirement that prescribes how many

It's amazing how little we know about good old plane geometry. Last month (August 2010, p. 128) we posted a trio of brainteasers, including one as yet unsolved, concerning figures on a plane. Here, we offer solutions to two of
In a world of technology and fear, the public gets to know what it wants to know . . . and more than it can possibly digest.
