DEPARTMENT: Letter from the Editors-in-Chief of CACM and JACM
Communications of the ACM has become known as the "flagship magazine of the ACM." While ACM has an impressive collection of other high-quality journals and magazines, the flagship is not leading the fleet!
DEPARTMENT: From the president
ACM has been pursuing an initiative to make computer science acceptable as a core science along with mathematics, physics, biology, and chemistry.
DEPARTMENT: Letters to the Editor
Peter J. Denning's "The Science in Computer Science" (May 2013) explored the ongoing dispute over scientific boundaries within computer science. However, the boundaries separating the sciences, and knowledge in general, have
Philip Guo offers programmers 'Opportunistic Programming' tips that typically are not shared in school.
Disk drives and solid-state drives have long served as the foundation for computer storage, but breakthroughs in molecular and DNA science could revolutionize the field.
New handheld medical diagnostic tools promise more efficient, lower-cost healthcare — but at what price?
The debate rages on about whether crowdsourcing is a win-win for workers, as well as for employers.

Considering new business models for massive open online courses.
COLUMN: Privacy and security
Attempting to use isolation as a security strategy for critical systems is unrealistic in an increasingly connected world.

Software is supposed be a part of computer science, and science demands proof.
How pair programming, peer instruction, and media computation have improved computer science education.
Censorship of information often has the opposite effect by drawing attention to the censored material.
Embracing failure to improve resilience and maximize availability.

SECTION: Research highlights
The following paper by Batson, Spielman, Srivastava, and Teng surveys one of the most important recent intellectual achievements of theoretical computer science, demonstrating that every weighted graph is close to a sparse
Graph sparsification is the approximation of an arbitrary graph by a sparse graph. We explain what it means for one graph to be a spectral approximation of another and review the development of algorithms for spectral sparsification

Each of these puzzles involves game-playing strategy. If you are sufficiently clever — and sufficiently unmotivated to work hard at being clever — you can solve them all without resorting to algebra.
