Conferences vs. Journals in Computing Research
An old joke tells of a driver, returning home from a party where he had one drink too many, who hears a warning over the radio about a car careening down the wrong side of the …DEPARTMENT: Letters to the editor
Logic of Lemmings in Compiler Innovation
I am deeply ambivalent about what I read in the contributed article "Compiler Research: The Next 50 Years" (Feb. 2009). On the one hand, its description of the field's challenges and opportunities evoke great excitement; on the …DEPARTMENT: blog@CACM

The Network Neutrality Debate Hits Europe
Differences in telecommunications regulation between the U.S. and the European Union are a key factor in viewing the debate over network neutrality legislation from a European perspective.Increasing Gender Diversity in the It Work Force
Want to increase participation of women in IT work? Change the work.The Rise, Fall, and Resurrection of Software as a Service
The commercial opportunities of software as a service are widely hyped these days and many think SaaS is the future of software. That might be true in the medium term, but the volatile history of remote …Teaching Computing to Everyone
Georgia Institute of Technology has required every undergraduate on campus to take a course in computing. Here are the lessons learned from the practice, now almost 10 years old, of creating high-demand computer science courses …Program Committee Overload in Systems
Conference program committees must adapt their review and selection process dynamics in response to evolving research cultural changes and challenges.SECTION: Practice
Security in the Browser
Users with no security training download Web browsers from the Internet without precaution, and demand that they be fast and easy to use. What can be done to make browsers secure while preserving their usability?API Design Matters
It is very easy to create a bad API and rather difficult to create a good one. Recent APIs implemented in modern programming languages make the same mistakes as their 20-year-old counterparts written in C. What can be done to …Debugging AJAX in Production
Lacking proper browser support, what steps can we take to debug production AJAX code?SECTION: Contributed articles
Spending Moore's Dividend
Multicore computers shift the burden of software performance from chip designers and to software developers. Now the computing industry is challenged to make parallel computing the mainstream method …Computing Needs Time
The passage of time is essential to ensuring the repeatability and predictability of software and networks in cyber-physical systems.SECTION: Review articles
Algorithmic Systems Biology
The convergence of computer science and biology will serve both disciplines, providing each with greater power and relevance.SECTION: Research highlights
Technical Perspective: A Chilly Sense of Security
Many systems rely on keeping a master key secret. But technological progress can undermine old assumptions.Lest We Remember: Cold-Boot Attacks on Encryption Keys
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 its contents persist sufficiently for malicious (or forensic) …Technical Perspective: Highly Concurrent Data Structures
The advent of multicore architectures has produced a Renaissance in the study of highly concurrent data structures.Scalable Synchronous Queues
In a thread-safe concurrent queue, consumers typically wait for producers to make data available. In a synchronous queue, producers similarly wait for consumers to take the data. We present two new nonblocking, contention-free …COLUMN: Last byte
Puzzled: Understanding Relationships Among Numbers
Welcome to three new challenging mathematical puzzles. Solutions to the first two will be published next month; the third is as yet (famously) unsolved. In each puzzle, the issue is how numbers interact with one another.SECTION: Virtual extension
