Turing Award recipients Shafi Goldwasser and Silvio Micali talk about proofs, probability, and poker.
Rules of thumb stated as numerical rules are enticing, but many are folk theorems that may not apply in your critical situation.
Shafi Goldwasser and Silvio Micali laid the foundations for modern cryptography, with contributions including interactive and zero-knowledge proofs.
Learning from the Past to Face the Risks of Today
The Space Shuttle software program can provide guidance to today's projects.
There Is No Getting Around It: You Are Building a Distributed System
Building a distributed system requires a methodical approach to requirements.
Discrimination in Online Ad Delivery
Google ads, black names and white names, racial discrimination, and click advertising.
Flash memory has come a long way and it is time for software to catch up.
The NVIDIA OptiX ray tracing engine builds on the key observation that most ray tracing algorithms can be implemented using a small set of programmable operations.
Technical Perspective: The Ray-Tracing Engine That Could
It has been an open question whether it is possible to build GPU-targeted high-performance software systems that are themselves programmable. "GPU Ray Tracing" shows how to achieve both programmability and high performance in such a system.
Max Newman: Forgotten Man of Early British Computing
Reflections on a significant, yet often overlooked, computing pioneer.
Moving from Petaflops to Petadata
The race to build ever-faster supercomputers is on, with more contenders than ever before. However, the current goals set for this race may not lead to the fastest computation for particular applications.
Researchers are making headway with one of quantum computing's major theoretical problems: multi-prover interactive proofs.
Catastrophism and reliance on dubious studies have no place in serious discussions of software engineering.
Developing Tools and Resources For Those in Practice
To many younger software practitioners, ACM remains incorrectly stereotyped as an organization for researchers or professors but not targeted to individuals who design, implement, deliver, and deploy software for a living. The ACM Practitioner Board aims to change that.
Scientists at the Blue Brain Project are using supercomputers to simulate neural connections in a 3-D model of a slice of mammalian brain.
Offline Management in Virtualized Environments
How to run virtual machines together with physical machines, especially when sharing computational resources.
Why Computer Talents Become Computer Hackers
Start with talent and skills driven by curiosity and hormones, constrained only by moral values and judgment.

Q&A: The Power of Distribution
Nancy Lynch talks about achieving consensus, developing algorithms, and mimicking biology in distributed systems.
Shape the Future of Computing
ACM encourages its members to take a direct hand in shaping the future of the association. There are more ways than ever to get involved.
Get InvolvedCommunications of the ACM (CACM) is now a fully Open Access publication.
By opening CACM to the world, we hope to increase engagement among the broader computer science community and encourage non-members to discover the rich resources ACM has to offer.
