How to Teach Computer Ethics through Science Fiction
Science fiction in particular offers students a way to cultivate their capacity for moral imagination.

Multiparty Privacy in Social Media
Online privacy is not just about what you disclose about yourself, it is also about what others disclose about you.
Technical Perspective: Graphs, Betweenness Centrality, and the GPU
"Accelerating GPU Betweenness Centrality" by McLaughlin and Bader ably addresses the challenges to authors of efficient graph implementations in the important context of a computation called betweenness centrality.
Accelerating GPU Betweenness Centrality
We present a hybrid GPU implementation that provides good performance on graphs of arbitrary structure rather than just scale-free graphs as was done previously.
Regulating Automated Decision Making
A group assembled by Informatics Europe and the policy committee of the ACM Europe Council produced a report entitled "When Computers Decide" that makes 10 recommendations to policy leaders regarding automated decision making.
A primary topic of consideration at a recent workshop on cybersecurity was how to preserve the freedom and openness of the Internet while protecting against the harmful behaviors that have emerged in this global medium. That this is a significant challenge cannot be overstated.
Assessing Responsibility for Program Output
We lack an easy way to indicate that algorithms do not make decisions and are not biased; programmers do, and are.
How liable should programmers be for the quality of their software?
Discussing Empirical Answers to Questions of Software Engineering
Focusing on what helps software developers.
A Software Architect Is the Person You Blame
How efficient is your current software project, and could it potentially benefit from the addition of a software architect?
Digital Nudging: Guiding Online User Choices through Interface Design
Designers can create designs that nudge users toward the most desirable option.
Making Machine Learning Robust Against Adversarial Inputs
Such inputs distort how machine-learning-based systems are able to function in the world as it is.
Always Measure One Level Deeper
Performance measurements often go wrong, reporting surface-level results that are more marketing than science.
The ABCs of Effectiveness in The Digital Society
Digital effectiveness is not the same as mastering the ICTs, rather it is the art of using them in a purposeful, healthy way.
Majority Is Not Enough: Bitcoin Mining Is Vulnerable
We propose a practical modification to the Bitcoin protocol that protects Bitcoin in the general case.
Technical Perspective: The Rewards of Selfish Mining
"Majority Is Not Enough: Bitcoin Mining Is Vulnerable," by Eyal and Sirer, questions the 2009 Bitcoin white paper's implicit assumption of perfect information—that all miners have the same view of the blockchain.
Research for Practice: Toward a Network of Connected Things
Expert-curated guides to the best of CS research.
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.
