Scientists are simulating biological organisms and replicating evolution in the lab. How far can they expand the boundaries of virtual life?
How digital media could be authenticated, from computational, legal, and ethical points of view.
Taking stock of progress toward a computing profession since this column started in 2001.
Bitcoin’s Underlying Incentives
The unseen economic forces that govern the Bitcoin protocol.
Evolution Toward Soft(er) Products
As software becomes a larger part of all products, traditional (hardware) manufacturers are becoming, in essence, software companies.
The Wisdom of Older Technology (Non)Users
Older adults consistently reject digital technology even when designed to be accessible and trustworthy.
A Programmable Programming Language
As the software industry enters the era of language-oriented programming, it needs programmable programming languages.
A Declaration of the Dependence of Cyberspace
Just as you cannot separate the mind and the body, you cannot separate cyberspace and physical space. It is time to accept this dependence and act accordingly.
If intelligent robots take on a larger role in our society, what basis will humans have for trusting them?
The Internet as we know it today has driven the barrier to the generation and sharing of information to nearly zero. But there are consequences of the reduced threshold for access to the Internet.
Technical Perspective: On Heartbleed: A Hard Beginnyng Makth a Good Endyng
When a serious security vulnerability is discovered in the SSL/TLS protocol, one would naturally expect a rapid response. "Analysis of SSL Certificate Reissues and Revocations in the Wake of Heartbleed," by Zhang et al., paints a very different picture in the context of the famous Heartbleed vulnerability.
Time-Inconsistent Planning: A Computational Problem in Behavioral Economics
We propose a graph-theoretic model of tasks and goals, in which dependencies among actions are represented by a directed graph, and a time-inconsistent agent constructs a path through this graph.
Technical Perspective: A Graph-Theoretic Framework Traces Task Planning
In "Time-Inconsistent Planning: A Computational Problem in Behavioral Economics," Kleinberg and Oren describe a graph-theoretic framework for task planning with quasi-hyperbolic discounting.
Analysis of SSL Certificate Reissues and Revocations in the Wake of Heartbleed
We use Heartbleed, a widespread OpenSSL vulnerability from 2014, as a natural experiment to determine whether administrators are properly managing their X.509 certificates.
The developer of convolutional neural networks looks at their impact, today and in the long run.
Can Neuroevolution Change Machine Learning?
Neuroevolution borrows techniques from natural evolution to push the boundaries of machine learning.
Did We Just Replace the ‘Knowledge Bottleneck’ With a ‘Data Bottleneck’?
In practice, it seems that avoiding the knowledge acquisition bottleneck has not resulted in any net gain.
Reacting to the U.S. Nuclear Posture Review, which now tries to extend nuclear deterrence to cyberspace.
The Increasing Familiarity of Cryptocurrencies
More and more businesses are accepting cryptocurrencies as payment; here's why.
A Comprehensive Self-Driving Car Test
Every few years, I have to pass a test from the Department of Motor Vehicles to drive my car. Shouldn't a self-driving car be required to do the same thing?
Protecting the Power Grid, and Finding Bias in Student Evaluations
The Communications Web site, http://cacm.acm.org, features more than a dozen bloggers in the BLOG@CACM community. In each issue of Communications, we'll publish selected posts or excerpts.twitterFollow us on Twitter at http://twitter.com/blogCACMhttp://cacm.acm.org/blogs/blog-cacmJohn Arquilla considers the growth of cyberattacks on infrastructure, while Mark Guzdial wonders how beginning computer science students can possibly evaluate their teachers fairly.
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.
