Simpifying Machine-based Touch Sensing
A three-dimensionally-printed nervous system could allow robots to perceive touch the way we do.
The foundational work of the first AI for Good Summit allows the AI community to work together to create an infrastructure for responsible communication, development, and trust.
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.
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.
Many applications are surfacing for neural network systems, including reliable identification of diseases (for example, diabetic retinopathy, cancerous cells), situational awareness for self-driving cars, and a raft of other hard recognition and optimization problems.
How the Hippies Destroyed the Internet
Communism is the most famous 20th-century attempt to build market-free economies. It required coercion on a colossal scale. The Internet is the second major attempt to build a market-free economy, limited to information.
Today's programmers offer more valuable skills than simply being able to hack algorithms and make data structures, says Yegor Bugayenko.
Why Cryptocurrencies Use So Much Energy
The electricity consumption of mining for cryptocurrencies is becoming a real concern. Here's what to do about it.
Bringing the Internet to the (Developing) World
A growing number of low-cost (and free!) solutions aim to open the Internet to developing regions.
Blockchain Revolution Without the Blockchain?
Most of the suggested benefits of blockchain technologies do not come from elements unique to the blockchain.
"Citizen Developers" can create new applications via low-code development.
Smart Thermometers Improve Flu Forecasting
Connecting electronic thermometers to smartphones permits the capture of instant, anonymized fever readings as leading indicators of influenza outbreaks.
The world's largest navy explores the use of additive manufacturing for spare parts, with an eye toward eventually building ships that way.
Exploring Cyber Resilience for Electricity
Challenges face the use of microgrids, but they hold the potential for increased grid security.
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.
