Crowdsourced Cybersecurity: Hunting for Bugs
Companies offer big money to 'white-hat hackers' to find flaws in software products before the black hats do.
Social media "influencers" use augmented reality filtering apps to appear more beautiful, together, and cool. Results may vary.
Qubit Devices Inch Toward Reality
Key questions and challenges remain, including how to scale qubit devices while reducing noise and errors to the point where the devices become useful.
Robot Teams Win DARPA Subterranean Challenge
The teams behind the real and virtual robots named as winners shared a total of $5 million in prize money.
AI and Sustainability: Where Are We and What’s Next?
Researchers are exchanging views and proposing solutions as questions around AI's environmental impact become more urgent.
In Space, No One Can Fix Your Sign Errors
Once you've left the Earth, the simple inversion of a critical parameter can cause a mission to fail.
The Outlook for Virtual Meetups
Future online meetings could include people in disparate locations cutting a virtual birthday cake together.
Google’s AI Upscaling Technology Outperforms Previous Models
New models developed by the search giant upgrade the resolution of photos.
Interacting With Computers Through Smell
We typically interact with computers and virtual environments using vision, hearing, and touch, but there is growing interest in also incorporating smell, to replicate more closely how we interact with the real world. Odors could help people feel more present in virtual reality settings, for example, while smell could also play a role in how […]
Post-Quantum Cryptography: Protecting Today from Tomorrow
Crafting more difficult algorithms to protect secrets so they are resilient to future quantum computers is creating, in effect, post-quantum cryptography.
Algorithms can have a devastating impact on people's lives, especially if they already are struggling economically.
The introduction of the nanosheet transistor is just one step in the continuing attempt to stick to the spirit of Moore's Law.
Two-dimensional materials — graphene and its cousins — could enable better integrated circuits.
AI Calling ET: How Artificial Intelligence Supports the Search for Extraterrestrial Life
Researchers increasingly ask AI whether anybody is out there.
Dialing the Trust Level Down to Zero
With cybersecurity under increasing attacks, experts say we should move to the Zero Trust Architecture.
Floods are the most common natural disaster caused by weather, according to data from the National Severe Storms Laboratory of the U.S. National Oceanographic and Atmospheric Administration, which says floods are expected to become even more frequent, due to climate change. Often caused by extreme rainfall, floods can threaten lives and cause extensive damage to […]
GLOM: Teaching Computers to See the Way(s) We Do
Geoffrey Hinton wants to design neural networks so they have different ways of seeing the same thing.
Mining Financial Data Without Actually Seeing It Can Detect Fraud
Multiparty Computation permits computation on encrypted values.
Unmanned aerial vehicles are being used to make it rain in the desert, a first step toward controlling the weather.
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.
