The Push for Stricter Rules for Internet Platforms
Considering the origins, interpretations, and possible changes to Communications Decency Act §230 amid an evolving online environment.
Out-of-This-World Additive Manufacturing
From thingamabobs to rockets, 3D printing takes many forms.
The Decline of Computers as a General Purpose Technology
Technological and economic forces are now pushing computing away from being general purpose and toward specialization.
The first programmable electronic general-purpose digital computer was introduced to the world on Valentine’s Day in 1946.
Driving the Cloud to True Zero Carbon
Climate change has come to the fore as a business concern, and this compels the business leaders of computing technology companies to be on the side of progress toward true zero carbon.
Technical Perspective: Solving the Signal Reconstruction Problem at Scale
"Scalable Signal Reconstruction for a Broad Range of Applications," by Abolfazl Asudeh, et al. shows that algorithmic insights about SRP, combined with database techniques, can be used to scalably solve the signal reconstruction problem.
The State of Virtual Reality Hardware
Advances in VR hardware could finally take the technology mainstream.
Keeping Science on Keel When Software Moves
An approach to reproducibility problems related to porting software across machines and compilers.
Scalable Signal Reconstruction for a Broad Range of Applications
Most of the common approaches for solving signal reconstruction problem do not scale to large problem sizes. We propose a novel and scalable algorithm for solving this critical problem.
Finally, Apps to Sink Your Teeth Into
Developers are beginning to incorporate teeth into new technologies.
Autonomous Shipping Charts Its Course
The maritime industry wades into digitalization; will it float?
Technical Perspective: SkyCore’s Architecture Takes It to the ‘Edge’
"SkyCore," by Mehrdad Moradi, et al., addresses an exciting use case for Unmanned Aerial Vehicles in which UAVs can act as mobile base stations for the cellular network, flying to areas in the network in order to improve wireless connectivity.
Deliberating on how to regulate—or not regulate—online speech in the era of evolving social media.
SkyCore: Moving Core to the Edge for Untethered and Reliable UAV-Based LTE Networks
We argue for and propose an alternate, radical edge evolved packet core design, called SkyCore, that pushes the EPC functionality to the extreme edge of the core network.
The field of haptics—the use of technology to simulate touch, feeling, and motion—is finally hitting its stride.
The Next Best Thing to Being There
Encouraged by the pandemic, augmented and mixed realities bring new views to end-users in medicine, industry, and the military.
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.
