Network Applications Are Interactive
The network era requires new models, with interactions instead of algorithms.
Abstracting the Geniuses Away from Failure Testing
Ordinary users need tools that automate the selection of custom-tailored faults to inject.
Decentralized Blockchain-Based Electronic Marketplaces
In a decentralized marketplace, buyers and sellers transact directly, without manipulation by intermediary platforms.
Popularity Spikes Hurt Future Chances For Viral Propagation of Protomemes
Once a meme gets popular, it will have to evolve to keep being popular.
Information Hiding: Challenges For Forensic Experts
The practice of hiding ill-gotten data in digital objects is rising among cyber thieves. New initiatives serve to educate, train, and thwart these activities.
Consider a configuration of six dancers on a grid, where three wear blue leotards and three wear red leotards.
A technology that could supplant standard silicon transistors as Moore's Law approaches its physical limits is based on devices that work by manipulating the spin of electrons.
Evolutionary Programming Converts Darwinism Into Algorithms
Evolutionary computation strategies include a multitude of biologically inspired algorithms for optimizing problems, often those with too many variables to compare all possible scenarios.
AI Tutoring: Genius on My Shoulder
Students are being given access to an incredibly smart digital friend with unlimited patience, programmed to sense the best way to impart knowledge.
Higher Education Not Neutral on Net Neutrality
The nature of today's Internet may mean trouble for the very community that birthed it, if network neutrality rules change.
In Pursuit of an Artificial Brain
Researchers are creating artificial life to take thinking beyond the human realm; the approach could redefine artificial intelligence.
The Quantum Threat to Cryptocurrencies
Quantum computing could fundamentally break cryptocurrencies like Bitcoin and throw markets into turmoil.
Computing Is the Secret Ingredient (well, Not So Secret)
Computer science is both a powerful enabler of rapid advances in all intellectual fields and a disruptor driving furious revolutions in commerce and society worldwide.
Cybersecurity, Nuclear Security, Alan Turing, and Illogical Logic
Cyber deterrence, like nuclear deterrence, depends on our adversaries being rational enough to be deterred by our threats but us not by theirs.
Technology-Driven Changes in Work and Employment
Even when surrounded by ubiquitous computing, humans should be encouraged to do what they do better than machines.
Energy Efficiency: A New Concern For Application Software Developers
Development of energy-efficient software is hindered by a lack of knowledge and a lack of tools.
A Theory Of Pricing Private Data
We describe the foundations of a market in which those seeking access to data must pay for it and individuals are compensated for the loss of privacy they may suffer.
Automatically Accelerating Non-Numerical Programs By Architecture-Compiler Co-Design
HELIX-RC is a compiler/microprocessor co-design that opens loops to parallelization by decoupling communication from thread execution in conventional multicore architectures.
Technical Perspective: A Simple, Elegant Approach to Non-Numeric Parallelization
"Automatically Accelerating Non-Numerical Programs by Architecture-Compiler Co-Design," by Simone Campanoni, et al., proposes a modest hardware extension to support a new parallel execution model for small, non-numeric loops.
Technical Perspective: Pricing Information (and Its Implications)
"A Theory of Pricing Private Data," by Chao Li, et al., introduces a fascinating and complicated issue that arises on the buy-side of the market when buyers are interested in multiple linear functions of the same dataset.
Parallel Computational Thinking
Applications must be programmed to process instructions in parallel to take full advantage of the new multicore processors.
Perovskites Boost Solar-Cell Potential
New materials could allow cheaper, more efficient solar cells for both traditional and novel applications.
The concept of cryptocurrencies is built from forgotten ideas in research literature.
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.
