Reasoning on Data Partitioning For Single-Round Multi-Join Evaluation in Massively Parallel Systems
We introduce a framework for reasoning about data partitioning to detect when we can avoid the data reshuffling step.

The Slow Evolution of CS For All, The Beauty of Programs
Mark Guzdial considers the steps needed to reach the goal of CS for All, while Robin K. Hill ponders the aesthetics of programming.
I am going way out on a limb in this column into an area where I really know very little but am completely fascinated by what I am learning. The tenuous linkage to our discipline is what I will call programmed cell self-destruction or maybe cell suicide.
Neuroscience Misses the Meaning
Examining each transistor in a microprocessor using techniques for analyzing how the human brain works did not yield anticipated understanding.
Brain scans appear to be better at discerning lies than polygraphs are.
Nae’s Newest Members Include 17 Computer Scientists
Seventeen computer scientists were among the 84 new members and 22 new foreign members recently announced by The National Academy of Engineering.
A new wave of consumer-centric connected fitness and health-related devices is changing healthcare.
It’s Not the Algorithm, It’s the Data
In risk assessment and predictive policing, biased data can yield biased results.
BBR: Congestion-Based Congestion Control
Measuring bottleneck bandwidth and round-trip propagation time.
Anyone can use a load balancer. Using it properly is much more difficult.
Computing History Beyond the U.K. and U.S.: Selected Landmarks from Continental Europe
It is past time to acknowledge 400 years of European computational innovation from non-English-speaking scientists and engineers.
Copyright Enforcement in the Digital Age: Empirical Evidence and Policy Implications
Government-sanctioned and market-based anti-piracy measures can both mitigate economic harm from piracy.
To help celebrate 50 years of the ACM Turing Award and the visionaries who have received it, ACM has launched a campaign called "Panels in Print," which takes the form of a collection of responses from Turing laureates, ACM award recipients, and other ACM experts on a given topic or trend.
Smart Machines Are Not a Threat to Humanity
Worrying about machines that are too smart distracts us from the real and present threat from machines that are too dumb.
Arguing against the arguments for the concept of the singularity.
A Messy State of the Union: Taming the Composite State Machines of TLS
We systematically test popular TLS implementations and find unexpected transitions in many of their state machines that have stayed hidden for years. We show how some of these flaws lead to critical security vulnerabilities.
Technical Perspective: Cleaning Up Flaws in TLS Implementations
One unfortunate fact about protocols is that as they get older and applied to more scenarios — and TLS is used basically everywhere — they tend to gain weight. A truism of the security community is that "complexity is the enemy of security." What is the community doing about this?
Authentication Using Pulse-Response Biometrics
We propose a new biometric based on the human body's response to an electric square pulse signal, called pulse-response.
In a series of interactive murder mysteries, I might not have done it, but, then again, maybe I did
Liberal Arts Academia Wants You!
Janet Davis makes a plea to CS practitioners to consider even a short teaching stint.
Model learning emerges as an effective method for black-box state machine models of hardware and software components.
How AI Is Changing Software Development
Artificial intelligence technologies like advanced machine learning, deep learning, and natural language processing will help build better software faster.
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.
