Improving Social Alignment During Digital Transformation
Exploring what leaders can do to improve and sustain social alignment over time.
Keeping CALM: When Distributed Consistency Is Easy
In distributed systems theory, CALM presents a result that delineates the frontier of the possible.
Computing Value of Spatiotemporal Information
We investigate the intrinsic value of location data in the context of strong privacy, where location information is only available from end users via purchase.
Technical Perspective: Progress in Spatial Computing for Flood Prediction
There are few algorithms for multi-flow graphs beyond flow accumulation. The authors of "Flood-Risk Analysis on Terrains" take a big step to fill this knowledge gap.
Flood-Risk Analysis on Terrains
In this paper, we study a number of flood-risk related problems, give an overview of efficient algorithms for them, as well as explore the efficacy and efficiency of these algorithms on real terrains.
Technical Perspective: Computing the Value of Location Data
"Computing Value of Spatiotemporal Information," by Heba Aly et al., describes a technique for computing the monetary value of a person's location data for a potential geo-marketplace.
Digital Creativity Support for Original Journalism
A tool that helps journalists discover new story angles by offering insight not search results.
Examining Undergraduate Computer Science Participation in North Carolina
Data on CS graduation rates among six academic institutions in NC traces the demographics of those participating (or not) in the discipline.
Why Computing Belongs Within the Social Sciences
Fully appreciating the overarching scope of CS requires weaving more than ethics into the reigning curricula.
Threats of a Replication Crisis in Empirical Computer Science
Research replication only works if there is confidence built into the results.
Technical Perspective: Entity Matching with Magellan
Magellan's key insight is that a successful entity matching system must offer a versatile system building paradigm for entity matching that can be easily adapted for different application needs.
Technical Perspective: Supporting Linear Algebra Operations in SQL
Do we need a completely new database system to support machine learning?
Scalable Linear Algebra on a Relational Database System
We show that by making just a few changes to a parallel/distributed relational database system, such a system can become a competitive platform for scalable linear algebra.
Magellan: Toward Building Ecosystems of Entity Matching Solutions
Entity matching can be viewed as a special class of data science problems and thus can benefit from system building ideas in data science.
Spectre Attacks: Exploiting Speculative Execution
This paper describes practical attacks that combine methodology from side-channel attacks, fault attacks, and return-oriented programming that can read arbitrary memory from the victim's process.
Technical Perspective: Why ‘Correct’ Computers Can Leak Your Information
"Spectre Attacks: Exploiting Speculative Execution," by Paul Kocher, et al., reviews how speculative execution and caches can be exploited, presents specific exploits using speculative branches that are direct and indirect, and discusses software and hardware options for mitigating Spectre.
Technical Perspective: ASIC Clouds: Specializing the Datacenter
Can we build purpose-built, warehouse-scale datacenters customized for large-scale arrays of ASIC accelerators or, to use a term coined in the paper by Michael Bedford Taylor, et al., ASIC clouds?
The Data Science Life Cycle: A Disciplined Approach to Advancing Data Science as a Science
A cycle that traces ways to define the landscape of data science.
Domain-Specific Hardware Accelerators
DSAs gain efficiency from specialization and performance from parallelism.
A Domain-Specific Supercomputer for Training Deep Neural Networks
Google's TPU supercomputers train deep neural networks 50x faster than general-purpose supercomputers running a high-performance computing benchmark.
Some Simple Economics of the Blockchain
Blockchain technology can shape innovation and competition in digital platforms, but under what conditions?
ASIC Clouds: Specializing the Datacenter for Planet-Scale Applications
This paper distills lessons from Bitcoin ASIC Clouds and applies them to other large scale workloads, showing superior TCO (total cost of ownership) versus CPU and GPU.
The ‘Invisible’ Materiality of Information Technology
It's difficult to see the ecological impact of IT when its benefits are so blindingly bright.
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.
