Algebraic Fingerprints For Faster Algorithms
Algorithmic solutions to tough computational problems are making an impressive comeback.
Bare-Metal Performance For Virtual Machines with Exitless Interrupts
We present ExitLess Interrupts (ELI), a software-only approach for handling interrupts within guest virtual machines directly and securely.
Technical Perspective: Enlisting the Power of the Crowd
An important contribution of "Answering Enumeration Queries with the Crowd" is the observation that by using the crowd for the collection of new data, we are departing from the classical closed word assumption, which underlies traditional database systems.
Technical Perspective: High-Performance Virtualization: Are We Done?
"Bare-Metal Performance for Virtual Machines with Exitless Interrupts" shows how to enable a virtual machine to attain "bare metal" performance from high-speed network interface cards.
Answering Enumeration Queries with the Crowd
Hybrid human/computer database systems promise to greatly expand the usefulness of query processing by incorporating the crowd. Such systems raise many implementation questions. To address the issues, we develop statistical tools that enable users and systems developers to reason about query completeness.
Technical Perspective: In-Situ Database Management
"NoDB: Efficient Query Execution on Raw Data Files" investigates extending a DBMS so it can use the file data in situ, without having to load it first.
NoDB: Efficient Query Execution on Raw Data Files
We here present the design and roadmap of a new paradigm in database systems, called NoDB, which do not require data loading while still maintaining the whole feature set of a modern database system.
Technical Perspective: Paris Beyond Frommer’s
Can a computer automatically discover and tell us what makes Paris look so much like Paris? "What Makes Paris Look Like Paris?" offers a creative, inspiring new approach to discovering the visual style of a city like Paris.
What Makes Paris Look Like Paris?
Given a large repository of geo-tagged imagery, we seek to automatically find visual elements, for example windows, balconies, and street signs, that are most distinctive for a certain geo-spatial area, for example the city of Paris.
Digital maps can be engineered to adapt to a person's unique interests and experience in geographic space.
Connecting mathematical logic and computation, it ensures that some aspects of programming are absolute.
Smart Data Pricing: Using Economics to Manage Network Congestion
Economic incentives that alleviate congestion for Internet customers can also improve business performance for network operators.
Internet Use and Psychological Well-Being: Effects of Activity and Audience
The connection between online communication and psychological well-being depends on whom you are communicating with.

Why People Post Benevolent and Malicious Comments Online
Explaining motivations for online comments, this study looks to help establish a positive, nonthreatening online comment culture.
Hidden In-Game Intelligence in NBA Players’ Tweets
Sentiment analysis helps detect NBA players' pre-game moods from their tweets and predict their on-court performance.
Inductive Programming Meets the Real World
Inductive programming can liberate users from performing tedious and repetitive tasks.
Technical Perspective: Treating Networks Like Programs
"Software Dataplane Verification" takes existing static checking of networks to a new level by checking the real code in the forwarding path of a Click router using classical software verification tools, and not just a model of router software as in previous work.
Technical Perspective: The Path to Light Transport
"Geometric Tools for Exploring Manifolds of Light Transport Paths" presents a technique to address the challenging problems of light transport.
Software Dataplane Verification
We present the result of working iteratively on two tasks: designing a domain-specific verification tool for packet-processing software, while trying to identify a minimal set of restrictions that packet-processing software must satisfy in order to be verification-friendly.
Geometric Tools For Exploring Manifolds of Light Transport Paths
We provide a geometric solution to the longstanding problem of light simulations by representing light paths as points in an abstract high-dimensional configuration space that is defined by a system of constraint equations.
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.
