Revisiting ACM Europe

ACM Europe was launched in October 2009 in Paris. Since then, the ACM Europe Council has grown to 21 members with a good mix of nationality (although mostly European, of course), gender, and research interests.

Credit Non-Anonymous Reviewers with a Name

I agree with Bertrand Meyer's blog "Fixing the Process of Computer Science Refereeing" (Nov. 2011) and "Why I Sign My Reviews" in favor of open reviewing but suggest we go further with the quality of refereeing by rewarding …

Researchers' Big Data Crisis; Understanding Design and Functionality

Michael Stonebraker issues a call to arms about research groups' data-management problems. Jason Hong discusses the nature of functionality with respect to design.

The Science of Better Science

Researchers are exploring networked computational analysis, formal classification, and topic modeling to better identify relevant scientists, ideas, and trends.

The War Against Botnets

Increasingly sophisticated botnets have emerged during the last several years. However, security researchers, businesses, and governments are attacking botnets from a number of different angles — and sometimes winning.

The Social Life of Robots

Researchers are trying to build robots capable of working together with minimal human supervision. But will they ever learn to get along?

Technical Perspective: Compiling What to How

The following paper by Viktor Kuncak et al. integrates declarative programming into a general-purpose language, allowing one to escape the host language when a subproblem can be solved declaratively.

Software Synthesis Procedures

Automated synthesis of program fragments from specifications can make programs easier to write and easier to reason about. To integrate synthesis into programming languages, software synthesis algorithms should behave in a predictable …

Technical Perspective: Modeling High-Dimensional Data

Data in high dimension is difficult to visualize and understand. This has always been the case and is even more apparent now with the availability of large high-dimensional datasets and the need to make sense of them.

Disentangling Gaussians

The Gaussian mixture model is one of the oldest and most widely used statistical models. Our work focuses on the case where the mixture consists of a small but unknown number of Gaussian "components" that may overlap

Puzzled: Where Sets Meet (Venn Diagrams)

Welcome to three new puzzles. The theme is Venn diagrams, those ubiquitous but useful pictures, usually consisting of two or three intersecting circles that illustrate how sets meet.
