Cyber Insecurity and Cyber Libertarianism

Here we are, 70 years into the computer age and after three ACM Turing Awards in the area of cryptography, and we still do not seem to know how to build secure information systems. And yet, our community marches forward with …

Can Liberty Survive the Digital Age?

Online social media have provided a megaphone for voices that might not have been heard except in limited circles. The amplifying effect, however, gives visibility to deliberate (or ignorant) misinformation, hate speech, incitement …

Ending Null Pointer Crashes

Void safety, says Bertrand Meyer, relies on type declarations and static analysis.

Combating Cancer With Data

Supercomputers will sift massive amounts of data in search of therapies that work.

Making Chips Smarter

Advances in artificial intelligence and machine learning are motivating researchers to design and build new chips to support different computing models.

Bionics in Competition

Developers of innovative assistive devices compete as a means of networking with each other.

The Internet of Things

2009 ACM Prize recipient Eric Brewer, 2004 ACM A.M. Turing Award co-recipient Vint Cerf, 2016–2017 Athena Lecturer Jennifer Rexford, ACM Grace Murray Hopper Award recipient Martin Casado, ACM Fellows Nick Feamster and Jim Kurose …

Technical Perspective: Functional Compilers

"Exploiting Vector Instructions with Generalized Stream Fusion" points out that stream fusion by itself is not well suited for generating bulk instructions such as vector or SIMD instructions.

Exploiting Vector Instructions with Generalized Stream Fusion

Programmers should not have to sacrifice code clarity or good software engineering practices to obtain performance. This work shows how to attain this goal for high-level Haskell in the domain of sequence-processing functions …

Technical Perspective: Building Knowledge Bases from Messy Data

"DeepDive: Declarative Knowledge Base Construction" is a prime example of groundbreaking work in the area of Knowledge Base Construction.

DeepDive: Declarative Knowledge Base Construction

We describe DeepDive, a system that combines database and machine learning ideas to help to develop knowledge base construction systems.
