XRDS: Crossroads, The ACM Magazine for Students

The XRDS blog highlights a range of topics from conference overviews to privacy and security, from HCI to cryptography. Selected blog posts, edited for print, will be featured in every issue. Please visit xrds.acm.org/blog to read each post in its ...

Climate modeling has come a long way since von Neumann declared it a problem too hard for pencil and paper, but tailor-made for the new digital computers. As the models and computers both evolve toward ever-greater complexity, they are changing our ...

A survey of radiation modeling and circuit simulation approaches that are essential for stockpile stewardship.

On the computational resources and techniques required for imaging the Earth's crust.

Interesting problems in computational chemistry from a computer science perspective.

Scientific computing for social and modern information networks.

Analyzing massive streaming graphs efficiently requires new algorithms, data structures, and computing platforms.

Recent advances in natural language processing bring together rich representations and scalable machine learning algorithms.

Do we need to design algorithms differently if our goal is to save energy, rather than time or space? This article presents a simple and speculative thought experiment that suggests when and why the answer could be "yes."

Infrastructure clouds offer tremendous potential for scientific users, however, they face numerous challenges that must be addressed before they are widely adopted by scientific communities.

A new system allows researchers to discover, reuse, cite, and experiment upon any computational result that is published with a Verifiable Result Identifier.
