Purdue University's Science of Information Center seeks new principles to answer the question 'What is information?'
Computer science has lost not only a great scientist, but an important link to the electronic computing revolution that took place in the 1940s.
Crowdsourcing is based on a simple but powerful concept: Virtually anyone has the potential to plug in valuable information.
More than 50 years of computing literature is augmented, streamlined, and joined to powerful new tools for retrieval and analysis.
Forty-one men and women are inducted as 2010 ACM Fellows.

A new organization is being proposed that is solely intended to promote and recognize the ethical and moral behavior in graduates of computing-related degree programs as they transition to careers of service to society.
Ideally, all software should be easy to use and accessible for a wide range of people. However, software often falls short of these basic goals. We therefore need ways to help us discover usability and accessibility problems …

The history of probabilistic sequence models dates back to Markov at the turn of the last century. Though informed by decades of research, current practices are still something …
The sequence memoizer is a new hierarchical Bayesian model for discrete sequence data that captures long range dependencies and power-law characteristics, while remaining computationally attractive.
In order to advance the field, knowledge of the types of memory errors at the system level, their frequencies, and conditions that exacerbate or are unrelated to higher error rates are of critical importance.
While a large body of work exists on DRAM in lab conditions, little has been reported on real DRAM failures in large production clusters. In this paper, we analyze measurements of memory errors in a large fleet of commodity servers …
