The story of bringing the Internet to Africa is one of cooperation and collaboration for the common good. The first Web extra at http://youtu.be/5LXvSs_zugk is a video interview in which author Charles Severance speaks with Nii Quaynor about how the ...

A summary of articles published in Computer 32 and 16 years ago.

Letters from Computer's readers. An Erratum is included for an article in the August 2014 issue (doi: 10.1109/MC.2014.208).

Topics include Russian hackers stealing more than 1 billion usernames and passwords, researchers developing a new type of brain-inspired chip, a US judge rejecting a Silicon Valley corporate-collusion settlement, proponents saying that their new ...

Advances in computing have empowered astronomers to explore the universe in greater detail. Software-defined instruments relying on digital data capture and processing are more powerful than ever and continue to bring us new knowledge about the universe ...

Dramatic increases in the amount and complexity of stellar data must be matched by new or refined algorithms that can help scientists make sense of this data and so better understand the universe. ParaHeap-k is a parallel cluster algorithm for analyzing ...

To study the evolution of small solar system bodies like asteroids and comets, a fast method is needed to compute the self-gravity of systems composed of millions of particles. A proposed fully parallel shared-memory algorithm for dense, self-...

Pydron, a system that bridges the gap between interactive data analysis and scalable computing, enables astronomers to process large datasets with Python without the complexities of managing parallel processing code.

For next-generation radio telescopes such as the Square Kilometre Array, seemingly minor changes in scientific constraints can easily push computing requirements into the exascale domain. The authors propose a model for engineers and astronomers to ...

IceCube--a neutrino telescope that encompasses a cubic kilometer of Antarctic ice at the South Pole, collecting and processing data from 5,160 optical sensors buried a mile deep in the icecap--presents considerable challenges, from overcoming power and ...

This article includes the following "mini-articles" about applications and examples of computing in astronomy: "Visualizing the Universe: Using Modern Graphics Cards to Understand the Physical World," by F. Alexander Bogert, Nicholas Smith, and John ...

A risk-based cybersecurity framework must continuously assimilate new information and track changing stakeholder priorities and adversarial capabilities, using decision-analysis tools to link technical data with expert judgment.

After decades of a cache, DRAM, and disk data storage hierarchy, new memory technologies are promising nonvolatility, high endurance, and fine-grained data access--all of which could, with some preparation, enable a new storage paradigm in server ...

Every summer, Intel brings in droves of interns from schools and universities all over the world. This summer, Jimmy the Robot got one of his own. The Web extra at http://youtu.be/YTDVIzu4oa4 is an audio podcast in which author Brian David Johnson ...

In the near future, we might be able to use biometric analytics to help answer everyday questions such as: Is the speaker on TV being honest? How much money will I need for retirement? Will using this cosmetic really make me look younger?

After observing and developing online reference websites for 20 plus years, it's clear the biggest hurdle to reliability still hasn't been overcome.

Crowdsourced quality-of-experience (QoE) assessments are more cost-effective and flexible than traditional in-lab evaluations but require careful test design, innovative incentive mechanisms, and technical expertise to address various implementation ...

A newly developed instrument provides sophisticated content analysis to help determine the relevance for software security of the National Institute of Standards and Technology's FISMA-mandated security controls.

Will the next computing innovation arrive in spring 2017 on the tail of a recession? The Web extra at http://youtu.be/TYae_47GYIM is an audio recording in which author David Alan Grier discusses how the next computing innovation could very well arrive ...
