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 challenges.
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 understand these relations and make tradeoffs in future instrument designs.
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-gravitating agglomerates scales efficiently with the number of particles as well as the number of computational resources.
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 Holdener; "Visualizing Big Data in Astronomy: The Automated Movie Production Environment Distribution and Display (AMPED) Pipeline,"...
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.
The IEEE Voting System Standards Committee is developing standards and guidelines for voting systems to create a common data format for election systems. Voting system data will be easier to export and utilize in election processes and by the general public.
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 story of bringing the Internet to Africa is one of cooperation and collaboration for the common good.

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 big data that can potentially prove useful to astronomical research.
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?
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 networking approach could replace TCP/IP, researchers setting a speed record for data transmission over copper wiring, a "digital tattoo" that unlocks...
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 and our place in it.
This installment of Computer's series highlighting the work published in IEEE Computer Society journals comes from IEEE Transactions on Mobile Computing.
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 expands on his column, speaking with Julie Hubschman about how she spent the summer with Jimmy the Robot, a walking, talking, tweeting science fiction prototype.
