Blog: Microsoft to developers - Here's how touch is supposed to work

By Adrian Kingsley-Hughes | February 23, 2012, 12:34am PST
Summary: Good news for users … unless they’re a south paw.
Microsoft has released a document that tells developers how touch should work for Metro UI apps on Windows 8 systems.
While a lot of what’s in the four-page PDF document is common sense, there’s also some interesting research contained in the document. For example, the document highlights the best areas on a tablet screen for interaction and reading:

Blog: IBM Says Future Computers Will Be Constant Learners

IBM Says Future Computers Will Be Constant Learners
IDG News Service (02/17/12) Joab Jackson

Tomorrow's computers will constantly improve their understanding of the data they work with, which will help them provide users with more appropriate information, predicts IBM fellow David Ferrucci, who led the development of IBM's Watson artificial intelligence technology. Computers in the future "will not necessarily require us to sit down and explicitly program them, but through continuous interaction with humans they will start to understand the kind of data and the kind of computation we need," according to Ferrucci. He says the key to the Watson technology is that it queries both itself and its users for feedback on its answers. "As you use the system, it will follow up with you and ask you questions that will help improve its confidence of its answer," Ferrucci notes. IBM is now working with Columbia University researchers to adapt Watson so it can offer medical diagnosis and treatment. Watson could serve as a diagnostic assistant and offer treatment plans, says Columbia professor Herbert Chase. Watson also could find clinical trials for the patient to participate in. "Watson has bridged the information gap, and its potential for improving health care and reducing costs is immense," Chase says.

Blog: Weave Open Source Data Visualization Offers Power, Flexibility

Weave Open Source Data Visualization Offers Power, Flexibility
Computerworld (02/08/12) Sharon Machlis

The open source Weave project is a platform designed to make it easier for government agencies, nonprofits, and corporate users to offer the public a way to analyze data. The platform enables users to simultaneously highlight items on multiple visualizations, including map, map legend, bar chart, and scatter plot. The benefits of Weave's interactivity go beyond the visual appeal of selecting an area on a chart and seeing matches highlighted on a map, notes Connecticut Data Collaborative project coordinator James Farnam. Weave aims to help organizations democratize data visualization tools, creating a way for anyone interested in a topic to explore and analyze information about it, instead of leaving the task solely to computer and data specialists, says Georges G. Grinstein, director of the University of Massachusetts at Lowell's Institute for Visualization and Perception Research, which created Weave. "Now [you're] engaging the public in a dialog with the data," Grinstein says. "That's why Weave is open source and free." Weave is so powerful that one of the challenges of implementing it is how to narrow down its offerings so that end users would not be overwhelmed with too many options, says the Metropolitan Area Planning Council's Holly St. Clair.

Blog: New Center Developing Computational Bioresearch Tool

New Center Developing Computational Bioresearch Tool
University of Chicago (01/27/12) Steve Koppes

University of Chicago researchers led by professor Gregory Voth are developing a technique that might lead to a new and simpler way to predict molecular motion inside a cell. The research is backed by a $1.5 million grant from the U.S. National Science Foundation (NSF), which is being used to launch the Center for Multiscale Theory and Simulation. "What's impressive about Greg's team is the variety of theoretical and computational tools that it brings to bear," says NSF's Katharine Covert. The tools include a theoretical and computer simulation capability for describing biological systems at interconnected multiple scales. "This is what we call the multi-scale problem, and probably nowhere in the natural world does the multi-scale problem manifest as dramatically as in the biology regime," Voth says. The center will use an extensive new cyberinfrastructure network, which will provide a wide range of computational equipment, software, and techniques to support its work. One of the center’s most important computational tools is a technique called coarse-graining, which is a way of simplifying a complex problem in a mathematically precise way, with real-world physics built in.

Blog: The Mathematics of Taste

The Mathematics of Taste
MIT News (01/24/12) Larry Hardesty

Massachusetts Institute of Technology (MIT) researchers used genetic programming, in which mathematical models compete with each other to fit the available data and then cross-pollinate to produce more accurate models, to analyze taste-test data. Swiss flavor company Givaudan asked researchers at MIT's Computer Science and Artificial Intelligence Laboratory (CSAIL) to help interpret the results of taste tests in which 69 subjects assessed 36 different combinations of seven basic flavors. For each subject, the researchers randomly generated a mathematical function that predicted scores according to the concentrations of different flavors. After all of the functions were assessed, the best ones were recombined to produce a new generation of functions, and the whole process was repeated about 30 times. To establish the model's accuracy, the CSAIL researchers developed another model to validate their approach. Taste preference "is a pretty brilliant area in which to apply the evolutionary methods--and it looks as though they're working, also, so that's exciting," says Hampshire College professor Lee Spector.

Blog: Twitter Bots Create Surprising New Social Connections

Twitter Bots Create Surprising New Social Connections
Technology Review (01/23/12) Mike Orcutt

A group of freelance Web researchers have created a Twitter bot, called a socialbot, that can fool users into thinking the bots are real people and serve as virtual social connector, accelerating the natural rate of human-to-human communication. The system grew out of the Web Ecology Project, an independent research group focused on studying the structure of social media phenomena. Some of the Web Ecology Project researchers, led by Tim Hwang, created their own organization, called the Pacific Social Architecting Corp., to continue the development of socialbots. In further experiments, the group tracked 2,700 Twitter users, divided into randomly assigned target groups of 300, over 54 days. The first 33 days served as a control period, during which no socialbots were deployed. Then, during the 21-day experimental period, nine bots were activated, one for each target group. On average, each bot gained 62 new followers and received 33 incoming tweets. The researchers also found that there was a 43 percent increase in human-to-human follows, after the socialbots were introduced, compared to the control period.

Blog: Five Open Source Technologies for 2012

Five Open Source Technologies for 2012
IDG News Service (12/28/11) Joab Jackson

Five open source projects could become the basis for new businesses and industries in 2012. Nginx, a Web server program, could become popular due to its ability to easily handle high-volume traffic. Nginx already is used on highly trafficked Web sites, and the next release, due in 2012, will be more pliable for shared hosting environments. The OpenStack cloud computing platform has gained support from several technology firms due to its scalability. "We're not talking about [using OpenStack to run a] cloud of 100 servers or even 1,000 servers, but tens of thousands of servers," says OpenStack Project Policy Board's Jonathan Bryce. Stig was designed for the unique workloads of social networking sites, according to its developers. The data store's architecture allows for inferential searching, enabling users and applications to look for connections between disparate pieces of information. Linux Mint was designed specifically for users who want a desktop operating system and do not want to learn more about how Linux works. The Linux Mint project is now the fourth most popular desktop operating system in the world. GlusterFS is one of the fastest growing storage software systems on the market, as downloads have increased by 300 percent in the last year.
