A Paper Trail for Voting Machines
New York Times (01/07/08) P. A25; Poundstone, William
A general mistrust of voting systems seems to be a common theme with
American voters, as a wave of electronic voting machine de-certifications
and negative reports cast doubt over new era voting machines, writes author
William Poundstone. However, paper ballots are also problematic; ballot
boxes can be lost or stuffed and it was the paper-ballot / hanging chad
fiasco in the 2000 election in Florida that led to the rapid adoption of
electronic voting machines. MIT computer scientist Ronald L. Rivest and
mathematician and voting reform advocate Warren D. Smith have proposed a
solution that combines paper ballots and a Web site to create better ballot
security than is possible with paper or e-voting alone. The concept is to
allow each voter to take home a photocopy of a randomly selected ballot
cast by someone else. Paper ballots would be tallied by optical scanners,
or even by hand, and results would be posted on a Web site. Using a serial
number assigned to each ballot, voters could check the site to make sure
that the random ballot they brought home was posted on the site and that it
was not altered or misread. Rivest and Smith believe the system creates
public accountability as any voter can check to make sure the ballots are
being counted correctly, and that only a small number of participant would
be needed to catch any fraud. The system also protects voter privacy
because the ballots distributed for authentication would be randomized and
would not contain voter information.

Demographic Crisis, Robotic Cure?
Washington Post (01/07/08) P. A12; Harden, Blaine
Japan, which has the world's largest population of residents over 65 and
the smallest proportion of children under 15, is currently on course for a
population crisis unlike any in history, and while immigration and an
increased birth rate would prevent the problem, many young women in Japan
do not want children and the country is unwilling to accept large numbers
of immigrants. The Japanese government is counting on advancements in
robotics to supplement the dwindling work force. While humanoid robots
such as Toyota's violin playing robot and Honda's ASIMO, which can dance
and serve tea, are the most popular with crowds, service robots are the
most likely to help Japan maintain its position in the global economy.
Toyota recently announced that service robots will become one of its core
businesses, and the government is heavily subsidizing the development of
service machines. One of Toyota's objectives is designing robots to help
care for the elderly. Toyota predicts that in the next 10 to 20 years the
most useful robots will be smart, highly mobile, wheelchair-like devices
that bear little resemblance to the humanoid robots from the movies.
However, many see robots as a quick fix and a politically expedient
palliative that allows politicians and corporations to avoid discussing the
difficult issues, such as Japan's strong aversion to immigration and
Japanese women's increasing rejection of motherhood. "Robots can be
useful, but they cannot come close to overcoming the problem of population
decline," says Hidenori Sakanaka, the former head of the Tokyo Immigration
Bureau and current director of the Japan Immigration Policy Institute.

Gates Hails Age of Digital Senses
BBC News (01/07/08)
Microsoft Chairman Bill Gates predicts that they way people interact with
computers will change dramatically over the next five years, with mice and
keyboards giving way to touch, vision, and speech interfaces. "This whole
idea of what I call natural user interface is really redefining the
experience," Gates says. "We're adding the ability to touch and directly
manipulate, we're adding vision so the computer can see what you're doing,
we're adding the pen, we're adding speech." As examples of the future of
user interfaces, Gates pointed to the Microsoft Surface computer, a large
table-like machine with a multi-touch interface on the surface, as well as
the iPhone and the Nintendo Wii game console. "I'll be brave, in five
years we'll have many tens of million of people sitting browsing their
photos, browsing their music, organizing their lives using this type of
touch interface," Gates says. He says that although his company has made
some mistakes over the years, he says Microsoft will surprise people with
what it plans to do in the search area. Gates also supports Vista, noting
Microsoft has sold 100 million licenses for the operating system.

Illinois Advanced Computing Institute Funds First Three
Projects
University of Illinois at Urbana-Champaign (01/03/08)
The new Institute for Advanced Computing Applications and Technologies at
the University of Illinois at Urbana-Champaign will launch three inaugural
projects this month. The first project, "Synergistic Research on Parallel
Programming for Petascale Applications," will combine potentially petascale
applications with needed computer science research, focusing on
applications that could show sustain petascale performance given the right
computer science tools. The second project, "Next-Generation Acceleration
Systems for Advanced Science and Engineering Applications," will develop
application algorithms, programming tools, and software artifacts for the
deployment of next-generation accelerators, including graphics processing
units and field-programmable gate arrays, in science and engineering
applications. The third project, "Cultural Informatics," will apply
information science and technology to the creation and understanding of the
human experience, the expression of the human condition, and the revelation
and communication of human values and meaning. This project may include
the creation of new aesthetic works, public engagement, the performing
arts, museum and other exhibition venues, and design strategies that impact
society. "These projects will bring the development and deployment
competencies of NCSA to bear on challenges in diverse disciplines and will
forge unique collaborations between Illinois faculty and NCSA staff," says
Institute and NCSA director Thom Dunning. "It's very exciting to be able
to foster such innovative work."

Pondering a Computer With a Conscience
Buffalo News (01/07/08) Continelli, Louise
Brandeis University neuroscience researcher Eliezer J. Sternberg's new
book, "Are You a Machine? The Brain, The Mind And What It Means to Be
Human," explores the possibility that computers could attain consciousness
and meld with humans. Sternberg says some experts believe that we are
close to designing super-intelligent machines capable of thinking millions
of times faster than we do, and that by the middle of the century $1,000
will buy a computer with processing power equal to the brain power of the
entire human population. Computers will also be able to create virtual
worlds that allow us to alter and escape the real world. "Instead of
calling a friend on the phone, you will be able to meet him or her at a
virtual Parisian cafe or at the top of a virtual mountain with a scenic
view," Sternberg says. "This virtual life will be as detailed as real life
in every way." In his book, Sternberg note that inventor and computer
expert Ray Kurzweil and MIT scientist Marvin Minsky believe that evolution
will ultimately combine man and machine, leading to a world where the line
between man and machine is so vague that people will not make any
distinction.

EU Project MERSA: New Processors to Make Cars More
Economical and Planes Safer
Innovations Report (01/04/08)
The European Union's "Multi-Core Execution of Hard Real-Time Applications
Supporting Analysability" (MERASA) project is working toward making cars
and planes more energy efficient, economical, and safe. Possible
improvements include ABS systems with a better performing electronic
control unit and control units that allow for optimized fuel consumption,
but such improvements require the execution of tasks within a very short
interval of time, which is known as "hard real-time constraints."
Currently, very few processors exist that can guarantee the necessary
execution deadlines. The processors used in high-performing PCs are too
expensive and are not suitable for applications in embedded systems such as
ABS or engine regulation, and processors currently used in embedded systems
have limited performance capabilities and are not able to meet the higher
standards of safety and cost-effectiveness that the future will bring. The
MERASA project is working to develop embedded processors that use
multi-core technology to satisfy hard real-time constraints. "To this end,
we at the University of Augsburg will develop new real-time-capable
processor structures in collaboration with our colleagues at the Barcelona
Supercomputing Center," says University of Augsburg computer scientist Theo
Ungerer. "We will implement them prototypically, and at the same time
design the corresponding real-time-capable operating system software here
in Augsburg." Researchers at Paul Sabatier University and at Rapita
Systems in the U.K. will deliver software tools that can calculate the
worst-case execution time required to guarantee real-time capability.

NSF Launches Mentoring Program for Minority
Students
HPC Wire (12/31/07)
The "Empowering Leadership: Computing Scholars of Tomorrow" Alliance (EL
Alliance) is targeting underrepresented minority computing students with an
Internet-based mentorship program. The new initiative will give
participants, who are often one of few minority students in their classes,
an opportunity to find needed role models in the computing fields.
Minority students often lack the support networks that are critical for
entrance into the computing industry, advancement in their field, and
overall career success. EL Alliance will find mentors based on the
preferences of students, in addition to the experience and qualities of
computing professionals. The national network is encouraging minority
students and national leaders in the computing industry to sign up for the
online mentoring program at
www.empoweringleadership.org. Rice University leads the EL Alliance,
which has ties to dozens of universities, professional societies,
laboratories, research centers, and corporations. The National Science
Foundation also supports the EL Alliance.

Fuzzy Logic Tech Project to Help the Elderly
silicon.com (01/03/08) Ferguson, Tim
Researchers in the United Kingdom and the United States are developing
prototype systems that incorporate fuzzy logic techniques into sensor
technology for monitoring the movements, capturing the sleep patterns, or
measuring the pulse and respiration of seniors. Fuzzy logic would enable
such systems to reach better conclusions about the vague information that
is picked up by sensors. For example, the system would be capable of
determining that a sound is actually a door slamming and not someone
falling, as a result of the computational mathematics of fuzzy logic, and
would ultimately generate fewer false alarms. The project begins in
January, and Dr. Simon Coupland, research fellow at the De Montfort
University Center for Computational Intelligence in Leicester, will spend
the next four months working in the United States with Jim Keller, a fuzzy
logic expert at the University of Missouri's Center for Eldercare and
Rehabilitation Technology. Such a system could still be five years away,
due to the extensive trials it must undergo and the approval that will be
needed.

The Long Nose of Innovation
Business Week (01/02/08) Buxton, Bill
Microsoft principal scientist and author Bill Buxton offers his "Long Nose
of Innovation" theory that most innovation underlying the latest "wow"
moment is low-amplitude and proceeds over a long interval, long before the
"new" idea has become general knowledge. "The low-frequency component of
the Long Nose may well outweigh the later high-frequency and (more likely)
high-visibility section in terms of dollars, time, energy, and
imagination," he writes. Buxton cites the 30-year-long gestation period of
the computer mouse, from first demonstration to mainstream penetration, as
a typical example of his theory's validity. He points to a 2003 study
presented to the National Research Council's Computer Science and
Telecommunications Board by Microsoft's Butler Lampson focusing on the
progress of key IT and telecom technologies. The report concluded that the
average gestation period was two decades, and three decades was not out of
the ordinary, leading to Buxton's contention that any technology that will
have substantial impact over the next decade has already been in existence
for at least 10 years. The author maintains that the refinement of
existing ideas is the core of the innovation process, and argues that "our
collective glorification of and fascination with so-called
invention--coupled with a lack of focus on the processes of prospecting,
mining, refining, and adding value to ideas--says to me that the message is
simply not having an effect on how we approach things in our academies,
governments, or businesses." Buxton believes innovation might take a more
balanced strategy where the amount of investment and prestige awarded to
those who refine and augment innovations is at least equal to that awarded
to the initial inventors.

Google Tool Could Search Out Hospital Superbugs
New Scientist (01/04/08) Simonite, Tom
Researchers at Bradford University, studying the prevention and control of
hospital-acquired infections, believe that the method Google uses to rank
search results could be used to help hospitals reduce the number of
"superbug" infections. Processing data from hospitals using Google's
PageRank algorithm could help focus preventative efforts more accurately by
identifying key routes of infection and transmission. "The question is,
how do bugs get from A to B?," says Clive Beggs, head of the research
group. "We don't really know that much about the epidemiology of these
infections." Beggs' colleague, mathematician Simon Shepherd, believes the
PageRank algorithm can rank routes of infection in the same way it is used
to rank search results. "Our new model is based very much on the way
Google has achieved number one status among search engines," Shepherd says.
Shepherd plans on building a similar matrix that describes all
interactions between people and objects in a hospital, based on observing
normal activity. "Obviously nurses move among patients and that can spread
infection, but they also touch light switches and lots of other surfaces
too," Shepherd says. "If you observe a network of all those interactions
you can build a matrix of with nodes in the network are in contact with
which other nodes." He says the goal is to create software that enables
hospital managers to analyze patterns and disrupt the spread of infection
by themselves.

GM Envisions Driverless Cars on Horizon
Associated Press (01/07/08) Krisher, Tom; Thomas, Ken
General Motors predicts that consumers will be able to buy vehicles that
drive and park themselves within a decade. The necessary technology, such
as radar-based cruise control, motion sensors, lane-change warning devices,
electronic stability control, and satellite-based digital mapping already
exists. Stanford University computer science professor Sebastian Thrun
agrees that the driverless car is a technically attainable goal, but he is
unsure if the automaker will have any vehicles in its showrooms in a
decade. "There's some very fundamental, basic regulations in the way of
that vision in many countries," Thrun says. He notes that the technology
has a long way to go, considering one vehicle in the recent Defense
Advanced Research Projects Agency's Urban Challenge nearly charged a
building and another pulled into a house carport and parked itself. The
contest initially drew 35 teams, but only six completed the 60-mile course,
and Thrun's team took second place.

Virtual Factory on the Tabletop
Fraunhofer-Gesellschaft (12/07)
Researchers at the Fraunhofer Institute for Computer Graphics Research IGD
in Darmstadt have teamed up with colleagues at the Steinbeis Institute
Design and Systems to develop a tabletop touchscreen that enables users to
see the hidden sequences of industrial processes. The Multi-Touch Table is
an intuitive tool that users can control with their fingers and swiping
movements. For example, the large, industrial-scale display table would
illuminate on its surface the image of a journey through pipes and machines
in a factory. Users can touch with a finger the image of individual
components, and swipe a finger over the objects to rotate, observe, and
watch the process in slow motion. And by drawing apart their two index
fingers, users can zoom in on details or enlarge the image. The Coperion
Group of companies is already using the technology. "It allows customers
to observe the entire process chain of plastics manufacturing and
processing," says IGD project manager Michael Zollner. "They can watch in
real time as the granulate flows through the pipes and regulate the speed
by swiping a finger over the image."

Coding (and Consulting) Kid-Style With Scratch
T.H.E. Journal (12/07) Schaffhauser, Dian
MIT Media Lab's Lifelong Kindergarten research group has developed
Scratch, a programming language designed to help kids learn mathematical
and computational concepts along with the process of design. A paper about
Scratch explains that the language can nurture skills in the areas of
information and communication, thinking and problem-solving, and
interpersonal and self-direction. The Scratch Web site freely offers the
program for download, examples, tutorials, and discussion forums, and
approximately 45,000 people have registered on the site thus far.
Programming via Scratch allows kids to blend together sounds, music,
graphics, and photos by dragging and dropping graphical command blocks onto
a Scripts work area. The program begins with a "sprite" character that
users can manipulate with command blocks, and starting and stopping scripts
involves the user clicking a green flag and a red stop sign button,
respectively. Students in Expo Elementary School teacher Karen Randall's
elective program classes have used Scratch to deliver consulting and
programming services for students at another school. Randall says the
language helped her team experience the process of design in a deeper and
more meaningful way. "They made products that are real pieces of software,
adapted to the needs of real clients," she says.

Software's 'Go-To Guy'
Software Development Times (12/01/07)No. 187, P. 27; Koch, Geoff
Specialist software developers are less in demand than versatile
generalists as applications become more sophisticated and complex. "In the
old days, applications were often standalone," notes Corticon Technology
executive David Straus. "Today we are trying to develop applications into
component services which are orchestrated by some [software] layer. We
want these components to be reusable and well orchestrated." Trends are
unfolding in the three biggest integrated development
environments--NetBeans, Eclipse, and Visual Studio--that are easing the
accommodation of different data types, the establishment of connections
with an assortment of SQL databases, and the masking of the complexity of
esoteric SQL syntax so that working visually with tables and rows, or even
with higher-level entities, is possible. "While broader database and
middle-tier skills are a big plus for a developer, in addition to expertise
in the presentation layer, the [database administrator] as a specialty is
still a necessary ingredient for architecturally complex projects," says
RTTS division manager Jeff Bocarsly. "It might be good to have players who
can cover either shortstop or left field on the team, but your closer is
still going to be your closer."

Conquering Complexity
Computer (12/07) Vol. 40, No. 12, P. 111; Holzmann, Gerard J.
Minor software bugs can conspire to facilitate major system failures when
combined, writes Gerard J. Holzmann of the NASA/JPL Laboratory for Reliable
Software. "The probability of any one specific combination of failures
will be extremely low, but as experience shows, this is precisely what
leads to major accidents," he notes. Holzmann points out that the addition
of fault protection and redundancy, while reducing the severity of
failures, also makes a system bigger and more complex, which can
unintentionally broaden failure modes by introducing unplanned linkages
between otherwise separate system elements. Reduction of minor software
defects can be achieved in a number of ways, including adherence to
stricter coding standards, such as the required usage of strong static
source code analyzers on every software build. Another strategy is to
boost the amount of decoupling between software components, thus separating
independent system functionality to the maximum degree possible. Executing
independent functions on physically distinct processors supplying only
restricted interfaces between them is one of the most powerful decoupling
tactics. Holzmann also suggests that defects can be contained through the
use of memory protection to ensure that multiple threads of execution in a
computer cannot corrupt each other's address space, while supplying more
margin than is required for system operation is still another approach to
defect containment. Redundancy in safety-critical code can be delivered
through the use of multiple functionality layers, while the most commonly
utilized strategy is defect detection that commences at the very beginning
of the software development process.

Can We Stop the Internet Destroying Our Planet?
New Scientist (01/03/07)No. 2637, P. 20; Mckenna, Phil
Since the February 2007 report by Berkeley National Laboratory staff
scientist Jonathan Koomey, which showed that worldwide power consumption by
servers had doubled between 2000 and 2005, numerous studies have
highlighted the increasing energy demand created by computers. A week
after Koomey's report, Microsoft, IBM, Intel, Dell, and Sun Microsystems
forged the Green Grid, a coalition dedicated to solving hardware and
software inefficiencies and reducing power consumption. Some data centers,
including Google's, use renewable energy, and there is talk of systems that
convert alternating current into direct current only once in a data center,
instead of multiple times at different servers, but such efforts are
unlikely to be enough. Every single electronic transaction, every credit
card purchase, email, download, and record retrieval, goes through a data
center, and the power cost is enormous. "Three years ago, YouTube didn't
exist," says Green Grid director Lawrence Lamers, of software company
Vmware. "Now there are hundreds of millions of videos being downloaded by
millions of users." Other efforts to improve energy conservation include
virtualizations software, which now can run on servers due to their
increased processing power. The improved power of modern servers means
that a server running only one program is generally using less than 15
percent of its capacity. Improving the efficiency of software is also
helping save power. Google, for example, uses Linux on their data centers,
which can be checked and adjusted to prevent the system from running small,
meaningless tasks. Eventually, computers will be able to adjust their
energy consumption in proportion to their workload.
