Senators: No Need for Paper E-Voting Trails, 'Electronic'
Ones Are OK
CNet (05/23/08) Broache, Anne
Senators Dianne Feinstein (D-Calif.) and Bob Bennett (R-Utah), who lead a
Senate committee that oversees election law, say they will introduce a bill
that requires precincts using touch-screen or direct-recording electronic
voting machines to equip them with independent paper, electronic, audio,
video, or pictorial records that would allow voters to verify their
selections. ACM advisory committee member and Princeton University
professor Edward Felten said that he could not comment on the new bill
without seeing more details first. The bill indicates that the senators at
least partially acknowledge the argument that paper trails are not the only
option for independently verifying a voter's selections and that other
innovative technologies could emerge in the future. The bill may also be
intended to appease state and local election officials who frequently
complain about the costs associated with outfitting their machines with
paper trails. In addition to a verification system, the bill would require
states to provide public audits of their election results, would establish
certain security requirements for the voting machines and their software,
and would establish a research grant program designed to encourage the
development and testing of new technologies for verifying votes. The bill
would take effect on January 1, 2012, but states could request a waver that
would extend the deadline to the beginning of 2014.

Conference Takes on Tech's Future
Mercury News (05/24/08) Ackerman, Elise
Conference participants at this year's Computers, Freedom and Privacy
conference focused on composing an open letter to the next president of the
United States, calling for more thoughtful attention to technology. "It
has been over 30 years since the advent of the Internet, yet we are still
in the early stages of the digitized and networked world," an early draft
of the letter states. Some of the core issues that continually resurfaced
at ACM's four-day conference were government data collection, network
neutrality, intellectual property, and patents. Jon Pincus, a consultant
who organized the letter-writing effort, says many people are not being
heard and they have no way to participate in the process, and that the
letter, which is being edited and adjusted as a public wiki, gives a voice
to those people. Other areas of interest at the conference included
discussions on the more than 50 new Fusion Centers the Homeland Security
Department has launched to share information such as financial, criminal,
education, and medical records, and the challenges of dealing with spyware.
Content filtering by Internet service providers also was an area of
concern. University of Colorado Law School professor Paul Ohm said that
ISPs may be violating a federal wire-tapping statute when they intercept
customers' traffic in an attempt to stop copyright violations, manage their
broadband networks, or target ads.

Yale Computer Scientists Devise a 'P4P' System for
Efficient Internet Usage
Yale University (05/27/08) Emanuel, Janet Rettig
Yale University researchers have developed a system that could make the
Internet more efficient by enabling Internet service providers (ISPs) and
peer-to-peer (P2P) software providers to work cooperatively to deliver
data. Yale professors Avi Silberschatz and Y. Richard Yang, and PhD
candidate Haiyong Xie are part of a research team proposing an architecture
called provider portal for P2P applications (P4P), which allow for explicit
and seamless communications between ISPs and P2P applications. P4P will
reduce the cost to ISPs and improve the performance of P2P applications,
according to a paper on the architecture that will be presented at ACM
SIGCOMM 2008. Silberschatz says current P2P information exchange schemes
are "network oblivious," and they use intricate protocols for tapping the
bandwidth of participating users to transmit data, which is both
inefficient and costly. The P4P architecture extends the Internet
architecture by providing each ISP with servers called iTrackers, which
provide portals to the operation of ISP networks. P4P can operate in
multiple modes. In simple mode, the ISPs will reveal their network status
so P2P applications can avoid hot spots. In another mode, P4P operates
much like a commodities exchange, allowing providers to interact freely to
create the most efficient information and cost flow, lowering the cost of
operation and making access to individual sites less likely to overload.
In a field test conducted using the P2P software, P4P was able to reduce
inter-ISP traffic by an average of 34 percent, and increased delivery
speeds to end users by up to 235 percent across U.S. networks and up to 898
percent across international networks.

The Line Between Reality and Reality Shows Blurs
Buffalo News (05/27/08) Watson, Stephen T.
University of Buffalo researchers say that people who watch a lot of
reality TV mimic the behavior they see on the shows and try to become
celebrities themselves, using outlets such as Facebook and other
social-networking sites. "Across the board, consistently, it was only
reality TV that predicted this set of behaviors online," says University of
Buffalo professor Michael Stefanone. The researchers studied college
students in Buffalo and Hawaii and found that media consumers will model
their own behavior after the behavior of celebrities they follow closely.
The study, "We're All Stars Now: Reality Television, Web 2.0 and Mediated
Identities," found that the biggest reality TV fans share the greatest
amount of personal information with the widest network of acquaintances on
social-networking sites, with some users collecting hundreds of online
"friends," many of whom they have never met in real life. Regular viewers
of reality shows tend to want to act like reality TV celebrities, and
online celebrity hopefuls also are more likely to befriend people they do
not know online, a behavior known as "promiscuous friending." Much of the
behavior on Facebook and MySpace is considered "fame-seeking" as people try
to create new identities and get attention, the researchers say. The study
will be published next month in the proceedings of the 2008 ACM Conference
on Hypertext and Hypermedia.

Mars Lander Communications Successfully Linked
NextGov.com (05/27/08) Aitoro, Jill R.
NASA's Phoenix lander includes special software that will help NASA
discover if life can exist on Mars. After landing, Phoenix started sending
back photos of the planet's northern plains, and the lander will soon scoop
soil and ice from the Mars surface as well as examine the atmosphere using
laser beams capable of measuring the height and thickness of clouds, wind
speed, and elevation temperatures. The analysis could reveal the movement
of water from air to soil, enabling scientists to use the information to
determine if the planet is habitable. NASA's ability to communicate with
Phoenix directly from Earth is key to the mission, which required Lockheed
Martin to compile more than 100,000 lines of code, with a second, identical
program providing redundancy. All data from the lander is downlinked
through the Mars Odyssey or Mars Reconnaissance orbiters, which NASA
launched in 2001 and 2005, respectively. Data is then retransmitted to one
of three ground-based antennas, known as the NASA Deep Space Network,
strategically located worldwide to guarantee that one antenna is facing
towards Mars at all times. The data is sent to ground control computers at
NASA's Jet Propulsion Laboratory and the University of Arizona.
Researchers then decide what action Phoenix should take and send commands
and sequences back to the lander through the same communications
channel.

Women Execs Fight the Silicon Ceiling
Seattle Times (05/26/08) Cassidy, Mike
The panel discussion on women in technology at the recent Red Herring
North America conference in San Jose had a small turnout that reflects the
difficult situation that women in technology face. Part of the problem is
that discussions on women in technology usually cite the same issues--lower
female enrollment in technology degree programs, few female tech CEOs, and
a male-dominated technology culture. Panelist Penny Herscher, CEO of
FirstRain, said she has been working in or running technology companies for
more than 25 years so she knows what it is like to be a woman in a man's
world. Herscher recalled a time when she and her male chief operating
officer sat down with a team of journalists. Herscher answered the first
two questions, but then a reporter stopped her and said they were only
interested in talking with the executives. Infobright CEO Miriam Tuerk
once hired a man to round out her all-female executive team because she
feared that an all-female team would never get funding. Nevertheless,
Herscher said she sees reasons for optimism and noted that the atmosphere
and attitudes in Silicon Valley are drastically different from when she
started. She said women are more readily accepted as equals, more quickly
seen as executive material, and female CEOs do not have to come from a
company's tech ranks. Herscher is on the board of the Anita Borg Institute
for Women and Technology, which encourages women to pursue technology
careers. Herscher said organizations and individuals need to reach out to
middle-school and high-school girls to fight the stereotype that math is
nerdy and boys are better suited for tech careers. "I think we change
things by getting involved," she said. "By leading by example."

MIT Researchers: Morphing Web Sites Could Bring
Riches
Network World (05/22/08) Greene, Tim
MIT researchers say that Web sites capable of customizing themselves for
each visitor so that they are more appealing, or less annoying, could
significantly boost sales. Sites capable of displaying information that is
best suited to each individual visitor and their preferred style of
absorbing information would tailor themselves based on the decisions
visitors make as they browse through pages on the site. A site might play
an audio file and present graphics to one visitor, but present that same
information as text to another depending on the user's cognitive style.
MIT's John Hauser says it takes between five to 10 clicks to get a good
idea of a user's viewing preferences, and that statistics have evolved over
the past decade that allow people to make broader conclusions from less
data. By using a sample set of users navigating a test Web site, a
business could set the baseline for how click choices determine what type
of site a user sees. As real potential customers visit a live site, the
morphing engine fine-tunes itself to create sites that fit a user's
preferences even better, increasing the likelihood of a sale. The open
source morphing engine is available on MIT's Web site. The researchers say
auto-customized sites are less intrusive than sites that visitors can
manually customize, which is a time-consuming process that many users will
not even bother with, and auto-customized sites generate more sales faster
than other sites. The researchers found that if a site had perfect
information about each person's cognitive style, it could increase sales by
21 percent, and even if the program had only partially known cognitive
styles, the site could improve sales by nearly 20 percent.

Profits for Publishers in Making Books Accessible to
All
ICT Results (05/23/08)
Facilitating on-demand accessibility to books for the visually impaired
through the adaptation of new technologies is the goal of European
researchers who have brought together the European publishing industry and
accessibility organizations to pool their knowledge and give birth to a new
type of publishing. "It's no longer a question of publishers being told
'you must give us this,' but of everybody sitting around a table and
talking about markets and how to best serve them while ensuring a profit
for the publishers," says EUAIN project coordinator David Crombie. He says
the EUAIN project is unique in that it involves permitting access to
documents in any digital format. Crombie stresses the importance of
including different sets of formatting instructions from the beginning of
the publishing process. An entirely new mainstream market could be
supported with synthesized print and audio titles, which deliver a wholly
new experience for users through the employment of a speech synthesizer on
the computer reading instructions from the electronic book file. In the
wake of the now-completed EUAIN project is a new association and spinoff
initiatives focusing on the establishment of standards and industry
guidelines and the production of training materials and courses. The EUAIN
project partners are also attempting to create a new entity that will use
the Open Document Format to make it possible for publishers to
electronically link to the system and automatically format their books for
accessibility.

Strokable Robot Rabbit Talks With Touch
New Scientist (05/22/08) Barras, Colin
Haptic Creature, a pet robot rabbit that responds to human touch, is being
used to explore how touch strengthens emotional relationships. The study
could be used to make relationships between humans and robots more
emotionally rewarding. University of British Columbia computer science PhD
candidate Steve Yohanan says robotics researchers often neglect haptics as
a form of communication, instead focusing on sounds and vision. Haptic
Creature is designed to recreate the touch-based communication many pet
owners experience to add an element of emotion to human-robot interactions.
The rabbit-looking robot is covered with fur and uses pressure sensors to
detect when it is touched or stroked. It responds with breathing
movements, inaudible purring vibrations, or by moving its ears. Yohanan
says even those simple responses can elicit a variety of human emotions.
United States Naval Academy applied mathematician Sommer Gentry says the
importance of haptic interaction on how people use technology has long been
neglected. "I am not sure whether it is the technical challenges of
human-robot haptic interaction, or under-appreciation of the potential for
these technologies that make this a relatively immature area," Gentry
says.

Designers Draft Multicore Programming Guide
EE Times (05/22/08) Merritt, Rick
A guide on how to write code for embedded multicore processors could be
available within a year. The Multicore Association has created a new
working group to define the pressing issues involving parallel computing
and to create a guide on the best programming practices. "I see this as
the 'Read Me' document for anyone doing multicore programming," says David
Stewart, co-chair of the working group. "We'll try to get a consensus from
a significant cross section of the industry on what are the top 10 or 20
issues and the best ways to handle them." An open meeting will be held at
the Design Automation Conference in Anaheim, California, on June 10 in an
effort to drawing other opinions. Issues using C and C++ will be an
initial focus of the group, but it is also expects to address code
dependencies, inter-process communications, and race conditions.

A Robotic Brain-Computer Interface
ZDNet (05/21/08) Piquepaille, Roland
California Institute of Technology engineers have developed a robotic
device that can act as a brain-computer interface. They say their device
is the first robotic approach to establishing an interface between the
brain and computers by positioning electrodes in brain tissue. The device
could enhance the performance and longevity of emerging neural prosthetics,
which allow paralyzed and disabled people to operate computers and robots
with their mind. The research, led by Michael Wolf, Joel Burdick, Jorge
Cham and Edward Branchaud, consisted of implanting a small robotic device
and the accompanying control algorithm with many individually motorized
electrodes that each autonomously locate, isolate and track a neuron for
extended periods of time. The goal is to find signals only from neurons
dedicated to a particular task, such as controlling an arm's movement. The
Caltech team made the procedure more predictable by attaching a tiny
MEMS-based motor to each electrode on a multichannel electrode array, and
by using an algorithm to direct the electrodes to individual neurons. The
algorithm makes neural connections by moving the electrode to different
positions, taking sample recordings to detect spikes of electrical activity
at the electrode tip and moving the electrode around until it finds the
best signal. The researchers say they designed their neuron-tracking
algorithm by examining software used by the U.S. military to track
planes.

Brazilian Beetles Hold Key to Faster Computers
Wired News (05/23/08) Keim, Brandon
Optical computer researchers hope to be able to use the scales of the
inch-long Brazilian beetle Lamprocyphus augustus as a semiconductor mold to
build the perfect photonic crystal. The beetle's iridescent green scales
were discovered by Brigham Young University student Lauren Richey. Richey
asked BYU doctoral chemistry student Jeremy Galusha to examine the beetle
with an electron microscope. While looking at the scales under the
microscope, they noticed that no matter what angle the scales were viewed
at they always appeared the same shade of green, an unusual trait for
iridescent surfaces. Further study showed that the trait comes from the
scales' molecular arrangement, which has the same pattern as the atoms of
carbon in a diamond. Diamonds have the perfect configuration, but are too
dense to serve as photonic crystals, and laboratory attempts at mimicking
diamonds have been largely unsuccessful. Researchers say the beetle's
scales could possibly be used as a mold for optical chips, with the scale's
chitin being replaced with a semiconductor material.

Graphene-Based Gadgets May Only Be Few Years Away
Asian News International (05/26/08)
Researchers at the University of Manchester have demonstrated the first
liquid crystal devices with graphene electrodes. Dr. Kostya Novoselov has
shown that dissolving chunks of graphite into graphene and then spraying
the suspension onto a glass surface is a cost-effective way to produce
highly transparent and very conductive ultra-thin films. "Graphene is only
one atom thick, optically transparent, chemically inert, and an excellent
conductor," Novoselov says. Gadgets such as common liquid crystal displays
for computers, TVs, and mobile phones make use of transparent conducting
films, but the underlying technology relies on thin metal-oxide films based
on indium, which is expensive and is likely to be exhausted in a decade,
says professor Andre Geim. "Scientists have an urgent task on their hands
to find new types of conductive transparent films," he says. Novoselov
believes graphene-based computers and TV displays could be mass produced in
a few years.

Are Commercial Computing Clouds Ready for High-Energy
Physics?
Symmetry Magazine (05/23/08) Chui, Glennda
Amazon's Simple Storage Service (S3) and Elastic Compute Cloud (EC2) are
not yet ready to handle the weighty computation requirements of high-energy
physics research, according to a new study from the University of South
Florida's Mayur Palankar and Adriana Iamnitchi, the University of British
Columbia's Matei Ripeanu, and Harvard University's Simson Garfinkel.
High-energy physics experiments generate an incredible volume of data that
is rapidly swelling, and Fermilab's Gabriele Garzoglio says that a
business-provided external system capable of accommodating so much data has
yet to be seen. Iamnitchi notes that the S3 system's advertised
reliability appears to hold true, but she says the Amazon services would
carry a significantly higher cost than the system currently in place for
the DZero experiment at Fermilab's Tevatron accelerator. Handling the
volume of data produced by DZero through Amazon would cost $691,000
annually for storage and $335,000 for transfer, amounting to approximately
$1 million per year at U.S. rates. Strategies for lowering this cost
outlined by the study include archiving infrequently accessed data files in
some cheaper form of storage, or the separation of Amazon's three offered
performance traits so that users are only charged for the ones they want.
Although the S3 service agreement promises to remunerate users for system
failures, Iamnitchi points out that "there is no way you can prove to a
court, for example, that they lost your data." Also problematic is the
absence of any way for Amazon users to search across all their data
buckets.

Computers With Attitude
Cairns Post (05/22/08)
A group of scientists and entrepreneurs in Melbourne and Singapore
recently launched Human Mind Innovations (HMI), a consortium of businesses
and academic institutions that is developing emotionally intelligent
computers. HMI is creating and commercializing a patent for a method and
system for monitoring emotional state changes. The consortium wants to
challenge the perception that computers may be fast and smart but they will
never be able to compensate for a lack of consciousness. HMI claims that
computers with data compression systems, business savvy, and highly-refined
emotional intelligence will be able to change the way we live and how we do
business. The technology in HMI's computers merges a variety of
cross-disciplinary techniques from psychology, management, soft computing,
video and image processing, and other fields to capture and analyze the
subtle changes the human face presents in various behavioral situations.
The computers will give users direct feedback on changing emotional states
by reading the user's body language and facial expressions. "What we're
trying to do is humanize the technology," says La Trobe University
professor Rajiv Khosla. "We want to develop emotionally intelligent ICTs
(information and communication technologies) that interact in a human-like
manner with people."

Aiming for a Petaflop
eWeek (05/19/08) Vol. 25, No. 16, P. 20; Ferguson, Scott
IBM's $100 million Roadrunner supercomputer will likely offer a sustained
performance of 1 petaflop through a combination of new and commodity
technology, says IBM engineer Donald Grice. Roadrunner will employ Cell
processors developed by IBM, Sony, and Toshiba as accelerators for the
parts of applications that carry a heavy computing load, while standard x86
Opteron processors from Advanced Micro Devices will handle the standard
computing. In addition, the Roadrunner will operate exclusively on the
Fedora Linux operating system from Red Hat. This hybrid architecture lets
IBM build a system that consumes less power while boosting its ability to
scale to a petaflop and higher. Illuminata analyst Gordon Haff says the
project reflects a trend within high performance computing to migrate to a
heterogeneous framework that combines chips to accelerate different tasks.
"The really hard part here is the software, because we don't have very good
programming models to handle heterogeneous processing, but the
supercomputers, high-performance computing folks, particularly at the
extreme high end, are much more tolerant of programming difficulty given
the type of performance they need," he says. Roadrunner will be installed
at the U.S. Department of Energy's Los Alamos National Laboratory.
