Tests in Ohio Point to E-Voting Insecurities
Computerworld (12/31/07) Weiss, Todd R.
Recent tests of Ohio's electronic voting systems exposed security
shortcomings that are a continuing danger to the accuracy of elections,
concludes a report released by Ohio Secretary of State Jennifer Brunner.
The report recommends several steps to minimize those threats, including
centralizing the electronic voting counting and no longer using
touch-screen voting machines. "These findings do not lend themselves to
sustained or increased confidence in Ohio's voting system," Brunner writes
in the report, noting that the e-voting machines "do not meet computer
industry security standards and are susceptible to breaches of security
that may jeopardize the integrity of the voting process." Johns Hopkins
University computer science professor Avi Rubin, who heads the e-voting
activist group ACCURATE, says that Ohio's security problems are so severe
that it is not surprising they are trying to eliminate touch-screen
machines. "I don't think it's impossible to build high-tech voting
systems," Rubin says. "But it will require a lot more quality control and
effort than we've seen so far."

Electronic Passports Raise Privacy Issues
Washington Post (01/01/08) P. A6; Nakashima, Ellen
U.S. citizens that travel frequently between the U.S. and Canada or the
Caribbean will soon be offered RFID-embedded passports that can be read
from 20 feet away. The cards are intended to be more convenient for
travelers but create security and privacy concerns due to the possibility
of data being intercepted. The RFID passport card costs $45 and cannot be
used for air travel, and citizens have the option of a $97 card that is
more secure and can only be read at a distance of three inches. "The
government is fundamentally weakening border security and privacy for
passport holders in order to get people through the lines faster," says
Center for Democracy and Technology deputy director Ari Schwartz. Schwartz
says the problem with using RFID for identification is that the technology
was not designed to be secure or to track people, it was designed to track
goods during shipping. The government says the chip will contain a unique
identifying number linked to information in a secure government database
but not to names, Social Security numbers, or any other personal
information. The card will also come with a protective sleeve to prevent
hackers from scanning data wirelessly. Schwartz says a reader with a
strong battery could detect the chip's signal from as far as 40 feet away,
and that the chip could easily be reproduced to fool a border agent. Last
year, the Government Accountability Office reviewed technology similar to
that being used in the passport cards and reported that the technology
should only be used to track goods, not to identify people. The State
Departments wants to being issuing the passport cards this spring.

Fewer Women Choosing Computer Science Careers
Orlando Sentinel (FL) (01/01/08) Kelly, Kumari
Fewer women are choosing professional computer-related careers, and the
number of women in computer-science graduate programs has dropped to its
lowest level in nearly a decade. Between 2000 and 2005, the number of
women choosing computer science as an undergraduate major fell nearly 70
percent nationwide. "For most girls, it may indeed be intimidating to walk
into a class of 40 people and see one other girl in the room," says
University of Central Florida student Chistie Lo. "I've had classes where
I was the only woman in the room." Women have been steadily leaving
computer science-related careers since the 1990s, and gender gaps in some
technology-driven careers such as electrical engineering continue to widen.
Women account for 51 percent of workers in professional occupations in the
United States, but only 26 percent of IT professionals. In 1996, women
accounted for 41 percent of IT managers, but by 2006 that number was down
to 26 percent. The government and other experts say that efforts to
attract more girls to mathematics and science-related fields, and to
provide more mentoring for women already working is such fields, are
already having positive effects. "There is all kinds of research to show
that when you have a diverse work force, you get innovative ideas really
directed at the needs of consumers," says Compel Consulting President
Patricia Shafer, who authored a 2007 report titled "Women in Technology
2007." Shafer's report found that about 75 percent of women in technology
liked their jobs, but 48 percent felt there was inequality that favored men
and only 27 percent had mentoring programs at their company.

Q&A: Author Nicholas Carr on the Terrifying Future of
Computing
Wired News (12/20/07) Reiss, Spencer
Nicholas Carr's new book, "The Big Switch," examines the emerging "World
Wide Computer," or the network of dummy PCs linked to massive server farms
in the data cloud. Carr sees the future of computing as troublesome
because he anticipates all computers will be linked into essentially a
single computer, largely eliminating privacy. Carr says that most people
have already made the switch from desktop to cloud computing, with
increasing numbers of people using Web applications such as Flickr and
Gmail instead of traditional programs on their hard drives, and many people
made the switch without even knowing it. "People say they're nervous about
storing personal info online, but they do it all the time, sacrificing
privacy to save time and money," Carr says. "Companies are no different.
The two most popular Web-based business applications right now are for
managing payroll and customer accounts--some of the most sensitive
information companies have." Carr argues that although computers are a
liberating technology, they can also be a controlling technology. He says
that "as systems become more centralized--as personal data becomes more
exposed and data-mining software grows in sophistication--the interests of
control will gain the upper hand. If you're looking to monitor and
manipulate people, you couldn't design a better machine." Carr says the
scariest thing about the future is not that computers are starting to act
more human, but that humans are starting to act more like machines,
focusing more on the speed of locating and reading data. "We're
transferring our intelligence into the machine, and the machine is
transferring its way of thinking into us," Carr says.

Cyclists' Cellphones Help Monitor Air Pollution
New Scientist (01/02/08) Simonite, Tom
The MESSAGE research project in Cambridge, U.K., is using bike couriers to
monitor air pollution by collecting and sending data through a small
wireless pollution sensor with customized software attached to the bike.
"Mobiles are everywhere, and now have a lot of computing power," says
Cambridge University computer scientist Eiman Kanjo, head of technical
development for the project. "They can provide an alternative to expensive
custom hardware and report from places that otherwise aren't monitored."
The couriers are outfitted with air-pollution sensors and GPS units that
connect to their cell phones via Bluetooth. Customized software allows the
phones to constantly report the air quality and location to servers in the
lab. "They cycle around the city as usual and we receive the data over the
cell phone network," Kanjo says. "We can find out what pollutants people
are exposed to and where." The sensors are kept in storage containers on
the bikes and record levels of carbon monoxide, nitrogen oxide, and
nitrogen dioxide. Following initial trials, the sensors were made smaller,
more accurate, and capable of detecting carbon dioxide. Eventually, it may
be possible to combine the GPS unit with the sensor in a single device, or
to use phones with GPS capabilities, but currently phones are not accurate
enough.

MIT Students Power Supercomputer with Bicycles
Computerworld (12/19/07) Gaudin, Sharon
A group of cyclists from MIT powered a supercomputer for nearly 20 minutes
by pedaling, marking the largest human-powered computation in history. The
supercomputer, a SiCortex SC648 supercomputer, was calculating research on
nuclear fusion, and drew 1.2 kilowatts of energy. According to the
researchers, a conventional supercomputer could require 10 times the power
to run the same program. SiCortex is a Maynard, Mass.-based company that
focuses on energy-efficient supercomputing. A spokesperson from the event
says the human-powered session produced more computations than took place
in the first 3,000 years of civilization, and that more arithmetic
calculations were performed than were done before 1960. The MIT team was
highlighting the need for sustainable energy supplies, as well as competing
for the Guinness World Record, and for prizes in a bike company-sponsored
competition called "Innovate or Die," in which contestants use bike power
in innovative ways and post their submission on YouTube.

The U.S. Could Lose Top Talent
Christian Science Monitor (12/31/07) P. 9; Barrett, Craig
The European Union's "Blue Card" proposal could enable the next Silicon
Valley to emerge in Europe, writes Intel Chairman Craig Barrett. In
October, EU officials proposed creating a temporary but renewable two-year
visa, with a streamlined application process that would allow highly
educated foreigners to begin new jobs within one to three months. While
Europe is sending the message that it wants to attract the world's top
talent to bring innovation to its markets, U.S. officials are still bogged
down by immigration issues. The United States offers the H-1B visa and
employment-based (EB) green card programs, but they have severe shortage
problems as well as inflexible country quotas that might leave
professionals from China and India in limbo for five to 10 years, which
would hurt their opportunities for promotions and raises. Many
foreign-born professionals who have lived in the United States for years
and have graduated from American universities are now looking to explore
opportunities elsewhere. Barrett says U.S. companies depend on
foreign-born scientists and engineers to stay competitive, considering
foreigners already account for more than half of the nation's engineering
master's students and Ph.D. recipients.

The Library of Congress in Your Wrist Watch?
University of California, Riverside (12/20/07) Lovekin, Kris
University of California, Riverside professor Sakhrat Khizroev is
researching lasers that could eventually lead to a 10-terabit hard drive
only one-square-inch in size, 50 times the data density of today's magnetic
storage technology. Khizroev, along with University of Houston professor
Dmitri Litvinov, has developed a nanolaser that can concentrate light as
small as 30 nanometers, which is molecular in size for many substances.
The nanolaser can also focus 250 nanowatts of power, enough to ensure
effective information storage. The next objective is to refine the
nanolaser to produce light beams as small as five or 10 nanometers. The
technology used to manufacture the nanolasers was adapted by Khizroev's lab
from technology commonly used in semiconductor manufacturing diagnostics.
Khizroev says there are still several challenges, including lubricating
tiny parts and integrating the nanolaser with a recording head, but he says
the 10-terabit hard drive will be a near-term innovation, perhaps in as
little as two years. Long term, Khizroev says the use of photochromatic
proteins with nanolasers should help create nanocomputers capable of
storing increasingly large amounts of data in smaller places, and proteins
paired with nanolasers should also impact energy harvesting and a variety
of medical applications.

Technological Gadgets Smarten Up
Wall Street Journal (12/31/07) P. B3; Charny, Ben
Improvements in software and the development of more-powerful chips has
led to the reinvention of devices that were once considered "dumb," such as
the TV remote or personal navigator. New, smaller, more-powerful chips
will have the most immediate impact on the design of the latest navigation
systems, handsets, cell phones, and televisions. The change can most
easily be seen in personal navigation devices. Two years ago, they were
dumb devices with black and white screens with a functionality limited to
giving directions. Now, navigation devices can read out the names of
streets and find nearby attractions. Some even come with walkie-talkie
radios, play music and videos, and even answer cell phone calls. "Wait
till we see the first hardware to combine digital television and navigation
devices," says Nav N Go CEO Leon van de Pas. "If you have a navigation
device in you car, kids will be able to use it to watch high-definition TV
or play a game on it. With these things, you don't need to buy personal
digital assistants or car DVD players anymore." Televisions are also being
upgraded with broadband capabilities so people can incorporate their TV
into the local network and view Internet content directly on their
television.

Companies May Have Found a Way Around H-1B Visa
Limits
InfoWorld (12/28/07) Snyder, Bill
Advocates of American tech workers say companies are using L-1 visas to
bring in workers to do jobs for low pay. The L-1 visa program is designed
to allow multinational companies to transfer foreign managers and
specialists to their offices in the United States for a limited period of
time. While tech companies continue to complain that the 65,000-cap on the
H-1B visa program prevents them from finding enough highly-skilled workers,
the number of L-1 visas issued has averaged 315,000 over the last three
years. Immigration records show that 14 of the 20 companies that have the
most employees with L-1 visas are offshore outsourcing firms. India's Tata
Consultancy had the most with 4,887 L-1s in fiscal 2006, and had 3,601 in
fiscal 2007 to trail only Cognizant, a U.S.-based outsourcer with a major
presence in India that had 4,869. "I find it hard to believe that any one
company has that many individuals ... legitimately being transferred within
a single year," Sen. Richard Durbin (D-Ill.) said earlier this year during
a debate on immigration reform in Congress. When the 20,000 foreign
workers who receive advanced degrees from U.S. universities are also
counted, the total number of visas issued to highly-skilled workers each
year is about 400,000, according to the federal Citizenship and Immigration
Services (CIS) agency.

Boston Public Library to Put Historical Documents
Online
InformationWeek (12/27/07) Gardner, W. David
A group of nonprofit library and archival organizations is digitizing
books and historical documents from the 19-member Boston Library
Consortium, which includes the 3,700-volume personal library of U.S.
President John Adams. A variety of organizations and benefactors are
supporting library digitization projects including Public.Resource.Org, the
Internet Archive, the Alfred P. Sloan Foundation, and the Open Content
Alliance. "Unlike corporate-backed efforts by Google, Microsoft, Amazon,
et al, which all impose different, albeit understandable, levels of
restriction to protect their investment the [Boston Library Consortium] has
shown libraries all across the country the right way to take institutional
responsibility and manage this historic transition to a universal digital
archive that serves the needs of scholars, researchers, and the general
public without compromise," says the Sloan Foundation's Doron Weber. The
Boston Library Consortium has partnered with the Open Content Alliance to
establish the Northeast Regional Scanning Center at the Boston Library,
hosted by the Internet Archive, which will make scanned material available
to be indexed by any search engine. Members of the consortium include
Boston College, Boston University, Brandeis University, Brown University,
the University of Massachusetts, Wellesley College, and Williams
College.

Human Factors Researchers Test Voting Systems for Seniors
That Can Improve Accuracy and Speed for Voters of All Ages
Human Factors and Ergonomics Society (12/20/07)
Florida State University human factors researchers Tiffany Jastrzembski
and Neil Charness have identified ways to improve electronic voting
accuracy among older voters while simultaneously reducing waiting time at
polls. The researchers tested ballot and machine usability with a focus on
older voters, who because of reduced vision and motor control can have a
more difficult time using computers, particularly in a time-sensitive
situation. Two subject groups, ages 18 to 26 years old and 64 to 77 years
old, tested four ballot layouts and machine designs, including a
touchscreen machine with a full ballot on a single screen, a touchscreen
with one ballot per screen, a touchscreen and keypad with a full ballot,
and a touchscreen and keypad with a single ballot. The touchscreen with a
single ballot per screen produced the most accurate results, but the pure
touchscreen with a full ballot had the fastest completion times.
Jastrzembski and Charness recommend additional studies with older voters,
which could lead to more user-friendly machines and ballots for users of
all ages.

EU Project Develops Affective Interface Technologies for
New Media
Cordis News Service (12/20/07)
An EU-funded project has made some key advances in the design of human
computer interfaces. Conveying Affectiveness in Leading-Edge Living
Adaptive Systems (CALLAS), named after the Greek opera singer Maria Callas,
is a project that seeks to develop new multi-model affective interfaces for
the new media, digital arts, and entertainment fields by integrating
emotional models from a wide range of emotions. The models will be based
on the facial characteristics and expressions of spectators during
communications, and they will help improve the experience of the final
users. The project is looking to use the fundamental role of emotions in
conditioning communication between two people to improve interaction
between people and machines. The affective interfaces of CALLAS will focus
on the key role of new media experiences in digital theater, interactive
TV, augmented reality art, and interactive public performances.

Computer Terrorism Becomes a Concern
Patriot-News (PA) (12/25/07) Lenton, Garry
Malware infiltration, no matter how minor, is a cause for concern among
computer security experts across the United States. In September the
Government Accountability Office issued a report warning that the computer
systems responsible for running the nation's infrastructure are
increasingly vulnerable to hackers, and their disruption could seriously
affect the national economy. In theory, electric service to a city or a
region could be shut down by attackers who exploit poorly shielded home
computers across the country. "If everybody who had a home computer would
simply enable a firewall and make sure antivirus software was in place and
put anti-spam components in their system, there would be a significant drop
in what we see," argues chief information security officer for Pennsylvania
Robert Maley, whose office impedes 25,000 viruses, 10 million attempts to
penetrate firewalls, and 80 million spam emails every month on average.
Hackers are now motivated to compromise systems for profit rather than for
bragging rights, and there are criminal gangs in Russia and eastern Europe
that offer hacking services, according to Maley. Lehigh University
professor Dr. Mooi Choo Chuah notes that initiatives to enhance the
security of government-controlled systems are gaining traction, but she
thinks a greater effort to secure business systems that depend on Internet
connections is required. Deputy director of reactor security at the
Nuclear Regulatory Commission Scott Morris says the increasing reliance on
digital information has been accompanied by the growing importance of
security.

Bible Put on a Pinhead-Size Chip
BBC News (12/24/07)
Researchers in Israel have put the Bible on a miniscule chip in an attempt
to get young students interested in nanoscience and nanotechnology.
Technion researchers used a device called Focused Ion Beam to write the
nano-Bible on a silicon surface at the Haifa Institute of Technology. The
nano-Bible consists of 300,000 words in Hebrew, and it is covered with a
thin layer of gold. The researchers also have plans to photograph the
Bible and display it on a giant wall within the Faculty of Physics. "In
this picture, which will be 7 m by 7 m [23 ft by 23 ft], it will be
possible to read the entire Bible with the naked eye," says Ohad Zohar, one
of the project's managers at Technion. "Near this picture, the
original--the nano-Bible itself, which is the size a grain of sugar--will
be displayed."

Move Over Silicon: Advances Pave Way for Powerful
Carbon-Based Electronics
Princeton University (12/20/07) Schultz, Steven
Princeton engineers have developed a way of replacing silicon with carbon
on large services, which may lead to faster, more powerful cell phones,
computers, and electronics. Silicon is largely believed to have reached
its limit in the computing industry and graphene, a single layer of carbon
atoms arranged in a honeycomb lattice, could allow electronics to process
information and produce radio transmissions 10 times better than
silicon-based devices, according to Princeton professor Stephen Chou.
Until now, switching from silicon to carbon was not possible because
technologies believed they needed graphene material in the same form as the
silicon used to make chips, a single crystal of material eight or 12 inches
wide. The largest single-crystal graphene sheets are no more than a couple
of millimeters wide. Chou and his researchers realized that large graphene
wafers are not necessary as long as they can place small crystals of
graphene only in the active areas of the chip. The researchers developed a
way of doing this and created working, high-performance graphene
transistors as a demonstration. The method uses a special stamp consisting
of an array of tiny flat-toped pillars, each one-tenth of a millimeter
wide. The pillars are pressed against a block of graphite, which sticks to
the pillars. The stamp is removed, peeling away a few atomic layers of
graphene. The stamp is then aligned and pressed against a larger wafer,
leaving the graphene exactly where the transistors will be built. Chou
says the technique is like printing, and can be repeated using a variety of
shaped stamps to cover all active areas with single crystals of graphene.
The graphene transistors used in the demonstration were more than 10 times
faster than silicon transistors in moving "electronic holes," a key speed
measurement. Chou says the technique could find almost immediate use in
radio electronics, such as cell phones and other wireless devices, and
depending on the level of interest from industry, could be applied to
wireless communication devices within a few years.

The Archiving Tsunami
Government Computer News (12/10/07) Vol. 26, No. 30, Wash, Mike
Government Printing Office chief information officer Mike Wash predicts
that the GPO will have more than 1 petabyte of accessible content to
maintain and manage within the next 10 years. As publications shift to
multimedia formats that include audio and video, content size will grow
considerably larger, and Web-based services including wikis, blogs, and
other collaborative tools will make capturing and archiving the work of the
government increasingly difficult. Creating content and access models
based on historical trends and anticipated shifts in the industry or
markets can help prepare for these expanding volumes, and although
predictive models are inevitably wrong, thinking about them can lead to
better strategies and solutions. Monolithic computing infrastructures will
rapidly become unwieldy and difficult to maintain. However, cloud
computing, which stores user data in the Internet cloud and utilizes
Web-based applications, and the virtualization of computing systems, will
make it easier for computation to be coordinated and distributed, which
will support advanced search, data parsing for digitized content,
cataloging, and other computational work.

Bit by Bit, Home Computers Aid Science
Chicago Tribune (12/25/07) Manier, Jeremy
Eight years ago the California-based SETI Institute created the idea of
embedding software in home PC owners' screen savers to help search through
radio noise for possible signals from alien civilizations. Since then,
some 40 research groups have created projects based on the same principle,
using a network of personal home computers to help solve complex problems,
and now hundreds of thousands of computers are exploring how proteins fold,
searching for new prime numbers, and simulating climate change. By
creating a network of home computers over the Internet, researchers can
access supercomputer-like processing power at a fraction of the cost,
cutting the lag time of some calculations from years to days. A project
examining how proteins fold called Folding@home is one the largest group
efforts, with about 250,000 computers at any given moment, and attracts a
large number of video game enthusiasts with PlayStation 3 consoles, which
have a speedy graphics processor. Participants normally have a
pre-existing interest in the project's subject matter and consider the use
of their computer a valuable donation to science. "This is democratic
computing, so it's based on the goodwill of a bunch of people from all
walks of life, all backgrounds," says University of Illinois
Urbana-Champaign physics professor Benjamin Wandelt, director of the
Cosmology@home project.

A Conversation With Mary Lou Jepsen
Queue (12/07) Vol. 5, No. 7, P. 9; Ryan, John
CTO of the One Laptop Per Child (OLPC) project Mary Lou Jepsen and her
team tackled numerous design challenges in developing a highly inexpensive,
rugged laptop that incorporates extremely low-power electronics, mesh
networking, and a display that is readable in sunlight, which was Jepsen's
personal contribution. She says in an interview that designing the machine
from the display onward has allowed the creation of an entirely new kind of
architecture that can be applied to low-cost as well as high-end laptops.
The laptop is designed to endure extreme heat and other harsh climate
conditions partly by being so low powered, and the mesh networking
component establishes an Internet connection, which dovetails with the
project's goal of making computers and the Internet accessible to children
in poverty-stricken Third World countries so that their education can be
substantially improved. Reducing power consumption involves the
replacement of the hard disk with flash memory, while Jepsen notes that
memory is embedded directly within the display, allowing the screen to
remain on while the rest of the motherboard or chipset is deactivated. She
says the laptop's user interface "explicitly enables collaboration," which
is a key advantage in developing countries where lack of money and
resources makes dull and uninspiring rote learning the norm. Jepsen says
the laptop her team has designed is very environmentally friendly by virtue
of its power efficiency, its five-year lifetime, a lack of toxic materials,
and significant weight and size reduction in comparison to typical laptop
models. She says the machine's display features a luminance channel that
is three times the chrominance channel, which supports sunlight readability
and can aid in the reading of e-books.
