Coming Together to Help Grow the Next Generation of
Computing Leaders
National Science Foundation (03/26/08)
Rice University professor Richard Tapia says many minority students
enrolled in undergraduate computer science programs at top-tier research
universities feel isolated and unsupported. As a result, Tapia says, many
leave the field to pursue different majors in more welcoming degree
programs where they feel they have support and a high probability of
success. Tapia and colleagues from nearly a dozen universities are
collaborating with private industry and other groups, including ACM, to
provide support and to prevent what Tapia calls the "loss of the precious
few" minority students majoring in computer science. Tapia serves as the
director of the Empowering Leadership (EL) Alliance, an organization that
aims to provide minority students with a community of support as they
pursue their degrees. "At the nation's top institutions, there are many
choices inside and outside the university environment that offer vibrant
opportunities and a welcoming environment," Tapia says. "We aim to provide
both within the computing disciplines." In October, students from around
the country met in Orlando for the Richard Tapia Celebration of Diversity
in Computing conference, where they were able to interact with national
leaders in computing from the academic and business sectors. The EL
Alliance also has an online mentoring group that connects undergraduate and
graduate students with national leaders in computing who can offer
expertise and advice as students progress through their academic
careers.

H-1B Backers Seek White House Help for Foreign
Students
Computerworld (03/27/08) Thibodeau, Patrick
H-1B visa supporters are asking the Bush administration to extend the time
that foreign graduates can work on student visas from one year to 29
months. The proposed action is a stop-gap plan that would not increase the
federal government's cap on H-1B visas, but would make more workers
available to technology companies. Increasing the amount of time a foreign
graduate could work in the United States, through a program called Optional
Practical Training, would give students a better chance of getting H-1B
visas, and the changes can be made without legislative action. Supporters
of the plan have been urging the Department of Homeland Security to approve
the extension. Other efforts to increase the number of foreign workers
eligible to work in the United States include convincing Congress to
release H-1B visas that were authorized by lawmakers in previous years but
not used, which could provide an additional 300,000 visas. Victor Johnson
of NAFSA, a Washington-based association that promotes international
education, says that for universities to succeed in attracting foreign
students, the United States needs to have a supportive climate that
includes H-1B visa reform.

Yahoo Is Joining an Alliance That Has Google as
Leader
New York Times (03/26/08) P. C7; Helft, Miguel
Google, MySpace, and Yahoo are forming the OpenSocial Foundation, a
nonprofit organization that will develop standards for programmers to use
to create applications that can run on any social network or Web site that
wants them. Analysts say Google originally formed the OpenSocial alliance
last fall in response to the growing popularity of Facebook, which has
attracted thousands of outside developers who create programs for the site
and that has significantly contributed to Facebook's popularity. Although
Facebook is not part of the OpenSocial Foundation, several Facebook
application developers say they will make their programs compatible with
the new standard. Google and Yahoo says the foundation will "ensure the
neutrality and longevity of OpenSocial as an open, community-governed
specification for building social applications across the Web." The
OpenSocial Foundation will launch within the next three months.

Foldable, Stretchable Circuits
Technology Review (03/28/08) Greene, Kate
University of Illinois Urbana Champaign and Northwestern University
researchers have demonstrated that it is possible to use ultrathin silicon
to build sheets of foldable and stretchable circuits. Manufactured from
thin sheets of silicon on plastic or rubber, the bendable circuits could
lead to devices such as wearable computers and implantible health
monitoring systems. Illinois professor John Rogers says the entire
thickness of the circuit is 1.5 microns. It is the thinness of the circuit
that makes it naturally bendable. The researchers developed two types of
chips. The first is foldable, but to ensure the circuit would work
regardless of how it was twisted or bent, the researchers placed the
silicon, or whatever part of the circuit is most fragile, at a distance
between the top and bottom of the circuit sheet that experienced the least
amount of strain. Proper placement optimizes the electronics and enables
them to work as if they were on a solid wafer. The second circuit was made
by optimizing circuit sheets and bonding them to prestretched rubber that
was extended in both directions. When the rubber was allowed to relax, the
silicon layer bucked in a complex, wavy pattern. The researchers are able
to locate positions on the circuit where the wavy structure will form when
the rubber is released, Rogers says, allowing them to chose the locations
so they do not overlap any fragile or strain-sensitive components of the
circuit.

Americans Still Wary of Voting Machines for 2008
Agence France Presse (03/23/08)
Despite the growing use of computers in elections in the United States,
many jurisdictions are reconsidering their voting technology amid growing
concerns that the systems are vulnerable to software and hardware glitches,
manipulation by hackers, and a variety of other problems. Five states that
had revamped their voting systems after 2000 are undertaking a second
overhaul because of their discontent over electronic machines, according to
the Pew Center on the States. About 80 percent of the votes cast in the
U.S. include the use of computers, and about 38 percent use direct
recording electronic (DRE) voting machines, reveals a study by the
University of Iowa's John McCormally. Many DRE machines do not leave a
paper trail, which makes recounts or audits impossible. Computer scientist
Alan Dechert, who heads the Open Voting Consortium, says paperless
touch-screen voting systems have failed in numerous cases. Verified Voting
Foundation project director Warren Stewart says the growing doubts over the
reliability of paperless systems could be problematic during the 2008
presidential election. Stewart says it is highly probable that the
election could come down to one state where a situation cannot be resolved
because of an inability to recount electronic vote tallies. He says the
most reliable systems are optical-scan devices in which voters mark their
choice on paper ballots that are then read and tallied by computerized
scanners.

How to Succeed in the High-Tech Boys' Club
InfoWorld (03/25/08) Schwartz, Ephraim
The number of incoming undergraduate women choosing to major in computer
science fell 70 percent between 2000 and 2005, according to the National
Center for Women & Information Technology (NCWIT). Stanford University
professor Shelley Correll concludes in a study that women often judge their
own skills very harshly in an effort to combat gender stereotypes, and
NCWIT CEO Lucy Sanders and VoiceObjects CEO Beatriz Infante agree that
women must be heavily encouraged to overcome their anxieties about their
abilities and pursue senior leadership positions. Consultant Susan Major
says women must walk a tightrope between coming off as too aggressive or
too soft, and believes changing business culture to emphasize teamwork and
collaboration would be very beneficial to women. Infante suggests that
women should not be afraid to wield power like male executives and display
an aggressive approach to business as men do, arguing that the
self-confidence such behavior exhibits would work in their favor and
enhance their credibility as leaders. LSI CTO Claudine Simson says the
shrinking enrollment of females in high-tech may be attributed to the
discouragement they feel at the prospect of working in a field
characterized by long hours and economic instability, as well as the stress
this may place on their desire to fulfill their family responsibilities.
"The image of computing is still a white geeky guy sitting by a terminal
eating junk food," Simson says, adding that women need to be made aware
that computing requires a broader range of skills than just programming.

Inspiring Girls to Tech
SiliconValley.com (03/26/08) Antonucci, Mike
Microsoft held a DigiGirlz tech camp Tuesday at its campus in Mountain
View, Calif. The one-day event gave the 70 or so high-school girls in
attendance a chance to learn more about career opportunities in technology.
The young girls were impressed by the positive attitudes of the women who
discussed their careers during a morning panel, and California CIO Teri
Takai followed up with an afternoon talk on gaining confidence and
empowerment. The tech camp also gave the girls an opportunity to obtain
instruction on building Web pages, maintaining privacy and data security
online, using the Internet on cell phones, and other techniques and
practices. For Microsoft, the event is an acknowledgment that there are
not enough women in computer science and software engineering, and in
executive technology positions. "The technology universe is definitely
male-dominated," said panelist Veronica Belmont, who hosts and produces the
Web show "Mahalo Daily" for Mahalo.com. Microsoft will offer DigiGirlz
camps in about two dozen cities through August.

Carbon Could Enable Fastest Chips
EE Times (03/25/08) Johnson, R. Colin
University of Maryland researchers say carbon-based transistors could
outperform the fastest chip materials, including indium antimonide. The
researchers recently characterized graphene monolayers, sheets of pure
carbon one atom thick, and found that graphene-based transistors appear to
be able to achieve their maximum speed at room temperature. The
researchers measured the electron mobility of graphene monolayers between
50 Kelvin and 500 Kelvin and found the electron mobility to be about 15,000
cm2,Vs regardless of temperature. "What we now think is that phonon
scattering of electrons in graphene is very weak, and that leads us to
believe that we are being limited by impurities," says team leader Michael
Fuhrer. "If we can remove those impurities, we think we can achieve
electron mobilities of 200,000 cm2/Vs at room temperature--which is more
than 100 times better than silicon." To achieve the highest possible
mobility, the silicon dioxide substrate needs to be removed. The
researchers are considering switching to silicon carbide, diamond, or
removing the substrate completely and using air gaps beneath graphene
transistor channels.

Professor: Computers Plus People Equals Risk
IDG News Service (03/27/08) Kirk, Jeremy
London School of Economics professor of information systems Ian O. Angell
says companies are relying too much on technology to run their business, a
dangerous practice given technology's inability to account for
unpredictable situations. Angell says the problem is that business
information systems make assumptions that do not necessarily match up with
real-world events. Those assumptions are then used to make decisions,
which leads to false conclusions. "When companies use the tools of
technology to solve a problem, they may or may not succeed, but what is
certain is that completely unexpected phenomena happen," Angell says. The
conclusions made by computers are only as good as the numbers people put
into them, which can often be altered or misleading, he says. People now
automatically believe whatever they see on the screen, which Angell calls a
"glass cockpit effect." He believes that digital security needs to be
redefined, and notes that the marginal events that lead to larger security
problems are only noticed in hindsight.

UCSC Computer Scientist Phokion Kolaitis Earns
'Test-of-Time' Award
University of California, Santa Cruz (03/26/08) Stephens, Tim
ACM's Symposium on Principles of Database Systems (PODS) has awarded its
first Alberto O. Mendelzon Test-of-Time Award to ACM Fellow Phokion
Kolaitis, a professor of computer science at the University of California,
Santa Cruz's Baskin School of Engineering. ACM PODS recognized Kolaitis
for his 1998 paper "Conjunctive-query containment and constraint
satisfaction," along with another paper published that year. The papers
had "the most impact (in terms of research, methodology, or transfer to
practice) over the intervening decade," according to the ACM PODS award
committee. Kolaitis co-authored the paper with Moshe Vardi, and it was
published in the Proceedings of PODS 1998. The paper discussed two key
challenges for databases and artificial intelligence, and offered a deep
complexity analysis. Kolaitis specializes in computer logic, database
theory, and computational complexity.

Phones With Feeling Are More Useful
New Scientist (03/24/08)
Stephen Brewster and colleagues at the University of Glasgow in the United
Kingdom consider tactile feedback to be key to making it easier to type on
touch-screen phones such as iPhone. Their approach to replicating the feel
of a keyboard is to create sophisticated sensations for buttons similar to
the way in which cell phones vibrate. For example, the team has used
software to create a single pulse 30 milliseconds long that gives the
feeling of a button being clicked. They have also created a
half-second-long buzz for when a finger has slid from one button to
another, and there is a "rough" feeling that tells the user they have
strayed to another key. Testing shows that typing speed and accuracy when
working with such haptics is closer to the use of a real keyboard. They
will discuss their research in April at the Computer Human Interaction
conference in Florence, Italy.

DSLs Lead Development Paradigm Shift
eWeek (03/26/08) Taft, Darryl K.
The software development community needs to move beyond its use of static,
procedural languages and frameworks and start using language-oriented
programming. ThoughtWorks senior application architect Neal Ford, speaking
at TheServerSide Java Symposium on March 26, says domain-specific languages
(DSL) are designed for specific tasks. Ford says ThoughtWorks colleague
Ola Bini envisions a future stack of basic programming tools consisting of
a "stable language" at the bottom level, with dynamic languages built on
top of that, and DSLs added at the top layer. Ford says that DSLs improve
the software development process by "eliminating noise," and that
programmers experienced in dynamic languages tend to build DSLs on top of
their low-level language. "Using DSLs evolves the way we build and use
frameworks, escalating our abstraction levels closer to the problem domains
and farther from implementation details," Ford says.

Eye-Controlled Robot May Make Heart Surgery Safer
Guardian Unlimited (UK) (03/22/08) Randerson, James
British researchers are developing software that will allow surgeons to
direct a medical robot with their eye movements. An eye-tracking device
that can precisely determine where a surgeon is looking is designed to work
with the software, which would then create a 3D map of an area of tissue
that is under observation. "What that does is it uses the surgeon's brain
as a way in to calculating the depth of the tissue," says Lord Darzi, a
surgeon who heads the Hamlyn Center for robotic surgery at Imperial College
London. The Hamlyn Center researchers are also working on "augmented
reality," which would allow surgeons to explore the surface of the tissue
to the structure they are operating on, and virtual "no-go zones" that
could help prevent surgeons from cutting a healthy blood vessel by mistake.
They are testing their work on the sophisticated Da Vinci robotic
surgeon.

Hello, Gorgeous! Meet the Laptop You'll Use in
2015
Computerworld (03/26/08) Nadel, Brian
Laptop design is expected to undergo significant changes over the next
seven years and move away from the current clamshell format, predicts
Intel's Mike Trainor and other experts. One futuristic notebook concept,
the Compenion, features a slide-up lid, a panel that doubles as a keyboard
and scribble pad, an 11-inch screen, and 0.75-inch thickness. V12 Design's
Canova eliminates the traditional display and mechanical keyboard in favor
of two touch-sensitive displays, and can alternate between sketchpad,
e-book, and piano keyboard functions depending on how it is held. The
Cario from independent designer Anna Lopez replaces the lid hinge with a
bar that serves as a carrying handle, and can be used on desks and in cars,
where it can be mounted on the steering wheel and project images onto the
windshield via a microprojector. The screenless Siafu device, which is
designed for visually impaired users, instantly renders images as
corresponding 3D shapes by using an oil-based synthetic material that is
reactive to electrical fields. New materials such as more rugged and
easily reparable plastics and more sophisticated peripherals are some of
the technological innovations driving the transformation of laptops.
Furthermore, tomorrow's laptops are expected to be smarter and capable of
more advanced tasks thanks to multicore processors; the replacement of the
CPU's front-side bus with an integrated controller that boosts the
efficiency of data distribution through faster operation; the expansion of
storage capacity and solid-state memory; sequential red, green, blue
backlighting that will eventually be succeeded by organic LEDs; and 3D
displays. A migration from lithium-ion cells that have to be built in
cylinders to lithium polymer cells that can come in assorted shapes and
sizes will take place, while inductive charging could greatly simplify
powering up the notebook.

NIST Unveils Tool to Foil Attacks via DNS
Government Computer News (03/25/08) Campbell, Dan
National Institute of Standards and Technology (NIST) network researchers
Scott Rose and Anastase Nakassis have written a paper that introduced a
method federal systems administrators can use to protect their systems from
the attacks launched over the Domain Name System (DNS). Rose and Nakassis
say that DNS security extensions (DNSSEC) that are originally meant to
protect DNS zone data contain an unintentional side effect that enables an
attack precursor known as "zone enumeration." Although zone enumeration is
possible without DNSSEC, the traditional methods of enabling zone
enumeration are often impractical because they use time-consuming or
processor-intensive brute force techniques that are often repelled by
intrusion detection systems. Rose and Nakassis also note that there are
several techniques that allow networks to realize the intended
authentication and integrity benefits of DNSSEC while simultaneously
"reducing DNS information leakage." Such techniques are important because
the need to protect network operations with methods offered by DNSSEC will
only increase as DNS becomes more and more important. In addition, the
techniques could improve DNSSEC authentication and integrity protection,
which would in turn protect DNS zones and stop attempts to compromise
data.

CS Gets With Parallel Program
EE Times (03/24/08)No. 1519, P. 1; Merritt, Rick
Mainstream computers will be unable to exploit performance gains from
next-generation multicore processors without an easy-to-use parallel
programming model, the provision of which will require one or more
milestones. Intel and Microsoft recently announced a five-year plan to
commit $20 million to underwrite work at new parallel computing labs at the
University of California, Berkeley and the University of Illinois at
Urbana-Champaign, concurrent with a nearly completed design for a
FPGA-based system whose purpose is to investigate parallel computing
concepts. The goal of the Berkeley Emulation Engine version 3 is to help
researchers rapidly prototype processors with hundreds or thousands of
cores and study new programming methodologies. Berkeley computer science
professor (and former ACM president) David Patterson believes graduate
courses must be changed to reflect the shift to parallel programming, while
undergraduates need to be informed about this trend. The first demo
vehicles for the Berkeley lab will probably stem from projects focusing on
image retrieval and parallel browser applications. The FPGA-based system
forms the nucleus of the multi-university Research Accelerator for Multiple
Processors program, which is part of a wide-ranging exploration of new ways
to build computers. "What I am hoping is things like [the FPGA-based
system] will revitalize research in computer architecture," says Microsoft
Research's Charles Thacker.
