Upstarts and Rabble Rousers
San Francisco Chronicle (03/20/06) P. E1; Abate, Tom
Tomorrow, Stanford University will honor its four decades' worth of
computer science pioneers and visionaries who have been integral to the
Silicon Valley economy, such as artificial intelligence expert John
McCarthy. ACM President David Patterson applauded Stanford's celebration
of its own, noting that the school deserves special recognition for being
the first to define computer science as a discipline and for its
longstanding tradition of practical research. "What sets Stanford apart is
the startup culture," said Patterson. "I have this sense that it's an
almost unwritten rule that you have to start a company to be a successful
professor at Stanford." At its "Upstarts and Rabble Rousers" panel,
Stanford will recognize alumni Andy Bechtolsheim, co-founder of Sun
Microsystems, and Jerry Yang, who co-founded Yahoo!. The event will also
recognize the creation of MIPS, Silicon Graphics, and Evite.com. Looking
to an earlier era, Stanford will recognize Pierluigi Zappacosta, who left
the university and went on to co-found Logitech in 1981. Stanford's event
will also feature presentations gazing into the future of technology, said
William Dally, chairman of the computer science department. Dally
envisions the unchecked migration of computers into more areas of people's
lives, intensifying the demand for computer scientists. He is frustrated
at the often reported perception that computer jobs are disappearing and
the image of the "Dilbert-like characters chained to their workstations all
day."

Verification Tools for Safe, Secure Software
AScribe Newswire (03/16/06)
ACM has named Robert S. Boyer, J Strother Moore, and Matt Kaufmann, all of
the University of Texas at Austin, the winners of its Software Systems
Award. Boyer, Moore, and Kauffman are the developers of the Boyer-Moore
Theorem Prover, a formal tool that computer scientists have used to verify
the safety and security of critical hardware and software. Such a tool is
helpful when dealing with applications such as embedded medical devices,
spacecraft and aircraft controls, and autonomous vehicles such as
self-driving cars. The award, which carries a $10,000 prize, was created
to honor institutions and individuals who have developed software systems
that have been influential over the years in their concepts and commercial
acceptance. According to the award citation, the latest version of the
tool, ACL2, is "the only simulation/verification system that provides a
standard modeling language and industrial strength model simulation in a
unified framework." Boyer is a professor in the Computer Sciences,
Mathematics, and Philosophy Departments; Moore holds the Admiral B.R. Inman
Centennial Chair in Computing Theory; and Kaufmann is a senior research
scientist. They will be honored at the annual ACM Awards Banquet on May
20, 2006, in San Francisco, Calif.

East Africa Technology Information Project Receives
Association for Computing Machinery Humanitarian Award
AScribe Newswire (03/16/06)
ACM has named the project leaders of the Nakuru Local Urban Observatory
(LUO) in Kenya as the winners of the 2005 Lawler Award for Humanitarian
Contributions. Albrecht Ehrensperger of the Center for Development and
Environment of the University of Berne, Switzerland, and Solomon Mbuguah
and Ernest Siva of the Municipal Council of Nakuru will receive the Eugene
L. Lawler Award for Humanitarian Contributions Within Computer Science and
Informatics during the annual ACM Awards Banquet, May 20, 2006, in San
Francisco. Through user-friendly software, the Nakuru LUO project has
provided its Kenyan community with a spatial information tool that is able
to store, retrieve, map, and analyze geographic data. The community, which
has never had data on sanitation, water supply, and other public facilities
before, is now able to use a global information system (GIS) for town
planning initiatives. The geographical information database, which can be
assessed at libraries, schools, and non-governmental agencies, also serves
as a tool for obtaining local news and other services. ACM introduced the
award, which includes a $5,000 prize, in 2000, and it is given every two
years.

FOSS Community, Disabled Users Must Learn to
Communicate
NewsForge (03/18/06) Fioretti, Marco
The International Organization for Standardization (ISO) has formulated
standards to guarantee that software is accessible to users with
disabilities. The free and open source software (FOSS) community has long
been hearing calls for accessibility assurances, particularly after
Massachusetts officials' announcement that the state would adopt OASIS
OpenDocument format drew criticism from advocates for the disabled.
OpenDocument is currently under an accessibility review, and
representatives from the Bay State Council for the Blind and the Disability
Policy Consortium have met with Massachusetts officials and FOSS
representatives. The meeting revealed the disconnect between the FOSS
community and disabled users, as FOSS representatives explained that an
accessibility infrastructure based around FOSS would create opportunities
for disabled workers in Unix system administration and Web site design, but
the disability advocates maintained that "without advanced training to
develop a qualified pool of talent, new hires for state government agencies
with OpenSource, OpenDocument platforms will be everybody but people with
disabilities because of perceived or real training requirements." While
attempting to install a new driver for a Braille terminal, Italian computer
science student Fabrizio Marini found that Linux is still too complicated
for novice users. Some disability advocates show no preference between
open and proprietary software formats, provided that user accessibility is
ensured. While the FOSS community has been bridging the gap with disabled
users, FOSS documentation still needs to be improved, and FOSS developers
would be well-advised to check in with disability groups when they launch a
major project.

Cray Plans Radical Product Design
Wall Street Journal (03/20/06) P. B4; Clark, Don
Cray today is expected to announce a redesign of its supercomputers that
will integrate blades into a conventional chassis, with software serving as
a hub, allocating the tasks to the various blades. Cray is best known for
its vector processing technology, which has garnered federal funding for
its applications in nuclear weapons design and code cracking, though
clustered systems have eroded the demand for specialized technologies such
as Cray's. With the performance increases of conventional processors
tapering off, Intel and AMD are investing heavily in multicore
technologies, though they are encountering limitations with passing data
over numerous chips. Others in the industry are using FPGAs to perform
high-speed calculations. The vertical organization of circuit boards in
servers is now catching on with supercomputers; SGI announced a blade
design in November for its Altix systems. Cray's adaptive-supercomputing
technology will transfer chores among blades powered by AMD Opteron chips,
FPGAs, or its Cray's own vector processors. "You get more bang for the
buck," said Cray CEO Peter Ungaro. "It's a very innovative idea."

RFID World Still Reacting Strongly to Virus
Research
TechWeb (03/16/06) Sullivan, Laurie
Some radio frequency identification (RFID) technology experts are taking
issue with a paper presented at the IEEE conference in Pisa, Italy, that
suggested RFID could spread computer viruses. A third-year PhD student
from Vrije Universiteti in Amsterdam, Melanie Rieback, created an
artificial virus for her paper, "Is Your Cat Infected With a Computer
Virus?" that suggested RFID tags have the potential to spread viruses
through readers into poorly written middleware applications and into
enterprise backend systems and databases. Kevin Ashton, vice president of
ThinkMagic and co-founder of the Massachusetts Institute of Technology
Auto-ID Center, says Rieback actually demonstrates a self-replicating piece
of SQL code, and not a virus, in the paper. RFID tags store numbers, and
are very unlikely to accept executable code via a virus. "The student
researchers think a database picks up the information from a tag and puts
it in the buffer, and that's not what happens," adds Gartner vice president
of research Jeff Woods. However, Woods says in theory the arguments for
buffer overflow, and software vulnerabilities could compromise RFID
systems. Moreover, some RFID experts say the industry should do a better
job of testing applications, while others say companies that deploy the
technology should make sure they secure the technology.

For Gates, a Visa Charge
Washington Post (03/19/06) P. B7; Broder, David S.
Microsoft Chairman Bill Gates made a rare trip to Washington, D.C., last
week to lobby for an increase in H-1B visa caps. H-1B visas have been
capped at 65,000 since 2003, and applicants must have specialized
knowledge, a job offer from a U.S. company, and a bachelor's degree to
qualify. The "high-skills immigration issue is by far the number one
thing" among Microsoft's interests in the upcoming legislative agenda,
Gates said. "This is gigantic for us." Sen. Arlen Specter (R-Penn.) has
been preparing a draft bill that would increase the H-1B cap to 115,000 and
exclude dependents from the cap, potentially increasing the flux of
immigrants to 300,000 a year. While these types of workers could be hired
in China or India for less money, Gates says that Microsoft, which conducts
85 percent of its research and development in the United States, prefers to
integrate its developers with its program managers and marketing team
rather than use overseas labor. President Bush is in favor of H-1B
increases, and Gates is pleased that math and science education in
secondary schools now enjoys bipartisan support to boost the number of
Americans qualified for these specialized jobs. Of greater concern is the
movement in the House to close off U.S. borders that seems unable to
distinguish between the problem of illegal immigration at large and visas
for highly specialized workers.

Judge Grants Google a Reprieve
Wall Street Journal (03/20/06) P. B4
U.S. District Judge James Ware ordered Google on Friday to provide 50,000
randomly selected address for Web sites from its databases. However, the
judge also ruled that Google does not have to hand over information
regarding consumer Web-search queries to the Justice Department. Judge
Ware felt that if Google handed over the queries to the Justice Department
that they would lose the trust of some of their users. "This is a clear
victory for our users," said Google in a statement. The Justice Department
wanted to use the information from Google to defend the Child Online
Protection Act. "The next time the government comes calling, it will pile
so much more on its side of the scale, a better explanation of its need and
a more compelling set of facts that the court will have no choice but to
compel Google to turn over search queries," says Paul Ohm, an associate
professor at the University of Colorado School of Law. Some experts agree
that government requests may actually be granted in the future.

Student Entrepreneurs: New Sensor Will Help Guarantee
Freshness
University of Florida News (03/15/06) Hoover, Aaron
Six engineering students at the University of Florida have developed a
prototype of a smart sensor that will allow retailers to determine at what
point in shipping products spoil, when they will spoil, and who is
responsible when spoilage occurs. The new sensor, which is the size of a
half-dollar, was designed by a team led by Bill Eisenstadt, an associate
professor of electrical and computer engineering, to track and interpret
temperature, humidity, and the shock of a product being dropped, among a
host of other variables. For example, the device monitors the temperature
of a product by combining its readings with an algorithm that is
electronically tuned to the rate at which fish, milk, flowers, or any other
product spoils. The sensor records and wirelessly transmits the
information to retailers, which are able to check from a laptop computer if
the product is fresh, how long it has until it spoils, and at what point
temperatures rose above normal during shipping. "We think this sensor will
make the supply chain both safer and more efficient," says Bruce Welt, an
assistant professor of agricultural and biological engineering who serves
as a faculty advisor for the project. "Hopefully, that will translate into
lower cost, better quality products for consumers." Drug makers are among
the industries that could benefit from the sensor. The engineering team
has filed a patent for the sensor, and is receiving assistance from the
university in marketing the device.

DOD Seeks Army of Cyborg Bugs
Computerworld (03/15/06) Songini, Marc L.
DARPA's Hybrid Insect Micro-Electrical-Mechanical Systems (HI-MEMS)
program is calling for proposals to develop insect cyborg-scouts that can
be controlled remotely. The insects would carry sensors and a wireless
transmitter enabling them to relay information about conditions in
locations inaccessible to human soldiers. DARPA wants to develop an insect
capable of being directed to within five meters of a target at a 100-meter
range with an electric remote control or a GPS application. DARPA has yet
to determine the technical specifications of the insect scouts, though it
has suggested that they could serve as "micro unmanned air vehicles" to
access areas too remote or dangerous for humans, such as enemy buildings or
caves. Previous attempts to use insects to gather intelligence have been
limited by unreliable performance, which the HI-MEMS project seeks to
correct with a dependable control interface. DARPA says the body of an
insect, as it passes through its metamorphic stages, would renew itself
around foreign objects, such as a gas sensor, a video camera, and a
microphone. "Inserting MEMS devices during such stages could enable
assembly-line like fabrication of hybrid insect-MEMS interfaces, providing
a considerable cost advantage," according to a DARPA report. DARPA is also
interested in swimming devices, provided that the insect can stay still
until it is directed to move by its handler. Powering the device and
controlling the locomotion are among the project's central challenges.

Optical-Wireless Convergence: New Network Architecture
Delivers Super-Broadband Wired and Wireless Service Simultaneously
Georgia Institute of Technology (03/16/06)
Georgia Tech researchers have developed a hybrid communication network
scheme that would enable wired and wireless transmissions of voice, data,
and video at speeds up to 100 times faster than existing networks. By
offering wired and wireless services over the same optical fiber, the
system would lower costs and improve service. "The same services would be
provided to customers who would either plug into the wired connection in
the wall or access the same information through a wireless system," said
Gee-Kung Chang, professor of electrical and computer engineering. Telecom
providers typically offer services that are either completely wired or
wireless, though the demand for greater bandwidth from wireless providers
to offer video, music, and Internet access is bringing the two sectors into
alignment. Chang's system would use the existing optical-fiber networks,
but up-convert their signals before entering a building to the
millimeter-wave spectrum while wireless and baseband signals would be
simultaneously converted to the millimeter-wave carrier. The passive
optical network infrastructure would split the signal into two parts and
carry it throughout the building. One of the signal components would be
detected and amplified by high-speed receivers while the other would be
accessed via a normal wall outlet. Each would provide data transmission
rates of 2.5 Gbps, a considerable improvement over existing Wi-Fi or WiMax
systems. Due to the high capacity of its optical fiber, the network could
support up to 32 distinct channels through wavelength division
multiplexing. Chang sees the technology reaching the market in five years
to seven years, though he acknowledges the need for new antennas and
component prices to drop.

Enigma Project Cracks Second Code
BBC News (03/15/06)
Thousands of online codebreakers continue to use distributed computing
power to decrypt three German codes that Allied forces were unable to crack
during World War II. Participants in the M4 Project, named after the M4
Enigma machine Germany used to encode its messages, have one remaining code
to crack. The remaining code is actually the first message the online
codebreakers attempted to crack, and all combinations available on German
army and three-ring Enigma machines have been tried. However, they did not
try combinations associated with the sophisticated four-ring Enigma used to
encode the messages. The online codebreakers recently cracked a message
that provided information about the aftermath of a battle with an Allied
vessel, and it followed the first breakthrough on Feb. 20, 2006, involving
a code that proved to be a confirmation of a message from the commander of
a German U-boat. War experts at Bletchley Park were unable to crack the
messages sent in 1942 because Germany used a new code book and a different
version of the Enigma machine. Amateur historian Ralph Erskine discovered
the codes and passed them on to a cryptography journal in 1995 as an
exercise for codebreakers.

Talking Computers Just Around the Corner
Sci-Tech Today (03/14/06) Millard, Elizabeth
The supplanting of the keyboard with speech-recognition technology as the
primary human-computer interface may be very close to realization thanks to
recent innovations. "Computers are getting smarter, and that's good for
speech recognition, but the better news is that society is getting
trained," says Serotek CEO Mike Calvo. The marketability of early
speech-recognition products was limited because the technology required
users to modify their speech patterns, but since then companies have
adopted a model in which they tailor products for specific sectors and
develop applications that fulfill particular requirements. Experts predict
the increased rollout of speech-recognition-equipped mobile devices, given
the business potential of the handset crowd, which already use the devices
for cell-phone calls or dictation and desire more features that will lessen
their reliance on small keyboards. Speech technology that can identify
emotions will attract considerable attention, while much of the industry is
pursuing interactive voice response systems that are smart enough to use
natural-language processing to handle customer calls and vastly improve
their accuracy and sensitivity. Spanlink Communications' Tim Kraskey says
such systems would be able to not only comprehend the meaning behind
customers' statements, but use that meaning to direct the caller or agent
to pertinent information. Mainstream adoption of speech-recognition
products faces daunting challenges, including hesitation among consumers,
scalability and throughput issues, the effort that goes into customization,
and the tendency for accents to trip up the technology.

Supercomputer Builds a Virus
Nature (03/14/06) Pearson, Helen
Researchers at the University of Illinois have used a supercomputer to
simulate an entire biological organism in greater detail than has ever been
achieved in the past. Klaus Schulten and his colleagues say their model of
the satellite tobacco mosaic virus could be the first step toward larger,
more complex simulations that reveal how viruses attack cells and spread
disease. Schulten and his team used the most recent version of the NAMD
program to harness the power of hundreds of processors working in parallel
within a supercomputer system. Housed at the National Center for
Supercomputing Applications in Urbana, the machine ran the program to
calculate the interactions between the virus' roughly 1 million atoms and a
surrounding drop of salt water at each femtosecond--a millionth of a
billionth of a second. The team modeled the virus for 50 billionths of a
second, which would have taken 35 years on a normal desktop. Previous
computer simulations of viruses were often limited to only a portion of the
organism, but the holistic model takes the guesswork out of the study. As
supercomputing power advances, researchers expect to model more complex
biological systems for longer periods of time, enabling them to observe
critical processes such as a protein shutting off a gene in a cell.

PCAST Panel Ready to Roll
Federal Computer Week (03/13/06) Vol. 20, No. 4, P. 55; Sternstein, Aliya
Following President Bush's dissolution of the President's IT Advisory
Committee (PITAC), the panel's functions were rolled into the President's
Council of Advisors on Science and Technology (PCAST), which will welcome
14 new members. PCAST will have a total of 38 members with the addition of
such science and technology experts as Dell founder Michael Dell,
Microsoft's Robert Herbold, Intel co-founder Gordon Moore, and Renaissance
Computing Institute director Dan Reed, the only PCAST member who belonged
on the now-defunct PITAC. The nearly nine-month delay in the election of
new PCAST council members was a point of concern for researchers worried
that the federal government's failure to support research beyond homeland
security or defense programs would have a detrimental effect on U.S. jobs
and national competitiveness. Bush's announcement in January of the
American Competitiveness Initiative, which seeks to spur research and
development in major scientific areas such as supercomputing, alternative
energy sources, and nanotechnology through R&D, education, and workforce
and immigration policies, helped assuage those concerns somewhat.
Following the expiration of PITAC, former PITAC members released a final
report recommending long-term investment in computational science research,
and an accelerated study on how federal spending can advance computational
science in academia, government, and industry. Reed explained that PCAST
needs to assess the general federal IT R&D budget in order for the United
States to move forward in the general sciences and to improve its
competitiveness.

Intel Plugs Into System Power
eWeek (03/13/06) Vol. 23, No. 11, P. 9; Spooner, John G.
More efficient power management is a priority for Intel, and company
officials think systems' average power consumption could be reduced by as
much as 40 percent through a series of efforts, according to their
statements at the Intel Developer Forum. Though officials did not foresee
any commercial products for several years, they were confident that these
initiatives could substantially lower electric bills. Intel is employing a
two-pronged strategy: One effort involves the release of a new generation
of power-efficient processors, while the other effort is the
Energy-Efficient Systems Architecture (EESA) project to modify the
computer's inner workings. EESA espouses finer power management
methodology in which systems function more efficiently with no noticeable
impact on performance to users or technology departments, and a such a
breakthrough could be reached through the creation of more powerful
manageability engines or purpose-built microcontrollers that perform
internal system tasks, according to Intel Systems Technology Lab director
Raj Yavatkar. Finer memory management might also be achieved one day by a
more sophisticated engine, notes Yavatkar. Furthermore, his lab is
exploring techniques to devise more efficient power supplies and re-tune
voltage regulation circuits, which could also reduce energy consumption.

Found in Translation
Military Information Technology (03/14/06) Vol. 10, No. 2,Gerber, Cheryl
The Defense Advanced Research Projects Agency's (DARPA) Global Autonomous
Language Exploitation (GALE) program seeks to develop, combine, and apply
technologies that will examine and translate vast amounts of speech and
text in multiple dialects, and implement them through a trio of processing
engines tasked with the transcription, translation, and distillation of
relevant data. The transcription engine will render audio as English text;
the translation engine will convert text from other languages into English,
providing annotations concerning the language of origin, topics, speech
elements, names, and other factors; and the distillation engine will look
for and blend information from numerous sources that relates to specific
queries, eliminating repetition. There is a need among many agencies for
more foreign language skills and searchable language-translation technology
that the GALE program is directly addressing. Of the three prime
contractor teams developing GALE technology, IBM Research is concentrating
on the construction of statistical machine translation between any pair of
a half-dozen parallel texts (English, Spanish, French, Arabic, Chinese, and
Russian) using data from United Nations proceedings. Another GALE
contractor, BBN Technologies, is tasked with speech recognition,
speech-to-text transcription, machine translation, and
transcription/translation integration. In addition, BBN and its
subcontractors are contracted to develop a semantic model for languages'
data structures, extract and distill pertinent translated language, and
combine the various technologies in an operational system. One
subcontractor, Language Computer, is using its Power Answer and Power Tools
products to provide answers to natural language queries that are more
precise and entail less distillation. Another area of concentration for
the GALE contractors and subcontractors is finding a solution to the
problem of document triage in foreign language, and IBM is exploring the
strengths and weaknesses of two strategies: Issuing a query in English and
issuing a query in the source language.
