Google Tech Talks
November 8, 2006
ABSTRACT
The World Energy Council has estimated the
'useful' global ocean wave energy resource as 2TW
(17,500TWh/year). From this it has been estimated
(Thorpe 1999) that the practical economic
contribution from wave energy converters could be
2,000TWh/year (similar to current installed
nuclear or hydroelectric generation capacity).
Such generating capacity could result in up to 2
billion tonnes of CO2 emissions being displaced
from fossil fuel generation per year - similar to
current emissions from electricity generation in
the US.
Formed in 1998, based in Edinburgh, Scotland,
Ocean Power Delivery Ltd has developed the
'Pelamis' wave energy converter...

| An Overview of High Performance Computing and Challenges for the Future |
 |
Google Tech Talks
January, 25 2008
ABSTRACT
In this talk we examine how high performance
computing has changed
over the last 10-year and look toward the future
in terms of trends.
These changes have had and will continue to have a
major impact on our
software. A new generation of software libraries
and algorithms are
needed for the effective and reliable use of (wide
area) dynamic,
distributed and parallel environments. Some of the
software and
algorithm challenges have already been
encountered, such as management
of communication and memory hierarchies through a
combination of
compile--time and run--time techniques, but the
increased scale of
computation, depth of memory hierarchies, range of
latencies, and
increased run--time environment variability will
make these problems
much harder.
We will focus on the redesign of software to fit
multicore architectures.

| Wuala - a distributed file system |
 |
Google Tech Talks
October, 30 2007
ABSTRACT
After three years of research and development on a
distributed storage system, we are ready to unveil
the result: Wuala. Wuala is a new way of storing,
sharing, and publishing files on the internet.
Unlike traditional online storage systems, Wuala
is decentralized and can harness idle resources of
participating computers to build a large, secure,
and reliable online storage. This enables its
users to trade parts of their local storage for
online storage and it allows us to provide a
better service for free. In the talk, I will
explain what Wuala is and how it works, and I will
also show a demo. All attendees will also get an
invitation code to join the early alpha version.
Speaker: Dominik Grolimund
I am 26 years old and have studied computer
science at ETH Zurich. In 1998, I founded my
software company Caleido, and developed the
Caleido Address-Book, a professional contact
management software, of which over 35'000 licenses
have been sold so far in Switzerland, Germany and
Austria.
In 2003, I did an exchange semester at the TU
Delft, the Netherlands, as part of the Unitech
exchange program, focusing on business and
management. In 2004, a six-month internship
followed with Siemens Corporate Research in
Princeton, New Jersey in the US, where I worked in
the 'Intelligent Vision & Reasoning' department,

ABSTRACT
Vannevar Bush's 1945 article, "As We May Think,"
has been much celebrated as a central inspiration
for the development of hypertext and the World
Wide Web. Less attention, however, has been paid
to Bush's motivation for imagining a new
generation of information technologies; it was his
hope that more powerful tools, by automating the
routine aspects of information processing, would
leave researchers and other professionals more
time for creative thought. But now, more than
sixty years later, it seems clear that the
opposite has happened, that the use of the new
technologies has contributed to an accelerated
mode of working and living that leaves us less to
think, not more. In this talk I will explore how
this state of affairs has come about and what we
can do about it.
Speaker: David M. Levy
David Levy earned a Ph.D. in Computer Science at
Stanford University in 1979 and a Diploma in
Calligraphy and Bookbinding from the Roehampton
Institute (London) in 1983. For more than fifteen
years he was a researcher at the Xerox Palo Alto
Research Center (PARC), where his work, described
in "Scrolling Forward: Making Sense of Documents
in the Digital Age" (Arcade, 2001), centered on
exploring the transition from paper and print to
digital. During the year 2005-2006, he was the
holder of the Papamarkou Chair in Education and
Technology at the Library of Congress. A professor
at the UW Information School since 2000-2001, he
has been investigating how to restore
contemplative balance to a world marked by
information overload, fragmented attention,
extreme busyness, and the acceleration of everyday
life.

| Social Recommendations |
 |
Google Tech Talks
April, 10 2008
ABSTRACT
Social Recommendations will change both the lens
through which we see the world as well as the
manner in which we experience it. Everything from
the media that we consume to the events we attend
will be influenced by hyper-relevant results
delivered through hierarchical social
relationships. This talk demonstrates current
efforts to integrate social relationships into
recommended user experience including SoMR, the
Social Media Recommendation API.
Speaker: Dan Carroll
Dan is the Director of the SoMR (Social Media
Recommendation) project and the CEO of imp, the
Intelligent Media Platform. Dan has worked in
magazine and book publishing, labor organizing,
and at a public policy think tank. He holds a
patent in digital media distribution and writes
the blog www.mediapatron.com. Dan lives in
Mountain View, California and serves on the boards
of Echolocations and InRadio.

| Results of the Phoenix Mission to Mars and Analog sites on Earth |
 |
Google Tech Talks
October 6, 2008
ABSTRACT
Phoenix landed at 68N in the ice-rich ground on
Mars and investigated the chemistry and geology of
a polar site on Mars for the first time. The site
is particularly interesting for astrobiology
because 5 Myr ago the tilt of Mars' axis was 45
and the amount of sunlight reaching the Phoenix
site at summer solstice is 2x the present value -
Earth like levels. Understanding the microbial
activity in high elevation dry permafrost in
Antarctica provides a basis for considering
habitability conditions on Mars during these
periods of higher obliquity.
Speaker: Chris McKay, NASA Ames Research Center
Dr. Christopher P. McKay, Planetary Scientist with
the Space Science Division of NASA Ames. Chris
received his Ph.D. in AstroGeophysics from the
University of Colorado in 1982 and has been a
research scientist with the NASA Ames Research
Center since that time. His current research
focuses on the evolution of the solar system and
the origin of life. He is also actively involved
in planning for future Mars missions including
human settlements. Chris has been involved with
polar research since 1980, traveling to the
Antarctic dry valleys and more recently to the
Siberian and Canadian Arctic to conduct research
in these Mars-like environments. Dr. McKay is a
recepient of the prestigious Kuiper Award from the
Division of Planetary Sciences of the American
Astronomical Society for his contributions.

| A Possible Future of Software Development |
 |
Google Tech Talks
July, 25 2007
ABSTRACT
This talk begins with an overview of software
development at Adobe and a look at industry trends
towards systems built around object oriented
frameworks; why they "work", and why they
ultimately fail to deliver quality, scalable,
software. We'll look at a possible alternative to
this future, combining generic programming with
declarative programming to build high quality,
scalable systems.
Speaker: Sean Parent
Sean Parent is a principal scientist at Adobe
Systems and engineering manager of the Adobe
Software Technology Lab. One of his team's current
projects is the Adobe Source Libraries
