Cloud-Based Automated Software Reliability Services Google Tech Talk July 22, 2010 ABSTRACT Presented by Professor George Candea people.epfl.ch This talk proposes cloud-based automated software reliability services (SRS), a step toward making testing and debugging of code as easy as using webmail. SRS is automatic, without human involvement from the service user's or provider's side; this is unlike today's "testing as a service" businesses, which employ humans to write tests. First, I will outline four of the SRS components we envision: a "home edition" on-demand testing service for consumers to verify the software they are about to install on their PC or mobile device; a "programmer's sidekick" enabling developers to thoroughly and promptly test their code with minimal upfront resource investment; a public "certification service," akin to Underwriters Labs, that independently assesses the reliability, safety, and security of software; and an "automated debugging" service that helps developers fix code based on bug reports from the field. Then I will present in detail execution synthesis, the technique that makes automated debugging (the latter SRS component) a reality. Given a program and a bug report, execution synthesis combines static analysis and symbolic execution to "synthesize" a thread schedule and various required program inputs that cause the reported bug to manifest. The synthesized execution can then be played back deterministically in a regular debugger, like gdb. We have found this determinism to be <b>...</b> From: GoogleTechTalks Views: 6 0 ratings Time: 01:16:08 More in Science & Technology

Remote Mentoring with "We Teach Science" Google Tech Talk August 25, 2010 ABSTRACT Presented by Aragon Burlingham and Dina Moskowitz. There is a crisis occurring in Science and Math education on both a state and national level. In 2009, only 30% of California students scored at the proficient range or higher on state Algebra tests. California is the 8th largest economy in the world, with Silicon Valley the nation's epicenter of science and technology, yet our middle school students rank 45th in math and almost last in science understanding in the nation. This talk, by the We Teach Science Foundation, will outline the foundation's plan to combat this serious problem--the Remote Tutoring and Mentoring Program (RTM). In one hour per week, professionals from the STEM fields are providing a gift of mentorship to public school students, without even leaving their desks. Come find out what it's all about! History of the Organization In 2008, Aragon Burlingham left the field of engineering to focus on his life-long passion of enhancing the math and science learning experiences of children. After a stint of volunteering in a Pacifica, CA public school, he recognized the students' need for personalized attention. He sought to develop a one-on-one mentorship program using STEM professionals as volunteers. Originally, the program was face-to-face; a more traditional mentoring program. However, with the time constraints placed upon professionals, he realized the best way to connect students and mentors was online. Thus, the <b>...</b> From: GoogleTechTalks Views: 522 9 ratings Time: 19:51 More in Science & Technology

Playing to Lose: AI and "Civilization" (Soren Johnson) Google Tech ...
Playing to Lose: AI and "Civilization" (Soren Johnson) Google Tech Talk August 26, 2010 ABSTRACT Presented by Soren Johnson. Artificial intelligence is crucial to any strategy game, providing a compelling opponent for solo play. While many of the challenges of AI development are technical, significant design challenges exist as well. Can the AI behave like a human? Should it? Should the game design be adjusted to accommodate the limitations of the AI? How do we make the AI fun? Should the AI cheat? If so, how much? Do we even want the AI to win? This session suggests some possible answers to these questions using the "Civilization" series as a case study. Ultimately, developers must choose between a "good" AI and a "fun" one, with an understanding of the trade-offs inherent when deciding between the two. Soren Johnson was the lead designer and AI programmer for Sid Meier's Civilization IV. After working at Firaxis Games for seven years, Soren joined EA Maxis in 2007 to work on Spore as a lead designer/programmer. He is currently building web-based games with EA2D, such as the moddable strategystation.com and other unannounced projects. He also writes a design column for Game Developer Magazine and is on the GDC Advisory Board. His thoughts on game design can be found at www.designer-notes.com.

The War on Drugs Has Failed A Google Tech Talk ...
The War on Drugs Has Failed A Google Tech Talk August 17, 2010 ABSTRACT Presented by Stanford "Neill" Franklin, Police (Ret.) Executive Director, LEAP "It pains me to know that there is a solution for preventing tragedy and nothing is being done because of ignorance, stubbornness, unsubstantiated fear and greed." Hear Neill Franklin, Executive Director of LEAP (Law Enforcement Against Prohibition), speak on the problems and costs of the war on drugs, and the reasons society would be better off if it were ended. Founded on March 16, 2002, LEAP is made up of current and former members of the law enforcement and criminal justice communities who are speaking out about the failures of our existing drug policies. Those policies have failed, and continue to fail, to effectively address the problems of drug abuse, especially the problems of juvenile drug use, the problems of addiction, and the problems of crime caused by the existence of a criminal black market in drugs. Although those who speak publicly for LEAP are people from the law enforcement and criminal justice communities, a large number of our supporting members do not have such experience. You don't have to have law enforcement experience to join us. By continuing to fight the so-called "War on Drugs", the US government has worsened these problems of society instead of alleviating them. A system of regulation and control of these substances (by the government, replacing the current system of control by the black market) would be a less harmful <b>...</b> From: GoogleTechTalks Views: 1100 35 ratings Time: 01:10:21 More in Nonprofits & Activism

The Patent Game: Experiments in the Cathedral of Law Google ...
The Patent Game: Experiments in the Cathedral of Law Google Tech Talk August 16, 2010 ABSTRACT Presented by Andrew W. Torrance. The study of law has traditionally focused on close scrutiny of judicial decisions, statutes, regulations, and scholarly articles. We offer an alternative approach: experimental law. The Patent Game is an interactive web application, built using Ruby on Rails®, designed to be a simplified model of the patent system. Using The Patent Game, one may experimentally explore how patent systems work. Groups of human players can compete or collaborate with one another to come up with valuable new inventions, and then patent, make, sell, license, and buy these inventions. Patent owners may even litigate against patent infringers. By programmatically controlling various parameters of patent law, The Patent Game enables rigorous experiments into the impacts of those parameters on both choices human players make and various metrics of patent system performance. We have conducted several experimental studies so far, sometimes with surprising results. Data from our first study suggest that a commons offering no patent protection may generate more innovation, productivity, and wealth than a patent system. Our latest study, completed in July 2010, suggests that a patent system in which infringement results in monetary damages (a "liability rule") may generate more innovation, productivity, and wealth than a patent system in which infringement results in an injunction (a "property rule"). Although The Patent Game <b>...</b> From: GoogleTechTalks Views: 302 2 ratings Time: 01:20:48 More in Science & Technology

The Origin of the Universe and the Arrow of Time ...
The Origin of the Universe and the Arrow of Time Google Tech Talk August 13, 2010 ABSTRACT Presented by Sean Carroll. One of the most obvious facts about the universe is that the past is different from the future. We can remember yesterday, but not tomorrow; we can turn an egg into an omelet, but can't turn an omelet into an egg. That's the arrow of time, which is consistent throughout the observable universe. The arrow can be explained by assuming that the very early universe was extremely orderly, and disorder has been increasing ever since. But why did the universe start out so orderly? I will talk about the nature of time, the origin of entropy, and how what happened before the Big Bang may be responsible for the arrow of time we observe today. Speaker Info: Sean Carroll I'm a theoretical physicist at Caltech in sunny Pasadena, California. My research interests include theoretical aspects of cosmology, field theory, and gravitation. I want to learn about fundamental physics by studying the structure and evolution of the universe. These days I'm especially interested in inflation, the arrow of time, and what happened at or before the Big Bang. I've done a bunch of work on dark matter and dark energy, modified gravity, topological defects, extra dimensions, and violations of fundamental symmetries. I recently finished writing a popular-level book on cosmology and the arrow of time: From Eternity to Here: The Quest for the Ultimate Theory of Time, which I expect all of you to buy.

A Brief Prehistory of Voice over IP parts 1 & 2 Google Tech Talk August 10 & 11, 2010 ABSTRACT Presented by Danny Cohen and Stephen Casner. This talk explores the development of interactive packet voice beginning in 1974 with experiments over the ARPAnet in the NSC (Network Speech/Secure Communication) program sponsored by ARPA, initiated by Bob Kahn. One highlight will be the showing of a movie made in 1978 to demonstrate a multi-party teleconference over the packet network, including one participant interfaced from a telephone. The talk will be presented in two sessions (two days), with the movie shown at the start of the second session. Part one covers concepts and lessons from this project: * A 1971 realtime distributed flight simulation that sparked the idea * Understanding real-time vs non-real-time communication * Digital speech and the need to compress it (PCM, DPCM, CVSD, LPC/LPC10) * Network Voice Protocol (NVP) over the ARPAnet, type0/type3 packets * The birth of the Internet with TCP * Separating IP from TCP and adding UDP * Building NVP-II on top of IP * Adding packet video (DCT based compression) Part two emphasizes the development of the voice protocols: * Introducing and showing the teleconferencing movie from 1978 * Advances in equipment and function at the end of NSC in 1982 * Progress stalled, waiting to low-cost vocoding * Development of IP Multicast and the MBone * Evolution from NVP to RTP, and RTP design philosophy * Conferencing control protocols * More recent history of VoIP Speaker Info: Danny <b>...</b> From: GoogleTechTalks Views: 1003 7 ratings Time: 01:43:39 More in Science & Technology

Marijuana Legalization in California, Policy Perspectives Google Tech Talk July 15, 2010 ABSTRACT Visiting speaker, Beau Kilmer, Co-Director of the RAND Drug Policy Institute discusses the policy implications of marijuana legalization in California, nationally, and internationally. There has been a dramatic shift in drug policy in recent years. Ballot initiatives have been proposed at the state level, and municipalities are today grappling with how to regulate marijuana dispensaries and enforce existing drug laws. Kilmer brings his breadth of knowledge to bear on current drug policy trends. Beau Kilmer is Co-Director of the RAND Drug Policy Research Center. His primary fields of interest are illicit markets, community corrections, drug treatment, and the use of advanced technologies to help monitor drug and alcohol use among problem populations. Kilmer's current work includes projects to estimate the economic costs of drug use and evaluations of community-level effects of drug treatment. He is currently engaged by the European Commission to calculate the size of the global drug market and is also working on a project to improve available data for understanding drug-related crime in Europe. Before earning his doctorate, Kilmer worked with the San Francisco Drug Court as a Judicial Administration Fellow.

Angular: A Radically Different Way of Building AJAX Apps Google Tech Talk July 28, 2010 ABSTRACT Presented by Misko Hevery. Angular teaches your old browser new tricks. It is what HTML would have been like, if it was designed for building web-applications. Angular is radical because it eliminates boilerplate code with declarative rather than imperative syntax. Angular: * Allows you to create custom HTML elements and attributes that provide dynamic behavior * Declaratively describe web-applications behavior with little JavaScript. * Creates an environment that provides trivially reusable widgets, data-binding, "automatic MVC", server resources, and other primitives useful in building AJAX apps. * Builds apps that have orders of magnitude less JavaScript than equivalent apps written in classical way. * Eliminates waiting on compiling for UI changes.

God's Mechanics: The Religious Life of Techies Google Tech Talk August 3, 2010 ABSTRACT Presented by Brother Guy Consolmagno SJ How does religion work in a culture shaped by science and technology? How do scientists and engineers practice their religions? How in particular does a Jesuitbrother, and an MIT graduate with a PhD in planetary science, make sense of his Catholicism? God's Mechanics examines the personal religious life and theology of scientists and engineers — "Techies" — based on conversations with nearly a hundred techies in Silicon Valley (interviewed during the spring of 2007 during a six-week stay at Santa Clara University) and a first-person confession from a Jesuit scientist and astronomer at the Vatican Observatory. Brother Guy Consolmagno SJ was born in Detroit, Michigan. He earned undergraduate and masters' degrees from MIT, and a Ph. D. in Planetary Science from the University of Arizona, was a researcher at Harvard and MIT, served in the US Peace Corps (Kenya), and taught university physics at Lafayette College, Pennsylvania, before entering the Jesuits in 1989. At the Vatican Observatory since 1993, his research explores connections between meteorites, asteroids, and the evolution of small solar system bodies. He observes asteroids, moons, and Kuiper Belt comets with the Vatican's 1.8 meter telescope in Arizona, and curates the Vatican meteorite collection in Castel Gandolfo. Along with more than 100 scientific publications, he is the author of a number of popular books including Turn Left at <b>...</b> From: GoogleTechTalks Views: 1765 32 ratings Time: 55:17 More in Science & Technology
