The Paxos Algorithm
 
24:51
A Google TechTalk, 2/2/18, presented by Luis Quesada Torres. ABSTRACT: This Tech Talk presents the Paxos algorithm and discusses a fictional distributed storage system (i.e. simplified Megastore) based on Paxos. The Paxos algorithm is one of the most common consensus algorithms. Consensus algorithms are one of the mechanisms that allow satisfying consistency constraints in distributed systems with consistency constraints, whether they follow a leader-replica schema or a peer-to-peer schema. Leader-replica systems consist of a leader node that proposes, manages, accepts, and serializes changes, and replica nodes that propose changes to the current leader node. Given that a single entity is in charge of acception and serialization, leader-replica systems do not require consensus algorithms in order to agree on what the next state is. However, if the leader node becomes unreachable, the replica nodes need to agree on which one should become the next leader node, and they usually run consensus algorithms to reach that agreement. Peer-to-peer systems consist of nodes that can propose changes and participate in accepting changes. The nodes need to agree on what the next state is in order to establish consistency, and they usually run consensus algorithms to reach that agreement. SREs within and outside Google work with highly scalable (and therefore distributed) systems that have consistency constraints and involve consensus algorithms.

Emacs Org-mode - a system for note-taking and project planning
 
46:57
Google Tech Talks July 15, 2008 ABSTRACT Org-mode is a large Emacs sub-systems that has been integrated into Emacs with the version 22.1 release. From it original intend, Org-mode is a system for structured note-taking and project planning. It uses strictly plain text files, making it a truly portable, system-independent solution. The project-planning features are implemented using a fairly simple outlining paradigm, upon which meta-data concepts like due dates, priorities, TODO states and tags are overlayed in a non-intrusive way. Besides outlining the system and its basic concepts, I will give background information into the history of Org-mode and discuss the properties of such an evolved system compared to a top-down designed one. Finally, I will also briefly touch on some technical aspects that may be interesting for Emacs wizards and developers. Speaker: Carsten Dominik

Bay Area Vision Meeting: Unsupervised Feature Learning and Deep Learning
 
48:10
Bay Area Vision Meeting (more info below) Unsupervised Feature Learning and Deep Learning Presented by Andrew Ng March 7, 2011 ABSTRACT Despite machine learning's numerous successes, applying machine learning to a new problem usually means spending a long time hand-designing the input representation for that specific problem. This is true for applications in vision, audio, text/NLP, and other problems. To address this, researchers have recently developed "unsupervised feature learning" and "deep learning" algorithms that can automatically learn feature representations from unlabeled data, thus bypassing much of this time-consuming engineering. Building on such ideas as sparse coding and deep belief networks, these algorithms can exploit large amounts of unlabeled data (which is cheap and easy to obtain) to learn a good feature representation. These methods have also surpassed the previous state-of-the-art on a number of problems in vision, audio, and text. In this talk, I describe some of the key ideas behind unsupervised feature learning and deep learning, describe a few algorithms, and present case studies pertaining. The Bay Area Vision Meeting (BAVM) is an informal gathering (without a printed proceedings) of academic and industry researchers with interest in computer vision and related areas. The goal is to build community among vision researchers in the San Francisco Bay Area, however, visitors and travelers from afar are also encouraged to attend and present. New research, previews of work to be shown at upcoming vision conferences, reviews of not-well-publicized work, and descriptions of "work in progress" are all welcome.

Be Your Own Therapist
 
01:01:11
Google Tech Talks October 3, 2008 ABSTRACT We spend our lives being seduced by the outside world, believing without question that happiness and suffering come from "out there." In reality, Buddhist teachings explain that they come from the way we perceive and interpret things, not the things themselves. This deeply held misconception is at the root of our dissatisfaction, self-doubt, anger, depression, anxiety, and the rest. But our minds can change. By becoming deeply familiar with the workings of our own cognitive processes through introspection and learning to deconstruct them - truly, being our own therapists - we can loosen the grip of these neuroses and grow our marvelous potential for contentment, clarity, and courage, which are at the core of our being. Speaker: Venerable Robina Courtin A Tibetan Buddhist nun for 30 years, beloved teacher and power-house personality, Ven. Robina Courtin is Executive Director of Liberation Prison Project, based in San Francisco. (LiberationPrisonProject.org) A lifeline for people with nothing and no one, since 1996 Liberation Prison Project has supported the spiritual practice of over 15,000 prisoners, mainly in the US and Australia. These days, the project spends $50,000 every month, nearly half of it on salaries and benefits for a fulltime staff of ten (eight in the US and two in Australia, including three former prisoners), supported by a team of 150+ volunteers worldwide. Ven. Robina travels the world, teaching and raising funds, touching countless hearts and minds with her down-to-earth, no-nonsense packaging of the Buddha's teachings, often filled with tasty stories from her own real-life struggles, attachments and relationships. She is able to put across to her students in and out of prison that change is possible; everyone can learn to develop their qualities, to be joyful in the face of difficulties - even on death row. "Ven. Robina has taught me to look at everything that occurs in my life with a different view," writes one Australian prisoner. "She has given me dignity, courage, and honor."

Google Personal Growth Series: Mindsight: The New Science of
 
01:02:52
Google Tech Talks April 22, 2009 ABSTRACT This interactive talk will examine two major questions: What is the mind? and How can we create a healthy mind? We'll examine the interactions among the mind, the brain, and human relationships and explore ways to create a healthy mind, an integrated brain, and mindful, empathic relationships. Here is one surprising finding: the vast majority (about 95%) of mental health practitioners around the globe, and even many scientists and philosophers focusing on the mind, do not have a definition of what the mind is! In this talk, well offer a working definition of the mind and practical implications for how to perceive and strengthen the mind itself—a learnable skill called mindsight. Then well build on this perspective to explore ways that the mind, the brain, and our relationships are influenced by digital information flow and also how they can be moved toward healthy functioning.

Google Tech Talks Web Exponents presented by Doug Crockford February 27, 2009 blog post: http://google-code-updates.blogspot.com/2009/03/doug-crockford-javascript-good-parts.html JavaScript is a language with more than its share of bad parts. It went from non-existence to global adoption in an alarmingly short period of time. It never had an interval in the lab when it could be tried out and polished. JavaScript has some extraordinarily good parts. In JavaScript there is a beautiful, highly expressive language that is buried under a steaming pile of good intentions and blunders. The best nature of JavaScript was so effectively hidden that for many years the prevailing opinion of JavaScript was that it was an unsightly, incompetent abomination. This session will expose the goodness in JavaScript, an outstanding dynamic programming language. Within the language is an elegant subset that is vastly superior to the language as a whole, being more reliable, readable and maintainable. Speaker: Douglas Crockford Douglas Crockford is a product of our public education system. A registered voter, he owns his own car. He has developed office automation systems. He did research in games and music at Atari. He was Director of Technology at Lucasfilm. He was Director of New Media at Paramount. He was the founder and CEO of Electric Communities/Communities.com.

Cognitive Neuroscience of Mindfulness Meditation
 
48:54
Google Tech Talks February, 28 2008 ABSTRACT Mindfulness meditation, one type of meditation technique, has been shown to enhance emotional awareness and psychological flexibility as well as induce well-being and emotional balance. Scientists have also begun to examine how meditation may influence brain functions. This talk will examine the effect of mindfulness meditation practice on the brain systems in which psychological functions such as attention, emotional reactivity, emotion regulation, and self-view are instantiated. We will also discuss how different forms of meditation practices are being studied using neuroscientific technologies and are being integrated into clinical practice to address symptoms of anxiety, depression, and stress. Speaker: Philippe Goldin Philippe is a research scientist and heads the Clinically Applied Affective Neuroscience group in the Department of Psychology at Stanford University. He spent 6 years in India and Nepal studying various languages, Buddhist philosophy and debate at Namgyal Monastery and the Dialectic Monastic Institute, and serving as an interpreter for various Tibetan Buddhist lamas. He then returned to the U.S. to complete a Ph.D. in Clinical Psychology at Rutgers University. His NIH-funded clinical research focuses on (a) functional neuroimaging investigations of cognitive-affective mechanisms in adults with anxiety disorders, (b) comparing the effects of mindfulness meditation and cognitive-behavioral therapy on brain-behavior correlates of emotional reactivity and regulation, and (c) training children in family and elementary school settings in mindfulness skills to reduce anxiety and enhance compassion, self-esteem and quality of family interactions.

Sensor Fusion on Android Devices: A Revolution in Motion Processing
 
46:27
Google Tech Talk August 2, 2010 ABSTRACT Presented by David Sachs. Gyroscopes, accelerometers, and compasses are increasingly prevalent in mainstream consumer electronics. Applications of these sensors include user interface, augmented reality, gaming, image stabilization, and navigation. This talk will demonstrate how all three sensor types work separately and in conjunction on a modified Android handset running a modified sensor API, then explain how algorithms are used to enable a multitude of applications. Application developers who wish to make sense of rotational motion must master Euler angles, rotation matrices, and quaternions. Under the hood, sensor fusion algorithms must be used in order to create responsive, accurate, and low noise descriptions of motion. Reducing sensing errors involves compensating for temperature changes, magnetic disturbances, and sharp accelerations. Some of these algorithms must run at a very high rate and with very precise timing, which makes them difficult to implement within low-power real-time operating systems. Within Android specifically, this involves modifying the sensor manager, introducing new APIs, and partitioning motion processing tasks. David Sachs began developing motion processing systems as a graduate student at the MIT Media Lab. His research there led him to InvenSense, where he continues this work with MEMS inertial sensors used in products such as the Nintendo Wii Motion Plus. David's designs incorporate gyroscopes, accelerometers, and compasses in various combinations and contexts including handset user interfaces, image stabilizers, navigation systems, game controllers, novel Braille displays, and musical instruments.

GTAC 2013: Web Performance Testing with WebDriver
 
14:25
http://g.co/gtac2013 Slides: http://goo.gl/5QHVY Demo code: https://gist.github.com/klepikov/5457750 Michael Klepikov, Google In web performance testing, we know pretty well how to analyze a page load. We need to move beyond a page load though: modern apps are highly interactive, and operations tend not to reload the entire page, but rather update it. Different people, myself included, have integrated WebDriver into web performance test harnesses, which helps, but still keeps performance tests separate from the rest of the UI test suite. I propose to build performance testing features right into WebDriver itself, leveraging its recently added Logging API. This makes it possible to collect performance metrics while running regular functional tests, allowing for a much more seamless integration of performance tests into the overall development and test flow. It is also much less disruptive to the custom build/test toolchains that almost every large organization creates. I will demonstrate this with the new-generation ChromeDriver (WebDriver for the Chromium browser).

The Liquid Fluoride Thorium Reactor:  What Fusion Wanted To Be
 
55:17
Google Tech Talks November 18, 2008 ABSTRACT Electrical power is, and will increasingly become, the desired form of energy for its convenience, safety, flexibility and applicability. Even future transportation embraces electric cars, trains, and chemical fuel production (jet fuel, hydrogen, etc.) based upon an abundant electrical supply. Although existing energy sources can and should be expanded where practical, no one source has shown to be practical to rapidly fulfill the world's energy requirements effectively. Presently there is an existing source of energy ideally suited to electrical energy production that is not being exploited anywhere in the world today, although its existence and practicality has been know since the earliest days of nuclear science. Thorium is the third source of fission energy and the LFTR is the idealized mechanism to turn this resource into electrical energy. Enough safe, clean energy, globally sustainable for 1000's of years at US standards. This talk is aimed at explaining this thorium energy resource from fundamental physics to today's practical applications. The presentation is sufficient for the non-scientist to grasp the whole subject, but will be intriguing to even classically trained nuclear engineers. By providing the historical context in which the technology was discovered and later developed into a power reactor, the story of thorium's disappearance as an energy source is revealed. But times have changed, and today, thorium energy can be safely exploited in a completely new form of nuclear reactor. The LFTR is unique, having a hot liquid core thus eliminating fuel fabrication costs and the need for a large reactor. It cannot have a nuclear meltdown and is so safe that typical control rods are not required at all. This design topples all the conventional arguments against conventional energy sources in such areas as: * Waste Production * Safety * Proliferation * Capital Costs and Location * Environmental Impact * Social Acceptance * Flexibility * Grid Infrastructure * Efficiency Should America take this step toward a New Era in Nuclear Energy Production? Hear the case for "The Electricity Rock" and then decide. Speaker: Dr. Joe Bonometti Dr. Bonometti has extensive engineering experience in the government, within industry, and in academia over a 25-year career. Recently completing an assignment as the NASA Chair Professor at the Naval Post graduate School, he supported a ship design study that utilized advanced nuclear power derived from thorium. Working at NASA for ten years as a technology manager, lead systems engineer, nuclear specialist, and propulsion researcher, he lead several NASA tiger teams in evaluating the Nuclear System Initiatives fission demonstration vehicle and missions. He managed the Emerging Propulsion Technology Area for in-space systems, the Marshall Air Launch team, as well as a variety of other power and propulsion assignments and is now the Lead Systems Engineer for the Ares I-Y flight. After earning a Doctorate degree in Mechanical Engineering from University of Alabama in Huntsville, he spent several years as a Research Scientist & Senior Research Engineer at the UAH Propulsion Research Center where he served as a Principal Investigator and manager for the Solar Thermal Laboratory. He has worked as a Senior Mechanical Designer at Pratt & Whitney supporting aircraft engine manufacturing and at the Lawrence Livermore National Laboratory within the laser fusion program. A graduate from the United States Military Academy, at West Point, where he studied nuclear physics and engineering, Dr. Bonometti served as an officer in the United States Army Corps of Engineers; both in combat and district engineering management assignments. He is a Registered Professional Engineer in the State of Virginia, and has authored numerous aerospace technical publications, particularly propulsion and space systems technologies.

Eric Ladizinsky: Evolving Scalable Quantum Computers
 
01:12:00
Eric Ladizinsky visited the Quantum AI Lab at Google LA to give a talk "Evolving Scalable Quantum Computers." This talk took place on March 5, 2014. Abstract: EVOLVING QUANTUM COMPUTERS: "The nineteenth century was known as the machine age, the twentieth century will go down in history as the information age. I believe the twenty-first century will be the quantum age". Paul Davies Quantum computation represents a fundamental paradigm shift in information processing. By harnessing strange, counterintuitive quantum phenomenon, quantum computers promise computational capabilities far exceeding any conceivable classical computing systems for certain applications. These applications may include the core hard problems in machine learning and artificial intelligence, complex optimization, and simulation of molecular dynamics .. the solutions of which could provide huge benefits to humanity. Realizing this potential requires a concerted scientific and technological effort combining multiple disciplines and institutions ... and rapidly evolving quantum processor designs and algorithms as learning evolves. D-Wave Systems has built such a mini-Manhattan project like effort and in just a under a decade, created the first, special purpose, quantum computers in a scalable architecture that can begin to address real world problems. D-Wave's first generation quantum processors (now being explored in conjunction with Google/NASA as well as Lockheed and USC) are showing encouraging signs of being at a "tipping point" .. matching state of the art solvers for some benchmark problems (and sometimes exceeding them) ... portending the exciting possibility that in a few years D-Wave processors could exceed the capabilities of any existing classical computing systems for certain classes of important problems in the areas of machine learning and optimization. In this lecture, Eric Ladizinsky, Co-Founder and Chief Scientist at D-Wave will describe the basic ideas behind quantum computation , Dwave's unique approach, and the current status and future development of D-Wave's processors. Included will be answers to some frequently asked questions about the D-Wave processors, clarifying some common misconceptions about quantum mechanics, quantum computing, and D-Wave quantum computers. Speaker Info Eric Ladizinsky is a physicist, Co-founder, and Chief Scientist of D-Wave Systems. Prior to his involvement with D-Wave, Mr. Ladizinsky was a senior member of the technical staff at TRW's Superconducting Electronics Organization (SCEO) in which he contributed to building the world's most advanced Superconducting Integrated Circuit capability intended to enable superconducting supercomputers to extend Moore's Law beyond CMOS. In 2000, with the idea of creating a quantum computing mini -Manhattan-project like effort, he conceived, proposed, won and ran a multi-million dollar, multi-institutional DARPA program to develop a prototype quantum computer using (macroscopic quantum) superconducting circuits. Frustrated with the pace of that effort Mr. Ladizinsky, in 2004, teamed with D-Wave's original founder (Geordie Rose) to transform the then primarily IP based company to a technology development company modeled on his mini-Manhattan-project vision. He is also responsible for designing the superconducting (SC) IC process that underlies the D-Wave quantum processors ... and transferring that process to state of art semiconductor production facilities to create the most advanced SC IC process in the world.

Visualizing Data Using t-SNE
 
55:10
Google Tech Talk June 24, 2013 (more info below) Presented by Laurens van der Maaten, Delft University of Technology, The Netherlands ABSTRACT Visualization techniques are essential tools for every data scientist. Unfortunately, the majority of visualization techniques can only be used to inspect a limited number of variables of interest simultaneously. As a result, these techniques are not suitable for big data that is very high-dimensional. An effective way to visualize high-dimensional data is to represent each data object by a two-dimensional point in such a way that similar objects are represented by nearby points, and that dissimilar objects are represented by distant points. The resulting two-dimensional points can be visualized in a scatter plot. This leads to a map of the data that reveals the underlying structure of the objects, such as the presence of clusters. We present a new technique to embed high-dimensional objects in a two-dimensional map, called t-Distributed Stochastic Neighbor Embedding (t-SNE), that produces substantially better results than alternative techniques. We demonstrate the value of t-SNE in domains such as computer vision and bioinformatics. In addition, we show how to scale up t-SNE to big data sets with millions of objects, and we present an approach to visualize objects of which the similarities are non-metric (such as semantic similarities). This talk describes joint work with Geoffrey Hinton.

Clarifying the Tubulin bit/qubit - Defending the Penrose-Hameroff Orch OR Model (Quantum Biology)
 
45:54
Google Workshop on Quantum Biology Clarifying the tubulin bit/qubit - Defending the Penrose-Hameroff Orch OR Model of Quantum Computation in Microtubules Presented by Stuart Hameroff October 22, 2010 ABSTRACT The Penrose-Hameroff theory of orchestrated objective reduction (Orch OR) postulates quantum computation in microtubules inside brain neurons underlying consciousness. Specifically, Orch OR proposes that tubulin proteins comprising microtubule cylindrical lattices function as 'bits' -- switching between alternative states (e.g. of 1 or 0), as well as quantum bits or 'qubits' (existing transiently as quantum superposition of both 1 AND 0). Despite increasing evidence for functional quantum effects in warm biological systems, Orch OR has been recently criticized, e.g. in Phys Rev E by McKemmish et al (2009), who claim the nature and energetic requirements for switching of tubulin bits and qubits in microtubules make Orch OR biologically unfeasible and unsalvageable irrespective of any conceivable modification. Here we show that McKemmish et al misrepresent tubulin bit switching as proposed in Orch OR, and merely disprove their own misrepresentation. Specifically we address their allegations regarding regulation of tubulin switching by 1) van der Waals London forces, 2) GTP hydrolysis and 3) Fröhlich coherence, and show how they are wrong on all counts. We clarify certain aspects of tubulin with regard to potential bit/qubit function, and describe topological tubulin qubits specific to microtubule geometry with particular reference to helical ballistic conductance discovered by Bandyopadhyay. Orch OR remains viable and testable. About the speaker: Stuart Hameroff MD is Professor of Anesthesiology and Psychology, and Director of the Center for Consciousness Studies at the University of Arizona Medical Center in Tucson, Arizona. A clinical anesthesiologist, Hameroff's academic research for 35 years has focused on how the brain produces consciousness, and how anesthetic gases selectively erase it. In medical school in the early 1970s Hameroff became interested in microtubules and developed a theory of microtubules as self-organizing molecular automata supporting consciousness and other functions inside brain neurons. In 1987 he authored Ultimate Computing: Biomolecular Consciousness and Nanotechnology, a survey of microtubule capabilities and potentials. In the early 1990s Hameroff teamed with British physicist Sir Roger Penrose to develop the controversial Penrose-Hameroff "Orch OR" model of consciousness based on microtubule quantum computation, a theory bolstered by recent discoveries of warm quantum coherence in biology. Hameroff also organizes the conference series Toward a Science of Consciousness, has written and co-edited 4 other books and numerous research articles, and recently developed the 'conscious pilot', a theory supportive of Orch OR involving spatiotemporal envelopes of dendritic synchrony moving through the brain as a conscious agent. Hameroff's research website is http://www.quantumconsciousness.org.

GTAC 2013: AddressSanitizer, ThreadSanitizer and MemorySanitizer -- Dynamic Testing Tools for C++
 
29:14
http://g.co/gtac2013 Slides: http://goo.gl/FPVd8 Kostya Serebryany, Google AddressSanitizer (ASan) is a tool that finds buffer overflows (in stack, heap and globals) and use-after-free bugs in C/C++ programs. ThreadSanitizer (TSan) finds data races in C/C++ and Go programs. MemorySanitizer (MSan) is a work-in-progress tool that finds uses of uninitialized memory (C++). These tools are based on compiler instrumentation (LLVM and GCC), which makes them very fast (e.g. ASan incurs just 2x slowdown). We will share our experience in huge scale testing using these tools.

Playing to Lose: AI and "Civilization" (Soren Johnson)
 
01:00:29
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 http://www.designer-notes.com.

Save the Uranium-233, Explore Space, Save Lives
 
25:03
Google Tech Talk January 13, 2011 Presented by Kirk Sorensen. ABSTRACT Uranium-233 does not exist naturally, but about a ton of the stuff was transmuted from Thorium-232 at the Oak Ridge National Laboratory in the 1960's. Some people would have us blend this exceedingly rare element with natural uranium for disposal. However, Uranium-233 can be used in an advanced nuclear reactor with interesting properties. Uranium-233 is the cleanest burning fissile material. Employed as an initial fuel load for a Liquid Fluoride Thorium Reactor, this small supply of Uranium-233 can be the match to ignite a process that produces a huge supply of electricity along with small quantities of useful fission products. In particular, the LFTR produces small amounts of Plutonium-238, essential for NASA's deep space missions; Technetium-99m, exceedingly valuable for medical imaging; and other specialized isotopes used in cancer treatments. Nuclear power reactors can be engineered to produce many valuable materials through transmutation belying the term "nuclear waste". Kirk Sorensen is chief nuclear technologist at Teledyne Brown Engineering in Huntsville, Alabama. He has been researching the nuclear fuel cycle for many years in connection with a strong interest in thorium as a planetary energy source. He is also a PhD student in nuclear engineering at the University of Tennessee in Knoxville under Dr. Laurence Miller. He runs a blog called "energyfromthorium.com" and is active in the Thorium Energy Alliance (TEA) and the International Thorium Energy Organization (IThEO) and is also a member of the American Nuclear Society (ANS).

Meaningful Play: Getting Gamification Right
 
49:57
Google Tech Talk January 24, 2011 Presented by Sebastian Deterding ABSTRACT Foursquare, GetGlue, Nike+, Badgeville: From reading news to fulfilling your hearts' desires, more and more "gameified" applications and "gamification" vendors doll out points and badges to users, promising anything from increased user engagement and retention to plain mind control. While some hold that adding such game elements to non-game applications opens a new decade of design, others criticize current implementations as shallow "pointsification" and overselling of a new digital snake oil. What lessons do games really offer for user experience design? Which criticisms are valid? And what can designers interested in "gameifying" an application do to steer clear of the worst pitfalls? In this talk, researcher and designer Sebastian Deterding provides an overview of the current gamification movement, its most troubling blind spots, the motivational powers of games, and how to design for a playful experience that is truly meaningful to its users. Sebastian Deterding - Sebastian Deterding is a user experience designer and game researcher at the University of Hamburg, Germany, where he currently pursues a PhD on the motivational psychology of gameified applications. He speaks and publishes internationally on gamification, social games, and the social contexts of video games at events such as the Gamification Summit, Gamescom, reboot, Playful, or DiGRA. His work has been covered by The Guardian, the LA Times, The New Scientist, EDGE Magazine, and Fast Company's Co.Design. He co-hosts the Gamification Workshop at this year's CHI conference in Vancouver.

The Poeticon: languages of sensorimotor representations and
 
01:02:44
Google Tech Talks May, 21 2008 ABSTRACT Reproducing an act with sensorimotor means and using fine natural language for communicating the intentionality behind the act is what Aristotle called "Poetics". POETICON explores the "poetics of everyday life", i.e. the synthesis of sensorimotor representations and natural language in everyday human interaction. This is related to an old problem in Artificial Intelligence on how meaning emerges, which is approached here in a new way. POETICON follows an empirical approach for discovering the "languages" of sensorimotor representations and the correspondences with natural language; guided by experiments in psychology and neuroscience, it employs cutting-edge equipment and established cognitive protocols for collecting face and body movement measurements, visual object information and associated linguistic descriptions from interacting human subjects, with a two-fold objective: a) The creation of the PRAXICON, an extensible computational resource which associates symbolic representations (words/concepts) with corresponding sensorimotor representations and that is enriched with information on patterns among these representations for forming conceptual structures. b) The exploration of the association of symbolic and sensorimotor representations through cognitive and neurophysiological experiments and experimentation with a humanoid as driving forces and implementation tools for the development of the PRAXICON, respectively. POETICON views a cognitive system as a set of different languages (the spoken, the motor, the vision language and so on) and provides a set of tools for parsing, generating and translating among them. Through inter-disciplinary research, it contributes to the exploration of what integration in human cognition is and how it can be reproduced by intelligent agents. This is an ambitious first step for revealing and conquering the "poetics of everyday life". * Research funded by the European Union, under the Cognitive Systems Program.

Is Nuclear Waste Really Waste?
 
40:40
Google Tech Talk December 6, 2010 Presented by Kirk Sorensen ABSTRACT An economic analysis of what is in spent nuclear fuel. As a nuclear reactor fissions heavy metal U235 and Pu239, the atoms are split into two randomly sized pieces. Many of these fission products are unstable and rapidly decay into other products. After nuclear reactor fuel has cooled in a pool of water for a few years, and then sat in dry cask storage for another 10--30 years, what is it made of? Is it dangerous waste that needs to be isolated from humanity for 100,000 years or is it precious material waiting to be partitioned and sold? The answer may surprise you. Speaker Info: Kirk Sorensen is chief nuclear technologist at Teledyne Brown Engineering in Huntsville, Alabama.

GET LAMP: The Text Adventure Documentary
 
02:01:18
Google Tech Talk (more below) March 7, 2011 Presented by Jason Scott. ABSTRACT Jason Scott will talk about making the documentary and we'll be screening some portion of the film. http://www.getlamp.com/ In the early years of the microcomputer, a special kind of game was being played. With limited sound, simple graphics, and tiny amounts of computing power, the first games on home computers would hardly raise an eyebrow in the modern era of photorealism and surround sound. In a world of Quake, Half-Life and Halo, it is expected that a successful game must be loud, fast, and full of blazing life-like action. But in the early 1980s, an entire industry rose over the telling of tales, the solving of intricate puzzles and the art of writing. Like living books, these games described fantastic worlds to their readers, and then invited them to live within them. They were called "computer adventure games", and they used the most powerful graphics processor in the world: the human mind. Rising from side projects at universities and engineering companies, adventure games would describe a place, and then ask what to do next. They presented puzzles, tricks and traps to be overcome. They were filled with suspense, humor and sadness. And they offered a unique type of joy as players discovered how to negotiate the obstacles and think their way to victory. These players have carried their memories of these text adventures to the modern day, and a whole new generation of authors have taken up the torch to present a new set of places to explore. Get Lamp is a documentary that will tell the story of the creation of these incredible games, in the words of the people who made them. Speaker Info: Jason Scott ( http://www.getlamp.com/director.html ) Jason Scott is a digital historian and archivist who specializes in early microcomputer history and dial-up bulletin board systems. He is the webmaster of textfiles.com, a collection of BBS-era textfiles that has been open to the public since 1998. In 2001, he began filming a documentary about BBSes called "BBS: The Documentary", an 8-episode mini-series about BBSes spanning 25 years and totalling five and a half hours in length. This documentary series was released on 3 DVDs in early 2005. He has been playing text adventures since he was 10, and to this day does not understand why the rod scares the bird.

Turing's Cathedral
 
01:08:08
Google Tech Talks April, 9 2008 ABSTRACT New Light on the Dawn of Digital Computing, 1945-1958 The digital universe consists of two kinds of bits: differences in space and differences in time. Digital computers translate between these two forms of information--structure and sequence--according to definite rules. Sixty-three years ago, at the Institute for Advanced Study in Princeton, NJ, John von Neumann and a small group of nonconformists launched a project to do this at electronic speed. The resulting architecture and coding has descended directly to almost all computers now in use. Von Neumann succeeded in jump-starting the computer revolution by bringing engineers into the den of the mathematicians, rather than by bringing mathematicians into a den of engineers. The stored-program computer, as conceived by Alan Turing and delivered by John von Neumann, broke the distinction between numbers that *mean* things and numbers that *do* things. Our universe would never be the same. With a mere 5 kilobytes of random access memory, von Neumann and colleagues tackled previously intractable problems ranging from thermonuclear explosions, stellar evolution, and long-range weather forecasting to cellular automata, genetic coding, and the origins of life. Programs were small enough to be completely debugged, but hardware could not be counted on to perform consistently from one kilocycle to the next. This situation is now reversed.

Google Tech Talks May, 12 2008 ABSTRACT Google will be hosting Dong Hyuk Shin, a 26-year-old North Korean defector born and raised in a concentration camp. Shin was born on Nov. 19, 1982 and called the camp home until 2005. While at the camp, he endured daily beatings, torture, starvation-level rations, saw forced abortions and even witnessed the public execution of his mother and brother in 1996. Shin described his life of total isolation from the world: "In South Korea, although there is disappointment and sadness, there is also so much joy, happiness and comfort. In Kaechon, I did not even know such emotions existed. The only emotion I ever knew was fear: fear of beatings, fear of starvation, fear of torture and fear of death." LiNK's Executive Director Adrian Hong will brief the audience on the broader issue of human rights in North Korea, as well as the current refugee situation and what can be done to help. Liberty in North Korea, or LiNK, is an international non-governmental organization devoted to human rights in North Korea and the protection of North Korean refugees. This talk will be taped. Speaker: Adrian Hong Adrian Hong: Adrian Hong currently serves as Executive Director of Liberty in North Korea, or LiNK, an international NGO devoted to human rights in North Korea, and the protection of North Korean refugees all over the world. In December of 2006, Mr. Hong was arrested along with 2 LiNK field workers and 6 North Korean refugees in the People's Republic of China and imprisoned before being released and deported Speaker: Dong-hyuk SHIN Dong-hyuk SHIN: Mr. Shin was born and raised in Political Prison Camp No. 14 until his escape in 2005. Based in South Korea, he has testified before Britain's House of Lords, and published a book in 2007 entitled "I Was a Political Prisoner at Birth in North Korea" published by the DataBase Center for North Korean Human Rights.

Google Tech Talk February 12, 2013 (more info below) Presented by Jeff Hawkins. ABSTRACT The neocortex works on principles that are fundamentally different than traditional computers. In this talk I will describe recent advances in understanding the neocortex and how we are applying them to model millions of high velocity data streams. The talk will start with a description of sparse distributed representations, which are the fundamental units of information in brains. I will then discuss how these representations are learned and how the brain processes them to build predictive models from sensory data. Numenta has built a product called Grok that emulates these capabilities of the neocortex. Grok is being used to understand high velocity machine generated data in many different domains. I will give a brief introduction to Grok and speculate on the future of machine intelligence.

(41:35) Wrap up (43:40) Questions and answers (45:30) ABSTRACT This talk describes our unique approach to constructing large, atomically precise molecules (called "Molecular Lego" or "spiroligomers") that could act as new therapeutics, new catalysts (molecules that make new chemical reactions happen faster) and ultimately to construct atomically precise molecular devices. Then I describe Clasp and CANDO, a new implementation of the powerful language Common Lisp. Clasp is a Common Lisp compiler that uses LLVM to generate fast machine code and it interoperates with C++. CANDO is a molecular design tool that uses Clasp as its programming language. Together I believe that these are the hardware (molecules) and the software (the CANDO/Clasp compiler) that will enable the development of sophisticated molecular nanotechnology. Clasp is available at: https://github.com/drmeister/clasp For more info see: https://chem.cst.temple.edu/directory/faculty/schafmeister/ More about Clasp Clasp is an implementation of Common Lisp that interoperates with C++ and uses LLVM as its backend. It is available at https://github.com/drmeister/clasp. The goal of Clasp is to become a performant Common Lisp that can use C++ libraries and interoperate with LLVM-based tools and languages. The first sophisticated C++ library with which Clasp interoperates is the Clang C/C++ compiler front end. Using the Clang library, Common Lisp programs can be written that parse and carry out static analysis and automatic refactoring of C/C++ code. This facility is used to automatically analyze the Clasp C++ source code and construct an interface to the Memory Pool System compacting garbage collector. The primary purpose of Clasp is to act as a performant language for scientific computing that will be used to design sophisticated new molecular devices, catalysts and therapeutic molecules based on our "Molecular Lego" technology. Clasp is a general programming language that will support many other applications. About the Speaker: Christian Schafmeister visited Google’s Cambridge, MA office to deliver the talk "Clasp: Common Lisp using LLVM and C++ for Molecular Metaprogramming”. Christian is Associate Professor of Chemistry at Temple University. Research projects within his group will use the tools of synthetic chemistry, molecular biology, and X-ray crystallography to develop a universal molecular scaffold that would allow the systematic design, construction, and investigation of macromolecules that display chemical functionality in three-dimensional space. A scaffold like this will allow the design and synthesis of new catalysts, molecular sensors, and ultimately molecular machines. His group will use synthetic chemistry to synthesize molecular building blocks that they will couple to each other through pairs of bonds to construct rigid macromolecules with diverse and programmable shapes. His group has developed computer software that allows the computer-aided design of these molecules to carry out specific functions.
