The Paxos Algorithm
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
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

Be Your Own Therapist
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."

JavaScript: The Good Parts
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.

Google Personal Growth Series: Mindsight: The New Science of
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.

Cognitive Neuroscience of Mindfulness Meditation
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.

Clarifying the Tubulin bit/qubit - Defending the Penrose-Hameroff Orch OR Model (Quantum Biology)
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.

The Liquid Fluoride Thorium Reactor:  What Fusion Wanted To Be
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. His technical expertise includes nuclear engineering, specialized mechanical & materials research, space plasmas & propulsion, thermodynamics, heat transfer, and space systems engineering.

Sensor Fusion on Android Devices: A Revolution in Motion Processing
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.

Seattle Conference on Scalability 2008: Chapel
Google Tech Talks June 14, 2008 ABSTRACT Chapel: Productive Parallel Programming at Scale Chapel is a new programming language being developed by Cray Inc. as part of the DARPA-led High Productivity Computing Systems Program (HPCS). Chapel strives to increase parallel programmability for supercomputer users by raising the level of abstraction compared to current parallel programming models. Language concepts that support this goal include abstractions for globally distributed data aggregates and anonymized task-based parallelism. Since locality is crucial when computing at large scales, Chapel also supports language concepts for reasoning about architectural locality on the target machine, including control over data placement and affinity between tasks and data. In contrast to previous higher-level parallel languages, Chapel is designed to be a "multi-resolution language", in which users can start by writing very abstract code and then incrementally add more detail until they are as close to the machine as that portion of their code requires. Although Chapel was not specifically designed for datacenter-oriented applications, many of its concepts should also be quite suitable for this domain given the importance of distributed data, concurrency, and affinity. In this talk, I will provide an overview of Chapel, explain how it was designed to help the HPC community, and describe its status. I will also attempt to make ties between its concepts and how they might be useful in a datacenter-based programming environment. Speaker: Bradford Chamberlain Bradford Chamberlain is a Principal Engineer at Cray Inc., where he works on parallel programming models, focusing primarily on the design and implementation of the Chapel parallel language in his role as technical lead for that project. Before starting at Cray in 2002, he spent a year at a start-up working at the opposite end of the hardware spectrum to design a parallel language (SilverC) for reconfigurable embedded hardware. Brad received his Ph.D. in Computer Science & Engineering from the University of Washington in 2001 where his work focused on the design and implementation of the ZPL parallel array language, particularly on implementing and generalizing its region concept -- --a first-class index set representation for programming with distributed arrays. While at UW, he also dabbled in algorithms for accelerating the rendering of complex 3D scenes. Brad remains associated with the University of Washington as an affiliate faculty member and most recently co-led a seminar there that focused on the design of Chapel. He received his Bachelor's degree in Computer Science from Stanford University with honors in 1992. Slides for this talk are available at http://groups.google.com/group/seattle-scalability-conference

Tools for Continuous Integration at Google Scale
Pre Google Test Automation Conference 2010 October 27th, 2010 Tools for Continuous Integration at Google Scale Presented by Nathan York. Abstract: Software engineers rarely invoke compilers and lower-level tools directly. Instead they interact with a build system which analyzes dependency information and then orchestrates the overall build process. Yet build systems are often overlooked by industry and academia. This presents a challenge for large organizations as their code base grows and engineering processes struggle to keep up. This talk covers the key insights and technical design elements that enable us to scale the word's largest continuously integrated code base to thousands of engineers worldwide. Speaker Bio: Nathan refers to himself as "a tools guy". He worked on IDEs and developer tools at Borland before joining Google 6 years ago. During this time he has been involved in transforming Google's tools and development process to scale with Google's rapid growth. He strongly believes that great engineering tools and process are one of the key elements required for successful software engineering.

Visualizing Data Using t-SNE
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.

How To Design A Good API and Why it Matters
Google Tech Talks January 24, 2007 ABSTRACT Every day around the world, software developers spend much of their time working with a variety of Application Programming Interfaces (APIs). Some are integral to the core platform, some provide access to widely distributed frameworks, and some are written in-house for use by a few developers. Nearly all programmers occasionally function as API designers, whether they know it or not. A well-designed API can be a great asset to the organization that wrote it and to all who use it. Good APIs increase the pleasure and productivity of the developers who use them, the quality of the software they produce, and ultimately, the corporate bottom line....

Worlds Upon Worlds: An Illustrated Talk by Toby Lester
Google Tech Talk August 23, 2010 ABSTRACT Toby Lester -- a longtime editor and writer for The Atlantic, and the author of The Fourth Part of the World (2009) -- will be here to talk about what may well be the greatest map ever made: the Waldseemüller world map of 1507. A giant wall map recently purchased by the Library of Congress for the astonishing sum of $10 million, the map's main claim to fame is that it gave America its name. But the map also represents a number of other important firsts in the history of cartography, and in the larger history of ideas. It was the first map to show the New World surrounded by water, and thus to suggest the existence of the Pacific Ocean; it was one of the very first maps to lay out a picture of the world in a full 360 degrees of longitude; and it was the first map to present the contours of the world's continents and oceans largely as we know them today. It was, in many ways, the mother of all modern world maps -- and yet, mysteriously, it was made years before Europeans first saw the Pacific or circumnavigated the globe. With the help of a weird and wonderful variety of early maps and diagrams, Lester will show how the Waldseemüller map for the first time brought together elements of many different ancient and medieval cartographic traditions and used them to create a map not only of space but also time -- a map that Chris Anderson, the editor of Wired, after reading about it in The Fourth Part of the World, described as "a sixteenth-century Google Earth."

Is Nuclear Waste Really Waste?
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. 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)

Protecting Freedom In The Patent System: The Public Patent Foundation's Missi...
Google Tech Talks August 6, 2008 ABSTRACT Many patents granted by the U.S. Patent and Trademark Office ("PTO") are undeserved. They are granted for several reasons, including that the PTO is not aware of significant prior art (knowledge already in the public domain), that the PTO's employees are not given sufficient time and resources to do an effective screening of patent applications and that the rules regarding how patents are granted are skewed through perverse patent policy to favor the granting of patents. Undeserved patents injure the public because they can be used by private actors to preclude activity that would otherwise be permissible, if not desirable. This causes prices for goods to be artificially high, the advancement of science to be thwarted, and civil liberties to be inappropriately restrained. The Public Patent Foundation ("PUBPAT") is a not-for-profit legal services organization whose mission is to represent the public interest against the harms caused by errors in the patent system, and particularly the harms caused by undeserved patents and unsound patent policy. PUBPAT provides the general public and specific persons or entities otherwise deprived of access to the system governing patents with representation, advocacy and education. In this Google Tech Talk, PUBPAT's Founder and Executive Director, Mr. Daniel B. Ravicher, will discuss PUBPAT's mission in greater detail and describe the specific activities PUBPAT undertakes to accomplish that mission. Speaker: Daniel B. Ravicher Daniel B. Ravicher is Executive Director of the Public Patent Foundation ("PUBPAT") and a Lecturer in Law and Associate Director of the Intellectual Property Law Program at Benjamin N. Cardozo School of Law. Prior to founding PUBPAT, Mr. Ravicher was associated with the patent law practice groups of Skadden, Arps, Slate, Meagher & Flom LLP, Brobeck, Phleger & Harrison, LLP, and Patterson, Belknap, Webb & Tyler, LLP, all in New York, and served the Honorable Randall R. Rader, Circuit Judge for the U.S. Court of Appeals for the Federal Circuit in Washington, D.C. Mr. Ravicher is a registered patent attorney and he writes and speaks frequently on patent law, including testifying before the U.S. Congress on the topic of patent reform. As a result of his accomplishments and professional reputation, IP Law & Business magazine included Mr. Ravicher on its 'Top 50 Under 45' list for 2008. Mr. Ravicher received his law degree from the University of Virginia School of Law, where he was the Franklin O'Blechman Scholar of his class, a Mortimer Caplin Public Service award recipient and an Editor of the Virginia Journal of Law and Technology, and his bachelors degree in materials science magna cum laude with University Honors from the University of South Florida.

Design Tech Talk Series Presents: OO Design for Testability
Google Tech Talk October 6, 2009 ABSTRACT Presented by Miško Hevery. We design our code for performance, maintenance, simplicity, extensibility and other goals, but most of us do not think about testability as a design goal, yet verifying the correctness of our code is of great importance. What does it mean to have testable code, and what kind of trade offs does one have to think about when designing for testability. Turns out that testable code is well designed code, and it has many of the characteristics we search for such as low cohesion, separation of concerns, proper encapsulation and many others.

GTAC 2013: Appium: Automation for Mobile Apps
http://g.co/gtac2013 Slides: http://goo.gl/IuvKF Jonathan Lipps, Sauce Labs Appium is is a Node.js server that automates native and hybrid mobile applications (both iOS and Android). Appium's philosophy dictates that apps should not be modified in order to be automated, and that you should be able to write your test code in any language or framework. The result is a Selenium WebDriver server that speaks mobile like a native. Appium runs on real devices and emulators and is completely open source, making it a wonderfully friendly way to get started with mobile test automation. In this talk I will outline the principles that inform Appium's design, talk about Appium in the space of other mobile automation frameworks, and introduce the architecture that makes the magic happen. Finally, I'll dig into the code for a simple test of a brand-new mobile app, and demonstrate Appium running this test on iPhone and Android.

Meaningful Play: Getting Gamification Right
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.

GET LAMP: The Text Adventure Documentary
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.

Mainstreaming Psychedelics: From FDA to Harvard to Burning Man
Google Tech Talk November 17, 2009 ABSTRACT Presented by Rick Doblin, Ph.D., Executive Director MAPS. We're now in the midst of a worldwide renaissance in psychedelic research, after decades of political suppression. Scientists from around the world will present their new findings at the largest psychedelic conference to take place in the US in 17 years, on April 15-18, 2010, in San Jose, CA (http://www.maps.org/conference/ ). Even media reports, which usually mention in passing the widespread use of psychedelics by the counterculture in the 1960s, are more hopeful than alarming. In this talk, we'll review the factors which led to the backlash and the lessons to be learned, discuss how the FDA opened the door to research around the world, how the ghost of Timothy Leary was buried at Harvard, and how Burning Man struggles to respond to people who have difficult psychedelic experiences. We'll conclude by explaining how non-profit drug development, initially of MDMA-assisted psychotherapy for postraumatic stress disorder (PTSD), can transform psychedelics into FDA-approved prescription medicines and can lay the groundwork for the successful, long-term integration of psychedelics into the mainstream of medicine, religion, art, creativity, and celebration. Rick founded MAPS in 1986. His dissertation [http://www.maps.org/dissertation/] (Public Policy, Harvards Kennedy School of Government) was on "The Regulation of the Medical Use of Psychedelics and Marijuana," and his masters thesis [http://www.maps.org/docs/doblin-mt.html] (Harvard) focused on the attitudes and experiences of oncologists concerning the medical use of marijuana. His undergraduate thesis [http://www.maps.org/research/cluster/psilo-lsd/goodfriday.pdf] (New College of Florida) was a twenty-five year follow-up to the classic Good Friday Experiment [http://www.maps.org/books/pahnke/index.html], which evaluated the potential of psychedelic drugs to catalyze religious experiences. He has also conducted a thirty-four year follow-up study to Tim Learys Concord Prison experiment [http://www.maps.org/news-letters/v09n4/09410con.html]. Rick studied with Stan Grof, M.D., and was in the first group to become certified as holotropic breathwork practitioners. His professional goal is to help develop legal contexts for the beneficial uses of psychedelics and marijuana, primarily as prescription medicines but also for personal growth for otherwise "healthy" people, and to also become a legally licensed psychedelic therapist. He resides in Boston with his wife and three children.

Save the Uranium-233, Explore Space, Save Lives
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).

Building Brains to Understand the World's Data
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.
