Wuala - a distributed file system

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

Quantum computing day 2: image recognition with an adiabatic quantum computer

Google Tech Talks December, 13 2007 ABSTRACT This tech talk series explores the enormous opportunities afforded by the emerging field of quantum computing. The exploitation of quantum phenomena not only offers tremendous speed-ups for important algorithms but may also prove key to achieving genuine synthetic intelligence. We argue that understanding higher brain function requires references to quantum mechanics as well. These talks look at the topic of quantum computing from mathematical, engineering and neurobiological perspectives, and we attempt to present the material so that the base concepts can be understood by listeners with no background in quantum physics. In this second talk, we make the case that machine learning and pattern recognition are problem domains well-suited to be handled by quantum routines. We introduce the adiabatic model of quantum computing and discuss how it deals more favorably with decoherence than the gate model. Adiabatic quantum computing can be understood as an annealing process that outperforms classical approaches to optimization by taking advantage of quantum tunneling. We also discuss the only large-scale adiabatic quantum hardware that exists today, built by D-Wave. We present detailed theoretical and experimental evidence showing that the D-Wave chip does indeed operate in a quantum regime. We report about an object recognition system we designed using the adiabatic quantum computer. Our system uses a combination of processing steps ...

Contributing with git

Google Tech Talks October 27, 2008 ABSTRACT Source code versioning is an invaluable tool for software development: - users can easily track the newest versions, - maintainers can easily track down which commit introduced a bug (often making it easier to come up with a fix), - new developers get more documentation than just a big chunk of source code, - etc In my talk I want to stress the importance of source code versioning in a related context: when contributing changes to an Open Source project, which is typically a moving target, it can take a few revisions of the patches until they are accepted. I present several scenarios and workflows, and describe how Git can help with them. Speaker: Johannes Schindelin Johannes studied mathematics with a strong bias to number theory, trying to stay away from applied science as far as possible. Failing, he went on to a software company, where he gave up after finding that code quality played a lower role than pure politics. So he went back to university (Wuerzburg, Germany) to get a PhD in neurogenetics, and after a brief stint at psychology (St Andrews, UK) he now works on image processing (MPI Dresden, Germany).

Factor: an extensible interactive language

Google Tech Talks October 27, 2008 ABSTRACT Factor is a general-purpose programming language which has been in development for a little over five years and is influenced by Forth, Lisp, and Smalltalk. Factor takes the best ideas from Forth -- simplicity, succinct code, emphasis on interactive testing, meta-programming -- and brings modern high-level language features such as garbage collection, object orientation, and functional programming familiar to users of languages such as Python and JavaScript. Recognizing that no programming language is an island, Factor is portable, ships with a full-featured standard library, deploys stand-alone binaries, and interoperates with C and Objective-C. In this talk, I will give the rationale for Factor's creation, present an overview of the language, and show how Factor can be used to solve real-world problems with a minimum of fuss. At the same time, I will emphasize Factor's extensible syntax, meta-programming and reflection capabilities, and show that these features, which are unheard of in the world of mainstream programming languages, make programs easier to write, more robust, and fun. Speaker: Slava Pestov Slava was born in the former USSR and emigrated to New Zealand at the age of 7. He moved to Ottawa, Canada when he was 18 to study for a Bachelors and Masters degree in Mathematics. He now resides in Minneapolis, Minnesota.

Artist talk with photographer jessica todd harper

Google Tech Talks December, 12 2008 ABSTRACT Jessica Todd Harper makes otherworldly photographic portraits of families and individuals that bring to mind both the religious intensity of Northern Renaissance artists and the quiet eroticism and tenderness of Andrew Wyeth's Helga pictures. She shoots film but works with the images in Photoshop, sometimes piecing together imagery much like a painter integrates drawings into a final painting. Her talk will address the technical side of her work as well the influence of iconic portraits from the history of Western Art. Harper's images have been widely exhibited, and discussed in publications ranging from the The New Yorker to the Frankfurter Allgemeine Zeitung. A 2008 NY Photo Festival award winner, a 2008 Lucie Award winner, and a 2005 selection from Photo District News' annual list of rising young stars to watch, Harper published her first book of photographs, Interior Exposure this year. Selected by O, The Oprah Magazine as a top book recommendation, Harper's appeal extends beyond the New York art scene. Speaker: Jessica Todd Harper Harper teaches at Swarthmore College and The International Center of Photography. She is represented by Cohen Amador Gallery in New York.

Liquid fluoride reactors: a new beginning for an old idea

Google Tech Talks February 19, 2009 ABSTRACT Slides for this talk are available at: www.slideshare.net Speaker: David LeBlanc David's Ph.d in physics was completed at University of Ottawa (1998) on high temperature superconductors. During this period, he developed a great interest to pursue both fission and fusion reactor design basics, which separately cumulated in a long term fellowship from the Canadian Fusion Fuels Technology Project (later ITER Canada) for his work on the use of high Tc superconductors in the fusion field and also work for Atomic Energy of Canada Limited on worldwide reactor design comparisons. Since then he has been teaching at the Carleton University physics department and continued his investigations primarily in the field of Molten Salt Reactors, also known as Liquid Fluoride Reactors. David founded Ottawa Valley Research Associates Ltd to expand these efforts and has completed a license agreement with a European firm with a goal of development of a new generation of Molten Salt Reactors.

Amdahl's law in the multicore era

Google Tech Talks February 6, 2009 ABSTRACT Over the last several decades computer architects have been phenomenally successful turning the transistor bounty provided by Moore's Law into chips with ever increasing single-threaded performance. During many of these successful years, however, many researchers paid scant attention to multiprocessor work. Now as vendors turn to multicore chips, researchers are reacting with more papers on multi-threaded systems. While this is good, we are concerned that further work on single-thread performance will be squashed. To help understand future high-level trade-offs, we develop a corollary to Amdahl's Law for multicore chips [Hill & Marty, IEEE Computer 2008]. It models fixed chip resources for alternative designs that use symmetric cores, asymmetric cores, or dynamic techniques that allow cores to work together on sequential execution. Our results encourage multicore designers to view performance of the entire chip rather than focus on core efficiencies. Moreover, we observe that obtaining optimal multicore performance requires further research BOTH in extracting more parallelism and making sequential cores faster. This talk is based on an HPCA 2008 keynote address. Speaker: Mark D. Hill Mark D. Hill (www.cs.wisc.edu is professor in both the computer sciences department and the electrical and computer engineering department at the University of Wisconsin--Madison, where he also co-leads the Wisconsin Multifacet (www.cs.wisc.edu ...

Podcars: using networking ideas to transport people.

Google Tech Talks November 20, 2008 ABSTRACT Podcars are car sized vehicles on guideways elevated over streets. Podcar systems have network topology where each pod is routed the fastest way from origin to destination. High capacity is achieved through short inter-vehicle distances. The direct travel to any destination results in high mean travel speeds, rivaled only by a car in uncongested streets. Podcars use electricity directly off the grid and are very energy efficient. The talk will give a broad description of the technology and the market situation and present a sample network for the Googleplex. Speaker: Bengt Gustafsson Bengt Gustafsson, CEO of Beamways, a Swedish startup developing a Podcar system. Bengt's background is in the software industry where he has developed novel user interface generators, language interpreters and database engines.

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.

Merb, rubinius and the engine yard stack

Google Tech Talks October 20, 2008 ABSTRACT In this talk we will explore a few of the open source projects we work on here at Engine Yard. I will give a detailed overview of the Merb web framework and what it brings to the table. We will also discuss Rubinius, an alternate ruby VM based on SmallTalk 80 blue book that also uses LLVM for low level optimizations. We will also explore the 'stack' we are working on at EY which includes our own variant of Gentoo linux as well as a full stack of software dedicated to running ruby applications as efficiently as possible. Merb, like Ruby on Rails is an MVC framework. Unlike Rails, Merb is ORM-agnostic, JavaScript library agnostic, and template language agnostic, preferring plugins that add in support for a particular feature rather than trying to produce a monolithic library with everything in the core. While trying to keep the core as minimal and clean as possible, this hasnt meant a sacrifice of features. Merb has a very comprehensive set of features, which are continually improving. Rubinius is a project to develop the next generation virtual machine for the Ruby programming language, drawing on the best virtual machine research and technology of the last 30 years. It implements the core libraries in Ruby, making a system easily accessible for development and extension. Rubinius is also an excellent platform for experimenting with cutting-edge technology like software transactional memory. Speaker: Ezra Zygmuntowicz Lead ...

How to be a tummler - designing for conversation

Google Tech Talks November 18, 2008 ABSTRACT Community evolves from conversation. And an evolved community inherently evolves the conversation. How do you create genuine conversation for many people that don't always know each other yet? How do you create conditions that encourage trust and cross-connections? How do you tummel or draw people out and build the collective energy? Innovative comedian Heather Gold explains basic differences between presentation and conversation and the assumptions underneath each. More entertainingly (and usefully) she demonstrates these ideas by creating a great conversation in the room so that all can feel the difference. Speaker: Heather Gold Im a nationally-touring comedian and playwright who makes authentic conversations happen. Ive known business and technology audiences since I began to work the web in 1995. I have a surprisingly respectable past working in strategy roles with many Internet start-ups, New Line Cinema, Knowledge Adventure, and Apple Computers first music group which pioneered webcasting. Smart, funny audiences at my Internet Roast inspired me to open source aspects of my show. I continue to mix theatre, stand-up and aspects of the Net to create interactive performance.

Tangible functional programming

Google Tech Talks November, 7 2007 ABSTRACT We present a user-friendly approach to unifying program creation and execution, based on a notion of "tangible values" (TVs), which are visual and interactive manifestations of pure values, including functions. Programming happens by gestural composition of TVs. Our goal is to give end-users the ability to create parameterized, composable content without imposing the usual abstract and linguistic working style of programmers. We hope that such a system will put the essence of programming into the hands of many more people, and in particular people with artistic/visual creative style. In realizing this vision, we develop algebras for visual presentation and for "deep" function application, where function and argument may both be nested within a structure of tuples, functions, etc. Composition gestures are translated into chains of combinators that act simultaneously on statically typed values and their visualizations. Speaker: Conal Elliott Most of my research is aimed at supporting the creation of interactive synthetic media content, including computer animation, human-computer interaction, images, 2D and 3D geometry, and programmable shaders. In all cases, I aim to preserve or improve on the flexibility and performance of mainstream programming approaches, while greatly simplifying the creation process. Synthetic media programs are almost always implemented in sequential, imperative (often object-oriented) languages. My ...

Geoengineering earth's climate

Google Tech Talks January, 7 2008 Emergency preparedness is generally considered to be a good thing, yet there is no plan regarding what we might do should we be faced with a climate emergency. Such an emergency could take the form of a rapid shift in precipitation patterns, a collapse of the great ice sheets, the imminent triggering of strong climate system feedbacks, or perhaps the loss of valuable ecosystems. Over the past decade, we have used climate models to investigate the potential to reverse some of the effects of greenhouse gases in the atmosphere by deflecting some incoming sunlight back to space. This would probably be most cost-effectively achieved with the placement of small particles in or above the stratosphere. Our model simulations indicate that such geoengineering approaches could potentially bring our climate closer to the state is was in prior to the introduction of greenhouse gases. This talk will present much of what is known about such geoengineering approaches, and raise a range of issues likely to stimulate lively discussion. Speaker: Ken Caldeira Ken Caldeira is a scientist at the Carnegie Institution Department of Global Ecology and a Professor (by courtesy) at the Stanford University Department of Environmental and Earth System Sciences.

Im2gps: estimating geographic information from a single image

Google Tech Talks August 5, 2008 ABSTRACT Estimating geographic information from an image is an excellent, difficult high-level computer vision problem whose time has come. The emergence of vast amounts of geographically-calibrated image data is a great reason for computer vision to start looking globally on the scale of the entire planet! In this paper, we propose a simple algorithm for estimating a distribution over geographic locations from a single image using a purely data-driven scene matching approach. For this task, we will leverage a dataset of over 6 million GPS-tagged images from the Internet. We represent the estimated image location as a probability distribution over the Earth's surface. We quantitatively evaluate our approach in several geolocation tasks and demonstrate encouraging performance (up to 30 times better than chance). We show that geolocation estimates can provide the basis for numerous other image understanding tasks such as population density estimation, land cover estimation or urban/rural classification. Speaker: James Hays James Hays received his BS in Computer Science from Georgia Institute of Technology in 2003. He has been a Ph.D. student in Carnegie Mellon University's Computer Science Department since 2003 and is advised by Alexei A. Efros.

Object capabilities for security

Google Tech Talks November, 30 2007 ABSTRACT Existing systems often do a poor job of meeting the principle of least privilege. I will discuss how object capability systems and language-based methods can help address this shortcoming. In language-based object capability systems, an object reference is treated as a capability; unforgeability of references ensures unforgeability of capabilities; and all privileges are expressed as capabilities in this way. This makes it possible to decompose the system into distrusting "privilege-separated" components, providing each component with the least privilege it needs to do its job; to reason about the privileges and powers available to various program elements, often in a local (modular) way; and to avoid common pitfalls, such as confused deputy and TOCTTOU vulnerabilities. I will attempt to introduce the audience to some work in this area that is perhaps not so widely known, and I will describe some work in progress to construct a subset of Java, called Joe-E, that is intended to enable capability-style programming using a programming syntax that is familiar to Java programmers. Speaker: David Wagner David Wagner is an Associate Professor in the Computer Science Division at the University of California at Berkeley with extensive experience in computer security and cryptography. He and his Berkeley colleagues are known for discovering a wide variety of security vulnerabilities in various cellphone standards, 802.11 ...

Kilim: fast, lightweight, cheap message passing in java.

Google Tech Talks June, 11 2008 ABSTRACT Kilim: Fast, lightweight, cheap message passing in Java. A million actors, 3x faster than Erlang. The message passing (MP) paradigm is often seen as a superior alternative to the typical mix of idioms in concurrent (shared-memory, locks) and distributed programming (CORBA/RMI). MP eliminates worries endemic to the shared-memory mindset: lock ordering, failure-coupling, low-level data races and memory models. It simplifies synchronization between data and control planes (no lost signals or updates), and unifies APIs for local and remote process interaction. Curiously however, there are no efficient frameworks for intra-process message-passing, except for Erlang. This talk describes a Java framework called "Kilim" to fix this state of affairs. Kilim provides: 1. Extremely lightweight user-level threads (actors) with automatic stack management, obtained via CPS transformation. 2. A simple type system that ensures actor isolation by controlling pointer aliasing in messages at compile time, and by ensuring linear ownership of mutable message objects. This permits safe, zero-copy communication. 3. A compact run-time library containing typed mailboxes (with optional flow control), user-definable scheduling and python style generators. Kilim is portable; one of our explicit goals was to not require changes to the Java language syntax or to the JVM. Kilim scales comfortably to handle hundreds of thousands of actors and messages on modest ...

Turing's cathedral

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.

If you had everything computationally where would you put it, financially?

Google Tech Talks May 5, 2008 ABSTRACT Technology has transformed investment and trading over the past 30 years. Markets have become computer networks, brokers are disintermediated by direct access and algo trading. Reporters are disintermediated when investors have access to primary sources at the same time they do. An ever larger view of exploitable economic and business activity can found on the web. Dr. Leinweber brings an unusually broad and deep view to these issues, from both a sell- and buy-side perspective. Speaker: David Leinweber David Leinweber is Haas Fellow in Finance. His professional interests focus on how moderninformation technologies are best applied in trading and investing. As the founder of two financial technology companies, and a quantitative investment manager he is an active participant in today's transformation of markets. He is an advisor to investment firms, stock exchanges, brokerages, and technology firms in areas related to financial markets , and a frequent speaker and author on these subjects. His book, "Nerds on Wall Street" will be published by Wiley in 2008. He graduated from MIT, in physics and computer science and also has a Ph.D. in Applied Mathematics from Harvard.

Using audio technology to reduce global illiteracy, poverty

Google Tech Talks January, 8 2008 ABSTRACT For more info, see literacybridge.org Knowledge is power; but most knowledge is tied up in text. So how do the 774 million illiterate adults in the world access knowledge crucial to preventing disease, creating economic opportunity, and defending their political and human rights? Cliff spent six weeks in a remote region of Ghana to understand rural poverty and sustainable development. He saw many impressive local organizations sharing valuable information for development; but he also experienced the inefficiency of delivering all this information in person. In response to this problem, Literacy Bridge was founded to empower children and adults with tools for scalable knowledge sharing and literacy learning. The Talking Book Project is Literacy Bridge's major program, developing new and affordable digital audio technology to provide vital, locally generated information and literacy training to people with limited access to either. Imagine a $5 iPod used to play locally generated podcasts, plus a decentralized, digital content distribution system that reaches villages without electricity but also enables global content sharing. Aside from the innovative use of technology, partnerships with local businesses, civic organizations, and government agencies play a pivotal role in the Talking Book Project. During this talk, Cliff will share his observations from Ghana and discuss Literacy Bridge's Talking Book Project. Speaker: Cliff ...

Microgrids: providing energy services locally

Google Tech Talks March 25, 2009 ABSTRACT Two stylized alternative visions of how the power system might evolve to meet future requirements for the high power quality and reliability (PQR) electricity service that modern digital economies demand will be contrasted, a supergrids paradigm and a dispersed paradigm. Some of the economics of the dispersed vision are explored, and perspectives are presented on both the choice of homogeneous universal power quality up-stream in the electricity supply chain and on the extremely heterogeneous requirements of end-use loads. The characteristics of one microgrid paradigm for providing heterogeneous PQR, the CERTS Microgrid, will be described. Microgrid demonstrations in the US and Japan will be highlighted. Finally, analysis of the economics of possible microgrid installations in California and New York states will be explained using some example buildings, including data centers Speaker: Chris Marnay Chris Marnay is Staff Scientist and Leader of the Technology Evaluation, Modeling, and Assessment Group at the Lawrence Berkeley National Laboratory.

Self-organization: the secret sauce for improving your scrum team

Google Tech Talks September 4, 2008 ABSTRACT High performance depends on the self-organizing capability of teams. Understanding how this works and how to avoid destroying self-organization is a challenge. Until you understand complex adaptive systems and how Toyota works it is difficult to improve team velocity. Jeff will discuss three core topics: 1. Shock therapy as a strategy for booting up teams. 2. The Cosmic Stopping Problem, otherwise known as the choice uncertainty principle. 3. Punctuated equilibrium - how software systems evolve Take advantage of these concepts and you may find a way to achieve the ultimate potential of a team. This session will be a "Deep Agile" presentation keying off topics presented to engineers at MIT. Speaker: Jeff Sutherland Dr. Jeff Sutherland is one of the co-creators of the Scrum software development process. He and Ken Schwaber invented Scrum in 1993. Since then he has worked with many software companies and IT organizations to extend and enhance this process. For more info please Google Jeff or visit his web site.

Git

Google Tech Talks October, 12 2007 ABSTRACT When you have hundreds of people simultaneously patching 25000 files of the Linux Kernel in sometimes conflicting ways, you might need some scheme or plan to sort all that out before you can build your next kernel and reboot. The Linux team uses "git" for their source code repository management, a homegrown solution that is optimized for highly distributed development, working with huge sets of files, merging independent work at multiple levels, and seeing who broke what. (Git has also since been notably adopted by the Cairo, x.org, and Wine teams, and is being transitioned to by the Mozilla codebase.) In my talk, I describe what "git"; is and isn't, and why you should use it instead of CVS, Subversion, SVK, Arch, Darcs, Mercurial, Monotone, Bazaar, and just about every other repository manager. I'll also walk though the basic concepts so that the manpages might start making sense. If I have time, I'll even do a live walkthrough, where you can watch how fast I make typos.
