Compiling and optimizing scripting languages

Google Tech Talks March 18, 2009 ABSTRACT Presented by Paul Biggar, Department of Computer Science and Statistics, Trinity College, Dublin. Scripting languages offer unique challenges to compiler writers. Challenges to compilation include undefined and changing language semantics, and run-time code generation. However, optimizing compilers face greater challenges still. Scripting languages offer many run-time features which are difficult to optimize, including run-time typing, run-time aliasing, run-time class and function definitions and run-time code generation. I discuss these problems, and a great number of their solutions, in relation to phc (phpcompiler.org), our optimizing ahead-of-time compiler for PHP.

Twitter wtf? - why is twitter called a threat to google?

Google Tech Talk April 30, 2009 ABSTRACT Presented by Laura Fitton Headlines alternately shout how Twitter is a Google Killer, and how it is a narcissistic flood of updates about what people you don't care about had for lunch. How can something that looks like noise from the outside be so compelling from the inside? Laura Fitton - @pistachio - will explain how microsharing on Twitter and similar services can make the web feel warm and human, can give you real-time information on what customers think of you and why she hasn't bought anything over $50 without asking Twitter first. With concrete examples, she'll show how Twitter has enabled large companies to gain sales and reduce support costs, how the famous have used it to cut out media misrepresentation, and how the Twitter platform has enabled a new class of web developers to take off fast. Laura @Pistachio Fitton Founder, Pistachio Consulting A vocal advocate for productive business uses of Twitter/microsharing, Laura re-launched Pistachio Consulting with that exclusive focus.

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.

Nyc tech talk series: javascript testing at google scale

Google Tech Talk (more info below) August 17, 2011 Presented by Cory Smith, Google Test Engineer. ABSTRACT Javascript is the defacto standard for rich application development on the web, supported by many browsers on many different platforms. Each day, more and more applications are being deployed over the web in a browser that rival desktop applications for interactivity and functionality. Examples of such rich applications include Google Maps, Google GMail, Google Docs, Hipmunk.com, and Angry Birds Chrome. However, Developing fast, robust, and high quality Javascript is a challenge within the industry. Unlike C++ or Java, the availability of high quality development, debugging, and testing tools for Javascript is still lagging industry standards. Inside Google, Javascript is the 4 largest language (in terms of lines of code) but one the fastest growing. It is key to all Google Web Applications (eg gmail, docs, etc.) Google has developed several unique tools to help address this issue, and make JavaScript developers more productive, both in developing and testing Javascript code. Come and hear how Cory Smith, the main engineer behind JsTestDriver, has approached the problem and what tools he developed for addressing some of these issues.

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).

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.

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.

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.

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.

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.

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 (www.maps.org ). 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.

Erlang

The programming language Erlang, new if even known at all to most computer programmers, secretly celebrates its 20th birthday year 2007. Erlang was developed with goals such as high-availability, "prototypeability"/maintainability and scalability over an at design time unknown number of CPUs. All goals are still challenges in software development. The scalability property has however reached another dimension due to the past few years development in the field of common and affordable multi core processors. This talk will cover the history of Erlang, demonstrate major design goals with a few programming examples and also touch on the subject of the future of Erlang. The speaker, Mr Lennart Ohman,...

Routing without tears; bridging without danger

Google Tech Talks April, 24 2008 ABSTRACT Why is route calculation done at both layers 2 and 3 of networking? Is one better? Do we need both? This talk explains the historical accident by which bridging was conceived and the properties that make it attractive, as well as dangerous, today. The talk discusses new work being done in IETF known as TRILL (TRansparent Interconnection of Lots of Links), which combines the advantages of bridges (layer 2 forwarding devices) and routers (layer 3 forwarding devices). Although the basic idea is fairly simple, certain properties of bridges, such as their ability to create partitioned VLANs on a layer 2 cloud, make the design challenging. Speaker: Radia Perlman Dr. Radia Perlman is a Fellow at Sun Microsystems, working on network and security protocols. She invented many of the basic algorithms that make today's network infrastructure robust and scalable. Her current research interests include assured delete, making large networks robust against Byzantine failures, and replacing bridges/switch with technology which is upwardly compatible, but more robust, flexible, and scalable. She is author of "Interconnections: Bridges, Routers, Switches, and Internetworking Protocols", and coauthor of "Network Security: Private Communication in a Public World", which are widely used both as textbooks in universities and for engineers to learn the field.

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.

Algorithmic mechanism design

Google Tech Talks August 15, 2007 ABSTRACT One of the challenges that the Internet raises is the necessity of designing distributed protocols for settings where the participating computers are owned and operated by different owners with different goals. Over the last decade or so there has been much research that aims to address these issues using ideas taken from the micro-economic field of mechanism design. In this talk I will survey the current state of the field: how mechanism design is applied in computational settings, how far can classical ideas go, and what are the challenges for further research. Among the applications discussed will be combinatorial auctions, cost sharing, scheduling,... Category: Howto & Style Length: 00:42:41.250 Tags: .

The openonload user-level network stack

Google Tech Talks February, 7 2008 ABSTRACT The architecture of conventional networked systems has remained largely constant for many years now. However, some specialised application domains have adopted alternative architectures. For example, the HPC community uses message passing libraries which perform network processing in user-space in conjunction with the features of user-accessible network interfaces. Such user-level networking reduces networking overheads considerably without sacrificing the security and resource management functionality that the operating system normally provides. Supporting user-level TCP/UDP/IP networking for a more general set of applications poses considerable challenges, including: intercepting system calls, binary compatability with existing applications, maintaining security, supporting fork() and exec(), passing sockets through Unix domain sockets and advancing the protocol when the application is not scheduled. This talk presents the OpenOnload architecture for user-level networking. We describe our solutions to the challenges outlined above, and novel techniques to reduce CPU overhead, avoid lock contention, minimise interrupt overheads and improve cache efficiency. Finally we present performance results of the OpenOnload stack including protocol compliance, and plans for further work within the open source community.

Aging of the other genome: a decisive but ambitious solution

Google Tech Talks December, 19 2007 The DNA in our cells consists of not only the well-known 46 chromosomes currently receiving such avid attention from specialists in sequencing technology, but also a large number of copies of a relatively tiny, circular DNA molecule inside the "powerhouse of the cell," the mitochondrion. Among other things, mitochondria perform the chemistry of breathing - they extract energy from nutrients by exquisitely regulated chemical reactions that consume oxygen and create CO2. This vital function depends on the 13 proteins encoded by the mitochondrial DNA (mtDNA), as well as on hundreds of proteins that are encoded in our more famous genome and imported across the mitochondrial surface after construction in the body of the cell. The mtDNA accumulates mutant, non-functional variants far faster than our main genome, so 20 years ago scientists began looking at the idea of putting copies of the 13 genes of interest into the nucleus after making modifications that would cause them to be processed by the same "protein import" machinery that processes the mitochondrion's many other proteins, thus making the mtDNA itself superfluous and mutations in it harmless. I will discuss this concept in detail in my talk. Progress has been very erratic in the meantime but is now very rapid, partly because of Methuselah Foundation-funded research. However, this approach may still prove impossible, so many other, ostensibly simpler ideas - some more ... Category: Science & Technology Length: 00:46:49.500 Tags: techtalk engedu education .

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 ...

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. I also work in one-to-many mediums: I wrote Alan Cummings material as the host of the Webbys and provide commentary for media like the San Jose Mercury News, TheStreet.com and CBC Radio. Much to my parents delight, I have degrees from Yale and ... Category: People & Blogs Length: 00:40:54.750 Tags: techtalk engedu education .

Algorithms for data management and migration

Google Tech Talks January, 23 2008 ABSTRACT I will describe some algorithms for addressing some fundamental optimization problems that arise in the context of data storage and management. In the first part of the talk we will address the following question: How should we store data in order to effectively cope with non-uniform demand for data? How many copies of popular data objects do we need? Where should we store them for effective load balancing? In the second part of the talk we will address the issue of moving data objects quickly, to react to changing demand patterns. We will develop approximation algorithms for these problems. The first part of the talk is joint work with Golubchik, Khanna,Thurimella and Zhu. The second part is joint work with Kim and Wan.

Impulse-based ultra-wide-band (uwb) radio systems and applications

Google Tech Talks May 22, 2008 ABSTRACT The old idea of impulse radio dates back to Marconi's first wireless transmissions using sparks. Unlike most wireless today, impulse radio transmissions are extremely wideband signals. The recently FCC- released frequency band from 3.1GHz to 10.6GHz is the widest unlicensed frequency band ever released (7.5GHz). This ultra wide bandwidth (UWB) is commercially explored for even faster data transfer using traditional, multi-band (OFDM) RF techniques. However, the available bandwidth is wide enough for impulse radio transmission giving new functionality and new implementation challenges. In this talk I will show how power efficient impulse radio solutions are feasible in standard digital CMOS technology. Quite non-standard and untraditional design strategies must be used including time-domain signal processing. Circuit topologies for higher order Gaussian pulse generation and power efficient, correlating RAKE receivers will be explained. Impulse radio transmissions have additional interesting properties compared to narrowband modulation. With time-domain processing (TDOA) highly accurate positioning is feasible in the millimeter range. Improved sensitivity for robust communication. Large number of channels (greater than 100). Novel applications are also feasible using impulse transmission. Combining novel design techniques like "Swept-Threshold sampling" and digital lossless integration, micropower impulse radar is feasible in CMOS. A ...
