Modeling Application Usage Visually
Google engEDU
37 min – Apr 24, 2006

Google TechTalks
April 24, 2006

Scott Barber
Scott Barber is the CTO of PerfTestPlus, Inc. and Co-Founder of the Workshop on Performance and Reliability (WOPR). Scott’s particular specialties are testing and analyzing performance for complex systems, developing customized testing methodologies, group facilitation and authoring instructional materials.

ABSTRACT
Modeling application usage is more than just parsing log files and calculating page frequencies. Whether we are analyzing navigation path effectiveness, planning for scenario testing, documenting performance test workload models or mapping services or objects to user activity having a single, intuitive picture to reference makes the job easier.

In this session, we’ll explore a highly adaptable method for visualizing application usage and how to use this model to improve cross-functional team communication without requiring team members to invest time learning some new fad of a modeling language that they’ll probably never use again. This method references UCMLâ„¢ which has been described as "what collaboration diagrams should have been."

Ruby Sig: How To Design A Domain Specific Language
Google engEDU
1 hr 3 min – Oct 5, 2006

Google Tech Talks
October 5, 2006

David Pollak has been developing commercial software for 28 years. He founded Athena Design and wrote Mesa, the first real-time spreadsheet. David wrote Integer, the first online, collaborative spreadsheet. Since 2000, David has been developing domain specific languages for security and general web development.

ABSTRACT
David will describe a framework for developing DSLs which includes:

* Identifying the constituents in a development project;
* Determining the costs and benefits of a DSL for a particular constituency vs. hand-coding functionality for that constituency based on interviews and specs;
* Identifying the ‘thought leader’ in a given constituency and interviewing him or her to determine the semantics of the domain;
* Determining syntax of the DSL;
* Mocking up the DSL and ‘test driving’ it with the thought leader;
* Finding appropriate integration points for the DSL into the application;
* Defining the process by with the Domain Experts will update code in the DSL (e.g., they have a web page where they can change tax calculation rules vs. they make a change to particular Ruby files as part of a development/staging/production cycle.); and
* Iterate over the semantics, syntax, and process to fully integrate Domain Experts into the development process.

Thinking Beyond Borders
Google engEDU
33 min – Sep 27, 2007

Google Tech Talks
September 27, 2007

ABSTRACT

Our global society faces great challenges such as Global Warming, HIV/AIDS in sub-Saharan Africa, wide-spread hunger, and poverty. To effectively address these issues in years to come, we must re-envision how we prepare our next great leaders to be conscious agents of change. Thinking Beyond Borders is a 35-week program to educate Gap Year students about the economic, political, and cultural realities of our world while empowering them with the tools to create proactive social change. Through varied service learning opportunities, the itinerary immerses students in cultures and communities around the world to provide experiences with various issues of International Development. The curriculum challenges students to synthesize academic research and their collected observations into powerful conclusions about the nature of globalization, world hunger, human rights, cultural change, and political systems. The most unique aspect of this program is that students return to the US to meet with international policy makers and share their conclusions with student and philanthropy groups to raise awareness and funds for the NGOs they worked with abroad. In these ways, Thinking Beyond Borders seeks to create a community of conscious agents of proactive change, equipped to tackle our world’s greatest challenges.

Stanford Experts on Climate Change and Carbon Trading
Google engEDU
1 hr 42 min – Jan 27, 2006

Google TechTalks
January 27, 2006

Thomas C. Heller and Stephen H. Schneider

Abstract
Please join two distinguished Stanford Professors, Dr. Stephen Schneider and Professor Thomas Heller, for a discussion on climate change and the emerging carbon trading markets. Dr. Schneider is one of the world’s leading scientific experts of climate change (his name is cited on all those climate change charts and graphs we’ve seen so far). Dr. Heller has extensive experience with policy and negotiations surrounding climate change and sustainable development. Professor Heller also recently served as Sergey’s host at the recent UN Climate Change Conference meeting in Montreal where Prof. Heller proved his indepth knowledge of thenuances of legislative works, such as the Kyoto Protocol, and the mechanisms that are currently being employed.

This tech talk will be different than our previous climate change talks. These men have helped steered the international course of policy, scientific verifications and the overall consensus on the existence of climate change. They both have plenty to say about what the failures and successes have been along the way, and what their predictions for the future of climate change policy will be. Email me if you have any questions.

March 14, 2007

ABSTRACT

Design Patterns must be studied in the context on the language in which they’ll get implemented (the Gang of Four made that point very strongly in their book, though almost everybody else seems not to have noticed:-). This talk explores several categories of classic "elementary" DPs in a Python context — Creational, Masquerading, Adaptation, and Template.

Visual 3D modeling of real-world objects and scenes from images
Google EngEDU
1 hr 3 min – May 1, 2007

Google Tech Talks
May 1, 2007

ABSTRACT

Images and videos form a rich source of information about the visual world. The extraction of 3D information from images is an important research problem in computer vision and graphics. The ubiquitous presence of cameras and the tremendous advances of processing and communication technologies yields important opportunities and challenges in those areas.

My work has focused on developing flexible techniques for recovering 3D shape, motion and appearance from images. A first example of this is an approach to recover photo-realistic 3D models of static objects or scenes from videos recorded with a hand-held camera or on a moving vehicle. A key aspect of our approach is the ability to also recover the geometric and photometric calibration of the camera from the image data so that our techniques can also work with uncalibrated consumer cameras or archive photographs. Towards the end of my talk, I will also briefly discuss approaches to capture dynamic scenes, both from single and multiple cameras. Applications ranging from archaeology and 3D urban modeling, to special effects and 3D tele-medecine will be used to illustrate our work.

Zero Configuration networking with Bonjour
Google engEDU
1 hr 1 min – Nov 2, 2005

Google TechTalks
November 2, 2005

Dr. Stuart Cheshire, Apple Computer

http://www.stuartcheshire.org/

ABSTRACT
The desirability of making IP networking easy to use has been obvious for many years, but achieving that goal has proved elusive. One day, Stuart Cheshire got tired of fellow Stanford Computer Science PhD students wanting to print from his Mac (via AppleTalk) because they couldn’t work out how to configure their Linux /etc/printcap files to access the network printer they wanted to use via IP, and he decided it was time someone did something about it.

Thus began a long saga, beginning with the formation of the IETF "Zero Configuration Networking" working group, and ending where we are today, with widespread adoption of Stuart Cheshire’s Multicast DNS and DNS Service Discovery technology, or "Bonjour", as Apple likes to call it. Today just about every network printer from just about every printer vendor supports Bonjour, and ships with it enabled by default.

Stewart Smith
Stewart Smith works for MySQL AB as a software engineer working on MySQL Cluster. He is an active member of the free and open source software community, especially in Australia.

ABSTRACT
Part 1 – Introduction to MySQL Cluster The NDB storage engine (MySQL Cluster) is a high-availability storage engine for MySQL. It provides synchronous replication between storage nodes and many mysql servers having a consistent view of the database. In 4.1 and 5.0 it’s a main memory database, but in 5.1 non-indexed attributes can be stored on disk. NDB also provides a lot of determinism in system resource usage. I’ll talk a bit about that.

Part 2 – New features in 5.1 including cluster to cluster replication, disk based data and a bunch of other things. anybody that is attending the mysql users conference may find this eerily familiar.

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, and routing in networks.

William Pugh

ABSTRACT
I’ll talk about some of my experience in using and expanding static analysis tools for defect detection. The FindBugs tool developed at the Univ. of Maryland is now being widely used, including inside Google.

I’ll give an overview of FindBugs, show some of the kinds of errors we routinely find in production code, discuss the methodology we use for enhancing and expanding FindBugs and some of the recent additions to it, discuss ways of incorporating FindBugs into your development process (such as being able to get a report of all the warnings introduced since the last release of your software), and talk about the future of static analysis, including things such as a new Java JSR to provide standard annotations for things such as @NonNull and @Tainted.

Away with Applications: The Death of the Desktop
Google engEDU
1 hr 27 min – May 4, 2007

Google Tech Talks
May 4, 2007

ABSTRACT

The computer desktop metaphor is ubiquitous, but how much work do we get done there? None! Time is entirely wasted navigating or shuffling content to the application in which we can finally work. What lessons can we learn from designing interfaces without the desktop and without applications? Is it even possible? And how does this apply to the Web? Currently, Web applications are often more usable than their desktop-based counterparts because each one does one thing and does it well. Desktop applications used to be the same way, but over time — as applications grew to support the the users in the long tail — each became a complex portmanteau of all possible features. If we are not careful, our Web apps will suffer the same conglomerated fate. Mashups and services help to solve the problem on the development end by freeing functionality from any particular application. But, there is currently no way to offer that wealth of possible functionality to users in a scalable way. Would it be nice to embed a dynamic map into your Gmail message? Sure. A Flickr slideshow? Sure. But for Google to offer those in addition to the hundreds of other possible options, would clutter the interface beyond usability. What’s needed is a universal method of accessing functionality: a way of harnessing the power of services without the need for application developers to explicitly support them. I’ll be demonstrating such a method.

The talk demonstrates that a ZUI plus a universal method of accessing functionality spells the death of the application-centric computing model and the desktop-design paradigms.

Sowing the Seeds for a more Creative Society
Google engEDU
54 min – Oct 26, 2006

Google Tech Talks
October 26, 2006

Mitchel Resnick, Professor of Learning Research at the MIT Media Laboratory, develops new technologies and activities to engage people (especially children) in creative learning experiences. Resnicks Lifelong Kindergarten research group developed ideas and technologies underlying the LEGO Mindstorms and PicoCricket construction kits. He co-founded the Computer Clubhouse project, a network of after-school centers where youth from low-income communities learn to express themselves creatively with new technologies. Resnick earned a BA in physics at Princeton University (1978), and MS and PhD degrees in computer science at MIT (1988, 1992). Resnick has consulted throughout the world on the use of computers in education. He is author of Turtles, Termites, and Traffic Jams (1994), co-editor of Constructionism in Practice (1996), and co-author of Adventures in Modeling (2001).

ABSTRACT
In the 1980s, many people talked about the transition from the "Industrial Society" to the "Information Society." In the 1990s, people began to talk about the "Knowledge Society." But as I see it, we are now in a transition towards the "Creative Society." Success in the future (for individuals, for companies, for nations as a whole) will be based not on what we know or how much we know, but on our ability to think and act creatively. Unfortunately, current educational practices are woefully inadequate. In this talk, I will discuss new technologies and new educational initiatives designed specifically to help children develop as creative thinkers — so that they are prepared for life in the Creative Society. I will focus especially on two projects we are developing at the MIT Media Lab: (1) a new programming language, called Scratch, that makes it easier for kids to create animated stories, games, and interactive art — and share their creations with one another online ( http://scratch.mit.edu), and (2) a new breed of construction kit that combines art and technology, enabling kids to create musical sculptures, interactive jewelry, and other artistic inventions — and learn important math, science, and engineering ideas in the process. For more information, see scratch.mit.edu and www.picocricket.com and llk.media.mit.edu

Tyler Close

Visiting Scientist Hewlett-Packard Laboratories

Mr. Close is a researcher and developer, working in the field of secure, multi-user, distributed applications since 1998.

ABSTRACT
In Authorization Based Access Control (ABAC) systems built with object-capabilities, an access policy is expressed by the shape of a reference graph: what a user can do is determined by where they are in the reference graph and what other parts of the graph are reachable from that point. By applying some basic cryptography to create links that act as "webkeys", we can construct URL graphs that are compatible with today’s WWW infrastructure and additionally provide the properties of distributed capabilities. Webkeys enable users to achieve password-free fine-grain access control implicitly, simply by sending one another links to the pages they want to share. The webkey approach simultaneously provides developers with a powerful, and readily audited, access-control model.

In this talk, we’ll study the implementation of the CapWiki, which can serve as a private data space, a locally shared data space, a blog, and a wiki, simply by varying which links have been distributed to which people.

An Overview of the MySQL Engine and its Latest Features
Google engEDU
54 min – Apr 26, 2006

Google TechTalks
April 26, 2006

Timour Katchaounov

ABSTRACT
The first part of this talk describes the main principles behind MySQL’s query optimizer and execution engine, how the optimizer transforms queries into executable query plans, what these plans look like, and how they are executed.

The second part of the talk describes the major improvements in the query engine of MySQL 5.0, and how these improvements can benefit the users of MySQL 5.0. The "greedy" optimizer reduces compilation time for big queries with orders of magnitude. The "index merge" access method provides a way to use more than one index for the same query. For faster plan execution and to allow better join orders, the 5.0 optimizer transforms most outer joins into inner joins.

The outer joins that cannot be transformed into inner ones are executed in a pipeline manner, so that no intermediate results need to be materialized. Finally, some GROUP BY and DISTINCT queries can be executed much faster thanks to "loose index scan" technique that reads only a fraction of an index.

The talk concludes with the near-future plans for new features coming in the next versions of MySQL.

The game show format keeps you on your toes while the puzzles teach you about the subtleties of the Java programming language and its core libraries. Anyone with a working knowledge of the language will be able to understand the puzzles, but even the most seasoned veterans will be challenged. The lessons you take from this session are directly applicable to your programs and designs. Some of the jokes may even be funny. If you loathed Episodes I–V, you’ll detest Episode VI. Come early, because overripe fruit will, as usual, be given to the first 50 attendees. This is a repeat of a talk given at Google in May and at JavaOne 2007.

From Sound Synthesis to Sound Retrieval and Back
Google engEDU
55 min – Jul 10, 2007

Google Tech Talks
July 10, 2007

ABSTRACT

In this talk I will go over the technological and conceptual ties that exist between some of the current trends in sound generation for music and multimedia applications and the techniques for content based sound retrieval. This is because quite a number of the techniques being worked on for sound retrieval come from the field of sound synthesis and at the same time the new developments in retrieval are being applied and are inspiring new directions in the development of sound generation systems. To explain all this I will use examples from the research carried out in the Music Technology Group at the Pompeu Fabra University of Barcelona, Spain. In particular I will go over our research on spectral based concatenative synthesis and our work on sound and music retrieval. Also I will link it with the online community that we have developed for sharing sound files, Freesound http://freesound.iua.upf.edu, showing the potential that this open and shared resource has for the research on sound retrieval and for experimenting with new sound generation systems.

Tamara Munzner received a BS in 1991 and a PhD in 2000 from Stanford. Her current research interests are information visualization, graph drawing, and dimensionality reduction. She was the IEEE Symposium on Information Visualization Program/Papers Co-Chair in 2003 and 2004.

ABSTRACT
Information visualization, or infovis, is the interactive computer-based visual representation of abstract datasets. I will use collections of linked nodes as the launching point for a discussion of fifteen different approaches to infovis. Node-link graphs appear in many application domains, and people can perform many tasks faster or more effectively when they can manipulate a well-chosen visual representation of these graphs. A major challenge within infovis is how to handle the large datasets that occur in the real world. Designing algorithms with scalable speed and memory complexity is only part of the solution. The visual representation must also provide an appropriate abstraction, often requiring exploration across multiple levels of detail, to be comprehensible to the human in the loop. The talk will include examples in application domains ranging from web browsing to bioinformatics to computational linguistics, and datasets from thousands to millions of items.

Advanced Topics in Programming Languages Series: Parametric Polymorphism
Google engEDU
31 min – Apr 18, 2007

Google Tech Talks
April 18, 2007

ABSTRACT

Advanced Topics in Programming Languages Series: Parametric Polymorphism and the Girard-Reynolds Isomorphism. This talk is based on a series of papers by Philip Wadler, a principal designer of the Haskell programming language. Featured are a number of double-barreled names in computer science:

* Hindley-Milner (Strong typing without having to type the types)
* Wadler-Blott (Making ad-hoc polymorphism less ad-hoc with parametricity)
* Curry-Howard (Isomorphism between types and theorems, terms and proofs)
* Girard-Reynolds (Isomorphism between types and terms in the presence of parametricity)

The talk will conclude with a programming technique (using the above) where the Haskell compiler (almost) writes your code for you!

Using Fit: An Open-Source Testing Framework
Google engEDU
54 min – Feb 9, 2006

Google TechTalks
February 9, 2006

Rick Mugridge

Rick Mugridge is the lead author of the first book on storytests: "Fit for Developing Software". He has developed and is evolving FitLibrary to better support storytest driven development. He is a leading thinker and inventor in this area, and consults and coaches internationally in storytesting, executable specifications, and agile software development.

ABSTRACT
We raise four software development issues and show how Fit can be used to address them. The issues are as follows: (1) How can we improve test coverage on a legacy system without discouraging its evolution? (2) Now that we have a successful product with a great UI, how do we provide program access, such as through SOAP? (3) How can QA be involved earlier and more effectively? (4) How can product managers better utilise their expertise?

Each of these issues can be addressed with Fit storytests. Storytests satisfy the demands of both requirements and quality assurance, in an amalgam that initially looks weird and counter-intuitive. Storytests are concrete examples that express important things about the business domain and about the system. They are matched and generalised in the code, using the same "ubiquitous language". Week by week, as thinking and understanding grow and change, the storytests grow and change. And so the code evolves.
