Google Tech Talk July 12, 2010 ABSTRACT Presented by Misko Hevery. If you are new to JavaScript and would like to understand how JavaScript works behind the scenes, than this talk is for you. We will look at the core philosophy behind JavaScript objects and how the primitives can be used to build up basic OO concepts such as Classes and what it means to instantiate an object. How functions are executed and the rules behind the "this" keyword and what it means to bind functions. How to think about the Asynchronous nature of non-blocking API and what it means for performance and testing.
This tutorial will cover the really basic things about JavaScript, mainly proper syntax of strings, method of script inclusion, and the commonly used alert() and document.write(). To those of a keen eye, you'll get a glimpse of my recent history at 1:33, and for that I apologize. "absolutely necessity": that should be "absolute." The error message display comes courtesy of Firebug, an incredibly useful Firefox add-on. The song is Beethoven's Ninth Symphony. (Those with epilepsy should stop watching this tutorial about ten seconds before its end to be safe...)
Google Tech Talk June 11, 2010 ABSTRACT Presented by Paul Bakaus. There are many professional game engines out there for consoles, PCs, and mobile handhelds. However, there is one big empty gap, even in 2010: Not a single game engine targets desktop and mobile browsers natively without the use of plugins. In this session, Paul will talk about the challenges of building a pure browser-based gaming engine, how web programming concepts like event-driven architecture need to be considered, and what it means to fully utilize the open web stack—HTML5, client- and server-side JavaScript, external Stylesheets, server-side JavaScript and, of course, Canvas—to squeeze every millisecond of rendering time. We will go into the details of our own upcoming Aves Engine for isometric real-time games and will give you a very solid idea of what needs to be done to build graphically rich, real-time, full featured games for the web. Paul Bakaus is the CTO of the Germany-based startup Dextrose AG, and his corporate work mostly focuses on UX, UI and tricky JavaScript challenges. He is best known for creating jQuery UI, the popular official UI framework for jQuery, where he was the driving force behind many of its plugins.
Google Tech Talk June 4, 2009 ABSTRACT Web Exponents: Speed Up Your JavaScript Presented by Nicholas C. Zakas. As an interpreted language, JavaScript is filled with hidden performance issues that conspire to slow down your code and ruin the user experience. Learn exactly what is fast, what is slow, and what you can do to squeeze that last bit of performance out of your JavaScript code. Nicholas C. Zakas is the author of Professional JavaScript for Web Developers, 2nd Edition (Wrox, 2009), co-author of Professional Ajax, 2nd Edition (Wrox, 2007), and a contributor to Even Faster Web Sites (O'Reilly, 2009). Nicholas is principal front end engineer for the Yahoo! homepage and is also a contributor to the Yahoo! User Interface (YUI) library. The Web Exponents Series is hosted by Steve Souders
Google Tech Talk July 28, 2010 ABSTRACT Presented by Ryan Dahl, the creator of the node.JS open source project. It is well known that event loops rather than threads are required for high-performance servers. Javascript is a language unencumbered of threads and designed specifically to be used with synchronous evented I/O, making it an attractive means of programming server software. Node.js ties together the V8 Javascript compiler with an event loop, a thread pool for making blocking system calls, and a carefully designed HTTP parser to provide a browser-like interface to creating fast server-side software. This talk will explain Node's design and how to get started with it.

Google Tech Talk May 18, 2009 ABSTRACT Presented by Mark Miller, Waldemar Horwat, and Mike Samuel. Slides for this talk are available from google-caja.googlecode.com Today's JavaScript is a decent language for writing small scale scripts. But even for beginners, it has too many minefields between what beginners learn and what they need to know. And JavaScript is now increasingly used for serious software engineering projects -- straining to carry a load it was not designed for. After 10 years, the world of JavaScript standards is moving again. The next version, EcmaScript 5, is in "final draft standard" status with implementations about to appear. The "Harmony" agreement sets the direction for future versions beyond EcmaScript 5. The "Secure EcmaScript" working group is working towards an EcmaScript 5 subset suitable for the security needs of inline gadgets, mashups, and more. In this first talk, we'll explain changes in EcmaScript 5, the problems they're meant to address, the de-facto standards they codify, and how these changes are likely to affect web applications. Waldemar Horwat has been involved with JavaScript standardization and implementation since the 1990's when he was working on Netscape's implementation. He is a former editor of the standard and wrote parts of the existing ECMAScript Edition 3 standard. He participates in the ECMA TC39 committee and is the Google representative at the ECMA General Assembly. Mark S. Miller is a research scientist at Google <b>...</b>

Google Tech Talk September 24, 2009 slides: www.slideshare.net Web Exponents: www.youtube.com ABSTRACT Presented by Chris Anderson. CouchDB's web API and offline replication capabilities make it ideally suited to power a sea-change in the relationships between users and service providers. I'll give a 10000 foot overview of CouchDB, as well as discuss the benefits and challenges of writing applications that can be replicated transparently from the cloud to local machines. Chris Anderson is an Apache CouchDB committer and co-author of the forthcoming O'Reilly book "CouchDB: The Definitive Guide". He is a director of couch.io, offering commercial hosting, support, consulting, and custom development. He enjoys working on JavaScript CouchApps which can be peer-replicated just like any other data. Chris is obsessed with bending the physics of the web to give control back to users.

In this 2007 presentation at Yahoo!, which is meant to be the beginning of a three-course sequence (followed by "Theory of the DOM" and then "Advanced JavaScript"), Douglas Crockford explores not only the language as it is today but also how the language came to be the way it is. Note: there's a title at the opening that claims this is "Part 1 of 4", but this video contains all four parts edited together. No need to go searching for the missing parts.

In this installment, I'll be covering JavaScript variables and how they're used, as well as going back and making sure you've got a thorough understanding of strings and their proper syntax. I apologize for the plethora (I think there are two, actually...) of grammatical mistakes that take place throughout (just one "page," actually...) the course of this tutorial. Bloody YouTube cuts off the last second of the video so the "red to white and back" effect doesn't deliver on its last promise.

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.

There are lies, damned lies, and benchmarks. Tuning language processor performance to benchmarks can have the unintended consequence of encouraging bad programming practices. This is the true story of developing a new benchmark with the intention of encouraging good practices.
