By Fred Sauer, Developer Advocate Cross-posted with the Google Web Toolkit Blog Angry Birds for Chrome was updated to use the Web Audio API for all its in-game audio for Chrome users, which means Chrome users get the full Angry Birds experience, without any plugins. The Web Audio API supports a wide variety of use cases , including the high fidelity and low latency requirements of games. Users of other supported browsers will still get sound via Flash or HTML5 audio.seen or heard , Angry Birds was in no small part made possible by the cross-platform open source PlayN library. When building for the HTML platform, PlayN in turn relies heavily on Google Web Toolkit (GWT) to delivery a highly optimized web experience for users, and on gwt-voices to easily deliver a cross-browser audio experience.Web Audio API , Flash , HTML5 Audio , or even native audio. Your mileage will vary by browser and platform and which plugins you have installed. Also, gwt-voices will select the best available fallback, if the desired audio API is not going to work at all in your environment.Web Audio API tutorial and don't let those pigs grunt too much.Fred Sauer is a Developer Advocate at Google where most of his time is devoted to Google App Engine and Google Web Toolkit. He is the author of various GWT related open source projects including gwt-dnd (providing in browser Drag and Drop capabilities), gwt-log (an advanced logging framework) and gwt-voices (for cross browser sound support). Fred has dedicated much of his career to Java related development, with an increasing focus on HTML5.Posted by Scott Knaster , Editor

By Scott Knaster, Google Code Blog Editor making TCP faster through various proposals and experiments. Yesterday, Roberto Peon and Will Chan blogged about SPDY (pronounced speedy ), Google’s protocol for speeding up the web’s application layer historically handled by HTTP. In related news this week, the chairman of the HTTPbis Working Group announced support for SPDY in a public post .Make the Web Faster site . For example, there are articles on compression, caching, metrics, and more , a set of tools for measuring and optimizing pages , and several discussion forums for communicating with other interested folks .studying the yellow fattail scorpion , which uses bumps on its back to resist damage from sandstorms. Researchers hope to use the scorpion’s design to create erosion-resistant surfaces for blades, pipes, and similar parts. Or maybe they’ll make machines that look like giant yellow scorpions.NASA’s latest "Blue Marble" images of our planet. We have a beautiful home.Let’s say this fast: Fridaygram posts are just for fun.

By Roberto Peon and Will Chan, Software Engineers Cross-posted with the Chromium Blog SPDY , we’ve been working with the web community on evolving the spec and getting SPDY deployed on the Web. added SPDY support , which means that soon half of the browsers in use will support SPDY. On the server front, nginx has announced plans to implement SPDY , and we're actively working on a full featured mod-spdy for Apache . In addition, Strangeloop , Amazon , and Cotendo have all announced that they’ve been using SPDY. best practices document can also help website operators make their sites as speedy as possible. here , with slides here .Roberto Peon and Will Chan co-lead the SPDY effort at Google. Roberto leads SPDY server efforts and continues to tell people to be unafraid of trying to change the world for the better. Will works on the Chrome network stack and leads the Chrome SPDY efforts.

By Yuchung Cheng, Make The Web Faster Team several dozen parallel TCP connections ahead of making actual requests. This strategy overcomes inherent TCP limitations but results in high latency in many situations and is not scalable.Increase TCP initial congestion window to 10 (IW10) . The amount of data sent at the beginning of a TCP connection is currently 3 packets, implying 3 round trips (RTT) to deliver a tiny 15KB-sized content. Our experiments indicate that IW10 reduces the network latency of Web transfers by over 10%.Reduce the initial timeout from 3 seconds to 1 second . An RTT of 3 seconds was appropriate a couple of decades ago, but today’s Internet requires a much smaller timeout. Our rationale for this change is well documented here . research paper and internet-draft address concerns such as dropped packets and DOS attacks when using TFO.PRR , a new loss recovery algorithm, retransmits smoothly to recover losses during network congestion. The algorithm is faster than the current mechanism by adjusting the transmission rate according to the degree of losses. PRR is now part of the Linux kernel and is in the process of becoming part of the TCP standard .http://code.google.com/speed/ for further information.Yuchung Cheng works on the transport layer to make the Web faster. He believes the current transport layer badly needs an overhaul to catch up with other (networking) technologies. He can be reached at ycheng@google.com . Posted by Scott Knaster , Editor

By Navneet Joneja, Product Manager Google Cloud Storage is a robust , high-performance service that enables developers and businesses to use Google’s infrastructure to store and serve their data. Today, we’re announcing a new feature that gives you greater control over concurrent writes to the same object, and the availability of an App Engine Files API that makes it easier to read and write data from Java App Engine applications.Write concurrency control version-based concurrency control . Every time you update an object, it gets assigned a 32-bit, monotonically increasing sequence number. This version number is returned as a header with every GET or HEAD request. You can then use a conditional write operation to manage concurrent updates to the object (for example, when you want read-modify-write semantics). This feature is currently experimental.AppEngine Files API for Java applications announced the ability to read and write your Google Cloud Storage data using the App Engine Files API for Python applications. Today, we’re making the Files API available to Java App Engine applications too. This feature is currently experimental, and we’ll continue to enhance it in the months to come.discussion group .

By Raph Levien, Engineer, Google Web Fonts our rapid user adoption . Today, we are announcing a new way to make web fonts smaller and faster, in collaboration with the Monotype Imaging Fonts.com Web Fonts team. Google Web Fonts now implements Monotype Imaging’s MicroType Express compression format, which yields an approximate 15% savings in file size over using gzip alone. This change will automatically speed up Google Web Fonts for Internet Explorer browsers (version 6 and up). We’re also actively working to offer improved compression with other modern browsers, including Google Chrome.previous speed optimizations as well, such as automatically stripping the hints (metadata used for improving rendering quality on Windows) when serving fonts to Mac, iOS, and Android clients. We expect that most future optimizations will also be automatic and transparent.MicroType Express available to the public at no cost; the license can be found at monotypeimaging.com/aboutus/mtx-license . We believe it’s friendly to both open source and proprietary implementations. sfntly library, adding to the existing WOFF compression. The sfntly library, developed by the Google Internationalization Engineering team, serves as the core conversion engine in Google Web Fonts for subsetting, hint stripping, and related functions of our dynamic serving path. We hope that all web font services, as well as people hosting their own web fonts, will use sfntly to optimize font serving across the web.Raph Levien is an expert on fonts and graphics technologies.
