Seo Master present to you: The high point of presenting Google Wave at I/O? The joy of seeing crazy smart developers react to the product and technology as we showed it publicly for the first time. The low point? Typing twephanie's Twitter password in clear text on the big screen (luckily, a team member reset it before anything questionable happened!). We had the chance to continue the Google Wave conversations through breakout sessions, which we are happy to now make available in the Google I/O series of videos now available online, and in office hours with the engineering team.

Douwe Osinga kicked off the series with a deep dive into the Google Wave APIs using demos and code samples to show how waves can be embedded into other sites as well as how to extend Wave with both client- and server-side code. After the wow of the chess gadget and the 'Rosy' robot demos during the keynote, developers flocked to the Programming with and for Google Wave session to learn how to start building extensions themselves. Notice how Douwe's good humor persevered through even tougher network problems than we had in the keynote.

The next session, Google Wave: Under the Hood, focused on core technologies behind Google Wave, diving into the heavy lifting we did in platform design to make it simple for developers to build concurrent applications. David Wang introduced the technology stack behind Google Wave's real-time collaboration and concurrency controls followed by an explanation of the operational transformation algorithms by Alex Mah. Dan Danilatos explained how the AJAX editor renders wave content and sends and receives fine-grained changes down to the level of keystrokes. Finally, Casey Whitelaw unveiled the natural language processing magic behind 'Spelly' our context-sensitive spelling system.

In the third and final session, Adam Schuck outlined the team's experience using Google Web Toolkit to build the Google Wave client. Adam went from GWT skeptic to zealous GWT advocate over the course of building Google Wave. In his talk, Adam covered some recent advances in GWT which enabled Google Wave to look and feel like a desktop application with comparable performance. He also discussed the use of WebDriver (an automated web testing tool) which is integral to the project's success.

We simply can't wait to see what developers build. Check out our docs on Google Code and request a developer sandbox account. For technical news and updates on the APIs and protocol, don't forget to bookmark the Google Wave Developer Blog .

Seo Master present to you: Google I/O was one of Android's biggest events of the year, with a Mobile track that focused primarily on all things Android, and 22 developers showcasing some of their great Android applications at the Google I/O developer sandbox.

For those of you who missed I/O or could not make all the Android sessions, we're excited to release session videos and presentations from the Mobile track online and free to developers worldwide.

At this year's I/O, we wanted to help developers further optimize their applications for the Android platform by creating better user experiences. Romain Guy explored techniques for making Android apps faster and more responsive using the UI toolkit. Chris Nesladek discussed the use of interaction design patterns in the Android system framework to create an optimal user experience. Since mobile application development is inextricably tied to battery performance, Jeff Sharkey provided an insightful look at the impact of different application features and functionalities on battery life. Taking the mobile experience further, T.V. Raman and Charles Chen discussed building applications that are optimized for eyes-busy environments, taking advantage of the Text-to-Speech library, as well as new UI innovations that allow a user to interface with the device without needing to actually look at the screen.

We also offered a few sessions on building compelling and fun apps that take advantage of the Android media framework and 2D and 3D graphic libraries. Chris Pruett discussed the gaming engine that he built and used as a case study to explain best practices and common pitfalls in building graphics-intensive applications. David Sparks lifted the hood on the infrastructure by diving into Android's multimedia capabilities and expanding on how to use them to write secure and battery-efficient media code.

We also had several sessions that meditate on challenges, best practices, and philosophies for writing apps for Android. Dan Morrill demonstrated multiple techniques for developing apps for Android in different scenarios, to help developers make the right decisions on the right techniques for writing their apps. Joe Onorato talked to developers about leveraging Android's ability to support multiple hardware configurations to make their applications run on a wide variety of devices without the overhead of building a custom version for each. Justin Mattson talked about advanced usage of Android debugging tools in his session and presented real-world examples in which these tools were used at Google.

Lastly, Robert Kroeger returns from the frontlines of launching Gmail Mobile Web for iPhone and Android's offline capabilities and shares the team's experiences in using a portable write-through caching layer running on either HTML 5 or Gears databases to build offline-capable web applications.

We hope these session videos and presentations are helpful to all Android developers out there. Don't forget to check out our newly announced Android Developer Challenge 2 - we look forward to seeing your passion, creativity, and coding prowess come together in the great apps you submit in this next challenge!
