Open Source at Google I/O 2017

One of the best parts of Google I/O every year is the chance to meet with the developers and community organizers from all over the world. It's a unique opportunity to have candid one-on-one conversations about the products and technologies we all love.

This year, I/O features a Community Lounge for attendees to relax, hangout, and play with neat experiments and games. It also features several mini-meetups during which you can chat with Googlers on a variety of topics.

Chris DiBona and Will Norris from the Google Open Source Programs Office will be around Thursday and Friday to talk about anything and everything open source, including our student outreach programs and the new Google Open Source website. If you're at Google I/O this year, make sure to drop by and say hello. Find dates, times, and other details in the Community Lounge schedule.

Google I/O 2011

Google I/O, Google’s largest annual developer conference, will take place May 10-11 in San Francisco at the Moscone West Convention Center. Many of the tracks will feature open source products: Android, Google Web Toolkit, Google Chrome, and several Google APIs.

Open Source Program Manager Chris DiBona will be hosting a Fireside chat with the Android team on Tuesday, May 10th from 2:30-3:30pm. Earlier that day, Open Source Team Member Josh Bloch will be presenting “Java Puzzlers - Scraping the Bottom of the Barrel” from 1:15-2:15pm. Check the recently announced Google I/O full schedule for more detailed information on this year’s sessions.

The event is completely sold out, but you can watch live streaming video of both keynote presentations on the Internet. New this year is Google I/O Extended, which gives developers who are unable to attend Google I/O the opportunity to watch the keynote and other major sessions live with their peers at free viewing parties around the world. For more Google I/O updates, check @googleio.

Google I/O 2010

Google I/O, Google’s largest annual developer conference, will take place on May 19-20 at Moscone West San Francisco, and nearly all of the tracks feature open sourced products -- Android, GWT, Chrome, Wave and Google APIs. We are very excited about the amount of content for open source developers this year.

Feel free to take a look at the full schedule that was recently announced. The event is completely sold out, but you can still catch the keynote presentations as they will be streamed live on the Google Developers YouTube Channel. You can also watch last year’s keynotes and session videos. Recordings from this year’s sessions will be posted on YouTube as well.

For those of you attending, Open Source Programs Manager Chris DiBona will be moderating a fireside chat with the Android team on Thursday, and he and members of the Open Source Programs Office will be present throughout the conference.

After many years of hard work from Googlers and the entire open source community, Chris DiBona is now ready to say, “Open Source is everywhere at Google I/O.”

Hope to see you there!

Web Storage Portability Layer: A Common API for Web Storage

As discussed in our Google Code Blog post on HTML5 for Gmail Mobile, Google's new version of Gmail for iPhone and Android-powered devices uses the Web Storage Portability Layer (WSPL) to let the same database code run on browsers that provide either Gears or HTML5 structured storage facilities. The WSPL consists of a collection of classes that provide asynchronous transactional access to both Gears and HTML5 databases and can be found on Project Hosting on Google Code.

There are five basic classes:

google.wspl.Statement - A parametrizable SQL statement class

google.wspl.Transaction - Used to execute one or more Statements with ACID properties

google.wspl.ResultSet - Arrays of JavaScript hash objects, where the hash key is the table column name

google.wspl.Database - A connection to the backing database, also provides transaction support

google.wspl.DatabaseFactory - Creates the appropriate HTML5 or Gears database implementation


Also included in the distribution is a simple note-taking application with a persistent database cache built using the WSPL library. This application (along with Gmail mobile for iPhone and Android-powered devices) is an example of the cache pattern for building offline web applications. In the cache pattern, we insert a browser-local cache into the web application to break the synchronous link between user actions in the browser and server-generated responses. Instead, as shown below, we have two data flows. First, entirely local to the device, contents flow from the cache to the UI while changes made by the user update the cache. In the second flow, the cache asynchronously forwards user changes to the web server and receives updates in response.

By using this architectural pattern, a web application can made tolerant of a flaky (or even absent) network connection!

We'll be available at the Developer Sandbox at Google I/O to discuss the cache pattern, HTML5 development and the WSPL library. Check it out! If you have questions or comments, please visit our discussion list.

Support for Mercurial Now Available for All Projects Hosted on Google Code

You may recall that we recently asked for help from some early testers of Mercurial on Project Hosting on Google Code. As of today, all of our Project Hosting users can make use of this added functionality. For full details, check out the Google Code Blog. Better still, if you happen to be joining us at Google I/O, stop by the Mercurial on Big Table Tech Talk to learn more.
