Last Friday, I attended the amazing Google Developer Day 2009! It’s a set of one-day developer events, and a very good chance to learn about latest products from engineers who built them, including Google Maps, OpenSocial, HTML 5, O3D, Android and the most exiting Google Wave! And this is the first time I have chance to talk and share my thoughs with Google developers.

At the keynote speech made by Kai-fu Lee, we learn about the latest products from Google and new features of existing products. There are two products I should pay my attention to, one is OpenSocial, the other is Google Map.

We have a project known as “FriendsMap.net”, helps you visualize where your contacts from Facebook via facebookr gem are located on the Google Map, we are planning to add Twitter via twitter auth, but it seems it’s hard to make facebookr and twitter auth work together compatibly. After a OpenSocial API lecture by Patrick Chanezon, I think OpenSocial is a better choice. OpenSocial is a common API for social applications across multiple websites, with this API we can bring more social network into our app and without learning how to build with every single one of them. The other techology we are using is Google Map. On Google Map lectures by Pamela Fox, I learn about the latest Google Map API V3, with many new features can greatly increase performance of our website. I ask Pamela a few questions about how much work will be needed in upgrading code V2 to V3 and drawing clickable hotspots on custom gmarkers. Her answer is quite funny and I become totally her fan after the conversation.

At the end, thank you Kudelabs offering me such a great opportunity, and all those who work with me on FriendsMap.net, thanks!
