Seo Master present to you: By Dion Almaer, Google Developer Programs

Having the July 4th holiday smack in the middle of the week creates a strange week when it is hard to know which day it is. That being said, we have seen some interesting uses of our APIs, and we are happy to welcome a new team to Google.

In API and developer-product news...

Aleksander Fedorynski felt like "a penguin assigned to work on Herring Search" when he started building improvements to Google Code Search.

Alex Komoroske asked if you want spreadsheet filtering? and answers with a feature-rich auto filter that makes great use of the Spreadsheet Data API. Do a view source and see how it all works!

Mark Berghausen of the Search Quality Team has written a few words about the search considerations designers should think about when building a Flash-heavy site in: Best uses of Flash.

July 4th has gone, but the mashup is still here. Paul McDonald made it easy to find fireworks in your area, using the Google Mashup Editor. Speaking of which, Don Schwartz talks about how you can edit our mashup in whatever editor you choose.

Around Google

If you call 1-800-GOOG-411 you can now say "map it" and a map will be sent to you.

GrandCentral is now part of the team: "GrandCentral is an innovative service that lets users integrate all of their existing phone numbers and voice mailboxes into one account, which can be accessed from the web. We think GrandCentral's technology fits well into Google's efforts to provide services that enhance the collaborative exchange of information between our users."

Featured Projects

The Rocket GWT library provides the ability to define beans, properties, references and other Spring like concepts in GWT.

The Digg Roundup Gadget is a gadget based on the Digg Roundup tool, accompanied by a detailed "how-to" write up.

Seo Master present to you: The astute conference attendee would have noticed hidden QR codes around the conference, as well as the scannable QR codes on everyone's badge. We wanted to find a fun way for people to bond with their new phones, as well as network with other attendees, so we set about creating a scavenger hunt game using Google App Engine & Friend Connect. The app handled game logistics (a leaderboard, URL endpoints), and we printed up a bunch of custom QR code stickers that pointed to game URLs.

App Engine made writing the scavenger hunt app much easier than it otherwise would have been. The initial version of the app took one developer less than a day to turn out, and we continued to add functionality and tweak it as I/O approached and we tested it in real-world situations. The versioning deployment made it very easy to test and push out new versions without disrupting existing users.

The overall structure of the app was very straightforward: every QR-code had a unique URL, which was embedded into the generated QR code. A URL was associated with a number of points to be awarded and a destination URL (such as the user's profile information, in the case of a user's badge QR code). Users were signed in using Friend Connect, which allowed us to avoid concerns of authenticating users and managing sessions.

When a user visited a URL for the first time, we recorded that fact so they couldn't try and get extra points with repeat visits, then sent them to the destination URL. We also kept a running count of the user's score against the User entity, so as to not have to count up their points on every request. Generating the leaderboard was a simple matter of querying for the users with the most points and displaying them.

QR codes were generated using the Chart API, which simply takes a string of text and a few other parameters, and returns a fully formed QR code.

The three resourceful and persistent folks below beat out the competition to rise to the top of the scavenger hunt ranks - going to great lengths, including swag bribery, to gain points. A hearty (if belated) congratulations to the winners of the Google I/O mobile scavenger hunt!



1st Place - Abraham Williams
2nd Place - Waylon Flinn
3rd Place - Pete Richards


We hope everyone that participated learned how to use their Android phones a little better, met people they otherwise wouldn't have, and had some fun :)
