This is the last Fridaygram of 2011, and like most everybody else, we’re in a reflective mood. It’s also the 208th post on Google Code Blog this year, which means we’ve averaged more than one post every two days, so that’s plenty of stuff for you to read. What did we write about?

At Google, we love to launch. Many of our posts were about new APIs and client libraries. We also posted a bunch of times about HTML5 and Chrome and about making the web faster. And we posted about Android, Google+, and Google Apps developer news.

Many of our 2011 posts were about the steady progress of App Engine, Cloud Storage, and other cloud topics for developers. We also published several times about commerce and in-app payments.

2011 was a stellar year for Google I/O and other developer events around the world. Some of our most popular posts provided announcements, details, and recaps of these events. And we welcomed a couple dozen guest posts during Google I/O from developers with cool stories to tell.

The two most popular Code Blog posts of the year were both launches: the Dart preview in October, and the Swiffy launch in June.

Last, and surely least, I posted 26 Fridaygrams in an attempt to amuse and enlighten you. Thank you for reading those, and thanks for dropping by and reading all the posts we’ve thrown your way this year. See you in 2012!

And finally, please enjoy one more Easter egg.

For developers and engineers, the best way to learn something is to get your hands dirty and try making something. That is why Google hosts many hackathons around the world. Last November 17 and 18, we had a bigger experiment at Gangnam (yes, this is the very Gangnam in Gangnam Style!) in Seoul, South Korea which expanded a 1-2 day hackathon into a much longer one which we called Google HackFair.



The idea was to give developers enough time (2 months) to develop something bigger and provide a nice chance to showcase their projects. 153 developers submitted 92 projects, and 40 projects were chosen from among them and displayed. Developers used many different technologies, including Android, Chrome, App Engine, and HTML5, and they completed creative and interesting projects: a remote controlled car guided by Android, a serial terminal for Chrome, a braille printer using Go, and many more!


Besides the exhibition, we also prepared a mini-conference and GDG (Google Developers Group) booth where Googlers and community developers gave 27 sessions in total.


More than 1000 people attended and enjoyed the Google HackFair. Although the event is finished, developers continue updating and polishing their projects. It was a great time indeed.

If you are interested in details for the projects including full demos or source code, please check here.


Soonson Kwon is Developer Relations Program Manager and Country Lead for South Korea. His mission is to help Korean developers make better use of Google’s developer products. He is also passionate about Open Source.

(Updated 10 Dec 2010 -- corrected link to 3rd Place Hilversum developer Kornel Lesinski's Twitter page.)

Last month, more than 50 developers assembled in Hilversum, Netherlands, and San Francisco, California for an HTML5 game jam.

The idea of HTML5 gaming may seem unusual, but if the results from this event are anything to go by, there will be plenty more HTML5 games in the future. In just over 24 hours of coding, attendees were able to produce the seeds of great games, powered by standard web technologies. The games we saw were novel, visually appealing, and in many cases, already very playable.

HTML5 is making it easy to develop games for standard web browsers, and it also provides a way for developers to reach mobiles and tablets with a single code base. Watch for other initiatives, like Mozilla's current HTML5 gaming competition, to take HTML5 gaming to the next level.

Here’s a look at the winners from both venues. You can see a detailed list of all the entries here.

First Place, San Francisco: Ninja Leap

A novel 8-bit style game where you “leap” over the bad guys. A good demo of the Canvas element and a complete game with levels and scoring. Congratulations David Ganzhorn and Mike Rotondo on winning the HTML5 Game Jam in the USA.

First Place, Hilversum: Monkey Fortress

A puzzle game where you build a fortress to protect the monkey, demonstrating a physics engine in Canvas. Congratulations Tom Hastjarjanto on winning the HTML5 Game Jam in Europe.

Second Place, San Francisco: Shell Shock

A platform shooter involving turtle-like creatures on wheels, using Canvas. By Wolff Dobson, Charles Lee, Nicolas Coderre, Dan Fessler, Sara Asher. (No online demo at present.)

Second Place, Hilversum: Snakes

A refresh on the classic “Snake” game, demonstrating multiplayer powered by NodeJS and WebSocket, and 3D transforms of the canvas element. By David Durman & Ales Sturala. (No online demo at present, but code repository available.)

Third Place, San Francisco: Fruit Link

A casual puzzle game by Bruno Garcia, where you link up adjacent matching fruit.

Third Place, Hilversum: Enterprise

A stunning 3D game inspired by the classic Syndicate series showcasing just how far we’ve come with Canvas-based graphics. Observe the collision detection and be sure to hit the “Flying Carpet” button as well as the space bar to fire! This game was also shown in the “Web or Native for Mobile Development?” session at the recent Google Developer Days conferences in Europe. Created by Kornel Lesinski, Peter van der Zee, and Edwin Martin.

A few other readily playable games you might enjoy are:

• Atome by Pierre-Louc Doulcet
• Tablet Tennis (multitouch) by Michiel van den Anker
• Scubed by David Gregory, Estelle Weyl, Gabe Hernandez, Perry Chow, Stacie Hibino
• Smiley vs. the Gumballs by Michael Yorg

We were also honoured to have keynotes by two pioneers of web-based gaming. In Hilversum, the speaker was Tino Zijdel, creator of DHTML Lemmings back in 2004. Tino, coincidentally a Hilversum local, explained the tricks he used to make the game playable on the browsers of the day. He has subsequently written his account of the Game Jam. It’s in Dutch, so here’s an English translation. There were additional presentations from from Yu Jianrong, who covered ten tips for HTML5 Game Development and Paul Irish on HTML5.

The San Francisco keynote was given by Marcin Wichary, who gave a keynote on games and HTML5. Marcin is the creator of the Pac-Man doodle and also the first version of the popular HTML5Rocks slides. Marcin talked about his experiences in recreating Pac-Man and the timeless aspects of videogaming in modern age, shared some behind-the-scenes trivia, and shared the technology used to write the doodle and debug it.

We thank SPIL Games for hosting and co-organising the Netherlands event, and we also thank Samsung for contributing a Galaxy Tab for the Game Jam at that venue. Developers working on touch apps were able to use the Tab for testing, and we later gave the device away as a prize. Congratulations all who took part!

Seo Master present to you: Update: Thanks for all the interest and feedback on 20 Things I Learned about Browsers and the Web! We hope to open-source the code in the coming months and will post an update when we do. Stay tuned.

Twenty years ago this month, Tim Berners-Lee published his proposal for the World Wide Web. Since then, web browsers and web programming languages have come a long way. A few of us on the Chrome team decided to write an online guide for everyday users who are curious about the basics of how browsers and the web work, and how their evolution has changed the way we work and play online. Called "20 Things I Learned about Browsers and the Web," this online guidebook is illustrated by Christoph Niemann, and built in HTML5, JavaScript and CSS3, with our friends at Fi.

In building an online book app, HTML5, JavaScript and CSS3 gave us the ability to bring to life features that hearken back to what we love about books with the best aspects of the open web: the app works everywhere, and on any device with a modern browser. Here are a few features of the book experience that we’re particularly excited about:

• After the app has been visited once, you can also take the experience with you offline, thanks to the Application Cache API.
• You can resume reading where you had left off as the book remembers your progress using the Local Storage API. We also mark the chapters that have previously been read by folding the top right corner of the page in the navigation.
• The app utilizes the History API to provide a clutter-free URL structure that can be indexed by search engines.
• The HTML5 canvas element is used to enhance the experience with transitions between the hard cover and soft pages of the book. The page flips, including all shadows and highlights, are generated procedurally through JavaScript and drawn on canvas.
• The canvas element is also used to animate some of the illustrations in the book.
• CSS3 features such as web fonts, animations, gradients and shadows are used to enhance the visual appeal of the app.

This illustrated guidebook is best experienced in Chrome or any up-to-date, HTML5-compliant modern browser. We hope you enjoy the read as much as we did creating it, at www.20thingsilearned.com or goo.gl/20things.
