Tenth annual Code Jam competition wraps in London

Scientists at Google Labs have discovered it's not easy to be a great rock drummer. Your task is to devise an algorithm to audition drummers based on the imperfections of their rhythms.

This is the type of challenge that was posed to the finalists of our 10th annual Code Jam last week. Twenty-four of the world’s best coders were flown to London to compete for the title of Code Jam Champion 2013 and the accompanying $15,000.

Belarus's Ivan Miatselski, a.k.a. “mystic,” was crowned Champion, besting more than 45,000 other registrants and making it through four online qualifying rounds before winning the in-person finals. The final round was a four-hour, five-problem tour de code. Throughout Code Jam, contestants are allowed to use any programming language and any development environment they like, ranging from C++ to Taxi. And while the finalists are among the among the most talented, we’ve yet to see anyone earn a perfect score during the final round.

Successfully solving the problems involves more than just writing code: contestants in this year's finals needed mastery of computational geometry, dynamic programming, numerical algorithms and more. Though the competition is fierce, Code Jam is also a growing community of skilled problem-solvers, engineers and friends from all over the world. Code Jam will be back in 2014—join our community on Google+ and look for more news to come.

Live from Google I/O: Mo’ screens, mo’ goodness

This morning, we kicked off the 6th annual Google I/O developer conference with over 6,000 developers at Moscone Center in San Francisco, 460 I/O Extended sites in 90 countries, and millions of you around the world who tuned in via our livestream. Over the next three days, we’ll be hosting technical sessions, hands-on code labs, and demonstrations of Google's products and partners' technology.

We believe computing is going through one of the most exciting moments in its history: people are increasingly adopting phones, tablets and newer type of devices. And this spread of technology has the potential to make a positive impact in the lives of people around the world—whether it's simply helping you in your daily commute, or connecting you to information that was previously inaccessible.

This is why we focus so much on our two open platforms: Android and Chrome. They enable developers to innovate and reach as many people as possible with their apps and services across multiple devices. Android started as a simple idea to advance open standards on mobile; today it is the world’s leading mobile platform and growing rapidly. Similarly, Chrome launched less than five years ago from an open source project; today it’s the world’s most popular browser.

In line with that vision, we made several announcements today designed to give developers even more tools to build great apps on Android and Chrome. We also shared new innovations from across Google meant to help make life just a little easier for you, including improvements in search, communications, photos, and maps.

Here’s a quick look at some of the announcements we made at I/O:

  • Android & Google Play: In addition to new developer tools, we unveiled Google Play Music All Access, a monthly music subscription service with access to millions of songs that joins our music store and locker; and the Google Play game services with real-time multiplayer and leaderboards. Also, coming next month to Google Play is a special Samsung Galaxy S4, which brings together cutting edge hardware from Samsung with Google’s latest software and services—including the user experience that ships with our popular Nexus devices.
  • Chrome: With over 750 million active users on Chrome, we’re now focused on bringing to mobile the speed, simplicity and security improvements that we’ve seen on the desktop. To that end, today we previewed next-generation video codec VP9 for faster video-streaming performance; the requestAutocomplete API for faster payments; and Chrome Experiments such as "A Journey Through Middle Earth" and Racer to demonstrate the ability to create immersive mobile experiences not possible in years past.
  • Google+: We unveiled the newly designed Google+, which helps you easily explore content as well dramatically improve your online photo experience to give you crisp, beautiful photos—without the work! We also upgraded Google+ Hangouts—our popular group video application—to help bring all of your real-life conversations online, across any device or platform, and with groups of up to 10 friends.
  • Search: Search has evolved considerably in recent years: it can now have a real conversation with you, and even make your day a bit smoother by predicting information you might need. Today we added the ability to set reminders by voice and we previewed “spoken answers” on laptops and desktops in Chrome—meaning you can ask Google a question and it will speak the answer back to you.
  • Maps: Today we previewed the next generation of Google Maps, which gets rid of any clutter in order to put your individual experience and exploration front and center. Each time you click or search, our technology draws you a tailored map that highlights the information you need. From design to directions, the new Google Maps is smarter and more useful.

Technology can have a profound, positive impact on the daily lives of billions of people. But we can’t do this alone—developers play a crucial role. I/O is our chance to come together and thank you for everything you do.

We’re going live from Google I/O

Developers today have the power to introduce powerful, breakthrough technologies to the world through their code. That’s why we look forward to bringing Google developers together year after year at Google I/O, our annual developer conference. In one week, we’ll welcome more than 6,000 developers to I/O through the doors of Moscone West Convention Center in San Francisco, Calif.—and many more via our event’s live streams. If you’re looking for inspiration and want to learn more about the future of our products, we hope you’ll tune in to our live keynote and technical sessions.

Starting on May 15 at 9 a.m. PT (16:00 UTC), join us as Google Developers Live (GDL) powers multiple channels of live streamed content from Google I/O on developers.google.com/io. On this page, you can:

  • Stream the keynote on your computer, tablet or phone. Get in on the action, and listen to product and technology announcements straight from our teams. Live streaming will run on developers.google.com/io from 9 a.m. PT (16:00 UTC) to 7 p.m. PT (2:00 UTC) on May 15 and 16.

A new kind of summer job: open source coding with Google Summer of Code

If you’re a university student with CS chops looking to earn real-world experience this summer, consider writing code for a cool open source project with the Google Summer of Code program.

Over the past eight years more than 6,000 students have “graduated” from this global program, working with almost 400 different open source projects. Students who are accepted into the program will put the skills they have learned in university to good use by working on an actual software project over the summer. Students are paired with mentors to help address technical questions and concerns throughout the course of the project. With the knowledge and hands-on experience students gain during the summer they strengthen their future employment opportunities in fields related to their academic pursuits. Best of all, more source code is created and released for the use and benefit of all.

Interested students can submit proposals on the website starting now through Friday, May 3 at 12:00pm PDT. Get started by reviewing the ideas pages of the 177 open source projects in this year’s program, and decide which projects you’re interested in. Because Google Summer of Code has a limited number of spots for students, writing a great project proposal is essential to being selected to the program—be sure to check out the Student Manual for advice.

For ongoing information throughout the application period and beyond, see the Google Open Source blog, join our Summer of Code mailing lists or join us on Internet relay chat at #gsoc on Freenode.

Good luck to all the open source coders out there, and remember to submit your proposals early—you only have until May 3 to apply!

Cloud computing enabling entrepreneurship in Africa

In 2007, 33-year-old Vuyile moved to Cape Town from rural South Africa in search of work. Unable to complete high school, he worked as a night shift security guard earning $500/month to support his family. During the rush hour commute from his home in Khayelitsha, Vuyile realized that he could earn extra income by selling prepaid mobile airtime vouchers to other commuters on the train.

In rural areas, it’s common to use prepaid vouchers to pay for basic services such as electricity, insurance and airtime for mobile phones. But it’s often difficult to distribute physical vouchers because of the risk of theft and fraud.

Nomanini, a startup based in South Africa, built a device that enables local entrepreneurs like Vuyile to sell prepaid mobile services in their communities. The Lula (which means “easy” in colloquial Zulu), is a portable voucher sales terminal that is used on-the-go by people ranging from taxi drivers to street vendors. It generates and prints codes which people purchase to add minutes to their mobile phones.

Today, Vuyile sells vouchers on the train for cash payment, and earns a commission weekly. Since he started using the Lula, he’s seen his monthly income increase by 20 percent.

Vuyile prints a voucher from his Lula

Nomanini founders Vahid and Ali Monadjem wanted to make mobile services widely available in areas where they had been inaccessible, or where—in a region where the average person makes less than $200/month—people simply couldn’t afford them. By creating a low-cost and easy-to-use product, Nomanini could enable entrepreneurs in Africa to go to deep rural areas and create businesses for themselves.

In order to build a scalable and reliable backend system to keep the Lula running, Nomanini chose to run on Google App Engine. Their development team doesn’t have to spend time setting up their own servers and can instead run on the same infrastructure that powers Google’s own applications. They can focus on building their backend systems and easily deploy code to Google’s data centers. When Vuyile makes a sale, he presses a few buttons, App Engine processes the request, and the voucher prints in seconds.

Last month, 40,000 people bought airtime through the Lula, and Nomanini hopes to grow this number to 1 million per month next year. While platforms like App Engine are typically used to build web or smartphone apps, entrepreneurs like Vahid and Ali are finding innovative ways to leverage this technology by building their own devices and connecting them to App Engine. Vahid tells us: “We’re a uniquely born and bred African solution, and we have great potential to take this to the rest of Africa and wider emerging markets. We could not easily scale this fast without running on Google App Engine.”

To learn more about the technical implementation used by Nomanini, read their guest post on the Google App Engine blog.

Discover the world of open source with Google Code-in 2012

Every time you send a text, check a webpage or post a status update, you’re using open source software. The Internet is made of open source. But have you ever created any yourself? With the Google Code-in contest, pre-university students (13-17 years old) can learn more and create open source software that people all over the world can use—and win cool prizes along the way.

Starting Monday, November 26 and for the following 50 days, contest participants will work on fun online tasks for 10 different open source organizations. Possible challenges include documentation, marketing outreach, software coding, user experience research and more.

Participants earn points for each task they successfully complete and can earn prizes like T-shirts and certificates of completion. This year we’re doubling the number of grand prize winners to 20 talented students, who will win a trip to Google’s headquarters in Mountain View, Calif. They’ll spend a day getting a tour of the “Googleplex,” meeting and talking with Google engineers, plus enjoy another full day exploring San Francisco and other surprises.

Google Code Jam 2012 registration is open

Today, we're opening up registration for Google Code Jam 2012. This year thousands of students, professional programmers and freelance code wizards will pit their ingenuity against a new set of algorithmic challenges concocted by our tireless team of red-eyed, LED-illuminated problem writers.

Last year’s champion, Makoto Soejima, was asked to build a house for kittens, serve food to hungry mathematicians, escape from a shady casino and help Goro control his anger. Who knows what our problem writers have on their minds this year?

Code Jam is a world-wide programming competition in which contestants may use any programming language to solve algorithmic problems. The qualification round takes place April 13, followed by three online rounds in the following months. At the end of it all, the top 25 contestants will be invited to Google’s New York office on July 27 for a final match up and a chance to win $10,000. If you are up for the challenge, throw your hat into the ring now.
