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.

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.”

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.

Last year, 542 students from 56 countries and 360 schools completed 3,054 tasks during the eight-week contest. This year we want to encourage even more students to participate in the contest and learn about open source development. If you’d like to sign up, please review our Frequently Asked Questions and the contest rules on our program site. You can also watch our screencast, check out some sample tasks from last year’s contest and join our discussion list for any other questions. For details on important dates for the contest, see the timeline. You can register for your account on the program site when the contest opens on Monday, November 26 at 9:00am PST.

Finally, our Open Source Programs team will be hosting a Hangout on Air on the Google in Education page November 26 at 2:00pm PST to discuss the details of the Google Code-in contest and answer any questions.

We hope you’ll spend your winter (or summer, for our friends in the southern hemisphere) learning about the ins and outs of open source development through hands-on experience. Ready...set...

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.
