Challenge of the Month — a programming challenge for S60 developers

Welcome to Forum Nokia's Challenge of the Month, a competition for S60 developers. Month after month we present new programming challenges — and you have new opportunities to distinguish yourself as a developer with a winning solution.

The challenges and the rewards

Architecture and usability play an essential part in how entries are judged. The Challenge of the Month competition isn't just about demonstrating a use case or creating a proof of concept. Focus on the idea that your solution might soon be used by a wide range of developers to extend the features of their applications beyond current limits.

Each winner will receive a set of valuable rewards:

• A brand-new S60 phone of the winner's choice.
• A winner's profile, published here on the Forum Nokia Web site, which acknowledges the winner as a recognized member of the S60 developer community.
• A Forum Nokia technical support package that will help in future S60, Series 40, and maemo™ development challenges.

This month's challenge

This month's competition is all about business. In this case, "business" refers to any productivity application (no games). What we're looking for is "time-savers" instead of "time-wasters." The more creative, the better.

Create a business application with KuneriLite and win a new mobile device of your choice.

KuneriLite is an innovative Rapid Application Development (RAD) toolkit for extending capabilities of Flash Lite from Adobe and creating S60 applications faster, easier, and cheaper. It enables Flash Lite developers to go beyond Flash Lite development without any knowledge of Symbian programming.

The following is a list of currently implemented KuneriLite plug-ins:

• Accelerometer.
• Camera.
• Connect.
• DTMF.
• File system.
• GPS.
• Rotate.
• Simple protection.
• System.
• Timer.
• Upload/Download.

Think of new and innovative ways to utilize GPS or sensor data, spice it up with a cool, flashy UI, and you could have a hit!

Use any combination of plug-ins, utilize the information in your Flash Lite application, and submit your application today.

Previous winners

January-Februay - Vassilis Legakis
In creating his winning entry for Forum Nokia's Challenge of the Month, Legakis was guided by the vision of visually rich applications running on top and robust C++ engines working in the background. Other approaches had led to solutions that were slow and had limited capabilities. Legakis started the HTTP-server approach by using Python scripting for complete HTML serving, but performance was an issue and the component started to grow dangerously large for what was designed to be a relatively light plug-in. Thus, Legakis came up with this simple, fast, and lightweight solution of simple command-parameters exchange, which is efficient for most applications of this type.
