Developer: Some comments on Open source.If you consider to generate open source project, think about the type of open source license before publishing.GPL might not be the best choice as it disallow your code to be included within other nice projects when they are not licensed the same way.There are many other valid open source licenses (for example CDDL) which allow mixed licensing, even closed source parts.National contests might easy able disallow your Opensource software. In result pilots flight might not scored at WXC as well.You may ask yourself, what happen if my key to encrypt is public available as Open Source ?The answer on this is easy. You as a developer, made a wrong decision. GPL or CDDL doesn't mean, you have to publish your own used keys or passwords. You will simply still GPL the code, but simply obfuscate the key itself on the public repository. You may just write a README, how to use and compile the code, which will include the step to create a new private key.
