Write an article for the Source!
The Kitware Source is a quarterly newsletter for developers designed to deliver detailed technical articles, information on recent releases and upcoming changes related to Kitware’s open source products. Kitware would like to encourage our active developer community to contribute to the Source. Contributions may include a technical article describing an enhancement you’ve made to a Kitware open-source project or successes/lessons learned via developing a product built upon one or more of Kitware’s open-source projects. Authors of any accepted article will receive a free, five volume set of Kitware books. Please send your ideas to firstname.lastname@example.org.
