One of the many talks at All Things Open 2015 this year will cover how you can contribute to open source while making a difference and have a lasting impact. The talk will be give by Guy Martin, director of open source strategy at Autodesk, and Nithya Ruff, director of open source strategy at SanDisk. Both have a wide range of experience in open source, from development to marketing, advocacy, and community. I caught up with them and asked them a few questions ahead of their talk: Many ways to move the needle in open source. In this interview, Guy and Nithya share what their first contributions to open source were, some advice they have for people starting out in open source, and more.
