Our meetups are always based on 5 - 10 minute lightning talks. You can hear lots of varied talks in one sitting and you don't need to work hard on a long 30 - 60 minute presentation to share something. No need for advance notice to give a talk. Chat after the talks to learn even more.
Share your projects or experiences and learn from others. Examples of topics we want to talk about include: programming languages, user experience, big data, mobile, hardware, web apps, operating systems, graphics, open source libraries, infrastructure, performance, security, productivity, etc. If you can loosely associate it with open source, it's probably good!
Come to Open Source, Open Mic to meet like-minded people, share your projects and learn from others. Food and drink provided.
