What is the main focus of your initiative?
I choose something I think is achievable in ~1 hour and just have a go! I aim to highlight a different technology each week – last year I did C#, AngularJs, CSS, Lucene, markdown docs, and had a look at the maintainers side of open-source too. It’s supposed to be a learning experience, for me and the audience. I take extra care to articulate what I’m doing and thinking so the audience can follow along with the journey. It’s a lot harder than you’d think so I prepare the stream a bit beforehand to ensure it flows properly and to preempt any issues – it’s easier to talk through a problem when you’ve already solved it ;-)
