A modern technology for web components, the Web Experience Toolkit, had its second CodeFest.
The open source code and community are hosted on GitHub.
Government of Canada employees have played a substantial leadership role in the creation of the toolkit, in its release on GitHub, and in growing the community. It's a great example of government working in a modern way.
I've embedded links to the keynotes below, as well as a Storify of the event (I didn't attend, but I watched the keynotes on YouTube).
