Nordic.js is a two day conference that takes place in Stockholm in September. They're accepting proposals for talks, so you might want to bookmark that link if you're interested in speaking.
Tickets aren't yet available, but apparently a related meetup in Stockholm is extremely popular, so it'll sell out quickly.
Octocard (GitHub: zmmbreeze / octocard, License: MIT) is a GitHub widget, with a nice, compact design and a cool graph.
It's used by including a
<script> element with data attributes, and you can theme it fairly easily.
There's also a Node project called octocard-server that can serve data from MongoDB. It uses GitHub authentication, and the octonode GitHub API wrapper.
