This video is from the Open Source Developers’ Conference in Canberra, November 2011. The term patching is used in the hacker/programmer sense: you find a bug, figure out what’s going on, and fix (aka patch) it.
Apart from my lightning talks over the last three years, this is probably the first specific “bluehackers related talk”. For this reason I was actually a bit nervous beforehand, but it worked out very well. Those present found it fun and educational, with plenty of questions and chats triggered later – which is excellent. Feel free to talk more here in the comment thread!
Note: Yes, the video does show a prototype game board at the end. It was an unexpected spin-off during the talk preparation months ago, and I’ll post on that separately!
