I did one of these DevCamps before, when it was online, and that was a lot of fun. I know that the general idea is that we get into teams and work on a project for the two days.
However, if anyone would like to know more about contributing changes to Moodle core, then I was wonding if it would be possible / desirable to fit in some shorter sessions about this. For example we could do something for the last half hour of one or both of the days. For example, we could have one session about writing code to Moodle's coding guidelines, and submitting your fix to the tracker. And/or we could have another session about the Peer review and integration reveiw processes.
If anyone thinks this would be interesting, then I can see from the people posting in this forum that we have several people at the DevCamp with a lot of experience of contributing to Moodle core, and we could do some sessions like this, if they fit in. (I suppose there could also be other topics, like Unit testing and Behat testing.)
