Sources of data

Bugzilla (full MySQL data dump available; talk to Josh for details)
- Interesting data: Comments, comment dates, comment authors, attachments (eg. code contributions), flag for first code contribution
mozilla-central or github
Mailing list archives of users who say they wish to write code for Mozilla
- For correlation with other pieces of data, usually

Interesting data to be mined

Contributors who are no longer active
- In progress, complete with ranking algorithm to prioritize prolific contributors
Mentoring effectiveness
- Bugs in bugzilla can have mentor=foo annotations; determine ratio of fixed to open bugs for mentor foo and dig into results (number of different people commenting in bugs, number of code contributions, how active mentor is, etc.)
Breakdown about volunteer activity across groups of components (such as Core: DOM and friends)
- Requires access to lists of employee names
Effectiveness of mentored bugs as stepping stone
- Figure out how many new contributors (ie. people whose first contribution was in 2012) contributed to at least one mentored bug and at least one non-mentored bug
