PyCon 2013, occurring once again in sunny Santa Clara, California, will now be accepting all types of proposals through MONTH DAY, 2012. As with years past, we're looking forward to receiving your best proposals for tutorials, talks, and posters.

About PyCon 2013

The 2013 conference will run from XXXXXX to YYYYY at the Santa Clara Convention Center, just 15 minutes from San Jose, and one hour from San Francisco. On the schedule we have the main conference running Friday XXX through Sunday XXXXX, which is preceded by two days of tutorials and followed up by four days of sprints.

Continuing a trend started years ago, attendance records were once again broken last year, and the schedule was the best we've assembled. Can you help us top 2012?

Who Should Submit a Proposal?

Teeny-tiny GitHub API wrapper (just for the bits this app needs).

All that this does is expose a `requests.session` that makes it easy to
access GitHub, like so::

    >>> with github.session() as gh:
    ...     resp = gh.get('repos/django/django')
    ..      print resp.keys()

Upgrading auth.User - the profile approach

This proposal presents a "middle ground" approach to improving and refactoring auth.User, based around a new concept of "profiles". These profiles provide the main customization hook for the user model, but the user model itself stays concrete and cannot be replaced.

I call it a middle ground because it doesn't go as far as refactoring the whole auth app -- a laudable goal, but one that I believe will ultimately take far too long -- but goes a bit further than just fixing the most egregious errors (username length, for example).

This proposal includes a fair number of design decisions -- you're reading the fifth or sixth draft. To keep things clear, the options have been pruned out and on the one I think is the "winner" is still there. But see the FAQ at the end for some discussion and justification of various choices.
