class LimitedAdminInlineMixin(object):
    """
    InlineAdmin mixin limiting the selection of related items according to
    criteria which can depend on the current parent object being edited.

    A typical use case would be selecting a subset of related items from
    other inlines, ie. images, to have some relation to other inlines.

    Use as follows::

Locating the story: The latest in mapping

A collection of links for a NICAR 2012 presentation. It will suggest broad themes for the past year, and try to support them with examples from work in the field. This is a work in progress. Feel free to crap on it, or add your own ideas.

Escape from Google Maps

• Google changed the rules of the game. There are now usage limits. Read about them here
• TileMill, custom tiles, need examples
• Links to ranty blog posts from Nestoria guy and others
• One replacement is simple line maps drawn using HTML5 technologies like SVG, Canvas and VML. You saw this example a lot in election maps during the GOP primaries, like NYT, WaPo, HuffPo, LAT
