This month’s cover feature is Creating a Collection Manager with
Elixir, by Gaëtan de Menten. You have heard about SQLAlchemy, but never
found the time to actually try it? Or maybe you have heard about the
add-on to SQLAlchemy called Elixir, but don’t really know what it is

JC Cruz continues his series of articles on using Python to create
applications for Mac OS X. In the last article, you learned how to edit
data with the NSTableView. This month, in Table Drag and Drop with
PyObjC, you will learn the mechanics behind drag-and-drop and how to
support it in a table.
If you’ve ever done extensive development in Django, you’ll know the

Beginning this month, we are proud to present the column, Ask the
Pragmatic Testers, written by Titus Brown and Grig Gheorghiu. Both
Titus and Grig have a wealth of development experience, and we’re
excited to add them as regular contributors to the magazine. Many people
think that automated testing is about making sure your software works
right. They’re not wrong, but in Why test? It’s about complexity.
Titus and Grig remind us that there are deeper benefits – in
particular, managing the complexity of the build and development
This month Steve Holden ponders on the Zen of Python, sometimes with
less relevance that might be expected.
And in What does Python 3.0 mean for you?, I talk about the
reactions to the long-awaited release of Python 3.0, that came on
December 3, 2008. This is a big step forward in the evolution of Python,
