I'm sooo close... but I don't quite see the connection from the upload view to the model. When I use the callback in the model's FileField the upload works, but I'm not sure where the actual file copy is taking place. The goal is to make sure that chunking is happening, but the file copy action seems to be hidden somewhere? Here's what ...

I'm using Boost.Python to wrap a C++ library. How do I ensure that the same Python instance (by object identity) is always returned for a particular C++ instance (by pointer identity)? I can't extend the C++ classes, but I can add a member variable (such as a PyObject * or a boost::python::handle<>) if that helps. I'm thinking that I sh...

So far as I understand, a unicode string in Python should have the actual character, not the the UTF-8 encoding for the character...
Is there an article or forum discussion or something somewhere that explains why lists use append/extend but sets and dicts use add/update. I frequently find myself converting lists into sets and this difference makes that quite tedious so for my personal sanity I'd like to know what the rationalization is. The need to convert between ...
