I have been working on an application that relies heavily on work that people have contributed to the open source community. Specifically I created a neat application that I think will help me retain customers and continue to get new customers and might even allow me a little pricing power. The application was developed in Python and r...
We're looking into transport/protocol solutions and were about to do various performance tests, so I thought I'd check with the community if they've already done this: Has anyone done server performance tests for simple echo services as well as serialization/deserialization for various messages sizes comparing EJB3, Thrift, and Protocol...

I can't load it all into memory at once to pass to the .writestr method of ZipFile, and I really don't want to feed it all out to disk using temporary files and then read it back. Is there a way to feed a generator or a file-like object to the ZipF...
I am hoping to dynamically update a ModelForm's inline Meta class from my view. Although this code seems to update the exclude list in the Meta class, the output from as_p(), as_ul(), etc does not reflect the updated Meta exclude. I assume then that the html is generated when the ModelForm is created not when the as_*() is called. Is th...
