Interactive Stacked Bar Chart using MatplotLib python

I have one process who's reading from a file (using file.read()) and one process who's writing to the same file (file.write()). The problem is it doesn't work - I get no errors but they can't operate at the same time. I've tried making the read and write operations none-blocking and then flushing the stream, as follows: fcntl.fcntl(file...

How do I debug code that segfaults unless run through gdb?
That's a single threaded code. In particular: ahocorasick Python extension module (easy_install ahocorasick). I isolated the problem to a trivial example: import ahocorasick t = ahocorasick.KeywordTree() t.add("a") When I run it in gdb, all is fine, same happens when I enter these instructions into Python CLI. However, when I try to...

RestrictedPython on Google AppEngine (GAE)

conditionally including queries in an advanced query in zope
I'm building a quite thorough searching mechanism for a zope site. There are lots of different ways of searching, and because it might want to search for multiple values on the same index (and match all of them) I need to do it using AdvanceQuery. I've built my queries like this: if self.text(): text_query = And() for t in self....
