Assuming trunk is what you actually want, I would guess that your

would even outperform the latter with ext3 or reiserfs by a small
margin.
Sadly, that's not the case with filesystems like FreeBSD ufs2 (at least
in sixth branch), so it's better to play safe and create subdirs if
refix at the beginning of every line?
I'd log exception name and timestamp (or id) only, pushing the full

You might want to insert return or avoid (possibly endless) recursion
altogether - just wrap it into while loop with some counter (aka
max_tries).
Also, you can get rid of code duplication by catching some basic
urllib2 exception, then checking if it's ur
mming language. Be prepared to share!
We may have another presentation in our Standard Library series as
well or just something random. Let me know if you think you'll be

PyOpenGL has a BSD-style license, that's about as 'free' as one can get
in the freeware sense.

I have a sample up here:

The higher levels in OpenGLContext support compositing multiple
transformations in a containment hierarchy for a scenegraph. See e.g.
OpenGLContext/scenegraph/transform and OpenGLContext/scenegraph/nodepath
module for that high

straightforward.
Anyway, just a vote that's trying very hard to keep on-topic for the

Again, you don't really have a cursor with a dictionary (and since it's
randomly ordered, a cursor wouldn't mean anything). A *btree* has an
order, but not a dictionary. You
