Recommended hosting

Hi all, I'd like to build a web site for myself, essentially a "vanity" web site to show off whatever web development skills I have, and perhaps do some blogging. I'm a Python developer, so I'd like to develop the site with the following stack: web applications written with Python and Flask, r

Dieter, Thanks for the response, and you're correct, debugging memory leaks is tough! So far I haven't had much luck other than determining I have a leak. I've used objgraph to see that objects are being created that don't seem to get cleaned up. What I can't figure out so far is why, they are

Debugging memory leaks

Hi all, I've written a program using Twisted that uses SqlAlchemy to access a database using threads.deferToThread(...) and SqlAlchemy's scoped_session(...). This program runs for a long time, but leaks memory slowly to the point of needing to be restarted. I don't know that the SqlAlchemy/thre

Extract images from PDF files

Hi all, I've looked around with Google quite a bit, but haven't found anything like what I'm looking for. Is there a Python library that will extract images from PDF files? My ultimate goal is to pull the images out, use the PIL library to reduce the size of the images and rebuild another PDF file

Vinay, Thanks for the quick response, very much appreciated. I tried the two scripts you pointed to, modifying the client so it produces log messages in an endless loop, and it worked fine. If I left the client running and stopped and started the server, the client would reconnect and messages wou

Guys, Thanks for your replies, they are helpful. I should have included in my initial question that I don't have as much control over the program that writes (pgm-W) as I'd like. Otherwise, the write to a different filename and then rename solution would work great. There's no way to tell from the

Determining when a file has finished copying

IPython doesn't always comes up NoColor

Vinay, Thanks for your reply, very interesting. We're currently running Python2.3 (though we are getting ready to move to Python2.5), so I'm guessing the code you're showing comes from Python2.5? I'm wondering if I can edit the handlers.py code in my Python2.3 installation, make the changes you sh
