I tried a couple things that seemed reasonable: FILT...
Hi, I am writing a system of comments in DJango and I want to authenticate my users with OpenID. I see a lot of solutions that integrate DJango and OpenID, but all of these consist on a login form. I don't want to provide a login form to my users (in fact, i don't want to have a users table). In my comment form there is a URL field. ...

Hello, I'm trying to get into Python and, more specifically, Zope and Plone. I read the book Professional Plone Development and one thing it says is that one MUST use version control. But the book did not expand on that topic any further. This leads to two questions. First: SVN or git? (My research points to git, if only to learn it. I'...

I need a wxPython preference dialog box from a Python application. I could hand-code it (and use wxGlade to do part of the job), but I was wondering if there is no tool that makes creation of simple preference dialog boxes easier. The 'easier' part would be in that you can specify that you need e.g. a text box, and both the GUI elements...
