I have a simple Python web crawler. It uses SQLite to store its output and also to keep a queue. I want to make the crawler multi-threaded so that it can crawl several pages at a time. I figured i would make a thread and just run several instances of the class at once, so they all run concurrently. But the question is, how many should i ...

I am writing a plug-in for Trac. I would like to add an event to the time line each time the plug-in receives some data from a Git post-receive hook. Looking at the timeline API, it seems you can only add new source of events. So you are responsible for retrieving and displaying the data. I would prefer saving my event to an existent so...
A quickie, and hopefully an easy one. I'm following the docs at http://docs.djangoproject.com/en/dev/topics/auth/ to get just some simple user authentication in place. I don't have any special requirements at all, I just need to know if a user is logged in or not, that's about it. I'm using the login_required decorator, and it's working ...

I need to use easy_install to install a package. I installed the enthought distribution, and popped into IDLE to say: >>> easy_install SQLobject SyntaxError: invalid syntax What am I doing wrong? easy_install certainly exists, as does the package. help('easy_install') gives me some basic help. import easy_install doesn't change t...
I like the very simple but still really elegant look and feel of the django admin and I was wondering if there is a way to apply it to my own application. (I think that I've read something like that somewhere, but now I cannot find the page again.) (edited: what I am looking for is a way to do it automatically by extending templates, i...
