Sphinx PDF output is bad. How do I chase down the cause? | 37,615,276 | 0 | 0 | 1,143 | 0 | pdf,python-sphinx,rst2pdf | We had a similar problem: bad pdf output on project with a lot of chapters and images.

Django virtual environment | 25,851,210 | 4 | 1 | 149 | 0 | django,python-2.7,virtualenv | It doesn't matter where the directory is - the only important thing is that you activate the virtual environment every time you want to work on the project.
I personally prefer to have the project directory inside the virtual env directory, but that is not required.
One caveat: don't put the virtual env inside your pro... | 0 | 0 | 0 | 0 | 2014-09-15T15:05:00.000 | 1 | 1.2 | true | 25,851,142 | 1 | 0 | 1 | 1 | What is the proper way of adding an already existing Django project to a newly created virtual environment?

Quickfix failing to read repeating group | 25,858,986 | 5 | 1 | 1,635 | 0 | python,quickfix,fix-protocol | (edit -- I have turned off the data dictionary in the config file -- could it have anything to do with that?)
Yep, that's exactly the problem.
Without the DD, your engine doesn't know when a repeating group ends or begins. As far as it's concerned, there's no such thing as repeating groups.
You need a DD, and you nee... | 0 | 0 | 0 | 0 | 2014-09-15T22:52:00.000 | 2 | 1.2 | true | 25,858,091 | 0 | 0 | 1 | 2 | I am using quickfix in Windows with python bindings.

Quickfix failing to read repeating group | 49,272,369 | 1 | 1 | 1,635 | 0 | python,quickfix,fix-protocol | I realize this thread is years old but I had this exact problem and finally resolved it so I am putting it here to help anyone else that stumbles across this.
The issue was that in my config I was using the 'DataDictionary=..' parameter. Changing this to 'AppDataDictionary=...' solved my problem.

Can Apache be used as a front end for Django and Tornado at the same time? | 25,861,972 | 1 | 0 | 534 | 0 | python,django,apache,tornado,wsgi | You would be better off to use nginx as a front end proxy on port 80 and have it proxy to both Apache/mod_wsgi and Tornado as backends on their own ports.
