I have written a class that will be used to store parameters in a convenient way for pickling. It overloads __setattr__ for convenient access. It also uses a list to remember the order in which attributes where added, so that the iteration order is predictable and constant. Here it is: class Parameters(object): def __init__(self): ...
I've been considering using Google App Engine for a few hobby projects. While they won't be handling any sensitive data, I'd still like to make them relatively secure for a number of reasons, like learning about security, legal, etc. What security issues need to be addressed when working with Google App Engine? Are they the same issues...

Hi. What's the best way to handle form POST data in my Pylons app? I've tried: Having a seperate GET method and a POST method with a rest.restrict('post') decorator. Problem -- if there were validation errors then you can't redisplay the form with the data which the user entered because you have to redirect back to the GET method OR y...

I'm trying to get a reader to recover from broken XML. Using the libxml2.XML_PARSE_RECOVER option with the DOM api (libxml2.readDoc) works and it recovers from entity problems. However using the option with the reader API (which is essential due to the size of documents we are parsing) does not work. It just gets stuck in a perpetual lo...
I have a QWebView in my app which renders a html page stored in the app as a Qresource. This page, however requires meaty external Javascript libraries such as MathJax, which I would want to include as a resource due to its size. My problem is that it seems that QtWebkit does not cache these files as a regular browser would do, and eve...
Facebook returns access tokens in the form of a string: 'access_token=159565124071460|2.D98PLonBwOyYWlLMhMyNqA__.3600.1286373600-517705339|bFRH8d2SAeV-PpPUhbRkahcERfw&expires=4375' Is there a way to parse the access_token without using regex?

The cluster uses Sun GridEngine and my program is written to run using Parallel Python, numpy, scipy on Python 2.5.8.

I have been thinking of ways I could uniquely identify a computer in python. First, I thought about checking the user's mac address and hard disk space, then I tried to compute some sort of rating from many of these variables. However, this solution doesn't feel right. It takes a long time to run and I had to change it many times already...
I've noticed sometimes if you call dir() on a package/module, you'll see other modules in the namespace that were imported as part of the implementation and aren't meant for you to use. For instance, if I install the fish package from PyPI and import it, I see fish.sys, which just refers to the built-in sys module. My question is whethe...
