Regex matching very slow
I am trying to parse a PDF to extract the text from it (please don't suggest any libraries to do this, as this is part of learning the format).

Optimising RSS parsing on App Engine to avoid high CPU warnings
I'm pulling some RSS feeds into a datastore in App Engine to serve up to an iPhone app. I use cron to schedule updating the RSS every x minutes. Each task only parses one RSS feed (which has 15-20 items). I frequently get warnings about high CPU usage in the App Engine dashboard, so I'm looking for ways to optimise my code. Currently, I...
Web-based game in Python + Django and client browser polling
I am creating a text-based game that implements a basic model in which multiple (10+) players interact with data and one moderator watches them and sets certain environmental statistics that affect gameplay.

Better use a tuple or numpy array for storing coordinates
Hi, I'm porting an C++ scientific application to python, and as I'm new to python, some problems come to my mind: 1) I'm defining a class that will contain the coordinates (x,y). These values will be accessed several times, but they only will be read after the class instantiation. Is it better to use an tuple or an numpy array, both in...

Python urlparse, correct or incorrect?
Python's urlparse function parses an url into six components (scheme, netloc, path and others stuff) Now I've found that parsing "example.com/path/file.ext" return no netloc but a path "example.com/path/file.ext". Should't it be netloc = "example.com" and path = "/path/file.ext"? Do we really need a "://" to determine wether or not a ...

I currently have a SQL database of passwords stored in MD5. The server needs to generate a unique key, then sends to the client. In the client, it will use the key as a salt then hash together with the password and send back to the server. The only problem is that the the SQL DB has the passwords in MD5 already.
