Python simple web server

The absolutely fastest way to get a simple web server up and running using Python 3, for development purposes.

cd my_web_root

Or if you are on Python 2.x:

cd my_web_root
python -m SimpleHTTPServer 8000

Then just access http://your-ip:8000 to access the web server contents. Hit ctrl+c to exit.

Installing PySide into a virtualenv

I’ve been struggling to install a portable/relocatable virtualenv with PySide 1.2.2 for Python 2.7. On Windows, this works out of the box but it’s more difficult on Linux and OS X, although I came up with a patch for OS X. This guide will not go into detail on portability/relocatability and will merely touch upon how to get started with PySide in a virtualenv. It looks like PySide 1.2.3 will have substantial changes which will allow for easier portability/relocatability and I will make a post on that as soon as it is generally available.
