Run Django from a VM and access it from the host

If you try to run Django development mode from a Virtual Machine and access the website from the host, you need to specify the global IP address in the "runserver" command.

For example if your VM IP address is 192.168.31.128 (in NAT mode):

You should run the server by calling (you can change the port):

python manage.py runserver 192.168.31.128:8000

Now you need to connect to the website specifying the IP address like that: http://192.168.31.128:8000.

Both from the VM:

And the Host:

The server running on Linux is much faster than the one running on Windows

Python Qt4 recipe: QSingleApplication (PySide)

Thanks to Renato Filho who helped me in this thread on the Qt Forums, I made a simple QSingleApplication class for PySide that allows you to be sure your program will be started only once.

In addition to start the application only once, we can send the arguments of the later calls of your program to the first (and only remaining) instance.

The following video summarizes the features:
