If I could count the number of times I wanted to share something on my computer with someone else in my home or office, it would be a big number.
Quite freququently, it wasn't worth the trouble of using e-mail, scp, or a USB drive, and definitely not worth pushing to an actual site so that anyone can see it. Or it was easier to just have them come look at my screen.
Well, once again, Python to the rescue! Python has a SimpleHTTPServer module which can be used from the command line:
cd /path/to/your/stuff python -m SimpleHTTPServer
As easy as that, you're now running a Web server on your local IP address. The default is port 8000. If you want to run at a specific port, just add the port number to the command line:
python -m SimpleHTTPServer 5555
Now you can share static content with anyone on your network on a whim.
