Go to the command line. YES!

Get to your home directory.

$ cd

Check if you have a public_html directory

$ ls public_html

If you don't, create one

$ mkdir public_html

Make sure your home directory would allow access to public_html

$ chmod 711 ~

Make sure your public_html allows access to your web pages

$ chmod 711 public_html

Copy your .pde file into your public_html directory

$ cp Processing/Sketchbook/XXXX.pde public_html

Make sure you pde file is accessible.
See if your browswer can load http://www.cs.unca.edu/~yourid/XXXX.pde

Connect to you public_html directory

$ cd public_html

Using your favorite text editor (or pico), create a file
call XXXX.html that contains the following two lines:

<script src="processing.js"></script> 
<canvas data-processing-sources="XXXX.pde"></canvas>

You must have a copy of processing.js in your directory.
Normally, you would download the latest copy off the internet
(from http://processingjs.org/download/). And you can do that.
However, to avoid having 30 copies of processing.js,
try creating a "hard link" to my copy of processing.js.

$ ln ~brock/public_html/processing.js .

Now see if your browswer can load http://www.cs.unca.edu/~yourid/XXXX.html
