Here's the paper: http://www.cs.auckland.ac.nz/~pgut001/pubs/secure_del.html

This includes the list of patterns to use (22 of them) to overwrite data.

I don't know where ther are sources, sorry.

Conceptually, it doesn't seem that difficult:

1) Open a file
2) Go to beginning of file
3) Write the pattern over and over until the end of the file is reached
4) Repeat steps 2 and 3 for all the patterns
5) Close the file

For memory, it's even easier because there is no file management, you just iterate over the memory buffer, writing all the patterns in succession.
