Homework Hints

This page is for you guys to edit, to provide any homework hints that you think may be helpful. As a reminder, everyone is encouraged to discuss the homeworks, but actually writing the code together, or sharing code between each other, is not allowed. So, you may want to mention particular useful functions, good commands, or handy links, but please do not post code, other than a line or two.

Remember to dot your i's, cross your t's and close your files and sockets smile

For svn commands, the one's Proffesor gave work just fine. Remember svn update, so you can turn in new versions of your homework.
