Note on security warnings:

When viewing the home page / syllabus for CS155 using the Classes server, your browser will automatically jump to this webpage for the course on the Zoo. Because this page resides on a different server, your browser may warn you that the page you are trying to view has both "secure and nonsecure items." You should respond "Yes" to displaying nonsecure items. Trust us, the CS155 page does not contain malicious code. But we don't use the Classes server to host the entire website, so be prepared to see this warning.
