Building an Internet Router
We strongly encourage you to use a version control system to manage your files. Version control systems keep track of the changes you make to a project over time. This allows you to retrieve older versions of files and identify why you changed files in a particular way.
Version-control repositories can be set up at google's hosting service and at the student-run computing facility, (as well as in your computer lab home directory, etc.) Do note that Google's facility is world-readable and you need to take on board the implications of this.
We would observe that hardware may fail at ANY time, but usually it fails within 24 hours of submission.
