@title{Handin-Server and Client}
|
|
|
|
The @filepath{handin-server} collection directory contains a server to
|
|
be run by a course instructor for accepting homework assignments and
|
|
reporting on submitted assignments.
|
|
|
|
The @filepath{handin-client} collection directory contains a client to be
|
|
customized then re-distributed to students in the course. The
|
|
customized client will embed a particular hostname and port where the
|
|
server is running, as well as a server certificate.
|
|
|
|
With a customized client, students simply install a @filepath{.plt}
|
|
file---so there's no futzing with configuration dialogs and
|
|
certificates. A student can install any number of clients at once
|
|
(assuming that the clients are properly customized, as described
|
|
below).
|
|
|
|
The result, on the student's side, is a @onscreen{Handin} button in
|
|
DrRacket's toolbar. Clicking the @onscreen{Handin} button allows the
|
|
student to type a password and upload the current content of the
|
|
definitions and interactions window to the course instructor's server.
|
|
The @onscreen{File} menu is also extended with a @onscreen{Manage...}
|
|
menu item for managing a handin account (i.e., changing the password
|
|
and other information, or creating a new account if the instructor
|
|
configures the server to allow new accounts). Students can submit
|
|
joint work by submitting with a concatenation of usernames separated
|
|
by a ``@tt{+}''.
|
|
|
|
On the instructor's side, the handin server can be configured to check
|
|
the student's submission before accepting it.
|
|
|
|
The handin process uses SSL, so it is effectively as secure as the
|
|
server and each user's password.
