Fl_TeacherTool: Award-winning Software With an Uncertain Future

"Fl_TeacherTool uses pre-existing applications as the basis for many of its features, including VNC Reflector, VNC Snapshot, RealVNC, ImageMagick, and gThumb. In this sense, Fl_TeacherTool is partly a control center -- designed mainly for teachers, but useful for anyone managing a thin client system, such as a manager of an Internet café who might want to monitor users' activities or interact with them.

"The main window of Fl_TeacherTool is a list of clients that are logged in, with function buttons arrayed to the left. The list also displays the amount of memory that each client is using, as well as how long each user has been logged in. These features are important because memory usage is often an issue on thin client systems. Clients that are suddenly using more memory than anyone else may be doing something that they shouldn't, such as watching a video. Similarly, in a public or semi-public setting, a user logged in for a long period may have forgotten to log off, tying up resources that other users might need. Administrators must refresh the list from time to time, since it is not updated automatically with new logins."
