My Thesis

Stefano Grassi's Thesis

The objective of my thesis has been the realization of an application for X Window which allowed:

Programs sharing beteeen remote users linked in LAN or WAN.

Actions Recording done in these programs, with the possibility of replay automatically them later; it's useful for short demo or lessons.

Textual annotations to describe the actions done.

I graduated with 106/110.

X Sharing and Recording System

XShare is a new program for X Window for sharing applications and recording actions. You don't need any special hardware or software, only the standard X11R5 or X11R6 distribution.

What can I do with XShare ?
You can share applications between remote users: there is a sender who runs XShare and then from it he recalls other applications, and there are receivers who see the same sender's windows on their displays. Sender can leave the control of these programs to the receivers, and the remote users can use them as the applications are running on their hosts.

XShare can record the actions (the events in X11) done by the sender in an application, and play them successively. During the recording the sender can write notes about his actions, and during the playing a window with them will appear on the displays.

This is useful for teleteaching on software, and to create little demo or lessons.

What I need to run XShare ?
You don't need any special software or hardware to run XShare, because:

It becomes part of the communication between X server and X clients (user applications) in a trasparent way.
It's written in C, with the X Intrinsics Toolkit and Athena widget, so XShare interface is very simple but the code is portable on every platform with X. The interface is similar to an audio recorder.
XShare has to run only on the sender host.

Which platforms XShare supports ?
XShare was developed on Linux and AIX, but it's portable on every X Window System.

XShare realized by Stefano Grassi, at the University of Milan, Italy, 1994/95.
