The 24-Hour Professor

This is one of the reasons I burned out on full-time teaching. At first it’s great because you’re making yourself more accessible, and that’s a good thing, right? Suddenly students are sending you IMs at midnight. They’re expecting responses via e-mail within two or three hours. On weekends.

Running this example requires no less than 6 processes to be running, 4 of which require commands spanning multiple lines to start.

You can see the fruits of my labor, a shell script that starts everything running. For everyday use, I’ve broken it into 5 different shell scripts:,,,, and one for the application (e.g., or

I haven’t even started writing my own programs, this is just to run the example. Folks, developers are going to be slow to adopt Jini until this get easier.
