  • xmeltdown

    A program to melt your screen

  • I was in college in the mid 1990's. Our school had hundreds of Unix workstations from Sun, HP, DEC, IBM, and SGI. Everything was tied together with MIT's Project Athena which used the AFS Andrew File System, Kerberos, and the Zephyr instant messaging system.

    Your home dir would be mounted as /school/login

    The directory paths would be really long like /afs/school/math/maple/maple5.3 so there were 2 commands named add and attach to mount dirs to /school

    add maple5.3 and you would have /school/maple5.3 and it would source .environment script in that dir to set up the tool and it /school/maple5.3/bin to your PATH

    The attach command did the same thing but did NOT source the .environment file

    If you needed to access another student's dir it was explicitly written in the intro computing class book to use attach and not add

    I had a lot of scripts and utilities that friends would use. They told other random people that I didn't know.

    So of course I made a file that would be updated any time I logged in showing my current machine name. Then I made a .environment file that would xhost + my_machine and send me a Zephyr message saying "I just added and xhosted your machine"

    I would wait a few minutes and then run xflip and xmeltdown and set the -display to their machine. If they were in the same computer lab as me I would see them start to freak out. These programs basically froze your display for a few seconds while inverting the screen or causing everything to appear to melt to the bottom.

    No real harm but it was pretty funny when I was 19
