Pachyderm is a small utility that quickly checks your system clock to make sure its sane. This can help workaround the occasional problem where a machine has its clock reset to January 1, 1970 after rebooting.

To use it, simply run it. If Pachyderm thinks your system clock is screwed up, it will ask you to change or confirm it. If the system clock seems OK, Pachyderm will exit without any user action.

One good use for Pachyderm is to put it into your login items so that it runs every time you log in (and, by extension, every time you reboot).

Quantum Mechanics Utilities contain applications for an undergraduate course using either Macs or Wintel computers.

This file yields application utilities for an undergraduate course in quantum mechanics. You can use them to easily find and display energy eigenvalues and eigenfunctions for the one dimensional time independent Schroedinger equation, and for the one particle radial equation.

MacJanitor is designed to be used on a periodic basis by Mac OS X users who dont leave their computer on (and awake) 24 hours a day. MacJanitor is provided as freeware as a service to laptop and energy-conscious home users.
MacJanitor provides a way to run system maintenance tasks at the click of a button.
The Unix subsystems on Mac OS X were originally written for machines that were typically never shut off. Mac OS X inherits this assumption in version 1.x, and has many system maintenance tasks that are scheduled to run between 3 am and 5 am. In addition, there are scripts designed to run weekly on weekends, and once a month in the middle of the night.
If these maintenance tasks are never run (such as on a laptop that is always shut off at night), many log files and system database will grow extremely large or fail to get backed up.
Laptop users could click the daily button every morning (or every few days), or office workers could click the weekly button on Mondays.
If youve been leaving your machine off at night without allowing the maintenance tasks to run for several weeks or more, the first time you run them using MacJanitor may take several minutes. Also, if your log files have grown extremely large and you are low on disk space, the tasks may have problems moving the files around and compressing them. After that, it typically takes less than a minute for each task.
The output of the task is displayed in the scrolling view in the bottom part of the window. If for some reason you feel the need, you may print the output of the system maintenance tasks (but why?...).
Enhancements:
- Built for Panther and higher (Tiger compatible).
- Uses the periodic tool instead of running the tasks directly.

Unhide utilities is a set of 2 applications for changing the visibility of files and folders.

Unhide Desktop Folder
This tool allows you to make the Desktop Folder visible in the network again if youve installed OS 9.1 or 9.2, which has made it invisible on the network. Just drop your volumes onto this tool and their Desktop Folders will re-appear when seen as mounted AppleShare volumes.

Additional feature: You can also have the folder renamed so that it appears like any other folder in the root dir of your hard disk. The items will then, of course, disappear from your desktop area, but you can always move them back there again (for this feature, hold down the Option key when dropping a volume onto this tool).

Change File Visibility
This tool allows you to make any hidden file or folder visible, or hide them again. This is very handy to get rid of all the OS X files and folders that come pre-installed on your Macs nowadays: Simple drop your hard disk icon onto this tool, and you will see all items on the root of your disk. Change the checkboxes for all hideen items such as dev, bin, etc to make them visible, then use the Finder to move them all to the Trash.
