Whatmask is a small C program that helps with network settings. Notations supported are CIDR (e.g. /24), Netmask (e.g. 255.255.255.0), and Wilcard Bits (e.g. 0.0.0.255). These notations are all identical. CIDR notation commonly has a "/" in front of the number (representing the number of bits). Whatmask can accept these notations with or without a slash. It can take any IP in the subnet along with the netmask in any format, and it will echo back the netmask in three formats, the network address, the broadcast address, the number of useable IPs, and the range of IPs in the subnet. Binaries for Linux, Win32, and MacOS 9/X are available.
Spinner is useful for keeping telnet and ssh links from dropping due to inactivity. Many firewalls and some ISPs drop connections when they are perceived as idle. By having spinner running, the server is constantly sent a tiny amount of data over the link, preserving the connection. Spinner thus acts as a keep-alive. It displays a little "spinning" ASCII character in the top left corner of your terminal. It supports any terminal capable of handling VT100-style escape codes. Spinner can also function transparently by only sending null characters to the terminal. In this mode Spinner supports any terminal. It also has a mode called "Ghost in the Machine" in which you can use Spinner to write the spinner character to any TTY, not just your own.
The Aardvark Shell Utils is a collection of three utilities designed to aid the user when working with shell scripts or from the command line. All three accept input on the command line or from standard input, and thus they can be piped with other commands. All commands come with their own man page. Included are realpath, filebase, and fileext.
How about making an apache module that converts all
images to ASCII art for viweing in lynx, etc... ?
This would be a very cool module indeed. It could be
configured to only server up the ASCI art to browsers that
could use it (or in the ALT tage text).

That's a great idea. Look for it in a future release!
