Mutt Address Book is a script to manage your own address book with mutt's "External Query" functionality. It features searches in fullname, e- mail address, and even comments. So you can find any person you can remember the comment to, and do not need to remember names or even cryptic aliases. It also features adding people to your address book from within mutt directly. The From or Reply-To header fields are parsed for that purpose, so you don't even have to type in the fullname or e- mail address yourself. The only thing you might type if desired is a comment for this person.
@1 Auto Delete deletes all files (in a specific directory) with dates older than the specified number of days. It can be useful if you have pages generated through user's input. It can be run manually from a browser, through telnet, or automatically using crontab. There are only two variables to edit - the directory, and the file age.
@1 Age Status Indicator for Files and Folders is a script that checks the age of files and folders, and shows "NEW" image indicators according to the age. If pointed to a folder, the script will scan through all the files in that folder for the newest file (sub-folders and files in sub-folders are omitted).
R-AddressBook is a Java address book which stores its data in XML format. It can be run on virtually any computer (including PDAs) and offers local and global address information storage, WebServices based synchronization, off- and on-line operation, no restriction on the type or number of fields for each entry, and automatic address updates.
serverizor allows you to take a normal command- based program, and run it as a tcp server in the background. This means that you can start up such programs once, and then connect to them with a command-line client, and run commands, disconnect, connect again from some other machine, etc. So, you can use it to boot up a large program such as emacs or lisp (in interpretor mode, not in editor/windowing mode) in the background, and then whenever you want to run emacs/lispy scripts, you could just run a serverizor client with a few commands. Therefore, the client and the server are the same program.
