AWK address collection is a collection of scripts to extract information from a loosely formatted address file. It currently allows you to lookup addresses and phone numbers, list category members, list birthdates and ICQ UINs, automatically create a ~/.micqrc file with all ICQ users, and ~/diary with birthday reminders from the address database. It can be extended very easily.
Scsh is a systems-programming environment for POSIX systems and Win32, embedded in the Scheme programming language. It includes a high-level process notation for writing shell-script like programs, with pipelines and redirections. Scsh additionally provides low-level access to POSIX primitives, plus important non-POSIX extensions such as sockets. Scsh is implemented on top of Scheme48, a portable bytecode implementation of Scheme. A number of user-contributed extensions are available, including an extensible HTTP and FTP server, a socket-level PostgreSQL interface, a programmable text formatting language, and a Postscript generation language.
charities.cron is a cron script in the gawk language to frequent the various charity sites affiliated with thehungersite.com and freedonation.com. These sites enable Web users to donate food, health care, and other goods simply by clicking on a link. The sites generally count one click per IP address per day; by making this a daily cron job, you can cause thousands of dollars to be donated to charity each year.
Shmplayer executes a single instance of mplayer in the background and controls it through a FIFO. It supports many of the features you'll find in XMMS and it is easily extendible. However, unlike XMMS, shmplayer doesn't require an X server to be active. You can even use it from a remote shell. Shmplayer has also some unique features like "jgrep" that lets you jump to the first "grepped" match of the playlist.
