rl is a command-line tool that reads lines from an input file or stdin, randomizes the lines and outputs a specified number of lines. It does this with only a single pass over the input while trying to use as little memory as possible.

xidle uses the XScreenSaver(3) extension to receive inactivity events when a timeout is specified, running a specific program after the elapsed time. xidle also monitors the very corner of the given position for pointer activity and runs a program if the pointer sits there for more than the specified number of seconds. This behavior is always present, whether -timeout is specified or not.

The Tcl extension module gives access to the Tcl library with functionality and interface similar to the C functions of Tcl. In other words, you can: - Create Tcl interpreters The Tcl interpreters so created are Perl objects whose destructors delete the interpreters cleanly when appropriate. - Execute Tcl code in an interpreter The code can come from strings, files or Perl filehandles. - Bind in new Tcl procedures The new procedures can be either C code (with addresses presumably obtained using dl_open and dl_find_symbol) or Perl subroutines (by name, reference or as anonymous subs). The (optional) deleteProc callback in the latter case is another perl subroutine which is called when the command is explicitly deleted by name or else when the destructor for the interpreter object is explicitly or implicitly called. - Manipulate the result field of a Tcl interpreter - Set and get values of variables in a Tcl interpreter - Tie perl variables to variables in a Tcl interpreter The variables can be either scalars or hashes.

XBellD is a small daemon for replacing the standard X Window System terminal bell with a more interesting set of sounds. This is useful for systems where the terminal bell is handled by the "PC Speaker," or where different sounds are desired for different classes of X clients. XBellD works by intercepting terminal bell requests on the server side, and then playing user-specified sounds through a PCM capable soundcard. The resource class of the client making a terminal bell request is used to match a corresponding sound file which should be played when such a request is made.

ACM is a LAN-oriented, multiplayer aerial combat simulation. My main design objective was to provide source code that could be easily compiled and executed on a wide variety of platforms. To that end, acm is written entirely in C, exploiting the programming features of Unix, X11, and the BSD socket interface. Players engage in air to air combat against one another using heat seeking missiles and cannons. ACM is implemented as two programs. The first, named "acm", is a small program that, when invoked, starts a flight session on a given workstation. The second component, named "acms", is a server process that manages the multiplayer environment. It also manages the flight simulation and display management that is required. Most players will prefer to run the acms process on a back-end server system on their local area network. Players at client workstations can then invoke the acm program to begin play.

p5-MatrixReal is port of the perl module Math::MatrixReal, implementing a matrix of Reals. Math::MatrixReal needs support for operator overloading to support operations on matrixes as though they were just another basic perl type. In addition to the basics (+, -, *) also supported are: matrix norm, matrix transposition, matrix inverse, determinant of a matrix, order and numerical condition of a matrix, scalar product of vectors, vector product of vectors, vector length, projection of row and column vectors, a comfortable way for reading in a matrix from a file, the keyboard or your code, solving linear equations, etc. It also has an implementation of Kleene's algorithm for finding minimal costs for paths in a graph.
