Tk::Image::Calculation is a Perl extension for graphic calculations.

SYNOPSIS

This module calculates points and lines inside or outside from simple graphic objects. At this time possible objects:
"oval",
"circle",
"polygon"

Plutimikation is a math learning game for children. It trains basic calculation skills like multiplication in the number range between 1 and 100.
Its simple, it works and my daughter likes it. Its free software written for the KDE desktop.
Enhancements:
- First public release: Plutimikation 0.1.

Tactical Operations: Crossfire is a tactical shooter based on Unreal Tournament 2004.

Tactical Operations: Crossfire is a fast paced first person online shooter in which two teams, terrorists and special forces, duke it out in a wide variety of environments with various objectives to accomplish. From rescuing hostages kept in a small desert town in Saudi-Arabia to preventing the bombing of an oil refinery on the Caspian sea shore. There are no less than fourteen official maps to choose from!

Each map is played for a certain amount of time and the team having won the most rounds when the time runs out is declared the winner. A round can be won either by completing the objective set for that team, such as rescueing the hostages, or by simply eliminating all players on the opposite team.

A large number of weapons is avaialable for both teams, which can be purchased by each player at the start of the round. Out of the thirty weapons currently available, theres bound to be a weapon to suit your style of playing, be it either up close and personal with the Benelli Nova tactical shotgun or sneaky sniper work with the Dragunov SVD.

Tactical Operations: Crossfire continues where the popular Tactical Ops: Assault on Terror left off, with many classic weapons returning and remakes of some of the original maps. To play TO:C, you will need Unreal Tournament 2004 installed and patched to the latest version (3369). Tactical Ops: Crossfire can be played on Windows, Linux and Mac systems.

Trip Tracker is a position tracking client-server system. Trip Tracker is designed to assist people in setting up a real-time tracking environment with either a private or public tracking server.
The Trip Tracker GPS client sends coordinates to the tracking server to update its position. In the event that the GPS client loses its Internet connection, it can send all collected coordinates to the tracking server as soon as its back online.
The tracking server saves all the coordinates and can forward them to listening map clients.
Version restrictions:
- The map client can only display a map of Norway, as the WMS server is hardcoded in the server-side PHP script "mapservice.php". This may change in the future. If you know any good WMS servers we might add it to the server-side script, but you still need to add the proper WMS layers in the source code to make it work.
- The GPS client version 0.8 does not set up the Java Communications library properly so it most likely wont find your GPS receiver. We hope to address this issue in the next release quite soon.
- And more...

bandwidth monitor is a small application which polls /proc/net/dev for the byte counts for a given network device , and calculates the RX and TX bandwidths. Originally a shell script, then a Perl script, now rewritten in C so that it can easily be used on embedded devices like the Linksys WRT54G as well as.

This program started as a shell script that I ran on my home-brew firewall wireless router (Linux, of course, on a 486/66) to keep track of my incoming and outgoing bandwidth. This let me know that I was getting the bandwidth that I paid for, and it also helped me keep an eye on the throttling of bulk traffic so that I didnt choke out my interactive sessions. Of course, that was before I had QOS.

The program is probably tied to Linux, since it grabs the byte counts for the requested interface right from /proc/net/dev. It could pretty easily be modified to grab the same information from the output of /sbin/ifconfig, but that would waste resources to spawn a new process to parse the /proc/net/dev file and regurgitate it to us. Also, I havent bothered to look at how uniform the output of the byte counts from /sbin/ifconfig is on other operating systems.

As a side note, the C version also uses nanosleep() and gettimeofday() to get more accurate polling intervals and track the overall time (since sleep(), usleep(), nanosleep(), et. al. only guaruntee to wait at least as long as you request, but do not guaruntee that it wont be possibly much longer...) So, if you were interested in porting it, youd have to make sure that nanosleep() and gettimeofday() were also available, or lose the resolution of the time used in bandwidth calculations.
