Quake III Arena Cell Shading 1.0
Quake III Arena Cell Shadings goal is to add Cell Shading capabilities to the Quake III engine with Real-time performance. more>>
Quake III Arena Cell Shadings goal is to add Cell Shading capabilities to the Quake III engine with Real-time performance.
In order to provide such feature we have decided to use Kuwahara filter. Kuwahara filter is a noise-reduction filter that preserves edges.
It uses four subquadrants to calculate the mean and variance and chooses the mean value for the region with the smallest variance.
To increase the hand-painted effect we have decided to apply a simple blur filter to reduce hard-edges on textures and increase the flatness effect.
To produce the cell shading edege effect we use no gfx card shaders, so our implementation could run with almost any gfx card. This effect is produced by painting backface polygons with a thick wireframe without textures and repaint all the scene, but this time, with textures.
To test our modified engine just place our binary in your games folder to frag all day long!
Ensure you have a copy of Quake 3 Arena installed on your PC. Youre going to need the artwork/content from the game because it is not redistributable.

Solar Visitor 0.2.1
Solar Visitor is a space simulator where the user flies around our Solar System in a 3D view. more>>
Solar Visitor is a space simulator where the user flies around our Solar System in a 3D view. The program and source code are offered free, there are builds for Windows and Linux. Solar Visitor uses the Ogre graphics library. The planets and objects were created with the Blender program.
Because Solar Visitor is a 3D program, performance depends on the capabilities of the users video system.
If you wish you may build from source using available tools but be warned this is not an easy task. An addition to Ogre a compiler and IDE (on Windows) are required. The Ogre web site has installation instructions for its use. Those without c/c++ experience will find themselves jumping in the deep end.
With the release of version 0.2.x the user can view planets rendered from textures which is a vast improvement over the painted colours of 0.1.0. There is still realism to add. For instance, the orbits are engineered to showcase shadow effects and not be realistic, where eclipses are rare.
The program code is released under the GPL, the media are generated from downloadable images on the web, details of location are provided. Images remain the property of respective owners.
Enhancements:
- bugfixes
- tilted orbits

A Small MUD 1.3
A Small MUD is a minimal MUD implementation. more>>
A Small MUD project is a minimal MUD implementation.
A Small MUD is a minimal MUD implementation, with some mildly intelligent mobs running around creating rooms.
A few pointers when reading the source code... the World class contains the "cells" in the dungeon - all those are created randomly by the mobs.
The MobFactory class contains and controls all mobs in the world - the class holds a reference to the World class.
Cells are specified by the World::CELL struct and mobs by the MobFactory::MOB struct. The SmallHandler class contains the World, MobFactory, and active sockets list (via SocketHandler).
Finally, the SmallSocket class handles all socket communication and the ListenSocket template class acts as the socket listen server.

cpufrequtils 002
cpufrequtils project consists of a library which offers an unified access method for userspace tools. more>>
cpufrequtils project consists of a library which offers an unified access method for userspace tools and programs to the CPU frequency and voltage scaling (cpufreq) subsystem in the Linux kernel, the "cpufreq-info" and "cpufreq-set" tools to determine and set cpufreq settings, and debug tools helpful if frequency scaling doesnt work as expected.
"libcpufreq" is a library which offers a unified access method for userspace tools and programs to the cpufreq core and drivers in the Linux kernel.
This allows for code reduction in userspace tools, a clean implementation of the interaction to the cpufreq core, and support for both the sysfs and proc interfaces [depending on configuration, see below].
"cpufreq-info" determines current cpufreq settings, and provides useful
debug information to users and bug-hunters.
"cpufreq-set" allows to set a specific frequency and/or new cpufreq policies
without having to type "/sys/devices/system/cpu/cpu0/cpufreq" all the time.
Installation:
./configure && make
su
make install
should suffice on most systems. It builds default libcpufreq, cpufreq-set and cpufreq-info files and installs them in /usr/local/lib and /usr/local/bin, respectively. Due to the autotoolization by Mattia Dongili the standard options to make and make install, like "--prefix=/usr", can be passed and (should) work correctly.
Options and dependencies:
./configure by default enables the sysfs interface, but disables the
deprecated /proc interface to the cpufreq core in the Linux kernel. For the sysfs interface to build and work correctly, you need "libsysfs", which is part of the "sysfsutils" package. Current requirement is sysfsutils-1.0.0 or later.
To disable the sysfs interface, pass the option "--disable-sysfs" to ./configure.
To enable the (deprecated) /proc interface support, pass the option "--enable-proc" to ./configure.
Enhancements:
- This release includes a couple of build and Makefile fixes and also a patch which causes cpufrequtils to always set the maximum frequency before the minimum frequency on a policy change, as the kernel expects.

IP Accounter 1.31
IPAC-NG is the iptables/ipchains based IP accounting package for Linux. more>>
IPAC-NG is the iptables/ipchains based IP accounting package for Linux.
It collects, summarizes, and nicely displays IP accounting data. Its output can be a simple ASCII table, or graph images. Ipchains and iptables are supported. Logs are stored in files, gdbm, or PostgreSQL database.
ipac consists of one perl script and one C program:
- fetchipac, executed from cron once in a while, reads the current ip accounting data assembled by the kernel and stores it into a database
- ipacsum summarizes the data from a set of records from the database and, optionally,
replaces these records by one. It displays the values as a simple table containing the sums, as png graph pictures or as ascii graph pictures.

Openwall tcb suite 1.0
Openwall tcb suite package contains core components of our tcb suite implementing the alternative password shadowing scheme. more>>
Openwall tcb suite package contains core components of our tcb suite implementing the alternative password shadowing scheme on Owl.
It is being made available separately from Owl primarily for use by other distributions. Note that you need to have the password hashing framework introduced with crypt_blowfish patched into glibc to compile and use this.
The package consists of three components: pam_tcb, libnss_tcb, and libtcb.
pam_tcb is a PAM module which supersedes pam_unix. It also implements the tcb password shadowing scheme.
The tcb scheme allows many core system utilities (passwd(1) being the primary example) to operate with little privilege. libnss_tcb is the accompanying NSS module. libtcb contains code shared by the PAM and NSS modules and is also used by user management tools on Owl due to our shadow suite patches.

AFS::Cell 2.4.0
AFS::Cell is a Perl module to administer AFS Cells. more>>
SYNOPSIS
use AFS::Cell qw (configdir expandcell
getcellinfo localcell
whichcell wscell
);
my $conf_dir = configdir;
my $cell = expandcell(mpa);
$cell = localcell;
$cell = whichcell(./);
$cell = wscell;
($cell, my @hosts) = getcellinfo;
print "Cell: $celln";
foreach my $host (@hosts) {
print(" $hostn");
}
NOTE: The following lines are version 1 style: all names are exported by default. This style is deprecated !!!
use AFS; # import all AFS names
use AFS @AFS::CELL; # import just the cell config names
DESCRIPTION ^
This module provides several functions to configure and to maintain an AFS cell. It is used to maintain the configuration directory. Any function required must by explicitly listed by the use statement to be exported into the calling package.
Some of these functions have the optional argument FOLLOW. FOLLOW determines which file should be used should PATH be a symbolic link. If FOLLOW be set to 1, then the symbolic link is followed to its target. If FOLLOW is set to 0, then the function applies to the symbolic link itself. If not specified FOLLOW defaults to 1.

Data::Report 0.06
Data::Report provides a framework for flexible reporting. more>>
Data::Report provides a framework for flexible reporting.
Data::Report is a flexible, plugin-driven reporting framework. It makes it easy to define reports that can be produced in text, HTML and CSV. Textual ornaments like extra empty lines, dashed lines, and cell lines can be added in a way similar to HTML style sheets.
The Data::Report framework consists of three parts:
The plugins
Plugins implement a specific type of report. Standard plugins provided are Data::Report::Plugin::Text for textual reports, Data::Report::Plugin::Html for HTML reports, and Data::Report::Plugin::Csv for CSV (comma-separated) files.
Users can, and are encouraged, to develop their own plugins to handle different styles and types of reports.
The base class
The base class Data::Report::Base implements the functionality common to all reporters, plus a number of utility functions the plugins can use.
The factory
The actual Data::Report module is a factory that creates a reporter for a given report type by selecting the appropriate plugin and returning an instance thereof.
