Free grey software for linux

Grey Matter is a CGI-based logging application suitable for a variety of purposes, mainly blogging. The project doesnt require a backend database and features a very flexible template system, as well as a karma and comment system.
Enhancements:
- Continuing code refactoring, with small admin UI enhancements such as paging on very long screens.
- Contains security enhancements and bugfixes as well.

Gray is a GNOME theme, and its the gray version of the nice theme "Mint" by lokheed, with a new Metacity theme!

Gray-Flat has got different menubar and different metacity (obviusly you can use Gray-Flat with Gray metacity theme!).

Stavrosg made a port of the metacity for Xfwm4! Enjoy his work!

Gray-Xfwm4 is the Gray theme ported to Xfwm4.

Original theme by cimi86
Adopted for xfwm4 by Stavros Giannouris (stavrosg)

wxSpellcast project is a portable rewrite of the classic X11 multiplayer game.
wxSpellcast is a modern version of Andrew Plotkins classic X11 "spellcast" game. It features client-server networking and a GTK+ GUI on Unix, thanks to the wxWindows cross-platform development library.
Enhancements:
- Fixed a bug that would cause all players to be referred to as "it" instead of the appropriate gender sometimes.
- Fixed the "grey background" cosmetic problem on Windows.
- Updated the Windows binary to use wxWindows 2.4.0.

Color::Object is a OO-Color Module.

A module for manipulation Colors within RGB, HSV and HSL color-spaces for usage within PDF-Documents especially with the Text::PDF::API modules.

SYNOPSIS

use Color::Object;

$cl = Color::Object->new;
$cl = Color::Object->newRGB($r,$g,$b);
$cl = Color::Object->newHSV($h,$s,$v);
$cl = Color::Object->newHSL($h,$s,$l);

$cl->setRGB($r,$g,$b);
$cl->addBrightness($br);
($h,$s,$l) = $cl->asHSL;

smf-grey is a Sendmail milter that implements the GreyList Anti SPAM technology.
This technology can significantly reduce the amount of SPAM and viruses going from zombie computers (infected Windows PC), which produce more than 80% of SPAM.
GreyList Sendmail milter has a very effective GreyList algorithm on the base of the tuple: sender IP address (C class subnet), sender envelope and recipient envelope.
Its very recommended to use the smf-grey milter combined with the smf-zombie and the smf-spf milters. Its a triple impact on SPAM and viruses, that will seriously increase the efficiency of filtration.
This milter aims to be lightweight, reliable and simple. Its written in C.
Main features:
- It has a hosts/networks whitelist;
- It has an autowhitelist;
- It can add the information header with GreyList results to scanned messages;
- It can log all milter activities through the syslog service.
Advantages:
- Small code;
- Fast work;
- Stability (production quality);
- Few system resources are required.
Enhancements:
- Whitelists auto reloading was implemented.
- Autowhitelisted records regular dumping and reloading was implemented.
- The default greylisting time period was increased.
- New TODO tasks were added.
- Cosmetic enhancements were made.

Coherent Mail Gateway is intended to be a very easy to set up MTA using SMTP and POP3. Greylisting is used on the SMTP daemon to reduce spam.

In addition, quite a lot of checks on the validity of information from the SMTP client (such as claimed server name and sender) are carried out, and anyone caught telling lies is disconnected.

Grey-, black-, and white-listing are supported, as well as (optionally) ClamAV and Spamhaus. The target market is users with static IP addresses. Others can use the system, but its value will be limited to outgoing email.
