Free grey software for linux

Scam-grey is a milter which filters mail originating from MS Windows hosts. Scam-grey filter provides you the ability to mitigate the flow of unwanted email from such hosts using grey listing.

How it works:
On the first delivery attempt from a Windows host, Scam-grey generates a temporary error message. Subsequent delivery attempts made after the delay period will be allowed through. Unlike standard mail servers, virus, trojan infected hosts and zombies are not designed to retry the delivery after a temporary failure.

Scam-grey pairs

the helo string
the IP address of the sending server (host)
as a record and returns a temporary failure (SMTP code 450 extended code 4.7.1) if the host is greylisted.

The record is expired if there is no connection for the matching record within the next 24 hours. Click here to see a sample of mail servers which are currently greylisted

SQLgrey is a Postfix greylisting policy service with auto- whitelisting and an SQL database as storage backend.

Main features:
- SQLgrey can withstand a database crash (grey-listing is automatically switched off)
- 3 grey-listing algorithms to choose from
- Support for file-based IP and FQDN whitelists
- Support for fetching up-to-date whitelists from a repository
- Can mail the admin when the database is unavailable
- Auto-whitelists now understand SRS (SPF-aware mail forwarding)
- IPv6 support
- OPTIN / OPTOUT support
- Fine log controls
- Activity reports

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)

FreeType 2 is a software font engine that is designed to be small, efficient, highly customizable and portable while capable of producing high-quality output (glyph images). FreeType 2 project can be used in graphics libraries, display servers, font conversion tools, text image generation tools, and many other products as well.
Note that FreeType 2 is a font service and doesnt provide APIs to perform higher-level features, like text layout or graphics processing (e.g. colored text rendering, "hollowing", etc..).
However, it greatly simplifies these tasks by providing a simple, easy to use and uniform interface to access the content of font files.
FreeType 2 is released under two open-source licenses: our own BSD-like FreeType License and the GPL. It can thus be used by any kind of projects, be they proprietary or not.
Main features:
- FreeType 2 provides a simple and easy-to-use API to access font content in a uniform way, independently of the file format. Additionally, some format-specific APIs can be used to access special data in the font file.
- Unlike most comparable libraries, FreeType 2 supports scalable font formats like TrueType or Type 1 natively and can return the outline data (and control instructions/hints) to client applications.
- The design of FreeType 2 is based on modules that can be either linked statically to the library at compile time, or loaded on demand at runtime. Modules are used to support specific font formats, or even new glyph image formats !
- FreeType 2 was written with embedded systems in mind. This means that it doesnt use static writable data (i.e. it can be run from ROM directly), that client applications can provide their own memory manager and i/o stream implementation.
- The latter allows you to easily read from ROM-based, compressed or remote font files with the same API. Several stream implementations can be used concurrently with a single FreeType 2 instance.
- You can also reduce the size of the FreeType 2 code by only compiling the modules you need for your embedded project/environment.
- By default, FreeType 2 supports the following font formats:
- TrueType fonts (and collections)
- Type 1 fonts
- CID-keyed Type 1 fonts
- CFF fonts
- OpenType fonts (both TrueType and CFF variants)
- SFNT-based bitmap fonts
- X11 PCF fonts
- Windows FNT fonts
- BDF fonts (including anti-aliased ones)
- PFR fonts
- Type42 fonts (limited support)
- From a given glyph outline, FreeType 2 is capable of producing a high-quality monochrome bitmap, or anti-aliased pixmap, using 256 levels of "gray". This is much better than the 5 levels used by Windows 9x/98/NT/2000 or FreeType 1.
- FreeType 2 supports all the character mappings defined by the TrueType and OpenType specification. It is also capable of automatically synthetizing a Unicode charmap from Type 1 fonts, which puts an end to the painful "encoding translation" headache common with this format (of course, original encodings are also available in the case where you need them..).
- The FreeType 2 core API provides simple functions to access advanced information like glyph names or kerning data.
- A full-featured and efficient TrueType bytecode interpreter. The engine is able to produce excellent output at small point sizes. This component has been extremely difficult to get right, due to the ambiguous and misleadings TrueType specifications. However, we now match Windows and Mac qualities. Please read our Patents page to learn more about some issues when using the interpreter.
- For those who dont need or want to use the bytecode interpreter for TrueType fonts, we developed our own automatic hinter module. It is also used by other scalable formats.
- FreeType 2 provides information that is often not available from other similar font engines, like kerning distances, glyph names, vertical metrics, etc..
- Due to its modular design, its easy to enhance the library to provide additional format-specific information through optional APIs (as an example, an optional API is provided to retrieve SFNT tables from TrueType and OpenType fonts).
- FreeType 2 provides its own caching subsystem since release 2.0.1. It can be used to cache either face instances or glyph images efficiently.

GOCR is an OCR (Optical Character Recognition) program, developed under the GNU Public License. It converts scanned images of text back to text files. Joerg Schulenburg started the program, and now leads a team of developers.

GOCR can be used with different front-ends, which makes it very easy to port to different OSes and architectures. It can open many different image formats, and its quality have been improving in a daily basis.

GOCR or JOCR?

The original name is GOCR. Its what is used internally in the sources. But, when registering the site at Sourceforge, gocr was already taken. So, its kind of both. Yeah, we know.

Some examples of how you can use gocr:

gocr -h # help
gocr file.pbm # minimum options
gocr -v 1 file.pbm >out.txt 2>out.log # generate text- and log file
djpeg -pnm -gray text.jpg | gocr - # using JPEG-files
gzip -cd text.pbm.gz | gocr - # using gzipped PBM-files
giftopnm text.gif | gocr - # using GIF-files
gocr -v 1 -v 32 -m 4 file.pbm # zoning and out30.bmp output
xli -geometry 400x400 out30.bmp # see details using xli (recommanded viewer)
wish gocr.tcl # X11-tcl/tk-frontend (development version)
# see manual pages for more details

gprof2dot.py script can convert the output from gprof into a dot graph. It can correctly parse C++ template function names, allows you to prune nodes and edges below a certain threshold, can parse the special notation gprof uses for mutually recursive functions, uses color efficiently to draw attention to hot-spots, and works on any platform where GNU gprof, graphviz, and Python are available, i.e. virtually anywhere.
Main features:
- can correctly parse C++ template function names;
- allows to prune nodes and edges below a certain threshold;
- can parse the special notation gprof uses for mutually recursive functions;
- uses color efficiently to draw attention to hot-spots;
- works on any platform where GNU gprof, graphviz, and Python is available, i.e, virtually anywhere.
Usage:
gprof2dot.py [options] [file]
Options:
--version show programs version number and exit
-h, --help show this help message and exit
-o FILE, --output=FILE
output filename [stdout]
-n PERCENTAGE, --node-thres=PERCENTAGE
eliminate nodes below this threshold [default: 0.05]
-e PERCENTAGE, --edge-thres=PERCENTAGE
eliminate edges below this threshold [default: 0.01]
-c COLORMAP, --colormap=COLORMAP
color map: color, pink or gray [default: color]
-s, --strip strip function parameters, template parameters, and
const modifiers from demangled C++ function names
-w, --wrap wrap function names
Enhancements:
- The output produced by gprof with the static call graph option is now handled.
- The ability to read output generated by the Python profilers was added.

XRally project is a X11 clone of the Rally X arcade game.
In Rally X, you control a blue car which has to run through a maze-like level collecting flags and avoiding colliding with enemy (red) cars. In order to protect itself, the blue car can discharge clouds of smoke which stun the enemy cars for a while.
The enemy cars can also crash into each other, what gives you some extra time. One of the main features of XRally is that it is fully customizable.
You can create custom tilesets and levels and load them at run time, changing the entire look of the game. (You could, for instance, create a water tileset, using boats instead of cars.)
Enhancements:
- Added the Easy Level, that should be suitable for begginners
- Fixed bug in the radar display (was displaying some weird green lines)
- Fixed some segfaults, added others
- Updated xpm2xrally a bit more forgiving about the xpm file syntax
- And now it outputs the maps on the new map format
- Changed the maps a bit (some of them were way _too_ hard)
- Removed some unecessary stuff
- Added a xm2mod utility, to convert xm music to mod (XRally format)
- Added a Intro tune
- Added a new level option, "resol", the sets how many tiles are painted on the screen at a time (see a example on the Leo Level)
- Added html documentation, written by Josh Franklin
- sound now works on PowerPC
- Debian files added to the main repository to make debian package maintenance easier.
- Loads of sounds enhancements
- Fixed bug when the player wasnt receiving his extra lives (some changes of
- score.value didnt check for it)
- Changed the layout of the info bar, now contains the level name, the number of the current map, the total number of maps and the hiscore for this level
- Some code cleanup
- Added ANSI color codes to debug messages
- Changed the intro menu
- Added a big nice background image
- Added blending effect to the menu.
- Added shading/unshading effect to the meu.
- Changed the position of all the item/texts
- Indentation fixes (using tabs instead of spaces)
- Added blended windows to splash screen messages, hiscores messages and in-game windows
- Changed the default border color from a window from red to gray (is that border necessary?)
- Changed the layout of the splash screen (to take advantage of all the new screen space)
- Added a more informative level description (w/ the speed of the cars on the first map)
- Slowed down the default speed (from 12 to 9)
- Displays menu help on the main menu screen
- Displays game help on the splash screen
- Changed the graphics API
- Changed some of the FPS counting routines (now it should be better to benchmark the game)
- Displays Expected frame len and Real frame len on end of map (good to see if your computer is fast enough to play the game)
