Free x factor software for linux

Factor project is a language based around a programming paradigm that encourages simple, testable and reusable code.
Factors main influences are Joy for the syntax, Forth for the implementation techniques, and Lisp for the object model. The source is released under a BSD-style license. Share it freely.
Main features:
- Runs on FreeBSD, Linux, Mac OS X and Windows.
- Native code compiler for x86 and PowerPC.
- Minimal postfix syntax with an extensible parser.
- Image-based environment offering orthogonal persistence.
- Polymorphism through predicate-based dynamic dispatch.
- Language support for delegation-based design patterns.
- Data structures include linked lists, vectors, and hashtables.
- User-defined types, known as tuples.
- Rich math library including big integers, floating point, ratios, complex numbers.
- Continuations.
- Profiling, tracing, single-stepping, browsing.
- Static stack effect inference.
- HTTP server and continuation-based web framework.
- C library interface.
- SDL graphics library interface.
- Focus on interactive and test-driven development.
- A plugin for the jEdit text editor offers a powerful development environment.
Reflection
Factor is defined in terms of itself as much as possible. Every layer of the system is inspectable and editable at runtime. Everything in the system carries consistent object semantics, and every object can be queried for its type and shape.
Metaprogramming
A powerful meta-level takes advantage of the duality between code and data. The object system, and even tools such as steppers, browsers, inspectors and profilers are built within the language framework.
Transparency
Nothing is hidden from the programmer. Factor is designed not as a black box, but a tool box. The programmer is encouraged to mold the language to fit the problem.
Simplicity
Everything is as simple as possible. The system should be small enough that one person can study the code and understand it completely. Unnecessary code and features are not included.

Firestorm is an extremely high performance network intrusion detection system (NIDS). At the moment it just a sensor but plans are to include real support for analysis, reporting, remote console and on-the-fly sensor configuration. It is fully pluggable and hence extremely flexible. Firestorm performs a lot better than all other systems I have tested (such as snort and prelude) by as much as a factor of 2 (and thats under favourable conditions, it way outstrips the competition under a targeted DoS attack).
A Network Intrusion Detection System is a system which can identify suspicious patterns in network traffic. If a firewall is a doorman, a NIDS is an undercover KGB agent. He silently gathers intelligence and can watch an enemy even if the door security has already let them in (maybe the enemy can make fake identification documents).
Tested Platforms
Linux 2.x
FreeBSD 4.x
OpenBSD
Solaris
Should compile and run on any mainstream UNIX really...

- Comprehensive snort rule support
- Wu-Manber setwise string matching
- Easy to configure; just one config file
- Can run chroot and with lowered privs (when started as root)
- Can run as a realtime process (when started as root)
- Preprocessors to allow supplementary modes of detection (eg: anomaly)
- Full IP defragmentation (passes fragroute evasion tests)
- TCP stateful inspection with window tracking
- Intelligent TCP stream reassembly
- HTTP URL normalization
- EXTREMELY fast and scalable signature engine
- Configurable token-bucket rate-limiting of any alerts
- GNOME2 based analyst console user interface
- Enhanced logging format for ease of analysis
- ELOG indexing for lightning fast sorting and filtering of alerts

JPEG Fit is a PHP class that can be used to optimize images to fit within a given file size limit. The project takes a picture in any format supported by the GD library and generates a JPEG picture with the maximum quality factor that makes the picture file size not exceed a given limit.

This class is similar to the JPEG Reducer class. It uses the binary search algorithm to reach the ideal quality factor in the smallest number of iterations.

The class stops searching when a given number of limit iterations is reached, or when the quality factor difference between the ideal and the found values is less than the configured precision value

IFT project is a simple flight simulator.
IFT is a small flight simulator written for the purpose of training pilots not experienced in instrument flight. It includes a couple of VOR and NDB stations and displays. These can be used to exercise basic radio navigation skills.
Its made and tested on GNU/Linux, but it should work on all Unices, since all it uses is the X11 library.
Version restrictions:
- Time factor should not be greater than 20 when you are entering a turn. It will never stop turning if you do so.
- There are only 4 stations defined statically in the source code. There could be more and they could be both dynamically placed & selectable into the radio navigation equipment.
- Its just a weeks hack. Im sure there are many bugs.

Styx is a scanner and parser generator designed to address some shortcomings of the traditional lex/yacc combination.
It has unique features like automatic derivation of depth grammar, production of the derivation tree including its C interface which provides access to the abstract syntax tree, preservation of full source information and pretty printing to faciliate source-source translation, persistence to aid rapid interpreter writing.
For application in contemporary computing environments, it supports unicode, reentrancy and offers thread-safeness.
Last but not least, Styx works well under many different OSes, among them dos, windows, and serveral unixes.
It has been successfully used in many applications and is known to provide rapid compiler development. Both from our practical experience as well as from the amount of written code, the gain in development time for realistic languages versus lex/yacc is a factor of about 5-10.
Enhancements:
- fixes panic mode error recovery
- fixes token buffer restriction. The token length is now of type long.
- hopefully fixes some configure problems on freeBSD (concerning libdl)
- adds parsing support for binary files

jPdfCalendar project allows you to create printable calendar pages as a PDF document from any of your images. The iText library is used to create the PDF itself.
You can add your own "special days" for each month, customize colors, fonts, borders etc.
To create calendar file, you should prepare xml file which structure is described in dtd file. The dtd structure also is described in graphical manner in image file. These information can be found in dtd folder.
To create a sample, use bin/createme.sh script. This script will create sample/calendar_public_en_2007.pdf file according to sample/calendar_public_en.xml project and with images from sample/pictures folder.
Requirements
You need Java 1.5 (or higher) JRE in your OS.
This tool uses iText library (http://www.lowagie.com/iText/) to manipulate of PDFs.
Well-known problem
If image is too large, especially if a hight of image large when page hight, the auto scaling works not properly (the day table is pulled out on the next page). In this case it is necessary to use "scale" tag and set scale factor manually.
Additional tool
Also here is some additional tool, PdfImageRipper. This tool has been created to extract (rip) images from PDF files.
It uses iText functionality to do it and you can think about it as Front-End-Tool. To use this tool, get bin/imgrip.sh script.
Enhancements:
- Moon phases are now displayed in the days table.
- The first day of week is now dependent on the locale, but can be changed in XML.
