Icarus Verilog is an open source Verilog compiler that supports the IEEE-1364 Verilog HDL including IEEE1364-2005 plus extensions.

A read-only JDBC driver for Java that uses Comma Separated Value (CSV) files as database tables. Ideal for writing data import programs and conversion programs.

After a program has been thrown into the world in binary form, it can boomerang back as source code. The Boomerang reverse engineering framework is the first general native executable decompiler available to the public.

BeeBase is a relational, programmable database system with graphical user interface for Windows, Mac, Linux and Amiga.

Sieve is a mail filtering language standardized as RFC 3028 / RFC 5228 and its extensions. libSieve provides a simple, clean API for parsing and executing Sieve scripts. Code is on GitHub: http://github.com/sodabrew/libsieve

This is a suite of mathematical software solvers interface on DLV and other command-line solvers. It helps researchers and students to better comprehend their declarative definitions published on papers. The user can have links to the related papers and to the software of the corresponding definitions.

ONSlaught is an ONScripter clone with Unicode support and other features. Its aim is to completely replace ONScripter as an open source visual novel engine by providing a completely new design and new features.

Gimp User Filter is a plugin for The Gimp (http://www.gimp.org/), originally written by Jens Restemeier back in 1997. This project is about maintaining the plugin, keeping it compatible with current versions of Gimp, and eventually extending its features

Two experimental AI languages - Perkun and its successor Wlodkowic. Attempt to maximize the expected value of the payoff function by appropriate choosing the actions (output variables values). The package contains also a tool called zubr - a Java code generator based on Perkun. Take also a look at my blog: http://pawel-biernacki.blogspot.fi/ For Windows users there is an installer: http://www.pawelbiernacki.net/perkun.msi

Blackboard implements a lightweight, portable tuple space suitable for multi-agent system and distributed component design. Supports implicit invocation via content-filtered asynchronous events, blocking call semantics, and shared memory messaging.

Wtparser is a lex/yacc-based parser for wikitext as defined by mediawiki.

GRAMophone is an algorithmic generator of music composition. The music is generated using two kinds of formal grammar: Chomsky’s grammar for TOP DOWN approach to the composition and a reduced version of Lindenmayer grammar for BOTTOM UP approach.

The Green Engine was designed as an introduction to programming and game development for those who have little or no previous experience. The games developed using this system are described in a high level, simple to use scripting language.

March 2013 this project was announced first to public, but the feedback was ZERO. So I guess it is insanely bad and unusable. Ok. But sorry, I decided to continue it for myself to improve my inability and unexperience in software development FOR MYSELF. Even if it seemed to be the worst thing ever, I *NEED* to develop software for my own well being and even if I apparently - after over 20 years since the first lines of code I wrote - I improved my ability not a single bit than it is like that and I can't change it. BTW: there was feedback indeed: from the own 'family': "it is done by YOU so it cannot be of use for anybody!" (Literally: it contains algorithms and algorithms are evil and are non-existent in usable software)

The Ivory Programming Language: A modern language for systems programming

Pear3DEngine is a modern and modular 3D development framework that lets you create professional games, simulations and more. You are free to develop your program in C + +, XML or LUA and publish it as open source software or selling it as a commercial program. The rendering engine uses internally OpenGL or DirectX optionally. The planned editor supports software development on Linux, Windows and maybe MacOS X. DirectX 9 and therefore Windows XP are currently not supported and support is not planned in the future. One goal of the Pear3DEngine Framework is to use the latest and most promising algorithms and techniques from the 3D and IT scene.

This project compiles sql_yacc.yy from the MySQL source using Parse::YAPP and creates a stand-alone pure-perl parser for MySQL statements.

A parsing toolkit that supports both top-down (LL(1) and Simple Precedence) and bottom-up parsing (LR(0), SLR(1), LR(1) and LALR(1)). The toolkit supports generating Java parsers for all the bottom-up parsing methods, based on a CUP definition.

A compiler library for a language integrating all that is needed for completely defining whole sound/music compilations. From very basic stuff as defining oscillators etc in all their parameters up to note events and more.

The CCC Language is yet another programming language. It is platform-independent, compact, and robust. Supports many SQL engines, has own ISAM DB engine, has terminal mode and more UI-s, is object-oriented, but it is compiled and not interpreted.

WebCleaner is a filtering HTTP proxy. It removes adverts, compresses documents, deanimates GIFs, can use SquidGuard filter lists, and more. It is easy to configure with a web interface.

cantools is a set of libraries and command line tools for handling ASC, BLF, CLG, VSB, MDF, and DBC files. The tools can be used to analyze and convert the data to other formats. Shared libraries for parsing and accessing these files are also provided.

Calculates the total number of source code changes between two source code directories. Also enlists the number of source code lines added, removed and modified.

freejava is a bundle of tools for programming java easier and faster!
