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

Xschem is a schematic capture program, it allows to create a hierarchical representation of circuits with a top down approach . By focusing on interconnections, hierarchy and properties a complex system (IC) can be described in terms of simpler building blocks. A VHDL, Verilog or Spice netlist can be generated from the drawn schematic, allowing the simulation of the circuit. Key feature of the program is its drawing engine written in C and using directly the Xlib drawing primitives; this gives top speed performance, even on very big circuits. I have succesfully managed to simulate complete VLSI projects with this tool, both digital (Verilog / VHDL) and analog (Spice). Schematics can be printed in SVG, PNG, PDF, formats. XSCHEM runs on Linux or other Unix-likes with Xorg server and on Windows with the Cygwin layer and required tools installed. Can be found also on github: https://github.com/StefanSchippers/xschem

An open source COBOL compiler for the PC x86-32 platform. Generates GNU assembler and requires GCC to produce a binary. Supports Linux, BSD and MinGW 32 bit platforms.

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.

This software is a set of tools that hides C source code in txt files. Also the software is able to restore the txt files to C source code again. This work is based on the tool c2txt2c by Leevi Martilla. Csteg needs a book file in txt format to hide C so

A re-implementation of the LISP-like 'Installer' scripting language included with AmigaOS as of version 2.1. InstallerLG aims to be fully compatible with the original as described in the V43.3 documentation. Most of the resource related limitations of the Commodore implementation are gone and the GUI has been replaced by a MUI / Zune based one.

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.

A group of tools to analyze logfiles for qmail, tinydns, dnscache, rbldns, axfrdns and publicfile.

xacc.ide is a opensource IDE aimed at mainly .NET development. It has a code editor written in 100% C# code, which is faster than most commercial offerings.

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

Kure is a C library which provides manipulation of relations and operations of relation algebra using a fast implementation using binary decision diagram. It provides a Lua based domain-specific embedded programming language to conveniently manipulate and work with relations. For instance, given relations R, S, the tupling of them can be computed using [R,S] and they can be composed using R*S.

Mutabor is a Program that allows performing and composing microtonal music using a normal MIDI keybord. But it's powerful description language is intended to allow permanent retunings and tuning logics in to describ, what's actually goes on.

amilab is a tool for image processing that includes its own scripting language, and an interface for visualizing 2d/3d images and 3d surfaces. Its main application is medical image processing.

AVInfo is a program that reports on multimedia files. It recognizes the following file formats: AVI, MKV, MPEG, MP3, OGM, IFO (DVD), and the subtitle files. AVInfo can be used in batch mode with file lists as well as with single files.

Aquamarine is a Object Oriented language. The goal of this project is to provide a aquamarine to C++ compiler and a classes library.

Simple PHP compiler for a university subject.
