A free COBOL compiler
GnuCOBOL (formerly OpenCOBOL) is a free COBOL compiler. cobc translates COBOL source to executable using intermediate C, designated C compiler and linker. OpenCOBOL 1.1 became GNU Cobol 1.1 in 2013. Official releases at ftp://ftp.gnu.org/gnu/gnucobol GnuCOBOL 2.2 is the last release, version 3.0 is on its way. A programmer's guide, by Gary Cutler, and other documentation, is indexed at http://open-cobol.sourceforge.net/ OpenCOBOL was written by Keisuke Nishida and Roger While, from 2001 to 2012. GnuCOBOL is also authored by Simon Sobisch, Ron Norman, Edward Hart, Sergey Kashyrin, Dave Pitts and Brian Tiffin. Others listed in the AUTHORS and THANKS files.

Volocian believes first and foremost that financial status shouldn’t be a barrier to entry in multimedia content creation. Whether you want to design a product or website, record a band, remix a song, or produce a feature length movie with professional post production graphics and effects, Volocian™ wants to help, even if you’re using borrowed hardware with no previous experience. We provide affordable products and services for any budget, including cost-free solutions for education and demo purposes, while everything we do is designed with ease of use and flexibility in mind, to suit everyone from novice hobbyists to expert professionals. Wherever possible, Volocian™ relies on free, open source, and cross-platform software to prevent vendor lock-in, planned obsolescence, and software as a service licensing. While we remain pragmatic about the use of proprietary software, as we’re aware of the feature limitations of some open source solutions, free solutions are preferred.
The "Img" package adds a lot of image formats to Tcl/Tk.
System dynamics program with additional features for economics
Minsky enables the simulation of models (particularly from economics) defined in terms of coupled ordinary differential equations. The models are defined using a drawing canvas (rather like VisSim), and a double entry bookkeeping system known as a Godley table.
ChessDB is a free open-source chess database for Windows, Linux, Mac OSX and most UNIX and UNIX-like operating systems. ChessDB is based on code from Scid http://scid.sourceforge.net/ - a project for which there have been no updates for several years. In

Exploration and categorization of CREs and CRMs
Cis-regulatory elements (CREs) and cis-regulatory modules (CRMs) play an important role in temporal and spatial regulation of gene expression, which is a common process in eukaryotic organisms. We developed two programs that serve as exploratory tools in the analysis of CRM-mediated control of gene expression: “Exploration of Distinctive CREs and CRMs” (EDCC) and “CRM Network Generator” (CNG). EDCC correlates the presence and positions of CREs/CRMs with gene expression data and identifies candidate regulatory elements for further functional analysis. CNG provides an unbiased neural network approach to assess the importance of positional features that were determined by EDCC. To sustain a high computational performance even for large datasets, the mostly in Python 3 written programs use k-mer based indexing, parallelization and a neural network approach for categorization.

Yet Another Diff Tool
YaDT - Yet another Diff Tool. It is another front-end for diff and in earlier versions diff3 utility. With YaDT you can compare and merge 2 and/or 3 files. YaDT is written on Tcl/Tk and wrapped in a single executable file with the help of sdx and tclkit. diff and cvs utilities are embedded inside YaDT. Also, YaDT supports Git and Mercurial repositories, but git and hg are not embedded inside YaDT, you should have git/hg executable in your path environment.
