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.

NETGEN is an automatic 3d tetrahedral mesh generator
NETGEN is an automatic 3d tetrahedral mesh generator. It accepts input from constructive solid geometry (CSG) or boundary representation (BRep) from STL file format. The connection to a geometry kernel allows the handling of IGES and STEP files. NETGEN contains modules for mesh optimization and hierarchical mesh refinement. Netgen is open source based on the LGPL license. It is available for Unix/Linux and Windows.
UniConvertor is a universal vector graphics translator. The project uses sK1 engine to convert one format to another. It has an import filters for: CDR, CDRX, CDT, CMX, AI, CGM, WMF, XFIG, SVG, SK, SK1, AFF and export filters: AI, SVG, SK, SK1, CGM, WMF.
Cross-platform, scientific graphics plotting library
PLplot is a cross-platform, scientific graphics plotting library that supports math symbols and human languages (via UTF-8 user input strings); plot capabilities for multiple non-interactive plot file formats and in multiple interactive environments; and bindings for multiple computer languages.
RawGeno Version 2.0-1 is released! RawGeno is an R CRAN library automating the scoring of AFLP electropherograms. The library includes a graphical user interface to simplify its use. Note that the 2.0-1 version is delivered as a source (*.tar.gz for Linux and Mac users) and as a binary file (*.zip, for Windows users). The installation procedure differs slightly according to your system; but this should remain simple. Have a look at the readme file when you download your new copy from https://sourceforge.net/projects/rawgeno/files/rawgeno/RawGeno%202.0-1/ Make also sure to have a look at https://sourceforge.net/projects/rawgeno/files/ where you can find a detailed manual, demo datasets and many demo scripts.
