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. GnuCOBOL 2.2 is the latest, version 3.0 is on its way. A programmer's guide, by Gary Cutler and Vincent Coen, is indexed at https://open-cobol.sourceforge.io together with more documentation. 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.

Video mixer for mixing live and recorded video and audio feeds
New version 0.5.1 Released February 9th 2016. Snowmix is a Swiss army knife tool for mixing live and recorded video and audio feeds. It supports 2D and 3D clipping, scaling and transparent overlay of video, png graphics and text. It supports animation of video, images and texts through native commands changing scale, placement, transparency and rotation. Animation and actions can also be controlled through native scripting and an embedded Tcl interpreter. Snowmix is designed for control over low bandwidth links and can work as a standalone CLI based program. Control over both CLI and a TCP connections. Input and outputs can be done through GStreamer pipelines or the GStreamer shmsrc/shmsink API. OS X on Intel and Linux on amd64/i386/i686/ARMv7 and FreeBSD on amd64 supported. Ubuntu/Fedora/Mint/Debian/Chakra/CentOS/OpenSUSE and Linero is supported. Free support in the discussion forum. See Snowmix in action on Youtube http://www.youtube.com/user/Snowmix4video
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.
GUI for rayinvr modelling
PRay stands for 'Plot Rayinvr' and is a graphical user interface for the ray-tracing software rayinvr (Zelt & Smith, 1992). In principle it can also be used as viewer for seismic traveltime data from other software like tomo2D. Zelt, C. A. and Smith, R. B., 1992, Seismic traveltime inversion for 2-D crustal velocity structure, Geophysical Journal International, 108(1), 16--34, 10.1111/j.1365-246X.1992.tb00836.x SYSTEM/USER REQUIREMENTS: - Linux/Mac OS X - You do need to be familiar with command line operations. - a running rayinvr installation DOWNLOAD AND INSTALLATION: Please use the svn repository to download the code: svn checkout svn://svn.code.sf.net/p/pray-plot-rayinvr/code/trunk/ path/to/your/installation To install follow the instructions in the downloaded file 'install.readme'
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.

Perl Web Scraping Project
Web scraping (web harvesting or web data extraction) is data scraping used for extracting data from websites. Web scraping software may access the World Wide Web directly using the Hypertext Transfer Protocol, or through a web browser. While web scraping can be done manually by a software user, the term typically refers to automated processes implemented using a bot or web crawler. It is a form of copying, in which specific data is gathered and copied from the web, typically into a central local database or spreadsheet, for later retrieval or analysis. Web scraping a web page involves fetching it and extracting from it. Fetching is the downloading of a page (which a browser does when you view the page). Therefore, web crawling is a main component of web scraping, to fetch pages for later processing. Once fetched, then extraction can take place. The content of a page may be parsed, searched, reformatted, its data copied into a spreadsheet, and so on.
