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.

A program for fitting structural models to small angle scattering data
SASfit has been written for analyzing and plotting small angle scattering data. It can calculate integral structural parameters like radius of gyration, scattering invariant, Porod constant. Furthermore it can fit size distributions together with several form factors including different structure factors. Additionally an algorithm has been implemented, which allows to simultaneously fit several scattering curves with a common set of (global) parameters. This last option is especially important in contrast variation experiments or measurements with polarised neutrons. The global fit helps to determine fit parameters unambiguously which by analysing a single curve would be otherwise strongly correlated.

YouTube Downloader - Cross Platform
YouTube-DL-PyTK (formerly known as YouTube-DL-GTK) is just a graphical launcher for the popular youtube downloader youtube-dl . Its purpose is simple; to facilitate the downloading of non-copyright-protected videos from certain internet websites including YouTube. It is written in Python, so it should run on Windows and Linux systems alike. I don't have access to an Apple computer to test it on OSX, but it might also work on that platform. It includes the Windows and Unix version of youtube-dl, so there's no need for you to go download it yourself for this to work. This little project packages everything you need to start using it in one package, and all the appropriate licensing information is located in the archive. If you have ran the installer on Windows, you can find the source code and all of the documentation in the installation folder.

Analyze and visualize coupled residues and their networks in proteins
xPyder is a PyMOL plugin to analyze and visualize on the 3D structure dynamical cross-correlation matrices (DCCM), linear mutual information (LMI), communication propensities (CP), intra- and inter-molecular interactions (e.g. PSN), and more, to produce highly customizable publication-quality images. xPyder identifies networks (using concepts from graph theory, such as hubs and shortest path searching), compares matrices and focuses the analysis on relevant information by filtering the data using a modular, user-expandable plugin system that takes advantage of structural and dynamical information, contributing to bridge the gap between dynamical and mechanical properties at the molecular level.
