For full, incremental, compressed and encrypted backups or archives
DAR is a command-line backup and archiving tool that uses selective compression (not compressing already compressed files), strong encryption, may split an archive in different files of given size and provides on-fly hashing. DAR knows how to perform full, differential, incremental and decremental backups. It provides testing, diffing, merging, listing and of course data extracting from existing archives. Archive internal's catalog, allows very quick restoration of a even a single file from a very large, eventually sliced, compressed and encrypted archive. Dar saves *all* UNIX inode types, takes care of hard links, sparse files as well as Extended Attributes (MacOS X file forks, Linux ACL, SELinux tags, user attributes), it has support for ssh and is suitable for tapes and disks (floppy, CD, DVD, hard disks, ...) more details at: http://dar.linux.free.fr/doc/Features.html
OpenJUMP is a community driven fork of JUMP the "Java Unified Mapping Platform" GIS software. The original JUMP was developed by Vivid Solutions, released under GPL2 in 2003 and discontinued in 2006. During 2004 already some enthusiastic developers joined together to enhance further the features of JUMP. They launched an independent development branch called OpenJUMP. The name gives credit to the original JUMP development, and at the same time describes the objectives of this project to be fully open to anyone wanting to contribute. These days OpenJUMP is developed and maintained by (some few) volunteers around the globe. If you need functionality or even better want to contribute you are very welcome to contact us at our mailing list.

MAnool is Not an Object-Oriented Language
MAnool is Not an Object-Oriented Language MANOOL is a general-purpose programming language suitable for comfortable expression of complex algorithms, like those that can be found in CS research papers where a kind of pseudo-code is normally used. At the same time, it is conceived as a practical language in many situation suitable for running such solutions in production systems by providing decent control over performance characteristics and required computing resources while providing decent means from the software engineering point of view.
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. Others listed in the AUTHORS and THANKS files. Copyright 2001-2018 Free Software Foundation, Inc.

Middleware for distributed applications
The purpose of the project is to develop a portable programming framework that facilitates distributed and multi-threaded programming for C++, Java, and Python. MADARA was originally developed as an agent-based middleware specifically for real-time, distributed artificial intelligence, but is now more general purpose for distributed timing, control, knowledge and reasoning, and quality-of-service. MADARA is composed of several tools and middleware, and the main entry point into the system is the Knowledge and Reasoning Language (KaRL) Engine, which provides a real-time scripting language for nanosecond execution times hooked into a flexible transport layer for distributed reasoning. The KaRL engine also supports object-oriented C++, Java, and Python programming through Containers, classes that provide abstractions and references for variable location within the KaRL Knowledge Base. This project is currently in process of being ported from http://madara.googlecode.com.
The Earth System Modeling Framework provides high-performance software infrastructure and superstructure for the construction and coupling of climate, weather, and data assimilation applications.
object orientated scripting language
ObjectiveScript is an object orientated scripting language that tries to combine the speed of scripting with an object orientated syntax similar to Java and C++. The language offers native data types like bool, double, float, int and string as well as user defined object types and a system library with data types similar to the Java boxed types like Integer and String. Collections like List, Map, etc. can be used with object and value types and can also be used as raw types (i.e. List == List<Object>).
Bochs is a portable x86 PC emulation software package that emulates enough of the x86 CPU, related AT hardware, and BIOS to run Windows, Linux, *BSD, Minix, and other OS's, all on your workstation.
Time-dependent simulation of open and closed quantum systems
WavePacket is a program package for numerical simulation of quantum-mechanical wavepacket dynamics for distinguishable particles. It can be used to solve one or more (i.e. coupled channels) time-independent or time-dependent (linear) Schrödinger and Liouville-von Neumann-equations. Optionally accounting for the interaction with external electric fields within the semiclassical dipole approximation, WavePacket can simulate modern experiments using ultrashort light pulses in photo-induced physics or chemistry. WavePacket is especially suitable for teaching of quantum mechanics as well as for research projects in physics, chemistry, and scientific computing. The present C++ version is an object-oriented rewrite of the existing Matlab version aiming to be more flexible. In particular, the goals are easy handling of open and closed systems and support for unusual setups.

A selection of secondary working fluid properties are also available. Can also make use of REFPROP when available. In addition, calculations for Humid Air Properties based on ASHRAE RP-1485 are provided. Wrappers are available for MATLAB, Octave, Python, C#, Fortran and many more.
LiteSQL is a codegenerator and C++ library that integrates C++ objects tightly to relational database and thus provides an object persistence layer. LiteSQL supports SQLite3, PostgreSQL, MySQL and oracle as backends.
C++ Statistical ToolKit
STK++ (http://www.stkpp.org) is a versatile, fast, reliable and elegant collection of C++ classes for statistics, clustering, linear algebra, arrays (with an Eigen-like API), regression, dimension reduction, etc. Some functionalities provided by the library are available in the R environment as R functions (http://cran.at.r-project.org/web/packages/rtkore/index.html). At a convenience, we propose the source packages on sourceforge. The library offers a dense set of (mostly) template classes in C++ and is suitable for projects ranging from small one-off projects to complete data mining application suites.
Detection Classification and Localisation of marine mammals
The PAMGUARD project develops software to help detect, locate and classify marine mammals using Passive Acoustic Monitoring.
A Portable General-Purpose Computer Algebra System
REDUCE is an interactive system for general algebraic computations of interest to mathematicians, scientists and engineers. It can be used interactively for simple calculations but also provides a flexible and expressive user programming language. The development of the REDUCE computer algebra system was started in the 1960s by Anthony C. Hearn. Since then, many scientists from all over the world have contributed to its development. REDUCE has a long and distinguished place in the history of computer algebra systems. Other systems that address some of the same issues but sometimes with rather different emphasis are Axiom, Derive, Macsyma (Maxima), Maple, Mathematica and MuPAD. REDUCE primarily runs on either Portable Standard Lisp (PSL) or Codemist Standard Lisp (CSL), both of which are included in the SourceForge distribution. By modern standards, REDUCE is a surprisingly small and compact application, which runs well on all major operating systems.

Transmission Electron Microscope Image Simulation
These programs calculate high resolution conventional and scanning transmission electron microscope (CTEM, STEM) images of thin specimens from first principles using the multislice method for electrons in the energy range of approximately 100 keV to 1000 keV. The fundamental theory and usage are described in "Advanced Computing in Electron Microscopy" (Springer 2010) by Earl J. Kirkland. Please refer to this book for the theory of calculation and how to use these programs. computem uses a GUI and the temsim group uses a command line interface. The user is assumed to have some understanding of optics, Fourier transforms, electron microscopy and computer skills at the graduate or advanced undergraduate level.
