Socat is a relay for bidirectional data transfer between two independent data channels. Each of these data channels may be a file, pipe, device (terminal or modem, etc.), socket (Unix, IP4, IP6 - raw, UDP, TCP), SSL, a client for SOCKS4, or proxy CONNECT. It supports broadcasts and multicasts, abstract Unix sockets, Linux tun/tap, GNU readline, and PTYs. It provides forking, logging, and dumping and different modes for interprocess communication. Many options are available for tuning socat and its channels. Socat can be used, for example, as a TCP relay (one-shot or daemon), as a daemon-based socksifier, as a shell interface to Unix sockets, as an IP6 relay, or for redirecting TCP-oriented programs to a serial line.

TreeLine is used to organize and store text data in a tree structure. It is well suited to keeping track of many different types of information. Each node of the tree can contain several defined fields, forming a mini-database. The format of each node can be defined, and the output can be shown on the screen, printed, or exported to HTML. The tree structure is navigated and edited in the left pane of the window, while various views of the child data are shown and editable in the right pane. The data is stored in XML text files. TreeLine is based on the PyQt library.
GAMGI (General Atomistic Modelling Graphic Interface) is a program to build, view, and analyze atomic strucures such as molecules, crystals, glasses, liquids, etc. It aims to be useful for: the scientific community working in Atomistic Modelling that needs a graphic interface to build input data and to view and analyse output data, calculated with Ab-Initio and Molecular Mechanics programs; the scientific community at large studying chemistry, physics, materials science, geology, etc., that needs a graphic interface to view and analyse atomic structural information and to prepare images for presentations in classes and seminars; teaching chemistry and physics in secondary schools and universities; science promotion in schools, exhibitions and science museums.
The Advanced Bash Scripting Guide is both a reference and a tutorial on shell scripting. This comprehensive book, the equivalent of 1,000+ print pages, covers almost every aspect of shell scripting. It contains 382 profusely commented illustrative examples, a number of tables, and a cross-linked index/glossary. Not just a shell scripting tutorial, this book also provides an introduction to basic programming techniques, such as sorting and recursion. Included scripts are the Game of Life, a Perquackey variant, a Morse code trainer, and an implementation of the Gronsfeld Cipher. This book is suited for both individual study and classroom use. It covers Bash, up to and including version 4.2. Note that users of miniaturized single-board computers running Linux, such as the Raspberry Pi and the Beagle Bone, would find this Guide useful for learning and running Bash scripts to explore and expand the capabilities of these small, but powerful machines.
