xlife is a laboratory for experimenting with cellular automata. It supports loadable rulesets and palettes, different topologies, and up to 256-state cellular automata. It has rules and patterns for Life, Brian's Brain, Perrier's Loops, Langton's Ants and Loops, Wireworld, E.F. Codd's 1975 UCC automaton, some Prisoner's Dilemma games, and many others. It is very fast for step-by-step mode, bounded grid, and chaotic patterns. It has several unique features: a historical mode, a pseudocolor mode, and n-state statistics. It has been developed since 1989. The modern version of Xlife began its history in 2011.
myKnowledgeExplorer (mKE) is an intelligent knowledge base assistant. All communication is in a user-friendly, English-like language called mKR. mKR is designed to help human beings work more intelligently. mKE command line options include language definitions for RDF, OWL, CYC, and SUMO. mKR scripts may include embedded calls to the Unix shell. mKR gives special emphasis to context hierarchies, genus-differentia definitions, n-ary relations, questions, and action/methods.
GODI provides an advanced programming environment for the Objective Caml (O'Caml) language. From INRIA (who created O'Caml) you can get the O'Caml compiler and runtime system, but this is usually not enough to develop applications. You also need libraries, and there are many developers providing them. But it is a lot of work to build and install them. GODI is a system that simplifies this task: It is a framework that automatically builds the O'Caml core system, and additionally installs a growing number of pre-packaged libraries. For a number of reasons, GODI is a source-code based system, and there are no precompiled libraries, but it makes it very simple for everybody to compile them.
Kallimachos is a simple Web-based digital book-catalog intended for personal use. Books are indexed by title, author, translator, edition, genre, page number, and ISBN. You can insert a new book, enter the library, and search by any item. It also provides a system-info viewer. The installation is quick and simple, and the program has a user-friendly interface.
Trans (short for Transmuter Programming Language) is an extremely dynamic, biologically-inspired prototyping language providing a framework for experimenting with naturally evolving systems of objects over the net, and for exploring new ideas about recombinant software, code morphing, and evolutionary programming. Trans is also a very capable general-purpose programming language. It's fast, flexible, compact, object-oriented, highly extensible, and easy-to-learn. It can be used for rapid prototyping, or as a scripting language, an embedded language, a network server or client, a system of cooperating network nodes, a real-time control and monitoring system, and more.
The d command runs a command in the background and redirects its output to a file. The output file is annotated with start and end time, the actual command used, cwd, host, etc. You can ask the d command to extract the last command from the output file and run it again, you can ask it to append to the file or not, and other goodies. It comes with handy little programs to look at the output, tail it, etc. It is sort of trivial, but has been streamlined over many years.
