J is a modern, array oriented, high level, high performance, general purpose
programming language. J is used in a variety of industries including banking,
investment analysis, insurance, derivative trading, scientific research, and
Lua is a programming language originally designed for extending applications,
but also frequently used as a general-purpose, stand-alone language. Lua
combines simple procedural syntax (similar to Pascal) with powerful data
description constructs based on associative arrays and extensible semantics.
Lua is dynamically typed, interpreted from bytecodes, and has automatic memory
management with garbage collection, making it ideal for configuration,
scripting, and rapid prototyping.
A fundamental concept in the design of Lua is to provide meta-mechanisms for
implementing features, instead of providing a host of features directly in
the language. For example, although Lua is not a pure object-oriented
language, it does provide meta-mechanisms for implementing classes and
inheritance. Lua's meta-mechanisms bring an economy of concepts and keep the
language small, while allowing the semantics to be extended in unconventional
ways. Extensible semantics is a distinguishing feature of Lua.
Lua is implemented as a small library of C functions, written in ANSI C, and
compiles unmodified in all known platforms. The implementation goals are
simplicity, efficiency, portability, and low embedding cost.
mawk is an interpreter for the AWK Programming Language. The AWK language is
useful for manipulation of data files, text retrieval and processing, and for
prototyping and experimenting with algorithms. mawk is a new awk meaning it
implements the AWK language as defined in Aho, Kernighan and Weinberger, The
AWK Programming Language, Addison-Wesley Publishing, 1988 (hereafter referred
to as the AWK book.) mawk conforms to the Posix 1003.2 (draft 11.3) definition
of the AWK language which contains a few features not described in the AWK
book, and mawk provides a small number of extensions.
From Donald E. Knuth's MMIX page:
MMIX is a RISC computer designed by the author to illustrate
machine-level aspects of programming. In the next editions of his
books The Art of Computer Programming, MMIX will replace the
1960s-style machine MIX.
More details can be found in his book:

Mono is an open source implementation of .NET Development Framework. Its
objective is to enable UNIX developers to build and deploy cross-platform
.NET Applications. The project implements various technologies developed by
Microsoft that have now been submitted to the ECMA for standardization.
Mono provides the necessary software to develop and run .NET client and
server applications on BSD, Linux, Solaris, Mac OS X, Windows, and Unix.
This extension embeds Perl Interpreter into PHP.
It allows execute Perl files, evaluate Perl code,
access Perl variables and instantiate Perl objects.
The flat assembler is a fast and efficient self-assembling 80x86
assembler for DOS, Windows and Linux operating systems. Currently it
supports all 8086-80486/Pentium instructions with MMX, SSE, SSE2, SSE3
and 3DNow! extensions and x86-64 (both AMD64 and EM64T) instructions,
can produce output in binary, MZ, PE, COFF or ELF format. It includes
the powerful but easy to use macroinstruction support and does multiple
passes to optimize the instruction codes for size. The flat assembler
is self-compilable and the full source code is included.
execline is a very light non-interactive scripting language,
which is similar to /bin/sh. Simple shell scripts can be
easily rewritten in the execline language, improving performance
and memory usage. execline was designed for use
in embedded systems, but works on most Unix flavors.
execline features conditional loops, getopt-style option handling,
filename globbing, and more. Meanwhile, its syntax
is far more logical and predictable than the shell's syntax,
and has no security issues.
Expect is a program that performs programmed dialogue with other
interactive programs. It is briefly described by its man page, expect(1).
It uses pseudo-tty's to control the child processes, so it is not affected
by programs that refuse to read from stdin or pipes. (eg: passwd(1) etc).
f2c and its run-time library, libf2c.a, are a port of the
Fortran-to-C converter available from ftp.netlib.org. This
software was originally developed by AT&T, Lucent Technologies,
