Yet another Basic for Unix and Windows
Yabasic implements the most common and simple elements of the basic language; It comes with goto/gosub, with various loops, with user defined subroutines and Libraries. Yabasic does monochrome line graphics and printing. Yabasic runs under Unix and Windows; it is small (around 200KB) and free.
High-performance Prolog compiler
YAP is a high-performance Prolog compiler developed at LIACC/Universidade do Porto and at COPPE Sistemas/UFRJ. Its Prolog engine is based in the WAM (Warren Abstract Machine), with several optimizations for better performance. YAP follows the Edinburgh tradition, and is largely compatible with the ISO-Prolog standard and with Quintus and SICStus Prolog.

Interpreted language for scientific simulations
Yorick is an interpreted programming language for: * Scientific simulations or calculations * Postprocessing or steering large simulation codes * Interactive scientific graphics * Reading, writing, and translating large files of numbers The language features a compact syntax for many common array operations, so it processes large arrays of numbers very quickly and efficiently. Superficially, yorick code resembles C code, but yorick variables are never explicitly declared and have a dynamic scoping similar to many Lisp dialects. The yorick language is designed to be typed interactively at a keyboard, as well as stored in files for later use. This package includes an emacs-based development environment, which one can launch by typing M-x yorick in emacs, if installed `yorick.el' have been loaded into one's ~/.emacs file.
Minimalist implementation of python in 64k of code
tinypy is a minimalist implementation of python in 64k of code it includes a whole heap of features: * parser and bytecode compiler written in tinypy * fully bootstrapped * luaesque virtual machine with garbage collection written in C it's "stackless" sans any "stackless" features * cross-platform :) it runs under Windows / Linux / OS X * a fairly decent subset of python o classes and single inheritance o functions with variable or keyword arguments o strings, lists, dicts, numbers o modules, list comprehensions o exceptions with full traceback o some builtins * batteries not included -- yet
Open source JavaScript engine by Google
V8 is Google's open source JavaScript engine. V8 is written in C++ and is used in Google Chrome, the open source browser from Google. V8 implements ECMAScript as specified in ECMA-262, 5th edition, and runs on Windows (XP or newer), Mac OS X (10.5 or newer), and Linux systems that use IA-32, x64, or ARM processors. V8 can run standalone, or can be embedded into any C++ application. Git repository at https://github.com/v8/v8
Scheme implementation for real-time applications
Ypsilon is an implementation of Scheme programming language for real-time applications, which conforms to the latest standard R^6RS. Ypsilon features mostly concurrent garbage collector optimized for systems with multiple CPUs, and an easy to use FFI.

Sass is an extension of CSS3
Sass is an extension of CSS3, adding nested rules, variables, mixins, selector inheritance, and more. It's translated to well-formatted, standard CSS using the command line tool or a web-framework plugin.
