ANother Tool for Language Recognition (ANTLR) is the name of a parser generator that uses LL parsing. ANTLR is the successor to the Purdue Compiler Construction Tool Set (PCCTS), first developed in 1989, and is under active development. Its maintainer is professor Terence Parr of the University of San Francisco....

Pardus is a GNU/Linux distribution developed by BTE/TUBITAK according to computer literates' basic desktop needs; uses existing distributions' dominant parts as concept, architecture or code; provides easy use, configuration, installation with configuration environment and tools that can be converted to an autonomous system....

Berkeley DB (BDB) is a high-performance, embedded database library with bindings in C, C++, Java, Perl, Python, Tcl, Smalltalk and many other programming languages. BDB stores arbitrary key/data pairs as byte arrays, and supports multiple data items for a single key. BDB can support thousands of simultaneous threads of control or concurrent processes manipulating databases as large as 256 terabytes, on a wide variety of systems including most UNIX-like and Windows systems as well as real-time operating systems....

PROJ.4 - Cartographic Projections library,

GNU Parted is an industrial-strength package for creating, destroying, resizing, checking and copying partitions, and the file systems on them. This is useful for creating space for new operating systems, reorganising disk usage, copying data on hard disks and disk imaging....

xu‧ggle (zŭ' gl) v. To freely encode, decode, and experience audio and video.

With Xuggle you can write Java programs that decode or encode video.

It incorporates FFMPEG, but adds a simpler interface that is safe to use from Java-like languages (e.g. garbage collection) and tries hard to make sure usage of FFMPEG features doesn't crash a JVM....

tmux is a "terminal multiplexer", it enables a number of terminals (or windows) to be accessed and controlled from a single terminal. tmux is intended to be a simple, modern, BSD-licensed alternative to programs such as GNU screen.

GnuCash is personal and small-business financial-accounting software, freely licensed under the GNU GPL and available for GNU/Linux, *BSD, Solaris and Mac OSX.

Designed to be easy to use, yet powerful and flexible, GnuCash allows you to track bank accounts, stocks, income and expenses. As quick and intuitive to use as a checkbook register, it is based on professional accounting principles to ensure balanced books and accurate reports....

LLVM is a robust system, particularly well suited for developing new mid-level language-independent analyses and optimizations of all sorts, including those that require extensive interprocedural analysis. LLVM is also a great target for front-end development for conventional or research programming languages, including those which require compile-time, link-time, or run-time optimization for effective implementation, proper tail calls or garbage collection. We have an incomplete list of projects which have used LLVM for various purposes, showing that you can get up-and-running quickly with LLVM, giving time to do interesting things, even if you only have a semester in a University course. We also have a list of ideas for projects in LLVM....

Doxygen is a documentation system for C++, C, Java, Objective-C, Python, IDL (Corba and Microsoft flavors), Fortran, VHDL, PHP, C#, and to some extent D.

Doxygen is developed under Linux and Mac OS X, but is set-up to be highly portable. As a result, it runs on most other Unix flavors as well. Furthermore, executables for Windows are available....
