PHPLIB is a base library for the PHP language. It contains class definitions that help in session tracking, manage persistent variables (just like ASP session-variables, only more flexible), can do authentication and permission checking and support shopping cart applications. Additional classes generate HTML code from database queries and similar features.
The Python/Tk Empire Interface (PTkEI) enables you to connect to empire 4.x.x (Wolfpack) servers. Empire is a real-time war game with long tradition. You can find out about Empire and currently running servers and other clients at its homepage. This client is an example for a truly portable cross-platform GUI, known to run on Unix, X11, Win32 and Mac. Additionally you do not give up any command line power as a player, but you have to to learn the empire commands to make use of this GUI client.
DB_Browser is a CGI tool for developers working with any relational database supported by Perl::DBI. It easily facilitates searching, editing, and adding to tables within a database. While it can be used as a regular interface to database data itself, it works well as a supplemental tool for developers creating their own primary interface.
TiK is a pure TCL/Tk implementation of AOL Instant Messenger (AIM). It has most of the features the native Win32 and Mac clients have, plus some extras. It includes a graphical buddy list display, full font support, graphical emoticons, away messages, buddy pounce, buddy ticker, IM/Chat capturing, message broadcasting, a GUI preferences system, and much more. TiK's expandable nature allows the addition of new features through packages.
DocWiz allows you to easily add JavaDoc comments to your Java source code. With DocWiz, there's no need to tediously hand-format JavaDoc comments, adding tags and comment structures for each method. DocWiz provides a list of all the fields, methods, interfaces, and classes defined in a Java source file. You can click on any of these code elements to display a fill-in form for information about code elements. In addition, DocWiz shows you an icon for uncommented code segments.
Ghostscript is a processor for PostScript and PDF files. It can rasterize these files to a wide variety of printers, devices for screen preview, and image file formats. Since applications tend to prepare pages for printing in a high-level format such as PostScript, most Unix users with low-level bitmap printers, such as inkjets, use GhostScript as part of the printing process. In addition, Ghostscript is capable of converting PostScript files, functionality comparable to Adobe Acrobat Distiller, but on the command line. In addition, Ghostscript is used for file import and viewing by a great many other applications, including xv, ImageMagick, gimp, and xdvi. Several GUI wrappers for viewing PostScript and PDF files exist, including GSview, ghostview, gv, ggv, and kghostview. This is far from a comprehensive list.
PySol is an exciting collection of more than 200 solitaire card games. Its features include a very nice look and feel, multiple cardsets and table backgrounds, unlimited undo/redo, loading/saving games, player statistics and log files, a hint system, demo games, support for user-written plugins, sound support (including samples and background music), an integrated HTML help browser, and lots of documentation.
zlib is designed to be a free, general-purpose, legally unencumbered, lossless data-compression library for use on virtually any computer hardware and operating system. The zlib data format is itself portable across platforms. Unlike the LZW compression method used in Unix compress(1), the compression method currently used in zlib essentially never expands the data. (LZW can double or triple the file size in extreme cases.) zlib's memory footprint is also independent of the input data and can be reduced, if necessary, at some cost in compression.
FFTW is a fast C FFT library. It includes complex, real, symmetric, multidimensional, and parallel transforms, and can handle arbitrary array sizes efficiently.It is typically faster than other freely available FFT implementations, and is even competitive with vendor-tuned libraries (benchmarks are available at the homepage). To achieve this performance, it uses novel code generation and runtime self optimization techniques (along with many other tricks).
