X-Hive/DB is a powerful native XML database designed for software developers who require advanced XML data processing and storage functionality within their applications. The comprehensive X-Hive/DB Java API contains methods for storing, querying, retrieving, transforming, and publishing XML data. X-Hive/DB supports all major W3C standards, such as XQuery, XPath, DOM, XPointer, XML Schemas, and more.
GPLIGC is a program for analyzing IGC flight data from GNSS flight data recorders used by glider pilots. It uses Perl/Tk and gnuplot. The openGLIGCexplorer (written in C++) allows one to view the data in 3D with OpenGL, and can also be used as a digital elevation model terrain viewer. It can also be used for off-screen rendering of 2D and 3D images of flight tracks or terrain/map data.
smake is a highly portable 'make' program that makes commands up to date based on rules in Makefiles and on the timestamps of the related files. It implements a complete superset of the features of the classical POSIX/Unix make program. It warns about typical misuse of dynamic macros that prevent portability of makefiles. Its automake features allow you to run scripts to automatically create rules for unknown platforms.
Tulip is an information visualization framework dedicated to the analysis and visualization of relational data. Tulip aims to provide the developer with a complete library, supporting the design of interactive information visualization applications for relational data that can be tailored to the problems being faced. Written in C++, the framework enables the development of algorithms, visual encodings, interaction techniques, data models, and domain-specific visualizations. One of the goals of Tulip is to facilitate the reuse of components, and it allows developers to focus on programming their application. This development pipeline makes the framework efficient for research prototyping as well as the development of end-user applications. The framework also provides a complete software for visual analysis of relational data having attributes.
SATGUI is a framework for developing simple GUI client/Unix server applications. It uses a simple, easy-to-learn screen layout language (SAT/DL). The backend applications can be developed in almost any character-based language (shell script/Perl/AWK/C/etc.), and a basic interface to MySQL databases (SATMYSQL) is also available.
sdd is a replacement for a program called 'dd'. sdd is much faster than dd in cases where input block size (ibs) is not equal to the output block size (obs). Statistics are more easily understood than those from 'dd'. Timing available, -time option will print transfer speed Timing & Statistics available at any time with SIGQUIT (^\) Can seek on input and output Fast null input Fast null output. Support for the RMT (Remote Tape Server) protocol makes remote I/O fast and easy.
p is a pager like more or less. It is more conservative with screen handling and thus does not screw up the screen as easily as more or less. p uses its own termcap package with TERMPATH support that makes it easy to have a local .termcap file in the user's home directory to override bad termcap entries. p supports three text attributes for nroff: bold, italic, and bold-italic. p is able to find patterns in higlighted text, unlike more or less. p also filters out unprintable characters.
Makefiles is a high-level build system and suite of portability tools. It is meant to be easier to use than autoconf and generally superior. The package contains a set of rules that allows you to compile structured projects with small and uniformly structured makefiles. All rules are located in a central directory. Compiling the projects on different platforms can be done simultaneously without having to modify any of the makefiles that are located in the projects directories.
compare is similar to cmp but faster and with better readable output. compare examines one file and standard in, or two files on a byte by byte basis, and prints the file position of the first difference it finds, first in decimal and then in hexadecimal, followed by the differing byte content in hexadecimal and a quoted character.
netscript is a portable/multi-platform, lightweight TCP/UDP socket scripting system. It is intended to automate situations, built on a word-to-word ruleset response system. It includes wildcard support, character replacement, random replacement, argument inclusion, server timeout, initial send, display altering, multiple character dump formats, telnet protocol support, logging, program to socket dumping, executable ruleset support, reverse binding, module support, data truncation, data formatting, permission options, virtual hosting support, history storage, dynamic storage variables, directory placement, character omitting, timed rules, background support, syslog support, routing support, socket options, interactive mode, and graphical user interface support.
