Technically speaking, it is a plugin for the computational tool wasora, which provides means to parse and understand a high-level plain-text input file containing algebraic expressions, data for function interpolation, differential equations and output instructions amongst other facilities. Therefore, any mathematical computation which can be done by wasora—i.e. solving systems of differential-algebraic equations, multidimensional interpolation of scattered data, numerical integration and differentiation, etc.—can be combined with the facilities that besssugo provides to create visual representations in the form of animations.
Bfloop
bfloop is an interpreter for the BLooP and FLooP programming languages described in the book Gödel, Escher, Bach by Douglas Hofstadter. BLooP is a language that has only bounded loops, in other words before you enter a loop you have to give a fixed upper limit on the number of times to run the body, and you can’t change the limit while in the loop. It is impossible for a BLooP program to run forever; it always quits with an output in some finite time, an upper limit for which is predictable in advance. Functions that BLooP can compute are called primitive recursive functions, and it turns out that not all functions are primitive recursive. The FLooP language is the same as BLooP with the addition of an unbounded loop (MU-LOOP). FLooP can calculate anything your computer can calculate, but you cannot say in general whether a FLooP program will eventually terminate.

It runs on most GNU and Unix systems (GNU/Linux, GNU/Hurd, FreeBSD, NetBSD, OpenBSD, Solaris, Tru64, HP-UX, BeOS, IRIX, AIX, Mac OS X and others) and on other systems and needs only 4 MB of RAM. The user interface comes in English, German, French, Spanish, Dutch, Russian and Danish, and can be changed during run time. GNU CLISP includes an interpreter, a compiler, a debugger, CLOS, MOP, a foreign language interface, a socket interface, i18n, fast bignums, arbitrary precision floats and more. An X11 interface is available through CLX, Garnet, CLUE/CLIO. GNU CLISP runs Maxima, ACL2 and many other Common Lisp packages.
Cloudgizer
Cloudgizer is a tool for building web applications as Apache modules in C language enhanced with simple markup, with emphasis on performance, small-footprint, and more productive and safer programming in C. It combines the ease of scripting with the power of C, improving the resource utilization for cloud applications. The programmer writes simple markup language mixed with C code, which is then translated entirely into C code and compiled natively as Apache module. The resulting application is fast and takes less memory, as there are no interpreters or virtual machines. Features include easy markups to use MariaDB database, HTML input parameters, cookies, simpler outputting of web pages, files storage and manipulation, encryption, encoding, program execution, web calls, safer and easier string manipulation etc. - the list is too long to place in one sentence. Overall Cloudgizer does a lot of stuff for you that you'd otherwise need to do yourself. A memory garbage collection system and memory overwrite/underwrite detection comes in handy for program stability. The same goes for string and memory handling markups to help write applications that won't crash. Also included is an application packaging system and an automated application installer. This makes rollout of products and release cycle more manageable. Cloudgizer source files have extension .v. Cloudgizer pre-compiler (cld program) will turn your .v files into .c files, ready for compilation as pure C programs. Then, your program will be compiled and linked with Apache web server on RH/Centos systems. It links with Apache as an Apache module in a "prefork" configuration. It does the work of communicating with Apache, and it makes it easier to write high-performance/small-footprint web programs in C. Cloudgizer is not designed to be thread-safe as it works in a "prefork" configuration of Apache. You can also build command-line programs. The same program can serve as both command-line utility and a web program linked with Apache. Cloudgizer works with RedHat/Centos 7 operating system, Apache web server and mariaDB database.

Additional features include hierarchy handling, a Guile module adapted from the Emacs calendar for performing date arithmetic, and outer joins on either or both sides of a match.
Compare
'Compare' is similar to cmp (in the 'diffutils' package) but faster and with better readable output. It 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.
Complexity Heckert gnu.tiny.png
Complexity may be used to analyze the degree of complexity of functions in a C program. It estimates the difficulty that a human might have in understanding or testing the code. This software attempts to integrate more information than other, similar programs, in order to derive a more accurate estimate of complexity.
Coreutils Heckert gnu.tiny.png

Cpio Heckert gnu.tiny.png
Cpio copies files into or out of a cpio or tar archive. The archive can be another file on the disk, a magnetic tape, or a pipe. GNU cpio supports the following archive formats: binary, old ASCII, new ASCII, crc, HPUX binary, HPUX old ASCII, old tar, and POSIX.1 tar. The tar format is provided for compatibility with the tar program. By default, cpio creates binary format archives for compatibility with older cpio programs. When extracting from archives, cpio automatically recognizes which kind of archive it is reading and can read archives created on machines with a different byte-order.
Cppi Heckert gnu.tiny.png
GNU cppi is a cpp directive indenter. It indents C preprocessor directives to reflect their nesting, among other regularizations.
Cuba
The Cuba library offers a choice of four independent routines for multidimensional numerical integration: Vegas, Suave, Divonne, and Cuhre. They work by very different methods, first three are Monte Carlo based. All four have a C/C++, Fortran interface and can integrate vector integrands. Their invocation is very similar, so it is easy to substitute one method by another for cross-checking. For further safeguarding, the output is supplemented by a chi-square probability which quantifies the reliability of the error estimate. This package provides the shared libraries required to run programs compiled with Cuba. To compile your own programs you also need to install libuba3-dev.

Curse of War
Curse of War is a fast-paced action strategy game for GNU/Linux implemented using C and ncurses. Since version 1.2.0, there is also an SDL version. Unlike most RTS, you are not controlling units, but focus on high-level strategic planning: Building infrastructure, securing resources, and moving your armies. The core game mechanics turns out to be quite close to WWI-WWII type of warfare, however, there is no explicit reference to any historical period.
DBG-Server
'DBG' is a PHP debugger and profiler. It's can backtrace errors. It shows local and global variables as well as parameters which have been passed to all nested function calls at any point of execution. It also lets you execute scripts in a step-by-step manner, set breakpoints (including conditional ones), evaluate expressions, and watch variables. The profiler lets you find bottlenecks in PHP code at the functions level, the modules level, and even the source lines level.
DNSleak
DNSleak inspects DNS packets on the local network interface to detect leaks. Unlike web-based solutions, it works at the local computer level. No third party servers are used and DNS leak result is a true/false response.
DSSI
DSSI is an API for audio plugins, with particular application for software synthesis plugins with native user interfaces. DSSI is an open specification developed for use in Linux audio applications, although it is portable to other platforms. It may be thought of as LADSPA-for-instruments, or something comparable to VSTi. This package contains the header file required for compiling hosts and plugins.

Dap Heckert gnu.tiny.png
Dap is a small statistics and graphics package, based on C, that provides core methods of data management, analysis, and graphics commonly used in statistical consulting practice. Anyone familiar with basic C syntax can learn Dap quickly and easily from the manual and the examples in it. Advanced features of C are not necessary, although they are available. As of Version 3.0, Dap can read SBS programs, thereby freeing the user from having to learn any C at all to run straightforward analyses. The manual contains a brief introduction to the C syntax needed for C-style programming for Dap. Because Dap processes files one line at a time, rather than reading entire files into memory, it can be, and has been, used on data sets that have very many lines and/or very many variables.
Datamash Heckert gnu.tiny.png
Datamash is a command-line program which performs basic numeric, textual and statistical operations on input textual data files. it is designed to be portable and reliable, and aid researchers to easily automate analysis pipelines, without writing code or even short scripts.

Denemo Heckert gnu.tiny.png
Denemo is a music notation editor that provides a convenient interface to the powerful music engraving program Lilypond. Music can be typed in using the computer keyboard, played in using a MIDI keyboard, or even input via a microphone connected to the sound card. Denemo itself does not engrave the music - it uses LilyPond which generates beautiful sheet music to the highest publishing standards. The final product is publication-quality music notation that is continuously generated in the background.
Devhelp

Dia Heckert gnu.tiny.png
Dia is a program for creating diagrams of all kinds. It can create many types of diagrams, including UML, network and flowchart diagrams. The engine is very flexible and dynamically loads diagram-types from disk. Dia can also print diagrams and export tham to a number pf formats including EPS, SVG and PNG.
DiaSCE
DiaSCE is a C/C++ code editor for GNOME. It pretends to be a complement to Glade, so it doesn't include an environment for GUI development. It has neither a debugger or other kind of tool to help debugging. The idea is for it to be a light code editor that doesn't need too many resources, and makes use of external tools (gcc, glade, ddd, etc.) for some tasks. This project was formerly known as 'david.'
Dico Heckert gnu.tiny.png
Dico is a flexible modular implementation of DICT server (RFC 2229). In contrast to another existing servers, it does not depend on particular database format, instead it handles database accesses using loadable modules. The package includes several loadable modules for interfacing with various database formats, among them a module for dict.org databases and a module for transparently accessing WordNet. New modules may be written in Guile or Python. A console client program, dico, is also included.
Diction Heckert gnu.tiny.png
This program includes both 'diction' and 'style'. 'Diction' identifies wordy and commonly misused phrases; 'style' analyzes surface characteristics of a document, including sentence length and other readability measures. While these programs cannot help you structure a document well, they can help to avoid poor wording and compare the readability of your document with others. Both commands support English and German documents.
Diffutils Heckert gnu.tiny.png
A group of utilities that displays difference between and among text files. 'diff' outputs the difference between two files in any of several formats. If the files are identical, it normally produces no ouput; if they are binary (non-text) it normally reports only that they are different. 'cmp' shows the offsets and files numbers where two files differ; it can also show, side by side, all the characters that differ between the two files. 'sdiff' merges two files interactively. 'diff3' shows differences among three files. If two people have made independent changes to a common original, diff3 reports that difference between the original and the two changed versions, and can produce a merged file that contains both persons' changes along with warnings about conflicts.
Dionysus Heckert gnu.tiny.png
Dionysus is a convenient system for quickly retrieving the values of mathematical constants used in science and engineering. Values can be searched using a simple command-line tool, choosing from three databases: universal constants, atomic numbers, and constants related to semiconductors.
DirectFB
'DirectFB' is a thin library that provides developers with hardware graphics acceleration, input device handling and abstraction, an integrated windowing system with support for translucent windows and multiple display layers on top of the framebuffer device. It is a complete hardware abstraction layer with software fallbacks for every graphics operation that is not supported by the underlying hardware.
Direvent Heckert gnu.tiny.png
Direvent is a program that monitors a set of directories on the file system and reacts when their content changes. When a change is detected, the daemon reacts by invoking an external command configured for that kind of change.
Dnsmasq
Dnsmasq is a lightweight DNS forwarder and DHCP server. It is designed to provide DNS and optionally, DHCP, to a small network. It can serve the names of local machines which are not in the global DNS. The DHCP server integrates with the DNS server and allows machines with DHCP-allocated addresses to appear in the DNS with names configured either in each host or in a central configuration file. Dnsmasq supports static and dynamic DHCP leases and BOOTP/TFTP for network booting of diskless machines.
Dominion Heckert gnu.tiny.png
Dominion is a multi-player world simulation and role-playing game. Each user controls a nation, making economic, political and military decisions for it.
Dont Hang
“Don’t Hang” is a simple hangman game for acquiring and consolidating a basic vocabulary in a foreign language. It supports loading custom word lists and works with Unicode and bidirectional text. It also supports pasting characters from the clipboard.
Doomsday Engine
Doomsday Engine aims to retain the original feel of the games yet leverage modern techniques and technologies, including hardware accelerated 3D graphics and client/server networking. A lot of emphasis is placed on good-looking graphics.
Dosfstools
The dosfstools package includes the mkdosfs (aka mkfs.dos and mkfs.vfat) and dosfsck (aka fsck.msdos and fsck.vfat) utilities, which respectively make and check MS-DOS FAT filesystems on hard drives or on floppies. This version uses the enhanced boot sector/superblock format of DOS 3.3+ as well as provides a default dummy boot sector code.
Duro
The goal of the Duro project is to create a library which is as compliant with the proposed database language D as it is possible for a C library. This library is supposed to serve as a basis for a truly relational database management system (TRDBMS).
  • Tuples and tables (relvars).
  • Relational algebra: RENAME, select (restrict), project, EXTEND, JOIN, SEMIJOIN, UNION, INTERSECT, MINUS, SEMIMINUS, SUMMARIZE PER, DIVIDEBY PER, WRAP, UNWRAP, GROUP, and UNGROUP.
  • Virtual tables (views).
  • Locking and nested transactions.
  • Duro tables are true sets -- uniqueness of tuples (rows) is always enforced. When creating real tables, at least one candidate key must be supplied. A candidate key may be empty.
  • User-defined types (including type constraints) and operators.
  • Declarative integrity.
  • Tcl interface, including support for relational expressions in Tutorial D syntax and operators implemented in Tcl ("stored procedures").
  • Simple GUI admin tool.
xs Duro is implemented on top of the Berkeley DB database library.
