Calcurse: Calcurse is a text-based personal organizer which helps keep track of events and everyday tasks. It has a calendar and a "todo" list, and puts your appointments in order. The user interface is configurable, and you can choose between different color schemes and layouts. All of the commands are documented within an online help system.

Calendar Lock PEA: Calendar Lock PEA is a program for encrypted management of appointments and tasks with cloud connection to Nextcloud and some other cloud providers.

Calendula: Today's cash-strapped nonprofit organizations (NPOs) need as much help as they can get in their fundraising efforts. Most nonprofits rely heavily on fundraising software systems to manage their donors and prospective donors. The Calendula project was created to offer nonprofits a Free Software alternative to the mostly proprietary fundraising/contact management systems that dominate the field. The Calendula project is still in the planning stage; a requirements document and other background information are available through CVS.

CardDavMATE: CardDavMATE is 100% JavaScript+jQuery CardDAV web client/application. Main features: asynchronous background synchronization, support for RFC compliant vCards (version 3.0), support for delegated addressbooks, customizable contact displaying and sorting, localization support (15 languages) and clean user interface.

Ccaudio: GNU ccAudio is a stand-alone C++ class library and newly designated GNU package for manipulating audio data, whether on disk or in memory. GNU ccAudio offers the ability to work with audio file formats on disk by treating audio data as sequenced arrays of sample data rather than as arbitrary octets as some audio file manipulation libraries do. In addition to being audio content aware, GNU ccAudio allows header manipulation for setting things like annotation fields. GNU ccAudio is also endian aware and highly portable to both posix and win32 based systems. GNU ccAudio also offers basic audio signal processing including tone data set generation and pluggable codec operations. In the future we will provide loadable free software audio codec modules for many common audio encoding formats where not patent encumbered.

Ccrtp: GNU ccRTP is a high performance threadsafe C++ RTP (Real-Time Transport Protocol) stack. It can be used to build both client and server applications for audio and visual conferencing over the Internet, for streaming of realtime data, and for next generation IP based telephony systems.

Ccscript: GNU ccScript is a C++ class framework for creating a virtual machine execution system for use with and as a scripting/assembler language for state-transition driven realtime systems. It is the core of the scripting engine found in GNU Bayonne. It is meant to be used where step execution is important, and where each step is in response to a callback event or a state machine transition. It offers deterministic execution and low overhead so that many concurrent instances can run together. However, in addition to offering step machine execution, GNU ccScript loads all scripts into an active image at once. This is for performance, as all operations in the script system, to assure deterministic execution, are in memory. GNU ccScript also offers the ability to load new scripts en masse. Existing active sessions operate on the currently loaded scripts, and new sessions are offered the new script. When the last active session on an old script set completes, the entire script set is flushed from memory, so you can operate scripted servers without downtime for rebuilding script images in memory.

Cday-php: The CDAY Calendar Almanac displays historical anniversaries such as birthdays and general events. It displays the equivalent date in multiple calendar systems, including Hebrew, Julian, JDNs, Great Underground Empire (Zork), and Shire (Lord of the Rings). Separate command line and Web-based versions are available, along with a free library of thousands of events.

Celebrat: Celebrat is a very easy-to-use, non-interactive, text-mode calendar application. It reads a data file in ASCII format, and prints on stdout a human-language summary of what events will take place up to ten days from now. It also includes a small daemon which announces events that are due by putting a message on every registered terminal, or by integrating the announcement in the bottom line of GNU screen sessions.

Chart: Chart is stock market charting program. It downloads and displays market daily data and current price quotes in various styles and with many standard technical analysis indicators and averages. Data is obtained from several sources, including Barchart and Yahoo Finance (which covers most major world exchanges). Alert levels, notes, and free-form trend lines can be added to charts. Chart is at "personal project" level, which means the features are those things which interest the author, but the aims are serious. Chart is written in GNU Guile and perl, and customizations and extensions can be added using Scheme code. The main interface is the Guile Gtk GUI. An Emacs interface is included too, for viewing price quotes within Emacs, including importing into the Simple Emacs Spreadsheet (and other uses).

ChkBk: ChkBk is a simple, yet functional checkbook registry program. It allows the user to keep an accurate record of checking and/or savings account transactions, to view a full or partial transaction history, to backup and restore the database from a file, and to print a list of transactions in a nice, easy-to-read format.

Chronos: Chronos is a Web agenda calendar for intranets, (although it can be used from anywhere). It can send reminders by email, and lets you to schedule multi-user events. It is fast and light on resources. The balance between size and speed can be tweaked by tweaking mod_perl and Apache.

ClosedShop: 'closedShop' attempts to provide an easy to set up, manage and utilize shopping cart. Based on Perl and MySQL, its aim will be to provide all the features a commercial shopping cart offers at no cost. Users can search for items by description, title, or category, and they can have individual accounts for checking order status. The package has a cookie based shopping cart, so customers can continue shopping. It also has email confirmations for both customer and administrator, as well as the ability to manage a mailing list of customers. It has a relatively secure user/admin authentication without a secure server -- with a secure server (for which there is support), you would be very secure.

ConTagged: ConTagged is a Web-based address book for small companies. It features a public address book which is writable for all company staff and a personal address book for each staff member. Contacts can be grouped and looked up flexibly by assigning tags to them. It requires an existing LDAP server to authenticate users and to store the contact data.

Confy: Confy is a program that lets users navigate conference schedules. Events can be listed by day, room or track, and users can see the events' descriptions and other information. Talks can be marked as 'starred' for ease of identifying them at a later time. Confy automatically checks for updates to schedules, which can be added to Confy in a number of formats. Confy uses GTK and libhandy for its graphical user interface, allowing it to be used on a variety of screen sizes.

The architecture of the DEWAWI is based on modules and it is easily expandable to new functions.

DMBCS Market Data API: While there are several open APIs available on the Internet for fetching stock market trading data, there are scant few which provide data of the markets themselves, in particular it is quite difficult to programmatically get an enumeration of all the components of a particular market from the Internet. The DMBCS Market Data service provides this facility, offering two end-points which enumerate all markets known to the system and all components of any given market. The service provides a RESTful API which is currently freely available without registration. More information can be found at https://rdmp.org/trader-desk. Here we present the reference implementation of a client-side library for programmatically getting data from the service.

DMBCS Trader Desk: Lightning fast application for interactively exploring historical stock market prices.

DTemplate: dTemplate is a flexible template system. It can generate HTML or newsletters, etc., and is similar to the CGI::FastTemplate system in that it separates the code from the design. You can define only one kind of template variable (placeholder), but you can assign anything you want to it, even an unnamed subroutine, which can parse other templates. You can define a template parse tree this way. Advanced features include printf formatting of template variables (for statistic generation), transparent handling of multiple styles of a template (for multi-language sites or skinned web-pages), and encoders (uri_encoder and html_encoder). You can write template-parsing routines in the same way the templates are structured logically: starting from the biggest and going to the smallest.

Dartool: This is a candidate for deletion: broken links, can't find software elsewhere, software not on archive.org, my email to developer was unanswered. Danm (talk) 12:06, 30 December 2017 (EST) Recruiters reposting the same positions every day on DICE. This makes the time period selection on the site nearly worthless, and forces job seekers to weed through all of the posts they've already seen. 'dartool' circumvents this by building a cache of previously seen posts and creating a local Web page each time it is run that only lists positions not previously seen.

Darwin2k: 'Darwin2k' is a robotics design and simulation program. Its simulation capabilities support engineering design and controller prototyping for robotic application; for example, it includes detailed motor and gearhead performance models, and the ability to estimate stresses in structural elements during simulation. Darwin2K is *not* an end-user application. Most uses will require at least a little coding, usually to specify application-specific robot controllers and models, high-level task descriptions, or specialized simulation components. That being said, Darwin2K does include a range of general-purpose robot models, controllers, and simulation and analysis capabilities, useful in a wide range of robot design and programming applications, that eliminate most of the work in developing a task-specific simulation or optimized robot prototype. The system also includes a distributed evolutionary algorithm for automated synthesis and optimization.

DataMelt: DataMelt (DMelt) is an environment for numeric computation, statistical analysis, data mining, and graphical data visualization on the Java platform. This Java multiplatform program is integrated with a number of scripting languages: Jython (Python), Groovy, JRuby, BeanShell.

Dia: 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.

DialFOX: This is a candidate for deletion: 1. No files sources found. DialFOX is an express dialplan report generator that is used with the Asterisk PBX system. It is able to make an inventory of any device (such as SIP phones, softphones, and ATA) that is active in a local network. It lists their extensions, IP address, username, caller queue, device info, and comments. It can easily access with a mouse click to any SIP device that is found in the LAN. Furthermore, DialFOX provides additional information about phone devices like firmware release, key functions, and many more. DialFOX replace each sheet that are maintained by hand like hosts file and attaining this unnecessary.

Dismal: Dismal (Dis' Mode Ain't Lotus) is a major mode for GNU Emacs that implements a spreadsheet. It is designed to be keystroke driven rather than mouse/menu driven (although it can be menu driven), and it is extensible. Users can write their own commands and functions, for example, to allow a function cell to write to several nearby cells. A ruler can be put up that reflects the semantics of column names past the ones automatically provided as letters. Dismal has some useful functions that implement the keystroke level model of Card, Moran, and Newell. Dismal is now maintained within ELPA, https://elpa.gnu.org.

Dlume: Dlume is nice, gtk2-based addressbook. You can easily add, edit and delete records to/from database (but Dlume doesn't rely on an outside database - It stores your contacts in XML format). The Quick-search feature allows you find required entry in comfortable way. Export to CSV and HTML formats is also available.

Dmbcs-kraken-api: Kraken is a virtual currency exchange, which also handles fiat (real) currency amounts. Subscribers to the service have an account with associated funds attached. The web site (www.kraken.com) provides the user with an account overview (i.e. current balance), currency-pair exchange market status (history of prices and current order book), and the means to place entries on the order book; bids for a currency which can be immediately met with orders to sell the currency are automatically transacted, with the Kraken site taking a small and variable cut of the deal. Kraken also provide a stateless, web-based API by which all of the above actions can be undertaken programmatically. This is fully open, and described at the Kraken exchange web site. The DMBCS client-side C++ library implements all features of the API in a fully encapsulated C++ class, allowing users to implement algorithmic or robotic trading and dynamic exchange modelling.

Dnote: A simple a command line note-taking software that supports multi-device sync and a web interface. It is popular for building a personal knowledge base for its simplicity.

DocMGR: DOCMGR is a full-featured document management system that incorporates automatic indexing of uploaded files, automatic ocr and content indexing of pictures, group-level permissions, WebDAV, and a discussion board for stored files. Beyond its stock indexing subsystem, DocMGR also has the capability to incorporate Tsearch2 (a full-text indexing add-on for Postgresql) for a responsive, full-text file indexing system.

Docassemble: docassemble is a system for guided interviews and document assembly. It provides a web application that conducts interviews with users. After each interview, docassemble generates documents in various formats based on user input and preconfigured templates. Though the name emphasizes the document assembly feature, docassemble interviews do not need to assemble a document; they might submit an application, direct the user to other resources on the internet, store user input, interact with APIs, or simply provide the user with information. docassemble was created by a lawyer/computer programmer for purposes of automating the practice of law, but it is a general-purpose platform that can find applications in a variety of fields.

Doxia can be used to generate static sites in addition to being incorporated into dynamic content generation systems like blogs, wikis and content management systems. Doxia is used exensively by Maven and it powers the entire documentation system of Maven. It gives Maven the ability to take any document that Doxia supports and output it any format. It became a sub-project of Maven early in 2006.

Duty Roaster

Duty Roaster is a program for managing and generating duty rotas. Some of its features are:

The programs component for calculating overtimes was redesigned from scratch and has been completely rewritten. As a consequence, the program now handles two different overtime classes (normal overtime and on public holidays)
User defined overtimes which can be applied manually to any entry in the shift table
It is now possible to edit payed durations and/or add custom overtimes for already assigned shifts. Besides, every entry in the workers schedules may store an additional comment.
Extraordinary shifts may have a negative payed duration.
ttlements may be exported to html.
The program now is able to record and store changes made to rotas. These changes will be visible in the settlements which can be exported.

E-GADS: E-GADS! (Electronic Ground Search and rescue Administrative Database System) is a Web-based database that lets ground search and rescue teams track membership, certifications, search reports, events, and training records. It is in both English and French.
