Cowbell: Cowbell is tightly integrated with Amazon.com using its free SOAP service. Cowbell employs this service not only to fetch album cover images, as most tag editors do, but also in combination with intelligent algorithms to "guess" the appropriate song information from song titles. It can also cache these cover images in the same directory where that album resides. Going above and beyond the call of tagging, Cowbell also can rename your files based upon a user-configurable pattern (More detail on how to use this feature is covered in the Advanced Guide) and also export a M3U/PLS playlist of your songs in album-order. For you console junkies, Cowbell also offers a command-line based batch tagger which can tag and "guess" a whole collection of music with just a few keystrokes. And, to top it all off, Cowbell is fully internationalized and has been translated into German, French, Portuguese, Spanish, Norwegian and Swedish.

In addition to the recipes, it allows multiple brewers to privately track their own batches, emailing them on racking, bottling, and lagering dates. Finally, it has a 'taster's review' section which allows those who try your brew to rate and comment on the batch. This information goes into the overall recipe ranking.

Cymbaline: 'Cymbaline' is an intelligent learning (weighted playlists) music player. It sets a score for each track based on your listening habits, and you can set thresholds to create playlists with your favorite tracks automagically. It is particularly useful if you have a large playlist which you don't want to micromanage, if you want to listen to music in the background) perhaps with random selections that you like), or if you have a collection of albums, not singles. In random mode, it will play your favorite tracks more often. 'Cymbaline' also allows album-based navigation: you can start playing the next album, skip 2 albums ahead, go to a specific album, etc. There is also a random queue mode where you see a list of randomly chosen tracks that play consecutively.

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.

DVC for Emacs: This is a candidate for deletion: Links broken. No links to page. No response to email to maintainer. Poppy-one (talk) 11:17, 31 July 2018 (EDT) DVC is a common Emacs front-end for a number of distributed version control systems. It currently supports GNU Arch, Bazaar, git, Mercurial, and Monotone.

This package was written by a trumpet player, who needed to tune lots of different notes on the fly. Many of the free packages out there are "guitar" tuners that must first be told which few notes you are trying to tune.

Dap: 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.

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.

DataCaptureTool: This is a candidate for deletion: All links broken. Software not on archive.org. Email to maintainer broken. poppy-one (talk) 02:37, 28 July 2018 (EDT) DataCapture was born out of frustration, and after much procrastination. Every time I had to get numerical values of a graph from a journal or a conference paper, I had to painstakingly approximate data points from the graph as best I could. Every time the points would come out inaccurate and a rather poor reproduction of the actual data. I wanted to write a program that would automate this task, and do a much better job at that. But then, that was three years ago. Finally its done. Its not the best thing that I have created, but certainly, one of the most useful. Its written in TCl/Tk and is a very small and uncomplicated aplication. Something that you can easily incorporate into your own applications easily.

Drivel: Drivel is a LiveJournal client for the GNOME desktop. It is compatible with the new features of GNOME 2.0 including GConf and GTK 2.0.

Druid: Druid lets users create databases graphically. Users can add/modify/delete database objects (fields, tables, etc.) using a simple GUI and can document each table and field with HTML information. Druid then generates an SQL script with all table definitions that can be piped to the DBMS; a data dictionary file containing all the tables and field in the database, and Java classes that contain both the tables' constants and users' code. The program works with Java, C, and C++. There is a plug-in architecture, so users can write their own modules. The latest features let you examine the entire jdbc DB structure, rebuild the jdbc DB on the fly using the druid's current database, import the jdbc DB structure into druid for reverse engineering, and add/modify/delete tables' records using a simple grid control.

Dunst: Dunst is a minimalistic notification daemon for X and Wayland. By default, it only displays a colored box with unformatted text. It can be extensively customized by modifying its config file.

Enblend blends away these seams using a multiresolution spline. 'Enblend' blends different image features across a transition zone proportional to the spatial frequency of the features. Big, smooth objects (sky, clouds) have low spatial frequency and should be blended across a very wide region (we expect the sky to be uniform in appearance, so sudden color changes are very noticeable). Images with high spatial frequency (trees, windowpanes) have sudden changes from light to dark. We expect to see color changes here; if you blend over a wide area there is the possibility of noticeable ghosting. So high-frequency components are blended across a narrow transition zone.

Professional and Educational usages The FlightGear project has been used in a range of projects in research and industry, including by NASA for both Earth and Mars conditions (e.g. in ARES glider design for Mars^[1]. It has been used as a research and development platform by various agencies and universities. Other than aerospace research and development, FlightGear is used in aviation or aviation-adjacent industries in various ways. For example, teaching student pilots procedures or handling in a simulator saving expensive flight time - e.g. FlightGear is integrated into various FAA certified training simulators^[2], in contrast to use in full-motion (6-DoF) research simulators like at the University of Naples^[3] where FlightGear is utilised for physics not just used for visualisation/interface. Similarly, FlightGear has been used to teach air traffic controllers (ATC)^[4] and allows for dedicated ATC client/instructor interfaces as well as visuals using real-life ATC tools like binoculars or cameras - teachers can alter traffic, weather, re-create traffic patterns, and so on. Different forms of instructor stations are possible for different areas of instruction. FlightGear has also been used in general education e.g. exhibits in museums^[5] and all sorts of DiY projects. About the project The simulator is created by an international group of volunteers, and released as free, open-source GPL software. The goal of the FlightGear project is to create a sophisticated and open flight simulator framework for use in research or academic environments, pilot training, as an industry engineering tool, for DIY-ers to pursue their favorite interesting flight simulation idea, and last but certainly not least as a fun, realistic, and challenging desktop flight simulator. Being free software, FlightGear has historically received development from the science and engineering community. Many contributors have had an academic background in engineering, maths, physics, or computer-science - in addition to some involvement or interest in aviation like being pilots (hobby, professional, test pilots, or retired). This is true especially among long-term contributors, and the academic insight has shaped the project's simulation standards.^[6] There are many exciting possibilities for an open, free flight sim. It is hoped that this project will be interesting and useful to many people in many areas. History FlightGear started as an online proposal in 1996 by David Murr, living in the United States. He was dissatisfied with proprietary, available, simulators citing motivations of companies not aligning with the simulators' users, and proposed a new flight simulator developed by volunteers over the Internet.^[7] Development of an OpenGL based version was spearheaded by Curtis Olson starting in 1997. FlightGear incorporated other open-source resources, including the LaRCsim flight dynamics engine from NASA, and freely available elevation data. The first working binaries using OpenGL came out in 1997. By 1999 FlightGear had replaced LaRCsim with JSBSim built to the sims' needs, and in 2015 NASA used JSBSim alongside 6 other space industry standards to create a measuring stick to judge future space industry simulation code. The FlightGear project has been nominated by SourceForge, and subsequently chosen as project of the month by the community, in 2015, 2017, and 2019.^[8] ^[9] ^[10]

Flounder: 'Flounder' visualizes 4D data (x,y,z,t). It can produce isosurfaces, 3D surface and solid renderings, as well as 2D slices. Several data sets can be viewed simultaneously. Temporal data at a spatial location can be examined with output in several formats including PNG and GIF animations.

Flowblade: Flowblade Movie Editor is designed to provide a fast, precise and as-simple-as-possible editing experience.
