The General Image Manipulation Program - GIMP
This is considered to be a very powerful graphics manipulation system, somewhat competitive with Adobe's "PhotoShop" product. (There are arguments over which program is actually superior. If people have hope of considering GIMP competitive, then it must be at least pretty good...)
An X-based document editor that creates LaTeX output.
xearth renders the Earth onscreen along with the appropriate lighting for the time of day. Many things are configurable, including:
What projection is used (Mercator or an orthographic (pseudo-3D) view);
Use of gridlines
What cities are labelled
What point of view is used (by default, you look down from the Sun)
Freedom-of-Choice CAD Commercial CAD for Linux/Solaris
Software Forge used to regularly spamming Linux newsgroups on Usenet, which forces me to recommend not buying their product. Even if it was good software (and all reviews thus far indicate that it is not), Software Forge has been acting as poor a Usenet "citizen" and is thus deserving of not selling product.
LinuxCAD / Freedom-of-Choice CAD Impressions (As published in Linux Gazette)
A user has bought Software Forge's package, and reports that the software may not live up to its advertising. Not a big surprise...
LinuxCAD Response to Review - also in Linux Gazette
Software Forge responds to the review, presenting their typical none-too-well-proofed sales pitch, along with the claim that Wuest's review was "fraudulent." (But also that the things that were wrong have been fixed, so it's no longer true... So did the review lie, or do they have a completely different definition of the word "fraudulent" than the rest of us?)
FREEdraft - 2D Mechanical CAD System
Pretty dead...
Rosegarden is a free integrated musical notation editor and MIDI sequencer for Unix/X platforms, with specific support for Linux PCs and SGI IRIX workstations. Binaries for these machines are available by ftp, together with (we hope) fairly portable sources.
Site with a wide variety of software and data for the Persistence Of Vision raytracing system.
MagicPoint - X11-based presentation tool
Doesn't import in any external formats; it can export to HTML and LaTeX formats...
A "libre" version of the game of Civilization.
ImPress - WYSIWYG Layout Tool written using TCL/Tk.
This is a package that uses OpenGL to do "nifty renderings" of slides and slide transitions; it works with PDF files or graphical images.
GraphViz - the Graph Visualization Project. See also GraphViz at ATT
OpenDX Home Page - visualization package that uses Lesstif.
xscript is a more-or-less working record/playback facility.
AccessX - Tools to make X more usable to people with certain disabilities
MPlayer is a movie player for various Linux-like operating systems. It plays movie files that come in a fairly wide variety of commonly-used formats, and supports most interesting output methods.
For better or for worse, MPlayer cannot presently be distributed in binary form, for two reasons falling into two fundamental areas:
Technical
Many bits of MPlayer require local compilation in order that the program may know what sorts of optimizations may be used, locally. It uses Intel MMX and various other similar "DSP-like" processing features (e.g. AMD 3DNow!) which differ substantially between different CPU versions.
This is a fairly unusual thing. Many, many classes of programs are I/O or user-input bound, so that throwing in CPU-specific optimizations will provide little or no perceptible improvements in performance.
The heavy burden video decoding processing of MPlayer means that it is one of the applications that can significantly benefit from this sort of tuning.
A "generic" version of MPlayer would be fairly likely to be many times slower than one attuned to the optimizations available on your platform.
Licensing
MPlayer has components that are licensed under substantially different and incompatible licenses.
Its own code is redistributable, but the compilation of its code with other libraries and third party CODECs is not redistributable in binary form. The fun of "dueling licenses" (not all for free software ).
Kodi (often still called XBMC).
Kodi is a "media player" system, which deals with music, videos, pictures, and other such stuff.
It is rife with extensions...
Cataloguing extensions, to draw in metadata about TV shows, movies, and music
Such as pulling episode information about TV shows,
Cover art for music albums,
Lyrics,
Fan art about TV series'
Video apps so you may play YouTube material on the big screen
"Skins" to allow customizing the user interface to... Someone's taste...
Animations so that cool stuff appears on screen as your cool music plays
Apps to pull weather forecasts
Apps to pull podcasts or videocasts from various sources
Upcoming schedules for the TV shows you have
Lots more
