crip is a terminal-based ripper/encoder/tagger tool for creating Ogg Vorbis/FLAC/MP3 files under UNIX/Linux.
It is well-suited for anyone (especially the perfectionist) who seeks to make a lot of files from CDs and have them all properly labeled and professional-quality with a minimum of hassle and yet still have flexibility and full control over everything.
Current versions of crip only support Ogg Vorbis and FLAC. If you want to make MP3 files go back to the past and use crip-1.0.
Main features:
- Track grouping for automated tagging and appropriate normalization/vorbisgain on multi-track pieces.
- CDDB fetching to populate default information.
- CDDB submit to update the CDDB database with your more accurate info.
- Automates as much of the tagging as possible for fully-labeled professional quality music files.
- Automatically trims digital silence at the beginning and end of a track/group (if desired).
- European character support. Also European character-mapping support.
- Flexibility and full user control in tagging and file naming.

RipIT is used to create MPEG-1 Layer 3 (mp3), Flac (flac) or Ogg Vorbis (ogg) audio files from an audio CD and from version 3.4 also faac (m4a). RipIT is a console based front-end (no fancy GUI here), written in perl, for these excellent programs:
- dagrab, cdparanoia or cdda2wav (tosha and cdd are also supported) for ripping the audio CD tracks (I dont know if dagrab is still up to date..., but its COOL!)
- Lame, OggVorbis, Flac or Faac for encoding the wav files to mp3, ogg, flac or m4a (find some info and links)
- CDDB_get (perl module) for CDDB retrieval (info and links).
Main features:
- Gets the Audio CD Album/Artist/Tracks information from CDDB
- Rips the Audio CD Tracks
- Encodes to flac, mp3 or ogg
- id3 tags encoded songs
- Creates an playlist (m3u) file
- Can prepare and send a CDDB submission.
Enhancements:
- Some minor bugs were fixed.
- The following options have been introduced: merge, resume, md5sum (to create MD5-sum files for each type of sound file), core (to allow several encoding processes on each machine), fpermission and dpermission (to set directory and file permissions), ghost (an experimental feature to split wavs with silence into chunks of sound), prepend and extend (to enlarge chunks of sound when split with the ghost option), and ejectcmd and ejectopt.

GEXEC is a scalable cluster remote execution system which provides fast, RSA authenticated remote execution of parallel and distributed jobs.
It provides transparent forwarding of stdin, stdout, stderr, and signals to and from remote processes, provides local environment propagation, and is designed to be robust and to scale to systems over 1000 nodes. Internally, GEXEC operates by building an n-ary tree of TCP sockets and threads between gexec daemons and propagating control information up and down the tree. By using hierarchical control, GEXEC distributes both the work and resource usage associated with massive amounts of parallelism across multiple nodes, thereby eliminating problems associated with single node resource limits (e.g., limits on the number of file descriptors on front-end nodes). The initial release of the software is made of a daemon, a client program, and a library that provides programmatic interface to the GEXEC system.
Enhancements:
- Modified xinetd file to set LD_ASSUME_KERNEL="2.2.5" to deal with LinuxThreads not implementing all POSIX cancellation points
- Modified gexec.spec.in to use a build root so RedHat 9s broken version of rpmbuild builds without the infamous "getOutputFrom(): Broken pipe" error.

The Persistence of Vision Ray-Tracer creates three-dimensional, photo-realistic images using a rendering technique called ray-tracing. It reads in a text file containing information describing the objects and lighting in a scene and generates an image of that scene from the view point of a camera also described in the text file.
The Persistence of Vision Ray-Tracer(tm) was developed from DKBTrace 2.12 (written by David K. Buck and Aaron A. Collins) by a bunch of people (called the POV-Team?) in their spare time. The headquarters of the POV-Team is on the internet (see "Where to Find POV-Ray Files" for more details).
The POV-Ray package includes detailed instructions on using the ray-tracer and creating scenes. Many stunning scenes are included with POV-Ray so you can start creating images immediately when you get the package. These scenes can be modified so you do not have to start from scratch.
In addition to the pre-defined scenes, a large library of pre-defined shapes and materials is provided. You can include these shapes and materials in your own scenes by just including the library file name at the top of your scene file, and by using the shape or material name in your scene.
Ray-tracing is not a fast process by any means, but it produces very high quality images with realistic reflections, shading, perspective and other effects.
Ray-tracing is a rendering technique that calculates an image of a scene by simulating the way rays of light travel in the real world. However it does its job backwards. In the real world, rays of light are emitted from a light source and illuminate objects. The light reflects off of the objects or passes through transparent objects. This reflected light hits our eyes or perhaps a camera lens. Because the vast majority of rays never hit an observer, it would take forever to trace a scene.
Ray-tracing programs like POV-Ray start with their simulated camera and trace rays backwards out into the scene. The user specifies the location of the camera, light sources, and objects as well as the surface texture properties of objects, their interiors (if transparent) and any atmospheric media such as fog, haze, or fire.
For every pixel in the final image one or more viewing rays are shot from the camera, into the scene to see if it intersects with any of the objects in the scene. These "viewing rays" originate from the viewer, represented by the camera, and pass through the viewing window (representing the final image).
Every time an object is hit, the color of the surface at that point is calculated. For this purpose rays are sent backwards to each light source to determine the amount of light coming from the source. These "shadow rays" are tested to tell whether the surface point lies in shadow or not. If the surface is reflective or transparent new rays are set up and traced in order to determine the contribution of the reflected and refracted light to the final surface color.
Special features like inter-diffuse reflection (radiosity), atmospheric effects and area lights make it necessary to shoot a lot of additional rays into the scene for every pixel.
Main features:
- Easy to use scene description language.
- Large library of stunning example scene files.
- Standard include files that pre-define many shapes, colors and textures.
- Very high quality output image files (up to 48-bit color).
- 16 and 24 bit color display on many computer platforms using appropriate hardware.
- Create landscapes using smoothed height fields.
- Many camera types, including perspective, orthographic, fisheye, etc.
- Spotlights, cylindrical lights and area lights for sophisticated lighting.
- Photons for realistic, reflected and refracted, caustics. Photons also interact with media.
- Phong and specular highlighting for more realistic-looking surfaces.
- Inter-diffuse reflection (radiosity) for more realistic lighting.
- Atmospheric effects like atmosphere, ground-fog and rainbow.
- Particle media to model effects like clouds, dust, fire and steam.
- Several image file output formats including Targa, BMP (Windows only), PNG and PPM.
- Basic shape primitives such as ... spheres, boxes, quadrics, cylinders, cones, triangle and planes.
- Advanced shape primitives such as ... Tori (donuts), bezier patches, height fields (mountains), blobs, quartics, smooth triangles, text, superquadrics, surfaces of revolution, prisms, polygons, lathes, fractals, isosurfaces and the parametric object.
- Shapes can easily be combined to create new complex shapes using Constructive Solid Geometry (CSG). POV-Ray supports unions, merges, intersections and differences.
- Objects are assigned materials called textures (a texture describes the coloring and surface properties of a shape) and interior properties such as index of refraction and particle media (formerly known as "halos").
- Built-in color and normal patterns: Agate, Bozo, Bumps, Checker, Crackle, Dents, Granite, Gradient, Hexagon, Leopard, Mandel, Marble, Onion, Quilted, Ripples, Spotted, Spiral, Radial, Waves, Wood, Wrinkles and image file mapping. Or build your own pattern using functions.
- Users can create their own textures or use pre-defined textures such as ... Brass, Chrome, Copper, Gold, Silver, Stone, Wood.
- Combine textures using layering of semi-transparent textures or tiles of textures or material map files.
- Display preview of image while rendering (not available on all platforms).
- Halt and save a render part way through, and continue rendering the halted partial render later.

fig2ps is a perl script which converts xfig files to postscript or PDF, processing text with LaTeX. fig2pss primary aim is to produce documents (such as articles) with a high quality, in which the pictures are seamlessly integrated with the text (notably, the font in the figures is exactly the same as in the text).

The way to use it is simple : draw your picture with xfig, marking all text as special (there is one way to force this, look at the manual page). Then, invoke fig2ps on your xfig file. Then, you can integrate the picture in a LaTeX document by simply saying, for instance, includegraphics{file}
