differential equations. Features include several problem classes
provided with current distribution, support for unstructured meshes
with local refinement and coarsening in 2-D and 3-D, an interactive
GUI for X11, a flexible scripting langauge, an advancing front grid
generator in 2D, and about 1000 pages of online and PostScript
Unix Cockpit (uc)
- Unix Cockpit version 1.4, a nifty X11 filemanager with multiple
a directory tree, integrated shell, custom menus etc.
Unix Reference Desk
- This site has UNIX and UNIX-related manuals out the wazoo.
- A Scheme-based, programmable, extensible troff translator
with a back-end for HTML. It reads and parses UNIX troff documents
and translates the embedded markup into a different format. The
translation process is controlled by a set of user-supplied
procedures written in Scheme. The most recent version (1.0)
includes back-ends for translating documents using the "man"
and "ms" macros into HMTL 2.0. The source code, which can
be compiled using Elk
and an ANSI C compiler, is available as well as binaries for
several platforms including Linux.
- A source level C debugger that runs under X windows.
- A package of programs and subroutines for tracking satellites.
This is written in C.
Utah Raster Toolkit (urt)
- Utilities for graphics file conversions.
- A re-engineered version of the Iris ViewKit put out by SGI.
It is source code compatible with the Iris ViewKit except in
a few instances, so it should contain enough classes to write
- A software system for visualizing output from numerical weather
models and similar sources. It works on data in a 5-D format, i.e.
three space dimensions, a time dimension, and a dimension for
enumerating multiple physical variables. It is also capable of
performing volume rendering, quickly on machines with special
hardware and much more slowly via software. It is available as
source code and as an SGI binary. I've successfully compiled
and installed this on my Linux box, although since I've only
got 16 Mb of RAM it runs a wee bit slow (24 Mb being the
recommended minimum). Other than the speed thing, it's an
impressive piece of software for displaying and animating
- A computer graphics and vision environment requiring
the Motif widget set.
- A portable software library for volume rendering.
- A VRML browser for 3-D scenes and worlds usable with
WWW browsers. This software (and project) is intended to
complement forthcoming commercial VRML browsers and
provide a platform for research and experiment. Binary
versions are available for several platforms, including
- This is an integrated Motif graphical user interface
builder. A working Motif GUI can be built in minutes by
pointing and clicking on predefined icons which represent
Motif widgets, then dragging and dropping them on the
design space. A Linux binary statically linked to the
Motif widget library is available.

Wide Web. The features include support for different fonts in
in X Windows and using Emacs 19, Epoch or Xemacs, mouse support,
forms support, compatibility with Mosaic hotlist files,
compatibility with Hyperbole, and more. It is very portable and
will pretty much run on every platform on which Emacs will run.
To use it fully the following ancillary packages are necessary:
nntp, ange-ftp, gopher, html-mode and mailcrypt. Details for
obtaining them are available at the given site.
- A generic public domain full-featured hypertext server
which can be used as a regular HTTP server. It can be used
to server hypertext and other documents and also as a proxy--
a server on a firewall machine--that provides access for
people inside a firewall to the outside world. This is supposed
to compile and run on Linux platforms with no difficulties. A
guide to installing this can be found in the May 1995 issue of
the Linux journal.
W3C Line Mode Browser
- A character-based Web browser developed for use on terminals.
It was developed using the
W3C Reference Library as an example
of a client application and as a test tool for quick access to
the Web from scripts, cron jobs, etc. It can be run in
interactive mode, non-interactive mode, as a proxy client,
and gives a variety of possibilities for data format conversion,
filtering, etc. Unlike
Lynx, another line mode
browser, this was primarily intended as a test tool. This
has been compiled with no problems on Linux platforms.
W3C Reference Library
- A general purpose code base written in C that can be used as
a basic tool for writing single- and multi-threaded Web clients,
servers, proxies, etc. It contains reference code for accessing
HTTP, FTP, Gopher, News, WAIS, Telnet servers, and the local
file system and functionality to handle data objects rendered
in various media types. The
Arena browser was built
using this library. This library is supposed to compile on
Linux boxes with no problems.
- The Widget [Athena] front end is a package that implements
a symbolic, string-based interface to the X Toolkit,
the Athena Widget Set (or the 3-D version thereof, i.e. Xaw3d),
the OSF/Motif Widget set, and various complementary widget
classes and extension packages. With Wafe one can develeop
applications with high-level graphical user interfaces in
the scripting language Tcl, or it can be used mostly as a graphical
front-end that provides an easy access to GUI programming for
various programming languages. The distribution contains quite
a few sample application programs in Perl, GAWK, Prolog, Python,
Tcl, C and Ada. It has been tested and runs on several
platforms, including Linux, and much more information is available
at the given Web site.
- This is the OSF/Motif Widget Interpreter, an interactive
object-oriented user interface language for rapid prototyping,
development and delivery of extensible applications with Motif
GUIs and Xtango graphics/animation. This a language along the
lines of Tcl/Tk or Python for creating
and delivering GUI-based applications. The source code is
available as well as binaries for Linux platforms.
- A collection of WWW applications and hypertext-based information
about Linux. The collection consists of the most recent Netscape
browser, a large collection of Linux documents in various formats,
the most recent NCSA Web server with additional CGI scripts, and
the asWedit HTML editor.
- A daemon for handling anonymous ftp. Its features include
extensive logging, the ability to limit the number of users,
easy configuration changing, extensible support for auto-tar,
and more. The May 1995 issue of the Linux Journal has an article
that describes this and shows how to install it.

written in C. THe XPCE/Prolog interface allows the creation of
instances of these classes as well as their manipulation. New
XPCE classes can also be created from Prolog.
- The X Portable Interface Package is a development tool which
allows the quick construction of GUIs in an X Windows ennvironment.
The interface takes the form of a series of user-definable
