Help/Consulting System
This is prototype software for a help/consulting system called Answer Garden. Below is a very short description:
Answer Garden allows groups to develop databases of commonly asked questions that grow "organically" as new questions arise and are answered. It is designed to help in situations (such as field service organizations and customer "hot lines") where there is a continuing stream of questions, many of which occur over and over, but some of which the group has never seen before. The system includes a branching network of diagnostic questions, as well as facilities for other retrieval engines, to help users find the answers they want. If the answer is not present, the system automatically sends the question to the appropriate expert, and the expert returns the answer as well as inserts it into the branching network. Thus, the information database of answers and diagnostic questions grows over time. Experts can also modify this network and database in response to users' problems.
You can find a longer description of the purpose of Answer Garden in the Proceedings of the ACM Conference on Office Information Systems, 1990.

Fractal Movie Video Compression
This is a first release of a fractal video codec developed at the University of Stuttgart.
This code is based on the following work:
F. Dudbridge: Image approximation by self affine fractals. Ph. D. Thesis, University of London, 1992.A short overview is given inD. M. Monro and F. Dudbridge: Fractal approximation of image blocks. Proceedings ICASSP '92, pp. 458 - 488.The codec consists of an encoder (named kodi) and a decoder (named deko). The encoder is not very good in it's compression / image quality ratio (far away from MPEG), but it is quite fast.The programcode compiles under several 1(tm)-like systems (including SunOS, HPUX, AIX, IRIX, OSF/1, Linux), the decoder requires X11 (it's easy to compile a version without display, but it's not done yet).
The encoder reads raw ppm images (P5 and P6 format) and writes a compressed file that could be decompressed by the decoder. The decoder can write the decoded frames to files or display them on a X11 display. There are 3 dithering options available: graylevel (8bit), pseudocolor (8bit) and truecolor (24bit, very slow).

Mathematical Recreation Software
The mathrec package includes several X11 clients written by Dr. Ronald Joe Record who holds a Ph.D. in Mathematics from the University of California. Programs in the mathrec package include :
- endo - calculate and display iteratated endomorphisms of the plane
- lyap - calculate and display Lyapunov exponents of the iterated logistic map
- stars - calculate and display a star field with controls
- coral - calculate and display a coral growth simulation
- gasket - calculate and display Serpinski gaskets
- hop - calculate and display iterated parametric equations
- julia - calculate and display Julia sets
- mandel - calculate and display Mandelbrot sets (clicking the middle mouse button on a point in the Mandelbrot set will generate a window with the corresponding Julia set)
- lds - calculate and display Lattice Dynamical Systems (also known as coupled map lattices)
- madness - calculate and display various kinds of curves and stuff
- splines - calculate and display spline curves
- spore - calculate and display simulated spore growth
- xtopo - calculate and display simulated topographic maps
- xwator - calculate and display a simulation of fish and shark population dynamics over time
Most of the programs in the mathrec package work best with an 8 bit PseudoColor visual (i.e. 256 colors in a colormap). However, they can be run with a TrueColor visual (some features will not be present).
Many interesting sample runs are provided as shell scripts in subdirectories in /usr/local/mathrec. For instance, sample runs of the lyap program with preset parameters are in the directory /usr/local/mathrec/lyap and those for the endo program are in /usr/local/mathrec/endo.
For additional details on these programs, see the mathrec HTML documents.
SNNS - Stuttgart Neural Network Simulator
http://www-ra.informatik.uni-tuebingen.de/SNNS/
SNNS (Stuttgart Neural Network Simulator) is a software simulator for neural networks on Unix workstations developed at the Institute for Parallel and Distributed High Performance Systems (IPVR) at the University of Stuttgart. The goal of the SNNS project is to create an efficient and flexible simulation environment for research on and application of neural nets.
The SNNS simulator consists of two main components:
The simulator kernel operates on the internal network data structures of the neural nets and performs all operations of learning and recall. It can also be used without the other parts as a C program embedded in custom applications. It supports arbitrary network topologies and, like RCS, supports the concept of sites. SNNS can be extended by the user with user defined activation functions, output functions, site functions and learning procedures, which are written as simple C programs and linked to the simulator kernel.
- simultor kernel written in C
- graphical user interface under X11R5 or X11R6
Currently the following network architectures and learning procedures are included:
A number of network pruning algorithms are available as well:
- Backpropagation (BP) for feedforward networks
- vanilla (online) BP
- BP with momentum term and flat spot elimination
- batch BP
- BP with Chunkwise Updating
- Counterpropagation
- Quickprop
- Backpercolation 1
- RProp
- RProp with Weight Decay
- Generalized radial basis functions (RBF)
- ART1
- ART2
- ARTMAP
- Cascade Correlation
- Dynamic LVQ
- Backpropagation through time (for recurrent networks)
- Quickprop through time (for recurrent networks)
- Self-organizing maps (Kohonen maps)
- TDNN (time-delay networks) with Backpropagation
- Jordan networks
- Elman networks and extended hierarchical Elman networks
- Associative Memory
- RBF_DDA
- Simulated Annealing
- Monte Carlo.
- Pruned-Cascade-Correlation
The graphical user interface XGUI (X Graphical User Interface), built on top of the kernel, gives a 2D and a 3D graphical representation of the neural networks and controls the kernel during the simulation run. In addition, the 2D user interface has an integrated network editor which can be used to directly create, manipulate and visualize neural nets in various ways.
- Optimal Brain Damage (OBD),
- Optimal Brain Surgeon (OBS),
- Skeletonization,
- Magnitute based pruning (Mag).
Stacey Campbell's Mandelbrot Program
stacey is an X client for exploring the Mandelbrot Set. It needs the Motif, X toolkit and X libraries to compile. It has been successfully compiled with the SCO X11R4, X11R5 and X11R6 development systems, and the SCO OSF/1 Hercules/1 dev sys. See the Makefile for more details. It runs on 16 color and 256 color X servers with PseudoColor colormap support. Other colormap sizes will probably work.
Select the area to be investiagated using the standard rubberband technique of pressing down the mouse button, dragging out the desired area, then releasing the mouse button. Stacey saves files in xwd format. It does not read in files. It can read coordinates from an .Xdefaults file, see the resources in mandel.c. Here's the keyboard usage:
- 'r' - use red colormap
- 'g' - use green colormap
- 'b' - use blue colormap
- 'm' - use mono colormap
- 'c' - use colorwheel colormap [default]
- 'n' - use default colormap [cannot be rotated]
- 's' - use stripe colorwheel colormap
- 'a' - use non-green colormap
- 'R' - toggle colormap rotation
- '1'..'9' - change colormap rotation speed
- 'x' - reverse colormap rotate direction
- 'd' - dump current fractal to file "mandel.xwd"
- space - double K value (depth of calculation) [default 128]
- 'i' - toggle between generation algorithms
- 'q' - quit program
The original program was culled from _The X Window System - Programming and Applications with Xt_, OSF/Motif Edition, by Douglas Young. It has changed somewhat dramatically since then, but its roots are evident. The original Mandelbrot generation code was derived from the section "Do It Yourself" in _The Beauty of Fractals_, by H.-O. Peitgen and P.H. Richter (see image1.c). My hack to optimize by filling areas of like color was inspired by John Gossman's article in alt.fractals concerning Contour Crawling (though it does not use his and Scott Sherman's code) (see image.c). I expect their code does much better optimizations but I couldn't get it working. The rainbow, red, green, and blue colormap code and keyboard interface code come straight from Hiram Clawson's color3 client, part of which was extracted from Foley and van Dam (see mandel.c). The window dumping source is a slightly modified xwd.c from the MIT X11R4 source distribution, originally written by Tony Della Fera at DEC back in 1985. The colormap rotation code comes from Dave Lemke's xrotmap client. The icon bitmap was created using Jef Pozkanzer's pbmplus utlities. Wing Eng helped by answering my Motif resource questions. As far as I can tell, all of the above people have kindly allowed their source to be used in other peoples' code subject, in places, to the usual restrictions on acknowledgments and sale.
X Accountant - an easy to use Motif finance package
X-Accountant is a program to keep track of your finances. Some of the features are:
- Multiple accounts, which can be open at the same time. Create one xacc account for each of your bank accounts.
- Each account keeps a running balance and a reconciled balance, so you can keep track of the checks that have cleared your account.
- A simple interface. If you can use the register in the back of your checkbook, you can use xacc.
- Automatic account reconciling. At the end of the month, open up the reconcile window, enter your bank statement's ending balance, and check off the transactions that appear in the bank statement. This makes it easy to track down any discrepancies.
- QuickFill... if you begin typing in the description field, and the text matches a previous transaction, hitting TAB will copy that previous transaction. Handy if you have similar transactions on a regular basis.
- Stock/Mutual Fund Portfolios. Track stocks individually (one per account) or in portfolio of accounts (a group of accounts that can be displayed together).
- Quicken File Import. Import Quicken Version 3.0 QIF files.
Advanced Features
X-Accountant offers some features not usually found in simpler accounting programs.
- Sub-accounts: A master account can have a hierarchy of detail accounts underneath it. This allows similar account types (e.g. Cash, Bank, Stock) to be grouped into one master account (e.g. Assets).
- Double Entry: Every transaction can appear in two accounts; one account is debited and the other is credited with exactly the same amount. With double-entry, a transaction edited in one window will be automatically updated in all other windows showing that transaction, and in both of the accounts.
- Income/Expense Account Types (Categories). When used properly with the double-entry feature, these can be used to create both Balance Sheet and Profits & Losses reports. For example, savings account interest, stock dividends, or paychecks can be marked as both a deposit in a bank account, and as income in an Income account type, using the double-entry (transfer) feature. Similarly, credit card charges can be noted in the credit card account, as well as in a corresponding expense account.
- General Ledger: Multiple accounts can be displayed in one register window at the same time. This can ease the trouble of tracking down typing/entry errors. It also provides a convenient way of viewing a portfolio of many stocks, by showing all transactions in that portfolio.
XaoS - Fast interactive real-time fractal zoomer/morpher
XaoS is a protable real-time interactive fractal zoomer/morpher which works under X11, SVGA and text terminals. If you don't know what fractal is or you want to know more about XaoS features you should see the animated tutorial. Run XaoS and press 'H' twice. It is much more fun than reading the boring manual page :) and it supports foreign languages. You might also read xaos.info file for some advanced stuff (like how to write animations and tutorials manually, port or extend XaoS, algorithms used etc.)
Xcalendar - an X11 calendar with notepad
xcalendar is a simple interactive calendar program with a notebook capability. It is built on the X Toolkit and the Athena or Motif Widgets (compile time option). If month and year are not provided on the command line they are assumed to be current.
xearth - planet earth root window
Xearth sets the X root window to an image of the Earth, as seen from your favorite vantage point in space, correctly shaded for the current position of the Sun. By default, xearth updates the displayed image every five minutes. The time between updates can be changed with the -wait option. Updates can be disabled completely by using the -once option. Xearth can also render directly into PPM and GIF files instead of drawing in the root window.
hypertext markup language editor
xhtml is a splitscreen HTML editor allowing amendments of the source document and showing the HTML display of that source. The usual file editing facilities (open, amend, save etc.) are present by either using meta key combinations or by mouse selection via pulldown menus. Also most of the HTML functions such as heading, paragraphs, lists etc are available.
Xinvest - a personal finance package
With Xinvest you can:
Centralize record keeping by storing all transactions in account specific files.
Calculate total and annualized returns including the effects of buys, sells, and dividends. This provides a means of comparing the results of all accounts in a portfolio, be they CDs, bonds, mutual funds, or your checking account.
Receive automatic price updates from Xquote. On receipt of a price update Xinvest will recalculate return information.
View various transaction parameters such as share price, shares per transaction, transaction cost, transaction value (at current price), dividends, internal and total return, and/or cumulative and moving averages of the above. Plots are transaction based bar or date based x-y charts.
View overall value weightings of accounts in a portfolio. Specify categories, what percent of an account is in that category, and which accounts are of interest and Xinvest will tell you the value and percentage of all categories in the defined portfolio. Predefined is a account category to view weighting of accounts in the total portfolio. Categories are hierarchical, so you can zoom into the makeup of your portfolio. View in text and pie chart form.
A Financial calculator with common equations is provided. Included are FV, PV, FV of sum of payments, and periodic loan payments.
Hopefully, all of this is displayed using an easy-to-use, point-and-click interface. There are few command line switches, no dot files, and X resources are limited to color and font selection allowing you to tailor the look of the tool to your own preferences.
Xquote - retrieve stock quotes
Xquote is a WWW based quote retrieval program.
With Xquote you can retrieve quotes for stocks, mutual funds, currencies, or any other type of commodity that has web based quotes available. Xquote is extendible, both in the servers it queries and the types of information it can query. New servers or quote types can be added to the Xquote X resource file without rebuilding Xquote. See 'Adding Servers and Types' for more information.
Xquote is part of a suite of X based investment programs and can communicate quote updates to Xinvest. Xinvest can then update portfolio return and asset allocation calculations, for 'hands free' account updates.
X11 Screen Locker
xlock locks the X server till the user enters their password at the keyboard. While xlock is running, all new server connections are refused. The screen saver is disabled. The mouse cursor is turned off. The screen is blanked and a changing pattern is put on the screen. If a key or a mouse button is pressed then the user is prompted for the password of the user who started xlock.
X11 Screen Saver
The xscreensaver program waits until the keyboard and mouse have been idle for a period, and then runs a graphics demo chosen at random. It turns off as soon as there is any mouse or keyboard activity.
The purpose of xscreensaver is to display pretty pictures on your screen when it is not in use, in keeping with the philosophy that unattended monitors should always be doing something interesting, just like they do in the movies.
However, xscreensaver can also be used as a screen locker, to prevent others from using your terminal while your are away.
The benefit that this program has over the combination of the xlock and xautolock programs is the ease with which new graphics hacks can be installed: you don't need to recompile this program to add a new display mode, you just change some resource settings. Any program which can be invoked in such a way that it draws on the root window of the screen can now be used as a screensaver without modification. The programs that are being run as screensavers don't need to have any special knowledge about what it means to be a screensaver.
fire up programs in case of user inactivity under X
Xautolock monitors the user activity on an X Window display. If none is detected within mins minutes, a program is started as specified by the -locker option. Xautolock will typically be used to lock the screen (hence its primary name) but it really doesn't care what program you make it start. For this reason, xautolock does not interfere with the default screen saver. This implies that it is the job of the locker to take the appropriate actions if the default screen saver is to be disabled. The only real assumption made by xautolock is that a new countdown starts as soon as the locker exits.
Xmailbox - an X11 mail reminder
The xmailbox program displays, by default, an image of a mailbox. When there is no mail, the image shown is that of a mailbox with its flag down. When new mail arrives, the image changes to that of a mailbox with the flag up, its door open and a letter visible inside. It can also optionally play a sound through the Open Sound System audio driver for SCO. In addition, the user can optionally invoke his/her favourite mail retrieving program.
This program is nothing more than a wrapper around the Mail- box widget included with the program's source distribution.
X11 Astrology Charts
Create astrological charts for yourself, your friends, your family and impress your neighbors. Astrolog does basic charts plus a whole lot more: biwheels, aspect grids (with midpoints), Gauquelin sector wheels, astro-locality maps and graphic ephemerides - to name only a representative sample of the program's capabilities.
VT102 terminal emulator
rxvt - version 2.4.5 - is a color vt102 terminal emulator intended as an xterm(1) replacement for users who do not require features such as Tektronix 4014 emulation and toolkit-style configurability. As a result, rxvt uses much less swap space - a significant advantage on a machine serving many X sessions.
In order to update the utmp entry, the rxvt binary needs to have write permission on /etc/utmp. In order to accomplish this, it can be installed "setuid root". On some platforms, it is sufficient to install it "setgid adm".
Interactive X Diary/Calendar
xdiary is an X application that displays a calendar in one of two formats and/or an interactive daily diary.
X11 Screen Grabber
xgrabsc lets you grab arbitrary rectangular images from an X server and writes them to standard output in a variety of formats.
Command line options also allow reduction of colormaps, halftoning and dithering of color images, and direct map- ping of color images to monochrome.
Simple Paint Program
XPaint is a color image editing tool which features most standard paint program options, as well as advanced features such as image processing algorithms. It allows for the editing of multiple images simultaneously and supports various formats, including PPM, XBM, TIFF, JPEG, etc.
The functionality of XPaint is divided into a toolbox area for selecting the current paint operation and paint windows for modifying/creating images. Each paint window has access to its own color palette and set of patterns, although the paint operation in use is globally selected for all windows.
XPaint runs on a variety of displays. It should be noted that saving images will adapt them to the current display type (i.e. a color image loaded on a greyscale screen will be saved as a grey image).
There is also an extensive on-line help system available.
X11 Rolodex
xrolodex is a small, rolodex-like application for X Window System environments. It has a Motif-based user interface. Each button and menu for xrolodex is described in detail in the help system.
Tide and current predictions
XTide is a package that provides tide and current predictions in a wide variety of formats. Graphs, text listings, and calendars can be generated, or a tide clock can be provided on your desktop.
XTide can work with X-windows, plain text terminals, or the web. This is accomplished with three separate programs: the interactive interface (xtide), the non-interactive or command line interface (tide), and the web interface (xttpd).
The algorithm that XTide uses to predict tides is the one used by the National Ocean Service in the U.S. It is significantly more accurate than the simple tide clocks that can be bought in novelty stores. However, it takes more to predict tides accurately than just a spiffy algorithm -- you also need some special data for each and every location for which you want to predict tides. XTide reads this data from harmonics files that you must download along with the distribution.
Ultimately, XTide's predictions can only be as good as the available harmonics data. Due to issues of data availability and of compatibility with non-U.S. tide systems, the predictions for U.S. locations tend to be a lot better on average than those for locations outside of the U.S. Nevertheless, there are satisfied XTide users all over the world. It is up to you to verify that the predictions for your locale match up acceptably well with the officially sanctioned ones, and to let the author know if they do not.
- Deviations of 1 minute from official predictions are typical for U.S. locations having the latest data.
- Deviations of 20 minutes are typical for non-U.S. locations or U.S. locations that are using obsolete data.
- Much longer deviations indicate a problem.
X11 Webster Client
Xwebster is used to look up words in the online copy of Webster's dictionary. It puts up an application window that contains subwindows to interact with the user and display the results. The top half has a browser window in which alternative words will be shown, below that is a row of windows consisting of an interaction window where the user may enter words to be looked up, and buttons which the user may click on to select a program function. The lower window is used to display the definitions that are found.
X11 Fish Tank
Xfishtank displays a wide variety of fish and assorted sea creatures swimming on your root window.
