Java Chess Program
I have written a java chess program. Go
here to play or download the program.
Stockfish Chess Program for Android Platform
I have ported the stockfish chess engine to the Android platform. The
program is called DroidFish.
HP48/49 programs and links
Here is the latest version of my chess program for the HP48/49. Read
the documentation for more
information or see the changelog
to find out what's new.
HP48/HP49 program + documentation + source code:
Simplex solves linear programming (LP) problems. It works on HP49
calculators and can use exact arithmetic to avoid rounding errors.
Read the documentation for more
information or download the code and test it yourself. The
current version is 1.05. Read the ChangeLog to see what is new.

Emacs-P4 integration package
P4 is a very good configuration
management system running on a variety of platforms, including Linux. The
p4.el Emacs Lisp library integrates the P4 commands into emacs. p4.el works
with both GNU Emacs and XEmacs. p4.el is released under the GNU GPL license,
but P4 itself is a commercial product. (But you don't need a license
file for personal use.)
The home page for p4.el has been moved to sourceforge.
I have started a collection of high-level helper functions
for p4.el. It is called p4extra.el and must
be loaded after the p4.el package. It currently contains two functions:
- p4-integrate-change, which simplifies the task of integrating a p4
change from one branch to another.
- p4-revert-interactively, which interactively lets the
user revert some (or all) opened files.
I have also written a p4merge script that
can be used as a $P4MERGE program for the "p4 resolve" command. This script
relies on the simplemerge.el major mode
for emacs. The simplemerge major mode should be generic enough to be used
for resolving conflicts with CVS and perhaps other revision control systems
