Library." As its name implies, it is a library of general
utilities written in portable C. The core of the library
are the same sort of standard algorithms found in the C++
checksum is a java program that
calculates checksums producing output similar to
md5sum and sha1sum.
Chocolate Pieces is a two player
game. Each player must take 1, 2, 3, or 4 pieces of
chocolate on each move. The player who takes the last
chocolate piece (or pieces) wins. On the other end of the
above link is a computer program. You will always move
first. With perfect play, you can always beat the
computer. One mistake though, and the computer will
always beat you. I did not conceive of the game.

Greatest Common Divisor is a graphical
user interface that finds the greatest common divisor shared
between a fraction's numerator and denominator. It then
reports both the reduced fraction and the greatest common
Harbinger is a Macintosh OSX
application that gives you advance notification of when the
screensaver is about to start.

source (circa 1995) to build with recent versions of gcc and
Jenkins One-at-a-Time Hash
written in Standard ML.
Loan Repayment is a small web-based app that
is sure to depress you. You can get the source for a
stand-alone executable that does the same thing.

text files similar to tail and less but with a few extras.
It has a graphical interface and runs natively on both linux
mergesort.sml is a Standard
ML implementation of merge sort that is slightly faster than
than SML/NJ's ListMergeSort when compiled with mlton.
mgdiff Debian Package
mgdiff-scripts are a set of
scripts for automatically displaying a graphical difference
program like mgdiff, meld, tkdiff, xxdiff, etc. for each
different file as determined by the output of
or one of the following version control systems:
mktemp is a clone of BSD's
"mktemp" which exclusively creates a temporary file for use
by a shell script. I wrote this in straight C because I
needed this functionality on WinNT, and it is currently
missing in the Cygwin utilities. Actually, the mkstemp()
function call is now present, but the "mktemp" executable is
NumberFormat is a simple gui
for displaying the binary format of arbitrary precision
numbers and for converting among common bases like
hexadecimal and octal. Command-line utilities are also
included that do the same thing.
ocaml.mk is a Makefile for ocaml
development. It should be sufficient for small to medium
pad.scm is a module for racket (a dialect of
scheme). This module provides simple implementations of
(pad-left) and (pad-right) which are needed because Scheme's
(format) function does not (to my knowledge) allow the user
to specify field width or alignment.
Path Manager (pathmgr) is a Python script
that makes managing your PATH or other PATH-like enviroment
variables (or any delimited list) easy and portable.
pstree is a relatively portable
awk script that rearranges the output of "ps" into a
parent-child tree. pstree gets its name from several other
common utilities that do something similar. It is known to
work with FreeBSD, NetBSD, OpenBSD, IRIX, Linux, and
Quadratic Equation Solver solves for
complex roots given complex coefficients for second degree
polynomials using the familiar Quadratic Equation.
rational-to-string are Clojure
and Common Lisp packages that allows input or output of arbitrary
precision floating point numbers.
realpath uses the standard C
library call to realpath() in order to strip out back
references and symbolic links.
report_signals is a
simple program that prints to standard output the number and
text description of all the signals (except SIGKILL and
SIGSTOP of course) it receives.
rgb is a small GUI that lets you quickly
try different color combinations from the standard rgb.txt
list of colors or from a custom list of colors in the same
rot13.sh is a simple rot13 encoder
shunt and flyisofs allow you to treat
your CD writer under linux like you would a tape drive.
These two programs make it much more convenient to make
multi-volume CD backups of your Linux system using your
favorite backup software. In fact, by using these two
programs, you can completely eliminate all temporary file
creation and just stream your data straight to your burner.
shunt is also interesting by itself because of its
general utility in making the unix pipeline a more friendly
place to work.
slock is a simple program
that lets shell scripts synchronize around a file lock on a
local file system or one mounted via NFS (provided the NFS
server supports file locking). This is for those times
where perl or python isn't available. The "s" in "slock"
comes from its association with shell scripts.
slock for BSD is the same
as "slock" above but it compiles on more platforms. It is
informative to do a diff on the main.cc in this tarball and
the main.cc in the other tarball above. It will show you
how sigwaitinfo() is simpler to use than sigsuspend() when
you don't need a signal handler to run.
split.cc returns a vector of strings
split on a character delimiter (C++).
split.lg returns a list of strings
split on a character delimiter (Logo).
split.lisp returns a list of
strings split on a list of character delimiters (Lisp).
Simple String class is a simple, dynamic
string class for C.
a string from any type that can be extracted for a
take care of what I consider to be a few oversights in the
strtol(), strtoul(), and strtod() C stdlib routine. It
provides conversion routines for int, unsigned, long,
unsigned long, and double.
StringUtil.java returns a
Vector of String types split on a character delimiter (java).

Investing shows how your money grows given constant
earnings and periodic deposits. As of 2000, if you have an
IRA that grows at a constant 10%/year and if you contribute
$3000.00 annually through equal bi-weekly direct deposits.
At the end of 30 years, your $89996.40 invest will grow to

hash functions using dieharder.
truncate is a short program
that wraps the function of truncate(2). It works as a
faster replacement to dd if=/dev/zero of=<file>.
usleep.c is a wrapper around the
usleep() system call.
verify_atoi() is a "C"
routine that verifies the string you send to atoi is really
an integer. This is necessary because atoi() returns 0 for
both when a zero is read and when the input string is in an
improper format. An alternative is to use strtol() as is
shown in usleep above.
