Fractal
Generator
A number of years
ago, my Dad, G. M. Gentry, retired from CITGO. In addition to his
regular Chemical Engineering work, he was also involved in Computer
Programming. Once retired, he invested in a Dell P-350, which he
still has, and Visual Basic. In his spare time, which most retired
folks have plenty of, he wrote a very user friendly Fractal Generator
program. What is a Fractal you ask? A fractal is a rough or
fragmented geometric shape that can be subdivided in parts, each of which
is (at least approximately) a reduced-size copy of the whole. Fractals are
generally self-similar and independent of scale. There are many
mathematical structures that are fractals; e.g. Sierpinski triangle, Koch
snowflake, Peano curve, Mandelbrot set, and Lorenz attractor. Fractals
also describe many real-world objects, such as clouds, mountains,
turbulence, and coastlines, that do not correspond to simple geometric
shapes. Benoit Mandelbrot gives a mathematical definition of a fractal as
a set for which the Hausdorff Besicovich dimension strictly exceeds the
topological dimension. However, he is not satisfied with this definition
as it excludes sets one would consider fractals. For additional
information click HERE.
To download Mr. Gentry's Fractal Generator (57 kb) click on the button
below. It is in a Zip file so you must have WinZip
(Free Evaluation Version),
or equivalent to open it once it is on your pc. Be sure to unzip all
components into the same folder on your computer.

Timer
Another cool software
program that my Dad wrote is a PC based Timer. Have you ever been
doing tasks on your computer for a duration of an hour or more, when you
suddenly released that you were suppose to take care of that chore your
dad told you about 45 minutes ago? Or, while you were chatting with
that Facebook friend for the last 2 hours, you suddenly remember you were
suppose to pick up your little brother at football practice at 4 pm.
(just wait till mom comes home - dead meat) . Now you can set up and
run a timer on your computer, complete with MIDI files of your
choosing. An interval timer is included that produces an audible alarm (MIDI)
at the completion of the desired interval. This interval can be set to any value between 1 minute and 12 hours.
Because of the ease of loosing track of time at the keyboard the interval timer can be used as a reminder that you are needed elsewhere.
The count down timer alarm can de selected from a list of 3 MIDI files that are included. At the completion of the specified timer
interval the program plays the selected alarm MIDI and then cycles through the complete MIDI library repeatedly until the "Stop Alarm"
button is clicked. Any or all of the above MIDI files can be removed from the alarm
list by deleting them from the application folder. At least one MIDI file is required for the program to function properly.
MIDI files of your choice can be added to the alarm list simply by adding them to the application folder.

Convert
v.4.10
Have you ever had a need to know
how many grams were in a pound? How about how many centimeters in an
acre, or even how many calories in a BTU? The is an easy program
called Convert v. 4.10 that will do these things and more. Convert is
an easy to use unit conversion program that will convert the most popular
units of distance, temperature, volume, time, speed, mass, power, density,
pressure, energy and many others, including the ability to create custom
conversions! This software was created by Josh
Madison and is free for download. The
file is small and is stand alone ( 157 kb ).

This site used to have a
really cool Flash based clock. Though it does not appear to have the
clock anymore, it does have some unusual interactive scripts.....which I
have yet to figure out. Maybe you can......

Atomic
Clock Sync 2.6
If your clocks must have the
"exact" time, then Atomic Clock Sync is for you. This
program will reference an atomic clock server to get the current time with
the greatest accuracy available and update your PC's information. It can
even be set to automatically check the time once a day to keep your PC's
time accurate forever. Atomic Clock Sync will connect to one of the time
servers operated by the National Institute of Standards and Technology (NIST)
in the United States, and will compare the time of your computer with the
time on the servers operated by the NIST. This program will then display the
difference between your system and offer you the option of adjusting your PC
by the displayed amount.

Periodic
Table
Periodic Table. The only program in its category to give such a huge amount of information at such a small file size with a fully professional interface.
Periodic Table is a very simple program, which displays the various properties of the elements of the modern Periodic Table when the buttons containing the symbol and atomic number of the element is clicked. The program currently displays the following properties:
1.Atomic number – The atomic number of the element.
2.Name- The English name of the element.
3.Atomic weight- The atomic weight of the most stable isotope of the element.
4.Electronegativity – The electronegativity of the element
5.Ionisation Potential – The ionisation potential of the element.
6.Atomic Radius-The average atomic radius of the element.
7.Electron Arrangement- The arrangement of electron in the various shells in the atom.
8.Symbol- The symbol of the element.
9.Melting Point-The temperature at the element melts.
10.Density- The density of the element measured in kg/m^3 at STP
11.Chemical properties and Uses- This section displays the important chemical reactions of the element, its practical uses and other important facts about the element. This
file is small and free for download. (136 kb)

Memory
Status
Another cool small profile
program that my dad wrote a while back is called Memory Status. A
stand alone piece of software at only sixteen kbs, it will display your
pc's percent of physical memory in use, available physical memory, total
physical memory, total page file bytes, free bytes of page file, total
virtual memory bytes, and free virtual memory bytes. Updating 5
times per second, this file is worth the download.
