In Chronological Order.
It all started with my
love for Mathematics, and Operations with Matrices Transformations (the basis for Computer
Graphics). Founded and registered SCIENTIFIC SOFTWARE in
1979 in Suffolk County,
NY. Copyrighted my
first extensive software creation that same year. It was a 3-D program
-written in BASIC
language- that would load a matrix with the coordinates of the vertices of a
pyramid or prism,
or radius and height of a cylinder. Then the program would query for parameters that were to be used to fill the
Transformation matrix (scaling, rotation over X-Y-Z axis, shearing,
translation ). Simply by
multiplying matrices the new “transformed” points of the solid would be
calculated and plotted on the monitor’s screen.
Under your eyes the solid was moving or transforming. That
was something! All that done with 10Kb
OS (ROM), and 32Kb RAM.
The "micros" we used in those days (Comordore, Apple, Radio
Shack TRS 80, and Atari 800) were really rudimentary slow platforms for
today’s standards. Yet, it was a
lot faster than doing calculations by hand, step-by-step (as we used to do at the
University a few years earlier).
Then moved into more financially
rewarding venues: Business
Applications. Started to work on a “manipulator of data
banks”, I do not think the term database was in use as yet.
In 1978 we
would refer to these programs as manipulators of Cross-Referenced Archives.
Oracle did not exist (actually existed, Lawrence
Ellison had founded it in 1977), and Bill Gates was still in the
early stages of trying to start Micro-soft
(as the company was named
when Bill Gates and Paul Allen founded it in 1975).
INTEL and Fairchild were basically the only high-tech in Silicon
Valley. Apple and
the new kids in town (referring to San Jose and Sunnyvale, CA).
Very little software existed that would run business
application. It was not easy to find somebody who would make these
5.25" diskeettes sleeves.
Living on Long Island (Wheatley
working in Manhattan’s Park Ave (British Airways) , I had to spend five
hours in daily commuting, mostly on the Long Island Rail Road.
To dedicate an average of six more hours daily on my software hobbies did
not leave me much time for family or sleep.
Rather than divorcing my wife opted for resigning from my
airline job. Sold my Long Island home, and relocated to Puerto Rico,
where with a lower cost-of-living I could stretch the equity of the sold house.
In January of 1981 I opened the doors of
the new Scientific
Software in Old San
Juan, PR. Now I
could dedicate full time to my entrepreneurship!
serious database business application for a micro-computer was unheard off
Software for micros was a scarce, and a
novelty. The term software was
not recognized by most people, but the term "computer program"
John Xuna, 32 years old (until 1986 I was known by my birthname,
Picture taken in 1981
soon after opened for business. Located at Recinto Sur St. in Old San
Juan, PR. The "platform" and Atari 800, the monitor being an old TV
connected via RF modulator.
In early 1982 I
finished a database application for dairy farmers. It was called
D.M.I.S (it spelled
Archive's manipulator -
Dairy Management Information System). As
said before, the term database was not formally in
use. If it was in use, I was not aware of. The
software name end up being my family's new last name: XUNA (legal name
change in 1986). The program's design efficiency was achieved by a software
methodology that I named "Nucleolic Programming", which has been copyrighted
with the Library of Congress. More about these techiques I will eventually
published at www.Nucleolic.com,
domain that I have owned for more than a decade.
its novelty, several newspapers and magazines wrote articles about my
venture, and the possible impact on dairy farms. Yet, for lack of venture capital,
I was forced to close down operations in 1984. This newly emerged
type of software was unfamiliar territory for venture capitalists in that Commonwealth island of Puerto Rico.
A decade later
-in 1992- started a second entreprenurial effort in Two Rivers, Wisconsin.
There I found
"Animal Science Software International".
Confronted again with lack of
capital, despite good accolades from farmers and journalists, A.S.S.I followed the same fate as
Scientific Software, operations had to be closed down. Click on tab "News
& Articles" to get an idea of what the press was saying about this
software, or its creator.
XUNACA was the
name given to the combination of hardware, plus the XUNA D.M.I.S. software
