Born
in 1941. Married. Hans has two children. He lives in the country at 20
kilometres from Eindhoven (NL). His background is chemistry and theoretical
physics. His final study concerned the fundamentals of physics, in
particular quantum logic and quaternionic quantum mechanics. Hans started
his carrier in 1970 in the development department for high-tech electronic
devices. He stayed there for more than fifteen years. He built or changed
most of his measuring equipment. In the beginning he used analog techniques
later he turned to digital technology. During that second period Hans used
software increasingly for simulation and measurement control. As part of
his job he participated in the standardisation commissions that established
the ISO and the IEC standard for measuring the optical transfer function
(OTF, MTF). In 1987 Hans changed his job direction and joined an internal
software house. He participated in several large and very complicated
projects and did a series of single person projects. Mostly it was work
that others did not dare to touch because of the complexity and the
scientific depth involved in the subject. In this way Hans learned the
programming metier the hard way. In this way he became a senior and he has
experienced most of what can go wrong and what goes well in software
engineering. In the process Hans developed a vision on software production
that he likes to share with you.
Since
July 2001 Hans is retired from his job as a senior system software engineer
at a local semiconductor company. From that instance until 2004 he
proceeded with the work that he started in 1995 and spent all his time and
energy in the development of ingredients that are needed to establish an
open market for embeddable software components. These components are aimed
at resource-restricted real-time embedded systems. Tools and technology
have been created that support the universal creation, publishing and
retrieval of formal specification documents. Tools that will be capable to
use formal specifications to create skeletons of software components and
working and testable prototypes of component-based systems will follow. The
tools are all crafted in C# and work on .Net compatible platforms. In 2004
this design work stopped. From 2004 through 2006 Hans worked on the
automation of the expert work of a physiological institute. In 2006 Hans
retired and used his free time to study again the fundamentals of physics.
He designed an unorthodox way to do quantum physics. This project is named
“The Hilbert Book Model”. It delivers an unprecedented view at the deep crofts
of physics. Hans owns a personal e-print archive at http://vixra.org/author/j_a_j_van_leunen
