Monte-Carlo Test Method

September 10, 2019

A Number of years ago, I had a contract to build a hardware
control sub-system software product.

This hardware control sub-system was designed to control
legacy hardware shipped back from the Middle East.

This legacy hardware appeared to have not been well-maintained;
it needed a lot of service.

I was afraid that I might break this hardware when I tested my
hardware control sub-system software product.

I developed a Monte-Carlo Simulator/Stimulator Test System to
validate my hardware control sub-system product.

The Monte-Carlo technology is based on a pseudo-random generator.
It was originally used in the development of nuclear weapons.

The random nature of my Monte-Carlo Test System enabled me to
rapidly and thoroughly test the hardware control sub-system, both
from a user and hardware point-of-view.

The use of a Monte-Carlo Simulator/Stimulator Test System
enabled me to deliver an error-free software product.

WHATIFWE used Monte-Carlo software test methods for all software.
Would we get better products?

The Twitter Seminar On The Development of Error Free Software Continues — Session 5

CAN WE PREVENT ERRORS DURING SOFTWARE DEVELOPMENT?

It is important to detect and properly respond to an error
condition during the execution of the product.

It is also very important to prevent errors in the software
development process.

Perhaps we should look again at the development of military
hardware, circa, 1980’s.

In the hardware world, Quality Assurance begins with the
selection of a set of parts.

Management selected a set of Integrated Circuits and the
Engineers were required to use them in the design.

Would you believe it if I told you that there is an software
equivalent to the integrated circuit?

There is a “software part” equivalent and it is not an object
(which is more like a circuit board).

We can find our “software part” in the history of software
engineering.

Specifically, it is the macro instruction set in the
macro-assembler circa 1990.

These macros were used to define common multi-instruction
processes such as 4-byte addition in a Z80 machine.

Once defined, these macros were never changed. They became
standard “Software Parts”.

Unfortunately, the use macro instruction set was optional
in the development of an assembly language program.

WHATIFWE had development software tool that produced source
code exclusively from a set of macros?

Limitation to My Response to Your Comments

September 6, 2019

Every day I receive between 50 and 100 comments. Many of these comments request information or advise from me.

I appreciate the honour of your request for information.

Unfortunately, there is only one of me managing and writing the blog. Consequently, I simply do not have enough time to reply to each of your questions.

There are many comments that ask the same question. In these situations where I have the information, I will provide my knowledge in a post, time permitting.

I will respond to any comment made by a person who is experimenting with my software development tools.

Thank You

“Class Preparation” Libraries

Both the functional and error tests of the
“ARITHMETIC LIBRARY” are complete. The library
is now ready for experimental use. The next
project

The next “Class Preparation” Library to be
developed will be for processing the “If” “Then”
and “Else” statements. The library name will be
classcommonconditional

“Class Preparation” Libraries

The preparation of the software parts defining the
classcommonconditional library has begun.

The Role of the Media

September 3, 2019

Both the incompetent and the competent benefit from
media attention.

The competent leader requires community participation.
The media helps him to obtain the participants.

The incompetent needs 15 minutes of fame. The media
helps him to satisfy his greedy goals.

Unfortunately the entertainment associated with the
incompetent attracts a lot of media attention.

The competent pioneer finds new solutions to current
problems.

WHATIFWE were to provide the media attention needed
to develop hope from the new ideas of the competent
pioneers?
