25 Years of Programming Home Page
Welcome
Welcome to 25 Years of Programming, a collection of open source
programs and
libraries in C++ and other languages, Microsoft Office Access
databases,
Excel spreadsheets,
Word documents, templates,
and macros, and How To
articles and essays on a variety of topics including website security, management, and
design, and safer web surfing. I hope you find things that are useful and interesting.
Site Purpose
The purpose of this website is to publish the hundreds of programs and other computer related
projects that I developed over the past 25 years. They range from simple
beginner-level utilities to complex experiments with
artificial intelligence.
They are mostly open source, GNU GPL licensed, and:
- Have example code and example methods, often
extensively commented. Almost all the code is presented on web pages
for easy browsing, searching, and copying. Large projects also have
.zip download files.
- Are starting points for similar
projects.
- Some, especially the Access, Excel, and Word projects, are useful.
- Some are entertaining.
- Some demonstrate or discuss interesting mathematical or scientific principles
such as machine learning, adaptation, evolution, complex adaptive systems, chaos,
and fractals.
- The vintage Heathkit H-89 and
H-100 programs serve a sentimental and historical purpose
by giving vintage computer owners things to do with their vintage
computers besides look at them.
Publication of the existing projects is nearly complete, but the
website will never be complete. Reflecting how
the journey into the world of computers is a never-ending adventure of
exciting discoveries and new things to learn, recent articles take a turn toward topics I am now finding most engaging:
- Website security and related configurations and precautions,
- Website management, and
- Website design, at which I claim, for obvious reasons, basic
competence but no particular artistic ability.
When exploring new territory, I enjoy writing about discoveries because it
forces me to understand them better, and the result might help others.
