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, How-to articles on topics including website security, management,
design, and safer web surfing, and a variety of online calculators. I've also published Microsoft Access
databases,
Excel spreadsheets,
and Word documents, templates,
and macros. 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 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.
The journey into the world of computers is a never-ending adventure of
exciting discoveries and new things to learn. My recent articles take a turn toward the topics I
now find 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.
Where To Start
