25 Years of Programming Home
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. 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, Word, and Excel projects, are useful.
- Some are entertaining.
- Some demonstrate or discuss interesting mathematical or scientific principles such as machine learning, adaptation, evolution, complexity, 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, with any luck, will probably 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, the most recent additions take a turn toward topics that 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 might help others and it solidifies my own understanding, so these topics become How-To articles in the blog.
