In 2007 I wrote a regular expression engine that I called wregex. I’ve now cleaned up the code and placed it on GitHub.

This essay is a description of how it is implemented. I think that if you understand the concepts you will never be puzzled by a pattern again.

I thought it is about time to write something about my library of C functions for manipulating bitmap images. It has been with me for many years and I’ve used it in a lot of my hobby projects.

I recently posted an entry on my Jatalog project, which is a Java implementation of the Datalog deductive database system. I thought I could elaborate on why I created it.

The source code for Jatalog is available on GitHub.

I originally published the article below on CodeProject in July 2016. I’ve been meaning to republish it on my personal blog for completeness, but haven’t come around to doing it until now.
