One of my greatest interest is programming. In this site, I try to cover some programming fields useful for beginners and mid-level programmers. I often came across similar examples in my work.

I did the best I could in designing modules familiar to me.  However,
instead of recreating some of these coding snippets from scratch, I decided to refer to some sites that I think are helpful.

I would like to thank the authors of these sites for creating concise programming summaries helpful to us all.
