Old_Man_Phil

I'm a retired professor of software and systems engineering, an author, tinkerer, and lifelong martial artist. I have a unique perspective, and I want to share that with the world. My offerings reflect my quirky interests and tastes. I hope they don't offend you, but if they do, then don't buy anything. Or better yet, buy everything and burn them ceremoniously. I am also a published author. Check out my Amazon author page https://amazon.com/author/philliplaplante
