I'd love to hear any feedback you have about this site, my book, or just programming in general. I can be contacted by email at: LV@codeplea.com
If you have direct feedback about the code in my book, and you use GitHub, you might consider communicating via a GitHub issue. You can access the code GitHub repository using the link at the very bottom of this page.
I'm also currently available for consulting work. If you have a project you think I could help with, please don't hesitate to reach out.
