>I am pleased to announce on behalf of the authors of “Hacker’s Guide to Visual FoxPro” (Tamar Granor, Ted Roche, Della Martin, and me, with contributions from Steven Black) that the book is now open source: https://hackfox.github.io/.
>
>Most people consider HackFox to be the “bible” for VFP developers because it goes far beyond the VFP help and tells you how VFP really works. It advises which commands and functions to use, which to avoid, and the best way to accomplish certain tasks.

>HackFox has gotten a little long in the tooth since it wasn’t updated after VFP 7. Hopefully making it open source will allow it to flourish as people in our community update existing topics and add new topics for VFP 8 and 9. Also, the online content currently closely matches that of the book but that may change over time so it can become a better online resource.

That's really cool and a great gift to our community, thank you all.
