As a few other people here mentioned, I'm creating a FreePascal edition of my ancient Turbo Pascal book, ripping out stuff that nobody needs anymore, like CGA graphics and TurboVision. (I believe that there's a Turbo Vision clone available for FreePascal, but I just can't force myself to learn it again and write about it, even though I was writing paying apps with it in 1993.) The book is free, and the current version (I tinker with it irregularly) can be found here:

I'm going to stop building the release date into the filename with the next release; just search for "FreePascal SquareOne.pdf".
I'm programming almost exclusively in Lazarus these days, a lot of it for the Raspberry Pi. At some point I'd like to write a couple of shortish books on specific Lazarus topics like databases, and once we get settled in Phoenix I'll give it a try.
BTW, my friend erbo told me about this thread, so I figured I'd stop in and say hi.
