I'd also recommend looking more closely at the Vecto package that you're using/emulating/etc. In particulary, the WITH-CANVAS macro sets the graphic state in a dynamic variable. Then, all of the functions called within the body of the WITH-CANVAS use the *GRAPHIC-STATE*. In your case, the WITH-PIE-C...

(defun all (f l) (let ((r (mapcar f l))) (eval `(and ,@r)))) I haven't read this whole thread, so I might be repeating something already mentioned. But, the every function has the advantage that it doesn't call the function f more times than it has to. To see the difference, think of how often #'ev...

Thank you all for the information. I suppose I did have my head on straight, I just
wasn't seeing a way around the log_n rebuilds of a tree or without a top-level setf
somewhere (unless I use the Erlang-ish tail-recursion trick).

I think an implementation may be allowed to fill its buffer during the open call if you open the file for reading. I would bet most don't bother. But, I doubt there is a reason they can't.

I can really see and feel the benefits of pure functional programming. I don't yet have my head around it enough to use it everywhere I want to though. Maybe I am off track early somewhere. As a toy example, pretend I am implementing a chat server. Somewhere, there will be a list of who is currently...

And, Mike? You're in a situation where you have a full server box or a big slice of one? or is it being served through some webhosting company?

Thanks,
Patrick

The FILE* buffers in user-space (your program). Any buffering that happens with the file descriptor (from fileno()) is in kernel-space (your operating system). You will run into trouble if your C code writes to the FILE* before you Lisp code is invoked without calling fflush() because there will be ...

I voted for ACL over PCL (although i like them both) for its style, exercises, and appendix B and D. Agreed about ACL over PCL (as long as I'm remembering right and Appendix B is the Lisp in Lisp section). Sadly, neither book address the pile of soup that is (loop ...). Each have a few examples. I'...

There are a ton listed here: http://www.cliki.net/Graphics%20Toolkit
I haven't tried any yet though so I can't really recommend. Also, I don't think http://common-lisp.net/project/cello is on the Cliki page, and it seems worth a peek.

Agreed. I am in Minneapolis. I would be interested in occasional get-togethers.
