Re: ReadyLisp helpp

Hi Eric, I use AquaMacs and it seems totally fine. Are you sure it's not reading your ~/.emacs? Make sure you open that path in AquaMacs, just in case it's looking somewhere else (C-x C-f ~/.emacs). Lyrebird:disks oisin$ cat ~/.emacs (setq mac-function-modifier 'meta) (setq mac-option-modifier nil) ...

Re: The library situation (warning: mini-rant)

Hi guys, Thanks for your insightful and helpful responses! A few comments on your comments. Additionally, for distributing software to end users, if you are sending them a lisp image, it doesn't really matter how you got it to build. This is great news - I wasn't sure if this would work or not. If I...

The library situation (warning: mini-rant)

Hey, I decided to jump in and play with the libraries available in the CL community (i.e. ASDF-installable) to try to stop my procrastination in using CL. So I upgraded to the latest SBCL build for OS X and started looking for GUI libraries; something I personally expect from a programming language/...

Re: How to convert this Scheme code ?

Hi, the 'default' answer for a cond still needs an expression, which yours doesn't have. This works for me: (defun pair-pow (p n) (cond ((= n 1) p) ((evenp n) (let ((result (pair-pow p (truncate (/ n 2))))) (pair-multiply result result))) (t (let ((result (pair-pow p (truncate (/ n 2))))) (pair-mult...

Re: Lame topic - what about color themes?

The rod cells in your retina (those are the ones responsible for night vision) don't detect red light, so when you use a red light the cones take over and the rods stay adapted to darkness. Thanks Paul, nicely and concisely explained. I'll save up this information for trivia during a lull in some p...

Re: Lame topic - what about color themes?

Also from a night-vision-goggles thing. They use green so the light produced that you see is as dim as possible but still visible. Good point, although I heard that military use red lighting when dropping people from planes at night, because it allows them to read maps and such in the plane without...

Blue is the weakest in sensetivity.
Wow, I've never heard that before. Is it because we used to spend more time in forests and grass...? :P

Re: Graphics in SBCL

As a prospective SBCL user I would like to know what graphics facilities are available for (1) monitoring the progress of a long running program (eg in Genetic Programming) and also (2) for the more general situation of displaying program results (eg graphs and statistics, not animation). Hi, Just ...

Re: How to turn function into a list?

I may as well add that it seems to me that Lisp should have some kind of built in replacement for SQL also. Having this would get rid of another time waster in web app development, having to switch back and forth to the mysql command line. If such a thing doesn't exist, you could surely tack togeth...

Re: The Future of Lisp

Maybe someone should try it without any sort of optimizing algorithm. If massive mult-core is in the future, then I'd be interested to see how even a dumb implementation works. Agreed - if we assume optimising algorithms are too needy, some simple heuristics like this might be useful at least. How ...
