Lisp & physics
I am new to Lisp so forgive me if this question is very noobish, but is Lisp and/or the functional paradigm a good way to implement a large physics system. Like a simulation engine ect. Especially if real time results are important. One reason why i ask this question is because since hardware is becoming incresingl... 21 Oct 2006 09:20

Change function parameter from inside the function
Hi, Is there a way to change a parameter to a function in the body of the function? For instance, I have this function (defun add-to-population (rs1 population) (adjoin rs1 population :test #'equal) ) That I use this way (setq current-population (add-to-population result current-population)) But sin... 5 Oct 2006 17:00

Emacs's Command Frequency and default keyboard shortcuts
Here's a visual layout of the default keybinds in emacs: http://xahlee.org/emacs/emacs_kb_shortcuts.html A important aspect in designing default keyboard shortcuts is have kb shortcuts for the most frequently used commands, and, the top most frequently used commands should have most easily-pressed keystrokes. Fo... 21 Oct 2006 18:12

a potential lisp convert, and interpreting the shootout
hi, i am writing to get an idea whether lisp would be useful. so far, i think it would be ideal as a mode of expression, but i'm not sure whether it has (or i would be able to write) memory efficient or sufficiently fast code with it. i have zero lisp experience. i started with perl, then c++, then o'caml. ... 9 Oct 2006 21:22

Pocket Lisp Machine
I have an application that needs lisp and some stealth[1]. Recently I've been looking at TI calculators, since they have some interesting specs, in this case a 68000 processor, the same as in early Macs. http://en.wikipedia.org/wiki/TI-89_series Since I'm willing to trash all the calculator side in favor of ge... 28 Sep 2006 09:13

Redoing Matlisp?
Greetings! I'm thinking of reworking / redoing Matlisp to support a whole framework for optimized linear algebra that exploits the BLAS and LAPACK. Here are some features that I'd like to see: 1. Matrix views (like in the GSL) -- handy for the recursively-structured approach to linear algebra that's popular ... 25 Sep 2006 23:38
