Pricing ACL I wrote this as an email reply to R. Fateman, but I now feel like posting it. (BTW, Richard, you probably meant to post your message in the first place): All I can say is that "we will ask you for a %-age of your future profit once you have your product ready for shipping" is a total deal breaker. I don't w... 26 Dec 2005 00:23
Newlisp? Anyone here used Newlisp (www.newlisp.org)? What's your impression? rg ... 23 Oct 2005 22:20
Continuation paper At ICFP 2005 Greg Pettyjohn presented a paper that he co-wrote with John Clements, Shriram Krishnamurthi, Matthias Felleisen, and myself that shows how to implement first-class continuations without requiring full stack inspection. The paper describes how one might implement first-class continuations in Java or C#... 5 Oct 2005 21:19
Koch figures Hi! Again with a simple code ;) It's about plotting Koch figures (curve, snowflake... and more!). (http://en.wikipedia.org/wiki/Koch_curve). I did a search in c.l.l., but didn't find anything. Maybe too simple? Anyway, I must confess that I am *very* *proud* of it! :P Really... I just wanted to draw the Koc... 30 Sep 2005 18:17
How to xor? I'm looking for a XOR to use like I use AND and OR. But the only things I found in the CLHS are: BIT-XOR, which works on bit arrays BOOLE-XOR, which, when used with BOOLE, works on integers LOG-XOR, which works on integers CLisp seems to have XOR, but CMUCL and SBCL don't. Isn't there some standard f... 24 Jul 2005 10:34
Lisp and Web Programming A friend asks: "Hi, I am trying to write a simple web application in Common Lisp. The first problem was to interact with a database server. Thanks to Haldun Bayhantopcu's help, it is OK using CMUCL + CommonSQL. The second problem is that CommonSQL has support for only few Common Lisp interpreters and comp... 17 Jun 2005 02:21
Fas->Lsp Decompiler Project Hi, I start writting a Fas-Decompiler for AutoCAD Lisp files. http://lisp-decompiler-project.cjb.net I think half of the work is already done. It's of some use in its current form.I'd worked out the specification of the Fas-file-format / how to decrypted & interpret the Fas-Bytecode. So for ex. the output ... 24 May 2005 16:04
Evaulate an arithmetic expression Hi all, I am writing a program to take derivative of a function and evaluate if given a value. "deriv" is the function to do symbolic derivatives, the signiture is defun deriv (expr var) and the function take derivative of expr with respect to var. so if I do (deriv '(* x x) 'x), it returns (+ x x). (Same a... 14 Feb 2005 20:28 |
