For number crunching, SBCL is the best choice, as far as I know. It has good compiler that optimizes away a lot of overhead (mostly because SBCL does fair amount of static analysis of code including type inference) and (with proper declarations) can approach the level of hand-written C code. The bes...

The easy way is to use DRAKMA.

Code: Select all

(drakma:http-request uri)

will return you a string (http-request has _a lot_ of options, it can return not just strings).

Some function grovels over all folders, collection *.asd and adding each folder that has a *.asd on the asdf:*central-registry*. It is possible to write custom system-definition search function (function that takes system name and returns the file), and then push it into asdf:*system-definition-sea...

As an idea for a secure interpreter, how about create a checking program/function/macro that checks to see if the submitted code contains any 'non-secure' function/macro calls? That might :?: be easier than trying to saw off big chunks of lisp. How about that? (let ((x "SOME-UNAUTHORIZED-FUNCT...

I know I can use the coerce function to make a list from a given array, However, when I give it a multidimensional array I get a list of all elements. Is there any "easy way" to get ((1 2) (3 4)) from #((1 2) (3 4))? Thanks in advance. ;) You can use :initial-contents keyword argument for...

There is a simpler way to get the data out of wikipedia: 1) There are dumps of database available for download at http://download.wikimedia.org/ . You can import them into database and query the database. As a benefit, it will be simpler to parse, because text is in wiki markup, not in html markup 2...

You could use http://www.weitz.de/drakma/ . Example: (defvar *wiki-main-page* (drakma:http-request "http://en.wikipedia.org/")) (subseq *wiki-main-page 0 1000) => "<!DOCTYPE html PUBLIC \"-//W3C//DTD XHTML 1.0 Transitional//EN\" \"http://www.w3.org/TR/xhtml1/DTD/xhtml1-...

Does anyone here know enough about C# and LINQ to know whether the syntactic sugar that they added was something that anyone could add in their own back yard (a la using Lisp macros), or whether the C# designers had to add it as a specific new feature in the C# compiler? LINQ is a compiler feature....

Write it like this:

Code: Select all

(defun it (n &rest values)
  (loop
     for y in values
     repeat n
     do (print y)))
