[quote="Jasper"]I guess we got to give them that, yes..[quote="Jasper"] No, actually we don't. But to understand why you need to understand a bit of history about XML that has been swept under the rug. Before there was XML there was SGML. It was meant as a meta-markup language fo...

I'd like to give some resistance to the libertarian-ness of the internet tragedy of the commons . Unless I misunderstand you, I'd like to "give some resistance" to your misunderstanding of the term "libertarian." There are a lot of kinds of libertarian, including some faux liber...

Nobody. :) Yeah, some people hear Paul Graham if they hang out on the right kind of web site. So non-Lispers are either hearing the occasional praise from some super-hacker they've never met, or nothing at all. Where's the common man in the Common Lisp world? Keeping his head down, or nonexistent, ...

I don't know about that. For every outspoken Lisp advocate, I think there are many more Lispers who hesitate to speak up for fear of overselling it. OK, but let's think about that for a second. Who gets heard? I mean- no disrespect to Graham, cause I love him to death, but... he's loud. Every time ...

I was wondering what is the best way to achieve a strand of "DNA" to use in a GA. I was thinking about these options: ((013) (201)...) ((0 1 3) (2 0 1)...) or an array (which I do not know how to make) Note: Duncan is right (I think) the leading zeros should not matter (but maybe they do)...

Reading this thread there's a lot in it I'd like to respond to, but I'm not known for brevity in any case, and if I tried to respond to all of it I'd wind up writing something way too long to read. But... First off I agree with findinglisp that Lispers ought not to gloss over the problems with CL. C...

Thanks for your answer! I'll look more deeply at the intern documentation for future reference, but stick with the 3 functions. I suppose that if it was so hard to make it work with macros (although I'm a beginner, 3 hours with no success for something so short seems too much) it's because it wasn'...

Now, I'm having a lot of trouble getting it done. The problem is that I can't see a way to access the symbol name (the 'x' in this case) and later use it as a keyword parameter for the make-3d-point function (as ':x'). Is there a way to do something like that? I tried: (intern (concatenate 'string ...

I'd third ppcre. Another thing that's worth considering is that most CL implementations are largely written in CL (which can get pretty hairy in cases where the origins of the system are hidden under a lot of years of bootstrapping- CMUCL comes to mind). So you might find it interesting to look at h...

The Structure and Implementation of Computer Programs is also very nice as an introduction to programming (via Scheme). First chapters of Paradigms of Artificial Intelligence Programming can be used as a Common Lisp textbook with exercises. And of cource, as I started to learn Common Lisp through A...
