I'm guessing the dependency is probably due to our

That's because floor isn't an intrinsic. The crippling speed issue was the fact that floor computed and returned at real precision. On recent (sandybridge?) CPU's, it was found that x87 does more ill than good. So I changed it to a template in Phobos (and did some nice tidy ups in the process). This will be pulled down in the 2.066 merge. Speed improvements were discussed in the PR and in the original pnoise thread. Though it's very likely that a hand optimised SSE3 assembly implementation in C's mathlib might still be faster. Iain.

Or an article about using a particular library that's written for D?

What about tutorials? Allowed?

A general article on the language itself? An article related to D? I recently started writing an article on ranges in D, since there have been requests for a good article/tutorial on ranges. Would that qualify? Or are you looking for something else? - Jonathan M Davis

Re: D Article Contest - win an iPad2
Very nice initiative. D needs more articles and publicity. Hopefully many people will write articles even if they are know they are not able to compete for the grand prize - an article written by me cannot compete with Andrei or Bartosz :) 2. Digital Mars may submit the article on your behalf to publishers like DDJ and Artima.com Where would the articles that's not quite up to that quality standard go? codeproject.com? digitalmars.com? d-programming-language.org?
