Well, duh.

Well, actually, a fair bit of the graphical code on OS X comes from the NeXT operating system and graphics library. The older MacOS code has slowly been dropped from the Mac OS over the years. (The classic Mac OS actually used a Pascal interface. The current Mac OS uses Objective C.) -- Thomas A. Russ, USC/Information Sciences Institute

But Lispworks are competing with a number of similar products of varying prices (all the way down to free). Price is not, never has been, and never will be determined solely by the effort that goes into making the thing you're selling. If Pascal can convince you that by using his libraries you'll increase your profits a gazillion times, then you'd be silly to refuse to pay because it costs more than Lispworks. Regards, Andy

Saying that Mac OS X is BSD is: 1. true 2. a counterexample to the claim that linux is trouncing BSD UNIX. The original claim was that linux was dominating BSD UNIX because of the GPL. The 5x web client numbers for Mac OS X show that non-GPL licensed UNIX (here, BSD, APSL) in fact has much greater numbers than GPL linux. Finally, the APSL requires that modifications to *covered code* (i.e., the APSL library or code you are using in your larger work) be open sourced if your larger work is distributed. You are not required to open source the whole larger work, something that the GPL *does* require, and the LGPL, like the APSL, does not. warmest regards, Ralph -- Raffael Cavallaro |
