Apologies. Deepest even. Before anyone needs to chastise me I looked it up and OS X is more Next and other sources than Linux per se. Apparently Parallels on OS X will run Win and Lin, but the underlying OS is OS X and does not imply that ArcGIS would be stably emulated by a Linux machine emulating Win. Sorry. Hope not to have too terribly offended in my ignorance. Colin

Not to chastise you, but I wanted a definitive answer, so I turned to wikipedia (http://en.wikipedia.org/wiki/History_of_Mac_OS_X#Development_outside_of_Appl...): "NeXTSTEP was based on the Mach kernel and BSD, an implementation of Unix dating back to the 1970s. Perhaps more remarkably, it featured an object-oriented programming framework based on the Objective-C language. This environment is known today in the Mac world as Cocoa. It also supported the innovative Enterprise Objects Framework database access layer and WebObjects application server development environment, among other notable features. All but abandoning the idea of an operating system, NeXT managed to maintain a business selling WebObjects and consulting services, but was never a commercial success. NeXTSTEP underwent an evolution into OPENSTEP which separated the object layers from the operating system below, allowing it to run with less modification on other platforms. OPENSTEP was, for a short time, adopted by Sun Microsystems. However, by this point, a number of other companies — notably Apple, IBM, Microsoft, and even Sun itself — were claiming they would soon be releasing similar object-oriented operating systems and development tools of their own. (Some of these efforts, such as Taligent, did not fully come to fruition; others, like Java, gained widespread adoption.) Following an announcement on December 20, 1996,[1] on February 4, 1997 Apple Computer acquired NeXT for $427 million, and used OPENSTEP as the basis for Mac OS X.[2] Traces of the NeXT software heritage can still be seen in Mac OS X. For example, in the Cocoa development environment, the Objective-C library classes have "NS" prefixes, and the HISTORY section of the manual page for the defaults command in Mac OS X straightforwardly states that the command "First appeared in NeXTStep."" So, yes, OS X is based on OPENSTEP, an evolution of NeXTSTEP. And it's based on BSD. And it's based on Mach. -- Rich
Colin, No need to apologize. It may help you to understand what Parallels does, though, so you can figure out whether it's appropriate for you. The first piece of information that may be helpful is that, while it was originally for the Mac, and its best supported platform is still the Mac, it can run on both Windows and Linux. What Parallels (and software like it) does is to create a virtual computer that can run on your currently installed OS. VMWare is (I think) the commercial pioneer in this field, and is perhaps still the most well known. What this means, in practice, though is that you are not really getting away from Windows, since you are actually running a full copy of windows in its own sandbox. Think of it as running a dual-boot machine, except that you don't have to reboot your native OS to start running the 'Virtual' one. The advantage of this is that you can run virtually *any* windows app (including most games ... although the performance can suffer) in your Linux (or NT/XP or Mac) machine. Generally speaking, however, this is not really a final solution for most people. You still are running windows, and as such must pay for the license and deal with the flakiness. It is sometimes a reasonable interim step when you have applications that simply do not play well (or at all) on Linux. There are also side-benefits with this sort of setup, involving easily saving and restoring configurations and operating environments, and from what I've seen of Parallels, the nested OS is still pretty responsive (this is in sharp contrast to the first time I ran VMWare about 7 years ago ... it was not fast, although it was *very* cool :) ) I hope that that is a (relatively) clear explanation of how that works. Feel free to e-mail me on or off list if you have any other questions. Cheers, Lee On Nov 17, 2007 10:59 PM, Colin Novick <c-novick-1@alumni.uchicago.edu> wrote:
