Linux and Mac OS, how similar?

The way the US copyright system works is that by default the person or company that writes something owns the copyright to it by default. So unless Digital expressly put the source code in the public domain, that's impossible.

NT wasn't built from the ground up. It is VMS and OS/2 at the very heart of it.

And you know this because you've worked on both sets of source code?

Good friend of mine actually worked on the development team of Windows NT 3.1.

Reading white papers.

I was an active analyst in those days.

I am a developer who isn't easily moved by marketing hype.

Ever dig into early versions of Windows NT or OS/2? Even OS/2 hooks are in Windows NT 3.1. It's not rocket science.

Entertaining thread, this is.

The thing about writing a GNUStep/NeXTSTEP/OPENSTEP App and compiling it on OS X is something I was talking to one of my students about today. He had WindowMaker as his window manager on FreeBSD and was asking me about that (I happened to be using Interface Builder on OS X, which originally came from NeXTSTEP Interface Builder, and is also in GNUStep, and XCode, which is based on NeXTSTEP Project Builder). Unfortunately, since OS X has been out, Apple has been adding things to Cocoa that don't exist in the OPENSTEP API, so the cool things like CoreData and Cocoa Bindings, which take the pain out of writing Models and Controllers, can't be used if one wants to port to OPENSTEP.
