Sup John,

You'll like this, although it is a different flavor.

<h2><font color="#000099">FutureTech:</font> Why Unix is cool</h2>

<b>By Cameron Crotty</b><br>





<P>
Unix is about as far from the Macintosh way as you can get. It's obscure,
confusing, arcane and incredibly difficult to operate. Yet if you believe
the post-COMDEX news reports, Linux (the open-software flavor of Unix
masterminded by <A
HREF="http://macweek.zdnet.com/mactheknife/unkind/981103.html">Linus
Torvalds</A>) is poised to send Microsoft NT running with its tail
between its legs and usher in a new era of software free from the twin
shackles of corporate greed and Microsoft. Can an end to world hunger be
far behind?</P>

<P>
What you may not know is that Unix is coming soon to a Macintosh near
you. Behind all the hoopla surrounding Mac OS 8.5, Apple has been quietly
polishing Mac OS X Server, the first incarnation of the company's
next-generation operating system. The current conventional wisdom has
Apple releasing the product, formerly code-named Rhapsody, at January's
Macworld Expo in San Francisco. But the most important thing about this
particular package isn't when it arrives, it's what's inside.</P>

<P>
Deep down in the heart of Mac OS X is the <I>kernel</I> of the operating
system -- the irreducible core of software that interacts with the
microprocessor and other system hardware and handles all the low-level
system tasks. The Mac OS X kernel is a modified version of the Mach
kernel, designed by researchers at Carnegie-Mellon University. It's this
kernel that allows Apple's OS designers to build nifty bonuses like
pre-emptive multitasking and memory protection into Mac OS X. And its
streamlined design means that Apple has the opportunity to wring
previously unheard-of performance out of the PowerPC chip.</P>

<P>
But scratch the surface of the Mach kernel, and you'll find Unix
underneath. Mach is compatible with BSD 4.4 (a flavor of Unix), and the
developers intend for future versions to maintain that compatibility. In
fact, according to Apple's own <A
HREF="http://developer.apple.com/techpubs/macosxserver/macosxserver.html">Rhapsody
developer documentation</A>, many programs that operate under BSD 4.4
will operate under Mach without modification after being recompiled.</P>

<P>
This doesn't mean you're going to peel back the Finder of your Mac OS X
machine and find a command line-interface lurking just below the surface,
like a burial ground waiting to rise up in the middle of a bunch of
suburban tract homes. People who want direct access to the Unix command
line will be able to get it, although it will be much easier under the
upcoming Mac OS X Server release than in future releases. For one thing,
Apple hasn't completely developed its Unix implementation (there are a
few APIs missing here and there). However, there is a small group of
users and companies eagerly looking forward to what Unix access Mac OS X
Server will have to offer. The rest of us will just have to enjoy the
speed and power of Unix with a plain old Mac interface.</P>
