Interesting how much it majors on Open source-ness ( given the way Apple
closed up post move to intel)



e.g.


"Xray

Xray is a brand-new, timeline-based performance visualization tool that
gives you the ability to see how your application works like you’ve never
been able to do before. It let’s you watch CPU, disk I/O, memory usage,
garbage collection, events, and more in the form of graphs tied to time.

For example, you can track UI events in real-time and see how they affect
I/O activity and CPU load at the same time. And, once the data has been
collected, you can scan back and forth through your application’s run and
see exactly what occurred, and when."

Blimey that's impressive but wait....

"Xray builds on top of the open source DTrace utility. DTrace is a
comprehensive command-line monitoring utility that can probe almost any
aspect of system performance. It comes with a large set of tools that cover
most general aspects of system performance, including both kernel and user
code, with near-zero overhead. If there is an aspect of the system that you
want to track that isn’t already supported, you can create your own tool
using the D programming language."

So thanks to the DTrace ppl...

& then..

"OS Foundations

The heart of Mac OS X, the Open Source Mach- and BSD-based UNIX layer known
as Darwin, continues to see improvements in Leopard. The latest Mac
hardware brings more processing power, more cores, and more memory than
ever before. The kernel in Leopard has been updated to take advantage of
this new hardware.

Leopard certainly won’t be UNIX in name only. Apple will submit Leopard and
Leopard Server to The Open Group for certification against the UNIX ‘03
product standard."

But wait there's more..

"Leopard brings several new security enhancements to Mac OS X. The
first of these is the adoption of the Mandatory Access Control (MAC)
framework. This framework, original developed for TrustedBSD, provides a
fine-grained security architecture for controlling the execution of
processes at the kernel level. This enables sandboxing support in Leopard.
By sandboxing an application, using a text profile, you can limit an
application to being able to just access only the system features, such as
disk or the network, that you permit."

& then:

"Open Directory 4

Leopard Server ships with an updated version of Open Directory that
supports LDAP proxying, cross-domain authorization, cascading replication,
and replica sets. It even supports RADIUS authentication for AirPort base
stations deployed across your office or campus. "

&

"Ruby on Rails

Leopard Server features a built-in installation of the powerful and
productive Ruby on Rails web application framework. Ruby on Rails is a full
stack framework optimized for sustainable productivity. Leopard Server will
ship with Mongrel for simplified development and deployment of web-based
applications."

Reminds me of a SCO Presentation.
