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.
