Apple Adds Memory Randomization To Leopard

.mack notes a ZDNet blog outlining some of the security features added to OSX Leopard (10.5). Here's Apple's brief description of all 11 new security features. "Apple has announced plans to add code-scrambling diversity to Mac OS X Leopard, a move aimed at making the operating system more resilient to virus and worm attacks. The security technology, known as ASLR (address space layout randomization), randomly arranges the positions of key data areas to prevent malware authors from predicting target addresses. Another new feature coming in Leopard is Sandboxing (systrace), which limits an application's access to the system by enforcing access policies for system calls."

Cool, but even better...

From the changelog:

CalDAV Group Scheduling
Schedule a meeting with colleagues, check availability, and book conference rooms when using iCal with a compatible CalDAV server like iCal Server.

Reserve Rooms and Equipment
Reserve meeting rooms and equipment as you create your meeting invitations. If your calendar is administered through a CalDAV server, iCal automatically displays availabilities when you add a room or resource to your meeting.

It sounds like a high-level player finally decided to take on Exchange. My biggest questions: are there Windows programs that support these features via CalDAV, and is there a CalDAV server in FreeBSD's ports?

When I first started using Quark XPress 6.5 in Mac OS X here at my new job, it took a while to work out the kinks for a rather complex project (doing layout for a journal w/ a 24 hr. turn-around), to the point that I actually put up a ``crash log'' outside of my cubicle, so that people could gauge my mood before entering. It's been a year now, and while I've gotten the project in question worked out (had to train myself _never_ to undo re-sizing a text box &c.), the totals might be interesting to people:

2006:
Quark XPress: 207 crashes (as many as 9 per day)
Adobe Illustrator: 25
InDesign: 35
PhotoShop: 15
Acrobat: 65
Microsoft Word: 23
Macromedia FreeHand: 9
Mac OS X: 14 (this includes Mac OS X apps like Mail.app and Safari.app)

The totals for this year are a bit more reasonable --- Quark XPress v6.5: 26, v7: 46 (I had to move the afore-mentioned journal over to Quark 7 after a re-design and that involved a new set of things to work-around) --- but I find Mac OS X overall reliable and workable as an environment (thought not as nice, consistent and synergistic as NeXTstep).
