Tips

GMail, when accessed via IMAP tends to do some "interesting" things. There are several settings that lessen the pain:

1 - Click on, 'Settings,' at the top of the GMail web page while you're signed in. Click on "Forwarding and POP/IMAP" and then scroll down to the "IMAP" section.

2 - Update the following settings:
"When I mark a message in IMAP as deleted" - Auto-Expunge off
"When a message is marked as deleted and expunged from the last visible IMAP folder" - Immediately delete the message forever
"Folder Size Limits" - leave as default

For everyone getting ready to rid themselves of an iPhone (for whatever reason), please remember: inside the iPhone is simple flash memory. This memory is fairly recoverable, even when a restore is run to "wipe" the contents. WIth the ability to "jailbreak" an iPhone and access the filesystem, the problem of leaving sensitive data on the device becomes a little more problematic.

At this stage, I'd recommend waiting until the version 2 software ships and seeing if there's a true secure wipe before flipping a used iPhone.

As tends to happen between milestone releases, utilities get changed in oh-so-subtle ways. This time, sort broke for me. That's right, sort! Of the things...

10.4 sort accepted the "plus notation" for denoting the position of the key that you wanted to sort on:

ls -l | sprt +5

(OK, terrible example as you can do this completely with ls itself, but, you get the idea).

In OS 10.5, that is gone, and you need the more formal "-k" switch:

ls -l | sort -k 4

Note that the plus notation is zero-based, and the k switch starts at 1.

Be aware!

Ah..."syslog -w" also now dumps the last 7 lines of the file. That's a nice touch and improvement over Tiger, which showed nothing until new entries were added to the asl database. Thanks to whichever engineer took care of that!

OS X Server has used Kerberos as a single sign-on technology for some time now.  It's rare, though, to find a Kerberos server on a workstation, but that's precisely what you'll find on each and every OS X v10.5 workstation.  Single sign-on with no infrastructure.  Very, very cool.  However, it's not really documented very well.  Apple just put this kb article on-line, though:

Here's hoping to further implementation details!
