If you need to tinker with your Mac, clear logs or caches etc. Rather than sudo'ing in Terminal, give Onyx a try, seems pretty good for a free application.

Exchange 2010 public folders
If you are trying to replicate content from 2007 to 2010, prepare for some pain. It just doesn't seem to work very consistently.
From Exchange Management Shell on 2007, go to the Exchange/Scripts folder and run:
.\AddReplicaToPFRecursive.ps1 –server my2007server –TopPublicFolder “\” –ServertoAdd
my2010server
This should add all the folder structure to the new 2010 PF database.
Once this is done, run the following to kick the process:

Once this is done, run the following to kick the process:
Get-publicfolder –identity “\” –recurse |update-publicfolder –server my2007server
You can check on the progress by running the Exchange Management Shell on 2010 and running:
Get-publicfolderstatistics
You might have to keep kicking it though as sometimes it just stops working.

New MacBook Pros
Well, I'm now sold on Macs. Got myself an iMac and I actually get work done now, instead of booting up and fixing a Windows problem every time. Still use Win 7 though as its not too bad, but OSX seems to always do the job.

There is also a nice crossover with Linux, so it satisfies the geek in me...

Configure Open SSH securely
Modify config in /etc/ssh or ssh_config to disable support for legacy protocols. Look for the 'Protocol 2,1' line and remove the ver 1 protocol.
Also set 'PermitRootLogin no' and 'MaxAuthTries 3'
After the changes have been made run:
service ssh restart
View attack activity by looking at /var/log/auth. If you see a particular IP that keeps attacking, put an entry in /etc/hosts.deny
You can automate this process by installing the DenyHosts package. Edit it's config in /etc/denyhosts.conf and change DENY_THRESHOLD_INVALID from 5 to 2
