This is a bit more advanced but I find it really useful. Open a terminal window and type in or copy paste the following and press enter:

defaults write com.apple.dock persistent-others -array-add '{ "tile-data" = { "list-type" = 1; }; "tile-type" = "recents-tile"; }'

Then type:

killall Dock

to restart your Dock. You will have a new stack item on your dock allowing you to access the ten most recent applications.

Where I work we’ve had a long standing problem with the roadmap view in Trac with the Agilo plugin. We were seeing a “ticket 0 does not exist error” and after finally finding the right keywords to search with, I found my answer. Turns out that if you’re using PostgreSQL as your database backend, any Sprints that have a ‘ in the name will cause the roadmap to stop working. The fix is to simply rename any Sprints so they don’t have a ‘ in their name.

Here’s something a lot of Linux users probably overlook. If you manually create a partition or file system on a new hard drive but you want mount during each boot you should mount the drive based on its label instead of it’s device name. This will prevent the system from mounting a drive in the wrong place if you ever switch cables around or move the drive to a different machine.

Labeling a partition is simple, just use e2label /dev/

e2label /dev/sdb1 "NewDrive"

To mount this drive on boot, edit your /etc/fstab file as root with your favorite editor. Add a new line at the bottom with, based on the example above, the following:

LABEL=NEWDRIVE /mountpoint defaults 0 0

You can use the other entries in the file as a template. Use ‘man fstab’ and ‘man e2label’ to learn more about how to use e2label.

This is a simple one. There are a number of menu bar items that aren’t easily accessed through system preferences that can be found in System -> Library -> CoreServices -> Menu Extras. Double click an interesting item that you find in that folder. To remove the menu bar item simply command drag the menu bar item away from the menu bar.
