If you ever need to completely remove Xcode due to application issues or future upgrades, you can run a single command from Terminal to remove it.
sudo /Developer/Library/uninstall-devtools --mode=all
Of course, /Developer is dependant on where you installed Xcode to.
If you’ve ever faced that truly … testing … task of needing to remove a whole heap of hidden .svn directories from a folder and it’s myriad subfolders because some idiot did an SVN Checkout rather than Export to a development server, you’ll love this Terminal command:
find . -name .svn -print0 | xargs -0 rm -rf
You can run it from inside any folder to remove all .svn folders from it and all it’s child folders. Beautiful.
I recently purchased a DroboFS and one of the only hiccups I have had with it is getting it’s shares automounted properly under OS X 10.6.4. Surfing the net there is all kinds of lame-ass solutions such as adding the shares to the Login Items profiles, which works if your user gets automatically logged in on system boot, but then you get a Finder window that pops up. Rather annoying when other solutions are possible. Normally in past environments I would just add the share to the /etc/fstab file and you’d be cooking with fire, but I wasn’t having any luck with this DroboFS.
