comment Why do I get files like ._foo in my tarball on OS X?
I have GNU tar 1.15.1 by default on MacOS X 10.5.8 (Leopard). The latest version from GNU is 1.22 (March 2009). Downloaded and built: it does not appear to have '--no-xattrs' when built on MacOS X.

comment What constitutes a 'guest' account on Snow Leopard?
OK - it is an 'official' term. That helps a lot - and none of my accounts is a guest account within the meaning of that term.

comment Recursive chmod: rw for files, rwx for directories
Do you really want public write permission on files and directories? That means you don't care who clobbers any of the files?

comment How to install perl5.10 on OS X 10.5.8?
It depends which which you have as /usr/bin/which. The machines I used back in the late 80s didn't have any which in any system bin directory, which was a nuisance. Hence I cribbed this code. I added the -a, -r, -w, -x options relatively recently. If you've got a functional which, you don't need this one; if you don't, it may save you some grief.

comment Where does Mac OS X store file association information?
Yeah, but knowing how to change them also helps. Like it helped for me... @joshhunt: maybe if you made it explicit that the Get Info stuff is in the Finder with the file selected. (Just had to undo one application grabbing another's files - this helped.)
