Add a path to the global $PATH with Ansible

When building certain roles or playbooks, I often need to add a new directory to the global system-wide $PATH so automation tools, users, or scripts will be able to find other scripts or binaries they need to run. Just today I did this yet again for my geerlingguy.ruby Ansible role, and I thought I should document how I do it here—mostly so I have an easy searchable reference for it the next time I have to do this and want a copy-paste example!

    - name: Add another bin dir to system-wide $PATH.
        dest: /etc/profile.d/
        content: 'PATH=$PATH:{{ my_custom_path_var }}'

In this case, my_custom_path_var would refer to the path you want added to the system-wide $PATH. Now, on next login, you should see your custom path when you echo $PATH!

Problems copying a huge Aperture library from one drive to another

I've often had trouble copying files with Mac OS X's Finder. From back in the Mac OS X Beta days (when it was based on NeXT's UI), hard drive to hard drive copies, network copies, and backups have often had strange quirks, and one of the strangest I've yet found happened yesterday when I tried copying a ~170GB Aperture library from one external USB drive to another.

I tried copying the library three times, and each time the copy would get to about 24GB, the hard drive (from which the library was being copied) would make a loud CLICK, and then it would unmount and remount, stopping the library file copy. This particular drive has never had troubles in the past, and the fact that it kept doing the CLICK-die thing at 24GB meant that there may have been a file problem or a Finder bug causing the problem.

I verified the drive using Disk Utility (could've gone deeper and used other utilities too), but only found one or two small errors (a file count one file off, or a few improper permissions). After repairing the disk, the drive still clicked off at 24GB.
