Sync a Shared Google Calendar with macOS, OS X, iOS (iPhone, iPad), or CalDav

2018 Update: Sadly, this is still the correct way to get syncing working.
2019 Update: Still true.
2020 Update: Sigh.

Someone shared a Google Calendar with me recently, and it showed up at calendar.google.com just fine. However, I could not see the shared events on my Mac (using Calendar) or on my iPhone or iPad (using the Calendar app).

To fix this, I had to visit https://www.google.com/calendar/syncselect directly, and check the shared calendar, then save the settings.

I'm posting this here because after spending an hour or so digging around all the Google Calendar settings online and settings on my Mac and iPhone, I finally found that link in some random forum post (nowhere to be found in Google's help docs!), and I don't want to forget how to manage shared calendar sync! Even using the iCal feed for the shared calendar didn't work.

Vagrant - NFS shared folders for Mac/Linux hosts, Samba shares for Windows

[Edit: I'm not using rsync shared folders (a new feature in 1.5+) instead of SMB/NFS - please see this post for more info: rsync in Vagrant 1.5 improves file performance and Windows usage].

[Edit 2: Some people have reported success using the vagrant-winnfsd plugin to use NFS in Windows.]

I've been using Vagrant to provision local development and testing VMs for a couple years, and on my Mac, NFS shared folders (which are supported natively by VirtualBox) work great; they're many, many times faster than native shared folders. To set up an NFS share in your Vagrantfile, just make sure the nfs-utils package is installed on the managed VM, and add the following:

<br />
    config.vm.synced_folder "~/Sites/shared", "/shared",<br />
      :nfs =&gt; !is_windows,<br />
      id: "shared"<br />

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.
