We are deep into hard-disk crash trauma at CofFEE today with 2 volumes dying at the same time on Friday and a backup drive going down too. At least it was a sympathetic act on their behalf. Combine that with I lost a HDD on an iMAC after only 2 weeks since it was new a few weeks ago – after finally convincing myself that OS X was the way forward with virtual machines. Further another colleague’s back-up HDD crashed last week. It leaves one wondering what is going on. Backup is now a oft-spoken word around here today. But there is one thing I do know the answer to – Greg Mankiw’s latest Examination Question. It is a pity that he doesn’t know the answer himself. Further, it is a pity that one of the higher profiled “progressives” in the US buys into the same nonsense.
