C-ship: Exploring special relativity

Here’s what I’ve been doing the last week.  I’m not going to call this a Saturday night science post lest I find myself on a treadmill like at the other place, and besides it’s Sunday morning and before long the silly clock changing thing will kick in.  I’d hoped to wrap this up hours ago, but little did I expect that a bizarre confluence of IPv6, Gmail anti-spam filters, and obscure sendmail.cf configuration parameters would devour my entire day.
