"Attempting to understand the retrograde motion of the planets [reconciling that with the Platonic notion that the stars were on a celestial sphere] was the principle problem in astronomy for nearly 2000 years."

@JWilliams this point:
"ISPs do not replace equipment on a customer’s property when that equipment is no longer supported by the manufacturer or vendor."
...was a big reason why I went from using a Linux-based Actiontec FIOS router that hadn't seen any available updates in years to using OpenBSD-based firewalls and routers at the network border.
