Marty Abbott (TechSVP eBay): "[W]e would have potential vendors and partners come in and try to sell us on the idea of grid computing and we'd say, "It sounds an awful lot like what we were doing. We didn't know there was a name for it." — Thanks for the pointer, Gavin!

"Eighty percent of the site runs with Java within WebSphere."

"We believe the infrastructure we have today will allow us to scale nearly indefinitely."

"The next vision for this thing is to give the 450,000 people who make their living in whole or in part on eBay information from the data warehouse to help them understand what products are selling the best and what they should put more of on the site."

M:N relationships in Rails: has_and_belongs_to_many (nice!).

In contrast to Helma, the Rails model layer - Active Record - saves you from having to declare value mappings (title, firstName &c.) as well as from having to explicitly map join tables for m:n relations. Per default, table names are inferred by pluralizing class names: A class named Person is guessed to be backed by a table named persons.
