Developing Large Web Applications

Colophon

The animal on the cover of Developing Large Web Applications is a Newfoundland. Also known as a “Newf” or “Newfie,” this massive dog is 26–28 inches tall at the shoulder and weighs 100–150 pounds. As its name implies, it originated in Newfoundland, Canada, where it was used by fishermen to haul nets, carry boat lines to shore, and retrieve items that fell overboard. An agile swimmer, the Newfoundland has webbed feet and a water-resistant coat, which can be black, brown, gray, or white and black (Landseer).

Newfoundlands are “gentle giants” known for their sweet, loyal dispositions and obedience to their masters. They rarely bark, but are protective when necessary. They are generally very good with children and other animals. They are well suited for apartment dwellers, as they tend to be relatively inactive indoors; for exercise, a daily walk is usually sufficient, though they do enjoy opportunities to play and swim. In keeping with their heritage, Newfoundlands prefer colder climates and do not do well in hot weather; they should never be left in the heat without water and shade. They are prone to certain health problems, including hip and elbow dysplasia, cystinuria (a hereditary defect indicated by calculi stones in the kidney or bladder), and subvalvular aortic stenosis, a common heart defect that can cause sudden death at an early age. Their average life expectancy is 10 years.

Thanks to its muscular build and swimming prowess, the breed is frequently used in water rescues. ...
