How do shift operators work in Java? [duplicate]
...t shifts the value 35 to the right two positions, which causes the two low-order bits to be lost, resulting again in a being set to 8.
int a = 35;
a = a >> 2; // a still contains 8
Looking at the same operation in binary shows more clearly how this happens:
00100011 35 >> 2

Rails 3.1: Engine vs. Mountable App
... gem in Gemfile is enough for the parent app to inherit the models, routes etc. The engine routes are specified as:
# my_engine/config/routes.rb
