I recommend you to find a newer book. Ruby had important changes from version 1.8 to 1.9, including new syntax.
A couple of things I can think of:
* This is valid syntax in 1.9 but not in 1.8: {a: 'value', b: 'value'}.
* This is a valid method definition in 1.9 but not in 1.8:
```
def method argument
# stuff
end
```
