In OSX Mountain Lion I'm getting beeps every time a facebook notification comes in. In System Preferences > Notifications > Facebook i have set my alert style to None. In the list on the left, the text below "Facebook" shows "Badges, Sounds". It gives me no method of turning off Badges or Sounds.
An important thing to keep in mind when testing this is that some application have their own DNS cache. For example the Chrome browser: it doesn't make sense to lookup IP addresses on every page reload, if the IP of facebook.com was 126.96.36.199 a minute ago it should still be the same now, right? This makes it hard to test things, because it takes a couple of minutes for Chrome to expire its cache. Unless you know a method to expunge it.
Apple has also created their own version of Maps, which will surely put Google Maps to the test. With features like a 3D button, info cards for more than 100 million businesses, traffic services to tell you where there is an accident, turn-by-turn navigation, and re-routing you when you are stuck in traffic, Google needs to watch out. 2b1af7f3a8
