Tap on one of your contacts, and you'll see a beautifully designed page that offers quick access to call or message the contact on various platforms. It'll show the last messages between you two, share location, weather updates, and the time for their area, and you can add notes if you want to remember specific things. You can access this the same way you add a widget; it sits under the Contacts app. Notifications from these contacts are prioritized.，更多细节参见PDF资料

Dynamic: Pulling is always dynamic, as we discussed before. But because we don’t need any global ordering of nodes, it’s very easy to have a dynamic push step as well, as each node only needs to keep a list of its upstream and downstream immediate neighbours. This structure is typically much easier to manipulate than maintaining a globally ordered list (and a lot cheaper than performing a fresh topological sort every time we want to evaluate nodes).
a practical poisoning attack.
