This is a creation in Article, where the information may have evolved or changed. NSQ is a distributed real-time messaging platform based on the Go language, which is based on the MIT Open Source protocol, which is hosted on GitHub and is currently the latest version of the 0.3.1 version. NSQ can be used for real-time messaging services in large-scale systems and can handle hundreds of millions of levels of

object whose value will change). In addition, the receiver also needs to know the life cycle of the sender, because the viewer's registration needs to be canceled before the sender object is destroyed. If both requirements are met, the message can be 1-to-many during messaging (multiple observers can register values in an object). If you plan to use KVO on the core data object, you need to know that this is a bit different from the general KVO usage.

Recently, due to work relationships, we need to push messages to customers on the Android mobile phone platform. The original push technology on the Android mobile phone platform uses c2dm (cloud to device messaging framework ), however, this year, Google announced its end of support and development and its acceptance of new user registration. Google then officially launched GCM (Google cloud messaging) to

Due to the power-saving and memory management strategies, the manufacturers based on their own understanding, in the self room published in the standard Android release as a more or less changes, so that the application layer program in the processing process and service keepalive problem is very complex, and difficult to compatible, Because there might be a change in which phone or version of the power-s

1. The Android asynchronous messaging mechanism has the following two ways: (Asynchronous message delivery to resolve thread communication problems)Handler and Asynctask2, the use of handler official interpretation:1), timed tasks: Use Handler.postdelay (Runnable R, time) to execute MSG at specified times.2), inter-thread communication: Perform time-consuming tasks in a child thread when performing a more time-consuming operation, and then handler (th
