For you to reflect the users of the live software to the detailed analysis of the price of small cucumber share.
Analytical sharing:
1, the user entered the gift list, found 1 cucumber = 1 Diamonds
2, then in the Recharge page 1 Yuan = 10 diamonds, that is 1 cucumber = 0.1 yuan, and if a single refill diamond more words can also be given the diamond, so the translation of the price of cucumber less than 1 cents, no wonder the number of cucumber gifts!
Okay, the above informatio

After multiple clients establish a connection to the server, the Socket.io () server has a sockets property value that is the socket object that establishes the connection to the client. You can use the Send method or the emit method of this object to broadcast messages to all clients.
Io.sockets.send ("User commected");
Io.socket.emit ("login", names);

In the Android version, in particular, the 4.1 introduced Mediacodec to encode the camera's image to achieve live broadcast.
The general Android push to the server, the use of ffmpeg mostly, that is, soft coding, in fact, the use of Android hardware coding will have a bett

I. Classification of communication methodsThere are three communication modes in the current network traffic: unicast, broadcast, and multicast (multicast), where multicasting occurs at the latest, with the advantages of unicast and broadcast.
Unicast: Communication between a single host and a single host
Broadcast: When a host communicates with all
Introduction to Android common components Broadcast, androidbroadcast
I. Introduction to Broadcast
Broadcast is one of the four main components of Android. It can be divided:
1. When a normal broadcast sends a broadcast, all the broadcas
The broadcast in 0.Android can be divided into two types, standard broadcast and ordered broadcast. Standard broadcast (normal broadcasts) is a fully asynchronous broadcast that, after broadcast, almost all
Time in a hurry, the blink of an eye is big half a month passed, learn the truth of Android hard and long Ah!! I wrote a lot of small demo, summary summary, but also in the blog to leave some footprints it!Source code Download: http://download.csdn.net/detail/harderxin/7761401 Reference example: Lao Luo blogImplementation function: Statistical count, we may have a lot of ways to achieve it, but this example uses activity, Service, Broadcastreceiver in Android three big knowledge points, so think
After a few blog, record the different interface between the common methods of value-transfer.This article records the way of broadcasting.In the design mode of iOS, the notification mode is also one of the important patterns.Notification literal translation for the notice, actually I think is called the broadcast mode more appropriate.It is a function of one object to synchronize the operation of multiple objects.The usage is simple, an object sends
Activity transmits data to the broadcast receiver simply by put the data into the intent before sending the broadcast.How does a broadcast receiver transmit data to the activity? The interface is used here, by defining an interface in the broadcast receiver, and then the activity that receives the broadcast receiver
1. Pay attention to the broadcast initiation action, and register the broadcast in the AndroidMainfest. xml file, and the broadcast needs to be filtered using intent-filter.
2. System-level broadcast: The call is the same. You only need to register the broadcast in the Andro
"TCP/IP Detailed Volume 1: Protocol" 12th chapter broadcast and multicast---reading notes1. IntroductionBroadcast and multicast are used only for UDP, and they are important for applications that need to transmit messages to multiple recipients simultaneously.Sometimes, a host sends frames to all other hosts on the web, which is the broadcast.Multicast (multicast) is between unicast and broadcast: frames ar
Conflict domains and broadcast domains of network interconnection devices (1)
A conflict domain refers to the minimum range of conflicts. When a computer and a computer are connected through a device, a channel is established. If this channel allows only one data packet to pass in an instant, if there are two or more data packets that want to pass through the packet here, there will be a conflict. The size of the conflict domain can be used to measur
circulation. For example, IPsec AH authentication is required for group circulation between host A and host B.
4. Three types of operations are supported.
Send messages to the kernel and open key management socket. You can request keys from the key management daemon.
You can read data from the key management socket and request a key management daemon to install a SA for a New TCP session protected by the policy.
Send a dump message.

From theory to practice (8): event broadcast
Three message exchange modes in WCF are discussed in the previous section: one-way, request/reply, and duplex. The first two items are relatively simple, and there is no need to talk about them. duplex is relatively complicated. The preceding section only implements simple callback. in actual application, there are many points worth noting, in this article, we will talk about the specific application of du
1. Introduction to unicast, multicast, and broadcast 1. 1. Unicast (unicast)
Unicast means data transmission to a specific host. For example, an IP packet is sent to a host. At this time, the data link layer is given in the Data header is very specific destination address, for Ethernet, is the nic mac address (not FF-FF-FF-FF-FF-FF such address ). The current host with the routing function should be able to distribute unicast data in a targeted manner
