It's not always easy to develop a Web application, but in fact it's just a matter of mastering a few key principles-creating and connecting a socket, trying to connect, and sending and receiving data. The real difficulty is to write a network application that can accept fewer than one, and more than thousands of connections. This article discusses how to develop a highly scalable Winsock application on Windows NT and Windows 2000 through Winsock2. The main focus of the article is on the server s

provides a PHP program running environment. The server is transparent to developers and does not require developers to intervene in server management. 2. Server Load balancer System Server Load balancer systems are divided into hardware and software. Hardware load balancing is efficient, but expensive, such as F5. The software Server Load balancer system is cheaper or free of charge, and the efficiency is lower than that of the hardware Server Load balancer system. However, the software Server

SOURCE Link: Spark streaming: The upstart of large-scale streaming data processingSummary: Spark Streaming is the upstart of large-scale streaming data processing, which decomposes streaming calculations into a series of short batch jobs. This paper expounds the architecture and programming model of spark streaming, and analyzes its core technology with practice, and gives the concrete application scenario

The ViewPort Example:The width and height commands specify the logical width and height of the video area. Their values are either numbers in pixels or special markup symbols. The width command uses the device-width flag to indicate that the area width should be the screen width of the device. Similarly, the height command uses the device-height flag to indicate that the video height is the screen height of the device.The user-scalable command specifies whether the user can

Label:Today I encountered a very interesting problem with the number type scale, and I use a simple test case to illustrate this case. If there is a test table, there is a field type number, I insert the following two data CREATE TABLE TEST ( VARCHAR (12), QTY number ) into TEST SELECT ' M ' fromUNION All SELECT ' C ' from DUAL; COMMIT; Directly query the table test, found that the Qty field value is 1,When using the following SQL st

Cloud computing is not just a fast self-service service for virtual infrastructure. Developers and administrators are looking for ways to supply and manage large-scale cloud computing. This Infoq article is one of a series of automated tools and ideas for dynamic computing resource pool maintenance. You can subscribe to a new article in this series to post a notice here. The typical deployment of early cloud computing was that one or two employees us

It is believed that with the application architecture of the Internet technology being accepted by the traditional industry, object storage and Swift will be more and more widely concerned.From the OpenStack kilo version of the data, the swift community presents a diversity of features and is developing healthily.This article and the next two articles in this series will introduce the architecture of Swift and give examples of scale deployment

Let's start with a 3 -part introduction:1. Scale(x, y) scales The elements X represents a multiple of horizontal Scaling | Y represents the zoom factor in the vertical direction Y is an optional parameter that is not set, which means that the zoom multiplier is the same for X, y two directions . and take x as the standard .

, Let all the records state back to the original state, when the car never came. The principle of this approach is to use the nature of the transaction rollback, the change of state and the fallback, which in the business system development also has a proprietary terminology is the workflow. In fact, most of the questions about how to implement distributed transactions is the essence of the problem is to solve the rollback of the transaction, we actually do not be the name of the distributed tra
