based on scanning each message index file, determine whether the last message index in the file Messageoffset is smaller than the smallest messageoffset, if small, This indicates that the message index file is meaningless and can be deleted; Logic at broker startup Scan all the messages on the disk to store the files and establish a memory map for each file; Scans all the queues (message indexes) on the disk for storing files, establishing a memory map for each file; For e

instead of scrolling to the specified position and changing the position of the scroll, the cell that is not currently displayed is re-displayed in the location of the cell that will be displayed and then its contents are updated. The reason is that the cell structure layout in UITableView may be different, and it is undesirable to reposition it, but to reuse a cell that has already been created that is not already displayed on the interface. Of course, it sounds complicated, but it's easy to

First, in Reducer, the returned state must be a completely new object , otherwise redux will not execute the listening method, because Redux will assume that state has not been updated and there is no need to re-render the view.Examples of problems that occur:Const user= (state={name= ", age=0},action) = {switch( action.type) { case ' Change_name ': state.name= ' Zhangsan '; modifies the name return state in the original object ;

constructing data flowcharts: (1) external entities are generally marked only in the TOP flowchart and the first data flowchart. They do not need to be marked at other levels to highlight the key points and facilitate understanding; (2) Constructing the First-layer data flow chart is a key link. Follow the standard steps to grasp the main input and output links;

A possible implementation process is shown in: SOA project implementation process From the surface of several processes, there is nothing special about the implementation of the SOA

Today, I spent most of my time working with flash and flex3. I would like to summarize my experiences:1) if you use Embed to embed SWF, flex3 only supports SWF created by flashcs2.2) If it is loaded through loader, only the SWF of as3 can be controlled after loading (this is the opposite of the first point. It took me a long time to figure out these two points, khan !)3) To directly load data to flex, the class must inherit uicomponent, which is like

How to better software architecture design, this is a software engineering field of an eternal key topic. Over the past few decades, the International Software engineering community has made great strides in software architecture design, and a large number of books, articles and literatures record the mature experience and achievements in this field. Software architecture design is often a very complex work, involving a lot of details and aspects, can

With the development of China's routing industry, the routing protocol has become more perfect. Here we mainly explain the key points to be noted when selecting the RIP routing protocol. Another basic problem of the RIP routing protocol is, when selecting a path, it ignores the connection speed issue. For example, if a path composed of all fast Ethernet connections is a hop farther than a path containing a

For talents in any field, they started from the beginning. As time went on, they improved their technology and knowledge, however, for enterprise-level products-servers, IT administrators are required to learn, and new users are never familiar with them. With the breakthrough of each difficulty, they will become the top experts in the continuous development. For talents in any field, they started from the beginning. As time went on, they improved their technology and knowledge, however, for ente

Apache has always been the top three Web server software in the world. Enterprises need to comprehensively consider the security of their Web applications to ensure they can respond to network threats such as denial of service (DoS) attacks, traffic eavesdropping, and data leakage, this ensures the security of enterprise portal websites. In addition to the industry's popular firewalls, IDS/IPS Intrusion Detection Systems/intrusion defense systems), WAFWeb application firewalls), and UTM unified

File lock is one of the most common inter-process synchronization mechanisms in Linux. Compared with sysv semaphores, file locks are easier to use (the trouble of sysv semaphores lies in its key Acquisition Mechanism ).Apue provides a detailed description of the file lock. Note the following points. For the original article, see section 14.3 of apue2: 1. The file lock (file_lock) is bound to the file (speci

light Single-Mode Optical Fiber: optical fiber that transmits light forward without multiple reflections Frequency Division Multiplexing (OFDM): After a user allocates a certain frequency band, the user occupies this frequency band throughout the communication process. All users use different bandwidth resources at the same time. Time division multiplexing (TDM): divides the time into long time division multiplexing frames (TDM frames) such as segment.

In the near future, VoIP will become the main way for most enterprises to communicate. For CIOs, you must first understand the five key points of VoIP in enterprise applications. The comments of commercial technology practitioners on any emerging technology are divided into two parts. They will nod their heads and say, "Good, ......". IP-based Voice technology (VoIP) cannot be vulgar, and CIOs also like to

The 20 key points of PHP programming efficiency are to replace double quotation marks with single quotes to include strings, which is faster. Because PHP will search for variables in strings enclosed by double quotes, but not in single quotes. Note: Only echo can do this. it is a "function" that can treat multiple strings as parameters" Use single quotes instead of double quotes to include strings, which
