Background: RAID is a Redundant Array composed of multiple low-cost disks. It appears as an independent large storage device in the operating system. RAID can give full play to the advantages of multiple hard disks, increase the speed of the hard disk, increase the capacity, and provide Fault Tolerance functions to ensure data security. In the case of any disk failure, you can continue to work, the disk will not be damaged. RAID can be divided into soft raid and hard raid. Generally, medium and

Cortex-M3 learning and debugging of stm32f10x UART In the process of learning the stm32f10x Development Board, the first learning routine is the UART Printing program. Due to the previous experience of single-chip microcomputer, UART programming is not unfamiliar, however, in order to lay a solid foundation for programming, the routine should be analyzed and introduced in detail, hoping to discuss with those who share common interests.1. stm32f10x UAR

Ti official website download stellarisware package, decompress by default path, in c: \ stellarisware has multiple folders, where C: \ stellarisware \ board \ rdk-s2e folder is the main character: source code for serial port to Ethernet. It uses lwip1.3.2 as the TCP/IP protocol stack. TI's serial port to Ethernet module can quickly convert serial transmission to Ethernet transmission. The module includes a microcontroller based on ARM cortex m3, a pai

byte in length, many other commands are 2 or 3 bytes in length. This is usually the case for a 16-bit architecture, where some commands may occupy 6 bytes or more memory.ARM Cortex-M3 and Cortex-M0 processor leverages ARM Thumb-2 technology that provides excellent code density. With Thumb-2 technology, the Cortex-M processor can support the fundamental foundation of 16-bit Thumb commands that have been extended to include more powerful 32-bit command

worth noting that"Dashboard"("Dashboard": IsWin8Task Manager performance tab, which isWin7Task Manager performance Tab Win8 optimizes the Task Manager performance selection graphics card on the interface, making it more fresh and intuitive. And renamed"Dashboard"("Dashboard") In the dashboard, You can intuitively display the running status of each CPU core (logical core, processor thread), as well as real-time monitoring of memory, hard disk, and network.

However, when configuring from the server, the added replication conditions cannot start the database; ho

I am using NXP cortex-m3 chip LPC1768 as the master chip, after repeated research and experiments, modify startup. the size of stack_size and heap_size in s Code does not help. However, there is a strange phenomenon, that is, the single-step debugging can only be executed once, and the results obtained this time are correct, then there will be a hardware error immediately and an endless loop of hardware errors will be entered into the assembly languag

The stm32-M3 has a system time base timer, which is a 24-bit descending counter. After the system time base timer is set and enabled, the counter is reduced by one every time the system goes through a clock cycle. When the counter is reduced to 0, the base timer automatically loads the initial value, continue to count down, and the internal COUNTFLAG flag will be set to trigger the interruption. The system time base timer function is simple, and only

This version of MySQL continues to improve the InnoDB Storage engine, mainly including: The InnoDB Storage engine is upgraded to version 1.1.1, which is also the latest development version. InnoDB uses a hash table to store redo logs during restoration. In 64-bit systems, the hash table size is 1/8 of the buffer pool size. To reduce memory usage, the size of the buffer pool for the hash table is adjusted to 1/64. If it is a 32-bit system, it is 1/128. In the slow query log, the Rows_examine

We have introduced some interceptor configurations and basic usage methods. So this time we will introduce the practical functions of the interceptor. The utility interceptor completes permission control. When a visitor needs to perform an operation, the application must first check whether the visitor is logged on and whether there are sufficient permissions

Do something before or after each request response. The interceptor here is similar to the interceptor of filter and struts. The main function of interceptor is to reduceCodeCoupling to provide code cohesion. Let's take a look at how the cxf interceptor works. 1. We will use the following helloworldservice and re-wri

The Struts2 Interceptor (Interceptor) is a very important concept, and most of the functions in STRUTS2 are implemented through interceptors. Here's how to implement the Interceptor in Struts2 and try to customize an interceptor. principle of Interceptor in 1 Struts2 Before

First, the principle analysisThere is nothing special about the interface definition of interceptor, except the Init and Destory methods, The Intercept method is the core approach to implement the entire interceptor mechanism. and the parameter actioninvocation it relies on is the action dispatcher.What needs to be pointed out here is a very important method of Invocation.invoke (). This is the method in Ac

Struts2 interceptor and struts2 interceptor 1. Why use interceptor? 2. interceptor PrincipleIt has three phases: 1. processing before executing the Action 2. call the invoke () method of ActionInvocation to forward the Controller to the interceptor or return the result stri

One, overview This article is mainly about how to customize the interceptor and through the custom interceptor to understand the interceptor lifecycle. Two, custom Interceptor 1) write an Interceptor class Hellointerceptor, which implements the

If you want to develop quickly, a simple and convenient web framework like Struts 2 is essential. We are using struts 1.2.8 to develop demos, and there is no El (expression language), resulting in countless pages that resemble " To get to the chase, Interceptor (the Interceptor) is a powerful tool for struts 2, and there are many features (feature) that are built on top of it, such as internationalization,

The Interceptor of Okhttp (Github:https://github.com/square/okhttp) is like the name "Interceptor", intercepting your Request to do something you want to do and send it out. For example:1. Automatically plus the user is currently using the language sent out to obtain the corresponding language content.2. Send the request to the sigunature of the request.In the okhttp, it is divided into application
