Linux Serial Programming Tutorial (iii)--serial port programming detailed Preface: This chapter will formally explain the serial port programming technology, uses a serial port to send and receive the data the procedure, comes step-by-step explanation. Note: You can download my source code for reference. Open serial Port As we all know, the device is in the form

This is the 16th article in the "Loose pair programming" series. (Pine pair Programming column directory) Today it's time to reuse a frame (asp.net MVC3, take the range including controller and view) and record the process. There are several features of the L-code structure compared to the general process of reuse: 1. If it is difficult to reuse, before reuse, generally do not deliberately form a "reusable

Asynchronous Programming in C # Processes and Threads The system creates a process in memory when the program is started. A process is a collection of resources required for a program to run, including virtual address space, file handles, and what other programs need to run. Inside the process, the system creates a kernel object called a thread that represents the program that is actually executed. When a thread is established, the system begins exe

transaction, InnoDB the default level. In the SQL standard, this isolation level eliminates non-repeatable reads, but there are also phantom reads* Serial Read (Serializable): Fully serialized read, each read requires a table-level shared lock, read and write each other will block Read uncommitted This level, the database is generally not used, and any operation is not locked, this is not discussed here. The default transaction isolation level for MySQL is repeatable read (repeated read). one,

Network programming is now a very common programming technology, network programming is nothing more than two or more devices (usually the computer) between the communication between each other, data transmission. The essence of the network programming is actually the communication between the program and the program,

Java programming 3-Are you suitable for learning programming? Author: Chen yuefeng from: http://blog.csdn.net/mailbomb programming is a technical live, so not suitable for all people. Now many people have heard of how well program designers are working to learn programs. In fact, this phenomenon is not normal, because the program is not necessarily suitable for y

Original ENGLISH: Competitive programming: How is competitive programming different from real-life programming? You have a knife in the jungle, and someone asks you to kill a puma. Anyone will ask, "What is a puma doing in the jungle ?!", Besides programmers. However, this is not what you are trained as a programmer to do. You should solve the problem here, rathe

Structured and object-oriented programming, Object-Oriented ProgrammingBytes The software development method refers to a variety of software development strategies proposed based on the characteristics of software development to design and implement high-quality software that meets user needs within the project investment scale and time limit. With the unbalanced development of computer software and hardware in 1960s, the development of large-scale so

Understanding of JAVA programming ideas and understanding of JAVA programming ideas1) POP -- Process-oriented programming ):Process-oriented programming is a functional-centered way of thinking and organizing. It emphasizes the process of processing and processing system data, in program design, the function or process

Dynamic programming (programming) is the mathematical method for solving the decision-making process (decision) optimization. Its name and dynamics are not related, Richard Bellman for bluffing.Dynamic programming is mainly used to solve the optimization problem with overlapping sub-problems, and its basic strategy is to decompose the original problem into simila

The development of computers has prompted the emergence of a new profession, and the procedural ape is a profession which has been in recent years and has been widely concerned, and it is believed that it is also a professional dream of many students. But the ape of the program also has very many, not every program ape can master all programming language. The so-called surgery industry has specialized, assume the future in the

A simple way to understand the object-oriented programming of PHP, PHP object-oriented programming Unlike most object-oriented programming languages, PHP supports both process-oriented and object-oriented programming, and PHP developers can freely choose one or the other in both the process-oriented and object-oriente

. Felleisen and others also pointed out this trend in "how to design a program". They said: "poor programming is very simple and dummies can learn it within 21 days, even if they are all wood!"Let's analyze what titles such as "learn C ++ in three days" mean:Learn: in three days, you have no time to complete some large programs, and you cannot learn from the successes and failures. You don't have time to work with an experienced programmer and get fam

Basic Concepts Extremeprogramming (XP) was proposed by kentbeck in 1996. Kent carefully observed and analyzed various prerequisites, feasibility, and difficulties for simplifying software development, and introduced this new concept of software development. Extreme Programming is born from a need to strengthen the communication between developers and users, allowing customers to fully participate in software development and design, and ensure that t

One day, a friend of mine who was learning to program asked me: "I want to quickly learn programming, do you have any good recommendations?" I taught myself to program when I was in college, and after all these years, I realized that I was probably in the hardest way to learn and understand programming. I could have learned at a faster pace. So, after reviewing the past, I wrote about some of the things I'v

Apue unix environment programming, unix environment programming Today, we have finally finished reading all the first 17 chapters of APUE. Basically, the main knowledge is in these chapters. After reading the "unix/linux Programming Practice tutorial", I felt very open and relaxed. At the code level, I learned many linux system mechanisms and never understood

If you insist on learning a programming language for 12 hours a day, every day in the year except to eat and sleep, Sarah is learning programming languages, such as learning Python (including databases, algorithms, and so on) every day to learn 12 hours a year down to what level of programming ability to achieve?

4. Lock-Performance Comparison and Analysis of lock-free programming and lock programming-Performance ComparisonA recently maintained network server encountered performance problems, so it made major changes to the original program framework. Most of the changes are the thread working mode and data transmission mode. The final result is to change the lock usage mode. After some improvement, the GMb Nic can
