Concurrent Programming (1) ---- Concurrent Programming basics, ---- programming Basics Multithreading is a basic knowledge that programmers must master. However, due to the encapsulation of various frameworks, we seldom access multithreading. Once a problem occurs in the project, you cannot start. Multi-threading not only helps you better handle project problems,
I've been using Scala for a year or two, and the language seems to have a magical power that people don't want to let go of when they use it. Scala has had a very profound impact on my entire program life, and I learned about functional programming, so I know that there is an elegant, efficient, powerful language in the world.Scala is very popular abroad, but somehow it's always tepid at home, and I want to do something about the development of the la
What do you mean?The C language does not have a specific string type, but it can also handle strings. This article does not discuss the use of strings, but rather discusses the relationship between C strings. Title, in c language code, if define # define STR = "Programming", and then use printf ("%s", "Programming"), what do these two "programming" have in common

What is itBefore describing the difference and pros and cons, briefly introduce both.Functional programming, as the name suggests, this kind of programming is the function of thinking as the core, in this thinking angle to think about the problem. The most important foundation of this programming is the lambda calculus, which accepts functions as inputs and outpu
[Shell programming] 1. Introduction to shell programming and introduction to shell programming Shell itself is a program written in C language. It serves as a bridge for users to use Unix/Linux, and most of their work is done through Shell. Shell is both a command language and a programming language. As a command langu
Multi-thread programming, Java Network Programming, and multi-thread programming 1. Thread Overview There are two types of multi-task processing: process-based and thread-based (process refers to a self-contained running program with its own address space; A thread is a single sequential control flow in a process) The process-based feature allows the computer to

Introduction to asynchronous Task programming, Thread multi-Thread programming, and task multi-Thread programming When I was a beginner, I searched online. I saw many articles with titles related to replacing thread with tasks. I always thought that Task and thread are the same. In fact, task is. asynchronous programming
This article mainly introduces how PHP programming can improve programming efficiency (keep these 20 points in mind). If you need to use single quotation marks instead of double quotation marks to include strings, this will be 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 s

mod_deflate module, you can improve the browsing speed of the Web page. 16, the database connection should be turned off when use is finished, do not use long connection. 17. Error messages are costly. 18, in the method to increase the local variable, speed is the fastest. Almost as fast as calling a local variable in a function. 19, incrementing a global variable is twice times slower than incrementing a local variable. 20, incrementing an object property (such as: $this->prop++) is 3 tim
