There are almost no restrictions on the scope of use of const and volatile const or volatile can appear after the parameters of the instance member function, both of which are used to modify the object pointed to by the implicit parameter this of the function. const appears after the parameter list of the instance […]

Hello volatile! Hello, synchronized!
This article has been published simultaneously on my personal homepage Synchronized and Volatile are two keywords used to handle multi-threaded programming in Java. They are used to implement thread synchronization and Ensure visibility. In Java multi-threaded programming, the two are complementary, not antagonistic. volatile In Java, the volatile keyword can ensure the visibility of a […]
[Signal] Signal processing {Timing of signal processing; kernel mode and user mode; principle of signal capture; signal processing function: signal, sigaction; reentrant function; volatile keyword; SIGCHLD signal}
1. Timing of signal processing 1.1 When does the operating system perform signal processing? First of all, we need to make it clear that the data structures for managing signals are all in the process PCB, and the process PCB belongs to the kernel data. Therefore, signal detection and processing must be performed in the […]
Bayesian quantile regression, lasso and adaptive lasso Bayesian quantile regression analysis of immunoglobulin and prostate cancer data…
Original link: http://tecdat.cn/?p=22702 Bayesian regression quantiles have received widespread attention in the recent literature. This paper implements Bayesian coefficient estimation and variable selection in regression quantiles (RQ), Bayesian with lasso and adaptive lasso penalty< strong>(Click “Read the original text” at the end of the article to get the completecode data). Abstract Further modeling capabilities for […]
Java volatile keyword: Do you really understand it?
1. Volatile concept The volatile keyword is a lightweight synchronization mechanism in the Java language. It can guarantee the visibility and ordering of shared variables, but it cannot guarantee atomicity. 2. The role of volatile 1. Visibility In Java, each thread has its own working memory (cache) that stores copies of the variables it uses. […]
Use openlayers to load offline tile maps
1. Demand background Our current project uses openlayer + geoServer’s own vector map. It is a project in cooperation with the public security. Since most governments use sky maps, we need to change geoServer’s vector maps to sky maps and use them with openlayers. Openlayers also You can switch between different map data sources, although […]
Master the volatile keyword in Java
Caching What is cache Cache (Cache) is a temporary storage device used to store computer data. It is used to speed up data access and reduce frequent access to main memory (RAM) or disk. Cache improves system performance by storing the most frequently used data closer to the CPU, providing faster data retrieval. Purpose of […]
How to stop a thread correctly? Why is the stopping method for volatile flag bits wrong?
Java all-round learning + interview guide: https://javaxiaobear.cn Today we mainly learn how to stop a thread correctly? And why is the stopping method of marking bits with volatile wrong? First, let’s review how to start a thread. To start a thread, you need to call the start() method of the Thread class and define the […]

In fact, the cost of trial and error is not high, but the cost of missing out […]
Thread visibility (keyword volatile)
Table of Contents Let me demonstrate this invisibility below: So how to solve this invisibility? Thread visibility means that when multiple threads access shared variables at the same time, modifications to variables by one thread can be immediately seen by other threads. Failure to properly handle thread visibility can lead to data inconsistencies or unexpected […]
