I. Remote Operation 1.1 Distributed Version Control System A distributed version control system, simply put, is a central server repository connected to multiple local server repositories. This allows multiple developers to view their respective code. 1.2 Cloning a remote repository Using HTTPS protocol: There are no requirements when using HTTPS, and you can directly clone … Read more
Foreword: After mastering the basic operations of a Git local repository, “how to correct erroneous commits,” “how to recover accidentally deleted files,” and “the risks and solutions for version rollback” become key topics for developers to advance. In code development, accidental changes to configurations, committing redundant files, and deleting core code are unavoidable. Git’s version rollback, … Read more
I. Creating a Project II. File-based routing mechanism III. Dynamic Routing Parameters Note: When matching URLs, static routes have higher priority than dynamic routes. 1. Basic usage http://localhost:3000/about/1http://localhost:3000/about/1 import {useRouter} from ‘next/router’ // Import the hook function export default function AboutProjectPage() { const router = useRouter() // Use the hook function return ( <> <div> … Read more
1. Overview and Positioning 1.1 Background and Challenges of Microservices Microservices break down business logic into multiple autonomous mini-services that evolve as independent deployment units. While this brings decoupling to teams and improved delivery efficiency, it also introduces runtime governance challenges: service discovery, configuration distribution, interface compatibility, fault tolerance and resilience, observability and capacity planning, … Read more
To Blob add a filename to an object, you can do so by Blob casting the object to File an object. File Objects inherit from Blob objects and provide additional properties, including name the `name` property, which allows you to set a name for the file. This method works in most modern browsers, but note that Internet Explorer does not support File … Read more
Introduction to closures In JavaScript, redeclaring the same variable can lead to variable conflicts. In such cases, closures can be used to create independent execution environments. In JavaScript, a closure refers to a closed execution environment. It means a function can remember and access the scope in which it was created, … Read more
Debouncing Within a given time period, events are frequently triggered, but only the last one is executed. This is achieved using a timer at the underlying level. Use the _.debounce() function grammar: _.debounce(fun, time) Core idea: Implement using the delay function (setTimeout). let time function mouseMove() { if(time) { clearTimeout(time) } time = setTimeout(function(){ n+=1 … Read more
In Java, explicit locks such as `synchronized` and the `Lock` interface can be used to control access to and modification of critical section resources by multiple threads, ensuring thread safety. However, Java also provides lockless programming methods to achieve the same goal while maintaining thread safety. Lockless programming in Java is primarily implemented using `volatile` … Read more
Are you still frustrated by sudden crashes in your Grado app with no apparent cause? Are you unable to reproduce bug reports from users? This article will guide you through the core mechanisms of the Grado logging system, providing three practical tips and two real-world case studies to help you easily pinpoint problems, optimize performance, … Read more
Logging is a crucial aspect of Python application development. It helps us track application runtime status, debug problems, and analyze performance bottlenecks. Python’s standard library provides a module called `logging` that makes implementing logging functionality easy. 1. Import the logging module First, we need to import the logging module: 2. Configure logging Before using logging, … Read more
