Basic ConceptsWhat are the characteristics of the deferred statement defer in Go language? When is it usually used?The deferred statement(defer statement) in Go language has the following characteristics:Deferred Execution: Deferred statements are executed before the function containing them exits, regardless of whether the function returns normally or encounters an exception.Last In, First Out (LIFO): If there are multiple deferred statements, they are executed in the order of last in, first out (LIFO). In other words, the last deferred statement is executed first, and the first deferred stat...

Rust and Go, these two modern programming languages, with their unique advantages, are becoming hot topics in the developer community. Their competition in performance, security, simplicity, feature set, and concurrency not only influences developers' choices but also foretells future trends in software development.Battle of Performance: Rust's Precision vs. Go's EfficiencyRust, developed by Mozilla Research, has become the preferred choice for performance-sensitive applications due to its zero-cost abstractions and memory safety features. It ensures memory safety through concepts like ownersh...

When crafting a tweet, there are instances where we may wish to include a link, but we prefer the preview to be shown without displaying the URL explicitly after the tweet is published. How can we accomplish this? This article outlines the steps to achieve it.To begin, copy and paste the link you want to share into the tweet box.After clicking Post, the tweet will be published without displaying the link; instead, it will showcase the page preview, and clicking on the preview image will open the page.What if you want to add your own description about the linked page while still concealing the ...

Casual TalkGolang is quite enjoyable to write, aside from the tedious if err != nil checks. One of the fundamental reasons for the joy is goroutine, a core feature of Golang. Understanding goroutines in detail is worthwhile, as they contribute significantly to the pleasure of working with Golang. So, let's talk about goroutines, hoping to provide some insights to the readers.TL;DR: We'll start by talking about assembling a computer, then delve into some concepts of the operating system, such as processes and threads, before exploring goroutines themselves.Assembling a ComputerLet's focus on de...

IntroductionIf you're only using gRPC at the application layer, I believe studying the examples on the gRPC official website is sufficient. However, when planning to extensively use gRPC within a team, you will face many challenges, such as authentication schemes between services, routing solutions for multi-region services, and compatibility solutions with existing RESTful services.I recently realized that applying a technology stack requires mastering a wealth of information about that stack to ensure its stability in production use. This article starts with the most basic packet capturing a...
