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...

In concurrent programming, a Mutex is a commonly used synchronization mechanism to protect critical resources and prevent data races. However, in certain specific scenarios, especially when the lock-holding time is short and the number of threads is limited, a more lightweight lock known as a Spin Lock can provide higher performance.What is a Spin LockA Spin Lock is a form of busy-wait lock. When a thread attempts to acquire a lock held by another thread, it continuously checks the lock's status (i.e., "spins") until the lock is released, at which point it takes ownership. This waiting method ...

In Golang, nil is a predefined identifier that carries different meanings in various contexts, but typically represents "none", "empty" or "zero value". It can be assigned to variables of pointer, slice, map, channel, function, and interface types. Understanding the significance of nil is crucial for writing robust Go programs, as mishandling nil can lead to unexpected issues.nil in PointersIn Go, pointers are a fundamental type that stores the memory address of a variable. When a pointer is declared but not initialized, its value is nil. The following example code illustrates this:package mai...
