  Rust vs Go: how to choose the best programming language for your project?

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...

  REST和gRPC对比全知道

长期以来,REST是构建API的唯一“标准”。它取代了混乱的“太多XML”的SOAP。但是近年来,出现了新的替代品。2015 年,Facebook 向公众发布了GraphQL,而 2016 年,Google 推出了gRPC。本文将重点介绍 gRPC,并与仍广泛使用的 REST 进行比较。概述以下表格将为您提供讨论点的概述,并显示 REST 和 gRPC 的优劣之处。主题RESTgRPC标准化没有标准定义明确范式基于资源RPC服务模式仅一元一元、客户端流、服务器流和双向流要求任何HTTP版本、JSON解析器HTTP/2...

  Mastering Async/Await in JavaScript: A Comprehensive Guide with Examples

As a veteran JavaScript developer, I have seen the evolution of JavaScript's asynchronous programming landscape. From callbacks to promises and now async/await, JavaScript has come a long way in making it easier to handle asynchronous operations in a clean and readable manner.In this article, we will delve into the world of async/await and explore why it has become a popular choice for handling asynchronous operations in JavaScript. We will cover the basics of async/await, its syntax, and how it differs from traditional promises. Additionally, we will go through several examples of using async...

  Different ways of handling concurrent job in GoLang

GoLang provides very good support of concurrency and the way to make some code to run concurrent is pretty simple and straightforward. Adding a simple go before a normal function call will make the function call asynchronous.In real cases normally people would concurrently run some jobs to improve the speed and efficiency. One important part of running jobs concurrently is about aggregating results so that the consequent function call would be able to proceed. There are multiple ways handling this scenarios.One of them is using WaitGroup from sync package. The pattern is like:var wg sync.WaitG...

  Hadoop or Spark: Which One is Better?

What is Hadoop?Hadoop is one of the widely used Apache-based frameworks for big data analysis. It allows distributed processing of large data set over the computer clusters. Its scalable feature leverages the power of one to thousands of system for computing and storage purpose. A complete Hadoop framework comprised of various modules such as:Hadoop Yet Another Resource Negotiator (YARNMapReduce (Distributed processing engine)Hadoop Distributed File System (HDFS)Hadoop CommonThese four modules lie in the heart of the core Hadoop framework. There are many more modules available over the interne...

  Can a == true && a == false be true in JavaScript?

JavaScript is a weak typed language and it has a loose comparison feature where two objects/values of different type can be compared using == operator. This provides developers great flexibility and confusion at the same time. Before understanding how == works in JavaScript, can you first answer the question in the post title? Can a == true && a == false be true in JavaScript? Normally, we would think that this expression will always return false since a can be either true or false but cannot be both. However, in JavaScript, the above expression can return true indeed.If we h...

  Why 0.1+0.2 != 0.3

In programming languages such as JavaScript, c/c++, Java and Matlab, you will find that you will get unexpected result when doing float point calculation. For example, when calculating 0.1 + 0.1, you will not get 0.3:> 0.1 + 0.2 == 0.3false> 0.1 + 0.20.30000000000000004Don't be surprised of this result, this is the end result of IEEE 754 standard, float point number cannot be accurately represented according to IEEE 754 because:No enough memory is allocated for representing the numberIt needs a range to ensure the accuracyJavaScript uses 64-bit floating point representation, which is the...
