Golang已经开源了13年，在最近的TIOBE编程语言排名中，于2023年3月再次进入前十名，并比2022年底的排名上升了两个位置。Go在2022年底提高了2个排名许多第一次接触Go的开发者来自面向对象的编程语言，比如Java、Ruby等，他们在学习Go后第一个问题通常是：Go是一种面向对象的语言吗？在本文中，我们将探讨这个问题。追溯在广为人知的Go编程语言“圣经”《The Go Programming Language》中，有一个Go与其主要祖先编程语言之间的亲缘关系图表。Go与其主要祖...

Artificial General Intelligence(AGI) has long been a topic of fascination and concern for technology leaders, with some seeing it as humanity's ultimate tool, while others view it as an existential threat. This clash of perspectives was on full display during the acquisition of DeepMind by Google in 2014, as two tech titans, Elon Musk and Larry Page, found themselves on opposite sides of the debate. While Page saw AGI as a necessary and desirable step in humanity's evolution, Musk was more wary of its potential to destroy humanity. Their differing perspectives set the stage for a fascinating c...

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�...

Featuring encryption, anonymization, hashing, and access controlNetwork security incidents occur now and then, mostly caused by data leakage. Data security has aroused widespread concern, and the community keeps working hard on approaches to simplify data security, especially in sensitive data protection.Sensitive data includes but is not limited to personally identifiable information (PII) like names, ID numbers, passport numbers, driver’s license numbers, contact information like addresses, phone numbers, account credentials like usernames, passwords, PINs, and financial information li...

BackgroundBefore getting into the main content, let me give a brief introduction to WaitGroup and its related background knowledge. Here, the focus is on the basic usage of WaitGroup and the fundamental knowledge of system semaphores. For those who are familiar with these, you can skip this section directly.WaitGroupWaitGroup is one of the most common concurrency control techniques in Golang, and its function can be roughly compared to the join() in concurrency control of other languages' multithreading. The sample code is as follows:package mainimport ( "fmt" "sync" "time")func main(...

IntroductionIn the world of concurrent programming, Go channels have quickly become a popular tool for building fast and efficient applications. Utilizing channels can help you take full advantage of the power of Go's lightweight threads, or goroutines, and enable you to easily and effectively manage data sharing and synchronization. In this article, we'll dive deep into the world of Go channels and show you how to build concurrent applications like a pro.Understanding Go ChannelsTo start, let's take a closer look at what Go channels are and how they work. In Go, channels are a way to communic...

BackgroundThe Go 1.20 version was officially released in February 2023, it introduced the PGO(Profile Guided Optimization) mechanism.The basic principle of PGO can be divided into the following two steps:First, profiling is performed on the program to collect data about the program's runtime and generate a profiling file.When compiling the program, enable the PGO option, and the compiler will optimize the program's performance based on the content in the .pgo file.When compiling a program, the compiler will perform many optimizations, including well-known optimizations such as inline optimizat...
