  Beauty of code : How to write graceful PHP code

Writing good code is an art. In order to achieve this, it is necessary to develop good programming habits at the beginning. Good programming habits not only contributes to the early project design (modular),but also allows you to the code easier to understand, so that the maintenance of the code is easier. Bad programming habits will result in more code bugs, and will make future maintenance work difficult. We introduce some good programming habits taking PHP as example. Hope this will help you....

  Understand more about Go basics with one interview question

First, let's take a look at below Go interview question: package main const s = "Go101.org" // len(s) == 9 // 1 << 9 == 512 // 512 / 128 == 4 var a byte = 1 << len(s) / 128 var b byte = 1 << len(s[:]) / 128 func main() { println(a, b) } What would be the output in your mind? The output would be 4 0. Surprising? Before getting to the output values, some concepts in Go need to be introduced and explained in more detail. len()  len() is a built-in function in Go to get t...

  The evolving history of asynchronous operation in JavaScript

JavaScript is single threaded, it means there would be only one task running at any point of time. But this would slow down the overall program execution if there is long running task, hence asynchronous task execution is desired in complex cases. To achieve asynchronous task execution, there are a few options introduced in JavaScript. setTimeout/setInterval Event Promise Async/Await setTimeout/setInterval is one of the first mechanisms introduced in JavaScript to simulate asynchronous operati...

  The requirements of DevOps development

DevOps has become a popular and commonly adopted software development model in IT industry in recent years. Its popularity is partially because it advocates it could improve software development efficiency, delivery speed and cost saving. This is especially favored by managers who become the main force to promote this type of development model in their companies. However, we must be cautious about DevOps model as well. With their advantages, they also bring challenges to development teams and th...

  Reflection in Java

What is Reflection? Reflection is a feature in Java that allows a program to obtain information about itself at runtime and dynamically manipulate the properties, methods, and constructors of classes or objects. With reflection, we can instantiate objects, call methods, and set properties without knowing the exact class name beforehand. The core of the reflection mechanism is the Class object, which represents a class. The Java Virtual Machine (JVM) automatically creates this Class object when i...

  Empty slice vs nil slice in GoLang

In Go, there is a type called slice which is built on top of array. It's a very convenient type when we want to handle a group of data. This post will explain a subtle but tricky difference between empty slice and nil slice. A nil slice is a slice has a length and capacity of zero and has no underlying array. The zero value of slice is nil. If a slice is declared like below, it is a nil slice. package main import "fmt" func main() { var a []string fmt.Println(a == nil) } The output will be t...

  A simple example on implementing progress bar in GoLang

Sometimes when handling a long running process, there would be need to track the progress so that people know something is still running instead of doubting something goes wrong. In this case, a progress bar which indicates the current status and progress would be desired. This post will show an example on how to implement progress bar using GoLang. Let's take a look at the final outcome first before jumping into the implementation detail. The key in the implementation is actually just the \r ...
