  Prototypes and Inheritance in JavaScript

Forget everything you know about object-oriented programming. Instead, I want you to think about race cars. Yes – race cars. Recently I was watching the 24 Hours of Le Mans –a popular racing event in France. The fastest cars in the race are the Le Mans Prototypes. Although these cars are built by car manufacturers like Audi and Peugeot, they are not cars you’ll see on the streets and highways of your home town. They are built exclusively for high-speed endurance ra...

  SkipList in Go

Algorithmic thinking is the must-have in the coding world, so I have been keeping the routine of algorithm practice every week, consolidating my knowledge of data structures on one hand, and improving my coding skills as well. A difficult one happened to be stuck in my mind- Implement SkipList with Go, which took me quite a weekend. Below is the front-line report of how I finally got the hang of it. First, from its concept. Wiki has explained it well. a skip list is a probab...

  The Mature Programmer

1. The Mature Programmer The mature programmer manages their own time and productivity well. The MP knows that maintenance is as much work as the initial writing and code always takes longer than you think. The MP knows that any changes to code can introduce bugs, no matter how seemingly trivial. The MP knows that premature optimization is foolish and dangerous. The MP knows that sexy coding like writing big complex systems from scratch is rarely the best way to go. The MP does not get...

  Efficiency of code execution

If you want to optimize your program codes, you need to find their Hotspot, i.e, the codes which are executed most frequently. If you can optimize this portion of codes a bit, you may gain much improvement of your code efficiency. Here I give you three examples about efficiency of code execution.1. PHP's Getter and Setter (From Reddit)This example a quite simple, you can skip it if you want.Consider the code below, we can find it's slower when we use Getter/Setter method to read a member variabl...

  10 reasons why Dart is cooler than JavaScript

Dart is a new programming language from Google and after coding JavaScript for over one year now, I immediately felt in love with it. Coming from the Java world I had a good bunch of things I had to learn before I could use JavaScript. Some people say, you need to dig deep into JavaScript, otherwise you are not allowed to speak about the pros and cons of a language. I am not a JavaScript Ninja. But I strongly believe a programming language should be easy to learn, easy to understand and s...

  Never create Ruby strings longer than 23 characters

Looking at things through a microscopesometimes leads to surprising discoveries Obviously this is an utterly preposterous statement: it’s hard to think of a more ridiculous and esoteric coding requirement. I can just imagine all sorts of amusing conversations with designers and business sponsors: “No… the size of this <input> field should be 23… 24 is just too long!” Or: “We need to explain to users that their subject lines should be les...

  Let's talk about JavaScript deep clone

In JavaScript, deep clone means creating a brand new object that includes all nested objects, with all properties being completely independent copies. This is different from shallow copying, which only copies the first-level properties, with nested objects being referenced rather than copied. There are multiple ways to perform deep copying in JavaScript, but the best one to use depends on the specific use case. Can use JSON.parse & JSON.stringify? ❌ JSON.parse(JSON.stringify(obj)) is a dep...

  Preprocessor magic:Default Arguments in C

This post is for programmers who like C or for one reason or another can't use anything else but C in one of their projects. The advantages of having default arguments is not something that needs convincing. It's just very nice and convenient to have them. C++ offers the ability to define them but C under the C99 standard has no way to allow it. In this post I will detail two ways I know of implementing default arguments in C. If a reader happens to know additional ways please share in ...

  6 Most Effective Methods to Code HTML and CSS

IntroductionJust few weeks ago, I have resigned as a "full on" web developer (frontend, backend, server admin and misc) and moved on to become a pure frontend developer (yay)! It is a really exciting change, as you might know frontend developer role didn't exist few years ago. Thanks to the introduction of HTML5, CSS3 and Javascript framework, frontend development has to be separated from backend due to its complexity, and I think I'm trained to fit in that gap nicely.For many years, I've equipp...

   Move.Me Writing Your Own WebSocket Server

The WebSocket protocol has applications beyond plain vanilla web development.  I will explain how the protocol works, how to implement your own server and share some insights I had along the way. Before we get down and dirty, I will explain what I’ve been doing with it. At this point I expect many of you are saying “I’m not working on a web game this doesn’t seem relevant to me.” Well, neither am I. I embed a WebSocket server into my game engine and wit...
