  10 super useful PHP snippets you probably haven’t seen

When working with PHP, it is very useful to have a “toolbox” of handy functions and code snippets that can save lots of time when needed. Today, I’m going to show you 10 super useful code snippets that you probably never heard of. Text messaging with PHP using the TextMagic API If for some reason, you need to send text messages to your clients cell phones, you should definitely have a look to TextMagic. They provide an easy API which allow you to send SMS to cell...

  C vs Java Complete Comparison

Similarities: Java and C have same syntax operators. Difference—thinking Two paradigms: Java: Object oriented language C: Structured language Differences: --Syntax No preprocessor Java does not include a preprocessor and does not define any analogs of the #define, #include, and #ifdef directives. Constant definitions are replaced with static final fields in Java. (See the java.lang.Math.PI field for an example.) Macro definitions are not available in...

  Function Pointers in C are Underrated

The function pointer in C is, in my opinion, one of the most ignored gems of the language. It’s the kind of feature you rarely need, and then suddenly, one day, you find yourself in dire need of it, as evidenced by the real-life use-case below. If you don’t know what a function pointer is in the first place, here’s the meat of it: it gives you the ability to pass a function around like a normal variable. If you know Python / Ruby / Lisp, you might know it by the name...

  JavaScript Needs Blocks

While reading Hacker News posts about JavaScript, I often come across the misconception that Ruby’s blocks are essentially equivalent to JavaScript’s “first class functions”. Because the ability to pass functions around, especially when you can create them anonymously, is extremely powerful, the fact that both JavaScript and Ruby have a mechanism to do so makes it natural to assume equivalence. In fact, when people talk about why Ruby’s blocks are different ...

  Functional Programming in C++

Probably everyone reading this has heard “functional programming” put forth as something that is supposed to bring benefits to software development, or even heard it touted as a silver bullet.  However, a trip to Wikipedia for some more information can be initially off-putting, with early references to lambda calculus and formal systems.  It isn’t immediately clear what that has to do with writing better software. My pragmatic summary:  A large fraction of th...

  Understand unsafe in GoLang

Before going to understand unsafe package in GoLang, the first thing needs to talk about is the pointer in GoLang. If you have a background of C language, you must know what pointer means and its usage. With pointer, you are free to operate any data at memory level which means you have great power, but this means that you have great responsibility as well. That's why it might be considered unsafe in lots of cases. Take a look at a simple example of doubling an integer. package main import "fmt"...

  Web Security: In-Depth Explanation of X-XSS-Protection

What is X-XSS-Protection X-XSS-Protection is an HTTP response header designed to enable or configure built-in cross-site scripting (XSS) filters in certain versions of Internet Explorer, Chrome, and Safari. The purpose of these filters is to detect reflected XSS attacks in the response and prevent the loading of pages, thereby protecting users from such attacks. The X-XSS-Protection response header was initially introduced by Microsoft in Internet Explorer 8 to control the browser's XSS filter. ...

  Mock Solutions for GoLang Unit Test

In Go development, Unit Test is inevitable. And it is essential to use Mock when writing Unit Tests. Mock can help test isolate the business logic it depends on, enabling it to compile, link, and run independently. Mock needs Stub. Stub function replaces the real business logic function, returns the required result, and assists the test. I involved the related test code for Controllers while writing Kubernetes Operator recently, and there would be mocks for GRPC and HT...

  Tips to improve JavaScript efficiency

Writing JavaScript code is tedious and error prone. You not only need to implement the necessary functions, but also need to ensure cross browser compatibility. This often causes the low efficiency of JavaScript developers. Here we recommend 12 tips you can benefit from. 1. Remove array element by index If we want to remove one element in an array, we can use splice. function removeByIndex(arr, index) { arr.splice(index, 1); } test = new Array(); test[0] = ’Apple’; test[1] = &rsq...

  Load and execute JavaScript

When we load and execute JavaScript in a webpage, there are many points we need to care about because of its design and feature. There are two features about JavaScript execution in a browser: 1). The JavaScript codes will be executed immediately once loaded;2). When JavaScript codes are being executed, they will block the following contents (including page rendering and other resources downloading). So if there are multiple js files to be loaded, these codes will be executed sequentially. Since...
