  Some hidden XSS injection vulnerabilities

XSS injection refers to a Web page generates some unexpected executable js codes based on user input  and these executable codes are executed by web browser,i.e, the source code sent to web browser by the server contains some illegal js codes, and these illegal js codes are related to user's input. Common XSS injection vulnerabilities can be fixed with some functions such as htmlspecialchars(escaping HTML special characters) and strip_tags() or similar, but there are some hidden XSS injecti...

  Why you should be careful about optimizations

In one of my current javascript projects, I have to deal with 3D voxel coordinates. And, sometimes, I have floating points coordinates which must be converted to integers in order to convert them into proper array index. Javascript is a wonderful language, really. However, implementations are sometimes weird, and the way to do something can sometimes have very huge impacts on the performances. Worse, sometimes the classical way is more expensive than the tricky one. So, some peo...

  Introduction to GoLang generics and advanced usage

Generics in Go allow you to write code that can work with multiple types of data, without having to write separate versions of the code for each type. This can make your code more flexible and easier to maintain, as you only need to write and test the code once, rather than maintaining multiple versions. To use generics in Go, you first need to define a type parameter, which is a placeholder for the type that the code will work with. For example, you might define a type parameter called "T" like...

  JavaScript: Passing by Value or by Reference

In JavaScript, we have functions and we have arguments that we pass into those functions. But how JavaScript handles what you’re passing in is not always clear. When you start getting into object-oriented development, you may find yourself perplexed over why you have access to values sometimes but not other times. When passing in a primitive type variable like a string or a number, the value is passed in by value. This means that any changes to that variable while in the function are com...

  How to check whether a struct implements an interface in GoLang

Unlike other programming languages like Java, when implementing an interface in GoLang, there is no syntax like below to explicit tell the relationship: type I interface { } type A struct implements I { } When looking at the code or running the code in GoLang, it might lead to a case one doesn't know whether a struct implements interface before trying to use it as some interface. According to GoLang spec, as long as a struct implements all functions of an interface, it is considered as having i...

  Magic CSS shape

There is a question on StackOverflow which states that someone finds a CSS sample on http://css-tricks.com/examples/ShapesOfCSS/  , the sample shows a triangle created with pure CSS. The source code is :#triangle-up {width: 0;height: 0;border-left: 50px solid transparent;border-right: 50px solid transparent;border-bottom: 100px solid red;}The question is how these few lines can create a triangle? Next we give the answer and the detail illustration to this question We need to consider the B...

  GitHub Copilot may generate code containing GPL code

GitHub Copilot is a new AI-powered code completion tool that can generate code snippets from natural language descriptions. It is powered by OpenAI Codex, a deep learning system that has been trained on billions of lines of public code. GitHub Copilot claims to be a “copilot, not a pilot”, meaning that it is not intended to write code for you, but rather to help you write code faster and better. However, some developers have raised concerns about the legal and ethical implications of...

  JavaScript-style object literals in PHP

The object literal notation in JavaScript looks like: var fido = {name: "Fido", barks: true}; or var fido = {}; fido.name = "Fido"; fido.barks = true; From assoc arrays to objects In PHP you would call that an associative array. $fido = array( 'name' => "Fido", 'barks' => true ); And you can easily make it an object too: $fido = (object)$fido; echo gettype($fido); // "object" Or if you want to start with a blank object and add stuff to it: $fido = (object)array(); or $fido...

  Understanding Slice Behavior in Go

In Go, understanding how slices behave when passed to functions is crucial for writing efficient and bug-free code. This behavior is often a source of confusion for many developers, especially those new to the language. In this article, we'll explore the difference between passing slices by value and by reference, and how it impacts the modification of slices within functions. Introduction In Go, slices are a fundamental data structure used to work with sequences of elements. They are essentiall...

  Why does it take Task Manager longer to appear when you start it from the Ctrl+Alt+Del dialog?

Amit was curious why it takes longer for Task Manager to appear when you start it from the Ctrl+Alt+Del dialog compared to launching it from the taskbar. Well, you can see the reason right there on the screen: You're launching it the long way around. If you launch Task Manager from the taskbar, Explorer just launches taskmgr.exe via the usual Create­Process mechanism, and Task Manager launches under the same credentials on the same desktop. On the other hand, when you use the secure ...
