Javascript setAttribute removeAttribute Methods Tutorial
 
08:16
Script: http://www.developphp.com/video/JavaScript/setAttribute-removeAttribute-Methods-Tutorial Learn to apply the setAttribute and removeAttribute methods of Javascript. Since Javascript has become a necessary running component of the web and HTML5 relies heavily upon it we can lean on it more and more to reduce our HTML markup cosiderably much the same way we ruduce our HTML markup by separating out the CSS styling from it. There are also times when in mid flow while a user is using your application, you may have to set or remove an HTML attribute from a tag at runtime. Which makes this a necessary set of methods for Javascript application authors to know. This tutorial is for people that have a good understanding and working knowledge of HTML attributes, and they wish to enhance their Javascript skills in regards to HTML5 dynamic attribute handling. THis also applies to HTML4 attributes. If you are not aware of all of the HTML and HTML5 attributes, web search a list of them.

Magic methods in PHP5
 
08:02
A brief overview of some Magic Methods in PHP5 Object-Oriented Programing. Welcome to this screencast about magic methods in PHP. You can find the official documentation at http://www.php.net/manual/en/language.oop5.magic.php. Please note that the naming convention of a magic method in PHP is that its name begins with a double underscore and also that a magic method should always be public. That said I am going to create a new class, that I will call magic. I will give it some properties, respectively name, set to John, and age, set to 12. Now I am going to create a variable called underscore that will instantiate the magic class into a new object. And I am going to create a string to test that my object has been instantiated successfully. Let's test in a browser, and it works! John is 12 years old. Now let's see our first magic method, which is the constructor. Let's say that every time I want to call my class magic into an object, I want to choose different name and age that I will set in the instantiation. I am going to create a method called double underscore construct expecting the parameters name and age, and setting those to my object properties. And now I am going to add parenthesis after my instantiation declaration with the parameters I want, here Jack and 30. Let's test in the browser, and it works! Now let's say I want to protect my object properties name and age, using the protected keywords. Now if I go back to my browser, it will throw an error because I am trying to access protected properties, which PHP rightfully sees as an illegal operation. So I am going to use an other magic metod, called double underscore get, that PHP will call every time an object instantiation is using a protected or a not-found property. The double underscore get magic method is expected the key argument. In my function body, I will just allow the protected property to be accessed. Now I go back to my browser and it works. Now let's imagine that in runtime, after my object has been constructed, I want to change the name property, let's say to Peter. PHP will throw an error because I am trying to set a property that is either protected or not found - in this case, protected. To fix that, I am going to use another magic method, called double underscore get, waiting for a key and a value parameter, and in my function body, I will just allow the protected property to be set to value. Now I go back to my browser and the new name has been applied. Now I am going to create a regular method, called walk. Upon calling, it will display a message. I call the walk function in my runtime and, back to my browser, you can see that the message is successfully displayed. Now I am going to call a method that hasn't been set, let's say the method eat. As you can see on the browser, PHP throws an error because you are calling a method that hasn't been set. So we are going to add in our class another magic method, called double underscore call. The same as double underscore get that is called everytime you are trying to access an unknown property, double underscore call is called when you are calling a method that does not exist. double underscore call takes two arguments, the name of the method and an array made of its arguments. Here, in the function body, I am just going to display a message saying that this method does not exist. Back to my browser, and the double underscore call magic method get called successfully. Now we are going to see what happened if I am trying to echo my object. As you can see, PHP throws a fatal error because echo can only print strings and not objects. To be able to print something every time my object is called as a string, I am going to use the double underscore toString magic method. This method is expected to return a string. Let's test it in our browser: it works! Similar to the double underscore toString magic method is the double underscore invoke magic method. This method is going to be called every time you append parenthesis to your object instantiation variable. In the function body I am just going to output the name of the object. The last magic method I am going to show you concerns what happens when your object gets destroyed. As you probably know, when PHP has finished executing a script, it destroys all the variables that have been created during runtime, including objects. This is called garbage collection and its goal is to free memory. And when that happens, if your class has a destructor magic method, it will be called. It will also be called if you destroy the object yourself during runtime, which is what I am doing here using the unset function. Now in my function body, I am just going to echo a message. Let's test it in our browser. We can see that our destructor magic method has been called upon object unsetting. This is all for now but you can find more PHP magic methods at http://www.php.net/manual/en/language.oop5.magic.php

In this programming terms video, we will be looking at the term "Closure". We will learn what a closure is and why they are useful. We will look at examples in both Python and JavaScript. In Python, understanding closures helps us understand common language features like decorators. And in JavaScript, closures will allow us to better understand callback functions and much more.

Let us explore how to use the Custom JavaScript Variable in Google Tag Manager accurately. This Variable is often used to extend the functionality of GTM beyond the provided methods of creating Variables. If you know JavaScript, you can easily input an anonymous function which will be executed when the Variable is checked. This allows for a far bigger range of Variables than before. helpful Links: http://www.simoahava.com/analytics/macro-magic-google-tag-manager/ http://www.codecademy.com/tracks/javascript Variable JS Template: http://pastebin.com/CAfeE48Y Course: http://measureschool.com/youtube more Resources: http://measureschool.com . .

Easy Way to Understand React's Component Lifecycle Methods
 
01:01:44
Welcome to this deep dive on the react component lifecycle workflow. Now if you were relatively new to react then understanding reacts component lifecycle methods may seem a little bit confusing. And so that's what the goal of this guide and then the screencast is going to be, is I want to simply take all of the magic out of the process so that you can understand it. And by the end of it hopefully, you'll see that these methods are even pretty intuitive and you'll see how you can use them in your own projects. Now before we dive into the code and we walk through each one of the lifecycle methods what I want to do is I want to take a step back and I want to draw a real-world analogy for the way that component lifecycle methods made sense to me. And in order to do that we are going to take a drive to a fast food spot. Now you can pick out your favorite, I'm going to go with "In n Out". Anyone watching internationally may not know it. It's a delicious burger joint that I go to whenever I'm in a city that has it. We're going to use this trip to help have a high-level understanding of how these lifecycle methods work. So we're going to go to the drive-thru. But before we do that we first have to drive up to the restaurant as we do that. If you're anything like me you start trying to make up your mind on the kind of things that you're going to want to order. Well in react's world that is called the Mounting process. So what we're doing during the mounting process is we're picking out what kinds of data and processes need to occur when that component is going to load. So if it is some kind of page content type of component and we're getting data from some outside API then we need to implement all the processes that will occur so that when someone navigates to that component then we're putting the right steps in place so that the page will have content. That's the mounting process and it's that first stage kind of like when we're going to the drive-thru and we're starting to pick out what we want to order. So moving right along, we've pulled up to the drive-thru order window and we've placed our order, and that's all part of the mounting process. When we take in relation to react, so that's kind of like us going to a page and having the page load. Now, what happens if the voice coming at the other end says something like "Oh, that is not available today. You need to order something else." Well, we can change our minds and then we can give another order or we could update our order. Well, that is also a lifecycle method in react. So each time that you have a component that gets updated. So that could be as simple as someone typing into a form component or it could be something even more advanced like a WebSocket where you're getting live stream data into your application every time that happens a number of other lifecycle methods occur. So you have access at each stage of that lifecycle. So from the very beginning before the page and that component have even loaded all the way through to when you might need to make some live changes and it also comes into play with how react is so good at performance because during that update process even though you have access to all of the various workflows that are occurring when something has been updated react is very good at being able to tell the difference so in other words if you have a big page component and only one part needs to update. So if you have eight components on a page and only one of those needs to update in that lifecycle method only one component will need to be updated, so all the other ones remain the same. That's part of the reason why react if implemented properly has very solid performance. So we're almost done with the entire lifecycle. We have gone from the very beginning before we pulled up we decided what we wanted to order. We updated our order when we found out that they had some changes on the menu and then we drive up and we pay, and then we receive our food, and then we drive away. Well, that is called The Unmounting process so as you drive away there are a number of things that you do.

Like the program itself, a function is composed of a sequence of statements called the function body. Values can be passed to a function, and the function will return a value. In JavaScript, functions are first-class objects, because they can have properties and methods just like any other object. What distinguishes them from other objects is that functions can be called. In brief, they are Function objects. For more examples and explanations, see also the JavaScript guide about functions. Description Every function in JavaScript is a Function object. See Function for information on properties and methods of Function objects. Functions are not the same as procedures. A function always returns a value, whereas a procedure might not. To return a value other than the default, a function must have a return statement that specifies the value to return. A function without a return statement will return a default value. In the case of a constructor called with the new keyword, the default value is the value of its this parameter. For all other functions, the default return value is undefined. The parameters of a function call are the function's arguments. Arguments are passed to functions by value. If the function changes the value of an argument, this change is not reflected globally or in the calling function.

Object-Oriented Programming with PHP : What is a magic method, and do I need one

Object Oriented Programming, or OOP, refers to the method of programming that invokes the use of classes to organize the data and structure of an application. In this article we are going explore exactly what OOP is in relation to PHP, and look at a few things you should remember about it as well. We'll end of with a simple example of how to use it.

Anjana Vakil - Using and abusing Python’s double-underscore methods and attributes
 
31:01
Anjana Vakil - Using and abusing Python’s double-underscore methods and attributes [EuroPython 2016] [21 July 2016] [Bilbao, Euskadi, Spain] (https://ep2016.europython.eu//conference/talks/using-and-abusing-pythons-double-underscore-methods-and-attributes) Python’s double-underscore ('`__`') methods and attributes go by many names, including “special”, “dunder”, and “magic”. You already use some, like `__init__`, but there are many more! In this talk, we’ll see how dunders can be useful, silly, dangerous, and fun! We’ll trick Python’s arithmetic and comparison operators. We’ll make objects behave like dictionaries and containers. We’ll reduce an object’s memory usage, and speed up membership tests. We’ll even try some naughty function hacks! ----- The curious Python methods and attributes surrounded by double underscores ('`__`') go by many names, including “special”, “dunder”, and “magic”. You probably use some of them, like `__init__`, every day. But that’s just the tip of the iceberg! In this talk, we’ll explore the weird and wonderful world of the double-underscore, and find out how dunders can be useful, silly, dangerous, and just fun! We’ll play pranks on Python’s builtin operators for arithmetic and comparison. We’ll make arbitrary objects behave like dictionaries and containers. We’ll reduce an object’s memory usage, and speed up tests for membership. We’ll even try some naughty function hacks that we should never use in real life! You'll get the most out of this talk if you're already comfortable writing object-oriented Python code. If you already use special dunder magic in your own code, that's excellent! You’ll have a chance to share your tips & tricks with the rest of the audience at the end of the talk. _Talk repo_: [https://github.com/vakila/dunders][1] [1]: https://github.com/vakila/dunders

Node.js Tutorial For Beginners Part 9 - Callback Functions Basics
 
05:04
This Node.js tutorial is a simple introduction to callback functions. These Node.js tutorial series will make you into a better developer whether you are a beginner or a seasoned programmer. Even though this is a Node.js tutorial for beginners you can still relearn the basics and get a more structured understanding of Node.js framework. If you are a beginner Node.js developer than this is a wonderful opportunity to start learning Node.js from the ground up. In these Node.js tutorials you will first learn the theory and technical definitions behind the concept and then actually see an example of how it is used. The unique part of these Node.js tutorials is that each of them not only explains you the concepts but also explains you their purpose and why they exist in the first place. This in turn will give you a much broader understanding when you are working on your own projects or even products! One of the other things to expect from these Node.js tutorial series is that they will connect these simple concepts to the real life – meaning in each video you will learn about the best practices, dos and donts. Instead of just learning the theory you will also learn the practical application. I hope that this Node.js tutorial teaches you about callback function. Thank you for watching and being part of my journey! Thank you for watching and learning about callback functions, wish you all the best. Never stop improving! #NodeJS #Programmer #Coder #WebDeveloper #WebDevelopment #Coding #ComputerProgramming #AvetisG #ProgrammingTutorial #WebDev #Node #NodeDeveloper #Developer #NodeProgrammer #NodeJSProgrammer

Mariko Kosaka - Making a Robot Eye with JS or Magic of Computer Vision Unraveled - CascadiaFest 2016
 
33:38
Have you ever wondered how computers see images? Do you want to work on an AR (Augmented Reality) project or build a NodeBot that can recognize and track your face? How about making your own Instagram-like app or finding similer images in Pinterest collection? When you work with an image as your data input, sooner or later you'll encounter the magic term Computer Vision. It can be intimidating to get started. At first, that led me to choose a common and powerful library that works like magic in an unfamiliar language (C++). It felt like the library was a black box and I had no control. I started to wonder, what is so magical about computer vision? After all it is just code someone wrote. Can we unravel it? and reconstruct in JavaScript?? The answer is YES. In this talk, we'll start by getting image data from canvas object, then transform the data to alter an appearance of the image. You will get insight into what data looks like to a browser (hint: it's just an array of numbers !). Next we’ll talk about how to interpret and analyze the data in a meaningful way. Finally, we'll apply what we learned and go through simple image analysis process to build your own AR app in vanilla JavaScript!
