Docker tutorial for beginners - part 1: Free Digital Ocean Credit! Docker is amazing, and it doesn't have to be difficult to understand. In these tutorials, I'll be breaking down exactly what a Docker container is and how to use it. I've found a lot of Docker container tutorials on the web, but I still hear from developers that it's hard to grasp exactly what Docker is and how to work with Docker images & containers. In this video, I'll compare Docker to Vagrant and explain the differences, then in the next video, we'll do our first miniature deployment with Docker by creating a Digital Ocean machine with Docker installed and then running a Docker web server container on the machine. Later on, we'll get into docker machine, docker compose (fig) and a whole mess of other fun tooling. Next up: how to run your first Docker web server - High-Availability Docker 1: - Cluster computing - CoreOS is our solution here. CoreOS allows us to make an expandable cluster of computers so we can add more computers should our application need more power to scale. CoreOS also allows us to run services on any machine in the cluster and they can all communicate with each other. High-Availability Docker 2: - Scheduling: we shouldn't manually choose which app runs on which machine - this idea doesn't work at scale. Fleet will be our scheduler that decides where our apps/services run. If a CoreOS machine goes down, fleet will reschedule any services that it was running onto a new machine. High-Availability Docker 3: - Service Registration Since we never know what ip address or port a service will be running on, we need to register that service so other services can find it and communicate with it. We'll use Etcd and Flannel for this High-Availability Docker 4: - Service Discovery: Now that services have registered, we can discover them and load balance between them with a generic docker nginx container High-Availability Docker 5: - Public DNS: Once the app is working, we need a fixed way for the outside world to access it. We'll use Nginx and Confd for this. Confd will watch Etcd for service registration and when services come/go, it will build a new configuration file for Nginx and reload Nginx.


A big question in React JS is State vs Props. State is essentially any data that relates to the internals of a React component, but has nothing to do with the outside world. Props are data that the React.js component depends on to function and render correctly. GET THE SOURCE CODE: React JS 1: Intro & Workspace Setup (Coming Tues, Feb 2@11CST) React JS 2: Anatomy of a Component (Coming Wed, Feb 3@11CST) React JS 3: Composing Multiple Components (Coming Thurs, Feb 4@11CST) React JS 4: State, Props & Data (Coming Fri, Feb 5@11CST) React JS 5: Events & Data Changes (Coming Mon, Feb 8@11CST) React JS 6: React Router & Intro to Single Page Apps (Coming Tues, Feb 9@11CST) React JS 7: React Router Params & Queries


Not using a build system/task runner? You're missing out. A build tool like Grunt, Gulp, Brunch, etc will drastically improve your local development workflow as well as your deployed website. After watching this, checkout the next video on building your first system with Grunt: In this video, I'm going to cover: - What a build system does for you - Why you need one - What a task runner can do for your local development workflow - How to improve performance for your website in production The bottom line is, a good build system will take your web development to a whole new level. It can feel like a lot of setup, but you only code it once.then use it for the life of your project. It's well worth the effort!


This jQuery Tutorial for beginners will help you get jQuery on your page and get up-to-speed with how to use basic jQuery commands. What is jQuery? As you'll see in this tutorial, even beginners to javascript can write jQuery within minutes. It's also the most universally used javascript library in the world at present, so odds are your next employer will be using it. The first thing we'll be doing in this jQuery lesson is showing, hiding, fading, & sliding. Next, we'll modify contents of elements and learn to do a better job keeping our code clean. Lesson 2: Listen to user events and respond with jQuery actions! Lesson 3: Clean up the jQuery by putting some data in the HTML


Scope and Context are in every language, but because Javascript is always firing callbacks and running asynchronous tasks, it's easy to lose sight of what scope & context you're in. Scope and context are not the same thing. Scope is variable access - what variables the current piece of code has access to, context is the value of `this` - when you type `this` in your code, what object is it referring to? This javascript tutorial covers scope and how it plays out in all of the functions that you create.

The core of React js programming is React components. Just like everything in HTML is an element, everything in React is a component. In this video, we'll break down how a component works. GET THE SOURCE CODE: React JS 1: Intro & Workspace Setup (Coming Tues, Feb 2@11CST) React JS 2: Anatomy of a Component (Coming Wed, Feb 3@11CST) React JS 3: Composing Multiple Components (Coming Thurs, Feb 4@11CST) React JS 4: State, Props & Data (Coming Fri, Feb 5@11CST) React JS 5: Events & Data Changes (Coming Mon, Feb 8@11CST) React JS 6: React Router & Intro to Single Page Apps (Coming Tues, Feb 9@11CST) React JS 7: React Router Params & Queries WATCH THESE FIRST: ES6: WEBPACK: If you're new to Javascript, the MODULAR JAVASCRIPT course is also helpful:


Javascript is so weird.and so AWESOME. There are 5 root things that make it this way. If you're new, learning to grasp these 5 concepts will get you a LONG WAY in your JS programming. Honestly, there are a LOT of intermediate programmers who don't understand these concepts. Many coders who know how to work around them don't really understand how and why it works, they just know do-this-and-it-works. Here's video 1, First-Class Functions Watch the full playlist: _


MobX is AWESOME. It makes React.js programming fun and it.just.works. GET THE CODE: THERE ARE 2 BRANCHES: master for where we end up and start for where we start. MobX builds on the concept of observable values. When React observes a value, it can automatically update the UI whenever the value changes. This makes programming with MobX and Reactjs extremely simple. All it takes to begin is to install mobx and mobx-react and make sure that you are transforming class properties and decorators in Babel. Now, you simply add @observable to your MobX class and you've successfully built a MobX observable store. To observe the store, you pass in a MobX store as a prop and you decorate your React component with the @observer decorator. Voila.you're reacting to store changes in React.


Redux middleware is awesome, it allows you to keep the simplicity of Redux, yet extend it's functionality. Adding global things like loggers, error handlers, etc are incredibly simple. In this react redux tutorial, we're going to create a redux logger middleware and error handling middleware that intercept every redux action in our react.js app. As you see, adding redux middleware to our react app is incredibly easy.


Yarn is the hot new drop-in NPM replacement utility for projects using node.js packages. It's way faster, more stable, and more secure than NPM and you can use it with zero configuration on your end. In the sample for this video, the NPM install takes between 20 and 30 seconds for just a few packages, while the yarn install takes 4-10 seconds to install all of the node packages. Yarn is also more predictable across environments, so you don't need to npm-shrinkswrap anything, because Yarn manages the dependency tree with a yarn.lock file automatically.


In under 10 minutes, we'll have a production and staging server running on AWS Lambda using Serverless. This AWS Lambda tutorial shows how powerful functions as a service are and how easy it is to get up and running with them. The Serverless framework helps you get up and running in production in 3 commands. (2 if you already have the AWS CLI installed!)


Once your store is in place, you'll want to set up multiple Redux reducers to act on parts of your data store. Redux reducers are great in that they are only aware of part of your data, and the rest of the data is neither reachable nor able to be mutated by your reducer. GET THE CODE! Reducers are a great concept in Redux, because they allow your react application to have specific pieces of data that all update synchronously. All reducers run against your Redux store, and then the store triggers a change event and your entire React.js application re-renders. The biggest thing to keep in mind with Redux reducers is you don't want to mutate your state. ALWAYS return a new state rather than mutating the old state values.


Free RESTful API to use for practice!: In this jQuery AJAX Tutorial for beginners, we're going to be covering an introduction to using jQuery to access a JSON API (Application Programming Interface) to get data and populate it into the document. jQuery AJAX is powerful and is the first step to making dynamic websites that respond to the user actions as they happen. The first part of using jQuery AJAX to access a JSON API is to make a GET request, so this jQuery lesson covers how to make AJAX Get Requests with jQuery & JSON. Lesson 1: jQuery Tutorial for Beginners Lesson 2: Listen to user events and respond with jQuery actions! Lesson 3: Clean up the jQuery by putting some data in the HTML Lesson 4: DOM Traversal with jQuery Lesson 5: Building a jQuery Tab Panel Widget Lesson 6: Building a jQuery Slider / DOM Caching Lesson 8: Ajax Pt 2 - posting data to the backend


Javascript Generators are AWESOME. At first glance, they seem overly simple and not very useful, but with a little bit of library love, they turn your async javascript from awful to joyful. View the code here: If you don't know promises, watch this video: Basically, ES6 generators give you the ability to write async code as if it were synchronous code. It literally looks like you're not even writing async code! Harmony generators are definitely, without a doubt, the most powerful upgrade that javascript is receiving with ES6 harmony.


Nginx ROCKS! In this Nginx Tutorial, we're going to setup Nginx to receive http requests to our domain name (port 80), then proxy to our Express.js Node.js App, which is running on port 3000. View Nginx Configuration Code here: We're also going to set it up Nginx load balancing, so the http requests will get evenly distributed between all of our servers. See full documentation on Load Balancing (upstream) here: Lastly, we're going to setup static file caching on Nginx, so our css, js and image files are only served from our Node.js application the first time.this DRASTICALLY improves application performance.


Get the code here! Many Node.js developers don't know that Node by default only uses one core of your processor. It's intentional and it's a great move. It just means that you have to run cluster to get the full capacity out of your server. When cluster.js runs, it spins up one copy (fork) of your application for each core on your machine, and balances the traffic between them. It also listens to each fork, so if one dies, it spins up a new one in it's place. Clustering is a great way to add stability to your application and drastically increase it's load capacity.


Github Pull Requests are an integral part of Team Workflow. This video covers how to make a new Github feature branch, merge that branch, handle merge conflicts, submit a pull request, discuss the github pull request, and ultimately merge that pull into the master branch of your github repository. - Begin by doing a git pull to get the latest content on your master branch - Run git branch your-feature-name to make a git branch - Code in your changes, add and commit the files - Pull the master branch again and merge it with your new branch - Push the branch up to github and submit it as a pull request - That pull request can now receive comments and code discussion, as well as accept new commits before being merged in with the master branch Other Videos: Github Lesson 1: Bootstrap: AngularJS Tutorial: Javascript Tutorial:


This Javascript Tutorial is a Free Javascript Web Development Course designed for beginners. If you're wanting to know how to Javascript, in this course, you'll get JS tutorials that cover the basics and programming basics from the very beginning. We'll cover Javascript variables, if else statements, functions, arrays, event bindings, and more. If you're learning web development and are ready to learn Javascript for beginners, this is the free tutorial for you.


Immutable Javascript means that we're never going to change a value once it's been set on an object. It might sound complicated, but it's really quite simple. We simply always create new objects and copy their values over. If you want to learn Redux for React.js applications, you have to know how to code immutable JS objects, since it's built upon that. Instead of changing values on a store, we write reducers to modify those values and return a new object instead.


Get your site online as cheap and quick as possible! Tons of people have asked me how do I get my site online ? And here's how. I recommend HostGator (), since they have the best customer service as well as the best price. For $6/mo, you get unlimited domains/websites, so if you're building websites for other people, you can bill them monthly and not have any expenses increase. All you need is a Domain Name: $12/yr Webhost: $5-10/mo I recommend HostGator () Free FTP Program: I recommend Cyberduck () We're going to get a webhost & domain, open an FTP connection to it, upload our files to our webhost, and then we're done!


Let's build a bare-bones Redux app to help you understand how simple it can be. Redux is incredibly simple once you understand where everything goes and what's happening under the hood. GET THE CODE! In this React Redux tutorial, I'll give you a Redux Introduction that shows the bare-minimum requirements to get a Redux app started. You'll notice that there isn't even a React application that I'm using. That's because Redux is not based on React, although it plays beautifully with a React ecosystem. Redux is an elegantly simple way to manage state for your applications. React, Angular.almost any app can plug into a Redux store.


How does the internet work? Most people really don't have to know, but web developers have to know more and more as they grow in their career. These 2 videos cover how the internet works from a web development perspective. Also, check out part 2: How the internet works from a web developers perspective - pt 2 - backend: At a high level, the internet is browsers making requests to servers and getting responses back. Each request contains headers that tell the server how to respond. The server responds with a response and a content-type, which tells the browser what to do with the response. If the content-type is text/html, then the browser knows to treat the response like an html file. If the content-type is image/jpeg, then the browser knows it's a jpeg file. This video covers how the browser parses the html document, and ways that you can improve the loading of your webpage with things like concatenating and minifying assets like javascript, css, etc.


What is a closure? In this Javascript Tutorial, we're going to be learning about closures - our 3rd most misunderstood concept of Javascript. Watch the full playlist: _ Hopefully, we're going to break it down enough to make it simple to understand for newbies and intermediate coders alike. Javascript closures are really not that complex of an idea. The textbook definition of a closure is a function that retains state and scope after it executes. Basically put, when the function's done, a callback might need to access the variables inside later.so Javascript remembers those variables. That remembering of the variables is called a closure.


Let's build a Flux app with React. Flux is a pattern that Facebook created for building consistent, stable web apps with React. React really doesn't give us a way to manage data, it simple accepts data through props or state. So, when it comes to data, there are many ways you can do it. Flux is a great, proven pattern for building apps with React.

Vagrant and VM's can RADICALLY shape your development workflow. Instead of every developer working on their own local server with their own configuration, you can configure a portable local environment that exactly mirrors your staging and production environments. Now developers can spin up this environment on their machine and work completely locally without having to change their machine configuration to accommodate the project they're working on. Also, each project they work on can have it's own VM running it's own configuration that they can spin up. Also, Vagrant provides an easy-to-destroy environment to practice your Linux server administration skills! Here's the Gist on how to follow along:


This Redux tutorial series will show you the schematics of a Redux application. Redux is AWESOME, but it takes a bit to get it setup. There really aren't a lot of moving parts, but there are a lot of ways that you can configure it - namely - configure the store. Redux is like Flux in several ways, but it's different as well. It has these pieces: - Provider: wraps your application, injecting the store - Store: one large store that contains the state for your entire application - Reducers: reducers listen to actions and make changes on the store values. They also cannot mutate the data on the store in any way, but must return a new set of data. - Actions: pretty much just like flux actions, the only difference is that async can be handled in multiple different ways depending on store middleware - Components: React components can be injected with various pieces of store data. React components also trigger Redux actions. This is what makes it all come together.


Parcel is AWESOME. And in many, MANY cases, you don't need to haggle with Webpack anymore, which to some developers is a dream come true, because messing with a build system is one of the most painful parts of modern web application development. Example Code: Webpack Tutorial: Why do you need a build system?


This Javascript tutorial covers functions in Javascript. Functions are a great way to store your code in reusable pieces of Javascript code that can be run at any time. This is a Free Javascript Course designed for beginners. These Javascript lessons cover the basics of Javascript and programming basics from the very beginning. In the first 2 lessons, we covered variables, several Javascript types, if else statements & comparison operators. Now, we'll cover functions. How I did livereload: You can also use the editor - they have a great feature called live preview


Webpack has quickly become one of the most popular choices among web developer build tools. It can quickly build, minify, split & do a whole wonder of other things to your code. Sample Webpack Config: Node.js Introduction: In this webpack tutorial, I'm going to cover a very basic configuration for webpack that will get you started in a project. It will build all of your Javascript and minify and dedupe the code for production. To code react, we just have a little more configuration to add to our webpack config. That will have a full HTML, CSS, JS react application going. Another great build tool is Browserify, which at the beginning of the process works a LOT like Webpack, but in the end, Webpack is a lot more featureful.


This changes EVERYTHING! The fact that Javascript is event-driven is the reason for closures, weird scoping/context, and the myriad of callbacks you see everywhere. Programmers who are new to Javascript - especially Node.js - are often thrown for a loop by the event-driven nature of JS. The bottom line is: Javascript isn't built for making a page, it's built for a user-interface. It listens for user interaction and responds accordingly. And when that response happens, it doesn't run any unnecessary code.just the code to respond to the user. Watch the full playlist: _


What exactly is node.js? Is it a command-line tool, a language, the same thing as Ruby on Rails, a cure for cancer? If you're new to web development, it can be a bit confusing as to what exactly node.js is and to what you should do with it, and there's a lot of information out there.most of which seems to be tailored towards genius-level developers. So, here's a node.js introduction for those who have no idea what it is. We're going to cover the difference between javascript in a browser vs javascript in node.js and the common uses for node.js. To wrap it up, we're going to spin up a quick web server in node.js just to show you how easy it is. Now, learn how to build an Express.js App!


This second part of the jQuery Tutorial for beginners will show you how to do event binding with jQuery. Events happen whenever a user clicks, hovers, drags, types, or does pretty much anything to interact with an HTML element. jQuery allows the web developer to easily write a program to listen to these javavscript events and modify the webpage in realtime. This is often called a dynamic website. You can do all of this in plain javascript, but jQuery makes it incredibly easier. Previous Lesson - 1: Next Lesson - 3:


Once you're done with this, checkout lesson 2 - introduction to CSS: How to put your website online (with coupon): How to build webpages with html, css, javascript tutorial for beginners. In this video, we'll cover how to develop websites using just the computer you have already. I'm using Sublime Text editor and Google Chrome Other great text editors: Atom.io Brackets.io Notepad++ Now, if you just want a website and don't want to be a web developer, don't mess with learning all of this, get a site from squarespace.com and use squarespace plugins from to make your site unique. Learn how to develop your own websites using the computer you already have. The basics of web development is the html file, which is centered around html tags. In this first lesson, we'll cover the basic html tags and how to use them to build a web page. Once you learn HTML, you can use CSS to add style to your pages and JavasScript to add animation and fun features. Learn Javascript with the Javascript tutorials for beginners:

If you're not using a task runner/build system like Grunt or Gulp, you probably need to! Build systems make your websites load faster, code faster, deploy better.it's like a cocktail bomb for coder happiness. Before watching this video: - what is a build system? - what is node.js? So what is Grunt? It's a task runner. It runs tasks - things you have to do every day, or don't do every day because it would take too much effort. With Grunt, instead of spending your time DOING the tasks, you spend your time AUTOMATING the tasks once, then run them in no time for the rest of the project.


While many JS devs still use classical OOP, many have switched to the prototypal pattern for Module Inheritance and Instantiation. Here's the prototypal pattern for JS and why some devs find it simpler to use. View Classical Inheritance here: View the whole modular JS playlist here: SOURCE CODE HERE: Basically, when coding JS OOP with the prototypal pattern, everything is an object. You start with an object literal and, then, to inherit from it, you use Object.create(someModule) to create a child that inherits from it. var parent = some: method ; var child = Object.create(parent); //now add new methods to the child child.newMethod = someMethod; So there's really no difference between inheritance and instantiation in the prototypal method. To create multiple children, simply: var child1 = Object.create(parent); var child2 = Object.create(parent); And there you have it! Also see the source javascript code on how to include a create method so creating is a little more seamless.


Stop downloading javascript and css files yourself! Bower is an extremely useful package manager for web development that not only does the downloading for you, it allows for quick and easy install of all dependencies at once and gives you a method for sharing those dependencies with others. Bower allows you to instantly add jQuery, backbone, or any other framework to your project. You can then save what you added to a bower package allowing everyone else working on your project to install all those dependencies with one command. Bower also allows you to add Github url's for in-house dependencies.


This Javascript tutorial covers Javascript arrays and looping arrays in Javascript. Arrays store lists of items of any type. You can iterate a Javascript array with loops, making it easy to run actions on all of the items in the array. This is a Free Javascript Course designed for beginners. These Javascript lessons cover the basics of Javascript and programming basics from the very beginning.


After a year of coding ES6 full-time, my favorite uses, the best parts, and what you need to know about them. Javascript ES6 comes with a TON of extremely useful new features - all of which you can use TODAY on bot browser and server side code using transpilers like babel or traceur. I highly recommend babel es6 transpilation as it just works well, and I can still easily read the transpiled code.

View whole series here: _ Call, Apply & Bind are avoided by many JS developers, but it doesn't have to be that way. Context is a simple concept that creates complicated realities for developers. In this javascript tutorial, we're going to cover context in javascript, how it's determined, and how/why it changes. When you understand context, you'll feel much more at home with Javascript as a language, and callbacks, especially will feel much more familiar to you.

In this free Javascript tutorial, we'll cover if, else statements & comparison operators. This is a Free JS Course designed for beginners. These Javascript lessons cover the basics of Javascript and programming basics from the very beginning. In the last lesson, we covered variables and several Javascript types. Before covering more types, we'll cover comparison operators and if, else statements. Comparison Operators Covered in this Video: (youtube doesn't allow me to do less-than and greater-than signs, which is really quite silly, so I have to use LT and GT) LT Less than GT Greater than LT= Less than or equal to GT= Greater than or equal to == equal to != not equal to There are also strict equality types === same value and same type !== not same value and same type For example: 2 == 2 will be true - even though they're different types, they're considered equal 2 === 2 will be false because the second value is a number type, where the first is a string type You should use the triple === whenever possible, as it's more specific.


Let's build a high-availability production docker cluster! So web development with Docker pretty much ROCKS - it enables you to build and scale world-class apps that used to only be doable for those working at companies like Google and Netflix. The (not-really-bad) bad news is you have to start thinking like a world-class developer to make full use of it. To go from basic docker container deployment to a full-scale docker system, you'll need to implement a few things: The Diagram: The Code: THIS VIDEO: - Cluster computing - CoreOS is our solution here. CoreOS allows us to make an expandable cluster of computers so we can add more computers should our application need more power to scale. CoreOS also allows us to run services on any machine in the cluster and they can all communicate with each other. NEXT VIDEO: - Scheduling: we shouldn't manually choose which app runs on which machine - this idea doesn't work at scale. Fleet will be our scheduler that decides where our apps/services run. If a CoreOS machine goes down, fleet will reschedule any services that it was running onto a new machine. VIDEO 3: - Service Registration/Service Discovery: Since we never know what ip address or port a service will be running on, we need to register that service so other services can find it and communicate with it. We'll use Etcd and Flannel for this - Public DNS: Once the app is working, we need a fixed way for the outside world to access it. We'll use Nginx and Confd for this. Confd will watch Etcd for service registration and when services come/go, it will build a new configuration file for Nginx and reload Nginx. This docker tutorial will help you understand how to go through every step of this process.


The 4 levels of clean JS ASync programming: Javascript programming can get really ugly, really fast.but not if you know how to avoid callback hell. Code available here: Also watch this video - ES6 Generators Level one: Programming with callbacks - you make it work, but it's ugly Level two: Programming with abstracted callbacks - cleaner for sure, but still messy and way too much repeated code Level three: Promises - much cleaner much more stable code, but still not as enjoyable as code should be Level four: Generators - life is good. This is a javascript promises tutorial / javascript generators tutorial. We're going to show the four levels and why each level is better than the one before it. Along the way, you should learn a decent bit about promises, and even some about generators.

Let's wrap up beginner React.js lessons with handling JS events and data changes in React.js. If you build a Reactjs app correctly, each component is able to be very dumb.it will only be aware of a few pieces of the application and can be reused in multiple places. If a component is only aware of the data it needs and the event(s) it needs to fire when things change, it can be extremely decoupled from the rest of the application and less prone to break as the React JS application changes over time.

In a few lines of code, we can tackle real browser or server challenges with machine learning and neural networks! Here's the source code: Machine learning is a fun new(er) way to solve problems.

Once we have a trained network, we can use it to predict outcomes. In this example, we will train a neural network to distinguish between dark and light colors and pick the appropriate color of text to go over the top. To do this without machine learning, there is no single solution that will always get it right (see this blog post )
