Learn to Code: The Full Beginner's Guide
If you've been looking to learn how to code, we can help you get started. Here are 4.5 lessons on the basics and extra resources to keep you going. Variables and Basic Data Types In our first lesson we're going to be taking a look at how to store different kinds of variables Working With Variables Now that you know a thing or two about basic variables and data types, we're going to play around with them and see how they work. Arrays and Logic Statements In this lesson we're going to start with arrays, which are a more complex type of variable, and then move on to for loops and if statements, which let you add conditional logic to your code. This is where things get tough, but also very cool.Want to learn how to code but don't know where to start? We've got you covered. We'll be teaching you the basics all week, and here's your first lesson. Previously we've provided you with some resources for learning to code and given you a broad overview of the process , but now it's time to get down to business: We're offering a short 101 course, step by step. You can't learn to code overnight (or in a week), but we've broken up the basics into a few lessons that will be released as the first four parts in our brand new Lifehacker Night School series.
Learn How to Code Part I: Variables and Basic Data Types
In our second "Learn to Code" lesson, we'll be taking a look at how to actually work with the variables and data types we learned about in the first lesson . Get excited—it's time to put your new knowledge to work! These lessons work best with the video, which you can see above, but we're also providing text for reference below. Even if you do prefer to read, the videos will be more explicit and demonstrate how to do everything we're discussing. If the text seems a bit too complicated, be sure to watch the video. We're going to create a variable statement so you can see how useful variables can be.
Learn to Code Part II: Working With Variables
You've mastered the basics of variables and made it half way through our course, but are you up to the challenge of arrays and logic statements? Of course you are. Let's get started! These lessons work best with the video, which you can see above, but we're also providing text for reference below.
Learn to Code Part III: Arrays and Logic Statements
If you've made it this far in our programming lessons, you've arrived at the reward. Today we're learning about functions and then we're going to make a very simple guessing game. These lessons work best with the video, which you can see above, but we're also providing text for reference below.
Learn to Code Part IV: Understanding Functions and Making a Guessing Game
Congratulations, you've learned the basics of programming! That's wonderful, but you'd better not go out into the world and write crappy code. Before we set you free, here are some best practices and good things to keep in mind. Best Practices Comment Your Code and Comment It Well

If you're a web developer, you've probably had to make a user account system. The most important aspect of a user account system is how user passwords are protected. User account databases are hacked frequently, so you absolutely must do something to protect your users' passwords if your website is ever breached. The best way to protect passwords is to employ salted password hashing . This page will explain how to do it properly.

Course Description Although the World-Wide Web was initially conceived as a vehicle for delivering documents, it is now being used as a platform for sophisticated interactive applications, displacing the traditional mechanism of installable binaries. Web-based applications offer numerous advantages, such as instant access, automatic upgrades, and opportunities for collaboration on a massive scale. However, creating Web applications requires different approaches than traditional applications and involves the integration of numerous technologies. This class will introduce you to the Web technologies and give you experience creating Web applications. In the process you will learn about markup languages, scripting languages, network protocols, interactive graphics, event-driven programming, and databases, and see how they all work together to deliver exciting applications.

In production and development, open source is a philosophy , or pragmatic methodology that promotes free redistribution and access to an end product's design and implementation details [ citation needed ] . Before the phrase open source became widely adopted, developers and producers used a variety of terms for the concept; open source gained hold with the rise of the Internet , and the attendant need for massive retooling of the computing source code . [ 1 ] Opening the source code enabled a self-enhancing diversity of production models, communication paths, and interactive communities. [ 2 ] The open-source software movement arose to clarify the environment that the new copyright , licensing , domain , and consumer issues created. [ citation needed ] Generally, open source refers to a program in which the source code is available to the general public for use and/or modification from its original design.
