<h2>What is a programming language?</h2>
<p>A programming language is a <b>human readable</b> set of commands to communicate between <b>machines</b> and humans. It usually comprises of a <b>set of instructions</b> for the machine to perform specific tasks.</p>
</section>
<section>
<section>
<h2>1st Generation Languages (1GLs)</h2>
<p>
<ul>
<li>machine-level language (0s and 1s)</li>
<li>no compiler (or translator) needed</li>
<li>used to program lower level functions of a system, such as drivers and interfaces with hardware</li>
<li>difficult to learn and understand errors difficult to find</li>
</ul>
</p>
<aside class="notes">
Type 's' in the presentation to bring up notes. Programmers code in <em>languages</em>. Java, Python, JS, Ruby, PHP, and Objective-C are all examples of languages. Languages are how we as humans can communicate with computers.
</aside>
</section>
<section>
<h2>2nd Generation Languages (2GLs)</h2>
<p>
<ul>
<li>Assembly languages</li>
<li>Allow for use of symbolic names</li>
<li>Can be read and written by a programmer</li>
<li>Language specific to particular machines (not portable)</li>
<li>Used in intensive processing in games, video editing, graphic manipulation/rendering</li>
</ul>
</p>
<aside class="notes">
</aside>
</section>
<section>
<h2>3rd Generation Languages (3GLs)</h2>
<p>
<ul>
<li>Words-like commands make languages more programmer friendly</li>
<li>Known as high level languages</li>
<li>Compiler or interpreter needed</li>
<li>Programs independent from computer types (portable)</li>
<li><em>Examples:</em> Fortran, COBOL, C, C++, BASIC, Pascal, Java, Javascript, PHP, Ruby, Python, Objective C</li>
</p>
<aside class="notes">
</aside>
</section>
<section>
<h2>4th Generation Languages (4GLs)</h2>
<p>
<ul>
<li>Syntax used very close to human language</li>
<li>Designed to:</li>
<ul>
<li>reduce programming effort</li>
<li>time it takes to develop software</li>
<li>cost of software development</li>
</ul>
<li>Typically used to access databases</li>
<li><em>Examples:</em> SQL and ColdFusion</li>
</ul>
</p>
<aside class="notes">
</aside>
</section>
<section>
<h2>5th Generation Languages (5GLs)</h2>
<p>
<ul>
<li>Languages used to support artificial intelligence</li>
<li><em>Example:</em> Prolog</li>
</ul>

<h2>What makes up a language?</h2>
<p>
Variables <br />
Arrays <br />
Methods, Functions <br />
Loops <br />
Conditionals <br />
</p>
<p><em>Tools in every language that let humans communicate with computers.</em></p>
<aside class="notes">
Computers need cold, hard facts and simple, unnuanced instructions: languages provide you with tools to create logic for computers including ways to store data, get data once you've stored it, manipulate data, and serve it all up to a user.
</aside>
</section>
<section>
<h2>What makes one language different from another?</h2>
<p>
<ul>
<li>Syntax</li>
<li>Usage</li>
<li>Difficulty</li>
</ul>
</p>
<p><em>What you want to build dictates what tools you should use.</em></p>
<aside class="notes">
Every language is different and better suited for some things over others. Lots of programmers know a handful of languages and will choose the language best suited to solve the problem at hand. Languages will differ from one another based on what the code you're writing looks like (called <em>Syntax</em>), when it's best to use it, and just how difficult the language is. Some languages are very difficult but what you can accomplish with them is worth the pain of having to learn a harder language.

<h2>Where are HTML and CSS?</h2>
<p>
Not programming languages<br />
Markup<br />
<em>Small pieces in a very, very big puzzle</em>
</p>
<aside class="notes">
Some of you want to learn HTML and CSS. These are not programming languages, they're something known as <em>markup</em>. Markup is a way of tagging information so that you can manipulate with a programming language. HTML and CSS are incredibly easy t learn but won't take you very far: you can build a simple web page with HTML and CSS but you can't build a web app people can log into. If learning HTML and CSS are your main goals, we can point you in the direction of some other groups that will help you learn these.

<h2>Frontend vs Backend</h2>
</section>
<section>
<h2>Frontend</h2>
<p>What the user interacts with</p>
<ul>
<li>HTML</li>
<li>CSS</li>
<li>JavaScript</li>
<li>SASS/LESS Frameworks</li>
</ul>
</section>
<section>
<h2>Backend</h2>
<p>Where you store your application logic. Concerns with launching website, maintenance, version updates etc</p>
<ul>
<li>JAVA</li>
<li>Python</li>
<li>Ruby/Ruby on Rails</li>
<li>PHP</li>
<li>NodeJS</li>
<li>Databases</li>
</ul>
</section>
<section>
<h2>Databases</h2>
<p>A structured set of data stored in a computer/machine, that is accessible in various ways</p>
<ul>
<li>Relational</li>
<ul>
<li>MSSQL</li>
<li>MYSQL</li>
<li>PostgreSQL</li>
</ul><br />
<li>Non-Relation (NoSQL)</li>

<li>MongoDB</li>
<li>CouchDB</li>
<li>Redis</li>
</ul>
</ul>
</section>
</section>
<section>
<section>
<h2>Frameworks</h2>
<p>
<ul>
<li>Programming frameworks work with languages to help you develop better and faster!</li>
<li>Frameworks are structured, maintainable, and upgradable</li>
<li>Allow programmers to save time by using generic modules in order to focus on other</li>
</ul>
</p>
<aside class="notes">
</aside>
</section>
<section>
<h2>Examples of Frameworks</h2>
<p>
<ul>
<li>Ruby on Rails (Ruby)</li>
<li>Django (Python)</li>
<li>Backbone/Ember/Angular (JavaScript)</li>
<li>CakePHP (PHP)</li>
<li>Symfony (PHP)</li>
<li>Sitecore (.NET)</li>
</ul>
</p>
<aside class="notes">
The good news about coding is that lots of developers contribute to <em>open-source</em> - meaning that they release code they've written to make it easier to build apps. These are known as <em>frameworks</em> and tons of them exist and are always language-specific. You have probably heard of <em>Ruby on Rails</em>, which helps people build web apps using Ruby. There's also <em>Angular</em>, which helps people build web apps with Javascript. Part of building an app means researching tools and deciding whether or not you think they'll help you or make your life more difficult.

<h2>What We Build With Code</h2>
<p>
<ul>
<li>iPhone apps</li>
<li>Android apps</li>
<li>Web apps</li>
<li>Libraries</li>
<li>Frameworks</li>
<li>Games</li>
</ul>
</p>
<aside class="notes">
Some of the things that we build include apps, website sites, web aps, libraries, and frameworks. Apps will run on your phone or on a tablet. A website or a web app can be accessed on the internet with a URL. A webapp might do similar things to an app on your phone, meaning users can log in and save data. You might build a library, which would be tiny packets of code that other poeple find useful and can use in their own projects. You might build a framework, which can help other people build their own applications. You might build a computer program that others can download onto their computers. The sky's the limit if you have an idea and a willingness to learn.
