<h2>What is the world wide web?</h2>
<img class="fragment" src="images/client-server.png" alt="" />
</section>
<section>
<h3>Home and daily life of a web site</h3>
<p class="left-align">A typical web site will live or is "hosted" on a web server. Web servers are often large computers connected to a network.</p>
<ul>
<li class="fragment">Type a web site address into the address bar</li>
<li class="fragment">DNS connects you to the hosting server</li>

<section>
<h3>Clients vs. Servers</h3>
<div class="left-align">
<p class="fragment">Clients make requests, servers fulfill them (usually).</p>
<p class="fragment">For our web discussions, client = browser, but search engine crawlers, command line interfaces, and other applications can also behave as clients.</p>
<p class="fragment">While any type of computer can be used as a server, they are generally larger and more powerful than others.</p>
</div>

</ul>
</section>
</section>
<section>
<h2>Java != JavaScript</h2>
<div style="width: 48%; margin-right: 2%; float: left; text-align: left;">
<p>Java:</p>
<ul class="fragment">
<li>Server-side</li>
<li>Object-oriented</li>

<li class="fragment">Hosting and a domain name
<ul class="fragment">
<li>Domain name registration should not cost more than $15/yr</li>

</ul>
</li>
<li class="fragment">Whether to build it yourself or hire someone</li>
</ul>
</section>
<section>
<section>
<h3>User Experience & Information Architecture</h3>

<h3>WYSIWYG vs. hand-coding</h3>
<ul>
<li>WYSIWYG code editors make general assumptions about what you intended to write which often is not accurate or best</li>
<li class="fragment">They make the job of professionals <em>much</em> more difficult when the code is written poorly and filled with junk</li>
<li class="fragment">To truly understand what you are building, you need to learn the fundamental components</li>
<li class="fragment">Once you know how to code by hand, there are no limits to what you can build!</li>
</ul>
</section>
<section>
<section>
<h3>What languages to use</h3>
<p class="fragment">That depends...</p>
<ul>
<li class="fragment">HTML and CSS will almost certainly be used</li>
<li class="fragment">JavaScript may be used for interactivity</li>
<li class="fragment">Server-side languages will likely be used for any data storage or retrieval</li>
</ul>
</section>
<section>
<h2>Demo: How'd they do that?</h2>
<a href="http://unitedmakers.com/" target="_blank">Fancy flowed text</a><br />
<a href="http://filmstartheband.com/" target="_blank">Onclick expansion</a><br />
<a href="http://www.qvc.com/" target="_blank">Slideshow spelunking</a>
<aside class="notes">
<ul>
<li>Show how to use browser inspection</li>
<li>Show how to dissect a couple small interesting components</li>
<li>Obviously, swap these out for whatever examples work for you</li>
</ul>

<h3>Server-side languages: What are the differences?</h3>
<ul>
<li>The main difference is syntax</li>
<ul>
<li>the set of rules that define the combinations of symbols that are considered to be correctly structured programs in that language</li>
</ul>
<li class="fragment">They have slightly different strengths and philosophies</li>
<li class="fragment">Which you choose to use will depend on
<ul>
<li>What you are familiar with or want to learn</li>
<li>What your host supports</li>
<li>Community and documentation</li>
</ul>
</li>

<h3>Tools of the trade</h3>
<p class="left-align">To build your web site, you will probably need:</p>
<ul>
<li class="fragment">A simple text editor or code editor such as SublimeText, Notepad, or TextWrangler to write your code. Many can be found for free.</li>
<li class="fragment">A web browser such as Chrome, Firefox, or Safari to test your code. All popular modern browsers are free.</li>
</ul>
</section>
<section>
<h3>Tools of the trade</h3>
<p class="left-align">You will also need:</p>
<ul>
<li class="fragment">An FTP (file transfer protocol) client such as WinSCP, Cyberduck, or CoffeeCup FTP to get files from your computer to the server. Many are free.</li>
<li class="fragment">Optionally, an image editor such as IrfanView, Gimp, or Photoshop to edit images which will be used on the web site. Some are available for free.</li>

<h3>How to hire a developer</h3>
<p class="left-align">Remember the three Rs:</p>
<ul>
<li class="fragment"><strong>References</strong>: Talk to people who have worked with the developer before. Were they prompt? Pleasant? Forthright?</li>
<li class="fragment"><strong>Requirements</strong>: Can they do the work that needs to be done. Ask for samples of their prior work and ask exactly which parts of the process they were responsible for. Design? UX? DB architecture? QA?</li>
<li class="fragment"><strong>Reality</strong>: If it sounds too good to be true, it probably is. This website will be a reflection of you, either personally or professionally. Hire someone you feel will be invested in a job well done.</li>
