<h2>Agenda</h2>
<ul>
<li>What is Orion?</li>
<li>A glance at web technologies</li>
<li>More about Orion</li>
<li>Demos</li>
<li>Discussion and Q&A</li>

<h2>Goals of Orion</h2>
<ul>
<li>Build developer tooling that works in a browser,</li>
<li>at web scale,</li>
<li>integrating well with existing tools that exist on the web,</li>
<li>based on well - proven web architectures - REST, HTTP, JSON,
OAuth, OpenID, and others.</li>
</ul>
<p id="footer">
</div>
<div>
<p id="header">
<h2>Use Strengths of the Web</h2>
<ul>
<li>zero install on the client</li>
<li>simple connectivity - links</li>
<li>trivial update mechanism</li>
<li>powerful rendering engine</li>
<li>look and feel easy to adapt</li>
<li>large, active community</li>
<li>innovation by everyone</li>
<li>no central "IDE"</li>
<li>artifacts all over the web</li>
<li>highly distributed content</li>
<li>refresh the page</li>
<li>scalable computing power</li>
</ul>
<p id="footer">
</div>
<div>
<p id="header">
<h2>Why work on this now?</h2>
<ul>
<li>There are other online IDEs already, extremely high rate of
innovation in online tools for web development</li>
<li>We need to start now, learn, fail, try again, in order to
become a player in this space</li>
<li>We (IBM) would like to see a community to form around this
forms at Eclipse, and are contributing a seed</li>
</ul>

<h2>A Glance at Web Architectures - REST</h2>
<p>An important concept in REST is the existence of resources
(sources of specific information), each of which is referenced with a
global identifier (e.g., a URI in HTTP). In order to manipulate these
resources, components of the network (user agents and origin servers)
communicate via a standardized interface (e.g., HTTP) and exchange
representations of these resources (the actual documents conveying
the information).</p>

<h2>A Glance at Web Architectures</h2>
<ul>
<li><b>HTTP</b> - a networking protocol for distributed,
collaborative, hypermedia information systems. HTTP is the
foundation of data communication for the WWW</li>
<li><b>Ajax</b> - a group of interrelated web developmentt
methods used on the client-side to create interactive web
applications. With Ajax, web applications can retrieve data from the
server asynchronously in the background</li>
<li><b>JSON</b> - a lightweight text-based open standard
designed for human-readable data interchange</li>
<pre class="brush: xml">
<value>
<array>
<data>
<value><int>3</int></value>
<value><string>three</string></value>
</data>
</array>
</value>
</pre>
<pre class="brush: js">
{
[3, "three"]
}
</pre>
<li><b>OpenID</b> - a standard that describes how users can
authenticated in a decentralized manner</li>
<li><b>OAuth</b> - an open standard for authorization, which
allows users to share their private resources stored on one site
with another site without having to hand out their credentials</li>
</ul>

<h2>Assumptions</h2>
<ul>
<li>Software development in a browser
<ul>
<li>editing</li>
<li>navigating folders</li>
<li>searching</li>
<li>working with SCM</li>
</ul>
</li>
<li>Set of linked web pages, <b>NOT an IDE running in a
browser</b>
<ul>
<li>easy to integrate other functionality even if hosted on
different servers</li>
</ul>
</li>
</ul>

<h2>Why Not an IDE in a Browser?</h2>
<a href="http://cloud9ide.com/signin.html">Cloud9 IDE</a><br>
<ul>
<li>tabs</li>
<li>menu items</li>
<li>files tree</li>
<li>dialogs</li>

<div>
<p id="header">
<h2>Context: Already in a Browser</h2>
<ul>
<li>Bug tracking (<a
href="https://bugs.eclipse.org/bugs/show_bug.cgi?id=341953">Bugzilla</a>,
JIRA, Trac, Lighthouse, Rational RTC)</li>
<li>Builds (<a href="https://hudson.eclipse.org/hudson/?">Hudson</a>/Jenkins)</li>
<li>Code review (Bugzilla, <a
href="http://egit.eclipse.org/r/#change,3008">Gerrit</a>, GitHub)</li>
<li>Documentation (<a

<h2>What's Missing? Not Much</h2>
<ul>
<li>Code editor</li>
<li>Navigator</li>
<li>Work with SCM (commit, compare, merge, etc)</li>
<li>Indexing - full text search</li>
<li>Unit tests</li>
<br>
<br>
<li>Initial focus on web developers working on client-side
JavaScript, HTML, CSS</li>
</ul>
<p id="footer">

<h2>Design Principles</h2>
<ul>
<li>Regular hyperlinks, back button, bookmarking, link sharing</li>
<li>Functionality on separate pages: <b>Page = Task +
Resource</b>
</li>
<li>Performant and Lightweight. Speed trumps power.</li>
<li>Components should have value on their own.</li>
<li>Low barrier of entry for adopters. Don't require technology
buy-in.</li>

"compression" of images</li>
<li><a href="http://spritegen.website-performance.org/">CSS
Sprite Generator</a>
