+<h1>Beginnings</h1>
+<ul>
+<li>Unsatisfied with existing solutions</li>
+<li>Wanted a mix of Webmachine and Misultin<ul>
+ <li>With binaries</li>
+ <li>And dynamic "listeners"</li>
+ <li>And some icing on top</li>
+</ul></li>
+<li>First commit on March 7th 2011</li>
+</ul>
+</div>
+
+
+<div class="slide">
+<h1>Initial goals</h1>
+<ul>
+<li>Binary</li>
+<li>Dynamic listeners</li>
+<li>Low latency and memory usage</li>
+<li>One Erlang process per connection</li>
+<li>Small codebase</li>
+<li>Clean Erlang code</li>
+</ul>
+</div>
+
+
+<div class="slide">
+<h1>Initial reactions</h1>
+<ul>
+<li>Encouraging</li>
+<li>Community started growing slowly</li>
+<li>People started recommending Cowboy to others</li>
+<li>First Cowboy talk at EUC 2011 had a full room</li>
+</ul>
+</div>
+
+
+<div class="slide">
+<h1>Misultin's help</h1>
+<ul>
+<li>Great project</li>
+<li>Still unmatched in usability</li>
+<li>Development stopped in favor of Cowboy</li>
+<li>Boosted Cowboy's adoption</li>
+<li>My thanks go to Roberto Ostinelli</li>
+</ul>
+</div>
+
+
+<div class="slide">
+<h1>The road to stable</h1>
+<ul>
+<li>Few changes for about 6 months</li>
+<li>Spent a lot of time figuring things out</li>
+<li>Then spent a lot more time getting things done</li>
+<li>A few improvements remain to be done</li>
+</ul>

+<h1>New goals</h1>
+<ul>
+<li>Complete HTTP stack</li>
+<li>Complete support for the modern web</li>
+<li>Good documentation</li>
+<li>Stable version</li>
+<li>Target non-Erlang developers</li>
+</ul>
+</div>
+
+
+<div class="slide">
+<h1>New conventions</h1>
+<ul>
+<li>Everything is a binary, including method and header names</li>
+<li>HTTP header names are lowercase</li>
+<li>cowboy_http_req -> cowboy_req</li>
+<li>cowboy_http_* -> cowboy_*</li>
+</ul>
+</div>
+
+
+<div class="slide">
+<h1>HTTP</h1>
+<ul>
+<li>Improved HTTP/1.1 and HTTP/1.0 support</li>
+<li>Built-in response compression</li>
+<li>Built-in parsing of HTTP headers</li>
+<li>Much faster request body streaming code</li>
+<li>Properly detect socket close in long-polling</li>
+</ul>
+</div>
+
+
+<div class="slide">
+<h1>HTTP Req</h1>
+<ul>
+<li>Normalized cowboy_req API</li>
+<li>Access: {Value, Req}</li>
+<li>Action: {Result, Req} | {Result, Value, Req} | {error, atom()}</li>
+<li>Modification: Req</li>
+<li>Question: boolean()</li>
+</ul>
+</div>
+
+
+<div class="slide">
+<h1>Websocket</h1>
+<ul>
+<li>Fully passes the Autobahn test suite</li>
+<li>Much faster at processing frames</li>
+<li>Text frames now required to be valid UTF-8</li>
+</ul>
+</div>
+
+
+<div class="slide">
+<h1>REST</h1>
+<ul>
+<li>Better error reporting</li>
+<li>PATCH method support</li>
+<li>Still experimental, no documentation</li>
+<li>Widely adopted by users</li>
+</ul>
+</div>
+
+
+<div class="slide">
+<h1>More powerful routing</h1>
+<ul>
+<li>Routes must now be compiled</li>
+<li>Nicer string-based syntax</li>
+<li>Constraints: apply functions on bound values</li>
+<li>Allows distinguishing between these two:<ul>
+ <li>/api/42/add</li>
+ <li>/api/blue/add</li>
+</ul></li>
+</ul>
+</div>
+
+
+<div class="slide">
+<h1>Middlewares</h1>
+<ul>
+<li>Hook code at any point in request handling</li>
+<li>Replace routing or handling components of request processing</li>
+<li>Not WSGI</li>
+<li>WSGI: data centric, chain request, then reverse chain response</li>
+<li>Cowboy: chain of execution, only chain request, response happens at any point</li>
+</ul>
+</div>
+
+
+<div class="slide">
+<h1>Documentation</h1>
