attribute selectors! input[type=date]{color: red; } $('input[type=date]); twitter: bphogan email: brianhogan at napcs.com

modernizr http://www.modernizr.com/ twitter: bphogan email: brianhogan at napcs.com

placeholder and autofocus twitter: bphogan email: brianhogan at napcs.com

Placeholder <label id='email'>Emaill</label> <input id='email' placeholder="username@google.com" type='email'> twitter: bphogan email: brianhogan at napcs.com

video <video src="movie.m4v" controls="controls"> <p>Your browser does not support the video tag.</p> </video> twitter: bphogan email: brianhogan at napcs.com

To play video, you need a container and a codec. twitter: bphogan email: brianhogan at napcs.com

H264 vs Theora vs WebM twitter: bphogan email: brianhogan at napcs.com

Firefox only plays Theora and WebM twitter: bphogan email: brianhogan at napcs.com

Chrome plays all. Sometimes. twitter: bphogan email: brianhogan at napcs.com

Google, Apple, and Microsoft are H264 licensees twitter: bphogan email: brianhogan at napcs.com

Mozilla will support WebM. So will IE9. twitter: bphogan email: brianhogan at napcs.com

So will Youtube. twitter: bphogan email: brianhogan at napcs.com

So will Flash Player! twitter: bphogan email: brianhogan at napcs.com

Safari plays H264. So do all of Apple’s iThingies. twitter: bphogan email: brianhogan at napcs.com

Patent-free or not, content makers will not encode videos twice. twitter: bphogan email: brianhogan at napcs.com

CONTROVERSIAL TOPIC AHEAD! twitter: bphogan email: brianhogan at napcs.com

The Adult industry will decide the winner. twitter: bphogan email: brianhogan at napcs.com

They want iPad users. twitter: bphogan email: brianhogan at napcs.com

They’re providing H264 + HTML5 video. twitter: bphogan email: brianhogan at napcs.com

Also, H264 will remain royalty-free for free content. twitter: bphogan email: brianhogan at napcs.com

Fallback? Video For Everyone! http://camendesign.com/code/video_for_everybody twitter: bphogan email: brianhogan at napcs.com

HTML5 Audio twitter: bphogan email: brianhogan at napcs.com

<audio id="drums" controls="true"> <source src="sounds/ogg/drums.ogg" type="audio/ogg"> <source src="sounds/mp3/drums.mp3" type="audio/mpeg"> <a href="sounds/mp3/drums.mp3">Download drums.mp3</a> </audio> twitter: bphogan email: brianhogan at napcs.com

MP3 vs AAC vs Vorbis twitter: bphogan email: brianhogan at napcs.com

Why bother? twitter: bphogan email: brianhogan at napcs.com

CSS3 Columns! twitter: bphogan email: brianhogan at napcs.com

Got content? <div id="example"> <h1>Splitting an element into columns</h1> <div class="column"> <p>Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore.</p> <p>Et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum. </p> </div> </div> twitter: bphogan email: brianhogan at napcs.com

Just split it! .column { -moz-column-width: 200px; -webkit-column-width: 200px; -moz-column-gap: 20px; -webkit-column-gap: 20px; -moz-column-rule: 1px solid #ddccb5; -webkit-column-rule: 1px solid #ddccb5; } twitter: bphogan email: brianhogan at napcs.com

Fallback support using jQuery Columnizer plugin. http://welcome.totheinter.net/columnizer-jquery-plugin/ http://welcome.totheinter.net/2008/07/22/multi-column-layout-with-css-and-jquery/ twitter: bphogan email: brianhogan at napcs.com

CSS3 Pseudo Classes twitter: bphogan email: brianhogan at napcs.com

Fallback? Make a regular form. twitter: bphogan email: brianhogan at napcs.com

Local Storage twitter: bphogan email: brianhogan at napcs.com

Remember when cookies were awesome? twitter: bphogan email: brianhogan at napcs.com

localStorage.setItem("background_color", “#fff”); var bgcolor = localStorage.getItem("background_color"); twitter: bphogan email: brianhogan at napcs.com

Fallback? Detect and use cookies. twitter: bphogan email: brianhogan at napcs.com

On Webkit? Web SQL Storage twitter: bphogan email: brianhogan at napcs.com

Works in IE9 now. twitter: bphogan email: brianhogan at napcs.com

Websockets twitter: bphogan email: brianhogan at napcs.com

Polling is costly. twitter: bphogan email: brianhogan at napcs.com

Websockets are true client/server. twitter: bphogan email: brianhogan at napcs.com

require 'rubygems' require 'web_socket' require 'json' class TimeServer < WebSocket::Server Websocket Server def on_connect puts "Connection Accepted" @timer = EM.add_periodic_timer(5, EM.Callback(self, :sync_time)) end def on_disconnect puts "Connection released" EM.cancel_timer @timer end def on_receive msg end def sync_time puts "Hi" send_message({ :time => Time.now }.to_json) end end EM.epoll = true if EM.epoll? EM.kqueue = true if EM.kqueue? EM.set_descriptor_table_size(10240) EM.run do EM.start_server "0.0.0.0", 8000, TimeServer end twitter: bphogan email: brianhogan at napcs.com

Talk to it with Javascript var webSocket = new WebSocket('ws://localhost:8000/time'); webSocket.onopen = function(event){ document.getElementById('time').innerHTML = 'waiting for socket'; }; webSocket.onmessage = function(event){ var object = JSON.parse(event.data); document.getElementById('time').innerHTML = object.time; }; webSocket.onclose = function(event){ document.getElementById('time').innerHTML = 'socket closed'; }; twitter: bphogan email: brianhogan at napcs.com

Older browsers? Flash Sockets http://github.com/gimite/web-socket-js twitter: bphogan email: brianhogan at napcs.com

ARIA twitter: bphogan email: brianhogan at napcs.com

Stuff updates on the screen all the time. twitter: bphogan email: brianhogan at napcs.com

updatable window <h3>Tasks</h3> <form id="task_form"> <label>Task <input type="text" id="task" name="task" value=""> </label> <input type="submit" value="Add"> </form> <ul aria-live="polite" id="tasks"> </ul> twitter: bphogan email: brianhogan at napcs.com
