Por ahora sólo funciona en Google, pero un código de ejemplo sería el siguiente:

if ("WebSocket" in window) {
  var ws = new WebSocket("ws://websockets.org:8787"); //this service bounces messages back
  ws.onopen = function() {
    // Web Socket is connected. You can send data by send() method.
    ws.send("message to send"); 
  };
  ws.onmessage = function (evt) { var received_msg = evt.data; alert(evt.data);  };
  ws.onclose = function() { /* websocket is closed.*/alert("WebSocket Closed!"); };
}else{
  // the browser doesn't support WebSocket.
  alert("Websocket is not supported in your browser");
}

Me hizo gracia esta frase: “NoSQL is for very smart people who need a very sharp knife.” espero un día cumplir ambas condiciones

INSERT IGNORE 
  INTO tabla 
    (id, valor, ...) 
  VALUES 
    (25, 'valor, ...) 

Cada día aprendo algo nuevo, aunque a veces deberían darme con la Biblia de MySQL (775 páginas) en la cabeza por no conocer antes esto.

$maxChildren = 4;
$numChildren = 0;
foreach($unitsOfWork as $unit) {
  $pids[$numChildren] = pcntl_fork();
  if(!$pids[$numChildren]) {
    // do work
    doWork($unit);

Ahora que el NoSQL es una alternativa a las bases de datos relacionales, esta librería nos ayudará bastante a la hora de realizar nuestra aplicación, ya que el código es bastante sencillo.

class myBlogDocument extends phpillowDocument { 
  protected static $type = 'blog_entry'; 
  protected $requiredProperties = array( 'title', 'text', ); 
  public function __construct() { 
    $this->properties = array( 
      'title' => new phpillowStringValidator(), 
      'text' => new phpillowTextValidator(), 
      'comments' => new phpillowDocumentArrayValidator( 'myBlogComments' )
    ); 
    parent::__construct(); 
  } 
  protected function generateId() { 
    return $this->stringToId( $this->storage->title ); 
  } 
  protected function getType() { 
    return self::$type; 
  } 
}

Una alternativa a tener en cuenta, yo personalmente uso bastante var_dump y a veces es un poco lío seguir en debug de objetos grandes.
