i have sampled (univariate) data - clock driving sampling process inaccurate - resulting in random slip of (less than) 1 sample every 30. more accurate clock @ approximately 1/30 of frequency provides reliable samples same data ... allowing me establish estimate of clock drift. i looking interpolate sampled data correct 'fit' high frequency data low-frequency. need 'real time' - no more latency of few low-frequency samples. i recognise there wide range of interpolation algorithms - and, among i've considered, spline based approach looks promising data. i'm working in python - , have found scipy.interpolate package - though see no obvious way use 'stretch' n samples correct small timing error. overlooking something? i interested in pointers either suitable published algorithm, or - ideally - python library function achieve sort of transform. supported scipy (or else)? update... i'm beginning realise what, @ first, seemed trivial pr

i impressed flexibility of yii events. new yii , want know how pass parameters yii event handlers? //i have onlogin event defined in login model public function onlogin($event) { $this->raiseevent("onlogin", $event); } i have login handler defined in handler class. event handler method takes parameter: function loginhandler($param1) { ... } but here, confused how pass parameter login event handler: //i attach login handler this. $loginmodel->onlogin = array("handlers", "loginhandler"); $e = new cevent($this); $loginmodel->onlogin($e); am doing wrong? there approach this? now have answer own question. cevent class has public property called params can add additional data while passing event handler. //while creating new instance of event $params = array("name" => "my name"); $e = new cevent($this, $params); $loginmodel->onlogin($e); //adding second parameter allow me add data can accessed
