• Seems doctrine listener is not fired

  - by Roel Veldhuizen

  Got a service which should be executed the moment an object is persisted. Though, I think the code looks like it should work, it doesn't. I configured the service like the following yml. services: bla_orm.listener: class: Bla\OrmBundle\EventListener\UserManager arguments: [@security.encoder_factory] tags: - { name: doctrine.event_listener, event: prePersist } The class: namespace Bla\OrmBundle\EventListener; use Doctrine\ORM\Event\LifecycleEventArgs; use Bla\OrmBundle\Entity\User; class UserManager { protected $encoderFactory; public function __construct(\Symfony\Component\Security\Core\Encoder\EncoderFactoryInterface $encoderFactory) { $this->encoderFactory = $encoderFactory; } public function prePersist(LifecycleEventArgs $args) { $entity = $args->getEntity(); if ($entity instanceof User) { $encoder = $this->encoderFactory ->getEncoder($entity); $entity->setSalt(rand(10000, 99999)); $password = $encoder->encodePassword($entity->getPassword(), $entity->getSalt()); $entity->setPassword($password); } } } Symfony version: Symfony version 2.3.3 - app/dev/debug Output of

place though. At another part of the code the lister seems to be invoked. Though, there are both Controller types and both us $em->persist($something); $em->flush(); to save the changes. I would expect that in both cases the listener is invoked.

  Hi all! have problems with mouseover in Mozilla and Chrome after making it work in IE, for sure I can tell you that my code woked perfectly in Chrome at least, cause thats my default browser and I used it for debuging when creating the javascipt and it worked nicely... until I tried to make it work in IE too. Here I post the full code of the webpage I'm having trouble with. <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebbShop.aspx.cs" Inherits="FSwebportal.WebbShop" %> .prodShow{width: 100%; text-align:center;border:0; float:right; position:inherit; padding-left:310px;} prodFollow{display:block; width:100%; height:100%; position:fixed; overflow:hidden;} orderSett{display:block; position:relative; float:left; padding-top:inherit;} .ShowBig{width:290px;height:290px; padding-top:10px;} .pTb{width:50px;} .order{background-color:Transparent;margin:3px;} .txtArea{border:0;overflow:auto;width:200px;height:100px;} .prodRow{background-image:url("produktbakgrund.png"); background-repeat:repeat;} .row{background-color:Transparent;width:100%;margin: 0px auto;display:inline-table;} .col{background-color:Transparent;width:100%;margin:3px;} <div id="prodFollow"> <table id="dumbTable"> <tr> <td> <img id="sideImg" class="ShowBig" src="" alt=""/> </td> </tr> <tr> <td> <h3><b>Specifikationer:</b></h3> <select name=""> </select> </td> </tr> </table> </div> <table id="itemList" class="prodShow" cellspacing="0"> <thead> <tr class="prodRow"> <th>Bild</th> <th>Förklaring</th> <th>Artikelnummer</th> <th>Pris</th> </tr> </thead> </table> <script type="text/javascript"> function appendRow() { var tbl = document.getElementById('itemList'); var len = <%= aspInfo.Count %>; var arr = new Array(len); var currIndex = 0; var imgID=0; <% for (int x = 0; x < aspInfo.Count; x++) { Response.Write("arr["+x+"]= '"+ aspInfo[x]+"';"); } %> for(row =0; row < arr.length/4;row++) { var rad = tbl.insertRow(tbl.rows.length); rad.setAttribute('class','prodRow'); for (c = 0; c < tbl.rows[row].cells.length; c++) { if(c < 1) { createCell(rad.insertCell(c), arr[currIndex], 'col',imgID); imgID++; } else { if(c < 3) { createCell(rad.insertCell(c),"<Label class=txtArea>" + arr[currIndex] + "</Label>", 'row',imgID); } else { createCell(rad.insertCell(c),"<Label class=txtArea>" + arr[currIndex] + " SKR</Label><br>Antal:<input type=text class=pTb /><input type=button width=100px value='Lägg i varukorg'></input>", 'order',imgID); } } currIndex++; } } } function createCell(cell, text, style,imgID) { if (style == 'col') { var arrLen = <% = largeImg.Count %>; var imgArr = new Array(arrLen); <% for (int x = 0; x < largeImg.Count; x++) { Response.Write("imgArr["+x+"]= '"+ largeImg[x]+"';"); } %> var div = document.createElement('div'); div.setAttribute('class', style); div.setAttribute('className', style); div.innerHTML = "<a href='#'><img id='" + imgID + "' src='" + text + "' onmouseover=javascript:onImg('" + imgArr[imgID] + "') border='0' alt='Animg' /></a>"; cell.appendChild(div); } else { var div = document.createElement('div'); div.setAttribute('class', style); div.setAttribute('className', style); div.innerHTML = text; cell.appendChild(div); } } </script> <script type="text/javascript" language="javascript"> function onImg(bigImg) { var img = document.getElementById('sideImg#'); img.src = bigImg; alert(img.src.toString()); } </script> </form> hope you guys can solve it for me, going mad! best regards David

• Issues with HLSL and lighting

  - by numerical25

  I am trying figure out whats going on with my HLSL code but I have no way of debugging it cause C++ gives off no errors. The application just closes when I run it. I am trying to add lighting to a 3d plane I made. below is my HLSL. The problem consist when my Pixel shader method returns the struct "outColor" . If I change the return value back to the struct "psInput" , everything goes back to working again. My light vectors and colors are at the top of the fx file // PS_INPUT - input variables to the pixel shader // This struct is created and fill in by the // vertex shader cbuffer Variables { matrix Projection; matrix World; float TimeStep; }; struct PS_INPUT { float4 Pos : SV_POSITION; float4 Color : COLOR0; float3 Normal : TEXCOORD0; float3 ViewVector : TEXCOORD1; }; float specpower = 80.0f; float3 camPos = float3(0.0f, 9.0, -256.0f); float3 DirectLightColor = float3(1.0f, 1.0f, 1.0f); float3 DirectLightVector = float3(0.0f, 0.602f, 0.70f); float3 AmbientLightColor = float3(1.0f, 1.0f, 1.0f); /*************************************** * Lighting functions ***************************************/ /********************************* * CalculateAmbient - * inputs - * vKa material's reflective color * lightColor - the ambient color of the lightsource * output - ambient color *********************************/ float3 CalculateAmbient(float3 vKa, float3 lightColor) { float3 vAmbient = vKa * lightColor; return vAmbient; } /********************************* * CalculateDiffuse - * inputs - * material color * The color of the direct light * the local normal * the vector of the direct light * output - difuse color *********************************/ float3 CalculateDiffuse(float3 baseColor, float3 lightColor, float3 normal, float3 lightVector) { float3 vDiffuse = baseColor * lightColor * saturate(dot(normal, lightVector)); return vDiffuse; } /********************************* * CalculateSpecular - * inputs - * viewVector * the direct light vector * the normal * output - specular highlight *********************************/ float CalculateSpecular(float3 viewVector, float3 lightVector, float3 normal) { float3 vReflect = reflect(lightVector, normal); float fSpecular = saturate(dot(vReflect, viewVector)); fSpecular = pow(fSpecular, specpower); return fSpecular; } /********************************* * LightingCombine - * inputs - * ambient component * diffuse component * specualr component * output - phong color color *********************************/ float3 LightingCombine(float3 vAmbient, float3 vDiffuse, float fSpecular) { float3 vCombined = vAmbient + vDiffuse + fSpecular.xxx; return vCombined; } //////////////////////////////////////////////// // Vertex Shader - Main Function /////////////////////////////////////////////// PS_INPUT VS(float4 Pos : POSITION, float4 Color : COLOR, float3 Normal : NORMAL) { PS_INPUT psInput; float4 newPosition; newPosition = Pos; newPosition.y = sin((newPosition.x * TimeStep) + (newPosition.z / 3.0f)) * 5.0f; // Pass through both the position and the color psInput.Pos = mul(newPosition , Projection ); psInput.Color = Color; psInput.ViewVector = normalize(camPos - psInput.Pos); return psInput; } /////////////////////////////////////////////// // Pixel Shader /////////////////////////////////////////////// //Anthony!!!!!!!!!!!

• Problems Allocating Objects of Derived Class Where Base Class has Abstract Virtual Functions

  - by user1743901

  I am trying to get this Zombie/Human agent based simulation running, but I am having problems with these derived classes (Human and Zombie) who have parent class "Creature". I have 3 virtual functions declared in "Creature" and all three of these are re-declared AND DEFINED in both "Human" and "Zombie". But for some reason when I have my program call "new" to allocate memory for objects of type Human or Zombie, it complains about the virtual functions being abstract.

• Conceal packet loss in PCM stream

  - by ZeroDefect

  I am looking to use 'Packet Loss Concealment' to conceal lost PCM frames in an audio stream. Unfortunately, I cannot find a library that is accessible without all the licensing restrictions and code bloat (...up for some suggestions though). I have located some GPL code written by Steve Underwood for the Asterisk project which implements PLC. There are several limitations; although, as Steve suggests in his code, his algorithm can be applied to different streams with a bit of work. Currently, the code works with 8kHz 16-bit signed mono streams. Variations of the code can be found through a simple search of Google Code Search. My hope is that I can adapt the code to work with other streams. Initially, the goal is to adjust the algorithm for 8+ kHz, 16-bit signed, multichannel audio (all in a C++ environment). Eventually, I'm looking to make the code available under the GPL license in hopes that it could be of benefit to others... Attached is the code below with my efforts. The code includes a main function that will "drop" a number of frames with a given probability. Unfortunately, the code does not quite work as expected. I'm receiving EXC_BAD_ACCESS when running in gdb, but I don't get a trace from gdb when using 'bt' command. Clearly, I'm trampimg on memory some where but not sure exactly where. When I comment out the *amdf_pitch* function, the code runs without crashing... int main (int argc, char *argv[]) { std::ifstream fin("C:\\cc32kHz.pcm"); if(!fin.is_open()) { std::cout << "Failed to open input file" << std::endl; return 1; } std::ofstream fout_repaired("C:\\cc32kHz_repaired.pcm"); if(!fout_repaired.is_open()) { std::cout << "Failed to open output repaired file" << std::endl; return 1; } std::ofstream fout_lossy("C:\\cc32kHz_lossy.pcm"); if(!fout_lossy.is_open()) { std::cout << "Failed to open output repaired file" << std::endl; return 1; } audio::PcmConcealer Concealer; Concealer.Init(1, 16, 32000); //Generate random numbers; srand( time(NULL) ); int value = 0; int probability = 5; while(!fin.eof()) { char arr[2]; fin.read(arr, 2); //Generate's random number; value = rand() % 100 + 1; if(value <= probability) { char blank[2] = {0x00, 0x00}; fout_lossy.write(blank, 2); //Fill in data; Concealer.Fill((int16_t *)blank, 1); fout_repaired.write(blank, 2); } else { //Write data to file; fout_repaired.write(arr, 2); fout_lossy.write(arr, 2); Concealer.Receive((int16_t *)arr, 1); } } fin.close(); fout_repaired.close(); fout_lossy.close(); return 0; } PcmConcealer.hpp /* * Code adapted from Steve Underwood of the Asterisk Project. This code inherits * the same licensing restrictions as the Asterisk Project. */ #ifndef __PCMCONCEALER_HPP__ #define __PCMCONCEALER_HPP__ /** 1. What does it do? The packet loss concealment module provides a suitable synthetic fill-in signal, to minimise the audible effect of lost packets in VoIP applications. It is not tied to any particular codec, and could be used with almost any codec which does not specify its own procedure for packet loss concealment. Where a codec specific concealment procedure exists, the algorithm is usually built around knowledge of the characteristics of the particular codec. It will, therefore, generally give better results for that particular codec than this generic concealer will. 2. How does it work? While good packets are being received, the plc_rx() routine keeps a record of the trailing section of the known speech signal. If a packet is missed, plc_fillin() is called to produce a synthetic replacement for the real speech signal. The average mean difference function (AMDF) is applied to the last known good signal, to determine its effective pitch. Based on this, the last pitch period of signal is saved. Essentially, this cycle of speech will be repeated over and over until the real speech resumes. However, several refinements are needed to obtain smooth pleasant sounding results. - The two ends of the stored cycle of speech will not always fit together smoothly. This can cause roughness, or even clicks, at the joins between cycles. To soften this, the 1/4 pitch period of real speech preceeding the cycle to be repeated is blended with the last 1/4 pitch period of the cycle to be repeated, using an overlap-add (OLA) technique (i.e. in total, the last 5/4 pitch periods of real speech are used). - The start of the synthetic speech will not always fit together smoothly with the tail of real speech passed on before the erasure was identified. Ideally, we would like to modify the last 1/4 pitch period of the real speech, to blend it into the synthetic speech. However, it is too late for that. We could have delayed the real speech a little, but that would require more buffer manipulation, and hurt the efficiency of the no-lost-packets case (which we hope is the dominant case). Instead we use a degenerate form of OLA to modify the start of the synthetic data. The last 1/4 pitch period of real speech is time reversed, and OLA is used to blend it with the first 1/4 pitch period of synthetic speech. The result seems quite acceptable. - As we progress into the erasure, the chances of the synthetic signal being anything like correct steadily fall. Therefore, the volume of the synthesized signal is made to decay linearly, such that after 50ms of missing audio it is reduced to silence. - When real speech resumes, an extra 1/4 pitch period of sythetic speech is blended with the start of the real speech. If the erasure is small, this smoothes the transition. If the erasure is long, and the synthetic signal has faded to zero, the blending softens the start up of the real signal, avoiding a kind of "click" or "pop" effect that might occur with a sudden onset. 3. How do I use it? Before audio is processed, call plc_init() to create an instance of the packet loss concealer. For each received audio packet that is acceptable (i.e. not including those being dropped for being too late) call plc_rx() to record the content of the packet. Note this may modify the packet a little after a period of packet loss, to blend real synthetic data smoothly. When a real packet is not available in time, call plc_fillin() to create a sythetic substitute. That's it! */ /*!

• JSON, Ajax login and signup form problem, critique

  - by user552828

  Here is my problem; indexdeneme2.php has two forms Sign up and Login form, and there is validation.js and login.js which are handling the AJAX and JSON response, there are validate.php and login.php which are my scripts for validating and login. When you sign up, it sends the data to validate.php perfectly and validate.php response with JSON perfectly, validate.js must show the error in #error div. validation.js works perfectly if it is working alone. I use same kind of script for login form. Login.php also works perfectly it responses with JSON and login.js shows the errors are appear in #errorlogin div. But this works when login.js works alone. When I try to work login.js and validate.js together, it is not working. validate.php and login.php works perfectly but login.js and validation.js are not working together. They can't handle the responses coming from php scripts. It is not showing the errors in #errorlogin and #error div. They intercept each other I guess. By the way if you can critique my login.php and validate.php I will be really appreciated. Thank you all. this is indexdeneme2.php <?php include('functions.php')?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html;

• Content Box is a Little Off in IE9 ... How to Fix?

  - by Kelsey Nealon

  Hi there! I have a website at www.thetotempole.ca and when viewed in IE9... My websites content box (The green wooden backgrounded box with content inside) is moved slightly over to the left making a space between the actual container and the content box... Is there anyway I can fix this without harming any of the other browsers? Thanks!

On March 28, 2012, actor Will Ferrell officially announced the sequel dressed in character as Ron Burgundy on the late-night talk-show <em>Conan</em>. As with the original film, it is directed by Adam McKay, produced by Judd Apatow, stars Will Ferrell and is written by Adam McKay and Will Ferrell. Unlike the original film, which was distributed by DreamWorks Pictures, <em>The Legend Continues</em> will be distributed by Paramount Pictures.</p> <p align="left"><em><strong>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</strong></em>The movie now has a website at <a href="www.anchormanmovie.com">www.anchormanmovie.com</a> where a countdown for the release of this film can be seen. By the looks of these images, I think we can expect big things when the movie comes out this December.
