  • how to bind the same vector multiple times using R?

    - by hendrik
    question: how can i bind the same vector, lets say o=c(1,2,3,4) mutiple times to get a matrix like o=array(c(1,2,3,4,1,2,3,4,1,2,3,4), dim(c(4,3)) o [,1] [,2] [,3] [1,] 1 1 1 [2,] 2 2 2 [3,] 3 3 3 [4,] 4 4 4 in a nicer way then: o=cbind(o,o,o) and maybe more generalized (dublicate()?? I need this to specifiy colors for elements in textplot() thx a lot

  • Routing to a different URLs based on post type

    - by DanCake
    What would be the best way to set up my routes so different types of posts have different URLs? For example, regular posts are /posts/slug while featured posts are /featured/slug Both link to the same controller and action /posts/view/slug. I experimented with different ways of doing this but with little success. Currently my link params look something like the following: array('controller' => 'posts', 'action' => 'view', 'featured' ,$post['Post']['slug'])

  • JQuery.ajax(): Problem with parameter data when consuming a WCF Service

    - by Torben H.
    Hello, I'm using JQuery to consume a WCF Service. Actually this works fine: var para = ' { "Parameter" : { "ID" : "5", "Name" : "Peter" } }' $.ajax({ type: "POST", contentType: "application/json", data: para, url: url success: success }); But I don't want to pass the data parameter as String and I think it should be possible to pass ist as array in any way. Like that: var para = { "Parameter" : { "ID" : 5, "Name" : "Peter" } } But when I try this I'm getting an error. What I'm doing wrong? Thanks

  • What's a good jQuery ligthbox plugin that cycles through images? (like a carousel)

    - by Greg
    I'm looking for a jQuery lightbox plugin that has the ability to, with it's next and previous buttons, cycle through images repeatedly. Like a carousel effect. I've been using jQuery Lightbox Plugin (balupton edition) but that doesn't have the option to continue cycling through images. It reaches the last image in the array and then disables the 'next' button. So to save me some time coding, what are some plugins you can recommend?

  • Atmospheric scattering OpenGL 3.3

    - by user1419305
    Im currently trying to convert a shader by Sean O'Neil to version 330 so i can try it out in a application im writing. Im having some issues with deprecated functions, so i replaced them, but im almost completely new to glsl, so i probably did a mistake somewhere. Original shaders can be found here: http://www.gamedev.net/topic/592043-solved-trying-to-use-atmospheric-scattering-oneill-2004-but-get-black-sphere/ My horrible attempt at converting them: Vertex Shader: #version 330 core layout(location = 0) in vec3 vertexPosition_modelspace; //layout(location = 1) in vec2 vertexUV; layout(location = 2) in vec3 vertexNormal_modelspace; uniform vec3 v3CameraPos; uniform vec3 v3LightPos; uniform vec3 v3InvWavelength; uniform float fCameraHeight; uniform float fCameraHeight2; uniform float fOuterRadius; uniform float fOuterRadius2; uniform float fInnerRadius; uniform float fInnerRadius2; uniform float fKrESun; uniform float fKmESun; uniform float fKr4PI; uniform float fKm4PI; uniform float fScale; uniform float fScaleDepth; uniform float fScaleOverScaleDepth; // passing in matrixes for transformations uniform mat4 MVP; uniform mat4 V; uniform mat4 M; const int nSamples = 4; const float fSamples = 4.0; out vec3 v3Direction; out vec4 gg_FrontColor; out vec4 gg_FrontSecondaryColor; float scale(float fCos) { float x = 1.0 - fCos; return fScaleDepth * exp(-0.00287 + x*(0.459 + x*(3.83 + x*(-6.80 + x*5.25)))); } void main(void) { vec3 v3Pos = vertexPosition_modelspace; vec3 v3Ray = v3Pos - v3CameraPos; float fFar = length(v3Ray); v3Ray /= fFar; vec3 v3Start = v3CameraPos; float fHeight = length(v3Start); float fDepth = exp(fScaleOverScaleDepth * (fInnerRadius - fCameraHeight)); float fStartAngle = dot(v3Ray, v3Start) / fHeight; float fStartOffset = fDepth*scale(fStartAngle); float fSampleLength = fFar / fSamples; float fScaledLength = fSampleLength * fScale; vec3 v3SampleRay = v3Ray * fSampleLength; vec3 v3SamplePoint = v3Start + v3SampleRay * 0.5; vec3 v3FrontColor = vec3(0.0, 0.0, 0.0); for(int i=0; i<nSamples; i++) { float fHeight = length(v3SamplePoint); float fDepth = exp(fScaleOverScaleDepth * (fInnerRadius - fHeight)); float fLightAngle = dot(v3LightPos, v3SamplePoint) / fHeight; float fCameraAngle = dot(v3Ray, v3SamplePoint) / fHeight; float fScatter = (fStartOffset + fDepth*(scale(fLightAngle) - scale(fCameraAngle))); vec3 v3Attenuate = exp(-fScatter * (v3InvWavelength * fKr4PI + fKm4PI)); v3FrontColor += v3Attenuate * (fDepth * fScaledLength); v3SamplePoint += v3SampleRay; } gg_FrontSecondaryColor.rgb = v3FrontColor * fKmESun; gg_FrontColor.rgb = v3FrontColor * (v3InvWavelength * fKrESun); gl_Position = MVP * vec4(vertexPosition_modelspace,1); v3Direction = v3CameraPos - v3Pos; } Fragment Shader: #version 330 core uniform vec3 v3LightPos; uniform float g; uniform float g2; in vec3 v3Direction; out vec4 FragColor; in vec4 gg_FrontColor; in vec4 gg_FrontSecondaryColor; void main (void) { float fCos = dot(v3LightPos, v3Direction) / length(v3Direction); float fMiePhase = 1.5 * ((1.0 - g2) / (2.0 + g2)) * (1.0 + fCos*fCos) / pow(1.0 + g2 - 2.0*g*fCos, 1.5); FragColor = gg_FrontColor + fMiePhase * gg_FrontSecondaryColor; FragColor.a = FragColor.b; } I wrote a function to render a sphere, and im trying to render this shader onto a inverted version of it, the sphere works completely fine, with normals and all.

  • iPhone SDK: Track users location using GPS

    - by Nic Hubbard
    I have a few questions about CoreLocation and GPS. First, what method in core location is used to continually get the users current coordinates? And at what interval should these be retrieved? Second, should these coordinates be pushed into a NSMutableArray each time they are received, so that the array of coordinates will represent the users path? Thanks, just wanting to get started getting me mind around this.

  • How to checking wether an object has a specific method or not

    - by Ghommey
    Hey, I want to use a method of an object. Like $myObject->helloWorld(). However there are a couple of methods so I loop through an array of method names and call the method like this: my $methodName ="helloWorld"; $myObject->$methodNames; This works quite nice but some objects don't have all methods. How can I tell wether $myObject has a method called helloWorld or not?

  • Sort string based upon the count of characters Options

    - by prp
    Sample Data : input : "abcdacdc" Output : "cadb" here we have to sort strings in order of count of characters. If the count is same for characters. maintain the original order of the characters from input string. my approach: i have used array of 26 for maintaining occurrence of all characters and sort it then print it.But while doing so i am not able to maintain order in case if two characters have same count. please suggest any improvement or any other algo.

  • Flex, continuous scanning stream (from socket). Did I miss something using yywrap()?

    - by Diederich Kroeske
    Working on a socketbased scanner (continuous stream) using Flex for pattern recognition. Flex doesn't find a match that overlaps 'array bounderies'. So I implemented yywrap() to setup new array content as soon yylex() detects < (it will call yywrap). No success so far. Basically (for pin-pointing my problem) this is my code: %{ #include <stdio.h> #include <string.h> #include <stdlib.h> #define BUFFERSIZE 26 /* 0123456789012345678901234 */ char cbuf1[BUFFERSIZE] = "Hello everybody, lex is su"; // Warning, no '\0' char cbuf2[BUFFERSIZE] = "per cool. Thanks! "; char recvBuffer[BUFFERSIZE]; int packetCnt = 0; YY_BUFFER_STATE bufferState1, bufferState2; %} %option nounput %option noinput %% "super" { ECHO; } . { printf( "%c", yytext[0] );} %% int yywrap() { int retval = 1; printf(">> yywrap()\n"); if( packetCnt <= 0 ) // Stop after 2 { // Copy cbuf2 into recvBuffer memcpy(recvBuffer, cbuf2, BUFFERSIZE); // yyrestart(NULL); // ?? has no effect // Feed new data to flex bufferState2 = yy_scan_bytes(recvBuffer, BUFFERSIZE); // packetCnt++; // Tell flex to resume scanning retval = 0; } return(retval); } int main(void) { printf("Lenght: %d\n", (int)sizeof(recvBuffer)) ; // Copy cbuf1 into recvBuffer memcpy(recvBuffer, cbuf1, BUFFERSIZE); // packetCnt = 0; // bufferState1 = yy_scan_bytes(recvBuffer, BUFFERSIZE); // yylex(); yy_delete_buffer(bufferState1); yy_delete_buffer(bufferState2); return 0; } This is my output: dkmbpro:test dkroeske$ ./text Lenght: 26 Hello everybody, lex is su>> yywrap() per cool. Thanks! >> yywrap() So no match on 'super'. According to the doc the lexxer is not 'reset' between yywrap's. What do I miss? Thanks.

  • Problem with character encoding on email sent via PHP?

    - by cosgrove
    Hi everybody, Having some trouble sending properly formatted HTML e-mail from a PHP script. I am running PHP 5.3.0 and Apache 2.2.11 on Windows XP Professional. The output looks like this: Agent Summary for Support on Tuesday April 20 2010=20 Ext. Name Time Volume 137 Agent Name 01:27:25 1 138 =09 00:00:00 0 139 =09 00:00:00 0 You see the =20 and =09 in there? If you look at the HTML you also see = signs being turned into =3D. I figure this is a character encoding issue as I read the following at Wikipedia: ISO-8859-1 and Windows-1252 confusion It is very common to mislabel text data with the charset label ISO-8859-1, even though the data is really Windows-1252 encoded. In Windows-1252, codes between 0x80 and 0x9F are used for letters and punctuation, whereas they are control codes in ISO-8859-1. Many web browsers and e-mail clients will interpret ISO-8859-1 control codes as Windows-1252 characters in order to accommodate such mislabeling but it is not standard behaviour and care should be taken to avoid generating these characters in ISO-8859-1 labeled content. This looks like the problem but I don't know how to fix. My code looks like this: ob_start(); report_queue_summary($yesterday,$yesterday,$first_extension,$last_extension,$queue); $body_report = ob_get_contents(); ob_end_clean(); $body_footer = "This is an automatically generated e-mail."; $message = new Mail_mime(); $html = $body_header.$body_report.$body_footer; $message->setHTMLBody($html); $body = $message->get(); $extraheaders = array("From"=>"***redacted***","To"=>$recipient, "Subject"=>"Agent Summary for $yesterday [$queue]", "Content-type"=>"text/html; charset=iso-8859-1"); $headers = $message->headers($extraheaders); # setup e-mail; $host = "*********"; $port = "26"; $username = "*****"; $password = "*****"; # Send e-mail $smtp = Mail::factory('smtp', array ('host' => $host, 'port' => $port, 'auth' => true, 'username' => $username, 'password' => $password)); $mail = $smtp->send($recipient, $extraheaders, $body); if (PEAR::isError($mail)) { echo("" . $mail->getMessage() . ""); } else { echo("Message successfully sent!"); } Is the problem that I'm using output buffering?

    I'm implementing an MD-5 Hashing algorithm and I want to convert the text I have to bits so I can start manipulating them. As you know Hashing require taking block of bits and then manipulating them. There are many ways to do that but I can't determine the best/easiest way to just convert the text (string) into array of bits. Any clue ? In C#
