  • Rails Controller Tests for Captcha using Shoulda, Factory Girl, Mocha

    - by Siva
    Can someone provide a strategy/code samples/pointers to test Captcha validations + Authlogic using Shoulda, Factory Girl and Mocha? For instance, my UsersController is something like: class UsersController < ApplicationController validates_captcha ... def create ... if captcha_validated? # code to deal with user attributes end ... end In this case, how do you mock/stub using Shoulda / Factory Girl / Mocha to test valid and invalid responses to the Captcha image? Appreciate your help, Siva

  • Compiling Gearman extension for PHP on OS-X Snow Leopard with Zend Server Community Edition

    - by GrumpyCanuck
    I was wondering if anyone else has figured out how to solve this problem. Whether I install the extension via PECL or compile it by hand, I get the same error: PHP Warning: PHP Startup: Unable to load dynamic library '/usr/local/zend/lib/php_extensions/gearman.so' - dlopen(/usr/local/zend/lib/php_extensions/gearman.so, 9): no suitable image found. Did find: /usr/local/zend/lib/php_extensions/gearman.so: mach-o, but wrong architecture in Unknown on line 0 I have no idea how to fix this problem and I can only bang my head into my desk so many times.

  • Detecting iPhone camera orientation

    - by Stephen Petschulat
    I'm getting inconsistent results depending on whether I get the image directly from the camera in the callback or choosing it from the camera roll. In the UIImagePickerControllerDelegate callback method, the UIImage.imageOrientation comes up as UIImageOrientationRight no matter how the photo is taken. When reading it off the Camera Roll, a landscape shot (turned left) comes up UIImageOrientationUp while a portrait shot comes up UIImageOrientationRight. How can I reliably get the camera orientation in both situations?

  • How do you send a HEAD HTTP request in Python?

    - by fuentesjr
    So what I'm trying to do here is get the headers of a given URL so I can determine the mime-type. I want to be able to see if http://somedomain/foo/ will return an html document or a jpg image for example. Thus, I need to figure out how to send a HEAD request so that I can read the mime-type without having to download the content. Does anyone know of an easy way of doing this?

  • JavaCC: Please help me understand token ambiguity.

    - by java.is.for.desktop
    Hello, everyone! I had already many problems with understanding, how ambiguous tokens can be handled elegantly (or somehow at all) in JavaCC. Let's take this example: I want to parse XML processing instruction. The format is: "<?" <target> <data> "?>": target is an XML name, data can be anything except ?>, because it's the closing tag. So, lets define this in JavaCC: (I use lexical states, in this case DEFAULT and PROC_INST) TOKEN : <#NAME : (very-long-definition-from-xml-1.1-goes-here) > TOKEN : <WSS : (" " | "\t")+ > // WSS = whitespaces <DEFAULT> TOKEN : {<PI_START : "<?" > : PROC_INST} <PROC_INST> TOKEN : {<PI_TARGET : <NAME> >} <PROC_INST> TOKEN : {<PI_DATA : ~[] >} // accept everything <PROC_INST> TOKEN : {<PI_END : "?>" > : DEFAULT} Now the part which recognizes processing instructions: void PROC_INSTR() : {} { ( <PI_START> (t=<PI_TARGET>){System.out.println("target: " + t.image);} <WSS> (t=<PI_DATA>){System.out.println("data: " + t.image);} <PI_END> ) {} } The problem is (i guess): hence <PI_DATA> recognizes "everything", my definition is wrong. Let's test it with <?mytarget here-goes-some-data?>: The target is recognized: "target: mytarget". But now I get my favorite JavaCC parsing error: !! procinstparser.ParseException: Encountered "" at line 1, column 15. !! Was expecting one of: !! Encountered nothing? Was expecting nothing? Or what? Thank you, JavaCC! I know, that I could use the MORE keyword of JavaCC, but this would give me the whole processing instruction as one token, so I'd had to parse/tokenize it further by myself. Why should I do that? Am I writing a parser that does not parse? What I would need is telling JavaCC to recognize "everything until ?>" as processing instruction data. How can it be done? Thank you.

  • Detect if visitor is on index page with client side scripting

    - by sterling
    Is it possible to detect if a visitor is on the index page or domain root with client side scripting? I figure javascript would be the best method as I would like to append a value to an image file based on wether a visitor is on the home page or not. Non-index page: <img src="/img/logo.png" /> Index page: <img src="/img/logo-home.png" />

  • Pick video using PhotoPickerPlus?

    - by Anil Katti
    Is there a way I can pick video using photo-picker-plus instead of a photo? When I check the media type using: NSString *mediaType = [info objectForKey: UIImagePickerControllerMediaType]; I always get public.image (even when I pick a video). On a related note, is there any other SDK similar to photo-picker-plus for picking video from different sources? UIImagePickerController could be an option. But, I am looking for something that is as versatile as photo-picker-plus. Anil

  • How can I fill a rect with an alpha color using CoreGraphics?

    - by Rits Plasman
    In my drawRect method, I am drawing a PNG image. On top of that, I want to draw a rect with a 20% alpha color, like this: [[UIColor colorWithWhite:0.0 alpha:0.2] set]; UIRectFill(rect); The problem is, that the alpha property seems to get ignored. No alpha is applied at all, just a black rectangle is drawn. How can I fix this? Thanks in advance!

  • Algorithm for Text Wrapping Within a Shape

    - by devongovett
    I am looking for an algorithm to wrap text within a non-rectangular shape, preferably based on the Knuth and Plass algorithm. The hardest part of this is that the lines may have different heights due to differing font sizes in the text. The image below is an example of what the algorithm should be able to generate. Thanks for any help!

  • How can I obtain raw data from a CVImageBuffer object.

    - by jslap
    Hi, I'm trying to use cocoa to grab images from a webcam. I'm able to get the image in RGBA format using the QTKit and the didOutputVideoFrame delegate call, and converting the CVImageBuffer to a CIImage and then to a NSBitmapImageRep. I know my camera grabs natively in YUV, what I want is to get the YUV data directly from the CVImageBuffer, and proccess the YUV frame before displaying it. My question is: How can I get the YUV data from the CVImageBuffer? thanks.

  • Can immutable be a memory hog?

    - by ciscoheat
    Let's say we have a memory-intensive class like an Image, with chainable methods like Resize() and ConvertTo(). If this class is immutable, won't it take a huge amount of memory when I start doing things like i.Resize(500, 800).Rotate(90).ConvertTo(Gif), compared to a mutable one which modifies itself? How to handle a situation like this in a functional language?

  • My ASP.NET Accordion will not animate panel changes when triggered by check boxes.

    My accordion panel in markup: <ajaxToolkit:Accordion ID="MyAccordion" runat="server" SelectedIndex="0" HeaderCssClass="accordionHeader" HeaderSelectedCssClass="accordionHeaderSelected" ContentCssClass="accordionContent" AutoSize="None" FadeTransitions="true" TransitionDuration="250" FramesPerSecond="40" RequireOpenedPane="false" SuppressHeaderPostbacks="true"> <Panes> <ajaxToolkit:AccordionPane ID="AccordionPane10" runat="server"> <Header>BBBBBBBBBB</Header> <Content> FFFFFFFF:<br /><br /> <table cellpadding="0" cellspacing="0" width="750"><tr><td width="450" class="verificationtdleft"> <asp:Image ID="step4_originalimage" runat="server" AlternateText="" /> </td><td width="300"> <asp:CheckBox ID="CB_Verification0" runat="server" AutoPostBack="true" /> Verify </td></tr> </table> </Content> </ajaxToolkit:AccordionPane> <ajaxToolkit:AccordionPane ID="AccordionPane11" runat="server"> <Header>GGGGGGGGG</Header> <Content> HHHHHHHHHH:<br /><br /> <table cellpadding="0" cellspacing="0" width="750"><tr><td width="450" class="verificationtdleft"> <asp:Image ID="step4_image_thumbnail" runat="server" AlternateText="" /> </td><td width="300"> <asp:CheckBox ID="CB_Verification1" runat="server" AutoPostBack="true" /> Verify </td></tr> </table> </Content> </ajaxToolkit:AccordionPane> </Panes> Here's how I handle the checkbox check: Private Sub CB_Verification0_CheckedChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles CB_Verification0.CheckedChanged MyAccordion.SelectedIndex = 1 End Sub I'm causing the panels to change correctly, it's just that they don't animate like they do when I click the headers. When I click the checkbox to change the panel, the panel just disappears instantly and the new one appears instantly, but I want it to be animated as if I clicked the headers. Is there a way to cause the animation to happen when force changing the visible panel?
