  • View controller is drawing under my navigation bar after popping ttthumbsviewcontroller

    - by scootklein
    I'm implementing the TTThumbsViewController from the Three20 project and things are finally starting to take shape. I push the TTThumbsViewController from the current view controller by just pushing it onto the current stack and animate the transition (common navigation controller push). My problem is that when I pop the TThumbsViewController view controller, the navigation controller is stuck in a mode where its view controllers are drawn UNDER the navigation bar (which is now translucent). Start Push Pop

  • Best tools for creating website wireframes

    - by Alison
    When creating a wireframe for a website, I always start with a Visio wireframe stencil from Garrett Dimon. The stencil is amazing but it has been a few years since it has been updated and I'm looking for something new and exciting. What wireframing tool(s) do you use, if any?

  • NoSQL is not about object databases

    - by Bertrand Le Roy
    NoSQL as a movement is an interesting beast. I kinda like that it’s negatively defined (I happen to belong myself to at least one other such a-community). It’s not in its roots about proposing one specific new silver bullet to kill an old problem. it’s about challenging the consensus. Actually, blindly and systematically replacing relational databases with object databases would just replace one set of issues with another. No, the point is to recognize that relational databases are not a universal answer -although they have been used as one for so long- and recognize instead that there’s a whole spectrum of data storage solutions out there. Why is it so hard to recognize, by the way? You are already using some of those other data storage solutions every day. Let me cite a few: The file system Active Directory XML / JSON documents The Web e-mail Logs Excel files EXIF blobs in your photos Relational databases And yes, object databases It’s just a fact of modern life. Notice by the way that most of the data that you use every day is unstructured and thus mostly unsuitable for relational storage. It really is more a matter of recognizing it: you are already doing NoSQL. So what happens when for any reason you need to simultaneously query two or more of these heterogeneous data stores? Well, you build an index of sorts combining them, and that’s what you query instead. Of course, there’s not much distance to travel from that to realizing that querying is better done when completely separated from storage. So why am I writing about this today? Well, that’s something I’ve been giving lots of thought, on and off, over the last ten years. When I built my first CMS all that time ago, one of the main problems my customers were facing was to manage and make sense of the mountain of unstructured data that was constituting most of their business. The central entity of that system was the file system because we were dealing with lots of Word documents, PDFs, OCR’d articles, photos and static web pages. We could have stored all that in SQL Server. It would have worked. Ew. I’m so glad we didn’t. Today, I’m working on Orchard (another CMS ;). It’s a pretty young project but already one of the questions we get the most is how to integrate existing data. One of the ideas I’ll be trying hard to sell to the rest of the team in the next few months is to completely split the querying from the storage. Not only does this provide great opportunities for performance optimizations, it gives you homogeneous access to heterogeneous and existing data sources. For free.

  • Help transferring Mac OS X fonts to Windows

    - by Addsy
    I have been sent a QuarkXPress document which contains a number of unusual fonts which were also sent to me. The fonts were in a folder named fonts and then it was all zipped up into a single archive containing the document and fonts folder. I believe this was done on a machine running Mac OS X. I have unzipped the archive, but all of the files in the fonts folder have no size - i.e. they are 0 bytes files. However there is also a _MACOSX folder which has a fonts subfolder. In here I can see all the font files (prefixed with .) and they all have a size, i.e. are not 0 bytes. Presumably these are the actual font files I need but I cannot figure out how to install them on Windows. I have tried renaming the files to have .ttf and .otf extensions and then installing them but that doesn't seem to work - I just get an "Invalid font file" message. Any other ideas?

  • Move rotating image along Canvas

    - by fatnic
    Hi. I've managed to make an image rotate on my canvas. And I've managed to make an image move along the canvas. My problem now is making it do both. I have got it working but I seems a bit like a hack. I've posted a demo online Here's the code. var cnv = document.getElementById("drawing"); var c = cnv.getContext('2d'); var image = new Image(); image.src = 'images/spaceship.png'; var imgWidth = image.width; var imgHeight = image.height; var i=0; function animate() { c.clearRect(0,0,640,480); c.save(); c.translate(-(imgWidth/2)+i,200); c.rotate(i * Math.PI/180); c.translate(-(imgWidth/2),-(imgHeight/2)); c.drawImage(image, 0, 0); c.restore(); (i==640+imgWidth) ? i=0: i+=2; }; setInterval(animate, 1); I think my problem is I'm not understanding the translate() method properly. Is this the correct way to do it or am I competely way off?

  • Basic Ruby On Rails Linking Help

    - by dweebsonduty
    So I am beginning to work with Rails and I get some of the concepts but am stuck on an important one. Let's say I have customers which has many jobs and jobs which belongs to customers. How would I go about creating a new job for a customer? I can create a link that goes to customers/1/jobs/new and I can grab the customer ID but how do I tell it that I am creating a job for customer 1? I know this is the most basic of things but I just need a push in the right direction. This is my form so far: How do I get :customer_id to populate with the customer_id param? <h1>New job</h1> <% form_for(@job) do |f| %> <%= f.error_messages %> <p> <%= f.label :customer_id %><br /> <%= f.text_field :customer_id %> </p> <p> <%= f.label :manufacturer %><br /> <%= f.text_field :manufacturer %> </p> <p> <%= f.label :serial_number %><br /> <%= f.text_field :serial_number %> </p> <p> <%= f.label :problem %><br /> <%= f.text_area :problem %> </p> <p> <%= f.label :notes %><br /> <%= f.text_area :notes %> </p> <p> <%= f.label :status %><br /> <%= f.text_field :status %> </p> <p> <%= f.label :tech_id %><br /> <%= f.text_field :tech_id %> </p> <p> <%= f.submit 'Create' %> </p> <% end %> <%= link_to 'Back', jobs_path %>

  • Javascript hide/show classes with checkbox

    - by Christina
    I am just learning javascript, so please bear with me! I want to be able to use checkboxes to choose to hide/show div classes (to basically filter the amount of info being shown). It is done in this... but I'm try to figure out something much simpler (since I don't need to dynamically generate the checkbox options.) I came across this example: The Javascript: function showMe (it, box) { var vis = (box.checked) ? "block" : "none"; document.getElementById(it).style.display = vis; } The HTML <form> <input type="checkbox" checked="checked" value="value1" onclick="showMe('div1', this)" />value1 <input type="checkbox" checked="checked" value="value2" onclick="showMe('div2', this)" />value2 <input type="checkbox" checked="checked" value="value3" onclick="showMe('div3', this)" />value3 </form> <div id="div1" style="display:block">Show Div 1</div> <div id="div2" style="display:block">Show Div 2</div> <div id="div3" style="display:block">Show Div 3</div> </body> </html> But it only works for div ids, not classes. Any idea on how I can work this? Thanks in advance if you can help me out!

  • Restricting Edit and Delete

    - by phleet
    I want to be able to edit and delete resources myself, but not allow users of the application to do so. Is there an easy way of doing this in Rails? An incomplete solution would be just to remove the "delete" and "edit" buttons from the index view, but that doesn't disable their ability to do so via direct HTTP requests. Running Rails 2.2.2 and ruby 1.8.7

    - by c0mrade
    Hello everyone, I'm creating additional module to already multi-module maven project. And for this one I want everything to be like in other modules(meaning dependencies) just to test hello world, then I'll go do some more complex stuff. And it does print hello world as it should when deployed onto jboss server, but I get some strange error on console, had anyone had similar experience? and how can I fix it? Here it is : 15:48:35,789 ERROR [STDERR] log4j:ERROR A "org.jboss.logging.appender.FileAppender" object is not assignable to a "org.apache.log4j.Appender" variable. 15:48:35,789 ERROR [STDERR] log4j:ERROR The class "org.apache.log4j.Appender" was loaded by 15:48:35,790 ERROR [STDERR] log4j:ERROR [BaseClassLoader@9a8d9b{vfszip:/C:/jboss-5.1.0.GA/server/default/deploy/new-module-0.0.1-SNAPSHOT.war/}] whereas object of type 15:48:35,790 ERROR [STDERR] log4j:ERROR "org.jboss.logging.appender.FileAppender" was loaded by [org.jboss.bootstrap.NoAnnotationURLClassLoader@506411]. 15:48:35,790 ERROR [STDERR] log4j:ERROR Could not instantiate appender named "FILE".

  • How to use javascript-xpath

    - by Nirmal Patel
    I am using Selenium RC with IE 6 and XPath locators are terribly slow. So I am trying to see if javascript-xpath actually speeds up things. But could not find enough/clear documentation on how to use native x- path libraries. I am doing the following: protected void startSelenium (String testServer, String appName, String testInBrowser){ selenium = new DefaultSelenium("localhost", 4444, "*" +testInBrowser, testServer+ "/"+ appName + "/"); echo("selenium instance created:"+selenium.getClass()); selenium.start(); echo("selenium instance started..." + testServer + "/" + appName +"/"); selenium.runScript("lib/javascript-xpath-latest-cmp.js"); selenium.useXpathLibrary("javascript-xpath"); selenium.allowNativeXpath("true"); } This results in speed improvement of XPath locator but the improvements are not consistent. On some runs the time taken for a locator is halved; while sometimes its randomly high. Am I missing any configuration step here? Would be great if someone who has had success with this could share their views and approach. Thanks, Nirmal

  • How to run a recorded (HTML) selenium test from .NET

    - by Gaspar Nagy
    I run Selenium tests with Selenium RC from .NET (c#). In some cases, I would like to keep the test case source as HTML (to be able to modify it from Selenium IDE), but I would like to run/include these tests from my c# unit tests. Maybe it is obvious, but I can't find the API method in the Selenium Core to achieve this. Any idea how to do that? (I think the "includePartial" command in Selenium on Rails does the thing that I would need, but for c#.)

  • How to resize a silverlight control to a full webpage.

    - by ForeverDebugging
    I'm currently using a datagrid within a user control. The datagrid resizes based on the number of rows, and therefore goes off the webpage. I've tried wrapping the control around a ScrollViewer, but in order to have the scroll bar visible and working, I need to set the MaxHeight of the datagrid. The problem is that I don't know what the MaxHeight of the datagrid should be because it differs based on the size of the browser window appearing on the screen. Any suggestions on how to determine the correct size of the control?
