  • Duplicate content issue after URL-change with 301-redirects

    - by David
    We got the following problem: We changed all URLs on our page from oldURL.html to newURL.html and set up 301-redirects (ca. 600 URLs) Google re-crawled our page, indexed all the new URLs (newURL.html), but didn't crawl the old URLs (oldURL.html) again, as there were no internal links pointing at those domains anymore after the URL-change. This resulted in massive ranking-drops, etc. because (i) Google thought oldURL.html has exactly the same content as newURL, causing duplicate content issues, and (ii) Google did not transfer the juice from oldURL to newURL, because the 301-redirect was never noticed. Now we reset all internal Links to the old URLs again, which then redirect to the newURLs, in the hope that Google would re-crawl the pages, once there are internal links pointing at them. This is partially happening, but at a really low speed, so it would take multiple months to notice all-redirects. I guess, because Google thinks: "Aah, I already know oldURL.html, so no need to re-crawl it. Possible solutions we thought of are ... Submitting as many of the old URLs to the index as possible via Webmaster Tools, to manually trigger a crawl. Doing that already Submitting a sitemap with all old URLs - but not sure if good idea, because Google does not seem to like 301-redirects in a sitemap ... Both solutions are not perfect - and we cannot wait for three months, just to regain our old rankings. What are your ideas? Best, David

  • OpenGL and atlas

    - by user30088
    I'm trying to draw element from a texture atlas with OpenGL ES 2. Currently, I'm drawing my elements using something like that in the shader: uniform mat4 uCamera; uniform mat4 uModel; attribute vec4 aPosition; attribute vec4 aColor; attribute vec2 aTextCoord; uniform vec2 offset; uniform vec2 scale; varying lowp vec4 vColor; varying lowp vec2 vUV; void main() { vUV = offset + aTextCoord * scale; gl_Position = (uCamera * uModel) * aPosition; vColor = aColor; } For each elements to draw I send his offset and scale to the shader. The problem with this method: I can't rotate the element but it's not a problem for now. I would like to know, what is better for performance: Send uniforms like that for each element on every frames Update quad geometry (uvs) for each element Thanks!

  • Detecting HTML5/CSS3 Features using Modernizr

    - by dwahlin
    HTML5, CSS3, and related technologies such as canvas and web sockets bring a lot of useful new features to the table that can take Web applications to the next level. These new technologies allow applications to be built using only HTML, CSS, and JavaScript allowing them to be viewed on a variety of form factors including tablets and phones. Although HTML5 features offer a lot of promise, it’s not realistic to develop applications using the latest technologies without worrying about supporting older browsers in the process. If history has taught us anything it’s that old browsers stick around for years and years which means developers have to deal with backward compatibility issues. This is especially true when deploying applications to the Internet that target the general public. This begs the question, “How do you move forward with HTML5 and CSS3 technologies while gracefully handling unsupported features in older browsers?” Although you can write code by hand to detect different HTML5 and CSS3 features, it’s not always straightforward. For example, to check for canvas support you need to write code similar to the following:   <script> window.onload = function () { if (canvasSupported()) { alert('canvas supported'); } }; function canvasSupported() { var canvas = document.createElement('canvas'); return (canvas.getContext && canvas.getContext('2d')); } </script> If you want to check for local storage support the following check can be made. It’s more involved than it should be due to a bug in older versions of Firefox. <script> window.onload = function () { if (localStorageSupported()) { alert('local storage supported'); } }; function localStorageSupported() { try { return ('localStorage' in window && window['localStorage'] != null); } catch(e) {} return false; } </script> Looking through the previous examples you can see that there’s more than meets the eye when it comes to checking browsers for HTML5 and CSS3 features. It takes a lot of work to test every possible scenario and every version of a given browser. Fortunately, you don’t have to resort to writing custom code to test what HTML5/CSS3 features a given browser supports. By using a script library called Modernizr you can add checks for different HTML5/CSS3 features into your pages with a minimal amount of code on your part. Let’s take a look at some of the key features Modernizr offers.   Getting Started with Modernizr The first time I heard the name “Modernizr” I thought it “modernized” older browsers by added missing functionality. In reality, Modernizr doesn’t actually handle adding missing features or “modernizing” older browsers. The Modernizr website states, “The name Modernizr actually stems from the goal of modernizing our development practices (and ourselves)”. Because it relies on feature detection rather than browser sniffing (a common technique used in the past – that never worked that great), Modernizr definitely provides a more modern way to test features that a browser supports and can even handle loading additional scripts called shims or polyfills that fill in holes that older browsers may have. It’s a great tool to have in your arsenal if you’re a web developer. Modernizr is available at http://modernizr.com. Two different types of scripts are available including a development script and custom production script. To generate a production script, the site provides a custom script generation tool rather than providing a single script that has everything under the sun for HTML5/CSS3 feature detection. Using the script generation tool you can pick the specific test functionality that you need and ignore everything that you don’t need. That way the script is kept as small as possible. An example of the custom script download screen is shown next. Notice that specific CSS3, HTML5, and related feature tests can be selected. Once you’ve downloaded your custom script you can add it into your web page using the standard <script> element and you’re ready to start using Modernizr. <script src="Scripts/Modernizr.js" type="text/javascript"></script>   Modernizr and the HTML Element Once you’ve add a script reference to Modernizr in a page it’ll go to work for you immediately. In fact, by adding the script several different CSS classes will be added to the page’s <html> element at runtime. These classes define what features the browser supports and what features it doesn’t support. Features that aren’t supported get a class name of “no-FeatureName”, for example “no-flexbox”. Features that are supported get a CSS class name based on the feature such as “canvas” or “websockets”. An example of classes added when running a page in Chrome is shown next:   <html class=" js flexbox canvas canvastext webgl no-touch geolocation postmessage websqldatabase indexeddb hashchange history draganddrop websockets rgba hsla multiplebgs backgroundsize borderimage borderradius boxshadow textshadow opacity cssanimations csscolumns cssgradients cssreflections csstransforms csstransforms3d csstransitions fontface generatedcontent video audio localstorage sessionstorage webworkers applicationcache svg inlinesvg smil svgclippaths"> Here’s an example of what the <html> element looks like at runtime with Internet Explorer 9:   <html class=" js no-flexbox canvas canvastext no-webgl no-touch geolocation postmessage no-websqldatabase no-indexeddb hashchange no-history draganddrop no-websockets rgba hsla multiplebgs backgroundsize no-borderimage borderradius boxshadow no-textshadow opacity no-cssanimations no-csscolumns no-cssgradients no-cssreflections csstransforms no-csstransforms3d no-csstransitions fontface generatedcontent video audio localstorage sessionstorage no-webworkers no-applicationcache svg inlinesvg smil svgclippaths">   When using Modernizr it’s a common practice to define an <html> element in your page with a no-js class added as shown next:   <html class="no-js">   You’ll see starter projects such as HTML5 Boilerplate (http://html5boilerplate.com) or Initializr (http://initializr.com) follow this approach (see my previous post for more information on HTML5 Boilerplate). By adding the no-js class it’s easy to tell if a browser has JavaScript enabled or not. If JavaScript is disabled then no-js will stay on the <html> element. If JavaScript is enabled, no-js will be removed by Modernizr and a js class will be added along with other classes that define supported/unsupported features. Working with HTML5 and CSS3 Features You can use the CSS classes added to the <html> element directly in your CSS files to determine what style properties to use based upon the features supported by a given browser. For example, the following CSS can be used to render a box shadow for browsers that support that feature and a simple border for browsers that don’t support the feature: .boxshadow #MyContainer { border: none; -webkit-box-shadow: #666 1px 1px 1px; -moz-box-shadow: #666 1px 1px 1px; } .no-boxshadow #MyContainer { border: 2px solid black; }   If a browser supports box-shadows the boxshadow CSS class will be added to the <html> element by Modernizr. It can then be associated with a given element. This example associates the boxshadow class with a div with an id of MyContainer. If the browser doesn’t support box shadows then the no-boxshadow class will be added to the <html> element and it can be used to render a standard border around the div. This provides a great way to leverage new CSS3 features in supported browsers while providing a graceful fallback for older browsers. In addition to using the CSS classes that Modernizr provides on the <html> element, you also use a global Modernizr object that’s created. This object exposes different properties that can be used to detect the availability of specific HTML5 or CSS3 features. For example, the following code can be used to detect canvas and local storage support. You can see that the code is much simpler than the code shown at the beginning of this post. It also has the added benefit of being tested by a large community of web developers around the world running a variety of browsers.   $(document).ready(function () { if (Modernizr.canvas) { //Add canvas code } if (Modernizr.localstorage) { //Add local storage code } }); The global Modernizr object can also be used to test for the presence of CSS3 features. The following code shows how to test support for border-radius and CSS transforms:   $(document).ready(function () { if (Modernizr.borderradius) { $('#MyDiv').addClass('borderRadiusStyle'); } if (Modernizr.csstransforms) { $('#MyDiv').addClass('transformsStyle'); } });   Several other CSS3 feature tests can be performed such as support for opacity, rgba, text-shadow, CSS animations, CSS transitions, multiple backgrounds, and more. A complete list of supported HTML5 and CSS3 tests that Modernizr supports can be found at http://www.modernizr.com/docs.   Loading Scripts using Modernizr In cases where a browser doesn’t support a specific feature you can either provide a graceful fallback or load a shim/polyfill script to fill in missing functionality where appropriate (more information about shims/polyfills can be found at https://github.com/Modernizr/Modernizr/wiki/HTML5-Cross-Browser-Polyfills). Modernizr has a built-in script loader that can be used to test for a feature and then load a script if the feature isn’t available. The script loader is built-into Modernizr and is also available as a standalone yepnope script (http://yepnopejs.com). It’s extremely easy to get started using the script loader and it can really simplify the process of loading scripts based on the availability of a particular browser feature. To load scripts dynamically you can use Modernizr’s load() function which accepts properties defining the feature to test (test property), the script to load if the test succeeds (yep property), the script to load if the test fails (nope property), and a script to load regardless of if the test succeeds or fails (both property). An example of using load() with these properties is show next: Modernizr.load({ test: Modernizr.canvas, yep: 'html5CanvasAvailable.js’, nope: 'excanvas.js’, both: 'myCustomScript.js' }); In this example Modernizr is used to not only load scripts but also to test for the presence of the canvas feature. If the target browser supports the HTML5 canvas then the html5CanvasAvailable.js script will be loaded along with the myCustomScript.js script (use of the yep property in this example is a bit contrived – it was added simply to demonstrate how the property can be used in the load() function). Otherwise, a polyfill script named excanvas.js will be loaded to add missing canvas functionality for Internet Explorer versions prior to 9. Once excanvas.js is loaded the myCustomScript.js script will be loaded. Because Modernizr handles loading scripts, you can also use it in creative ways. For example, you can use it to load local scripts when a 3rd party Content Delivery Network (CDN) such as one provided by Google or Microsoft is unavailable for whatever reason. The Modernizr documentation provides the following example that demonstrates the process for providing a local fallback for jQuery when a CDN is down:   Modernizr.load([ { load: '//ajax.googleapis.com/ajax/libs/jquery/1.6.4/jquery.js', complete: function () { if (!window.jQuery) { Modernizr.load('js/libs/jquery-1.6.4.min.js'); } } }, { // This will wait for the fallback to load and // execute if it needs to. load: 'needs-jQuery.js' } ]); This code attempts to load jQuery from the Google CDN first. Once the script is downloaded (or if it fails) the function associated with complete will be called. The function checks to make sure that the jQuery object is available and if it’s not Modernizr is used to load a local jQuery script. After all of that occurs a script named needs-jQuery.js will be loaded. Conclusion If you’re building applications that use some of the latest and greatest features available in HTML5 and CSS3 then Modernizr is an essential tool. By using it you can reduce the amount of custom code required to test for browser features and provide graceful fallbacks or even load shim/polyfill scripts for older browsers to help fill in missing functionality.

  • Adjust spacing between list elements in Word 2010

    - by Steve
    Is there a way to adjust the spacing between list elements in Word 2010? I can apply a style to the list, and then edit the style, and edit the spacing before and after the element, but this applies to the list, not the list element. There are no styles I can see which can be applied to a list element allowing the spacing between list elements to be adjusted. If I select 1 list element, and then adjust the spacing before or after in the Page Layout tab, this applies to the whole list, not the list element, which defeats the purpose.

  • Is this form of cloaking likely to be penalised?

    - by Flo
    I'm looking to create a website which is considerably javascript heavy, built with backbone.js and most content being passed as JSON and loaded via backbone. I just needed some advice or opinions on likely hood of my website being penalised using the method of serving plain HTML (text, images, everything) to search engine bots and an js front-end version to normal users. This is my basic plan for my site: I plan on having the first request to any page being html which will only give about 1/4 of the page and there after load the last 3/4 with backbone js. Therefore non javascript users get a 'bit' of the experience. Once that new user has visited and detected to have js will have a cookie saved on their machine and requests from there after will be AJAX only. Example If (AJAX || HasJSCookie) { // Pass JSON } Search Engine server content: That entire experience of loading via AJAX will be stripped if a google bot for example is detected, the same content will be servered but all html. I thought about just allowing search engines to index the first 1/4 of content but as I'm considered about inner links and picking up every bit of content I thought it would be better to give search engines the entire content. I plan to do this by just detected a list of user agents and knowing if it's a bot or not. If (Bot) { //server plain html } In addition I plan to make clean URLs for the entire website despite full AJAX, therefore providing AJAX content to www.example.com/#/page and normal html to www.example.com/page is kind of our of the question. Would rather avoid the practice of using # when there are technology such as HTML 5 push state is around. So my question is really just asking the opinion of the masses on if it's likely that my website will be penalised? And do you suggest an alternative which avoids 'noscript' method

  • Creating a new naming context in OUD

    - by Sylvain Duloutre
    A naming context (also known as a directory suffix) is a DN that identifies the top entry in a locally held directory hierarchy. A new naming context can be created using ODSM, the OUD gui admin console, as described in http://docs.oracle.com/cd/E29407_01/admin.111200/e22648/server_config.htm#CBDGCJGF It can also be created using the dsconfig command lione as described below: Creation of a new naming context consists in 3 steps: First create a Local Backend Workflow element (myNewDb in this exemple) ,  responsible for the naming context base dn, e.g o=example. dsconfig create-workflow-element \           --set base-dn:o=example \           --set enabled:true \           --type db-local-backend \           --element-name myNewDb \           --hostname <your host> \           --port <admin port> \           --bindDN cn=Directory\ Manager \           --bindPasswordFile ****** \           --no-prompt Second, create a Workflow element (workFlowForMyNewDb in this exemple) associated with the Local Backend Workflow element. WorkFlow elements are used to route LDAP requests to the appropriate database, based on the target base dn. dsconfig create-workflow \           --set base-dn:o=example \           --set enabled:true \           --set workflow-element:myNewDb \           --type generic \           --workflow-name workFlowForMyNewDb \           --hostname <your host name> \           --port <admin port>\           --bindDN cn=Directory\ Manager \           --bindPasswordFile ****** \           --no-prompt Then, the workflow element must be made visible outside of the directory, i.e added to the internal "routing table". This is done by adding the Workflow to the appropriate Network Group. A Network group  is used to classify incoming client connections and route requests to workflows. dsconfig set-network-group-prop \           --group-name network-group \           --add workflow:workFlowForMyNewDb \           --hostname <your hostname> \           --port <admin port>\           --bindDN cn=Directory\ Manager \           --bindPasswordFile ****** \           --no-prompt At that stage, it is possible to import entries to the new naming context o=example.

    HTML5, CSS3, and related technologies such as canvas and web sockets bring a lot of useful new features to the table that can take Web applications to the next level. These new technologies allow applications to be built using only HTML, CSS, and JavaScript allowing them to be viewed on a variety of form factors including tablets and phones. Although HTML5 features offer a lot of promise, it’s not realistic to develop applications using the latest technologies without worrying about supporting older browsers in the process. If history has taught us anything it’s that old browsers stick around for years and years which means developers have to deal with backward compatibility issues. This is especially true when deploying applications to the Internet that target the general public. This begs the question, “How do you move forward with HTML5 and CSS3 technologies while gracefully handling unsupported features in older browsers?” Although you can write code by hand to detect different HTML5 and CSS3 features, it’s not always straightforward. For example, to check for canvas support you need to write code similar to the following:   <script> window.onload = function () { if (canvasSupported()) { alert('canvas supported'); } }; function canvasSupported() { var canvas = document.createElement('canvas'); return (canvas.getContext && canvas.getContext('2d')); } </script> If you want to check for local storage support the following check can be made. It’s more involved than it should be due to a bug in older versions of Firefox. <script> window.onload = function () { if (localStorageSupported()) { alert('local storage supported'); } }; function localStorageSupported() { try { return ('localStorage' in window && window['localStorage'] != null); } catch(e) {} return false; } </script> Looking through the previous examples you can see that there’s more than meets the eye when it comes to checking browsers for HTML5 and CSS3 features. It takes a lot of work to test every possible scenario and every version of a given browser. Fortunately, you don’t have to resort to writing custom code to test what HTML5/CSS3 features a given browser supports. By using a script library called Modernizr you can add checks for different HTML5/CSS3 features into your pages with a minimal amount of code on your part. Let’s take a look at some of the key features Modernizr offers.   Getting Started with Modernizr The first time I heard the name “Modernizr” I thought it “modernized” older browsers by added missing functionality. In reality, Modernizr doesn’t actually handle adding missing features or “modernizing” older browsers. The Modernizr website states, “The name Modernizr actually stems from the goal of modernizing our development practices (and ourselves)”. Because it relies on feature detection rather than browser sniffing (a common technique used in the past – that never worked that great), Modernizr definitely provides a more modern way to test features that a browser supports and can even handle loading additional scripts called shims or polyfills that fill in holes that older browsers may have. It’s a great tool to have in your arsenal if you’re a web developer. Modernizr is available at http://modernizr.com. Two different types of scripts are available including a development script and custom production script. To generate a production script, the site provides a custom script generation tool rather than providing a single script that has everything under the sun for HTML5/CSS3 feature detection. Using the script generation tool you can pick the specific test functionality that you need and ignore everything that you don’t need. That way the script is kept as small as possible. An example of the custom script download screen is shown next. Notice that specific CSS3, HTML5, and related feature tests can be selected. Once you’ve downloaded your custom script you can add it into your web page using the standard <script> element and you’re ready to start using Modernizr. <script src="Scripts/Modernizr.js" type="text/javascript"></script>   Modernizr and the HTML Element Once you’ve add a script reference to Modernizr in a page it’ll go to work for you immediately. In fact, by adding the script several different CSS classes will be added to the page’s <html> element at runtime. These classes define what features the browser supports and what features it doesn’t support. Features that aren’t supported get a class name of “no-FeatureName”, for example “no-flexbox”. Features that are supported get a CSS class name based on the feature such as “canvas” or “websockets”. An example of classes added when running a page in Chrome is shown next:   <html class=" js flexbox canvas canvastext webgl no-touch geolocation postmessage websqldatabase indexeddb hashchange history draganddrop websockets rgba hsla multiplebgs backgroundsize borderimage borderradius boxshadow textshadow opacity cssanimations csscolumns cssgradients cssreflections csstransforms csstransforms3d csstransitions fontface generatedcontent video audio localstorage sessionstorage webworkers applicationcache svg inlinesvg smil svgclippaths"> Here’s an example of what the <html> element looks like at runtime with Internet Explorer 9:   <html class=" js no-flexbox canvas canvastext no-webgl no-touch geolocation postmessage no-websqldatabase no-indexeddb hashchange no-history draganddrop no-websockets rgba hsla multiplebgs backgroundsize no-borderimage borderradius boxshadow no-textshadow opacity no-cssanimations no-csscolumns no-cssgradients no-cssreflections csstransforms no-csstransforms3d no-csstransitions fontface generatedcontent video audio localstorage sessionstorage no-webworkers no-applicationcache svg inlinesvg smil svgclippaths">   When using Modernizr it’s a common practice to define an <html> element in your page with a no-js class added as shown next:   <html class="no-js">   You’ll see starter projects such as HTML5 Boilerplate (http://html5boilerplate.com) or Initializr (http://initializr.com) follow this approach (see my previous post for more information on HTML5 Boilerplate). By adding the no-js class it’s easy to tell if a browser has JavaScript enabled or not. If JavaScript is disabled then no-js will stay on the <html> element. If JavaScript is enabled, no-js will be removed by Modernizr and a js class will be added along with other classes that define supported/unsupported features. Working with HTML5 and CSS3 Features You can use the CSS classes added to the <html> element directly in your CSS files to determine what style properties to use based upon the features supported by a given browser. For example, the following CSS can be used to render a box shadow for browsers that support that feature and a simple border for browsers that don’t support the feature: .boxshadow #MyContainer { border: none; -webkit-box-shadow: #666 1px 1px 1px; -moz-box-shadow: #666 1px 1px 1px; } .no-boxshadow #MyContainer { border: 2px solid black; }   If a browser supports box-shadows the boxshadow CSS class will be added to the <html> element by Modernizr. It can then be associated with a given element. This example associates the boxshadow class with a div with an id of MyContainer. If the browser doesn’t support box shadows then the no-boxshadow class will be added to the <html> element and it can be used to render a standard border around the div. This provides a great way to leverage new CSS3 features in supported browsers while providing a graceful fallback for older browsers. In addition to using the CSS classes that Modernizr provides on the <html> element, you also use a global Modernizr object that’s created. This object exposes different properties that can be used to detect the availability of specific HTML5 or CSS3 features. For example, the following code can be used to detect canvas and local storage support. You can see that the code is much simpler than the code shown at the beginning of this post. It also has the added benefit of being tested by a large community of web developers around the world running a variety of browsers.   $(document).ready(function () { if (Modernizr.canvas) { //Add canvas code } if (Modernizr.localstorage) { //Add local storage code } }); The global Modernizr object can also be used to test for the presence of CSS3 features. The following code shows how to test support for border-radius and CSS transforms:   $(document).ready(function () { if (Modernizr.borderradius) { $('#MyDiv').addClass('borderRadiusStyle'); } if (Modernizr.csstransforms) { $('#MyDiv').addClass('transformsStyle'); } });   Several other CSS3 feature tests can be performed such as support for opacity, rgba, text-shadow, CSS animations, CSS transitions, multiple backgrounds, and more. A complete list of supported HTML5 and CSS3 tests that Modernizr supports can be found at http://www.modernizr.com/docs.   Loading Scripts using Modernizr In cases where a browser doesn’t support a specific feature you can either provide a graceful fallback or load a shim/polyfill script to fill in missing functionality where appropriate (more information about shims/polyfills can be found at https://github.com/Modernizr/Modernizr/wiki/HTML5-Cross-Browser-Polyfills). Modernizr has a built-in script loader that can be used to test for a feature and then load a script if the feature isn’t available. The script loader is built-into Modernizr and is also available as a standalone yepnope script (http://yepnopejs.com). It’s extremely easy to get started using the script loader and it can really simplify the process of loading scripts based on the availability of a particular browser feature. To load scripts dynamically you can use Modernizr’s load() function which accepts properties defining the feature to test (test property), the script to load if the test succeeds (yep property), the script to load if the test fails (nope property), and a script to load regardless of if the test succeeds or fails (both property). An example of using load() with these properties is show next: Modernizr.load({ test: Modernizr.canvas, yep: 'html5CanvasAvailable.js’, nope: 'excanvas.js’, both: 'myCustomScript.js' }); In this example Modernizr is used to not only load scripts but also to test for the presence of the canvas feature. If the target browser supports the HTML5 canvas then the html5CanvasAvailable.js script will be loaded along with the myCustomScript.js script (use of the yep property in this example is a bit contrived – it was added simply to demonstrate how the property can be used in the load() function). Otherwise, a polyfill script named excanvas.js will be loaded to add missing canvas functionality for Internet Explorer versions prior to 9. Once excanvas.js is loaded the myCustomScript.js script will be loaded. Because Modernizr handles loading scripts, you can also use it in creative ways. For example, you can use it to load local scripts when a 3rd party Content Delivery Network (CDN) such as one provided by Google or Microsoft is unavailable for whatever reason. The Modernizr documentation provides the following example that demonstrates the process for providing a local fallback for jQuery when a CDN is down:   Modernizr.load([ { load: '//ajax.googleapis.com/ajax/libs/jquery/1.6.4/jquery.js', complete: function () { if (!window.jQuery) { Modernizr.load('js/libs/jquery-1.6.4.min.js'); } } }, { // This will wait for the fallback to load and // execute if it needs to. load: 'needs-jQuery.js' } ]); This code attempts to load jQuery from the Google CDN first. Once the script is downloaded (or if it fails) the function associated with complete will be called. The function checks to make sure that the jQuery object is available and if it’s not Modernizr is used to load a local jQuery script. After all of that occurs a script named needs-jQuery.js will be loaded. Conclusion If you’re building applications that use some of the latest and greatest features available in HTML5 and CSS3 then Modernizr is an essential tool. By using it you can reduce the amount of custom code required to test for browser features and provide graceful fallbacks or even load shim/polyfill scripts for older browsers to help fill in missing functionality.

  • Building on someone else's DefaultButton Silverlight work...

    - by KyleBurns
    This week I was handed a "simple" requirement - have a search screen execute its search when the user pressed the Enter key instead of having to move hands from keyboard to mouse and click Search.  That is a reasonable request that has been met for years both in Windows and Web apps.  I did a quick scan for code to pilfer and found Patrick Cauldwell's Blog posting "A 'Default Button' In Silverlight".  This posting was a great start and I'm glad that the basic work had been done for me, but I ran into one issue - when using bound textboxes (I'm a die-hard MVVM enthusiast when it comes to Silverlight development), the search was being executed before the textbox I was in when the Enter key was pressed updated its bindings.  With a little bit of reflection work, I think I have found a good generic solution that builds upon Patrick's to make it more binding-friendly.  Also, I wanted to set the DefaultButton at a higher level than on each TextBox (or other control for that matter), so the use of mine is intended to be set somewhere such as the LayoutRoot or other high level control and will apply to all controls beneath it in the control tree.  I haven't tested this on controls that treat the Enter key special themselves in the mix. The real change from Patrick's solution here is that in the KeyUp event, I grab the source of the KeyUp event (in my case the textbox containing search criteria) and loop through the static fields on the element's type looking for DependencyProperty instances.  When I find a DependencyProperty, I grab the value and query for bindings.  Each time I find a binding, UpdateSource is called to make sure anything bound to any property of the field has the opportunity to update before the action represented by the DefaultButton is executed. Here's the code: public class DefaultButtonService { public static DependencyProperty DefaultButtonProperty = DependencyProperty.RegisterAttached("DefaultButton", typeof (Button), typeof (DefaultButtonService), new PropertyMetadata (null, DefaultButtonChanged)); private static void DefaultButtonChanged(DependencyObject d, DependencyPropertyChangedEventArgs e) { var uiElement = d as UIElement; var button = e.NewValue as Button; if (uiElement != null && button != null) { uiElement.KeyUp += (sender, arg) => { if (arg.Key == Key.Enter) { var element = arg.OriginalSource as FrameworkElement; if (element != null) { UpdateBindings(element); } if (button.IsEnabled) { button.Focus(); var peer = new ButtonAutomationPeer(button); var invokeProv = peer.GetPattern(PatternInterface.Invoke) as IInvokeProvider; if (invokeProv != null) invokeProv.Invoke(); arg.Handled = true; } } }; } } public static DefaultButtonService GetDefaultButton(UIElement obj) { return (DefaultButtonService) obj.GetValue(DefaultButtonProperty); } public static void SetDefaultButton(DependencyObject obj, DefaultButtonService button) { obj.SetValue(DefaultButtonProperty, button); } public static void UpdateBindings(FrameworkElement element) { element.GetType().GetFields(BindingFlags.Public | BindingFlags.Static).ForEach(field => { if (field.FieldType.IsAssignableFrom(typeof(DependencyProperty))) { try { var dp = field.GetValue(null) as DependencyProperty; if (dp != null) { var binding = element.GetBindingExpression(dp); if (binding != null) { binding.UpdateSource(); } } } // ReSharper disable EmptyGeneralCatchClause catch (Exception) // ReSharper restore EmptyGeneralCatchClause { // swallow exceptions } } }); } }

  • CakePHP in a subdirectory using nginx (Rewrite rules?)

    - by lhnz
    I managed to get this to work a while back, but on returning to the cakephp project I had started it seems that whatever changes I've made to nginx recently (or perhaps a recent update) have broken my rewrite rules. Currently I have: worker_processes 1; events { worker_connections 1024; } http { include mime.types; default_type application/octet-stream; sendfile on; keepalive_timeout 65; server { listen 80; server_name localhost; location / { root html; index index.php index.html index.htm; } location /basic_cake/ { index index.php; if (-f $request_filename) { break; } if (!-f $request_filename) { rewrite ^/basic_cake/(.+)$ /basic_cake/index.php?url=$1 last; break; } } location /cake_test/ { index index.php; if (-f $request_filename) { break; } if (!-f $request_filename) { rewrite ^/cake_test/(.+)$ /cake_test/index.php?url=$1 last; break; } } # redirect server error pages to the static page /50x.html # error_page 500 502 503 504 /50x.html; location = /50x.html { root html; } # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000 # location ~ \.php$ { root html; fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include fastcgi_params; } } server { listen 8081; server_name localhost; root /srv/http/html/xsp; location / { index index.html index.htm index.aspx default.aspx; } location ~ \.(aspx|asmx|ashx|asax|ascx|soap|rem|axd|cs|config|dll)$ { fastcgi_pass 127.0.0.1:9001; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include fastcgi_params; } } } The problem that I have is that the css and images will not load from the webroot.

  • Object detection in bitmap JavaScript canvas

    - by fallenAngel
    I want to detect clicks on canvas elements which are drawn using paths. So far I have stored element paths in a JavaScript data structure and then check the coordinates of hits which match the element's coordinates. Rendering each element path and checking the hits would be inefficient when there are a lot of elements. I believe there must be an algorithm for this kind of coordinate search, can anyone help me with this?

    in MVC3 razor we found that their is no way to watch the design in Visual studio as well we can see aspx file by going to design mode. their is a little trick to solve this issue first is that if you have Expression web or Vs 2008 then open the file on them how see here in expression web 4 you need to add the extension .cshtml and open them as html as we open other. in Visual studio 2008 you need to add the extension .cshtml and set them open as html. well their is no big trouble if design not worked. but in some case when you need to get this issue solved this need to be work for configuration do this: Expression Web 4 > tools > application options > configure editor > click on new extension icon show in exact left put the cshtml in the window they show you and choose expression web [open as html] after that you can see the design in expression web. by default Expression web not have cshtml as known extension so you need to do that to add them because without it they never handle cshtml file and refer them to Visual studio. after setting this you  EW4 open the cshtml file as html and show you design in design mode. in Visual studio 2008 you can use same trick to solve this issue just follow this step > options > text editors > file extension put cshtml in textbox and set the option html editor from dropdown and click on add and ok this will open your cshtml file as html.

  • How can I call a URL as a cron job in Webmin?

    - by EmmyS
    (Possibly this belongs on stackoverflow, although it's not really a programming issue since the code works when run directly. If it needs to be moved, though, no problem.) I have a PHP file (which consumers a National Weather Service web service via SOAP, if it matters) that I need to run on a scheduled basis. I'm trying to set up a cron job in Webmin. If I use an absolute path to the file in the Command field, when I run it I get some strange errors: /var/www/html/mysite.com/test/ndfdXMLclient.php: line 1: ?php: No such file or directory /var/www/html/mysite.com/test/ndfdXMLclient.php: line 2: //: is a directory /var/www/html/mysite.com/test/ndfdXMLclient.php: line 3: //DOCUMENTATION: No such file or directory /var/www/html/mysite.com/test/ndfdXMLclient.php: line 4: //: is a directory /var/www/html/mysite.com/test/ndfdXMLclient.php: line 5: syntax error near unexpected token `"running client code",' /var/www/html/mysite.com/test/ndfdXMLclient.php: line 5: `error_log("running client code", 1, "[email protected]");' The actual code in my file for those 5 lines looks like this: <?php // *************************************************************************** //DOCUMENTATION FROM WEATHER.GOV ALL STORED IN xmlClientComments.txt // *************************************************************************** error_log("running client code", 1, "[email protected]"); The code runs perfectly fine when I run it directly in my browser, so why doesn't webmin recognize it as code? (The same thing happens if I enter the actual URL in the command field - http://mysite.com/test/ndfdXMLclient.php.) I've never worked with webmin before; most of our hosts' cron control panels allow cron jobs to run PHP files like this with no issue. Is there some trick to getting webmin to read php as actual php?

  • BizTalk 2009 - Scoped Record Counting in Maps

    - by StuartBrierley
    Within BizTalk there is a functoid called Record Count that will return the number of instances of a repeated record or repeated element that occur in a message instance. The input to this functoid is the record or element to be counted. As an example take the following Source schema, where the Source message has a repeated record called Box and each Box has a repeated element called Item: An instance of this Source schema may look as follows; 2 box records - one with 2 items and one with only 1 item. Our destination schema has a number of elements and a repeated box record.  The top level elements contain totals for the number of boxes and the overall number of items.  Each box record contains a single element representing the number of items in that box. Using the Record Count functoid it is easy to map the top level elements, producing the expected totals of 2 boxes and 3 items: We now need to map the total number of items per box, but how will we do this?  We have already seen that the record count functoid returns the total number of instances for the entire message, and unfortunately it does not allow you to specify a scoping parameter.  In order to acheive Scoped Record Counting we will need to make use of a combination of functoids. As you can see above, by linking to a Logical Existence functoid from the record/element to be counted we can then feed the output into a Value Mapping functoid.  Set the other Value Mapping parameter to "1" and link the output to a Cumulative Sum functoid. Set the other Cumulative Sum functoid parameter to "1" to limit the scope of the Cumulative Sum. This gives us the expected results of Items per Box of 2 and 1 respectively. I ran into this issue with a larger schema on a more complex map, but the eventual solution is still the same.  Hopefully this simplified example will act as a good reminder to me and save someone out there a few minutes of brain scratching.

  • Is this a link scheme? If so, what to do? what problems can i face?

    - by guisasso
    I was asked to remodel a website, and decided to check its rank on alexa. Surprisingly, there are many, many different websites linking to it, none relevant. One particular thing about it is that none of these urls work, and they all display the exact same error when accessed, which to me is a very good indication that this is some sort of linking scheme. (besides the somewhat obvious names, it even says scheme in one of the urls !?) If so, how should i proceed about this website? What can i do if this is in fact a scheme, how can this hurt the website, what types of problems can i face, and what can i do about it? addurlnow . info dirlist15.addurlnow . info/Business___Economy/Services/page-12.html linkdirectory101 . info dirlist16.linkdirectory101 . info/Business___Economy/Services/page-15.html seonetblog . info dirlist52.seonetblog . info/Business___Economy/Affiliate_Schemes addurls . us dirlist21.addurls . us/Business___Economy/Services/page-10.html webdirectoriessite . info dirlist20.webdirectoriessite . info/Business___Economy/Services/page-6.html addurlstore . info dirlist10.addurlstore . info/business___economy/services/page-14.html ukwebdirectorys . info dirlist21.ukwebdirectorys . info/Business___Economy/Services/page-13.html

  • How many copies are needed to enlarge an array?

    - by user10326
    I am reading an analysis on dynamic arrays (from the Skiena's algorithm manual). I.e. when we have an array structure and each time we are out of space we allocate a new array of double the size of the original. It describes the waste that occurs when the array has to be resized. It says that (n/2)+1 through n will be moved at most once or not at all. This is clear. Then by describing that half the elements move once, a quarter of the elements twice, and so on, the total number of movements M is given by: This seems to me that it adds more copies than actually happen. E.g. if we have the following: array of 1 element +--+ |a | +--+ double the array (2 elements) +--++--+ |a ||b | +--++--+ double the array (4 elements) +--++--++--++--+ |a ||b ||c ||c | +--++--++--++--+ double the array (8 elements) +--++--++--++--++--++--++--++--+ |a ||b ||c ||c ||x ||x ||x ||x | +--++--++--++--++--++--++--++--+ double the array (16 elements) +--++--++--++--++--++--++--++--++--++--++--++--++--++--++--++--+ |a ||b ||c ||c ||x ||x ||x ||x || || || || || || || || | +--++--++--++--++--++--++--++--++--++--++--++--++--++--++--++--+ We have the x element copied 4 times, c element copied 4 times, b element copied 4 times and a element copied 5 times so total is 4+4+4+5 = 17 copies/movements. But according to formula we should have 1*(16/2)+2*(16/4)+3*(16/8)+4*(16/16)= 8+8+6+4=26 copies of elements for the enlargement of the array to 16 elements. Is this some mistake or the aim of the formula is to provide a rough upper limit approximation? Or am I missunderstanding something here?

  • How to make subdirectory the document root of a web domain or localhost

    - by Ben Huh
    I have a subdirectory abc in the document root /var/www/html I want to be able to run any file any_file.html within the subdirectory by typing in the browser: localhost/any_file instead of localhost/abc/any_file.html or my_domain.com/any_file instead of my_domain.com/abc/any_file.html I tried writing in httpd.conf: <Directory "/var/www/html/abc"> RewriteEngine On RewriteBase / RewriteRule %{REQUEST_FILENAME} %{REQUEST_FILENAME}\.html </Directory> But it doesn't work.

  • Help on using mod_rewrite to serve I18N static site

    - by Guandalino
    My static site www.example.com is translated in different languages and files are organized in this hierarchy: / /de index.html seite-1.html /en index.html page-1.html /it index.html pagina-1.html The root contains no files, just one subdirectory for each language the site is translated in, while subdirectories contain pages translated (both content and file name are) in the language corresponding to subdirectory name, de, en, it, etc. The question is: how to configure mod_rewrite so that when a client visits www.example.com it is taken to the correct version of the site, falling back to english version if the required locale is not supported (i.e. Accept-Language header doesn't exist or specifies a language for which the site is not available, e.g. fr)? Thanks for any pointer, I'm here to provide further details or feedback! Best regards

  • Regex to String generation

    - by Mifmif
    Let's say that we have a regex and an index i , if we suppose that the set of string that match our regex are sorted in a lexicographical order, how could we get the i element of this list ? Edit : I added this simple example for more explanation : input : regex="[a-c]{1,2}"; index=4; in this case the ordered list of string that matches this regex contains those elements : a aa ab ac b ba bb bc c ca cb cc output : the 4th element which is ac ps: it's known that the string list that match the regex have infinite element, this doesn't have an impact on the proccess of extracting the element in the given index.
