  • Html5: How to handle RGB pixel with commands from prompt ? (just a browser)

    - by Rocket Surgeon
    In the browser tools, say in debugging (any browser will do, but IE9 preferred) how can I access things like html5 canvas and modify individual pixels by typing commands from prompt ? I know, it is possible to accomplish in miriad normal ways with preparing the markup and loading the page, but what is the shortest path ? The browser is running with some content, then I hit F12-Console- what exactly should I type to cause a canvas to change ? Thank you

  • Using polygons instead of quads on Cocos2d

    - by rraallvv
    I've been looking under the hood of Cocos2d, and I think (please correct me if I'm wrong) that although working with quads is a key feature of the engine, it should't be dificult to make it work with arrays of vertices (aka polygons) instead of quads, being the quads a special case of an array of four vertices by the way, does anyone have any code that makes cocos2d render a texture filled polygon inside a batch node? the code posted here (http://www.cocos2d-iphone.org/forum/topic/8142/page/2#post-89393) does a nice job rendering a texture filled polygon but the class doesn't work with batch nodes

  • Design Patterns - Why the need for interfaces?

    - by Kyle Johnson
    OK. I am learning design patterns. Every time I see someone code an example of a design pattern they use interfaces. Here is an example: http://visualstudiomagazine.com/Articles/2013/06/18/the-facade-pattern-in-net.aspx?Page=1 Can someone explain to me why was the interfaces needed in this example to demonstrate the facade pattern? The program work if you pass in the classes to the facade instead of the interface. If I don't have interfaces does that mean

  • Is there any way to lock down Photoshop to prevent designers from creating styles that cannot be rendered in CSS?

    - by Hugo Rodger-Brown
    Photoshop is a much more powerful design tool than CSS, and given free reign to design at will, designers will often tweak things like font settings to a degree that cannot be recreated on the web. Is there any way to lock down Photoshop, or perhaps run an equivalent of the Office 2010 "Compatability report" that shows the designer where they have designed something that cannot be rendered on a web page. Something like the old-school "web-safe" colour palette, but for an overall design.

  • ASP.NET Horizontal Menu Control

    A few weeks ago, I was working on an ASP.NET web application and needed a simple horizontal menu with a submenu. I decided to use ASP.NET's Menu control: Just drag and drop the control on to the page. Simple enough, but the control did not provide access key and target window support on menu items. I have put together a tutorial on how to include an access key attribute, include a target attribute, and include a site map path.

  • Star rating not showing in rich snippets

    - by Danny R
    We've recently been doing a lot of work on our site's SEO (www.betterthanreviews.com). We recently did a push to update the rich snippets breadcrumb, meta description, and star rating. After giving Google some time to index the site, it has updated the breadcrumbs and meta descriptions for our review pages, but the stars are still not showing. This is currently how it appears on a Google search (link to the actual page: http://www.betterthanreviews.com/home-security/livewatch): This is what the Rich Snippets is supposed to look like, and how it appears in Google's testing tool: More context: As seen in our html, we are using schema.org language. We initially were using schema.org/Corporation for the site, but we now have the page labeled as schema.org/HomeAndConstructionBusiness because Google will not show star ratings for the Corporation language. However, in our Webmaster Tools, the Structured Data is still showing the Corporation language, which could be a potential issue. Here is a look at some of the coding that we used. But it can be looked at closer by inspecting the element: <div class="aggregate-rating" itemprop="aggregateRating" itemscope="" itemtype="http://schema.org/AggregateRating"> <div class="review row_fluid" itemprop="review" itemscope="" itemtype="http://schema.org/Review"> <div class="row_fluid rating" itemprop="reviewRating" itemscope="" itemtype="http://schema.org/Rating"> <meta content="4.5" itemprop="ratingValue" title="4.5 out of 5 stars" class="star-rating-readonly"> <meta content="2013-12-05" itemprop="datePublished"> <p class="review-headline" itemprop="headline">Way better than my previous system</p> <div> <p class="reviewer" itemprop="author">Scott H. </p> <span class="bullet">•</span> <p class="created_at">2 months ago</p> <p class="content" itemprop="description">I love it! The experience I have had so far is extremely positive. I had another alarm system before and I didn't like it but this one is really nice. I am telling everybody about it.</p> </div> </div> Any suggestions for how to fix this?

  • Display only visits referred from a Google Adwords campain

    - by Adjam
    I want to only display visits to my site which were sent by my Google Adwords campain preferably in the Visitors overview page. I've tried filtering with 'Advanced Segments' but when I select "Paid Search Traffic" visits goes down to zero. But I do know that most of my visitors at the moment are being sent from Google Adwords. In this question the answer (which was not chosen) suggested adding a HTTP GET request or an URL shortener, but surly there is a way to do it in Analytics?

  • Retroactively applying a Piwik goal to visitors

    - by Andrew Aylett
    I started receiving a large (for me) amount of traffic on one of my pages yesterday. Today, I thought that it would be useful to track goals from that page -- there's a link to my blog from it. I added the 'visited external link' goal to Piwik, and new visits are being recorded. However, it seems to me that there must be enough data in the database to retroactively apply the goal to past users -- is there a way to achieve that?.

  • How to utilise a newly acquired keyword domain to contribute to an already existing healthy website?

    - by vDog
    My client's website has just reached spot 1 for the most valuable keyword. We acquired the domain that was at #1 spot. It's a keyword domain (targetkeyword.tld). Just wondering what would be the best way to make use of it. A permanent redirect or a single page that hyperlinks to the brand website? Should I be concerned about anything negative associated to this keyword domain (poor backlinks and the fact that this website was down for about one month)?

  • URL routing similar to Facebook (related to AJAX and the URL)

    - by Guilherme Cardoso
    In this article i'm gonna show you how i do when i have to update some content with AJAX and i have to change the URL. First, let's see an example to understand it better. If the user is reading a News with Id 1 and he clicked on another News with Id 2, if we update the content with AJAX the user is now reading the News Id 2 but the URL remains the same, for example: http://localhost/News/Read/1 Now let's see another example from Facebook. If i'm reading my profile and i click on Photos, Facebook updates it with AJAX and the URL switch to: http://www.facebook.com/guilhermegeek#!/guilhermegeek?sk=photos If we enter on that URL, it's mapped to: http://www.facebook.com/guilhermegeek?sk=photos The trick here is the parameters that we use after the #!. Those parameters are never sent to the server side, so we handle them on the client side (javascript).In the example of Facebook, he receives my profile name (guilhermegeek) and the action is to read photos. A few time ago i've written an article in my Portuguese blog explaining how to use an alternative to clients with javascript disabled. Like this: <a onclick="javascript:ReadNews(id);" href="#!News/Read/@id/">Title</a> When the user enter the link of that news, my function Read(); fills the News in the page. Then, i add the #!News/Read/@id/ to my URL. It's gonna stay something like this: http://localhost/News/Read/1#!News/Read/2 As i explained before, the News that the user is reading has the Id 2.The next step is to use javascript to check if the URL that the user typed has other News Id, because if we enter on the above URL our controller will get the Id 1 (everything after to the # isn't sent to the server side). $(document).ready(function () {             var h = window.location.hash;             if (h != null) {                 var parts = window.location.href.split('#!');                 if (parts.length > 1) {                     window.location.replace("http://localhost/" + parts[1]);                 }             }    }); It's pretty simple. I'm cutting everything after the #!, then i redirect the user to a new page. So, it's gonna stay:http://localhost/News/Read/2

  • Persisting Session Between Different Browser Instances

    - by imran_ku07
        Introduction:          By default inproc session's identifier cookie is saved in browser memory. This cookie is known as non persistent cookie identifier. This simply means that if the user closes his browser then the cookie is immediately removed. On the other hand cookies which stored on the user’s hard drive and can be reused for later visits are called persistent cookies. Persistent cookies are less used than nonpersistent cookies because of security. Simply because nonpersistent cookies makes session hijacking attacks more difficult and more limited. If you are using shared computer then there are lot of chances that your persistent session will be used by other shared members. However this is not always the case, lot of users desired that their session will remain persisted even they open two instances of same browser or when they close and open a new browser. So in this article i will provide a very simple way to persist your session even the browser is closed.   Description:          Let's create a simple ASP.NET Web Application. In this article i will use Web Form but it also works in MVC. Open Default.aspx.cs and add the following code in Page_Load.    protected void Page_Load(object sender, EventArgs e)        {            if (Session["Message"] != null)                Response.Write(Session["Message"].ToString());            Session["Message"] = "Hello, Imran";        }          This page simply shows a message if a session exist previously and set the session.          Now just run the application, you will just see an empty page on first try. After refreshing the page you will see the Message "Hello, Imran". Now just close the browser and reopen it or just open another browser instance, you will get the exactly same behavior when you run your application first time . Why the session is not persisted between browser instances. The simple reason is non persistent session cookie identifier. The session cookie identifier is not shared between browser instances. Now let's make it persistent.          To make your application share session between different browser instances just add the following code in global.asax.    protected void Application_PostMapRequestHandler(object sender, EventArgs e)           {               if (Request.Cookies["ASP.NET_SessionIdTemp"] != null)               {                   if (Request.Cookies["ASP.NET_SessionId"] == null)                       Request.Cookies.Add(new HttpCookie("ASP.NET_SessionId", Request.Cookies["ASP.NET_SessionIdTemp"].Value));                   else                       Request.Cookies["ASP.NET_SessionId"].Value = Request.Cookies["ASP.NET_SessionIdTemp"].Value;               }           }          protected void Application_PostRequestHandlerExecute(object sender, EventArgs e)        {             HttpCookie cookie = new HttpCookie("ASP.NET_SessionIdTemp", Session.SessionID);               cookie.Expires = DateTime.Now.AddMinutes(Session.Timeout);               Response.Cookies.Add(cookie);         }          This code simply state that during Application_PostRequestHandlerExecute(which is executed after HttpHandler) just add a persistent cookie ASP.NET_SessionIdTemp which contains the value of current user SessionID and sets the timeout to current user session timeout.          In Application_PostMapRequestHandler(which is executed just before th session is restored) we just check whether the Request cookie contains ASP.NET_SessionIdTemp. If yes then just add or update ASP.NET_SessionId cookie with ASP.NET_SessionIdTemp. So when a new browser instance is open, then a check will made that if ASP.NET_SessionIdTemp exist then simply add or update ASP.NET_SessionId cookie with ASP.NET_SessionIdTemp.          So run your application again, you will get the last closed browser session(if it is not expired).   Summary:          Persistence session is great way to increase the user usability. But always beware the security before doing this. However there are some cases in which you might need persistence session. In this article i just go through how to do this simply. So hopefully you will again enjoy this simple article too.

  • Where do I file bugs for the Ubuntu One music client for Android?

    - by Jorge Castro
    I've recently started using the Ubuntu One Music streaming client for Android. From the web page it says that the android app is based on Subsonic. I want to file bugs on the app, mostly feature requests and things like that, and from looking at the screenshots, the application seems to be Subsonic preconfigured to use my U1 music collection. Is it appropriate for me to file feature requests with Subsonic, or is there a Launchpad project where we're supposed to file bugs which are then vetted and sent upstream?
