  • Can SpriteBatch be used to fill a polygon with a texture?

    - by can poyrazoglu
    I basically need to fill a texture into a polygon using the SpriteBatch. I've done some research but couldn't find anything useful except polygon triangulation method, which works well only with convex polygons (without diving into super math which is definitely not something I'm pretty good at). Are there any solutions for filling in a polygon in a basic way? I of course need something dynamic (I'll have a map editor that you can define polygons, and the game will render them (and collision detection will also use them but that's off topic), basically I can't accept solutions like "pre-calculated" bitmaps or anything like that. I need to draw a polygon with the segments provided, to the screen, using the SpriteBatch.

  • Silverlight Reporting Application Part 3.5 - Prism Background and WCF RIA [Series Intermission]

    Taking a step back before I dive into the details and full-on coding fun, I wanted to once again respond to a comment on my last post to clear up some things in regards to how I'm setting up my project and some of the choices I've made. Aka, thanks Ben. :) Prism Project Setup For starters, I'm not the ideal use case for a Prism application. In most cases where you've got a one-man team, Prism can be overkill as it is more intended for large teams who are geographically dispersed or in applications that have a larger scale than my Recruiting application in which you'll greatly benefit from modularity, delayed loading of xaps, etc. What Prism offers, though, is a manner for handling UI, commands, and events with the idea that, through a modular approach in which no parts really need to know about one another, I can update this application bit by bit as hiring needs change or requirements differ between offices without having to worry that changing something in the Jobs module will break something in, say, the Scheduling module. All that being said, here's a look at how our project breakdown for Recruit (MVVM/Prism implementation) looks: This could be a little misleading though, as each of those modules is actually another project in the overall Recruit solution. As far as what the projects actually are, that looks a bit like this: Recruiting Solution Recruit (Shell up there) - Main Silverlight Application .Web - Default .Web application to host the Silverlight app Infrastructure - Silverlight Class Library Project Modules - Silverlight Class Library Projects Infrastructure &Modules The Infrastructure project is probably something you'll see to some degree in any composite application. In this application, it is going to contain custom commands (you'll see the joy of these in a post or two down the road), events, helper classes, and any custom classes I need to share between different modules. Think of this as a handy little crossroad between any parts of your application. Modules on the other hand are the bread and butter of this application. Besides the shell, which holds the UI skeleton, and the infrastructure, which holds all those shared goodies, the modules are self-contained bundles of functionality to handle different concerns. In my scenario, I need a way to look up and edit Jobs, Applicants, and Schedule interviews, a Notification module to handle telling the user when different things are happening (i.e., loading from database), and a Menu to control interaction and moving between different views. All modules are going to follow the following pattern: The module class will inherit from IModule and handle initialization and loading the correct view into the correct region, whereas the Views and ViewModels folders will contain paired Silverlight user controls and ViewModel class backings. WCF RIA Services Since we've got all the projects in a single solution, we did not have to go the route of creating a WCR RIA Services Class Library. Every module has it's WCF RIA link back to the main .Web project, so the single Linq-2-SQL (yes, I said Linq-2-SQL, but I'll soon be switching to OpenAccess due to the new visual designer) context I'm using there works nicely with the scope of my project. If I were going for completely separating this project out and doing different, dynamically loaded elements, I'd probably go for the separate class library. Hope that clears that up. In the future though, I will be using that in a project that I've got in the "when I've got enough time to work on this" pipeline, so we'll get into that eventually- and hopefully when WCF RIA is in full release! Why Not use Silverlight Navigation/Business Template? The short answer- I'm a creature of habit, and having used Silverlight for a few years now, I'm used to doing lots of things manually. :) Plus, starting with a blank slate of a project I'm able to set up things exactly as I want them to be. In this case, rather than the navigation frame we would see in one of the templates, the MainRegion/ContentControl is working as our main navigation window. In many cases I will use theSilverlight navigation template to start things off, however in this case I did not need those features so I opted out of using that. Next time when I actually hit post #4, we're going to get into the modules and starting to get functionality into this application. Next week is also release week for the Q1 2010 release, so be sure to check out our annualWebinar Week (I might be biased, but Wednesday is my favorite out of the group). Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

  • Some websites are not opening in any web browser (firefox/chrome). What should I do? [closed]

    - by Jamal
    Some websites are not opening in my system. I am using Ubuntu 12.10. Earlier, when I was using Ubuntu 10.10,11.10 there was no such issue. The problem was started in ubuntu 12.04, but it remained the same even after formatting and installing ubuntu 12.10. I have tried Firefox as well as Chromium and I am sure the issue is not with the browser. same websites are opening perfectly with Windows. Google, Twitter and Ubuntu related websites are running perfect. Other websites like www.downrightnow.com, easy-mantra.com, facebook.com, sourceforge.net are not opening. Installed dual boot with win xp. Ubuntu 12.10 is 64 bit.

  • Worth changing the URL structure to incorporate keywords?

    - by Dejan Pelzel
    I am migrating my blog from PHP to ASP.NET and while recoding the whole website, I figured I might as well improve the URL structure. This is how an url looks like now: example.com/blog/post/755/hakurei-reimu-cosplay-from-touhou-by-kishigami-hana and this is hould it will look after the change (cosplay being the dynamic main keyword of the post): example.com/blog/cosplay/hakurei-reimu-cosplay-from-touhou-by-kishigami-hana-755/ The website is a bit more than a half year old and receives around 650k page views a month, mainly from search traffic. Of course everything would be redirected with 301 redirects. Do you think it is worth changing to a new URL structure, or will it harm the ranking in the long run?

  • What are QUICK interview questions for the Microsoft stack development jobs?

    - by Dubmun
    I'm looking for your best "quick answer" technical interview questions. We are a 100% Microsoft shop and do the majority of our development on the ASP.NET web stack in C# and have a custom SOA framework also written in C#. We use a combination of Web Forms, MVC, Web Services, WCF, Entity Framework, SQL Server, TSQL, jQuery, LINQ, and TFS in a SCRUM environment. We are currently on .NET 3.5 with a very near transition to .NET 4.0. Our interviewing process includes a 55 minute interview with two technical people (usually an architect and a senior developer). The two interviewers have to share the time for questions. That isn't enough time for very many true programming problems so I'm looking for more good questions that have quick, yet meaningful, answers. We are mainly interviewing for Senior Dev positions right now but may interview for some Juniors in the future. Please help?

  • Resources on concepts/theory behind GUI development?

    - by ShrimpCrackers
    I was wondering if there were any resources that explain concepts/theory behind GUI development. I don't mean a resource that explains how to use a GUI library, but rather how to create your own widgets. For example a resource that explains different methods on how to implement scrollable listboxes. I ask because I have an idea for a game tool where I would like to create my own widgets and let users drag and drop them onto some kind of form. How do GUI libraries usually draw widgets? I'm not sure if reskinning widgets from a GUI library fits my needs, since widget behavior needs to be dynamic based on user interaction.

  • Mark Hurd on the Customer Revolution: Oracle's Top 10 Insights

    - by Richard Lefebvre
    Reprint of an article from Forbes Businesses that fail to focus on customer experience will hear a giant sucking sound from their vanishing profitability. Because in today’s dynamic global marketplace, consumers now hold the power in the buyer-seller equation, and sellers need to revamp their strategy for this new world order. The ability to relentlessly deliver connected, personalized and rewarding customer experiences is rapidly becoming one of the primary sources of competitive advantage in today’s dynamic global marketplace. And the inability or unwillingness to realize that the customer is a company’s most important asset will lead, inevitably, to decline and failure. Welcome to the lifecycle of customer experience, in which consumers explore, engage, shop, buy, ask, compare, complain, socialize, exchange, and more across multiple channels with the unconditional expectation that each of those interactions will be completed in an efficient and personalized manner however, wherever, and whenever the customer wants. While many niche companies are offering point solutions within that sprawling and complex spectrum of needs and requirements, businesses looking to deliver superb customer experiences are still left having to do multiple product evaluations, multiple contract negotiations, multiple test projects, multiple deployments, and–perhaps most annoying of all–multiple and never-ending integration projects to string together all those niche products from all those niche vendors. With its new suite of customer-experience solutions, Oracle believes it can help companies unravel these challenges and move at the speed of their customers, anticipating their needs and desires and creating enduring and profitable relationships. Those solutions span the full range of marketing, selling, commerce, service, listening/insights, and social and collaboration tools for employees. When Oracle launched its suite of Customer Experience solutions at a recent event in New York City, president Mark Hurd analyzed the customer experience revolution taking place and presented Oracle’s strategy for empowering companies to capitalize on this important market shift. From Hurd’s presentation and related materials, I’ve extracted a list of Hurd’s Top 10 Insights into the Customer Revolution. 1. Please Don’t Feed the Competitor’s Pipeline!After enduring a poor experience, 89% of consumers say they would immediately take their business to your competitor. (Except where noted, the source for these findings is the 2011 Customer Experience Impact (CEI) Report including a survey commissioned by RightNow (acquired by Oracle in March 2012) and conducted by Harris Interactive.) 2. The Addressable Market Is Massive. Only 1% of consumers say their expectations were always met by their actual experiences. 3. They’re Willing to Pay More! In return for a great experience, 86% of consumers say they’ll pay up to 25% more. 4. The Social Media Microphone Is Always Live. After suffering through a poor experience, more than 25% of consumers said they posted a negative comment on Twitter or Facebook or other social media sites. Conversely, of those consumers who got a response after complaining, 22% posted positive comments about the company. 5.  The New Deal Is Never Done: Embrace the Entire Customer Lifecycle. An appropriately active and engaged relationship, says Hurd, extends across every step of the entire processs: need, research, select, purchase, receive, use, maintain, and recommend. 6. The 360-Degree Commitment. Customers want to do business with companies that actively and openly demonstrate the desire to establish strong and seamless connections across employees, the company, and the customer, says research firm Temkin Group in its report called “The CX Competencies.” 7. Understand the Emotional Drivers Behind Brand Love. What makes consumers fall in love with a brand? Among the top factors are friendly employees and customer reps (73%), easy access to information and support (55%), and personalized experiences, such as when companies know precisely what products or services customers have purchased in the past and what issues those customers have raised (36%). 8.  The Importance of Immediate Action. You’ve got one week to respond–and then the opportunity’s lost. If your company needs more than a week to answer a prospect’s question or request, most of those prospects will terminate the relationship. 9.  Want More Revenue, Less Churn, and More Referrals? Then improve the overall customer experience: Forrester’s research says that approach put an extra $900 million in the pockets of wireless service providers, $800 million for hotels, and $400 million for airlines. 10. The Formula for CX Success.  Hurd says it includes three elegantly interlaced factors: Connected Engagement, to personalize the experience; Actionable Insight, to maximize the engagement; and Optimized Execution, to deliver on the promise of value.

  • How do I add changes resolv.conf without getting overwritten?

    - by Sam
    I have migrated to 12.04 from 7.10 finally. I have one last part to complete but I am stumped. I am using puppet on each server, and in the past have used resolv.conf to point to my search to the puppetmaster. search puppetmaster.com nameserver 192.168.1.XXX When trying to use the file on 12.04 resolv.conf the file gets over written when rebooted. I cannot use a static IP for these, so using the /etc/network/interfaces to help me out is a nill point. # Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8) # DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN nameserver 127.0.0.1 Is there a way to get resolvconf to handle this either in the head, tail or base. If there is, are there any examples I can use to tweak on my server. Any help is much appreciated.

  • Programmatically adding metatags to Masterpages in Web Forms and MVC [migrated]

    - by Mike Clarke
    Has anyone got any ideas on where we should be adding our SEO metadata in a Web Forms project? Why I ask is that currently I have two main Masterpages, one is the home page and the other one is every other page, they both have the same metadata that’s just a generic description and set of key words about my site. The problem with that is search engines are only picking up my home page and my own search engine displays the same title and description for all results. The other problem is the site is predominantly dynamic so if you type in a search for beach which is a major categories on the site you get 10000 results that all go to different information but all look like a link to the same page to the user. edit It's live here www.themorningtonpeninsula.com

  • Solving 2D Collision Detection Issues with Relative Velocities

    - by Jengerer
    Imagine you have a situation where two objects are moving parallel to one-another and are both within range to collide with a static wall, like this: A common method used in dynamic collision detection is to loop through all objects in arbitrary order, solve for pair-wise collision detection using relative velocities, and then move the object to the nearest collision, if any. However, in this case, if the red object is checked first against the blue one, it would see that the relative velocity to the blue object is -20 m/s (and would thereby not collide this time frame). Then it would see that the red object would collide with the static wall, and the solution would be: And the red object passes through the blue one. So it appears to be a matter of choosing the right order in which you check collisions; but how can you determine which order is correct? How can this passing through of objects be avoided? Is ignoring relative velocity and considering every object as static during pair-wise checks a better idea for this reason?

  • How do I grok NHibernate's QueryOver API?

    - by Brant Bobby
    I've run into the limits of what NHibernate 3.0's LINQ provider is capable of and decided it's time to learn about one of the more powerful (or at least feature-complete) options: the QueryOver API. The problem is, I have zero experience with ICriteria, and all of the tutorials I've been able to find online either: Assume I'm an ICriteria expert and simply show me how to convert ICriteria code to the new fluent interface, or Are trivial "here's how you do an inner join" examples that don't really help me understand more complex concepts like projections, subqueries, requirements, or whatever other magic the API is capable of. What should I read to really learn about QueryOver, and how to make full use of it?

  • Do CDNs work with POST operations?

    - by iddqd
    I'm using a CDN (Level3) for the first time and I'm a bit confused. I'm accessing dynamic URLs such as http://cdn.mysite.com?getItem=1234 that return text data. Do CDNs work with HTTP POST operations? When i issue a HTTP POST operation, my "real" server receives this request every time, so I'm wondering if the CDN has a problem with POST operations. If i use HTTP GET it seems to work, i call the URL once (from my application), i can see my server receiving the request. If i call it a second time, the CDN delivers it directly, my server doesn't get anything. However if i open same the link manually from a second browser tab, my server is asked to deliver again, shouldn't it be cached by now? Many thanks.

  • Understanding how texCUBE works and writing cubemaps properly into a cube rendertarget

    - by cubrman
    My goal is to create accurate reflections, sampled from a dynamic cubemap, for specific 3d objects (mostly lights) in XNA 4.0. To sample the cubemap I compute the 3d reflection vector in a classic way: half3 ReflectionVec = reflect(-directionToCamera, Normal.rgb); I then use the vector to get the actual reflected color: half3 ReflectionCol = texCUBElod(ReflectionSampler, float4(ReflectionVec, 0)); The cubemap I am sampling from is a RenderTarget with 6 flat faces. So my question is, given the 3d world position of an arbitrary 3d object, how can I make sure that I get accurate reflections of this object, when I re-render the cubemap. Should I build the ViewProjection matrix in a specific way? Or is there any other approach?

  • VMware sharing folders between Win7 (host) and Ubuntu (guest)

    - by Pawel Goscicki
    What is the best way to share a folder between Win7 64bit (host) and Ubuntu 10.10 (guest) in VMware player? I can setup the sharing just fine (using vmware-tools), but all shared files are root:root owned with 777 permission set. Which, well, sucks. What can I do to have shared files with preserved ownership and permissions? I'm guessing I would need some kind of a file container, that would get mounted in Ubuntu as a block device (if so, it would need to be dynamic, i.e. expand with size of contained files). But maybe there is a better solution?

  • How do I set up hosting a domain name at home with Apache?

    - by Andrew McIntyre
    I am relatively new to Ubuntu Linux and I am struggling to figure out the basic set-up of hosting a domain name at home with Apache2. I understand that you have to change your IP from dynamic to a static IP Address but I am not sure how you achieve that step. I am looking for some assistance on this on how to enable self signing certificates, make the domain name resolve on the Internet from hosting the website on the web server, enabling protected directories and the basic commands of accessing the directory where the website files can be uploaded and available on the World Wide Web.

  • Is there a quasi-standard set of attributes to annotate thread safety, immutability etc.?

    - by Eugene Beresovksy
    Except for a blog post here and there, describing the custom attributes someone created, but that do not seem to get any traction - like one describing how to enforce immutability, another one on Documenting Thread Safety, modeling the attributes after JCIP annotations - is there any standard emerging? Anything MS might be planning for the future? This is something that should be standard, if there's to be any chance of interoperability between libraries concurrency-wise. Both for documentation purposes, and also to feed static / dynamic test tools. If MS isn't doing anything in that direction, it could be done on CodePlex - but I couldn't find anything there, either. <opinion>Concurrency and thread safety are really hard in imperative and object-languages like C# and Java, we should try to tame it, until we hopefully switch to more appropriate languages.</opinion>

  • Rendering oily/polluted water?

    - by Fraser
    Any shader wizards out there have an idea of how to achieve an oily/polluted water effect, similar to this: Ideally, the water would not be uniformly oily, but instead the oil could be generated from some source (such as a polluting drain from a chemical plant) and then diffuse throughout the water body. My thought for this part would be to keep an "oil map" as a 2D texture that determines the density of oil at each point on the water surface. It would diffuse and move naturally with the water vel;ocity at that point (I have a wave-particle simulation for dynamic waves, and am already doing something similar for foam on the water surface). However, I'm not sure how physically correct that would be, since oil might not move at the same velocity as the water. And I have no idea how to make all those trippy colors :-). Thoughts?

  • Correctly indexing multiple domains with same content in Google and others

    - by AJweb
    I have a client with a dozen territorial domains, like mydomain.co.uk, mydomain.fr, mydomain.de, etc Most of these domains hold a different language of the same dynamic content (shop), but some, like co.uk and .com, have the same language and content, except for some content customized to each country/domain in the front page, contact and other pages. I am aware that we should use the canonical meta tag to mark those duplicated contents, but, we want the co.uk to be present in UK ( indexed in google.co.uk ) and the .com to be present in US and other countries, for example, or least that is the goal. Is there anything we can do to "help" google determine the geographical meaning of each domain? If we mark with canonical tag the .com and co.uk sites, do you know how google will decide which one to show on a given search?

  • HTTP 303 redirection and robots.txt

    - by Ian Dickinson
    On a site I'm working on, we're using the HTTP 303 redirect pattern (see this article for background) to distinguish between information and non-information resources. So: some URL's under /id get redirected to dynamically-created pages under /doc. These dynamic pages are built from a database, and contain links to other /doc/ resources, so in general we don't want them to be crawled. Our robots.txt contains: Disallow: /doc However, we do want the non-redirected pages under /id to get indexed by Google et al: Allow: /id So the question I have, which I can't find an answer to so far, is: if an allowed /id page 303-redirects to a /doc page, will it still be blocked by robots.txt? If yes, we're OK, but otherwise I'm going to disallow all /id resources in the robots file, as having the crawler hammer the db would be worse than losing search indexing for the /id pages.

  • Visual Tree Enumeration

    - by codingbloke
    I feel compelled to post this blog because I find I’m repeatedly posting this same code in silverlight and windows-phone-7 answers in Stackoverflow. One common task that we feel we need to do is burrow into the visual tree in a Silverlight or Windows Phone 7 application (actually more recently I found myself doing this in WPF as well).  This allows access to details that aren’t exposed directly by some controls.  A good example of this sort of requirement is found in the “Restoring exact scroll position of a listbox in Windows Phone 7”  question on stackoverflow.  This required that the scroll position of the scroll viewer internal to a listbox be accessed. A caveat One caveat here is that we should seriously challenge the need for this burrowing since it may indicate that there is a design problem.  Burrowing into the visual tree or indeed burrowing out to containing ancestors could represent significant coupling between module boundaries and that generally isn’t a good idea. Why isn’t this idea just not cast aside as a no-no?  Well the whole concept of a “Templated Control”, which are in extensive use in these applications, opens the coupling between the content of the visual tree and the internal code of a control.   For example, I can completely change the appearance and positioning of elements that make up a ComboBox.  The ComboBox control relies on specific template parts having set names of a specified type being present in my template.  Rightly or wrongly this does kind of give license to writing code that has similar coupling. Hasn’t this been done already? Yes it has.  There are number of blogs already out there with similar solutions.  In fact if you are using Silverlight toolkit the VisualTreeExtensions class already provides this feature.  However I prefer my specific code because of the simplicity principle I hold to.  Only write the minimum code necessary to give all the features needed.  In this case I add just two extension methods Ancestors and Descendents, note I don’t bother with “Get” or “Visual” prefixes.  Also I haven’t added Parent or Children methods nor additional “AndSelf” methods because all but Children is achievable with the addition of some other Linq methods.  I decided to give Descendents an additional overload for depth hence a depth of 1 is equivalent to Children but this overload is a little more flexible than simply Children. So here is the code:- VisualTreeEnumeration public static class VisualTreeEnumeration {     public static IEnumerable<DependencyObject> Descendents(this DependencyObject root, int depth)     {         int count = VisualTreeHelper.GetChildrenCount(root);         for (int i = 0; i < count; i++)         {             var child = VisualTreeHelper.GetChild(root, i);             yield return child;             if (depth > 0)             {                 foreach (var descendent in Descendents(child, --depth))                     yield return descendent;             }         }     }     public static IEnumerable<DependencyObject> Descendents(this DependencyObject root)     {         return Descendents(root, Int32.MaxValue);     }     public static IEnumerable<DependencyObject> Ancestors(this DependencyObject root)     {         DependencyObject current = VisualTreeHelper.GetParent(root);         while (current != null)         {             yield return current;             current = VisualTreeHelper.GetParent(current);         }     } }   Usage examples The following are some examples of how to combine the above extension methods with Linq to generate the other axis scenarios that tree traversal code might require. Missing Axis Scenarios var parent = control.Ancestors().Take(1).FirstOrDefault(); var children = control.Descendents(1); var previousSiblings = control.Ancestors().Take(1)     .SelectMany(p => p.Descendents(1).TakeWhile(c => c != control)); var followingSiblings = control.Ancestors().Take(1)     .SelectMany(p => p.Descendents(1).SkipWhile(c => c != control).Skip(1)); var ancestorsAndSelf = Enumerable.Repeat((DependencyObject)control, 1)     .Concat(control.Ancestors()); var descendentsAndSelf = Enumerable.Repeat((DependencyObject)control, 1)     .Concat(control.Descendents()); You might ask why I don’t just include these in the VisualTreeEnumerator.  I don’t on the principle of only including code that is actually needed.  If you find that one or more of the above  is needed in your code then go ahead and create additional methods.  One of the downsides to Extension methods is that they can make finding the method you actually want in intellisense harder. Here are some real world usage scenarios for these methods:- Real World Scenarios //Gets the internal scrollviewer of a ListBox ScrollViewer sv = someListBox.Descendents().OfType<ScrollViewer>().FirstOrDefault(); // Get all text boxes in current UserControl:- var textBoxes = this.Descendents().OfType<TextBox>(); // All UIElement direct children of the layout root grid:- var topLevelElements = LayoutRoot.Descendents(0).OfType<UIElement>(); // Find the containing `ListBoxItem` for a UIElement:- var container = elem.Ancestors().OfType<ListBoxItem>().FirstOrDefault(); // Seek a button with the name "PinkElephants" even if outside of the current Namescope:- var pinkElephantsButton = this.Descendents()     .OfType<Button>()     .FirstOrDefault(b => b.Name == "PinkElephants"); //Clear all checkboxes with the name "Selector" in a Treeview foreach (CheckBox checkBox in elem.Descendents()     .OfType<CheckBox>().Where(c => c.Name == "Selector")) {     checkBox.IsChecked = false; }   The last couple of examples above demonstrate a common requirement of finding controls that have a specific name.  FindName will often not find these controls because they exist in a different namescope. Hope you find this useful, if not I’m just glad to be able to link to this blog in future stackoverflow answers.

  • AdSense Custom Search Ads - custom quesry

    - by Alex
    i'm trying to set up a custom search ad, but I am nost sure about the query. On the site it says (https://developers.google.com/custom-search-ads/docs/implementation-guide) 'query' should be dynamic based on your page. This variable targets the ads and therefore should always match what the user on your site has just performed a search for. Now, what I understand is: I have to program my page so that the query variable contains some custom words. Am I right? If a user gets to my site through clicking on an adsense, there is no way to "know" what the user looked for and display my query accordingly, right? Thanks for any help!
