  • best option to create simple website mockup with navigation

    - by Buzzer
    I'm trying to put together a static html website with full navigation. In other words, I want the user to click some links and images and actually be taken to another page. I'm a developer so I know how to do this in frameworks like ASP.Net MVC and grails. However, for this particular case, I just want to quickly mock up the UI and provide simple navigation so I can do some user testing. Can anyone advice on how to do this? Thanks,

  • Criteria for selecting software for embedded device

    - by Suresh Kumar
    We are currently evaluating Web servers for an embedded device. We have laid down the evaluation criteria for things like HTTP version, Security, Compression etc. On the embeddable side, we have identified the following criteria: Memory footprint Memory management (support for plugging in a custom memory manager) CPU usage Thread usage (support for thread pool) Portability What I want inputs on is: Are there any other criteria that an embeddable software should meet? What exactly does it mean when someone says that a software is designed for embeddable use? We currently have zeroed in on two Web servers: AppWeb Lighttpd (lighty) Feature wise, both the above Web servers seem to be on par. However, it is claimed that AppWeb is designed for embedded use while Lighttpd is not. To choose between the above two Web servers, what criteria should I be looking at?

  • search engine crawling frequency

    - by Aditya Pratap Singh
    I want to design a search engine for news websites ie. download various article pages from these websites, index the pages, and answer search queries on the index. I want a short pseudocode to find an appropriate crawling frequency -- i do not want to crawl too often because the website may not have changed, and do not want to crawl too infrequently because index would then be out of date. Assume that crawling code looks as follows while(1) { sleep(sleep_interval); // sleep for sleep_interval crawl(website); // crawls the entire website diff = diff(currently_crawled_website, previously_crawled_website); // returns a % value of difference between the latest and previous crawls of the website sleep_interval = infer_sleep_interval(diff, sleep_interval); } looking for a pseudocode for the infer_sleep_interval method: long sleep_interval infer_sleep_interval(int diff_percentage,long previous_sleep_interval) { ... ... ... } i want to design method which adaptively alters the sleeping interval based on the update frequency of the website.

  • DirectX 9 HLSL vs. DirectX 10 HLSL: syntax the same?

    - by numerical25
    For the past month or so, I have been busting my behind trying to learn DirectX. So I've been mixing back back and forth between DirectX 9 and 10. One of the major changes I've seen in the two is how to process vectors in the graphics card. One of the drastic changes I notice is how you get the GPU to recognize your structs. In DirectX 9, you define the Flexible Vertex Formats. Your typical set up would be like this: #define CUSTOMFVF (D3DFVF_XYZRHW | D3DFVF_DIFFUSE) In DirectX 10, I believe the equivalent is the input vertex description: D3D10_INPUT_ELEMENT_DESC layout[] = { {"POSITION",0,DXGI_FORMAT_R32G32B32_FLOAT, 0 , 0, D3D10_INPUT_PER_VERTEX_DATA, 0}, {"COLOR",0,DXGI_FORMAT_R32G32B32A32_FLOAT, 0 , 12, D3D10_INPUT_PER_VERTEX_DATA, 0} }; I notice in DirectX 10 that it is more descriptive. Besides this, what are some of the drastic changes made, and is the HLSL syntax the same for both?

  • What web UI framework is most suitable for building dynamic pages / forms?

    - by waxwing
    Hello, We are at a stage where we are considering different Web UI frameworks (most likely component based ones such as GWT, JSF, Wicket, Vaadin, etc). One of the main use cases / constraints is that it must support generating dynamic pages. I.e., the page/form layout and components is stored in a database and is changeable at runtime, and from this pages are generated. We are also going to write static layouts, but that is not the main focus of this question. I thought maybe the user community here can share experiences of different frameworks in this context. Are there differences in ease of implementation and what is suitable?

  • Flash CS4 [AS3]: Playing Card Deck Array

    - by Ben
    I am looking to make a card game in Flash CS4 using AS3 and I am stuck on the very first step. I have created graphics for a standard 52 card deck of playing cards and imported them into the library in Flash and then proceeded to convert them all to Movie Clips. I have also used the linkage to make them available in the code. The movie clips and the linkage are named in sequence, as in the Ace of Clubs would be C1, two of Diamonds is called D2, Jack of Spades is S11. (C = Clubs, D = Diamonds, S = Spades, H = Hearts and numbers 1 through 13 are the card values. 1 being Ace, 11 being Jack, 12 being Queen, 13 being King). As far as I know my next step would be to arrange the cards into an array. This is the part that I am having problems with. Can someone please point me in the right direction, what would be the best way to do this. Could you provide me with a bit of sample code as well? I have had a look at few tutorials online but they are all telling me different things, some are incomplete and the rest...well...they're just cr*ppy. Thanks in advance! Ben

  • How popular is C++ for making websites/web applications?

    - by Vilx-
    I don't know why this is question is bugging me, but time after time I come back to the though - why not make websites in C++? So far I know of none (except a rumor about Yahoo). Most use PHP, Java or ASP.NET. Some are built on Ruby or Python, but even those are minorities. At the same time, looking at StackOverflow, it seems that C++ is still a very popular language with many projects written in it. Why not for webpages? So - what do you know about this subject? Are there any websites written in C++? Are there any framewroks/libraries that help doing this? Have YOU ever done it? If yes, did you run into any fundamental problems and would you recommend this to others?

  • rails add :prompt to form_tag fields?

    - by bob
    Hey guys, My question is simple. Can I add either of the blow :prompt => "Any" :include_blank => true to a form in form_tag. Here is an example. I would like to add :prompt to the select_tag :condition and select_tag :category fields and am having trouble. <ul id="homepage_searchbar"> <% form_tag junklists_path, :method => :get do %> <li> <%= image_tag('search_icon.png', :id => 'main_search_icon' ) %> </li> <li> <%= text_field_tag :search, "I'm looking for junk called...", :id => "main_field" %> </li> <li> <%= select_tag :condition, options_for_select(Condition.all.collect{|condition| [condition.name, condition.id]}) %> </li> <li> <%= select_tag :category, options_for_select(nested_set_options(Category) {|i| "#{'-' * i.level} #{i.name}"})%> </li> <li> <%= submit_tag "Go!", :name => 'main_submit', :id => "main_submit" %> </li> <% end %> </div> If I can't do it the way I want, how can I add a field at the top of the select boxes that has the text "Any" but has no value when the form is submitted? Thanks in advance!

  • Showing a loading spinner only if the data has not been cached.

    - by Aaron Mc Adam
    Hi guys, Currently, my code shows a loading spinner gif, returns the data and caches it. However, once the data has been cached, there is a flicker of the loading gif for a split second before the data gets loaded in. It's distracting and I'd like to get rid of it. I think I'm using the wrong method in the beforeSend function here: $.ajax({ type : "GET", cache : false, url : "book_data.php", data : { keywords : keywords, page : page }, beforeSend : function() { $('.jPag-pages li:not(.cached)').each(function (i) { $('#searchResults').html('<p id="loader">Loading...<img src="../assets/images/ajax-loader.gif" alt="Loading..." /></p>'); }); }, success : function(data) { $('.jPag-current').parent().addClass('cached'); $('#searchResults').replaceWith($(data).find('#searchResults')).find('table.sortable tbody tr:odd').addClass('odd'); detailPage(); selectForm(); } });

  • Display an Image using C# in Web Application

    - by Josh
    Hello again, I have a Web Application that I built a C# class in that generates a Report. This report takes nearly 40 seconds to generate because it searches hundreds of folders for certain files. So I was hoping there was a way to display a "Loading.." icon as this report is generating. I have a gif stored in my Images folder that would be perfect. The research that I've done at this point mostly talks about picturebox's and image controls that can hold the image but I was hoping there was just a way of displaying the image above the report while its being created. The Web Application is from a Web ADF Geocortex website and again I created a C# class that generates this report. Below is some code that may help. /// <summary> /// Generates HTML for the current report using the data in /// the given table. /// </summary> /// <param name="reportLayers">The layers to include in the report.</param> /// <returns> public override string GenerateReportHtml(List<ReportLayer> reportLayers) { StringBuilder htmlString = new StringBuilder(); StringWriter stringWriter = new StringWriter(htmlString); HtmlTextWriter writer = new HtmlTextWriter(stringWriter); string holdAPI = ""; List<string> exclusions = GetExcludedFields(); foreach (ReportLayer layer in reportLayers) { string[] strFiles = null; Boolean val = false; if (layer.Layer.Name == "Bottom Hole Location (OP)") writer.RenderBeginTag(HtmlTextWriterTag.P); // <p> writer.RenderBeginTag(HtmlTextWriterTag.Strong); // <strong> writer.Write(layer.Layer.Name); writer.RenderEndTag(); // end </strong> writer.RenderEndTag(); // end </p> writer.WriteBreak(); // <br /> foreach (ReportFeature feature in layer.ReportFeatures) { // each feature will be in a table writer.RenderBeginTag(HtmlTextWriterTag.Table); // <table> foreach (ReportField field in feature.ReportFields) { string fieldName = field.Alias; if (!exclusions.Contains(fieldName)) {

  • Practical programming test in interview

    - by redspike
    I have been invited to do a second interview for a company recruiting for a software engineer. This interview will consist of a 45 minute programmatic test on a laptop followed by a whiteboard presentation on the solution. This position is Java/J2EE based so I'm assuming (hoping) the test will be implemented using Java. Have you ever done anything like this? What was the nature of the problem you had to solve? What is a good way to prepare for this type of interview?

  • IRequiresSessionState - how do I use it?

    - by Praesagus
    I need to be able to change when I can see session state. I found out about the IRequiresSessionState Marker Interface, but have not been able to figure out how to use it. I think I may be missing something obvious. Can one of you C# guru's give me a quick 1-2-3 step through? (e.g. 1 create a new class, 2. put public interface IRequiresSessionState in it. 3. Use IRequiresSessionState('abra_cadabra') to change the value.). Thank you for your help.

  • Easy Way for Non-Nerd to Manage Simple Site?

    - by Mark Evans
    Hi I'm not sure if this is an appropriate question for StackOverflow. I have a friend show wants a simple "Brochure Ware" web site. I could make it for him but it would be better if he could manage it himself. Are there any services out there that allow a non-technical person to create and maintain a very simple site? I'm thinking just a few pages - contact, about, home with some photos and general info. He also wants to sell some stuff but I'm going to suggest he does this using EBay but the web site would be a handy reference for potential customers who want to know more about him and his services. Thanks a lot! Cheers Mark

  • web developer editor ubuntu

    - by madphp
    Hi, I know theres hundred of questions and answers out there, but cant find one to specifically answer this. I need a web editor that will let me choose a dark themed editor. I understand gvim is one, but im not totally ready to let go of my mouse. I would like something like sublime text editor for windows, but open to other suggestions. The less bloat the best. I dont need a full IDE like eclipse, but willing to compromise, as long as the themes can easily be added. I've tried bluefish, kompozer and not happy with them. Just need a basic text editor that will highlight php syntax on a dark background.

  • Do you feel threatened by younger developers?

    - by bobsmith123
    When an opportunity for a new project in my company presented itself, I volunteered with a little bit of skepticism but a lot of excitement. I have been working with this company for 5 years on a different project in which I was a team lead for several releases. I have a consistent track record of delivering good quality projects. The new project has a team that is built from ground up and the management decided to hire new developers. The technologies used are the latest ones that are different from the previous project I had worked on (although they both are in .NET). The newer and the younger developers in the team have more experience with the latest technologies from their previous gigs. The younger developers have a lot more energy, can work 14 hours a day (they remind me of my early 20s) and live on ramen noodles. Since they are new, I feel they are obligated to show what they are made of and to prove their mettle. I feel like I am sidelined in this project and the management obviously like the younger developers as they bring more to the table. I know ageism is rampant in our field and the more I think about this, the more it makes me feel that there are very few transferable skills from one project to the other and one day you could be a team lead managing a number of developers, the next day some one you hired becomes your boss. Do you see yourself in situations like this very often? What plans do you have to make yourself valuable in a long term perspective?

  • SetCursor reverts after a mouse move

    - by Joe Ludwig
    I am using SetCursor to set the system cursor to my own image. The code looks something like this: // member on some class HCURSOR _cursor; // at init time _cursor = LoadCursorFromFile("somefilename.cur"); // in some function SetCursor(_cursor); When I do this the cursor does change, but on the first mouse move message it changes back to the default system arrow cursor. This is the only code in the project that is setting the cursor. What do I need to do to make the cursor stay the way I set it?

  • PHP: How should I move my code from dev to production?

    - by Teddy
    I have created a PHP web-application. I have 3 environments: DEV, TEST, PROD. What's a good tool / business practice for me to move my PHP web-application code from DEV to TEST to the PROD environment? Realizing that my TEST environment still only connects to my TEST database; whereas, I need to PROD environment to connect to my PROD database. So the code is mostly the same, except that I need to change my TEST code once moved into PROD to connect to the PROD database and not TEST database. I've heard of people taking down Apache in such away that it doesn't allow new connections and once all the existing connections are idle it simply brings down the web server. Then people manually copy the code and then manually update the config files of the PHP application to also point to the PROD instance. That seems terribly dangerous. Does a best practice exists?

    - by Michiel de Mare
    Form Based Authentication For Websites Please help us create the definitive resource for this topic. We believe that stackoverflow should not just be a resource for very specific technical questions, but also for general guidelines on how to solve variations on common problems. "Form Based Authentication For Websites" should be a fine topic for such an experiment. It should include topics such as: how to log in how to remain logged in how to store passwords using secret questions forgotten password functionality OpenID "Remember me" checkbox Browser autocompletion of usernames and passwords secret urls (public urls protected by digest) checking password strength email validation and much more It should not include things like: roles and authorization http basic authentication Please help us by Suggesting subtopics Submitting good articles about this subject Editing the official answer (as soon as you have enough karma) UPDATE: See the terrific 7-part series by Jens Roland below.
