  • Computer Quiz Management Software

    - by Asad Jibran Ahmed
    My university is holding a quiz contest in 2 weeks, and I need some sort of software (desktop or web based) that can be used to manage the quiz. I need functionality like an admin panel for adding teams, creating matches between 2 teams, adding questions and answers. I then need the software to automatically display the questions, accept answers, and display and store results. Is there any software (open source/freeware) that I can use for this task. If a pre-built software is not available, which language+library+platform would you suggest I make the software in. It can be either web based or a desktop app. But I need it by 2 weeks. Any suggestions?

  • Authentication Problem - not recognizing 'else' - Ruby on rails...

    - by bgadoci
    I can't seem to figure out what I am doing wrong here. I have implemented the Super Simple Authentication from Ryan Bates tutorial and while the login portion is functioning correctly, I can't get an error message and redirect to happen correctly for a bad login. Ryan Bates admits in his comments he left this out but can't seem to implement his recommendation. Basically what is happening is that when someone logs in correctly it works. When a bad password is entered it does the same redirect and flashes 'successfully logged in' thought they are not. The admin links do not show (which is correct and are the links protected by the <% if admin? %) but I need it to say 'failed login' and redirect to login path. Here is my code: SessionsController class SessionsController < ApplicationController def create if session[:password] = params[:password] flash[:notice] = 'Successfully logged in' redirect_to posts_path else flash[:notice] = "whoops" redirect_to login_path end end def destroy reset_session flash[:notice] = 'Successfully logged out' redirect_to posts_path end end ApplicationController class ApplicationController < ActionController::Base helper_method :admin? protected def authorize unless admin? flash[:error] = "unauthorized request" redirect_to posts_path false end end def admin? session[:password] == "123456" end helper :all # include all helpers, all the time protect_from_forgery # See ActionController::RequestForgeryProtection for details # end

  • Comparisons of web programming languages (on speed, etc.)

    - by Dave
    I'm looking for a site / report / something that can compares "identical" programs (programs that do the same thing) in different web-programming languages and then compares the speeds of each of them. I agree that there will be MANY MANY criteria on which this information can be sliced and diced by, but has anyone done any real comparison of this? I am interested in web-based languages only, ie php, perl, C, C++, java, asp, asp.net, etc.

  • Software-related but not programming-specific questions

    - by jayrdub
    I have often fought the urge to ask questions that I know aren't appropriate on SO, because I personally haven't come across another online group who's opinions I would trust as much. What sites do you frequent that you have found good participation from a smart group of people where you can ask questions that are related to software, but not programming problems? This community also has a vast depth of knowledge about things related to software like marketing, graphics/UI, running a small business, working in bad jobs, etc. that would greatly benefit everyone else. Where do we go to tap all that knowledge? On stackoverflow.uservoice.com there is a popular suggested feature to sanction, or add to SO, a place to hold discussions that aren't about specific programming questions. It seems that the suggestion has been denied in the past though.

  • Truncated string in android spinners

    - by DrogoNevets
    On the iPhone, if an option is too long for the area, instead of wrappeing you get a "..." at the end of the "drop down" and the user will know there is more text than is shown. I want to recreate this with android but am new to it so cant see how. I want the heights of "rows" in my layout to be uniform hence not able to wrap the text. Thanks in advance.

  • WAMP Server not working

    - by Jeremy Rudd
    Okay so a continuation from this question, where you experts intro'd me to WAMP, which can basically execute PHP within a Windows XP environment. So now I've got it installed, but the tray icon forever shows YELLOW, and when I visit any PHP page in my browser, it just shows me the PHP source! Also, when I visit "http://localhost/" in IE7 it gives me a 404 Not Found, FF3 just shows a blank page. BTW I've tried "Restart All Services" and restarting my machine, but it still won't work. Any ideas? Any of you had this problem and solved it? Please help me here, I'm desperate to execute PHP client-side and I'm just reverting to testing on-server for now!

  • Autocomplete Error Question - Ruby on Rails

    - by bgadoci
    I have built a very simple blog application using Ruby on Rails. New to both Ruby and Rails so excuse the stupid questions. I currently have two tables that relate to this question. I have a Post table and a Tag table. Basically I set it up such that Post has_many :tags and Tag belongs_to :post. I am using AJAX to process and display the tags in the show view of the post. I installed the auto_complete plugin and I am getting an error when I enter the letters in the text_field_with_auto_complete for tag creation. My suspicion is this is because the form is a remote_form_for or something I am doing wrong in the routes.rb. Here is the error and code: Error Processing PostsController#show (for 127.0.0.1 at 2010-04-13 23:25:46) [GET] Parameters: {"tag"=>{"tag_name"=>"f"}, "id"=>"auto_complete_for_tag_tag_name"} Post Load (0.1ms) SELECT * FROM "posts" WHERE ("posts"."id" = 0) ActiveRecord::RecordNotFound (Couldn't find Post with ID=auto_complete_for_tag_tag_name): app/controllers/posts_controller.rb:22:in `show' Rendered rescues/_trace (26.0ms) Rendered rescues/_request_and_response (0.2ms) Rendering rescues/layout (not_found) remote_form_for located in /views/posts/show.html.erb <% remote_form_for [@post, Tag.new] do |f| %> <p> <%= f.label :tag_name, "Tag" %><br/> <%= text_field_with_auto_complete :tag, :tag_name, {}, {:method => :get} %> </p> <p><%= f.submit "Add Comment" %></p> <% end %> tags_controller.rb (I'll spare you all the actions but added the following here) auto_complete_for :tag, :tag_name routes.rb map.resources :posts, :has_many => :comments map.resources :posts, :has_many => :tags map.resources :tags, :collection => {:auto_complete_for_tag_tag_name => :get }

  • how to place last div into right top corner of partent div? (css)

    - by Radek
    can I somehow using css place the block2 in right top corner of block1? Note that block2 must be the (very) last inside html code of block1 or it could be placed after block1. I cannot make it the first element in block1 <html> <head> <style type="text/css"> .block1 {color:red;width:100px;border:1px solid green;} .block2 {color:blue;width:70px;border:2px solid black;position:relative;} </style> </head> <body> <div class='block1'> <p>text</p> <p>text2</p> <div class='block2'>block2</DIV> </div> </body> </html>

  • Problem exporting RSA key -'key not valid for use in specified state'

    - by asp316
    I'm encrypting the web.config in our web sites using aspnet_regiis. However, I want the ability to export the encryption key so if we need to move from Machine A to Machine B, asp.net will be able to decrypt it. When I run aspnetregiis -px "NetFrameworkConfigurationKey" c:\keys.xml -pri, I get the following : 'Key not valid for use in specified state'. I've seen all kinds of responses online but they don't seem to apply. It's not an invalid key because when I use aspnet_regiis to encrypt sections of the web.config, they encrypt fine. Ideas?

  • OpenSteer on Xbox 360?

    - by Rosarch
    I want to use OpenSteer for my game that I want to be compatible with the Xbox 360. I have heard that since it is a wrapper for a C++ library, it will work in XNA on a PC, but not on the Xbox. Is there no way to make it compatible?

  • How should a QA Environment be setup?

    - by onesith
    I am currently at a loss. We are moving from Dev-owned testing environment to a QA-owned one. I have worked in a QA-owned testing environment before. But I have never set one up from scratch. I understand that it should mirror Production as much as possible. But how? How have you setup your QA Environment?

  • Form values in a list item

    - by Tri
    Here is the site mock-up I'm working on for my job: http://dev.arm.gov/~noensie/dqhands/cgi-bin/explorer. I'm still a novice in web developing and I need help with placing form values in a list item to pass on to another page. I'd rather not go in great detail the purpose of this website, but in terms of its basic use, select the parameters in the middle column for a request and add it to the list on the right column by pressing on "add request" button when it appears. After the list have been populated, a user would submit the selected requests, which will direct them to another page based on the requests selected (or added to the list, same thing). That last sentence is where I'm having a problem. Right now, each of request in the list in the right column are <li> elements and I assign them attribute values that needed to be passed on to the next page. I tried inserting a hidden input with same values, but I'm still not sure how to utilize that; I'm not even sure using the hidden input is the correct way. Also the "submit request" button is located outside the <form> block. I was going to utilize javascript and jQuery to enable the button to serialize the values in the <form> block, but I don't know quite how to do that. Go ahead and take a look at my javascript code (index.js) and slay me, or, I mean, my code. It's still pretty elementary and short (~260 lines, that's short right?). I will take any help for this problem (as the matter of fact, if you see any other problems or a better way of implementation of something, go ahead and mention that too); tips, advice, code samples, or whatever else you can contribute, it will be greatly appreciated.

  • Need help with implementing collision detection using the Separating Axis Theorem

    - by Eddie Ringle
    So, after hours of Googling and reading, I've found that the basic process of detecting a collision using SAT is: for each edge of poly A project A and B onto the normal for this edge if intervals do not overlap, return false end for for each edge of poly B project A and B onto the normal for this edge if intervals do not overlap, return false end for However, as many ways as I try to implement this in code, I just cannot get it to detect the collision. My current code is as follows: for (unsigned int i = 0; i < asteroids.size(); i++) { if (asteroids.valid(i)) { asteroids[i]->Update(); // Player-Asteroid collision detection bool collision = true; SDL_Rect asteroidBox = asteroids[i]->boundingBox; // Bullet-Asteroid collision detection for (unsigned int j = 0; j < player.bullets.size(); j++) { if (player.bullets.valid(j)) { Bullet b = player.bullets[j]; collision = true; if (b.x + (b.w / 2.0f) < asteroidBox.x - (asteroidBox.w / 2.0f)) collision = false; if (b.x - (b.w / 2.0f) > asteroidBox.x + (asteroidBox.w / 2.0f)) collision = false; if (b.y - (b.h / 2.0f) > asteroidBox.y + (asteroidBox.h / 2.0f)) collision = false; if (b.y + (b.h / 2.0f) < asteroidBox.y - (asteroidBox.h / 2.0f)) collision = false; if (collision) { bool realCollision = false; float min1, max1, min2, max2; // Create a list of vertices for the bullet CrissCross::Data::LList<Vector2D *> bullVerts; bullVerts.insert(new Vector2D(b.x - b.w / 2.0f, b.y + b.h / 2.0f)); bullVerts.insert(new Vector2D(b.x - b.w / 2.0f, b.y - b.h / 2.0f)); bullVerts.insert(new Vector2D(b.x + b.w / 2.0f, b.y - b.h / 2.0f)); bullVerts.insert(new Vector2D(b.x + b.w / 2.0f, b.y + b.h / 2.0f)); // Create a list of vectors of the edges of the bullet and the asteroid CrissCross::Data::LList<Vector2D *> bullEdges; CrissCross::Data::LList<Vector2D *> asteroidEdges; for (int k = 0; k < 4; k++) { int n = (k == 3) ? 0 : k + 1; bullEdges.insert(new Vector2D(bullVerts[k]->x - bullVerts[n]->x, bullVerts[k]->y - bullVerts[n]->y)); asteroidEdges.insert(new Vector2D(asteroids[i]->vertices[k]->x - asteroids[i]->vertices[n]->x, asteroids[i]->vertices[k]->y - asteroids[i]->vertices[n]->y)); } for (unsigned int k = 0; k < asteroidEdges.size(); k++) { Vector2D *axis = asteroidEdges[k]->getPerpendicular(); min1 = max1 = axis->dotProduct(asteroids[i]->vertices[0]); for (unsigned int l = 1; l < asteroids[i]->vertices.size(); l++) { float test = axis->dotProduct(asteroids[i]->vertices[l]); min1 = (test < min1) ? test : min1; max1 = (test > max1) ? test : max1; } min2 = max2 = axis->dotProduct(bullVerts[0]); for (unsigned int l = 1; l < bullVerts.size(); l++) { float test = axis->dotProduct(bullVerts[l]); min2 = (test < min2) ? test : min2; max2 = (test > max2) ? test : max2; } delete axis; axis = NULL; if ( (min1 - max2) > 0 || (min2 - max1) > 0 ) { realCollision = false; break; } else { realCollision = true; } } if (realCollision == false) { for (unsigned int k = 0; k < bullEdges.size(); k++) { Vector2D *axis = bullEdges[k]->getPerpendicular(); min1 = max1 = axis->dotProduct(asteroids[i]->vertices[0]); for (unsigned int l = 1; l < asteroids[i]->vertices.size(); l++) { float test = axis->dotProduct(asteroids[i]->vertices[l]); min1 = (test < min1) ? test : min1; max1 = (test > max1) ? test : max1; } min2 = max2 = axis->dotProduct(bullVerts[0]); for (unsigned int l = 1; l < bullVerts.size(); l++) { float test = axis->dotProduct(bullVerts[l]); min2 = (test < min2) ? test : min2; max2 = (test > max2) ? test : max2; } delete axis; axis = NULL; if ( (min1 - max2) > 0 || (min2 - max1) > 0 ) { realCollision = false; break; } else { realCollision = true; } } } if (realCollision) { player.bullets.remove(j); int numAsteroids; float newDegree; srand ( j + asteroidBox.x ); if ( asteroids[i]->degree == 90.0f ) { if ( rand() % 2 == 1 ) { numAsteroids = 3; newDegree = 30.0f; } else { numAsteroids = 2; newDegree = 45.0f; } for ( int k = 0; k < numAsteroids; k++) asteroids.insert(new Asteroid(asteroidBox.x + (10 * k), asteroidBox.y + (10 * k), newDegree)); } delete asteroids[i]; asteroids.remove(i); } while (bullVerts.size()) { delete bullVerts[0]; bullVerts.remove(0); } while (bullEdges.size()) { delete bullEdges[0]; bullEdges.remove(0); } while (asteroidEdges.size()) { delete asteroidEdges[0]; asteroidEdges.remove(0); } } } } } } bullEdges is a list of vectors of the edges of a bullet, asteroidEdges is similar, and bullVerts and asteroids[i].vertices are, obviously, lists of vectors of each vertex for the respective bullet or asteroid. Honestly, I'm not looking for code corrections, just a fresh set of eyes.

  • Deploying only changed part of a website with git to ftp (svn2web for git)

    - by Elazar Leibovich
    I'm having a website with many big images file. The source (as well as the images) is maintained with git. I wish to deploy that via ftp to a bluehost-like cheap server. I do not wish to deploy all the website each time (so that I won't have to upload too many unchanged files over and over), but to do roughly the following: In a git repository, mark the last deployed revision with a tag "deployed". When I say "deploy revision X", find out which files has changed between revision X and revision tagged as deploy, and upload just them. It is similar in spirit to svn2web. But I want that for DVCS. Mercurial alternative will be considered. It's a pretty simple script to write, but I'd rather not to reinvent the wheel if there's some similar script on the web. Capistrano and fab seems to know only how to push the whole revision, in their SCM integration. So I don't think I can currently use them.

  • CSS rule ignored in IE8 Quirks Mode.

    - by ProfK
    I have a ul/li based side menu, styled with two CSS rules, the following of them is ignored by IE8 Quirks mode, and I assume IE6: ul { padding-left: 15px; } I can reproduce the problem in FF by removing this rule completely. I have also tried using jQuery to apply the rule, with no change in IE8: $("ul.menu-class").find("ul").css("padding-left", 15); Is this a box model issue, and, how can I reduce the UL 'padding' in IE Quirks Mode?

  • Jquery Cluetip - clean up between ajax loaded content

    - by ted776
    Hi, I'm using the jquery cluetip plugin and trying to figure out how to remove any open cluetip dialogs once i load new content via ajax. I am either stuck with the dialog boxes still showing on top of new content, or the ways i've tried to fix this actually remove all future cluetip dialogs from showing at all. Here's my code, thanks for any help. On dom ready i instantiate cluetip as below. //activate cluetip $('a.jTip').cluetip({ attribute: 'href', cluetipClass: 'jtip', arrows: true, activation: 'click', ajaxCache: false, dropShadow: true, sticky: true, mouseOutClose: false, closePosition: 'title' }); When i'm loading new content, I have the following code. The problem i have is that $('.cluetip-jtip').empty() prevents dialog boxes from opening on any of the new content loaded in, while the destroy function doesn't remove any open dialog boxes, but just destroys the current object. $('.next a').live("click", function(){ var toLoad = $(this).attr('href'); var $data = $('#main_body #content'); $.validationEngine.closePrompt('body'); //close any validation messages $data.fadeOut('fast', function(){ $data.load(toLoad, function(){ $data.animate({ opacity: 'show' }, 'fast'); //reinitialise datepicker and toolip $(".date").date_input(); //JT_init(); $('.hidden').hide(); //scroll to top of form $("html,body").animate({ "scrollTop": $('#content').offset().top + "px" }); //remove existing instance //$('a.jTip').cluetip('destroy'); //remove any opened popups $('.cluetip-jtip').empty(); //reinitialise cluetip $('a.jTip').cluetip({ attribute: 'href', cluetipClass: 'jtip', arrows: true, activation: 'click', ajaxCache: false, dropShadow: true, sticky: true, mouseOutClose: false, closePosition: 'title' }); }); }); return false; });
