28,422,403 | 0 | <p>In apps with user sessions, it is usually best to keep login/signup on a separate view hierarchy from the rest of the app and present the internal structure if there is an active session. You can achieve this by checking for</p> <pre><code>[PFUser currentUser] </code></pre> <p>as it will return <code>nil</code> if the user is not logged in.</p> <p><strong>Provide a check in your AppDelegate like so:</strong></p> <pre><code>- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { // ..

7,901,430 | 0 | How to execute multiple async calls in parallel? <p>I have a number of commands that make calls to a soap web service (Betfair API). All are of the classic asynchronous programming model type ...</p> <pre><code>public void DoXXX( <input parameters ...> ) { XXXRequest Request = new XXXRequest(); // populate Request from input parameters ... BetfairService.BeginXXX( Request, XXXCallback, State ); } private void XXXCallback(IAsyncResult Result) { XXXResponse Response = BetfairService.EndXXX(Result); if (Response.ErrorCode == XXXErrorCode.OK) // store data from Response else // deal with error } </code></pre> <p>I want to execute a specified set of commands, and then do some calculations using the combined returned data values, once all of commands are completed.</p> <p>I'm able to do this as a sequence, by making a queue of commands and having each callback method trigger the next command in the queue once it's complete, with the calculation as the last item in the queue. This is relatively slow however.</p> <p>My ideal solution would be to have all of these commands running in parallel and then to have the calculation triggered once all of the commands are completed. I've tried looking at Task.Factory.FromAsync(), but all of the examples I can find only include direct calls to BeginXXX / EndXXX, not doing anything with the response.</p> <p>Does anyone have any pointers for a suitable solution to this problem?</p> |

13,694,421 | 0 | Resize tumblr videos <p>I have created a tumblr theme. Everything was working till I decided to post a video on tumblr video upload. I have a box on main page 250x196 pixels where everything goes in. </p> <ul> <li>If it is a photo, I just make it 250x196 pixels (I don't care about aspect ratio. I've used jQuery to keep aspect ratio but I didn't like the result).</li> <li>If it's a photoset I use anythingslider and create a slide.</li> <li>If it's a text post I use jquery and take the first image as a tumbnail.</li> <li>If it's a video the same as photos. I just resize the iframe. At least that's what I thought I was doing.</li> </ul> <p><em>I also use prettyphoto as a lightbox clone for both images and videos.</em></p> <p>So when I used tumblr upload video, I had these problems: </p> <ol> <li>First the video didn't get the aspect ratio of the iframe i think the reason for that might be the data values for height and with the iframe is using.</li> <li>As you can see <a href="http://www.no-margin-for-errors.com/projects/prettyphoto-jquery-lightbox-clone/" rel="nofollow"><strong>here</strong></a>; for the iframe to appear, I was using the inline method. I had a hidden div which had the 500pixels version of the video. The problem is that {Video-250} and {Video-500} tumblr variables both create a div for the tumblr videos with the same id. So it takes the hidden video and moves it next to the 250 pixels version.</li> <li>The build in lightbox of tumblr for videos had a conflict with prettyphoto. When I was clicking the full screen of the video something was wrong with the z-indexes. I didn't spend time on solving this issue because I already had so many problems.</li> </ol> <p>As a workaround, What I did was this: </p> <pre><code> <div class="media" data-embed="{JSVideoEmbed-250}" data-video="{JSVideo-250}"></div> </code></pre> <p>You can see exactly what I mean on a test blog i create with three random videos:</p> <p><a href="http://stroumfaki.tumblr.com/" rel="nofollow">http://stroumfaki.tumblr.com/</a></p> <p>But the problem with the resizing still remains. The iframe is 250x196 pixels but the contents aren't. I also don't understand why tumblr posts a javascript in the first only video. The same script it posts at the end of the page. </p> <p>What I ask might be a bit hard to articulate. I hope the test blog will help you understand what I mean.</p> |

12,006,393 | 0 | <p>From the "Core Data Programming Guide":</p> <blockquote> <p>... To summarize, though, if you execute a fetch directly, you should typically not add Objective-C-based predicates or sort descriptors to the fetch request.

Derrick is suggesting that <em>after</em> the dropdownlist is bound, then go through and disable the separators. So it would look something more like this:</p> <pre><code>protected void gvCategory_DataBound(object sender, EventArgs e) { foreach (ListItem li in gvCategory.Items) { if(li.Text.Contains("--")) li.Attributes.Add("disabled", "true"); } } </code></pre> <p><strong>Update 2:</strong></p> <p>Add the OnDataBound event to manipulate the DropDownList after it is bound.</p> <pre><code><asp:DropDownList ID="gvCategory" runat="server" OnDataBound="gvCategory_DataBound"></asp:DropDownList> </code></pre> |

18,683,079 | 0 | <p>The regular CursorLoader is based on Android's ContentProvider - so if you're not using it, you'll have to write your own Loader. Here's one way you can do it:</p> <p><a href="https://github.com/commonsguy/cwac-loaderex/blob/master/src/com/commonsware/cwac/loaderex/acl/AbstractCursorLoader.java" rel="nofollow">https://github.com/commonsguy/cwac-loaderex/blob/master/src/com/commonsware/cwac/loaderex/acl/AbstractCursorLoader.java</a></p> <p>From that point it's pretty straight forward. Your activity/fragment can be a callback for the LoaderManager - it will need to implement LoaderCallbacks interface. </p> <p>Instead of running your query, use getLoaderManager().initLoader(this, null, LOADER_ID) to initialize data loading. Here's an example: <a href="http://developer.android.com/reference/android/app/LoaderManager.html" rel="nofollow">http://developer.android.com/reference/android/app/LoaderManager.html</a></p> <p>Now, the data will be in the onLoadFinished() callback. If you did everything right, you'll get your cursor here. Now simply use the cursor to populate your list. </p> |

This helps eliminate a specific problem with your files, like a wonky DRM scheme that only permits playback on an approved player.</li> <li>Make sure you run this code on an STA thread, the kind provided by a Winforms or WPF app. <em>Not</em> a console mode app, it requires the kind of code you find in <a href="http://stackoverflow.com/a/21684059/17034">this post</a>.</li> <li>Beware of having non-standard ACM drivers installed.

In Matlab:</p> <pre><code>dist = sqrt(sum((a-b).^2)); </code></pre> <p>However, you might want to use <a href="http://www.mathworks.nl/help/toolbox/stats/pdist.html" rel="nofollow"><code>pdist</code></a> to compute it for all combinations of vectors in your matrix at once.</p> <pre><code>dist = squareform(pdist(myVectors, 'euclidean')); </code></pre> <p>I'm interpreting columns as instances to classify and rows as potential neighbors. This is arbitrary though and you could switch them around.</p> <p>If have a separate test set, you can compute the distance to the instances in the training set with <code>pdist2</code>:</p> <pre><code>dist = pdist2(trainingSet, testSet, 'euclidean') </code></pre> <p>You can use this distance matrix to knn-classify your vectors as follows. I'll generate some random data to serve as example, which will result in low (around chance level) accuracy. But of course you should plug in your actual data and results will probably be better.</p> <pre><code>m = rand(nrOfVectors,nrOfFeatures); % random example data classes = randi(nrOfClasses, 1, nrOfVectors); % random true classes k = 3; % number of neighbors to consider, 3 is a common value d = squareform(pdist(m, 'euclidean')); % distance matrix [neighborvals, neighborindex] = sort(d,1); % get sorted distances </code></pre> <p>Take a look at the <code>neighborvals</code> and <code>neighborindex</code> matrices and see if they make sense to you. The first is a sorted version of the earlier <code>d</code> matrix, and the latter gives the corresponding instance numbers. Note that the self-distances (on the diagonal in <code>d</code>) have floated to the top. We're not interested in this (always zero), so we'll skip the top row in the next step.</p> <pre><code>assignedClasses = mode(neighborclasses(2:1+k,:),1); </code></pre> <p>So we assign the most common class among the k nearest neighbors!</p> <p>You can compare the assigned classes with the actual classes to get an accuracy score:</p> <pre><code>accuracy = 100 * sum(classes == assignedClasses)/length(classes); fprintf('KNN Classifier Accuracy: %.2f%%\n', 100*accuracy) </code></pre> <p>Or make a confusion matrix to see the distribution of classifications:</p> <pre><code>confusionmat(classes, assignedClasses) </code></pre> |

An activation function f. Many different functions can take place with the identity function being the simplest. </p> <p>The neuron output Y, is the result of applying the <strong>activation function</strong> to the <strong>weighted sum</strong> of the <strong>inputs</strong>, less the <strong>threshold</strong>. </p> <p>This value can be discrete or real depending on the activation function used.</p> <p><a href="https://i.stack.imgur.com/4hHb5.png" rel="nofollow noreferrer">Here's</a> an output of Y that holds a specific function F.</p> <p>Once the output has been calculated, it can be passed to another neuron (or group of neurons) or sampled by the external environment. The interpretation of the neuron output depends upon the problem under consideration</p> <p>@Seephore</p> <p>In principle, there is no limit on the number of hidden layers that can be used in an artificial neural network. Such networks can be trained using "stacking" or other techniques from the deep learning literature. Yes, you could have 1000 layers, though I don't know if you'd get much benefit: in deep learning I've more typically seen somewhere between 1-20 hidden layers, rather than 1000 hidden layers. In practice the number of layers is based upon pragmatic concerns, e.g., what will lead to good accuracy with reasonable training time and without overfitting.</p> <p><strong>What you're asking:</strong> Im going to assume you meant to say 100 input and 1000 output?

565,460 | 0 | <p>You sound as though you are "rolling your own" authentication system.</p> <p>I would look into using ASP.NET's built in <a href="http://msdn.microsoft.com/en-us/library/xdt4thhy.aspx" rel="nofollow noreferrer">Forms authentication</a> system that is commonly used with an ASP.NET <a href="http://msdn.microsoft.com/en-us/library/aa478949.aspx" rel="nofollow noreferrer">Membership Provider</a>. Built-in providers already exist for SQL Server, and you can create your own Membership Provider by inheriting from the <a href="http://msdn.microsoft.com/en-us/library/system.web.security.membershipprovider.aspx" rel="nofollow noreferrer">System.Web.Security.MembershipProvider</a> base class.</p> <p>Essentially, the ASP.NET membership providers usually work by setting a client side cookie (also known as an Authentication Ticket) in the client's browser, once the client has successfully authenticated themselves. This cookie is returned to the web server with each subsequent page request, allowing ASP.NET, and thus your code, to determine who the user is, usually with a single line of code like so:</p> <pre><code>string username = HttpContext.Current.User.Identity.Name; // The above gets the current user's name. if(HttpContext.Current.User.Identity.IsAuthenticated) // Do something when we know the user is authenticated. </code></pre> <p>You then should not need to store anything in the Session state. Of course, if you <em>want</em> to store user-specific data in a session variable (i.e. user-data that may not be part of the authentication of a user, perhaps the user's favourite colour etc.) then by all means you can store that in a session variable (after retrieving it from the DB when the user is first authenticated). The session variable could be stored based on the user's name (assuming unique names) and retrieved using code similar to the above which gets the current user's name to access the correct session object.</p> <p>Using the built-in forms authentication will also allow you to "protect" areas of your website from un-authorized users with simple declarative code that goes in your web.config, for example:</p> <pre><code><authorization> <deny users="?"/> </authorization> </code></pre> <p>Adding the above to your "main" web.config would ensure that none of your pages are accessible to un-authorized users (though you'd probably never do this in reality - it's just meant as an example). Using the ASP.NET <a href="http://msdn.microsoft.com/en-us/library/aa479032.aspx" rel="nofollow noreferrer">Role Provider</a> in conjunction with the Membership Provider will give you even greater granularity over who can or can't access various sections of your website.</p> |
