identity

I am developing a video streaming website. I want to count unique views on each video. I referred to some sites on internet and even asked some other programmers. They say either use cookies or session or IP address. But these things changes over time. Also if possible can we do this using MAC address of the user's machine? Also I came across a similar question here -> http://bit.ly/Qh1KNR . They say there is something like browser fingerprint that uses MAC address. So can you tell me what method is the best one? You can use Evercookie concept which stores cookie data on different storage

under Identity Inspector as we all know that the label property is used to identify objects easier in interface builder, but what are the colors to the bottom of it used for ? I tried to select a color but nothing changed in interface builder. EDIT: screenshot: If you don't already use color labels to sort your files and folders, then you really should consider it. Using color labels allows you to enhance your file organization by assigning certain colors to certain files. You can assign color labels to files by doing a "Get Info" (highlight the file, then press command + i) on the file/folder

Possible Duplicate: php == vs === operator i have the following code fragment and it doesn't make sense to me why would NULL be evaluated in 3 different ways. Consider the variable $uploaded_filenames_array as UNKNOWN - we don't know whether it's still an array or a NULL. That's what we are trying to check. //----------------------------------------------- if (is_null($uploaded_filenames_array)){ echo "is_null"; } else{ echo "is_NOT_null"; } //----------------------------------------------- if ($uploaded_filenames_array == NULL){ echo "NULL stuff"; } else{ echo "not NULL stuff"; } //----------

private IAuthenticationManager AuthenticationManager { get { return HttpContext.GetOwinContext().Authentication; } } I get the error : 'System.Web.HttpContextBase' does not contain a definition for 'GetOwinContext' and no extension method 'GetOwinContext' accepting a first argument of type 'System.Web.HttpContextBase' could be found (are you missing a using directive or an assembly reference?) What might be wrong? It seems you have missing NuGet package called 'Microsoft.Owin.Host.SystemWeb'. Install package from NuGet or use package manager console to install the package. Install-Package

On my website I have a header defined in my _Layout.cshtml. In that file, I'm doing this: <li class="dropdown"> @if (Request.IsAuthenticated) { <a href="#" class="dropdown-toggle menuItem" data-toggle="dropdown" style="color: red;">@User.Identity.Name <b class="caret"></b></a> } else { <a href="#" class="dropdown-toggle menuItem" data-toggle="dropdown">Profile <b class="caret"></b></a> } <ul class="dropdown-menu"> @if (!Request.IsAuthenticated) { <li><a href="/Account/Register">Register</a></li> <li><a href="/Account/Login">Login</a></li> <li><a href="/Account/ForgotPassword">Forgot Password<
