Access Parent URL From Iframe

Answer : Yes, accessing parent page's URL is not allowed if the iframe and the main page are not in the same (sub)domain. However, if you just need the URL of the main page (i.e. the browser URL), you can try this: var url = (window.location != window.parent.location) ? document.referrer : document.location.href; Note: window.parent.location is allowed; it avoids the security error in the OP, which is caused by accessing the href property: window.parent.location.href causes "Blocked a frame with origin..." document.referrer refers to "the URI of the page that linked to this page." This may not return the containing document if some other source is what determined the iframe location, for example: Container iframe @ Domain 1 Sends child iframe to Domain 2 But in the child iframe... Domain 2 redirects to Domain 3 (i.e. for authentication, maybe SAML), and then Domain 3 directs back to Domain 2 (i.e. via form submissi

Can I Install The "app Store" In An IOS Simulator?

Answer : This is NOT possible The Simulator does not run ARM code, ONLY x86 code. Unless you have the raw source code from Apple, you won't see the App Store on the Simulator. The app you write you will be able to test in the Simulator by running it directly from Xcode even if you don't have a developer account. To test your app on an actual device, you will need to be apart of the Apple Developer program. No, according to Apple here: Note: You cannot install apps from the App Store in simulation environments. You can install other builds but not Appstore build. From Xcode 8.2 ,drag and drop the build to simulator for the installation. https://stackoverflow.com/a/41671233/1522584

Convert StdClass Object To Array In PHP

Answer : The easiest way is to JSON-encode your object and then decode it back to an array: $array = json_decode(json_encode($object), true); Or if you prefer, you can traverse the object manually, too: foreach ($object as $value) $array[] = $value->post_id; Very simple, first turn your object into a json object, this will return a string of your object into a JSON representative. Take that result and decode with an extra parameter of true, where it will convert to associative array $array = json_decode(json_encode($oObject),true); Try this: $new_array = objectToArray($yourObject); function objectToArray($d) { if (is_object($d)) { // Gets the properties of the given object // with get_object_vars function $d = get_object_vars($d); } if (is_array($d)) { /* * Return array converted to object * Using __FUNCTION__ (Magic constant) * for recursive call */ return array_map(__FUNCTION__, $d); } e

Cross Validation For MNIST Dataset With Pytorch And Sklearn

Image
Answer : I think you're confused! Ignore the second dimension for a while, When you've 45000 points, and you use 10 fold cross-validation, what's the size of each fold? 45000/10 i.e. 4500. It means that each of your fold will contain 4500 data points, and one of those fold will be used for testing, and the remaining for training i.e. For testing: one fold => 4500 data points => size: 4500 For training: remaining folds => 45000-4500 data points => size: 45000-4500=40500 Thus, for first iteration, the first 4500 data points (corresponding to indices) will be used for testing and the rest for training. (Check below image) Given your data is x_train: torch.Size([45000, 784]) and y_train: torch.Size([45000]) , this is how your code should look like: for train_index, test_index in kfold.split(x_train, y_train): print(train_index, test_index) x_train_fold = x_train[train_index] y_train_fold = y_train[train_index] x_test_fold = x_train[test_i

Creating An Oracle User If It Doesn't Already Exist

Answer : The IF NOT EXISTS syntax available in SQL Server, is not available in Oracle. In general, Oracle scripts simply execute the CREATE statement, and if the object already exist, you'll get an error indicating that, which you can ignore. This is what all the standard Oracle deployment scripts do. However, if you really want to check for existence, and only execute if object doesn't exist, thereby avoiding the error, you can code a PL/SQL block. Write a SQL that checks for user existence, and if it doesn't exist, use EXECUTE IMMEDIATE to do CREATE USER from the PL/SQL block. An example of such a PL/SQL block might be: declare userexist integer; begin select count(*) into userexist from dba_users where username='SMITH'; if (userexist = 0) then execute immediate 'create user smith identified by smith'; end if; end; / You need to write a pl/sql block. See an example here You can check if the user exists in the all_users table using som

Copy File From Source Directory To Binary Directory Using CMake

Answer : You may consider using configure_file with the COPYONLY option: configure_file(<input> <output> COPYONLY) Unlike file(COPY ...) it creates a file-level dependency between input and output, that is: If the input file is modified the build system will re-run CMake to re-configure the file and generate the build system again. both option are valid and targeting two different steps of your build: file(COPY ... copies the file in configuration step and only in this step. When you rebuild your project without having changed your cmake configuration, this command won't be executed. add_custom_command is the preferred choice when you want to copy the file around on each build step. The right version for your task would be: add_custom_command( TARGET foo POST_BUILD COMMAND ${CMAKE_COMMAND} -E copy ${CMAKE_SOURCE_DIR}/test/input.txt ${CMAKE_CURRENT_BINARY_DIR}/input.txt) you can choose between PRE_BUILD , PRE_LINK

How Many Passes Does An Insertion Sort Algorithm Consist Of? Code Example

Example: what is time complexity of insertion sort Time Complexity is : If the inversion count is O ( n ) , then the time complexity of insertion sort is O ( n ) . Some Facts about insertion sort : 1. Simple implementation : Jon Bentley shows a three - line C version , and a five - line optimized version [ 1 ] 2. Efficient for ( quite ) small data sets , much like other quadratic sorting algorithms 3. More efficient in practice than most other simple quadratic ( i . e . , O ( n2 ) ) algorithms such as selection sort or bubble sort 4. Adaptive , i . e . , efficient for data sets that are already substantially sorted : the time complexity is O ( kn ) when each element in the input is no more than k places away from its sorted position 5. Stable ; i . e . , does not change the relative order of elements with equal keys 6. In - place ; i . e . , only requires a constant amount O ( 1 ) of additional memory space Online ; i . e . , can sort a list a

Angular 5: "No Provider For ControlContainer"

Answer : The ControlContainer is a abstract class which is extended by the AbstractFormGroupDirective inside the ReactiveFormsModule . The error is thrown if you're using the ReactiveFormsModule and a <form> -element without a FormGroup bound to it via [formGroup]="myForm" . To fix this error you have to create a FormGroup and bind it to your form: <form class="container" [formGroup]="myForm" (ngSubmit)="update()"> Also make sure you have both the FormsModule and the ReactiveFormsModule added to your module imports. For Me its turns out that i imported just ReactiveFormsModule but not FormsModule. you need to import both. Turns out that the error had nothing to do with form not being bound to a formGroup , but me naming the receiving variable also formGroup . That confuses the heck out of Angular. Just renaming this variable solves the issue. That is okay now: <form class="container" (ngSubmit)=

Composer Won't Install "require-dev" Packages

Answer : Composer only ever installs the packages listed as "require-dev" of your main composer.json file, and if these packages do need something else, then only their "require" packages are installed, but not their "require-dev" packages. This actually is a good thing. If you want to contribute to an existing software package, you'd clone their repository, install everything needed for development, and are ready to contribute. But if you require that package for your own software, this is no use case to develop that particular package - it is the use case to develop your own software. So the tl;dr: Composer only installs the development requirements of the composer.json, not of any dependencies. There is a solution for installing the require-dev packages of a vendor into your project. https://github.com/wikimedia/composer-merge-plugin Add this into your composer.json of your project { "require": { "wikimedia/composer-mer
