A common question among new Angular programmers - "What should be the structure of the project?". A good structure helps toward a scalable application development. When we start a project we have two choices, Sort By Type (left) and Sort By Feature (right). The second is better, especially...

Pass in a literal value (not an object), such as a string or number. Child scope gets his own value, if it updates the value, parent scope has his own old value (child scope can't modify the parens scope value). When parent scope value is changed, child scope value will be changed as well. All int...

Passing in a value by reference, you want to share the value between both scopes and manipulate them from both scopes. You should not use {{...}} for interpolation. <two-way text="'Simple text.'" <!-- 'Simple text.' --> simple-value="123" <!-- 123 Note, is...

Pass a method into a directive. It provides a way to execute an expression in the context of the parent scope. Method will be executed in the scope of the parent, you may pass some parameters from the child scope there. You should not use {{...}} for interpolation. When you use & in a directi...

Let's say you have an academic system. The bounded contexts would be like this: Admission of new undergraduate students Distribution of students on classrooms considering a schedule of the courses and occupation, size and type of classrooms Management of courses, hierarchies and predecessors of...

public class DrawRectangle { public static void main(String[] args) { //Load native library System.loadLibrary(Core.NATIVE_LIBRARY_NAME); //image container object Mat goruntuDizisi=new Mat(); //Read image in file system goruntuDizisi=Imgcodecs.imread("C:\\i...

Main features of this Makefile : Automatic detection of C sources in specified folders Multiple source folders Multiple corresponding target folders for object and dependency files Automatic rule generation for each target folder Creation of target folders when they don't exist Dependency ma...

Introduction from http://facebook.github.io/react-native/docs/native-modules-ios.html Sometimes an app needs access to platform API, and React Native doesn't have a corresponding module yet. Maybe you want to reuse some existing Objective-C, Swift or C++ code without having to reimplement it in ...

We will see stream objects being returned by modules like fs etc but what if we want to create our own streamable object. To create Stream object we need to use the stream module provided by NodeJs var fs = require("fs"); var stream = require("stream").Writable; ...

In Python: import cv2 image_path= 'd:/contour.png' img = cv2.imread(image_path) #display image before thresholding cv2.imshow('I am an image display window',img) cv2.waitKey(0) #convert image to gray scale - needed for thresholding img_gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY) ...

It is very easy to build a simple C++ project. Here is an example of a SConstruct file that does so: env=Environment() env.Program('hello', Glob('src/*.cpp')) This creates the executable hello composed of all the sources in src with extension cpp.

This example shows more detailed build settings: env=Environment( CPPPATH='/usr/include/boost/', CPPDEFINES=['foo'], LIBS=['bar'], SCONS_CXX_STANDARD='c++11') env.Program('hello', Glob('src/*.cpp')) This builds the executable hello from all the cpp files in src, with the f...

It is a dialog which prompts user to select date using DatePicker. The dialog requires context, initial year, month and day to show the dialog with starting date. When the user selects the date it callbacks via DatePickerDialog.OnDateSetListener. public void showDatePicker(Context context,int init...

This kind of schema will be useful if you want to keep trace of your items by insertion time or update time. var mongoose = require('mongoose'); var Schema = mongoose.Schema; // Creates a User Schema. var user = new Schema({ name: { type: String }, ...

The Binary Search Tree (BST) is a hierarchical data structure with a single pointer to the root node. The Node in the BST generally contains "items" (such as numbers or names) for fast look up. Each node has at-most two children (left and right). Every node is organized by some key data f...

The Cholesky decomposition is a method to decompose an hermitean, positiv definite matrix into an upper triangular matrix and its transpose. It can be used to solve linear equations systems and and is around twice as fast as LU-decomposition. A = [4 12 -16 12 37 -43 -16 -43 98]; R = chol...

This method will decompose a matrix into an upper triangular and an orthogonal matrix. A = [4 12 -16 12 37 -43 -16 -43 98]; R = qr(A); This will return the upper triangular matrix while the following will return both matrices. [Q,R] = qr(A); The following plot will display the run...

Hereby a matrix will be decomposed into an upper trangular and an lower triangular matrix. Often it will be used to increase the performance and stability (if it's done with permutation) of Gauß elimination. However, quite often does this method not or badly work as it is not stable. For example A...
