An Orbit Camera is one that allows the user to rotate around a central point, but while keeping a particular axis locked. This is extremely popular because it prevents the scene from getting "tilted" off-axis. This version locks the Y (vertical) axis, and allows users to Orbit, Zoom, and P...

5.1 Every function has a bind method, which will create a wrapped function that will call it with the correct context. See here for more information. var monitor = { threshold: 5, check: function(value) { if (value > this.threshold) { this.display("Value is too high!&quot...

// An 8-bit 'byte' value: byte aByte = (byte)0b00100001; // A 16-bit 'short' value: short aShort = (short)0b1010000101000101; // Some 32-bit 'int' values: int anInt1 = 0b10100001010001011010000101000101; int anInt2 = 0b101; int anInt3 = 0B101; // The B can be upper or lower case. // A ...

Not everything in a bindings library will have the same name in C# as it does in Java. In C#, interface names start with "I", but Java has no such convention. When you import a Java library, an interface named SomeInterface will become ISomeInterface. Similarly, Java doesn't have propert...

In our last two examples, numpy assumed that a[0,:] was the first vector, a[1,:] the second, and a[2,:] the third. Numpy.cross has an optional argument axisa that allows us to specify which axis defines the vectors. So, >>> a=np.array([[1,1,1],[0,1,0],[1,0,-1]]) >>> b=np.array([0...

This code create a producer which send two messages to a queue, and a consumer which receives all the messages from that queue. Code for producer.py (using the pika 0.10.0 Python client): import pika connection = pika.BlockingConnection(pika.ConnectionParameters( host='localhost')) ch...

Flask also allows access to a CombinedMultiDict that gives access to both the request.form and request.args attributes under one variable. This example pulls data from a form field name submitted along with the echo field in the query string. Flask Example: from flask import Flask, request app...

This is an example of an unbalanced binary search tree. A binary tree is structured conceptually as a hierarchy of nodes descending downward from a common root, where each node has two children: left and right. For example, suppose the numbers 7, 5, 9, 3, 11, 6, 12, 14 and 15 were inserted into a Bi...

On 32-bit systems, integers greater than 0x7FFFFFFF cannot be stored primitively, while integers between 0x0000000080000000 and 0x7FFFFFFFFFFFFFFF can be stored primitively on 64-bit systems but not 32-bit systems (signed long long). However, since 64-bit systems and many other languages support sto...

The S in S.O.L.I.D stands for Single responsibility principle(SRP). Responsibility means in this context reasons to change, so the principle states that a class should only have one reason to change. Robert C. Martin stated it (during his lecture at Yale shool of management in 10 Sep 2014) as foll...

The most popular operating system for the Raspberry Pi is a Debian based Raspbian. It is officially supported by the Raspberry Pi Foundation. Raspbian can be downloaded from official Raspberry Pi site in one of two variants: With desktop environment Lite- Minimal image Starting September 20...

Small files are processed in a fraction of second and you can read / write them in place of the code where you need this. However if the file is bigger or otherwise slower to process, you may need to use AsyncTask in Android to work with the file in the background: class FileOperation extends A...

Occasionally we see StackOverflow Java questions (and C or C++ questions) that ask what something like this: i += a[i++] + b[i--]; evaluates to ... for some known initial states of i, a and b. Generally speaking: for Java the answer is always specified1, but non-obvious, and often difficult ...

Sometimes it is useful to print a current binding directly from markup. A neat trick which allows that is to use an additional DOM element with a non-existing binding (KO < 3.0), custom binding or a binding that is not relevant such as uniqueName. Consider this example: <tbody data-bind=&quo...

JMeter can also can be used for recording mobile performance testing. Mobile scripts recording is very similar to web application scripts recording. Configure JMeter Configure “JMeter Templates” as specified in chapter 1. Configure your mobile phone After the JMeter configuration is prepared...

Before starting with deletion I just want to put some lights on what is a Binary search tree(BST), Each node in a BST can have maximum of two nodes(left and right child).The left sub-tree of a node has a key less than or equal to its parent node's key. The right sub-tree of a node has a key greater ...

For example if the input is: Output should be false: As 4 in the left sub-tree is greater than the root value(3) If the input is: Output should be true

struct tree{ int a; tree* right; tree* left; }; tree* root=NULL; void insert(tree*& in, int b){ if(in){ if(in->a<b) insert(in->right,b); else if(in->a>b) insert(in->left,b); ...
