conceptual

This is a conceptual question and I haven't been able to find the answer in SO, so here I go: Why instance variables are used to connect controllers and views? Don't we have two different objects of two different classes (Controller vs Views). So, when the view is rendered we are in a different context, but we are using instance variables of another object? Isn't this breaking encapsulation in somehow? How does Rails manage to do that matching from one object to another? Does it clone all the instances variables of the controller to the view? In a sense, you could say that it is breaking

Using Chrome Browser DevTools I wanted to add a custom device in the Emulated devices tab . You can choose several options such as the width and height. And also choose between: Mobile Mobile (no touch) Desktop Desktop (touch) So the difference between Mobile and Desktop doesn't seem to be the touch events . Is a device of 1000*1000px screen size Mobile (no touch) and a device of 1000*1000px screen size Desktop the same? Or a device of 1000*1000px screen size Mobile and a device of 1000*1000px screen size Desktop (touch) the same? So my question is: What is the difference between Desktop and

Approaching cmdlets in a conceptual way, How are they made? Are they compiled? Is it the equivalent of a batch file for PowerShell? Is it a script or a binary? What is the structure used for storing these cmdlets? A PowerShell cmdlet is a compiled piece of .NET code, more precisely a single class if I am not mistaken. Cmdlets are kind of the "native" commands in PowerShell land, being able to handle object input and output as well as usually playing nice and well with the (object-based) pipeline. Cmdlets have no direct representation in the file system, as they are not programs or similar.

One example is given by one of our trainers when he was explaining difference between CountDownLatch and CyclicBarrier. CountDownLatch : Suppose a stone can be lifted by 10 people so you will wait for all 10 to come. Then only you can lift the stone. CyclicBarrier : If you are going to a picnic, and you need to first meet at some common point from where you all will start your journey. If Anybody agrees with these comments please give me some details. I have already read the sun API for both these classes. But I need some more explaination. The key difference is that CountDownLatch separates

i have to generate random numbers for 3 different cases. i. 1 dice ii. a pair of dice iii. 3 dices my questions: 1. please suggest me sm good logic to generate random numbers for all the 3 cases. 2. does the logic change when i consider the cses of 2 dices, rather than 1? 3.how much of an effect does the range in which we have to genrate a random number affect the logic of the random function? If the range is small enough, you shouldn't have problems in using the usual modulo method int GetRandomInt(int Min, int Max) { return (rand()%(Max-Min+1))+Min; } (where Min a Max specify a closed

The Java Platform includes a powerful API for capturing, processing, and playing back audio and MIDI (Musical Instrument Digital Interface) data. This API is supported by an efficient sound engine which guarantees high-quality audio mixing and MIDI synthesis capabilities for the platform. The provided reference implementation of this API supports the following features: Audio file formats: AIFF, AU and WAV Music file formats: MIDI Type 0, MIDI Type 1, and Rich Music Format (RMF) Sound formats: 8-bit and 16-bit audio data, in mono and stereo, with sample rates from 8 kHz to 48 kHz Linear, a-law

I Learned About 2's Complement and unsigned and signed int. So I Decided to test my knowledge , as far as i know that a negative number is stored in 2's complement way so that addition and subtraction would not have different algorithm and circuitry would be simple. Now If I Write int main() { int a = -1 ; unsigned int b = - 1 ; printf("%d %u \n %d %u" , a ,a , b, b); } Output Comes To Be -1 4294967295 -1 4294967295 . Now , i looked at the bit pattern and various things and then i realized that -1 in 2's complement is 11111111 11111111 11111111 11111111 , so when i interpret it using %d , it
