JavaScript closures vs. anonymous functions
...t. There's no difference between a regular function and a closure. I ran a test to prove this and it results in your favor: here's the control and here's the alternative. What you say does make sense. The JavaScript interpreter need do special bookkeeping for closures. They are simply by-products of...
Understanding recursion [closed]
... ) + sumNode( root->right ) ;
}
}
Notice that instead of explicitly testing the children to see if they're null or nodes, we just make the recursive function return zero for a null node.
So say we have a tree that looks like this (the numbers are values, the slashes point to children, and @ ...
How to use the same C++ code for Android and iOS?
...s other Unix systems. This possibility is especially useful because we can test our shared code faster, so we are going to create a Main.cpp as follow to execute it from our machine and see if the shared code is working.
#include <iostream>
#include <string>
#include "../CPP/Core.h"
i...
How can I reliably determine the type of a variable that is declared using var at design time?
... is compatible with System.Char[]?" So we start a round of convertibility testing. However, the Where extension methods are generic, which means we have to do type inference.
I've written a special type infererencing engine that can handle making incomplete inferences from the first argument to an...
How to implement a queue with three stacks?
...I could come up with, remembers me of Kirks solution to the Kobayashi Maru test (somehow cheated):
The idea, is that we use stack of stacks (and use this to model a list).
I call the operations en/dequeue and push and pop, then we get:
queue.new() : Stack1 = Stack.new(<Stack>);

What does the Reflect object do in JavaScript?

My tests where you always access properties through the proxy, results in a situation where the target is the original target that the proxy wraps, while receiver is the proxy itself. But again this could be different if you man...
How does the ARM architecture differ from x86? [closed]
... /* repeat while equal compare string bytewise */
while on ARM shortest form might look like (without error checking etc.)

What is “git remote add …” and “git push origin master”?
...named project.git. The git client and protocol honours this convention by testing for project.git when only project is specified.
git://git@github.com/peter/first_app.git is not a valid git url. git repositories can be identified and accessed via various url schemes specified here. git@github.com...
Is a statically-typed full Lisp variant possible?
... @ssice: when you're using an untyped function like eval you need to test the result to see what comes out, which is nothing new in Typed Racked (same deal as a function that takes a union type of String and Number). An implicit way to see that this can be done is the fact that you can write ...
How to calculate moving average using NumPy?
...ing_average([1,2,5,10], n=2) gives [ 1. , 3.5, 8.5]. Even the answerer's test case for a moving average of values from 0 to 19 is incorrect, claiming that the average of 0, 1, and 2 is 0.5. How did it get 6 upvotes?
