I've written a simple subscriber event system taking advantage of std::function. It works great! (and I can do some big enhancements later with thread-pooling for expensive callbacks)
The next step to improve this is to handle events/callbacks with more than one parameter.
Other than forcing s...
A Dictionary is the wrong data structure to use for memoization here. An ArrayList would be more appropriate. The reason is that the entries are not independent, but rather sequential: it will remember all entries from the 0th to some maximum. There's not much point to hashing when a simple ar...
I have this implementation of the FizzBuzz challenge in Ruby:
(1..100).each do |n|
i_3=(n%3==0)
i_5=(n%5==0)
case
when i_3&&i_5
puts 'fizzbuzz'
when i_3
puts 'fizz'
when i_5
puts 'buzz'
else
puts n

Inspired by this question: Fraction (rational number) structure with custom operators, I have written this class for doing some simple work with fractions.
Fraction.h:
#import <Foundation/Foundation.h>
@interface Fraction : NSObject
@property int numerator, denominator;
-(void) print;
-(void...
First, the struct itself:
struct Fraction {
var numerator: Int
var denominator: Int {
didSet (oldDenominator) {
if self.denominator == 0 {
self.denominator = oldDenominator
}
}
}
init() {
self.init(numerator: 0, denominator: 1)
}
...

If f is a numerical function and n is a positive integer, then we can form the nth repeated application of f, which is defined to be the function whose value at x is f(f(...(f(x))...)). For example, if f adds 1 to its argument, then the nth repeated application of f a...
I am studying for a degree in "Bachelor of Engineering in Information and Communication Technologies." I am currently on vacation, just after we started learning C++ at the end of the semester. I wanted to be ahead of the next semester, so I decided to try to use these classes and to make a text...
Here, is an article on password hashing, along with an implementation. Is this code secure with number of iterations 10000, key length 256 and salt bytes 32? Are there vulnerabilities or incorrectly implemented sections in this code? Related questions (1) through (5) are inline.

I went ahead and I implemented a method to calculate Fibonacci numbers using memoization.
public class MemoizedFibonacci {
private static final List<BigInteger> FIBONACCI_LIST = new ArrayList<>();
static {
FIBONACCI_LIST.add(BigInteger.ZERO);
FIBONACCI_LIST.add(BigInteger...
Besides the comments you've already received, I'm adding some more:
Many of your variables can be marked as private final. All of them can be marked private and those who get initialized directly and never change should also be marked final. These include:
Game g = new Game();
Scanner s = new...
Installed node.js v0.10.29 which ships with npm v1.4.14
Updating npm to v1.4.20: npm install npm -g (successfully)
Checking version: npm -v (still v1.4.14)
Although the new version of npm is installed to %AppData\npm\node_modules, the CLI recognizes the one that's being shipped with note (C:\P...
I found a nice lightbox2-fork, which I tried to improve.
After about six hours of work the code passes jslint.
I also tried to change variable names for better understandig of what they are for.
What else can be improved there?
Also, I'd like to change one behaviour of this script:
Images ar...
Okay others have good points, I would like to add a new one. The logo is size challenged in that the details are a bit too small. This may be a problem if you need to:
work in small scales such as 24 x 24 pixel icons (or even smaller)
Print a business card sized medium, you would now need the r...

I am actually pretty damn proud of this code, it's my first complex algorithm I have made.
Basically it sets a shapes default size and radius based on how many characters are in a string that is passed to it, the user gets the option to manually set the Font, otherwise it is automatically set for...
