When reading your code, the Strategy Pattern alarm goes off in my head. Before that however, I have some other remarks.
Indentation. If you are using Eclipse, please select your code and press Ctrl + I to indent your code properly. Please read up on indentation in the Java Coding Conventions

have been handwriting an MD5 Hash function (for learning) and I've encountered a problem and I'm not completely sure what it is. The problem is in the line that declares temp; for some reason, I'm getting incorrect values for a, b, c and d, but only on case 3. Help?

I am stuck on something I know should be really simple to fix but I just can't figure it out I've been Google-ing and gone through my text (Gaddis C++ Intro, Ch. 6) and tried a few things - mostly moving the loop around as I thought I placed it wrong; I've searched through several C++ forums as ...
This function has very slightly different boundaries, but you may find it does better than what you have right now:
function degreesToOrientation(degrees){
return 1 + Math.floor(((Math.abs(degrees) + 180 + 11.25) % 360) / 22.5);
}
one sixteenth of a circle is 22.5 degrees. centering that i...
Some recent discussions on this site involved the Fizz-Buzz game - I have never actually implemented this, but for the record this is what I put together:

The usual way to create a plugin is to declare a namespace or use an existing and append to it. Usually done using the module pattern:
(function(ns){
//private scoping
var privVar = '...';
function priv(){...}
//expose a function
ns.myFunc = function(){...};
}(this.myLib = this.myLi...

Points that I have considered:
1) Make the class final so that it cannot be extende...
I've been reading about WeakPointer and WeakPointer<T> today, and it looks very useful. Rather than just using it as-is though, I decided to write a wrapper around it that covers a common usage case for me.
Code as follows:

{
Func<T> generator = nu...

I must read and extract some values from string. These values are coded like this:

Guys i just wrote this simple code. I have a problem. I get the factorial for small numbers but if i enter number like 45 or above i get 0 as the factorial. Why is that? Check and let me know what you think of this:

I'm curious about Object.defineProperty. It seems awfully verbose for not doing much more than what you can already do in the constructor. What's the point of it? Would it be 'bad code' to not use it? I know you have more control over read/write and enumerability with defineProperty, is that ...
I am building an web application that is going to work in a similar way like photoshop or illustrator regarding layers.

We have a binary tree, suppose like this:
8
/ \
6 10
/ \ / \
4 7 9 12
/ \
3 5
We have to print this binary tree in top-down manner - column wise. Note that, 8, 7 & 9 would be considered in same column. So the required output should be:
3
4
6 5
8 7 9

I tried implementing Integer Partition (enumerating all possible sets of whole numbers whose sum is a given integer).
Looking at @rolfl's answer, I reasoned that with a stack data structure, we shouldn't need to use recursion, since recursion implicitly stores state in the call stack. I also tr...
