Learn You a Haskell presents the Caesar Cipher:
The Caesar cipher is a primitive method of encoding messages by
shifting each character in them by a fixed number of positions in the
alphabet
Here's my implementation:

Here is a sample start of function reversed from a easy program.
My question is that
why memory are not allocated consecutively and some parts of the memory are not used?
In sub esp, 70h, the number 70h seems a random number in different program and it is often larger than we needs. Why not t...

In SO I asked for a way to do it without variadics. I also provided a typical "normal" implementation with variadics :

Im currently working on a form object implementation and Im about to take a step back and refactor the whole thing.

Given a hashmap (or a "Dictionary") as a JavaScript object, I'd like to get the value who has the maximum Key - assuming the Keys are integers.
In case there's more than one, I don't care which one of them.

I can extract the des...

I'm learning ruby here: http://ruby.learncodethehardway.com:
Use only STDIN.gets and try the script that way. Think of why one way of getting the filename would be better than another.

I've been working on a game for a little while in python and whilst doing some research on particle systems I came across this video, which certainly struck my fancy. Would it be feasible to implement something like this in video game, in python? It seems like a stretch, and I have my doubts that...
My code
def tripleAll(nums):
for trip in [nums]:
new = trip * 3
print(new)
Then I would call the function with multiple numbers, like so.
tripleAll(3, 6, 7)
But, when I do this, it says it can only take one positional argument. How can I make it so it takes multiple?

I have some small "plugin system" (not sure this is right name). It allow you to store objects (plugins), and then call some methods from each of them. With this approach we have absolutely no overhead on iterating/object pass/callback call.

I have designed a simple state machine for the following diagram:
I am seeking improvements from the community. I don't like especially two things:
1. When calling performAction I wan't to send only the action without the callback.
2. And maybe remove the Action enum from the Engine class.

So I decided to try out Python (3.x) two or so weeks ago, and this is my first real script using it. The program I've written below is slow, clunky, inefficient, inaccurate, and probably poorly coded! But it produces what I want most of the time, and it was really just a project to become accusto...

I have a habit of aligning equal signs when assigning values to variables or indexes in arrays. For example, instead of doing this:
$data['foo'] = '';
$data['fooBar'] = '';
$data['reallyFooBar'] = '';
$data['fooVar'] = '';
I'll do this:
$data['foo'] = '';
$data['fooBar'] = '';

This is wrong:
area = double area (double length, double width);
You're returning the value from area(), not declaring it. Just call the function:
area = area(double length, double width);
Your calculation in area(double radius) is incorrect:
area = PI * (radius * 2);
That is calculatin...
As a LISP (and FP) newbie, I wrote the following code that finds the sum of all the multiples of 3 or 5 below 1000, and I suspect that it is lousy:
