My problem is the following: I wrote a method, which counts words and returns a hash. There is a Ruby idiom which was found by me in some of the forums discussions, which I don't understand.
Here is the whole code:
text = "bla bla blahh blahh"
def count_words(string)
inp = string.downcase.scan(/\b[\'a-z]+\b/i).inject... |
I wrote a string escaping function in C, and I'm trying to rewrite it to Haskell. The C version, along with comments explaining why it does what it does, can be found on GitHub.
Here's a naïve implementation based on Data.ByteString.concatMap:

I'm writing a simple text-based RPG in Java. I think it's a good exercise to practice OO and think about how objects should best interact. I'd be interested in hearing any thoughts!
The Game class contains a single game:

As every map shall consist of SVG and Image elements, which can be grouped in layers, which in turn can be set invisible, I need an API to reflect this functionality. I started with two classes/prototypes:

Trying to implement something like CommandLineToArgV:

// ""s are required
throw MalformedEscapedSequence();

Question:Write an algorithm in C to do integer multiplication without using multiplication nor division operators.
Could I get a critique of the doMultiplication function? I know the rest of the code has some dumb stuff in it (like using scanf), but I'm looking for feedback on my multiplication implementation. Are ther... |
Basically, I'm comparably new to Haskell, which means lacking both knowledge of advanced principles, available libraries and, maybe, some syntax.
For educational purposes I hacked together a code implementing Stam-style fluid dynamics solver. For now the code is running in constant space and linear time, which is exact... |
