Jesse's HelloWorld in Solidity

HelloWorld.sol.js

pragma solidity ^0.4.0;
contract HelloWorld {
    
    uint private magicNumber;
    address private magicPerson;
    
    
    // constructor
    function HelloWorld() public {
        log0("HelloWorld constructor started");
        
        // create a random number between 1 and 10;
        // reference: https://www.reddit.com/r/ethereum/comments/442z66/how_to_generate_a_number_between_110_in_solidity/
        magicNumber = uint(block.blockhash(block.number-1))%10 + 1;
    }
    
    function setMagicNumber(uint _number) public{
        log0("Setting Magic Number");
        
        // error checking, don't wanna waste gas
        require(_number != magicNumber);
        
        magicNumber = _number;
        magicPerson = msg.sender;
    } 
    
    
    function getMagicNumber() public constant returns(uint magic){
        return magicNumber;
    }
    
    function getMagicSender() public constant returns(address){
        return magicPerson;
    }
    
    function getMagicSha() public constant returns(bytes32){
        //return keccak256(magicNumber);
        return keccak256( getMagicNumber() );
    }
    
}

Changed extension to .js for code highlighting, .sol just showed black text.
