a proper fibonacci server in node. it will light up all your cores.

fib.js

var http = require('http')
var fork = require('child_process').fork;

function fib(n) {
  if (n < 2) {
    return 1;
  } else {
    return fib(n - 2) + fib(n - 1);
  }
}

if (process.argv[2] == 'fib') {
  var r = fib(40);
  process.send({ result: r });
  process.exit(0);
} else {
  var server = http.createServer(function(req, res) {
    var child = fork(__filename, [ 'fib' ]);
    child.on('message', function(m) {
      res.writeHead(200);
      res.end(m.result + "\n");
    });
  });
  server.listen(8000);
  console.log("server online at http://localhost:8000/")
}

OMG and heres a version with just one line of code

var http=require("http"),pool=require("threads_a_gogo").createPool(5).all.eval(fib);function fib(a){return 2>a?1:fib(a-2)+fib(a-1)}var server=http.createServer(function(a,b){pool.any.eval("fib(40)",function(a,c){b.writeHead(200);b.end(c+"\n")})});server.listen(8E3);console.log("server online at http://localhost:8000/");

Point being.. Lines of code are pointless.

oh god, node fanboys make me wanna puke :[

@kybernetyk your profile just made me puke
