Web server comparison experiment: threaded Ruby vs. Node.js

Since a few weeks I’m working on a Node.js project at my day work, and I kind of loved the idea of the event loop, and then, because I just got off a Rails project, was wondering why wouldn’t that be possible with Ruby?

Googled a couple of evenings to find how Node.js manages to serve multiple requests on the same thread, and how its IO works. Then did the same for Ruby, read a bit about GIL, and found that in the end, there is not that much of a difference between what you can get from a threaded Ruby server and Node.js.

Played a bit with hello worlds and ended up with similar results from the speed and concurency standpoint: max 2 concurent requests on my 2CPU laptop.

For Ruby I spawn a separated Thread for every request. And from what I could google, Node.js uses a thread pool to handle the IO and one single other to run JS, which is kind of similar as far as I can understand these things. Now, I’ve tried hello world Rails and Sinatra proj

Grunt task to run jasmine-node without PhantomJS

I’m working on a project where I write a webservice on Node.js and I find that grunt-contrib-jasmine is a bit slow to start. I couldn’t find amy module on npm that would do that, so I wrote my own task:

grunt.registerTask('jasmine', [], function() {
  var exec = require('child_process').exec,
      done = this.async();

  var child = exec('jasmine-node --matchall test', function(error, stdout, stderr) {

if (error) grunt.warn(error);

JS AES encryption example

This is a quick example of how to get symmetric encryption in JS using [aes.js from the crypto-js project][1]:

// at this point http://crypto-js.googlecode.com/svn/tags/3.1.2/build/rollups/aes.js should be loaded

var data = 'a JSON blob or something',
    password = 'my long and very secretive passphrase';

var encrypted = CryptoJS.AES.encrypt(data, password).toString();

Handlebars to emulate Rails partials with locals

I’ve created a little helper that takes a partial name and a Ruby-like hash of parameters that will be passed into that partial:

Handlebars.registerHelper('include', function(partialName, options) {
  var locals = options.hash,
      context = this;

  // the included partial also inherits the current context’s data

for (var property in context) {
