Encrypting text fields in Mongoose is easy using Node's built-in crypto module. You might want to do this if you're using MongoDB as a service (see the recent MongoHQ security breach); or, if you're storing OAuth tokens that could, in the wrong hands, screw with somebody's account on a 3rd party service. (Of course, you should never encrypt passwords: those should be hashed.)

Imagine you have a Mongoose model like that shown below, which is modified only slighly from the example on the MongooseJS homepage.

var mongoose = require('mongoose');
mongoose.connect('mongodb://localhost/test');

var User = mongoose.model('User', {
 name: String,

Mac OS Python Installation for Scientific Computing

This gist describes how to install the basic tools you'll need to do scientific computing with Python on Mac OS X. These have been tested with Mac OS X 10.6 and 10.7.

Your Mac comes with Python installed by in /usr/bin/; however, you probably don't want to use that Python because it is rarely updated and, it's not a good idea to mess with that which OS X has installed.
