Say you have a model set with many items.  In Ember:
set.items[0]    #incorrect
  =>  
set.get("items").objectAt(0)

Error: Failed to load unit/state_managers_spec.js.coffee
- could be one of the require statements file name incorrect

Uncaught Error: assertion failed: Cannot call get with 'id' on an undefined object.     (em1.0.rc1)
- make sure link is properly defined 
    e.g. {{#linkTo item}} will cause problems: should be {{#linkTo item item}}

Uncaught TypeError: Object <(generated set controller):ember417> has no method 'addArrayObserver'   (em1.0.rc1)
- can happen when controller is Em.ArrayController but should be Em.ObjectController (perhaps no array defined)

Ref:
http://docs.mongodb.org/manual/reference/mongodump/
mongorestore --collection people --db accounts dump/accounts/

Say you want to transfer your local mongo dbs to another machine.  One way using dump and restore is:

1. run mongodump on old machine
- this will put all your mongo dbs in a directory called dump in the current dir
- for instance if you have one db called mydb, will have a dir dumb/mydb with your data

c. Devise 2.1.2
ref: https://github.com/plataformatec/devise/issues/1561


E.g. you may want to send back json instead of html on login, etc.

Steps:
1. Override the controller (put in the controllers dir)

class SessionsController < Devise::SessionsController

c. 0.5.2

Make sure not doing .to_json

This will not work!!!
render :json=>songs.to_json

This works:
render :json=>songs

c. jqm 1.2

  $(document).on "tap", someSelector, (event) ->
    log "evX", event.clientX
    log "evY", event.clientY

seems to work with tap, vmouse, etc.

c. JQuery 1.8

for some reason this only works about half the time.  rather than waste time on mindless and costly debugging instead always use:

$(someField).attr "value", val

c. UMongo 1.2.1
In the server text field, change 'localhost' to '127.0.0.1' and it should work
