A simply way of DRYing up promise-returning functions
# There's an incredibly common pattern when using promises:
#
# myFunction: ->
# dfd = $.Deferrred()
#
# $.ajax "wherever"
# .done() ->
# dfd.resolve("yep")
# .fail() ->
# dfd.reject("nope")

Allow Backbone's `get` to return multiple values

Improving Backbone's get to accept multiple arguments

CoffeeScript makes this work well:

[name, age] = user.get('name', 'age')

It would be trivially easy to allow Pam.Model's get to override Backbone's get to support this

CoffeeScript gotcha - implicit objects on multiple lines

A short list of CoffeeScript gotcha's I've encountered writing CoffeeScript professionally.

These are not problems with CoffeeScript, rather they are strange one-off situations where, especially coming from Ruby, differences in CoffeeScript's syntax have led to unexpected JavaScript.

Ultimate rebase-onto-master guide

Rebase "web-123-my-branch" onto master:

if you're the only person who is working on a branch...

$ git checkout web-123-my-branch # make sure you're on the right branch
$ git fetch # update remote refs
$ git rebase origin/master # perform the rebase onto the current state of master
  # for each conflict, edit file, resolve conflicts, git add -u <file>, git rebase --continue
$ git push -f origin web-123-my-branch # overwrite remote branch with newly rebase branch
