Renaming table in Ecto migration

I recently wanted to rename a model and its postgres table in a Phoenix app. Renaming the table was simple and documented, but the table also had constraints, sequences, and indexes that needed to be updated in order for the Ecto model to be able to rely on default naming conventions. I couldn't find any examples of what this would look like but was eventually able to figure it out. For anyone else in the same situation, hopefully this example helps.

In the example below, I'm renaming the Permission model to Membership. This model belongs to a User and an Account, so it has foreign key constraints that need to be renamed.

defmodule MyApp.Repo.Migrations.RenamePermissionsToMemberships do
  use Ecto.Migration

Tips about drawing digitally

I asked on https://www.facebook.com/groups/1014974001864957/permalink/1252338398128515/ and these were the main points:

• Set the tablet settings, on the driver and on the software used for drawing. For example, pressure sensitivity.
• Check the projection: what screen you're using to project the table and ensure the "constrain proportions" setting is checked.
• Consider line stabilizing software like Lazy Nezumi Pro (only Windows so far). Sketchbook Pro has this sort of line as well.
• Use Mischief rather than Photoshop for line drawing. It's simpler and produces more natural line drawing, which can be later exported for rendering in Photoshop.
• Get comfortable with using undo constantly.
• Use hard felt nibs for the tablet, the have increased friction and feel more like a pen on paper.

#Heroku, Ruby on Rails and PhantomJS

In this post, I’m going to show you how to modify an existing Ruby on Rails app running on Heroku’s Cedar stack to use PhantomJS for screen scraping. If you’ve never heard of PhantomJS, it’s a command-line WebKit-based browser (that supports JavaScript, cookies, etc.).

Let’s get started. This is a high-level overview of the required steps:

• Modify your app to use multiple Heroku buildpacks.
• Extend your app to use both the Ruby as well as the PhantomJS buildpacks.
• Confirm that everything worked.

Ruby, RVM and Mountain Lion

Key problems

Mountain Lion (10.8) has three main difference compared to Lion (10.7):

• XCode 4.4 does not install Command Line Tools by default
• X11 isn't available anymore
• The installed version of OpenSSL has some bugs

How to work around

P = programmer; NP = non-programmer

  NP: How long will it take?
  P:  It'll take as long as it takes.
  NP: I don't understand. What does that mean?
  P:  When you tell me that the product is finished, it's done.
  NP: You mean you can't estimate how long it'll take?
  P:  I can't estimate when you'll decide that it is done, therefore an
      accurate prediction is impossible.  From experience I know that a
      project like this can take from three to nine months.  A lot
