# Deploying a Sinatra app to Heroku

## Database
The location of the database Heroku provides can be found in the environment
variable DATABASE_URL. Check the configure-block of toodeloo.rb for an example
on how to use this.

## Server
Heroku is serving your apps with thin, with means you have all your thin goodness available,
such as EventMachine.

Testing front-end for a Sinatra app with RSpec and Capybara

I've used Cucumber quite a bit on my last job. It's an excellent tool, and I believe readable tests are the way to the future. But I could never get around to write effective scenarios, or maintain the boatload of text that the suite becomes once you get to a point where you have decent coverage. On top of that, it didn't seem to take much for the suite to become really slow as tests were added.

A while ago I've seen a gist by Lachie Cox where he shows how to use RSpec and Capybara to do front-end tests. That sounded perfect for me. I love RSpec, I can write my own matchers when I need them with little code, and it reads damn nicely.

So for my Rails Rumble 2010 project, as usual, I rolled a Sinatra app and figured I should give the idea a shot. Below are my findings.

    this.remove();
    _(this.children).invoke("leave");

Deploying Rails to Linode

Installing Ruby Enterprise Edition, Apache, MySQL, and Passenger for deploying Rails 3.0 applications.

Get a Linode, and set it up with Ubuntu 10.04 LTS so that you have till April 2013 to get updates. Once the Linode is formatted, boot it and continue on.

Set up an 'A' record in your DNS, pointing to the IP of your Linode. I'm using demo.napcs.com here.

The segfault problem with posix_spawn is indeed caused by Lion's compiler being LLVM and not GCC by default. However, when I installed RVM, the notes suggested that on Lion you need to add export CC=/usr/bin/gcc-4.2 to your shell startup file (.bashrc or .zshrc as appropriate). I did that, but it seems that's what caused problems: while ruby 1.9.2 needs you to use GCC to install it, using the same compiler for the gems apparently causes breakage.

First, you need to install XCode 4.x, which is now a free (though hefty!) download from the Mac App Store. Without that, you have no gcc, so you won't get anywhere ;-)

Next, what you need to do is clear out your rvm ruby and the associated gems (make sure you are cd'd into your octopress repository then do:

rvm remove ruby-1.9.2 --gems --archive

which will clear everything out so that you can start from scratch. Obviously, if you have other stuff you've installed for other purposes using RVM, be careful with this. If you previously had the export CC li
