I like Pages.app, but don't want to deal with constantly copying and pasting code around.

Here is how I do syntax highlighting in Pages.app by pressing a key command. It's based off of this post on stack exchange.

install pygments

sudo easy_install Pygments

install github syntax

Cómo hacer un post

Escribir un post técnico puede ser una tarea compleja por diferentes razones. Primeramente está el que quizás no estemos acostumbrados a escribir en general y puede haber un poco de resistencia a hacerlo.

Cuando ya estamos convencidos de escribir, la primer pregunta es "Qué escribir?". Es muy sencillo pensar que ya todo está escrito, que no hay nada nuevo a aportar, que quizás nuestro nivel técnico no es bueno para escribir un post para otras personas.

Las dudas son válidas, pero no realistas. Si bien es posible que el tema que queremos tratar ya está escrito en múltiples posts siempre es importante e interesante el revivir un tema desde nuestro punto de vista o nuestra óptica. El nivel técnico no es tan relevante, ya que el tema o la forma de llevarlo puede ser para el nivel que tenemos o bien puede ser para ayudar a otras personas que van comenzando.

El "Qué escribir?" solamente lo podemos atacar de una manera, escribir sobre algo que nos interesa o algo en lo que trabajamos y de lo

The Task

Convert an entire folder of RAW images, typically produced by DSLR camera at 300dpi and convert them all to web-ready, 72dpi JPEG's in a single bash command while utilizing all eight threads in parallel on a quad-core i5 CPU.

Install ImageMagick with RAW support via Homebrew.

If you don't already have Homebrew, shame on you. Grab it like so:

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.
