uno o dos

after all this time, I still get a chuckle every time I read - hard to believe it was serious...

Now in Ruby, strings can be created using single or double quotes. The only difference is that you can interpolate variables in double quoted strings. I constantly see the following confusing code: user.name = "name" link_to "home", root_path Here we’re using double quoted strings, but there’s no interpolation. As soon as I see double quotes, I think there’s going to be some interpolation. Using double quotes without interpolation is flat out wrong. The above code is more correct, and much less confusing using single quotes. user.name = 'name' link_to 'home', root_path This may not seem like much, but it makes a huge difference when followed consistently.
