Useful Nano Keyboard Commands

Since the nano editor doesn't really support the use of a mouse, here's a table of commands you're likely to find very useful. You should experiment with every one of them and try to memorize them, it can speed up your work tremendously. (To see a list of all nano commands, type Ctrl+g when in the editor.)

NOTE: There is no “undo” command in nano, so save your work often!

Styling checkboxes and radio buttons using CSS

The styling of checkboxes and radio buttons became possible with the introduction of the :checked pseudo-class in CSS3. This page describes two techniques: an image-based method, shown in the demonstration below, and a pure CSS method.


Image-based styling

Image-based styling allows the greatest flexibility in appearance. In the example above we combine the images for the three states (unchecked, selected checkbox, and selected radio button) into a single image for faster loading:

 HTML of the following form is used for each checkbox or radio button:

When hiring Ruby on Rails programmers, knowing the right questions to ask during an interview was a real challenge for me at first. In 30 minutes or less, it's difficult to get a solid read on a candidate's skill set without looking at code they've previously written. And in the corporate/enterprise world, I often don't have access to their previous work.

To ensure we hired competent ruby developers at my last job, I created a list of 15 ruby questions -- a ruby measuring stick if you will -- to select the cream of the crop that walked through our doors.

What to expect

Candidates will typically give you a range of responses based on their experience and personality. So it's up to you to decide the correctness of their answer.

1. How to convert a JSON into a Hash?

You’ve just retrieved a Twitter profile as a JSON:
data = '{
  "name": "Aaron Patterson",
  "screen_name": "tenderlove",
  "location": "Seattle, WA"
}'

You want to transform it as a Hash for easier data manipulation:

harssh

logger = Logger.new("#{Rails.root}+/log/sql.log",'daily') # create new logger
          logger.datetime_format = "%Y-%m-%d %H:%M:%S"
          logger.formatter = proc do |severity, datetime, progname, msg|
                    "#{datetime}: #{msg}\n"
          end    
ActiveSupport::Notifications.subscribe("sql.active_record") do |_, _, _, _, details|  # subscribe to active support notification
  if details[:sql]    # check if SQL query exists
    logger.info(details[:sql])
    end
end
