Let's say I want to create and share a document, such as a blog post that has various components:

• meta information (author, categories, tags..)
• a title
• body content
• some custom styling
• some custom scripting

An HTML document seems like a great way to portably and easily package all of these things into one place:

# ruby s4d.rb "h3o w3d" 5

text = ARGV.first || "y1u a5t p1l? j2t w4d to s1y hi"
times = (ARGV[1] || 1).to_i

words = File.readlines('/usr/share/dict/words')
            .map(&:downcase)
            .map(&:chomp)

times.times do

SELECT
  schema_name, rel_name, table_size,
  pg_size_pretty(table_size) AS size
FROM (
  SELECT
    nspname AS schema_name,
    relname AS rel_name,
    pg_table_size(pg_class.oid) AS table_size
  FROM pg_class, pg_namespace
  WHERE pg_class.relnamespace = pg_namespace.oid
