// Apply a CSS text-shadow cross-browser.
// There is one todo/gotcha: the direction is hardcoded to towards the bottom-right for IE, but that's good enough for my use case.
// Usage example: +text-shadow(#333, 1px, 1px, 1)

=text-shadow(!color, !x, !y, !blur)
  :text-shadow= !color !x !y "#{!blur}px"
  :-ms-filter "progid:DXImageTransform.Microsoft.Shadow(Color=#{!color},Direction=135,Strength=#{!blur})"

/ This SASS function makes it easy to get cross-browser opacity.
/
/ Firefox and Safari use CSS opacity.
/ Internet Explorer 7 and 8 each require their own flavor of the opacity alpha filter.
/
/ See http://www.quirksmode.org/css/opacity.html for more info on opacity.
/
/ Pass an opacity value between 0.0 and 1.0
=opacity(!value)

# Simple message filtering logic for a Ruby-based Twitter client.
#
# This demonstrates two simple string-based filtering approaches: 
# * blacklist words
# * blacklist phrases
#
# It uses a slightly optimized matching and shows a sub-optimal one as comment.
#
# This can ofcourse also be used for highlights, dynamic grouping and whatnot.

  # An unordered group_by implementation that is a gazillion times faster than
  # ActiveSupport's ordered version, when used with large data sets.

  # way slower than Hash#[] because it does a linear search vs a tree search.
  # For small data sets, the difference is not that obvious, but in the range
  # of 50k+ items, the difference can be 60 seconds vs less than 1 second.
