Fixing Apachebench on OS X Lion
# If you're getting this error trying to use ApacheBench on OS X Lion:
# Benchmarking mwmanning.com (be patient)...apr_socket_recv: Connection reset by peer (54)
#
# You need to download the latest beta version of Apache and rebuild ab.
# Here's how (assuming you have homebrew installed).
# Install Homebrew (https://github.com/mxcl/homebrew) and then the Perl Regex support
brew install pcre
# Download the latest from http://httpd.apache.org/download.cgi, then decompress and compile it

Bootstrap's Typeahead plugin extended (allowing for AJAX functionality) among other things

This is a fork of Bootstrap Typeahead that adds minimal but powerful extensions.

For example, process typeahead list asynchronously and return objects

  # This example does an AJAX lookup and is in CoffeeScript
  $('.typeahead').typeahead(
    # source can be a function
    source: (typeahead, query) ->
 # this function receives the typeahead object and the query string
