@kissmehere and there! and there! and there! Kissing Booths FTW!

Last night at makerlab we were talking about dating sites a bit – we had some fun thinking about the different ways that we could imagine designing a simple tool for twitter. We decided we wanted it to be really really simple.

Like REALLY REALLY simple. Like this:

twitter.com/kissmehere

Kinda like a kiss. Yeah, just like that. Like a kissing booth! JUST like a Kissing Booth!

kisses!

The way this all works is that when you send a message to @kissmehere on twitter and you include the name of some people, it will send a kiss to all those people. For example:

@kissmehere go kiss @paigesaez @zephoria @soycamo @semaphoria @anselm

Kissmehere is no prude, you can kiss more than one person at the same time – or kiss only one person – it is up to you.

Kissmehere maps your kisses too!

How did I build it? This is just a riff on the same twitter code I have been using before. There are a few twists. First we have some pre-amble and we have a geocoding engine – thanks MetaCarta!!!:


require 'rubygems'
require 'dm-core'
require 'twitter'
require 'net/smtp'
require 'net/http'
require 'uri'
require 'json'
require 'dm-core'

#
# passwords
#
TWITTER_USER_NAME = "kissmehere"
TWITTER_PASSWORD = ""
METACARTA_USERID = ""
METACARTA_PASSWORD = ""
METACARTA_KEY = ""

#
# a very very nice metacarta utility to brute force discover location in text
#
def geolocate(location)
  location = URI.escape(location, Regexp.new("[^#{URI::PATTERN::UNRESERVED}]"))
  # location = URI.escape(location)
  host = "ondemand.metacarta.com"
  path = "/webservices/GeoTagger/JSON/basic?version=1.0.0"
  path = "#{path}&doc=#{location}"
  data = {}
  begin
    req = Net::HTTP::Get.new(path)
    req.basic_auth METACARTA_USERID, METACARTA_PASSWORD
    http = Net::HTTP.start(host)
    #if response.is_a?(Net::HTTPSuccess)
      response = http.request(req)
      puts response.body
      data = JSON.parse(response.body)
    #end
  rescue Timeout::Error
    # DO SOMETHING WISER
    return 0,0
  rescue
    return 0,0
  end
  begin
    lat = data["Locations"][0]["Centroid"]["Latitude"]
    lon = data["Locations"][0]["Centroid"]["Longitude"]
    return lat,lon
  rescue
  end
  return 0,0
end

We have a simple data model as usual to track our activity… again using datamapper which is a favorite of mine.


#
# Only send out 10 tweets at a time
#
twittercap = 10

#
# Grab a database
#
DataMapper.setup(:default, {
    :adapter  => 'postgres',
    :database => "kissmehere",
    :username => '',
    :password => '',
    :host     => 'localhost'
})

#
# here is our schema
#
class Kiss
  include DataMapper::Resource
  property :id,          Integer, :serial => true
  property :provenance,  Text
  property :uuid,        Text
  property :title,       Text
  property :link,        Text
  property :description, Text
  property :screenname,  Text
  property :userid,      Text
  property :location,    Text
  property :lat,         Float
  property :lon,         Float
  property :secret,      Integer, :default => 0
  property :friended,    Integer, :default => 0
  property :kissed_at,   DateTime
  property :created_at,  DateTime
end

We have the usual twitter gem code to peek at the twitter state. I am really starting to wonder how the heck twitter even stays up with the amount of traffic it is getting… In any case mine is not to worry but to do!

#
# Remember kiss requests
#
twitter = Twitter::Base.new(TWITTER_USER_NAME, TWITTER_PASSWORD )
twitter.replies().each do |twit|
  uuid = "#{twit.id}"
  kiss = Kiss.first(:provenance => "twitter", :uuid => uuid)
  next if kiss
  secret = 0
  secret = 1 if twit.text[/ secret/] != nil
  lat = 0
  lon = 0
  if twit.user.location && twit.user.location.length > 1
    lat,lon = geolocate(twit.user.location)
  end
  kiss = Kiss.create(
             :provenance => "twitter",
             :uuid => uuid,
             :title => twit.text,
             :link => nil,
             :description => nil,
             :screenname => twit.user.screen_name,
             :userid => twit.user.id,
             :location => twit.user.location,
             :lon => lon,
             :lat => lat,
             :secret => secret
          )
  kiss.save
  puts "Saved a kiss on twitter! #{kiss.userid} #{kiss.title} #{kiss.lat} #{kiss.lon}"
end

Next we want to respond to kisses in an intelligent way; telling everybody, friending new friends and all that kind of fun stuff.


#
# Pass new kisses onwards ( only do twittercaps worth )
#
@kisses = Kiss.all(:order => [:created_at.desc],
                   :limit => twittercap,
                   :kissed_at => nil
              ).each do |kiss|

  # tease each kiss apart for multiple receivers
  kisses = kiss.title.scan(/\@\w+/)
  kisses.each do |luckyduck|
    next if luckyduck == "@kissmehere"
    if kiss.secret == 0
      kiss.link = "http://twitter.com/#{kiss.screenname}/statuses/#{kiss.uuid}"
      gossip = "#{luckyduck} got a kiss from @#{kiss.screenname} - see #{kiss.link} "
      # if kiss.lat != 0 && kiss.lon != 0
      #  gossip = " - #{gossip} near #{kiss.location}"
      # end
    else
      kiss.link = nil
      gossip = "@#{luckyduck} got a kiss from an anonymous admirer!"
    end
    kiss.description = gossip
    result = twitter.post(gossip)
    puts "Told everybody #{result} of #{gossip}"
  end
  if kisses.length == 0
    puts "No love from #{kiss.screenname}"
  end
  kiss.kissed_at = DateTime.now
  kiss.save

  # friend everybody - could improve this
  begin
    twitter.create_friendship(kiss.screenname)
  rescue
  end
  kisses.each do |luckyduck|
    begin
      #if twitter.friendship_exists(TWITTER_USER_NAME,luckyduck)
      twitter.create_friendship(luckyduck)
    rescue
    end
  end

end

Finally we write out an RSS feed for Google Maps – thanks @ajturner for the quick tip. I wasn’t able to get ruby rss maker to do anything useful such as allow me to specify custom namespaces for the geo:lat and geo:long attributes so I wrote everything by hand! By doing this we can then make a map page which has all the kisses on it just for fun. I guess I won’t show this blob because it breaks the layout engine in wordpress… I will link to the original file however at agent.txt

That’s it. Have fun out there in the twitter verse!
