How It Works


Sign-In & Auth for Buzz

client = buzz.Client()
client.build_oauth_consumer(
  OAUTH_CONSUMER_KEY,
  OAUTH_CONSUMER_SECRET
)
client.oauth_scopes.append(
  buzz.FULL_ACCESS_SCOPE
)



request_token =
  client.fetch_oauth_request_token(
   'http://example.com/oauth/callback/'
  )
# Save request token to the data store
authorization_url =
  client.build_oauth_authorization_url(
   request_token
  )



# User visits the authorization_url


verifier = request.get('oauth_verifier')
# Lookup request_token in data store
client.oauth_request_token = request_token
access_token =
client.fetch_oauth_access_token(verifier
)
# Save access token to the data store


Generate Board
# Create a new board
topic_choices =
  copy(models.board.TOPIC_LIST)
topics = []
# Select 24 topics at random.
# Center square is free space.
while(topic_choices and len(topics) < 24):
  element = random.choice(topic_choices)
  topic_choices.remove(element)
  topics.append(element)


Generate Board

for x in xrange(5):
  for y in xrange(5):
   if x != 2 or y != 2:
   # We skip over the 'Free Space'
   square = models.board.Square(
   parent=self,
   key_name=('%d:%d' % (x, y)),
   topic=topics.pop()
   )
   square.put()
   board[x][y] = square


Board Marked

for topic in models.board.TOPIC_LIST:
  if comment_text.find(topic.lower()) != -1:
   topics_found.add(topic)
# Calculate the topics we can score on
intersection = [
  topic for topic in player.topics
  if topic in topics_found
]
if intersection and
   not player.has_post_scored(post_id):
  scoring_topic = random.choice(intersection)
  player.score_post(
   post_id, post_uri, scoring_topic
  )


Board Marked
if post.attachments:
  for attachment in post.attachments:
   if attachment.type == 'article':
   self.award_badge('share')
   break
if post.geocode and
   post.actor.id != self.key().name():
  self.award_badge('geo')
elif post.geocode:
  self.award_badge('mobile')


Board Marked

# Create the attachments for the post
badge_attachment = buzz.Attachment(
  type='photo', enclosure=badge.badge_icon
)
link_attachment = buzz.Attachment(
  type='article',
  title='Buzz Bingo',
  uri='http://buzz-bingo.appspot.com/'
)


Board Marked
# Assemble our announcement Buzz post
badge_post = buzz.Post(
  content=post_content,
  attachments=[
   badge_attachment,
   link_attachment
  ],
  geocode=VENUE_GEOCODE,
  place_id=VENUE_PLACE_ID
)
# Create the post
self.client.create_post(badge_post)


Bingo!

horizontal_counts = [0, 0, 1, 0, 0]
vertical_counts = [0, 0, 1, 0, 0]
for x in xrange(5):
  for y in xrange(5):
   if self.board[x][y] and
   self.board[x][y].post_id:
   horizontal_counts[y] += 1
   vertical_counts[x] += 1


Bingo!

if (5 in horizontal_counts) or
   (5 in vertical_counts):
  self.award_badge('bingo')
  if not self.bingo_count:
   self.bingo_count = 0
  self.bingo_count += 1
  self.put()

Idea Starters

• Multi-site photo viewer: consume photos and render them in a lightbox
• Event search (like BuzzWatching: restrict by date, and add location as well):
deal with the types and generate different renderings. Tweak ranking by
weighting
• Best Of Day/Week/Month viewer
• Community Finder: cluster people in your extended social around a topic
• People Finder: ﬁnd people in your geographical area who have similar
interests


Idea Starters

• Trending topics. Topics or posts that are accelerating in the last N minutes.
• Hot places: FInd places that have the most activity within a given geographic
area.
• Buzz List (like Reader bundles): Allow users to create and share collections of
other users. Allow them the ability to subscribe to lists of other users.
• Auto-follow: based on my remote account (e.g. Flickr)
• Spoiler detection: scan the user's consumption API and mute posts that talk
about certain TV shows.
