The document discusses a 2 day hackathon where participants were required to use new technologies like node.js, mongodb and rails. They learned that setting up development infrastructure and learning new technologies can be costly and that deadlines and accountability are useful. It also provides code samples for inserting data into mongodb and fetching tweets with a specific hashtag.

1. tweet now with #webtuesday,
listeners are standing by
Hacking for fun and profit
(with node.js, mongodb and rails)

2. who the hell are they?!...

3. what?
2 Day Hackathon
requirements:

4. why?...
because we wanted to be rich and
famous like Zuckerberg
(...or at least, to have fun and learn something new)

5. what we've learned
don't underestimate the cost of setting up dev infrastructure
or the cost of learning new technology
a deadline is useful
accountability is good

6. what we've learned
rake and cap are cooler than make and ant
hidden cost of third party dependencies
no easy answers to hosting questions
moving to NoSQL might be easier than you think

7. script to insert into mongodb
var mongo = require('mongodb'),
db = new mongo.Db('wt', new mongo.Server('localhost',
27017, { },{ });
db.open(function(){
db.collection('attendees', function(err, collection)
{
var attendee = { name: 'foo', age: 42}
collection.insert(attendee, function(){ });
});
});

8. script to fetch tweets (by hashtag)
var TwitterNode= require('twitter-node')TwitterNode,
sys = require('sys');
var tn = new TwitterNode({
user: 'your username',
password: 'your password',
track: ['webtuesday'] });
tn.addListener('tweet', function(status){
sys.put(status.user.screen_name);
}).stream();
