Where do I start?

A good hack starts with an idea…

Build something you will use yourself

Show us what can be built using the systems we

(and others) offer.

http://developer.yahoo.com

http://www.github.com/

To build a typical web hack you need data, access

and an interface

Yahoo! has opened up its data

Search (BOSS), Flickr, Geo, Social, Mail,

Messenger…

And so have others

Programmable web lists 6670 APIs in their API

directoryTwitter, Facebook, Google, …

To access these you can use YQL

YQL is a SQL-Like Language that lets you …

… filter, combine, tweak data across hundreds of Web Services.

How will you build a system to calculate distance between two places?

Use Vincenty's formulae

Or use YQL

YQL has more to it

There’s also Yahoo Pipes to do this visually

http://pipes.yahoo.com/

Data however is not enough.

You also need working interfaces

Technologies are easy:HTML, CSS, JavaScript

Making it work on all browsers and OS is tricky

YUI

Presenting your hack

Do not show us slides about your hack

Instead show us what you have done

Technical glitches happen

Have a plan-B

Have a Plan B

• Record screencast• Do not depend on the internet• Keep your stuff ready in the browser• Rehearse the demo with atleast one crew

member before hand

And once you are done

And once you are done

• Keep your hack live for others to see• Show other hackers what you have done• Publish your code in Github• Let us know and we can help you to take it

even further!

Don’t limit yourself to your favorite toys

A good hack doesn’t need to be a big thing

Don’t look for features. Concentrate on one thing

Don’t look to solve everything

You only have 24 hours

Find things that already work

And put them together

Innovation has no limits

Go Hack !!!Have Fun
