Hacking for innovation

Hacking???

There are few myths about Hacking

Hacking is a good thing

Cracking is Evil

In the Yahoo! sense, hacking is about solving problems innovatively

And a hacker is …

What is this Hack U thing?

Talks for two days about different things you can

hack on

24 hours of un-interrupted,

unrestrained coding and innovation

Hack

Eat

Get Help

Recharge

Hack

Fix

Present

Win

The question is though: where do I start?

A good hack starts with an idea…

Fix something you use every day�

Build something you will use

yourself

Hack for Good - Make the world a

better place

Go local – tools for helping your local

community

Don’t concentrate on 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 for features.

You only have 24 hours

Find things that already work

And then put them together

We want you to show us what�can be built using the systems�

we (and others) offer.

Some great resources

http://developer.yahoo.com

To build a typical web hack you need data,

access and an interface

Yahoo! has opened up its data

Search, Flickr, Geo, Placemaker, placefinder, Social,

News, Finance, Mail, Messenger, Address Book, Maps, Ansers

…

Also Others

Youtube, Twitter, Facebook, Google, Craigslist, Imdb,

Last.fm …

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

Select kilometers FROM geo.distance where

place1=“kolkatta” AND place2=“kharagpur”

Translate tweets

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

So, we have YUI!

http://developer.yahoo.com/yui

What about reach?

You can build and wait for people to come

Or build where people are already

there

Presenting your hack

Do not show us slides about your hack

Powerpoint = Fail!

Instead show us what you have done

Technical glitches happen Technical glitches happen

Have a plan-B

•  Record screencast

•  Do not depend on internet •  Keep your stuff ready in browser

And once you are done

•  Keep your hack live for others to see •  Tell us about your progress

•  Show other hackers what you have done in our fourms/groups

•  Publish your code on github •  Join us and take it even further!

Lets have a demo
