    • Hacking 101 Christian Heilmann | http://wait-till-i.com | http://scriptingenabled.org Delhi, India, University Hack Day, January 2009
    • नम#$ Namaste
    • I’m Chris, hacker and geek.
    • I am today here to introduce you to what hacking means to us.
    • To me it means: “Altering a system to do what you want it to do using what is at your disposal.”
    • It also means having a lot of fun trying to make things do what they weren’t made for.
    • It is unrestrained innovation.
    • So welcome, innovators!
    • We want you to show us what can be built using the systems we (and others) offer...
    • ...that makes a difference in your lives and make the things you care about easier to achieve.
    • Find something that always annoyed you with systems you use...
    • ...and build a workaround.
    • You’ll be amazed about the impact this can have.
    • To reach hackvana you need three things:
    • Access, Data and an Interface.
    • Access is granted to you via feeds, web services and SDKs.
    • Feeds are data in a predictable format, for example RSS.
    • http://www.guardian.co.uk/travel/restaurants
    • http://www.guardian.co.uk/travel/restaurants/rss
    • Web services are quite similar, only they allow you to filter down the data you want.
    • http:// answers.yahooapis.com/ AnswersService/V1/ questionSearch? query=delhi+puppies &region=in&lang=en& appid=yahoodemo
    • ... lots more...
    • http://developer.yahoo.com/answers/V1/questionSearch.html
    • They also allow you to get the data in other formats to easily re-use it.
    • The idea of hacking is to use this data, mix it up with other ideas and other data to provide a better service for the end user.
    • This is dead easy these days!
    • There’s Yahoo Pipes for mixing, filtering and matching.
    • http://pipes.yahoo.com
    • Or if you like SQL-style data conversion there’s YQL:
    • http://developer.yahoo.com/yql/console/
    • Both of these systems allow you to reach data from Yahoo and other services and pre- filter it for use in your own hacks.
    • Data however is not enough.
    • Building *working* web interfaces is a specialist skill.
    • I’ve been developing for the web for 12 years and it still is a mystery to me why some things just don’t work.
    • The technologies are easy enough: HTML for structure CSS for presentation JavaScript for behaviour
    • Where it gets truly annoying is the unknowns.
    • You have no idea about the user’s setup, ability or rights to change their technical environment.
    • And then there are the browsers and all their wonderful bugs and quirks.
    • This is why it is a good start to use libraries or frameworks.
    • Here are our helpers: YUI BluePrint http://developer.yahoo.com/yui/ http://mobile.yahoo.com/developers
    • Using these, you can quickly build interfaces that work on the web and mobiles.
    • What about reach?
    • The newest way of access that systems and companies allow you these days is opening up their address books.
    • http://developer.yahoo.com/social/socialdir/ http://code.google.com/apis/opensocial/ http://developers.facebook.com/connect.php
    • Instead of building it and waiting till people come, build where the people are.
    • http://developer.yahoo.com/yap/
    • And build with what they use already.
    • http://developer.yahoo.com/search/boss/
    • How about some hack examples?
    • I use SlideShare – a lot.
    • http://www.slideshare.net/cheilmann/slideshows
    • One cool thing is that SlideShare automatically creates transcripts of your slides:
    • So I’ve used this to create a version that is easily accessible for blind people or those who don’t have Flash.
    • http://icant.co.uk/easy-slideshare/?slides=http:// www.slideshare.net/cheilmann/playing-with-the-web- presentation
    • Using YQL, it was also easy to write a JavaScript wrapper that allows you to show the transcripts with your slides.
    • http://www.wait-till-i.com/2009/01/11/adding-transcripts-to- presentations-embedded-from-slideshare-using-yql/
    • I use Twitter – a lot.
    • I got all this emails from Twitter telling me about people following me.
    • What I didn’t get was it telling me when people left me.
    • Or what I was telling the world before they left me.
    • So I dug into the API a bit and built TweetEffect.com
    • http://tweeteffect.com/?user=codepo8
    • I put it up, and started testing edge cases.
    • One of them was Guy Kawasaki, whom I knew has a lot of followers and updates.
    • One of them was Guy Kawasaki, whom I knew has a lot of followers and updates.
    • And that started a landslide of visitors, comments and ideas for it.
    • Tim O'Reilly Guy Kawasaki Ryan Carson
    • And without knowing it, I became a startup to watch!
    • What about reach? That was me, time for you to show what you can do!
    • Innovation is not a matter of skill or being in the right job position.
    • It is a matter of wanting to change what we have and be ready to play.
    • We do this to help you see your potential.
    • And we do this to see if we do a good job in explaining our offers to the developer world.
    • The web is yours, go out and play!
    • THANKS! Access happens on several channels. http://www.flickr.com/photos/nez/378349478/
