Hacking For Innovation Delhi

  1. 1. Hacking 101 Christian Heilmann | | Delhi, India, University Hack Day, January 2009
  2. 2. नम#$ Namaste
  3. 3. I’m Chris, hacker and geek.
  4. 4. I am today here to introduce you to what hacking means to us.
  5. 5. To me it means: “Altering a system to do what you want it to do using what is at your disposal.”
  6. 6. It also means having a lot of fun trying to make things do what they weren’t made for.
  7. 7. It is unrestrained innovation.
  8. 8. So welcome, innovators!
  9. 9. We want you to show us what can be built using the systems we (and others) offer...
  10. 10. ...that makes a difference in your lives and make the things you care about easier to achieve.
  11. 11. Find something that always annoyed you with systems you use...
  12. 12. ...and build a workaround.
  13. 13. You’ll be amazed about the impact this can have.
  14. 14. To reach hackvana you need three things:
  15. 15. Access, Data and an Interface.
  16. 16. Access is granted to you via feeds, web services and SDKs.
  17. 17. Feeds are data in a predictable format, for example RSS.
  18. 18.
  19. 19.
  20. 20. Web services are quite similar, only they allow you to filter down the data you want.

  22. 22. ... lots more...
  23. 23.
  24. 24. They also allow you to get the data in other formats to easily re-use it.
  25. 25. 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.
  26. 26. This is dead easy these days!
  27. 27. There’s Yahoo Pipes for mixing, filtering and matching.
  28. 28.
  29. 29. Or if you like SQL-style data conversion there’s YQL:
  30. 30.
  31. 31. Both of these systems allow you to reach data from Yahoo and other services and pre- filter it for use in your own hacks.
  32. 32. Data however is not enough.
  33. 33. Building *working* web interfaces is a specialist skill.
  34. 34. 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.
  35. 35. The technologies are easy enough: HTML for structure CSS for presentation JavaScript for behaviour
  36. 36. Where it gets truly annoying is the unknowns.
  37. 37. You have no idea about the user’s setup, ability or rights to change their technical environment.
  38. 38. And then there are the browsers and all their wonderful bugs and quirks.
  39. 39. This is why it is a good start to use libraries or frameworks.
  40. 40. Here are our helpers: YUI BluePrint
  41. 41. Using these, you can quickly build interfaces that work on the web and mobiles.
  42. 42. What about reach?
  43. 43. The newest way of access that systems and companies allow you these days is opening up their address books.
  44. 44.
  45. 45. Instead of building it and waiting till people come, build where the people are.
  46. 46.
  47. 47. And build with what they use already.
  48. 48.
  49. 49. How about some hack examples?
  50. 50. I use SlideShare – a lot.
  51. 51.
  52. 52. One cool thing is that SlideShare automatically creates transcripts of your slides:
  53. 53. So I’ve used this to create a version that is easily accessible for blind people or those who don’t have Flash.
  54. 54. presentation
  55. 55. Using YQL, it was also easy to write a JavaScript wrapper that allows you to show the transcripts with your slides.

  57. 57. I use Twitter – a lot.
  58. 58. I got all this emails from Twitter telling me about people following me.
  59. 59. What I didn’t get was it telling me when people left me.
  60. 60. Or what I was telling the world before they left me.
  61. 61. So I dug into the API a bit and built
  62. 62.
  63. 63. I put it up, and started testing edge cases.
  64. 64. One of them was Guy Kawasaki, whom I knew has a lot of followers and updates.
  65. 65. One of them was Guy Kawasaki, whom I knew has a lot of followers and updates.
  66. 66. And that started a landslide of visitors, comments and ideas for it.
  67. 67. Tim O'Reilly Guy Kawasaki Ryan Carson
  68. 68. And without knowing it, I became a startup to watch!
  69. 69. What about reach? That was me, time for you to show what you can do!
  70. 70. Innovation is not a matter of skill or being in the right job position.
  71. 71. It is a matter of wanting to change what we have and be ready to play.
  72. 72. We do this to help you see your potential.
  73. 73. And we do this to see if we do a good job in explaining our offers to the developer world.
  74. 74. The web is yours, go out and play!
  75. 75. THANKS! Access happens on several channels.
