  15. UNIX

  16. UNIX small sharp tools

  20. Heroku as UNIX for developers

  21. Do 1 thing do it well Heroku as UNIX for

    developers
  22. Do 1 thing do it well Straightforward Setup Heroku as

    UNIX for developers
  23. Do 1 thing do it well Straightforward Setup Lower barrier

    to entry Heroku as UNIX for developers
  24. Do 1 thing do it well Straightforward Setup Lower barrier

    to entry
  25. Small functional apps Do 1 thing do it well Straightforward

    Setup Lower barrier to entry
  26. Small functional apps An example (KISSMetrics Data Loader): Do 1

    thing do it well Straightforward Setup Lower barrier to entry
  27. Small functional apps An example (KISSMetrics Data Loader): Open DB

    connection Do 1 thing do it well Straightforward Setup Lower barrier to entry
  28. Small functional apps An example (KISSMetrics Data Loader): Open DB

    connection Run query Do 1 thing do it well Straightforward Setup Lower barrier to entry
  29. Small functional apps An example (KISSMetrics Data Loader): Open DB

    connection Run query Post data Do 1 thing do it well Straightforward Setup Lower barrier to entry
  30. Small functional apps An example (KISSMetrics Data Loader): Open DB

    connection Run query Post data Others: OAuth, Vault, API, Core, Canary, Add-ons, Success, etc. Do 1 thing do it well Straightforward Setup Lower barrier to entry
  31. None
  32. Run and forget

  33. Run and forget Alert me when things break

  34. Do 1 thing do it well Straightforward Setup Lower barrier

    to entry
  35. git clone git://github.com/heroku/... heroku create -s cedar git push heroku

    master Do 1 thing do it well Straightforward Setup Lower barrier to entry
  36. Heroku as UNIX for developers Do 1 thing do it

    well Straightforward Setup Lower barrier to entry

  43. Defined Contract/API Developer environments Environment parity

  44. heroku create -s cedar mystaging-app git remote add staging git@github.com:heroku/...

    git push staging master git push production master Defined Contract/API Developer environments Environment parity
  45. production = staging = dev minimized divergence enables continuous deployment

  65. ownership productivity agility Team Design

  66. ownership productivity agility You choose the tools to get the

    job done, you support the API for others, you own the features to make users happier, you ensure it works, you carry the pager
  67. ownership productivity agility Broad focus around quality, quality comes from

    solid engineering, give time to engineers, less meetings more get shit done
  68. ownership productivity agility Iterate fast and often, a failed attempt

    is a successful experiment, culture around seeing/doing over talking
  69. ownership productivity agility “When can I see it”

  70. ownership productivity agility Iterate fast and often, a failed attempt

    is a successful experiment, culture around seeing/doing over talking
  71. Teams don’t communicate the same way

  72. More than a codebase

  73. Github issues is

  74. Github issues is centralized

  75. Github issues is centralized, is asynchronous,

  76. Github issues is centralized, is asynchronous, hands off ownership

  77. Github issues alone doesn’t fix communication Engineering culture of building

    and sharing

  82. Quality Quality Quality Hire for Quality & Culture

  83. Let them Work Quality Quality Quality

  84. Quality doesn’t work with deadlines Quality Quality Quality
