10. WORKING ASYNCHRONOUSLY:

15. Y’all got some weird branches.

18. Keep your branches simple.

19. How GitHub does branching:

20. MASTER
BRANCH

21. Everyone can push, everyone can deploy.

22. Frees up your time from
micromanaging someone else’s code.

23. Master is always deployable.

24. Master is always deployable. We deploy
10-40 times a day.

25. If you’re nervous, deploy to staging.
Or deploy a branch. Or deploy to a subset
of our production boxes.

CHECK TWITTER, SEE IF YOU BONED A DEPLOY

26. Keep your branches simple.

PULL REQUESTS:
YOU DON’T NEED
TO FORK ANYTHING.

41. 4
WHY PULL REQUESTS ARE RAD:
REASONS

42. WHY PULL REQUESTS ARE RAD: ASYNCHRONOUS
No meetings.

43. WHY PULL REQUESTS ARE RAD: NOTIFICATIONS
Email is your interface.

44. WHY PULL REQUESTS ARE RAD: ACCESSIBLE
Designers can evolve mockups
and entire workflows.
Non-technical staff can add
their two cents.

45. WHY PULL REQUESTS ARE RAD: HISTORICAL
Pull Requests can be experiments.
Try something out, throw it
away, retain a history.

46. GitHub’s Pull Requests

47. Realtime™ status.github.com real-time polling
git (ssh): true
git (http): true
git (git://): true SUDDENLY,
downloads: true

PULL REQUESTS ARE CHEAP AS HELL
DON’T BE AFRAID TO TOSS IT ALL AWAY

51. Don’t be afraid to
try to (gently) break GitHub.
{ 8 months,
couple hundred commits,
dozens of mockups

52. Pull Requests are
about getting shit done
without wasting a lot of time.

53. Can your workflow be improved?
Do you really need all that process?

58. Can you survive on

@hotdogsladies
on email priorities :

62. “ A priority is observed, not
manufactured or assigned.
Otherwise, it's necessarily not
a priority.

63. “ Making something a BIG RED TOP TOP
BIG HIGHEST #1 PRIORITY changes
nothing but text styling.
If it were really important, it'd
already be done. Period.

64. PRIORITIES ESTIMATES
ASSIGNEES DEADLINES

65. Resist adding meta-work. It gets in
the way of doing real work. (The real
work will get done anyway.)

66. 3We use Issues for three things.

67. shit, something is broken

68. hey, this could be cool

69. todo lists

70. Do you need more than that?
Think about it.
Most of the time, you don’t.
