Monday, 21 May 12 15

16. GIVE BACK MEMORY

grow and grow...
• Now, we return memory to
the OS
• Part of our performance
improvement strategy
Monday, 21 May 12 16

17. ENC VS ENVIRONMENTS
• You could set the client
environment from the ENC
• The client would ignore you
(sometimes)
• Now it doesn’t
• Bug fix, not feature
• Still great!
Monday, 21 May 12 17

18. PLUGIN SYNC

synced and used successfully

Monday, 21 May 12 18

parameters and properties

VERSION
Bug fix with no other
behavioural or functional

the scope of changes in any
release
Monday, 21 May 12 27

28. SHIPPING CODE FASTER
Monday, 21 May 12 28

Monday, 21 May 12 29

30. MONTH DEVELOPMENT RELEASES

release after Telly (3.0.0)

every month as a preview

changes a year old before
they ship to the community

Monday, 21 May 12 30

31. NOT DONE YET...
Monday, 21 May 12 31

32. OLD MISTAKES STILL HAUNT US
• Parameterized classes don’t
work everywhere
• undef vs nil
• classes with ‘-’ in the name
Monday, 21 May 12 32

33. SLOW MOVING ECOSYSTEM
• Dashboard has not gotten a
lot of love recently
• Puppet Labs modules need
more attention
• ...but we are starting to
invest in them.
Monday, 21 May 12 33

34. BROKEN (OR DELAYED)
PROMISES
• import isn’t deprecated
• The static compiler isn’t the
default
• Facter doesn’t have typed or
structured facts
Monday, 21 May 12 34

35. THE FUTURE
Monday, 21 May 12 35

36. THE ECOSYSTEM
• Shipping structured and
typed facts without the
ecosystem is a no-go
• On release, new features
should work everywhere
Monday, 21 May 12 36

37. THE NEXT CHALLENGE
Waldorf, kicking ass and taking names
Monday, 21 May 12 37

38. EXPERIMENT ONE
We are going to fix some high-voted tickets
Monday, 21 May 12 38

39. VOTES SHAPE THE ROADMAP
• We said votes matter before
• It wasn’t really true
•I don’t expect you to believe
me this time...
• ...so we are gonna fix
tickets, then ask you to
believe us
Monday, 21 May 12 39

40. VOTES SHAPE THE ROADMAP
• We want community input
into the roadmap
• This seems a solid choice
• Success is that votes get
used by the community
• ...and that we use them to
shape the roadmap!
Monday, 21 May 12 40

41. SCHEDULE TRANSPARENCY
Monday, 21 May 12 41

42. REDMINE “ACCEPTED” TICKETS
This is the scrum “unsorted product backlog”
Monday, 21 May 12 42

43. REDMINE “3.X” TARGET VERSION
This is “we might fix it before 4.0.0”
Monday, 21 May 12 43

44. SAME THING!
Monday, 21 May 12 44

45. GONNA FIX THAT UP
• Target open tickets at the
next numeric version
• Means “trying to fix for that
release”
• Stillshipping time-based
product, so things will miss
Monday, 21 May 12 45

46. OTHER EXPERIMENTS
You bring ‘em, We try ‘em
Monday, 21 May 12 46

47. TECH FOR WALDORF
This is all speculative, no promises.
Monday, 21 May 12 47

48. SYSTEM MODULE PATH
• Modules can move fast
• Batteries-included is great
• Combine them!
• Best of both worlds
Monday, 21 May 12 48

49. STATIC COMPILER
• Missed Telly, but only just
• Content reference, not URI
• Single file catalog?
• Easier push model?
Monday, 21 May 12 49

50. STRUCTURED FACTS
• Really, structured and typed
• JSON is the template for
supported types and
structures
• Full ecosystem support
• Third party facts only, initially
Monday, 21 May 12 50

51. BETTER GRAPH PROCESSING
• Improve graph handling in
the Puppet Agent
• Fix the “anchor” pattern
• Improves from O(N^2)
worst case to O(N)
• Allows future improvements
to the catalog and graph
Monday, 21 May 12 51

52. BETTER ENVIRONMENTS
• Different versions of a type
in different environments
• Turns out that is pretty hard
(thanks, Ruby)
• We will make it easy
• Fix performance cost too
Monday, 21 May 12 52

53. CLEANER, DOCUMENTED CODE
• Easier to use Puppet as a
library or extend it
• Better API definitions
• Richer integrations
Monday, 21 May 12 53

54. MY REAL GOAL
Monday, 21 May 12 54

55. BUILD A 10× TEAM
...and let them work with the community to be awesome!
Monday, 21 May 12 55
