60% Active Users are on Mobile
100+ Open Source Projects
14. Open Source Craft
(operating principles)
Use Open
Assume Open
DeïŹne Secret Sauce
Measure Everything
Default to GitHub
Default to Permissive
Acquire and Open
Pay it Forward
15. Use Open
Use and benchmark open source software by
default. When starting a new initiative, always
evaluate open source options before going to
reinvent the wheel. (e.g., if redis doesnât work for
you, you better have solid evidence)
17. Define Secret Sauce
Donât open source anything that represents a core
business value. Define your secret sauce so
thereâs a shared understanding that can guide
decisions. Embed this secret sauce within your
culture and company via training.
21. Assume Open
Assume that what you are developing will be
opened in the future. Pretend the whole world
will be watching. Use reasonable third party
dependencies to prevent pain down the road. (we
mostly use Apacheâs Third Party Guidelines as a
starting point)
22. Default to GitHub
The GitHub community is the largest open source
community, with over three million users. You would
be stupid to ignore that fact. Embrace social
coding tools to lower the barrier to
contribution and participation.
23. Foundations are Good*
We just prefer not to default to them. We view
them as a place for stable projects that grow
into maturity, not to incubate new projects. Our
goal is to gain traction first as fast as possible. If not,
fail fast and carry on.
25. Be Permissive
For outbound open source software, we default to
OSI permissive licenses (the ALv2 in the majority of
cases). We do this so we can maximize adoption
and participation, which we favor instead of
control.
26. Embrace the Trend

27. Notes from Antirez (1)
âFirst of all, open source for me is not a way to contribute to
the free software movement, but to contribute to humanity.
This means a lot of things, for instance I don't care about
what people do with my code, nor if they'll release back
their modiïŹcations. I simply want people to use my
code in one way or the other.
Especially I want people to have fun, learn new stuff, and
make money with my code. For me other people making
money out of something I wrote is not something that I
lost, it is something that I gained.â
See http://antirez.com/news/48
28. Notes from Antirez (2)
1) I'm having a bigger effect in the world if somebody
can pay the bills using my code.
2) If there are N subjects making money with my code,
maybe they will be happy to share some of this money
with me, or will be more willing to hire me.
3) I can be myself one of the subjects making money
with my code, and with other open source software
code.
For all this reasons my license of choice is the BSD
licensed, that is the perfect incarnation of do whatever you
want as a license.â

29. Acquire and Open*
Include open sourcing software in M&A
discussions, especially if youâre mainly acquiring
talent or shelving the product. Thereâs no need for
software to go to waste.
30. Acquire and Open: RedPhone
See https://github.com/WhisperSystems/RedPhone
31. Acquire and Open: Clutch.IO
See http://engineering.twitter.com/2012/10/open-sourcing-clutchio.html
See http://www.prweb.com/releases/2012/10/prweb10067693.htm
32. Measure Everything
If you canât measure what youâre doing, you have
no idea what youâre doing. We measure everything
inside of Twitter (affectionately called birdbrain)
and make it accessible to everyone.
33. Pay it Forward
Support open source organizations and
projects important to your business, itâs the
right and smart thing to do. This can be financially
or simply staffing projects that are strategic to you.
34. Open Source Craft*
Use Open
Assume Open
DeïŹne Secret Sauce
Measure Everything
Default to GitHub
Default to Permissive
Acquire and Open
Pay it Forward

36. Light / Automated Process
Automated Process via JIRA Workflow
Inspiration from Eclipse.orgâs IPZilla
37. Not all process is bad!
âprocess is an embedded reaction to priority stupidityâ
True.
Remember the history of surgery?
Ignaz Semmelweiz (hand washing)
Surgery checklist: Glad your surgeon washes hands?
Even with surgery process, metal objects still are left in people :)
See http://many.corante.com/archives/2003/09/17/process_is_an_embedded_reaction_to_prior_stupidity.php
See http://en.wikipedia.org/wiki/Ignaz_Semmelweis
38. Automate Quality Checklist
Tooling to check for baseline âqualityâ before we open
â README
â LICENSE
â CONTRIBUTING.MD
â .travis.yml
â Avoid KEYS / sensitive bits
â Avoid GPL License Family
Attempts to build and posts results in JIRA.
Enforces and teaches good practices.
39. Automate Sourcing for Hiring
Letâs scale hiring a bit!
Run monthly queries on contributors to our open source
projects and projects of interest.
Hand it off the Recruiting and the ATS.
Itâs hard enough to find good talent, why not hire from open
source projects of interest.
40. Automate Reporting / Metrics
Send out weekly reports based on:
Open Sourced Projects (what opened)
Top Committers (commits+issues closed)
Releases (assumed via git-tag)
Contentious Issues (issues with most comments)
Top Watched Project (most stars)
Top Forked Project (most forks)
Track trends.
Motivates contribution.
41. Conclusion
DeïŹne Your Principles
Open Source Almost Everything
Measure / Automate Everything
