Continuous Documentation - This Best Time is Now - Kenigbolo Meya Stephen, BCaster OY
Bad or non existent documentations are almost always the ripple effect of not writing documentation when it matters. In this talk I’ll take a quick deep dive into the importance of “Continuous Documentation” and how this is important for creating an amazing developer experience.

The importance of documentation cannot be over emphasised. In todays world where we have several buzz words with the suffix “continuous” e.g. “Continuous Integration”, “Continuous Deployment” etc. I believe it is imperative to introduce the audience to the concept of “Continuous Documentation”. Having encountered a documentation bottleneck at my current role as an Engineering Team Lead I coined the phrase “Continuous Documentation” which in plain language means the “Continuous writing and improvement of documentation along with development” hence the phrase “the best time to write the docs is now”.

Seven Hard Truths about Open Source Community - Karen Chu & Matt Butcher, Microsoft
In OSS, managing a project may not get easier as it gets more successful. We like to think that attracting lots of users means success, & success means spreading the workload. But sometimes managing a successful OSS project actually comes with unexpected work. In this talk, we cover hard lessons learned from managing OSS projects:

1.More than code needs to be open–ex. using HackMD, not Google Docs (some countries can't access Google -- this is a roadblock to openness)
2.Multiple projects, same team–one team managing many projects has its own pros/cons
3.Bad actors in the space - how to deal with them
4.Open decision making is part of OSS–making trade offs w/ time, resources & features
5.Branding is more important expected–Devs care that your website is pretty+logo is hip
6.Success=criticism–Pioneering a new space means early benefits but critics catch up
7.Pick sustainable tooling–Freemium/limited tools can cause churn in projects. What happens when you’ve used up your free allotment?

Open Source Contributing Beyond the Code - Rebecca Pilcher, Drupal Association (former) PagerDuty (current)
Great code sells itself, right? Well….
Marketing is essential to every product - especially if your core competition are multibillion dollar companies. So how do you market open source - a product (yes, it’s a product) that might not have a company backing its strategy, and in most cases has very tight budgets?

Working with the Drupal community, Rebecca organized a global open source marketing initiative that created a format for collaboration among a not-so-obvious part of the open source community - the marketers - working across competition and continents to ensure a united and consistent brand.

She’ll share how a successful open source project has structured the collaborative format for marketers to participate, creating a world-wide marketing effort on a shoe-string budget. Rebecca will share how it keeps moving, what's working really well, and where there are potential pitfalls - so that other projects might benefit from what’s been accomplished and where they’ve gone wrong.

Mentors Make Mentors: 7 Tips For Your Open Source Mentoring - Karsten Wade, Red Hat
If mentoring is the cornerstone of a successful open source project, how do you sustainably grow mentors? After all, mentors don't fall from trees, right? How can the hand-holding become viral? In this talk you'll learn why and how "mentors make more mentors" is a secret ingredient of the best open source project.

This mentoring method helps enable collaboration at a scale, to grow beyond a tightly-knit original contributor core. Karsten draws upon two decades in roles across open source projects and as a community architect at Red Hat to craft 7 specific tips for education and discussion. By no means all the tips and tricks one can know about, he focuses on broadly useful areas, such as: defining the role; empowering subjects; creating communities of practice; building diversity in from the start; and more!

By the end of this presentation you will have methods and resources to use for your open source community development mentoring.

(How to) Be a Good Citizen in Open-Source Documentation - Robert Kratky, Red Hat
Open-source projects struggle with documentation -- it is often cited as the weak spot of open source. Many projects have failed to attract docs contributors, and many companies that contribute code don’t have processes for working with upstream docs. How can you, both as a corporate and individual contributor, help to create a healthy documentation set? What are best practices for writing and maintaining open docs?

This session will introduce attendees to basic principles of fitting docs work into the open-source collaboration model. You will learn about open-source documentation what you may already know about open-source code: how to be a good community member, how to contribute meaningfully, and how to ensure the resulting docs serve the community well and can also be downstreamed easily.

Free and Open: A Historical Perspective - Gordon Haff, Red Hat
Software freedom. Open source development approaches. Commercial business models that incorporate open source software in some fashion. These interrelated threads have always had points of conflict and that has never been truer than in today’s cloud era.

In this talk, Red Hat’s Gordon Haff will take you on a tour through how conflicting notions of ownership, cooperation, shared commons, and profit has played out since the early days of software and before. But this won’t be just a history lesson. There are today real and serious questions about what it means to have commercial software businesses that can thrive in a world of mega-scale public cloud providers delivering software in a far different manner than the world in which free and open source software was originally conceived.

Does open source mean something different today? Should it?

BoF: Launching Projects and Foundations at Scale - A Product Approach - Michael Cheng, Facebook & Max Sills, Google
As new companies and industries continue to embrace building home-grown software development teams, open source has also been brought into the mainstream as an indispensable part of any software organization. For better or worse, open source is now run in much more polished and professional manner -- much in the same way that products are built. In this talk, Max Sills and Michael Cheng from the Open Source Teams at Google and Facebook will talk about some of the lessons learned from scaling an OSPO to handle hundreds of open source project releases a year as well as the lifecycle involved in transition projects into successful foundations.

BoF: Securing Open-source: Dependencies, Incident Response, Vulnerabilities, and Bug Bounties - Maya Kaczorowski, Google
Open-source projects have a more nebulous operating model, and that also means it's harder to figure out who's on the hook when something goes wrong.

In security, if you're running an open-source project that's widely used, that means the community looks to you for help identifying and addressing vulnerabilities. We'll discuss what a mature open-source project does for security, including:
- mapping and understanding dependencies, and frequently patching those,
- responding to incidents in a private manner, and managing disclosures,
- patching vulnerabilities and vulnerability management, and
- running a bug bounty program.

Altogether, these make up a complete security response program for a larger open-source project. We'll also discuss what to do first if your project is just getting started, what to prioritize with limited resources (that's every project!), and what smaller projects can do when all of these pieces aren't possible.

Growing and Sustaining OSS: Evolution of the Ceph Development Process - Neha Ojha, Red Hat
Ceph is a fully open source distributed storage system that started in a university lab, and has now reached 100K commits from nearly 800 contributors from all over the world. The use cases for Ceph are broad; from providing shared file systems in small private clusters, Ceph scales to meet the needs of even modern public clouds. Like other large OSS projects, a diverse set of tools and procedures have grown up around the user and development community.

This talk will explore the unique aspects of the size and scope of Ceph development process, and how the community is trying to improve the overall experience through documentation. The nature of many large software projects means documentation and reality are often drifting further apart, and this is especially true for projects like Ceph that are constantly evolving to meet the needs of new hardware systems and operating environments.

How Did Automotive Grade Linux become THE Open Source Community Cars? - Walt Miner, The Linux Foundation
Car companies and their suppliers long ago learned how to take raw steel and turn it into a finished product. When software first entered the car, it was all closed source, but at the turn of the twenty-first century the complexity of software in cars exploded. Even so, OEMs and Tier Ones continued to keep their software proprietary, so much so that most Tier Ones only reluctantly gave source code to their OEM customers. With consumers now demanding the same app based experience their car that they have on their mobile phones and tablets OEMs have turned to open source software to make up the gap. How did the ultra-competitive world of car manufacturers come to together to embrace Automotive Grade Linux and grow a community where Tier One suppliers, OEMs, and hobbyists can come together and build software for your next car? Walt reviews the challenges that were overcome, where we stand today, and what needs to be done to continue to grow the open source automotive community.

Sourcelift and How We Care about Open Source - Jona Azizaj, Kiwi.com
It’s only been a couple of years since Kiwi.com was a small and bootstrapped startup. Kiwi.com job would have been immensely more difficult if it wasn’t for the open source community and all the tools they provide and share with everyone. Now they feel the urge to give back to the community, not only with code commits but also with the recent project they have started that is called Sourcelift. SourceLift is a project created by Kiwi.com to help bring communities together. By providing flights, they hope to boost the progress of FOSS projects while rewarding tireless contributors with a well-deserved trip at the same time.

In this talk, Jona will share why and how Kiwi.com help open source projects, Sourcelift and the internal tools they have open sourced.

Community Managers Surviving the Shift from Non-profit to For-profit Projects - Stefano Maffulli, Scality
What are key differences between foundation-based and company-led open source projects? What skills, tools, metrics do community managers need in non-profit and for-profit projects? What drives the motivation of contributors?

Open source projects hosted at foundations typically involve dozens of member companies with hundreds (and sometimes thousands) of developers. Company-led open source projects on the other hand, typically involve majority of developers employed by the “host” company with a small number of volunteers from a wider community.

Based on experience working at non-profit FSFE, OpenStack and at for-profit companies Funambol, Scality this presentation will share lessons learned. The talk will include different approaches they had to learn for motivating community members, doing outreach to potential contributors, dealing with cultural differences (incl. open source background), looking at community metrics, etc.

Building Diverse Blockchain Communities for a Decentralized Future - Jocelyn Matthews, Storj Labs
New communities are forming around blockchain and decentralization technologies. To realize the full potential of this technology, we need women and people of color to be involved in its creation and its ability to provide economic empowerment. This presentation will discuss the confluence of blockchain and open source and how its principles of transparency, openness will contribute to societal shifts for women and p.o.c. in coming years.

Decentralization and blockchain technologies apply the principles of open, transparent collaboration to our burgeoning world of opportunity, suggesting blockchain technology to be on the forefront of equality, empowerment and inclusiveness. But we can't be passive in this expectation; if we expect blockchain technologies to take hold and truly be successful, we must inspire a diverse spectrum to get involved in these communities to help build the tech of tomorrow.

Catalyzing Industry Collaboration with Open Source - Gaël Blondelle, Eclipse Foundation
In this talk, we describe how the Eclipse Foundation has developed and improved a model for industry collaboration in the open over the past 15 years. Starting in 2012 we have been working with different industry leaders in IoT, Automotive, Aerospace and others to create repeatable and adaptable governance models and processes for very focused and transparent collaboration efforts. We believe about 80% of all the software needed can be developed collaboratively and shared.

While this model is not a silver bullet, we strongly believe that it helps to develop modern stacks at lower cost, to allow faster deployment and enable our ecosystems to compete with bigger and more advanced industry players.

We will present what has worked and what did not work when setting up more than 20 different Working Groups, some of them being led by software companies, while other are created by automotive engineers that are users rather than creators of the technologies.
