DebConf 10: Last day and retrospective

with 4 comments

DebConf continued until Saturday, but Friday the 6th was my last day as I left New York that evening. I’m a bit late in getting this summary written up.

Making Debian Rule, Again (Margarita Manterola)

Marga took a bold look at the challenges facing Debian today. She says that Debian is perceived to be less innovative, out of date, difficult to use, and shrinking as a community. She called out Ubuntu as the “elephant in the room”, which is “‘taking away’ from Debian.” She insists that she is not opposed to Ubuntu, but that nonetheless Ubuntu is to some extent displacing Debian as a focal point for newcomers (both users and contributors).

Marga points out that Debian’s work is still meaningful, because many users still prefer Debian, and it is perceived to be of higher quality, as well as being the essential basis for derivatives like Ubuntu.

She conducted a survey (about 40 respondents) to ask what Debian’s problems are, and grouped them into categories like “motivation” and “communication” (tied for the #1 spot), “visibility” (#3, meaning public awareness and perception of Debian) and so on. She went on to make some suggestions about how to address these problems.

On the topic of communication, she proposed changing Debian culture by:

  • Spreading positive messages, celebrating success
  • Thanking contributors for their work
  • Avoiding escalation by staying away from email and IRC when angry
  • Treating every contributor with respect, “no matter how wrong they are”

This stimulated a lot of discussion, and most of the remaining time was taken up by comments from the audience. The video has been published, and offers a lot of insight into how Debian developers perceive each other and the project. She also made suggestions for the problems of visibility and motivation. These are crucial issues for Debian devotees to be considering, and I applaud Marga for her fortitude in drawing attention to them. This session was one of the highlights of this DebConf, and catalyzed a lot of discussion of vital issues in Debian.

Following her talk, there was a further discussion in the hallway which included many of the people who commented during the session, mostly about how to deal with problematic behavior in Debian. Although I agreed with much of what was said, I found it a bit painful to watch, because (ironically) this discussion displayed several of the characteristic “people problems” that Debian seems to have:

  • Many people had opinions, and although they agreed on many things, agreement was rarely expressed openly. Sometimes it helps a lot to simply say “I agree with you” and leave it at that. Lending support, rather than adding a new voice, helps to build consensus.
  • People waited for their turn to talk rather than listening to the person speaking, so the discussion didn’t build momentum toward a conclusion.
  • The conversation got louder and more dense over time, making it difficult to enter. It wasn’t argumentative; it was simply loud and fast-paced. This drowned out people who weren’t as vocal or willful.
  • Even where agreement was apparent, there was often no clear action agreed. No one had responsibility for changing the situation.

These same patterns are easily observed on Debian mailing lists for the past 10+ years. I exhibited them myself when I was active on these lists. This kind of cultural norm, once established, is difficult to intentionally change. It requires a fairly radical approach, which will inevitably mean coping with loss. In the case of a community, this can mean losing volunteer contributors cannot let go of this norm, and that is an emotionally difficult experience. However, it is nonetheless necessary to move forward, and I think that Debian as a community is capable of moving beyond it.

Juxtaposition

Given my history with both Debian and Ubuntu, I couldn’t help but take a comparative view of some of this. These problems are not new to Debian, and indeed they inspired many of the key decisions we made when founding the Ubuntu project in 2004. We particularly wanted to foster a culture which was supportive, encouraging and welcoming to potential contributors, something Debian has struggled with. Ubuntu has been, quite deliberately, an experiment in finding solutions to problems such as these. We’ve learned a lot from this experiment, and I’ve always hoped that this would help to find solutions for Debian as well.

Unfortunately, I don’t think Debian has benefited from these Ubuntu experiments as much as we might have hoped. A common example of this is the Ubuntu Code of Conduct. The idea of a project code of conduct predates Ubuntu, of course, but we did help to popularize it within the free software community, and this is now a common (and successful) practice used by many free software projects. The idea of behavioral standards for Debian has been raised in various forms for years now, but never seems to get traction. Hearing people talk about it at DebConf, it sometimes seemed almost as if the idea was dismissed out of hand because it was too closely associated with Ubuntu.

I learned from Marga’s talk that Enrico Zini drafted a set of Debian Community Guidelines over four years ago in 2006. It is perhaps a bit longand structured, but is basically excellent. Enrico has done a great job of compiling best practices for participating in an open community project. However, his document seems to be purely informational, without any official standing in the Debian project, and Debian community leaders have hesitated to make it something more.

Perhaps Ubuntu leaders (myself included) could have done more to nurture these ideas in Debian. At least in my experience, though, I found that my affiliation with Ubuntu almost immediately labeled me an “outsider” in Debian, even when I was still active as a developer, and this made it very difficult to make such proposals. Perhaps this is because Debian is proud of its independence, and does not want to be unduly influenced by external forces. Perhaps the initial “growing pains” of the Debian/Ubuntu relationship got in the way. Nonetheless, I think that Debian could be stronger by learning from Ubuntu, just as Ubuntu has learned so much from Debian.

Closing thoughts

I enjoyed this DebConf very much. This was the first DebConf to be hosted in the US, and there were many familiar faces that I hadn’t seen in some time. Columbia University offered an excellent location, and the presentation content was thought-provoking. There seemed to be a positive attitude toward Ubuntu, which was very good to see. Although there is always more work to do, it feels like we’re making progress in improving cooperation between Debian and Ubuntu.

I was a bit sad to leave, but was fortunate enough to meet up with Debian folk during my subsequent stay in the Boston area as well. It felt good to reconnect with this circle of friends again, and I hope to see you again soon.

Looking forward to next year’s DebConf in Bosnia

DebConf 10: Day 3

with 3 comments

How We Can Be the Silver Lining of the Cloud (Eben Moglen)

Eben’s talk was on the same topic as his Internet Society talk in February, which I had downloaded and watched some time ago. He challenges the free software community to develop the software to power the “freedom box”, a small, efficient and inexpensive personal server.

Such a system would put users more in control of their online lives, give them better protection for it under the law, and provide a platform for many new federated services.

It sounds like a very interesting project, which I’d like to write more about.

Statistical Machine Learning Analysis of Debian Mailing Lists (Hanna Wallach)

Hanna is bringing together her interests in machine learning and free software by using machine learning techniques to analyze of publicly available data from free software communities. In doing so, she hopes to develop tools for studying the patterns of collaboration, innovation and other behavior in these communities.

Her methodology uses statistical topic models, which infer the topic of a document based on the occurrence of topical words, to group Debian mailing list posts by topic. Her example analyzed posts from the debian-project and debian-women mailing lists, inferring a set of topics and categorizing all of the posts according to which topic(s) were represented in them.

Using this data, she could plot over time the frequency of discussion of each topic, which revealed interesting patterns. The audience quickly zoned in on practical applications for things like flamewar and troll detection.

Debian Derivatives BoF (Matt Zimmerman)

I organized this discussion session to share perspectives on Debian derivatives, in particular how we can improve cooperation between derivatives and Debian itself. The room was a bit hard to find, so attendance was relatively small, but this turned out to be a plus. With a smaller group, we were able to get acquainted with each other, and everyone participated.

Unsurprisingly, there were many more representatives from Ubuntu than other derivatives, and I was concerned that Ubuntu would dominate the discussion. It did, but I tried to draw out perspectives from other derivatives where possible.

On the whole, the tone was positive and constructive. This may be due in part to people self-selecting for the BoF, but I think there is a lot of genuine goodwill between Debian and Ubuntu.

Stefano Zacchiroli took notes in Gobby during the session, which I expect he will post somewhere public when he has a chance.

DebConf 10: Day 2

with 7 comments

Today was the first day of DebConf proper, where all of the sessions were aimed at project participants.

Bits from the DPL (Stefano Zacchiroli)

Stefano delivered an excellent address to the Debian project. As Project Leader, he offered a perspective on how far Debian has come, raised some of the key questions facing Debian today, and challenged the project to move forward and improve in several important ways.

He asked the audience: Is Debian better than other distributions? Is Debian still relevant? Why/how?

Having asked this question on identi.ca and Twitter recently, he presented a summary. There was a fairly standard list of technical concerns, but also:

  • A focus on quality, as defined by Debian’s highly modular approach. Each package maintainer is an expert on the software they package, and Debian as a whole offers a superior repository of packages.
  • The principles of software freedom, as embodied in Debian’s Social Contract. The Debian community’s current interpretation is a purist one, and Stefano cited the elimination of non-free firmware as a milestone in the upcoming Squeeze release. I wonder, though, how many of the audience, tapping away on WiFi-connected laptops, were able to do so without such firmware.
  • The project’s independent status, supported by donations and volunteers, which empowers it to make its own decisions, free of external impositions.
  • Debian’s ability to make decisions, as embodied in the constitution. This happens mostly through do-ocracy (individuals are empowered to decide questions concerning their own work), though larger scope issues are decided democratically. This one evoked a bit of a chuckle, as decision making in Debian is not always perceived as fully effective.

He pointed out some areas which we would like to see improve, including:

  • Developers accepting shared responsibility for the release as a whole. Making one’s own packages ready for release is necessary, but not sufficient. He cited evidence that the culture around NMUs is changing: historically, due to the do-ocratic system mentioned above, Debian developers have been somewhat territorial about their packages, and non-maintainer uploads were seen as stepping on their toes. However, recent experiments have indicated that this may no longer be the case, and Stefano encouraged more developers to help each other through NMUs.
  • When making decisions, we should seek consensus, not unanimity. In a project with thousands of contributors, whose operations are open to the public, there will never be unanimous support for a proposal, and seeking unanimity leads to stalled decisions.
  • In order to gain more contributors, Debian needs to welcome new and inexperienced contributors, as well as users (who can grow into contributors. He suggested reaching out to derivatives to find more of both. He decried the conventional wisdom that a “thick skin” should be a prerequisite for joining the project, pointing out that this attitude simply leads to fewer contributors. This point was met with applause by the DebConf audience.

All in all, I thought this was an accurate, timely and inspirational message for the project, and the talk is worth watching for any current or prospective contributor to Debian.

Debian Policy BoF (Russ Albery)

Russ facilitated a discussion about the Debian policy document itself and the process for managing it. He has recently put in a lot of time working on the backlog (down from 160+ to 120), but this is not sustainable for him, and help is needed.

There was a wide-ranging discussion of possible improvements including:

  • Editing the policy manual so that it is more readable start to finish as a document, rather than a reference
  • Creating a closer linkage between lintian and the policy manual, so that best practices from lintian get documented, and policy changes are accompanied by new checks
  • Separating the normative and informative parts of the policy manual

There was also some discussion in passing of the long-standing confusion (presumably among people new to the project) with regard to how policy is established. In Debian, best practices are first implemented in packages, then documented in policy (not the reverse). Sometimes, improvements are suggested at the policy level, when they need to start elsewhere. I’m not very familiar with how the policy manual is maintained at present, but listening to the discussion, it sounded like it might help to extend the process to include the implementation stage. This would allow standards improvements to be tracked all the way through from concept, to implementation, to documentation.

The Java Packaging Nightmare (Torsten Werner)

Torsten described the current state of Java packaging in Debian and the general problems involved, including licensing issues, build system challenges (e.g. maven) and dependency management. His slides were information-dense, so I didn’t take a lot of notes.

His presentation inspired a lively discussion about why upstream developers of Java applications and libraries often do not engage with Debian. Suggested reasons included:

  • They are not interested in Linux as a target platform
  • Although their code is released under a free license, they are not interested in meeting Debian standards for freedom and license correctness
  • They use Java because it is cross-platform, and so do not want to concern themselves with platform-specific issues
  • Because Java applications are easy to download and run manually, they perceive relatively little value in the Debian packaging system

Collaboration between Ubuntu and Debian (Jorge Castro)

Jorge talked about the connections between Debian and Ubuntu, how people in the projects perceive each other, and how to foster good relationships between developers.

He talked about past efforts to quantify collaboration between the projects, but the focus is now on building personal relationships. There were many good questions and comments afterward, and I’m looking forward to the Debian derivatives BoF session tomorrow to get into more detail.

Tonight is the traditional wine and cheese party. When this tradition started, I was one of just a handful of people in a room with some cheese and paper plates, but it’s now a large social gathering with contributions of cheese and wine from around the world. I’m looking forward to it.

DebConf 10: Day 1

with 2 comments

This week, I am attending DebConf 10 at Columbia University in New York.

The first day of DebConf is known as Debian Day. While most of DebConf is for the benefit of people involved in Debian itself, Debian Day is aimed at a wider audience, and invites the public to learn about, and interact with, the Debian project.

These are the talks I attended.

Debian Day Opening Plenary (Gabriella Coleman, Hans-Christoph Steiner)

Hans-Christoph discussed Debian and free software from a big picture perspective: why software freedom matters, challenging the producer/consumer dichotomy, how the Debian ecosystem hangs together, and so on.

Steps to adopting F/OSS in government (Andy Oram)

Andy discussed FLOSS adoption in governments, drawing on examples from Peru, the city of Munich, the state of Massachusetts. He covered the reasons why this is valuable, the relationship between government transparency and software freedom, and practical advice for successful adoption and deployment.”

Pedagogical Freedom (panel, Jonah Bossewitch et al)

The panelists discussed the use of technology in education, especially free software, some of the parallels between free software and education, and what these communities could learn from each other. This is a promising topic, though the perspectives seemed to be mostly from the education realm. There is much to be learned on both sides.

Google Summer of Code 2010 at Debian (Obey Arthur Liu)

This talk covered the student projects for this year’s Summer of Code. Most of the students were in attendance, and presented their own work. They ranged from more specialized projects like the Hurd installer, to core infrastructure improvements like multi-arch in APT.

Beyond Sharing: Open Source Design (Mushon Zer-Aviv)

Mushon gave an excellent talk on open design. This is a subject I’ve thought quite a bit about, and Asheesh validated many of my conclusions from a different angle. I’ve added a new post to my todo list to go into more detail on this subject.

Some points from his talk which resonated with me:

  • When collaborating on code, everyone must reason with one collaborator: the computer. This forces a level playing field and a common encoding.
  • Collaborating on other types of creative work is more difficult in part because of the differences encoding/decoding information between different individuals
  • Making this easier for design work requires improving motivational factors and language as well as tools and processes
  • Many design decisions are actually rational, and are compatible with a group consensus project. Too often, I hear that design can’t be done collaboratively, citing “too many cooks in the kitchen” analogies, but I have never believed it.
  • Mushon’s own project, shiftspace.org, seems to be a browser-plugin-based system for collaboratively remixing web applications. I haven’t looked at it yet.
  • Leadership and openness are not mutually exclusive. This is another pet peeve of mine, and there are so many examples of open leadership in the free software community that I don’t see how anyone can think otherwise.
  • Mushon’s presentation is available in revision control so that it can be freely used and improved

How Government can Foster Freedom in Technology (Hon. Gale Brewer)

Councillor Brewer paid a visit to DebConf to tell us about the work she is doing on the city council to promote better government through technology.

Brewer seems to be a strong advocate of open data, saying essentially that all government data should be public. She summarized a bill to mandate that New York City government data be public, shared in raw form using open standards, and kept up to date. It sounded like a very strong move which would encourage third party innovation around the data.

She also discussed the need for greater access to computers and Internet connectivity, particularly in educational settings, and a desire to to have all public hearings and meetings shared online.

Why is GNU/Linux Like a Player Piano? (Jon Anderson Hall, Esq.)

Jon is a very engaging speaker. He drew parallels between the development of player pianos, reproducing pianos, reed organs, pipe organs…and free software. He even tied in Hedi Lamarr’s work which led to spread spectrum wireless technology. To be quite honest, I did not find that these analogies taught me much about either free software or player pianos, but nonetheless, I couldn’t help but take an interest in what he was saying and how he presented it.

DebConf Opening Plenary (Gabriella Coleman)

Biella and company explained all the ins and outs of the event: where to go, what to do (and not do), and most importantly, whom to thank for all of it. Now in its 11th year, DebConf is an impressively well-run conference.

I’m looking forward to the rest of the week!
