Community at Sun Business .Next 2008

Tomorrow I'll be at Sun's Business.Next 2008 Conference in Tokyo. I'll bring my camera, too. John Fowler, executive vice president of Systems, will be doing the main conference keynote, and there will be tracks on Solutions, Technology, and Community.

The Community track will include Takanobu Masuzuki on Sun's Open Source development and business strategy, and Akira Ohsone with a technical presentation of the new OpenSolaris binary distribution ("Project Indiana"). Also, Reiko Saito will talk about community translation and localization issues, and Hisayoshi Kato and Kenji Funasaki will offer the latest technical advances in OpenSolaris. Additionally, there will be sessions on MySQL and Java and a panel on how companies in Japan are using Open Source software. There will be a booth area for demos and conversation about all of Sun's technology as well. If I don't screw up, I'll post some images over the weekend. I hope I don't get lost.

Opening Japan

Matt Asay explores open source in Japan and concludes that it may be time to give the place a second look -- Open source: Made in Japan? Good post. He points to some excellent examples of open source contributors in Japan and also corporate and government use of open source.

I found Matt's blog being discussed on the Tokyo Linux User Group list -- [tlug] "Open source: Made in Japan?" blog -- today where Curt Sampson was talking about the language/culture barriers in Japan and also how Japan is home to more NetBSD developers than any country outside the United States. I didn't know that, but I'm not surprised I didn't know since Japan is a country absolutely determined to down play its role in just about everything possible. It's exactly the opposite behavior of the United States, which tends to over play its hand in just about everything possible.

Anyway, I agree about the language/cultural barriers. They are big. Generally, I find very few in the west interested in software development taking place in Japan, and I also find very little interest here in exploring anything outside of Japan. It goes both ways. It's tough to look inside, and very few here are looking outside. There are obvious exceptions, of course, but I've been quite surprised by the size of the east/west divide for a market so big. See Matt's blog for the exceptions, by the way, which are all very encouraging.

I think similar issues were present in China, as well, but recently when I go to China and visit the universities I find the students much more willing to learn from and engage with the west. They are loud and enthusiastic and bold. I'm no expert on China, and I could be seeing only one part of that market because they have so many students in computer programs now, but it seems to me that the trends are clear and distinction with Japan is now very big. Whereas the language/cultural barriers here in Japan are the same as always (and I can find no one to dispute that), they seem to be going away in China.

Another factor for Japan may be that this market is mature and expensive and suffers from under exposure because massive attention and resources are flying to China and India because those guys are rapidly emerging and sucking up all the publicity. I was also thinking that some of this may be just a mis-understanding since the west and east view "community" and "contribution" and "individual motivation" somewhat differently. Who knows. Some good opinions on the Tlug list, too. Check out the thread.

Also, Matt mentioned Ruby. Very cool community. I was so impressed with the Ruby community a while back. Here are all my blogs on Ruby. And Matt mentions the Japanese government getting involved in open source, too. Well, they are also exploring OpenSolaris (here, here, here). Oh, one more thing: the Japan portal for OpenSolaris is our #1 portal by far in terms of total page views hitting the site. But, man, the Spanish are catching up jet fast! :)

Photo Credits

SD Times used one of my photos from the RubyKaigi2007 in an article (on page 8 of this pdf) recently. The piece is about JRuby's Charles Nutter and Thomas Enebo. Very cool. I remember having a conversation with the guys and a PR firm a while back and giving permission, but I forgot about it. Then a friend sent me the link this morning because he thought the image looked familiar. Sure enough. Looks great in the article layout, too. :)

I publish the vast majority of my images under the Creative Commons Attribution - NonCommercial - ShareAlike license, but, sadly, SD Times didn't give me a photo credit. Oh, well. I'll have to be more explicit next time right up front so there is no misunderstanding. But I'm very happy the photo was used, and I have a lot of respect for SD Times.

However, over the last year or so, I've noticed that a few others have taken my images and used them in blogs and such without asking and without giving credit. Actually, you don't have to ask since they are licensed for that purpose, but to rip off someone's work as your own isn't very cool, eh? I'll continue shooting images and contributing them via CC because I believe that the vast majority of people appreciate it and are contributing back to the photo commons as well.

Leaving Asia Behind?

Interesting article in the reg about cultural issues dividing open source communities. Here's the article (in bold) and my comments spread throughout:


Open source 'leaving Asia behind'
By Bryan Betts
Novell veep warns of collaborative culture clash

The open source community risks leaving Asian users and developers behind,


I think that's probably a bit of an over statement, don't you? It's clear that Asia in general is behind the West in this area, but who the heck is racing? Now that open source has gone mainstream in many Western markets, some of the leaders in some of the communities are starting to sound like this all happened over night (and by implication others are "behind"). It didn't. It took decades even in the supposedly more enlightened West. Also, I bet some Asian communities come up to speed on open source faster than some in the West realize, and I bet these new Asian communities will start to express open source development methodologies in different and interesting ways. So much of the rhetoric from the U.S. and Europe is like this, though. It's patronizing. Many times it's not intended as such, but it is nonetheless.


thanks to cultural differences


This is true. And these differences are nothing short of gigantic -- especially comparing East Asia with the West. And then when you add language to that mix, it only magnifies the challenge. It's huge. However, with some focused effort, these differences can be mitigated to a certain degree. It takes time, though, and you have to want to overcome the problem and find the middle ground. I find a lot of people on both sides generally pretty ignorant about the issue, though. In other words, a lot of people see communication issues as relatively minor, when in reality I think it's so much bigger than anyone realizes. Also, many people on both sides can appear totally genuine, but it's clear that they are oftentimes locked behind cultural and/or language walls -- East or West -- and can't really see the other guy's perspective.


and western business's tendency to treat programmers there as code monkeys rather than software designers, a senior Novell staffer has warned.

Kurt Garloff, the company's global product opportunities veep, said that while open source communities regard criticism as constructive, others see it as insulting. Speaking at the start of the company's Hackweek in Germany, he argued that software companies need to find ways to mitigate the sometimes confrontational nature of open source development, if Asian developers are not to be excluded.


I have many examples of people from Korea, Japan, and China who view the OpenSolaris community as too hostile to engage with. Others here have said the same about some parts of the Linux community in the U.S. Some of this is true, of course, but some of it is an over-reaction as well. So, I'd generally agree with this point. Though I must admit, I've never heard the term "code monkey" before. It doesn't surprise me, though.

But even when you remove obviously bad behavior, the larger -- and much more important -- issue is that some of these cultures simply communicate differently. And very differently at that. It really is that simple. And hard. The West can't expect the East to adopt the open source culture from San Francisco or Portland or somewhere, and the East has to open up to new ways of communicating online as well. There is more than enough room for both sides to move to the center.


"If you look at the open source mailing lists to see where the posts come from, it is almost exclusively white males, from Europe, including Eastern Europe and Russia now, and North America, plus some from South America," he said.


Sure. I agree. But there are other lists here in Asia where various Asian communities communicate quite well. We have to stop thinking about "the open source mailing lists" as one set of lists. There are many sets of lists for many communities and they are spread out all over the world. Also, the implication here is that there is one open source community. There isn't. The open source "community" is actually a community of communities. And although open source types recognize that obvious fact, they don't then factor in open source communities of communities across cultural and language barriers. Also, the very terms "open source" and "free" and "community" may mean something in Boston but I'm not sure it means quite the same thing in Tokyo or Beijing. In fact, I rarely talk about "community" here like I used to talk about it in San Francisco. Concepts change when expressed in different languages. Sometimes dramatically.


"The absence of countries such as Japan is striking.


Why is this striking? It's easily explained, actually, but the statement itself demonstrates a clear lack of knowledge about the Japanese market and culture. Look, some aspects of Japanese business are so utterly closed they make Microsoft look open. No question about it. There is a lot of old and traditional companies here. But guess what: there are a lot of traditionalists in London, New York, Los Angeles and even in the oh-so-too-cool San Francisco Bay Area. Also, I'm starting to get to know some of the guys in the Mozilla, Linux, Ruby, and PostgreSQL communities here in Tokyo, and they are remarkably open even by the artificially imposed Western standards. I still think they can be better connected to the West, but at least some of these communities demonstrate that Japan is not as monolithic as it may appear from the outside. In fact, the Ruby conference here recently literally blew me away and surely ranks right up there with the very best open source conferences I've ever seen. It was clearly a community event. But I've seen the other extreme as well. If you show up in Tokyo or Seoul or Beijing and do some sort of controlled corporate event, then sure, all the cool guys go away or get quiet. This is a predictable as the sun rising, by the way.


"Open feedback is OK culturally in Western Europe but a big problem in Japan - for example, open criticism can be seen there as a big shame on you. I do hope it doesn't keep them on the margins of open source - we are trying to create awareness of these issues."


Yah, that "shame" bit is so overblown. Someone is reading too many old sociality textbooks from the 1950s. Just like the myth of "the Japanese (and Chinese and Koreans) don't ask questions at conferences. These are all generalizations that get in the way of understanding.

Sure, many of the gigantic Japanese companies are conservative and pretty traditional places. But the radicals and innovators are out there, and they are happy to engage. Finding them takes a little effort, though. At Sun, some of the guys here put on a monthly event called Developers' Lounge. At first glance it's just a party, but when you hang out longer you find that it's an amazing communications mechanism. Lots of communities from Tokyo all gather in this little club and drink and eat and swap stories and basically do as series of rapid-fire lightening talks about projects they are working on. Very simple. But every time I go there I have the impression I'm at OSCON or something. No difference. Other than it's in Japanese. And it ends on time, too. :) Ruby gave me this exact same impression.

So, there are clear examples to contradict some of the thoughts in this article, but I think that the scale of the communities in the West are so much larger that we can't even see the guys in the East. In terms of scale, I bet India and China change that. Not in the short term, but over the longer term. Also, the last time I was in China some reporters were asking me how China can contribute to open source. I said I have no clue. Who am I, I thought. You tell me. You know best. The only thing I can say is to learn what the West has done and then express that in a Chinese way and take the concepts to new levels. But don't just follow the Americans or the Europeans because they were first. Do something different with what's already been done and let the West learn from that. And around we go. Seems to me that would be a great contribution. Same goes for Japan. Same for Korea. India. Etc.


He suggested that while Asian cultures are evolving and opening up to constructive criticism, one option for now might be for open source companies to create less free-wheeling and more protected environments for would-be developers to collaborate in.

"The second angle is that the open source community needs to adapt and become less confrontational," he said, adding that the language of on-line discussion can discourage western newcomers as well.


I agree with this. Although I live in Tokyo, I was born in New York and the rhetoric I see in many Western open source communities is a total turn off. This "open constructive criticism" bit is not a license to be obnoxious or rude or to attack people online. Yet I see it every day and people keep saying its ok. It's not.

The previous point, however, I don't agree with at all. The bit about creating "less free-wheeling and more protected environments" and all that. That's so overtly patronizing I can't believe it was even suggested. The West should be less confrontational not to better engage with the East but because it's simply the right thing to do to engage with everyone. And I hope Asian communities reject the idea of being protected. It's silly. Instead, why not try understanding the Asian communities. Why not even try to facilitate the creation of new Asia-specific communities (whatever technology, whatever country) where people interact in their own way, not in some manufactured and protected American or European way. And then why not create connections to those communities, so entire communities can interact via specific people who are bilingual and who understand the cultural differences? This already happens today, by the way.


"In countries such as India and China there's an additional problem," he continued. "Their education system trains them to do software manufacturing - the straightforward but tedious work of implementing specifications - rather than software engineering, and that's how western outsourcers use them.


I'm not sure about India in this case. I've heard otherwise, actually, but I'm not really that aware of the India market. I hope to change that this year, though. However, I think this is probably more true of Japan and China. And it's tough to even compare Japan, Korea, and China due to the differences in scale, language, and culture. I just don't know very much about the universities in these areas, but these points are critical so I'm looking forward to getting involved.


"Software engineering is an art, it's a fundamentally different mindset to software manufacturing."


Ah, yes the "art" bit. Therefore, the implication is, it's better. Perhaps. I'm not convinced. I have heard this from time to time from Japanese and American/European developers and administrators here, but I really have no direct knowledge about it yet.


He added, "I can certainly see people being afraid of the low-cost economies, but the bigger loss is for the whole world, if it doesn't use developers from all cultures to develop code."


I'm not sure what the "afraid of low-cost economies" is all about, but all this makes my life quite interesting right about now.  Fascinating issues. And issues that will not go away any time soon. In fact, as open source engineering and community development methodologies grows into new areas, it will be really interesting to see how new people implement the concepts. It will be just as interesting to see all the new leaders emerge, too ...

RubyKaigi2007

I spent the weekend at RubyKaigi2007 in Tokyo. It was great to see Tim Bray again and also to meet Dave Thomas for the first time. Both Tim and Dave gave excellent presentations, along with Sun JRuby developers Charles Nutter and Thomas Enebo. In fact, Dave got a standing ovation for his conference-closing keynote, which was a beautiful tribute to the Ruby community. He basically thanked the community and talked at length about the community's values and how to protect those values as the community enters into a rapid growth phase. Some nice lessons for us in the OpenSolaris community as we grow as well.

I met dozens of other people from Japan (obviously) and from Europe and the U.S., and I spent a lot of time talking with some great TLUG guys (Zev Blut, Edward Middleton, Alain Hoang) as well. I even met Yukihiro Matsumoto after his opening keynote. Very cool. Overall, I was very impressed with the Ruby community. There is huge diversity there, and the community feels totally authentic. The Japanese presentations seemed creative, and the audience responded enthusiastically to the speakers. And there were a lot of speakers, too! Dozens. How they pulled off so many speakers without a hitch I'll never know. But it just worked. I also loved the IRC screen for live audience conversation during the presentations, and the live IRC translations of the English speakers, too. Very creative.

I took a lot of pictures, and I think they represent the passion I so clearly felt at the conference. This community is young. It's alive. It's dynamic. I had a blast. And thanks, guys. I learned a great deal about the most important thing you are teaching.

Ruby in Tokyo

I'll be at the Ruby conference in Tokyo this weekend (Japanese, English). Tim Bray will be here doing a session, so it will be great to catch up with him as well.

Developer's Lounge

Last night I went to a very nice little gathering of developers in Tokyo -- The Developer's Lounge. I met people from various communities around here, including Linux, Postgres, KDE, NetBeans, Curl, Ruby, OpenSolaris, Java, and a few companies as well. This was my first time, but I hope to go regularly. The really cool thing about it was that many people presented about their projects, those presos were all short with just a few slides or no slides at all, and it was all done in an understated social setting. Lack of formality is oftentimes a nice delivery mechanism for the transmission of information. Good food, good wine, and a little conversation. Works for me. I took some pics, too ...
