Report:CLSx Tokyo 2015

It was the first time to hold CLS(Community Leadership Summit)x in Tokyo though it was very fantastic talk while the event.

We’ve talked Japanese Community issues just happened – almost same in U.S. and Europe OSS community and we’ve shared ‘key and knowledge’ for the issues with each other.and we’ve decided to continue to discuss that at next event (CLSx Tokyo #1) near future.

We’ve discussed 5 things in the issue:

1.How to design OSS community.
2.Company and OSS Community
3.The members getting older,geeker thus smaller (and varnished at worst)
4.There are no Leaders in Japanese OSS community why they are not needed?
5.Gamification with girls and ‘moe’

1. is there were some issues already been happened the past.A OSS vendors brought 600US$ to their community to look for the contributors and developers for their OSS but they couldn’t gathered much of them.on the other side there were great developers as volunteers in an OSS community – meant ‘only money’ is not so fascinated ‘money and how to use it’ are important for the community.
(c.f. Japanese OSS community used to feel difficulty to ‘the money’ – not so earn with OSS but lately there are ton of OSS solutions released by Japanese IT vendors,we move the mind and have to earn with OSS – now OSS is ‘free from money’ is old word :))

2.has many issues,almost Japanese OSS Community is rooted to the companies because almost of they have got started as ‘XXX Users Group’ managed by companies.In U.S and Europe OSS is important business – NPO and companies Linux or OSS hiring engineers as full-time job in U.S and Europe.On the other in Japan there are a bit increased but almost are not full-time job.And I used to talk to some attendees at CLS12 that there were few OSS community managers in Japan -that job seemed to be needless in almost Japanese OSS companies because almost Japanese communities are very much techical-oriented,so they don’t need such a job – might better hire engineers for their marketing strategies.but not full-time OSS job engineers feel difficulty to contribute OSS and more lang barriers makes me difficult to do that.
(Note: I had a chance to talk a famous OSS company representative in Japan he talked me OSS manager getting more less-needed OSS community getting more matured.he told me the manager might be harm for their business at some cases .Certainly I haven’t heard at all lately from OSS community manager in the company and more one of the manager is my friend but he already resigned the job)

3.is serious issues especially infra OSS and OSH communities almost members getting older and geeker thus younger keeping away from such a communities – establish another communities.it is well-known A average ages in a OSH community members is 48-50 (Certainly a Linux Users Group in U.S. has almost the same issue).so we need to dare to ‘open’ for youngers and beginners.
Note Lightweight Languages communities or Applications communities succeed to gather younger -perhaps their communities very young can easily gather them.

4.is, I am sure it is especially issue in Japan.I introduced what happened at CLS with my pics taken there.almost of them would love to talk their experiences but almost Japanese are hesitated to talk to audience and more hesitate to lead a community.so most difficult issue at Japanese OSS community is ‘choose Leader and stay as Leader’.democracy is infiltrated in almost countries but some misunderstand what ‘democracy’ is.once the Leader is elected he has privileges to manage his community.but sometimes a member strongly disagree with/dismiss/oppose/ some issues,then Leader talk to his/her ‘Okay do it yourself if you can it is okay’,he/She turn to much mad ‘Why you can’t do/hear my opinion and do yourself I CANT UNDERSTAND LEADER IS CRAZY!’ Leader lost confidence and feel much difficulty to manage his community.An attendees suggested OSS Leaders should ‘take it easy’ to handle his communities.he told ’lightweight management’ was good way to lead it and lead a members up to the project they would do – if the project failed and vanished it might be okay,do another project,it is the element needed to keep the platform for OSS community.
(but other said crash-and-build the project and lightweight management need to the help from ‘butler Company’ I used to join Sun OpenSolaris community,Sun used to work too much for us as a butler (they had over 200-300 employees for that!)- help manage community,sending some stuff for us and more)

5.is lately there are excessive (overacted) gamification in Japanese OSS community using ‘girl’ and ‘moe’ some OSS community using too much with them to gather members.but some girl and moe is not ‘related’ in the OSS skills or some.A community elected a ’moe’ girl as their OSS Leader but she doesn’t have management skill and any OSS skills but in fact she is elected because it prevents from the conflict with each members – there were many between them.but Some girls OSS communities discomfort such a activities,is feeling mad at such a ‘gender abuse’.lately ‘male’ members using such the abuses – makes ‘females’ keeping away from the OSS communities and more divorced from the male communities.’

We haven’t had some conclusions above the issue but we would continue to talk near future.

I have’nt introduced one of the most fascinate activities for Japanese RPi community – Eject command Users group by Ouchi Akira , @akkiesoft though I have known him for a long while 🙂

Eject Command is doing something through pushing and pulling out CD’s tray – ex.it powering on/off air conditioners.for more info please check the link his activities and if you are interested please join his community.



I’m remembering akkiesoft playing around at Open Source Conference and Raspberry Jam – was very cool thus make Eben and us happy.and has become famous RPi communities all over the world.Liz mentioned on official blog and said the he was ‘great’.now he going and work toward ‘the first step’.

Next he should blog in Engish and disuss with Eben 🙂 ,Akkie (☝ ՞ਊ ՞)☝ ウィーン

Hi All,

Since OpenSolaris getting started it was fascinated we would use
‘Opened’ Solaris and concern some developments.I co-worked with
Sun(Oracle) China guys they were great to help and contribute my
project.much appreciated.

I would say I thank you for your kindness and contribution.I,Bo and
Chonan have decided to dismiss our Tokyo OpenSolaris UG and Eee PC
Project and most of members might go ‘illumos UG’.very sad but Oracle
decommission OSOL webiste,ML and MORE.

Jim Grisanzio,who still work for Oracle,helping us our community and
Deirdré Straughan,who now working for Joyent and Albert Lee,who now
working for Nexenta,would help you joining illumos community.Sure,I
will help to re-join Japanese OpenSolaris UG lead by Yasushi Taki

Really really sorry to say the decommission.hope you will have a fun with illumos.

‘OpenSolaris is still going on,Go illumos’

Leader of Tokyo OpenSolaris Users Group
Lead of OpenSolaris for Eee project

According to JavaFX Advent Calendar 2012,I would write JavaFX on PI.

Note you should use ‘Hard-float’ not ‘Soft-float’ as you usually use for Oracle Java.Just download it ,untar and get the sample files.

Well just wondering no recognizing VNC and Wireless Keyboard and mouse.say ‘device error’ while executing.I haven’t tried the sample on github.but other samples on Oracle JavaFX site doesn’t work good the samples always say ‘glGetError 0x500’ – an OpenGL Error.wondering why they say.

here are pics executing.but you should read the known issues.there are too much I can’t help giving up…need to much more time for developing just Oracle teasing us.

According to ‘Java Advent Calendar’ I just blog Getting Started Java on Raspberry PI.

First you should choose Java – Oracle Java or OpenJDK.if you choose Oracle Java you should use ‘Soft-float Debian wheezy’,or wont work on ‘Hard-float’,is a bit older.if you use Rev.B w/512MB after installation to SD,you should replace start.elf as follows.

git git://github.com/raspberrypi/firmware.git
cd firmware;git checkout;git checkout -b 48f8bb0e47
cd boot
cp armXXX_start.elf /Volume/$SD_NAME/start.elf (Mac OS X)
*arm496_start.elf or arm448_start.elf is prefer to use.

and please be careful installing JBOSS,use Oracle Java Embedded Suite for the installation.

if you use OpenJDK,you don’t have to.only download ‘Hard-float Raspbian wheezy’ and get it with apt-get.if you use jetty you might use JamVM,lightweight VM for Embedded.the installation is as follows.

sudo apt-get install openjdk-7-jdk git libtool autoconf automake
git clone git://git.berlios.de/jamvm
cd jamvm
./autogen.sh –with-java-runtime- library=openjdk7
sudo cp src/.libs/libjvm.so /usr/lib/jvm/java-7-openjdk-armhf/jre/lib/arm/jamvm/

hope to make it with Java you should also check my slideshare http://www.slideshare.net/masafumi_ohta/raspberry-pi-on-java-20121110
