OpenSolaris DTrace @ Yokohama Linux UG

I went to the Yokohama Linux User Group meeting held at Rakuten Inc., in Shinagawa Seaside (far away), earlier tonight to see Hisayoshi Kato and Mikiya Okuno talk about DTrace. There were more than 80 guys there from multiple communities including OpenSolaris, Linux, BSD, MySQL, and others. For more on DTrace, including some Japanese presentations, see the OpenSolaris DTrace Day event from last Saturday in Tokyo.

DTrace Day Tokyo: Photos

Here are 13 images from DTrace Day in Tokyo earlier today. This was an event organized by the Japanese OpenSolaris community, which gets together monthly (sometimes multiple times a month). There were 51 guys who came by for the six sessions that ran all afternoon. I think they all went out for a nomikai afterwards, but I couldn’t make it. Had to go swimming instead. Anyway, it was great to see so many new people come out on a beautiful Saturday afternoon. About half the people were first-timers to the OpenSolaris community.

Massive DTrace Day Coming to Tokyo

The Japanese OpenSolaris Community will be hosting a massive DTrace Day on Saturday, March 27th in Yoga. Meeting details are here in Japanese and here in English. Directions with photos are here in Japanese and English. There will be two rooms to hold the six sessions. All talks will be on DTrace and everything will be in Japanese. A nomikai will follow (of course). Developers working on all operating systems platforms are welcome.

DTrace at Yokohama Linux User Group

kato dtrace zfs japanIn my job I meet a lot of interesting engineers. That’s why I like what I do. I don’t really get the technology that deeply, but I do very much find the people fascinating. It’s the people who build communities. It’s the people who create history.

Anyway, one character I know here in Tokyo is Hisayoshi Kato (blog, twitter). He’s a core developer in the Japan OpenSolaris community. He’ll be presenting DTrace at the Yokohama Linux User Group (YLUG) Monday night March 29th (and don’t forget DTrace Day on the 27th at the OpenSolaris User Group). If you know Japanese and you want to know DTrace, you should go to these presentations. Everyone is welcome.

Kato-san presented DTrace at the Tokyo Linux User Group a while back, and he’s done technical talks at many FOSS conferences and user groups meetings throughout Japan. He also knows a bunch about ZFS, too. He’s a co-author of this book on ZFS, which is an original work in Japanese. And finally, if you are are going to the Linux Foundation Collaboration Summit in San Francisco in April, you may bump into Kato-san there as well. Hopefully, he’ll be able to meet up with some OpenSolaris guys in the Bay Area during the Linux conference.

DTrace in FreeBSD 7.1

Nice to see DTrace officially in FreeBSD 7.1. ZDNet news article here. FreeBSD announcement here. DTrace community on OpenSolaris here. Also, I see that the AsiaBSDCon 2009 conference will be held at the Tokyo University of Science in mid March. Cool. I should be around in March, so I`m looking forward to hanging around this conference for a bit.

Well, what did you expect?

All day today while the West Coast of the U.S. has been sleeping, I've been reading articles in the media about Sun's new open storage appliances -- the Sun Storage 7110, 7210, and 7410. The Wall Street Journal, Forbes, and the tech media all had articles on these new systems. But the Forbes piece grabbed me right in the first paragraph: "Give Sun Microsystems credit: The roof may be on fire, but the beleaguered server vendor seems just as focused on putting out innovative products as putting out the flames." Nice bit. But my first reaction was, "well, what did you expect?" Ok, times are tough, but we sure as hell aren't curling up in a little ball and going away, right? I like the focus on innovation and the determination to build something new. I like the buzz in the blogs. That's what you should expect.

Anyway, Bryan has the entire story with links to the whole team, so I'll just point there so you can start with Fishworks engineering. I know this project has been going for some time, and the entire team deserves a massive congratulations. Enjoy the day!

Faster, Cheaper, More Reliable

Sun’s ZFS/Flash initiative: "One of the core developers, Adam Leventhal, has  an interesting article in the July ACM on how this going to work -- the technology is non obvious, but the bottom line is simple: much faster, cheaper, and more reliable storage for big installations." -- Paul Murphy, ZDNet

Contributing to DTrace

I can see I'll never have a career as an interviewer, but that's ok. Blogging is easier. Anyway, Deirdre Straughan was kind enough to record a conversation I had with Chad Mynhier, a contributor to DTrace, at the OpenSolaris Developer Conference last month. Chad also spoke at OSDevCon. Very nice guy. Audio here

DTrace at Tokyo Linux User Group: Photos

Sun`s Shoji Haraguchi and Hisayoshi Kato presented DTrace with a bunch of demos at the Tokyo Linux User Group meeting yesterday. Lars Kotthoff also presented reading Felica cards from Linux/BSD. I took 88 images and dumped 40 or so on the train ride home. The stuff below is what survived. It was a good day (and night) with about 50 people turning up. I had been wanting to get the OpenSolaris guys together with the Linux and BSD guys for a while now since I seem to mix in both crowds these days. We got together at the launch of OpenSolaris 2008.05 and then again tonight, so hopefully we can have more meetings in the future with all three operating system communities.

An Offer You Can't Refuse

DTrace on Linux: "Paul Fox has a nascent port of DTrace to Linux. Paul still has a long way to go (and I'm sure he could use whatever help Linux folks are willing to offer) but it's impossible to believe that Paul isn't on a shorter and more realistic path than SystemTap to achieving safe, powerful, flexible -- and usable! -- dynamic Linux instrumentation. Good luck to you Paul; we continue to be available to help where we can -- and may the Linux community realize the value of your work sooner rather than later!" -- Bryan Cantrill.

That's quite an offer, don't you think? Help from the DTrace guys. Very cool. More on DTrace and Linux here from Stephen O'Grady.

DTrace Conference

Reading Bryan Cantrill's dtrace.conf(08) is a good reminder that community building can be done quite elegantly when the core people are directly involved.

DTrace and OpenSolaris Bug Attack at FOSS.IN

Some shots from yesterday at FOSS.IN. The DTrace BOF and the OpenSolaris Hackathon were most impressive. It was wild to see the everyone banging on OpenSolaris bugs in the hack session -- all new contributions on the way. The energy around the entire conference was massively high all day.

Jarod Jensen Blogs

Thanks to Chris for finally getting Jarod Jensen to blog. This is good news for anyone interested in DTrace. See Jarod's stuff at DTrace Blog: The Texas Ranger. I collect Jarod links here if you are interested in more background. He's one of those must-meet guys, trust me.

OpenSolaris Ports: DTrace, ZFS

It's really nice to see that the DTrace port to FreeBSD is moving right along and also that there are now some ports of ZFS (to DragonFly BSD and to FUSE/Linux) in the works. Activities like these help us connect with developers in other communities -- which I can see we'll be doing a lot of as OpenSolaris grows.

Rubber Meets the Road

I've always loved the expression, "Where the rubber meets the road." It's just a simple way of putting something that cuts through the parsing, the shades of grey, the excuses, the nuances. The bullshit, basically. It works or it doesn't. So it's my favorite quote from this really nice Q&A where Kirk McKusick interviews Jarod Jensen. They dive into the reality and complexity of performance issues in mission-critical business systems. Somewhere buried in the article Jarod says, "What is always best, in my opinion, is to go to where the rubber meets the road. The developers ..." Also some excellent conversation about working in teams, organizational dynamics, and just plain taking responsibility for problems. Jarod shoots straight. He's remarkably precise. And I get the impression he focuses a lot. If you've never met him, don't miss the opportunity if you have the chance. He's pure gold. Here's another recent interview as well.
