Vorab ein Disclaimer: nein, ich bin nicht auf der Suche nach einen neuen Job
Ich habe auf der FrOSCon am letzten Wochenende Lukas Chaplin endlich mal persönlich getroffen, nachdem wir schon seit längerem in Online-Kontakt standen. Er betreibt das Job-Portal Linux Lancers (powered by MySQL), auf dem Stellenanzeigen mit dem Schwerpunkt auf Unix-, Linux- und Open Source-Jobs veröffentlicht werden. Dieses Jahr waren sie auf der FrOSCon als Gold-Sponsor und Aussteller vertreten und hatten wohl immer viel zu tun.
Ich finde diese Idee sehr gut – es zeigt, daß die Arbeit an und mit Open Source Software durchaus keine brotlose Kunst ist und Know-How in vielen Bereichen dringend gesucht wird. Mir ist bisher kein weiteres Portal mit diesem Fokus bekannt. Eine Suche nach "MySQL" liefert viele Hits, quer über die Republik verteilt. Kenntnisse und Erfahrung mit Opensource-Technologien zahlen sich aus! Die Website ist noch in einer frühen Betaphase, aber das machen die Inhalte wieder wett. Laut Lukas ist ein Relaunch des Portals in Arbeit, bei dem sowohl die Suchlogik als auch die Darstellung der Suchergebnisse überarbeitet wird.

With OpenSQL Camp and FrOSCon being over for almost a week now, it's time to come up with a short summary. I traveled home on Monday morning and then took Tuesday off, so I had some catching up to do...
As for the past years, FrOSCon rocked again! According to the closing keynote, they had around 1.500 (unique) visitors and I had a great time there. I really enjoyed meeting all the old and new faces of the various Open Source communities. The lineup of speakers was excellent, Jon "maddog" Hall's keynote about "Free and Open Source Software in the Developing World" was quite insightful and inspiring.
Most of the time I was busy with speaking at and running the OpenSQL Camp session track in room "HS6", but I managed to sneak out and listen to a few other talks as well. Additionally, I gave a presentation about ZFS on Linux, which had a good crowd and some interesting discussions.
This year, all of the sessions in the main lecture halls were streamed live, so people not able to attend could at least get a glimpse on what was going on these two days. Many times it was a really tough decision to make – there were way too many good sessions going in parallel. So being able to see the recording afterwards somewhat relieved that pain. The FrOSCon team has already begun to publish the video files – they are separated by day and lecture room and can be obtained from http://froscon.tv/.
And we were really lucky with the weather, too - the weekend was warm and sunny, a perfect setting for the social event, which is one of the highlights of FrOSCon. Impressive: this year, the attendees consumed one cubic meter (1000 liters) of Beer!
Finally, I'd like to express my special gratitude to all the speakers of OpenSQL Camp – thank you very much for your support and for devoting your time to participate in our subconference! It was appreciated.

We've had a few last-minute changes to the schedule, as some speakers could not make it due to visa or family issues. But we managed to keep all slots filled on both days and I think we've come up with a very nice program! In addition to the two sessions I already had, I've volunteered to take over Giuseppe's talk about Shooting from the Hip. MySQL at the Command Line.
I would like to express my special gratitude to the folks at Percona, who really did their utmost in order to find replacement speakers for their accepted talks.
I look forward to this weekend. And if you're interested to attend: I still have a few vouchers for free admission to the conference left over. Please contact me directly if you'd like to get one – first come, first serve! See you on Saturday!

Ich möchte nur kurz auf einige Konferenzen mit MySQL-Inhalten aufmerksam machen, die in der nächsten Zeit so anstehen:
Am nächsten Wochenende (21. und 22. August) findet in Sankt Augustin bei Bonn die Free and Open Source Software Conference (FrOSCon) statt. Auch in diesem Jahr wird es wieder einen von mir organisierten Track namens "OpenSQL Camp" geben. Es wird insgesamt 12 Vorträge rund um das Thema MySQL und andere Open-Source Datenbanken geben. Darüberhinaus haben die Veranstalter der FrOSCon einen dedizierten Track zum Thema "NoSQL Datenbanken" zusammengestellt. Es wird also reichlich Information zum Thema Datenbanken auf der FrOSCon geben!
Ich habe übrigens 10 Freikarten für die FrOSCon zu vergeben, die Teil unseres Sponsoring-Pakets sind (MySQL/Oracle ist Silber-Sponsor). Wer Interesse hat, sollte sich schnell bei mir per E-Mail melden – first come, first serve!
Das nächste OpenSQL Camp findet dann wieder in den USA statt, und zwar vom 15. bis 17. Oktober in Boston.
Davor gibt es noch einen Pflichttermin in den USA – die im September in San Francisco stattfindende Oracle OpenWorld, die dieses Mal gleich mehrere Konferenzen unter einem Dach anbietet: neben der "klassischen OpenWorld" wird es die Java One und Oracle Develop Entwicklerkonferenzen sowie den MySQL Sunday geben. Besonders letzterer verspricht interessant zu werden, es haben viele namhafte Speaker aus der MySQL-Community zugesagt.
Herbst und Winter ist traditionell Hochsaison was Konferenzen angeht, und auch dieses Jahr wird wieder einiges geboten. Seit der Übernahme von MySQL durch Oracle zeigen sich besonders die diversen Oracle-Anwendergruppen sehr stark daran interessiert, das Thema MySQL aufzugreifen. Nach der ODTUG Kaleidoscope, die im Juni/Juli in den USA stattfand, stehen nun die DOAG Konferenz in Nürnberg (16.-18. November) und die UKOUG Conference Series Technology & E-Business Suite 2010 in Birmingham (29. November - 1. Dezember) an, die ebenfalls dedizierte Vortragsreihen zum Thema MySQL anbieten werden. Achtung: für die Konferenz in England können noch bis kommenden Montag Vortragsvorschläge eingereicht werden! Wir freuen uns über jeden Beitrag.

I tend to switch between Linux and OpenSolaris as my desktop operating system from time to time. To be more flexible in this setup, I store most of my work-related data (e.g. source trees, VirtualBox images) on an external 320GB USB disk drive, using the ZFS file system. While OpenSolaris supports ZFS natively, I can access the file system on Linux using zfs-fuse and I could even mount these file systems on a FreeBSD system, if needed. There aren't that many file systems that allow an easy exchange of data between (Open)Solaris and Linux – the other ones that I am aware of are FAT and UFS, which both don't give me the confidence and flexibility I need.
A while ago, I purchased a second external drive of the same size and now use both of them in a mirrored configuration. This gives me several benefits:
From my experience, ZFS is a very solid and reliable solution, providing impressive functionality with a very user-friendly UI (you only need use two commands, zfs and zpool).

If you wonder why there hasn't been an update from me for quite a while — I just returned from two months of paternal leave, in which I actually managed to stay away from the PC most of the time. In the meanwhile, I've officially become an Oracle employee and there is a lot of administrative things to take care of... But it feels good to be back!
During my absence, Giuseppe and Felix kicked off the Call for Papers for this year's European OpenSQL Camp, which will again take place in parallel to FrOSCon in St. Augustin (Germany) on August 21st/22nd. We've received a number of great submissions, now we would like to ask our community about your favourites!
Basically it's "one vote per person per session" and you can cast your votes in two ways, either by twittering @opensqlcamp or via the opensqlcamp mailing list. The procedure is outlined in more detail on this wiki page.
As we need to finalize the schedule and inform the speakers, the voting period will close this coming Sunday, 18th of July. So don't hesitate, cast your votes now! Based on your feedback we will compile the session schedule for this year's camp. Thanks for your help!

First off, I would like to thank all of the participants and supporters, particularly my colleagues Regina Steyer and Iris Musiol for the perfect logistics and co-sponsoring as well as Uli Graef, Thorsten Frueauf, Matthias Schmidt, Alexander Rubin and Joerg Moellenkamp for manning the Sun booth and the help on site.
Another big Thank You goes out to my team mates Giuseppe and Colin as well as to Sheeri K. Cabral, who were a big help in keeping the OpenSQL Camp on track and by supporting the event by giving talks. In addition to that, Sheeri recorded most of the OpenSQL Camp sessions on video and published them in record time!
So here's a quick summary of both events from my side, starting with the main conference.
Sun was a Gold sponsor of the event and we had a booth right at the main entrance area; it could hardly be missed. It consisted of two large and two small desks as well as a divider behind them. For demos, we had a (slightly noisy) Sun Fire X2200 M2 Server and four SunRay 2 Thin Clients (which by themselves triggered a lot of questions and curiosity by many visitors). The booth was flanked by rollup-banners on both sides as well as various posters attached to the divider. Here's a picture of our booth before the event opened:
We also had a number of talks in the main conference track (both German and English):
The comments and ratings of these sessions were generally very positive. Our booth was well attended, especially during the session breaks. In total, there were over 1.400 visitors at the conference over the two days.
I personally did not attend many sessions in the main conference tracks, as I was too occupied with the OpenSQL Camp and the booth organization. However, I managed to listen to Uli Graef's talk, which was a very technical and interesting session about ZFS features and internals. Being a big fan of ZFS myself, this was a very worthwhile session to be at and my impression was that it encouraged others to take a closer look at this truly amazing file system.
The second talk I attended was Sunday's keynote by Dries Buytaert from the Drupal project about "The Secrets of Building and Participating in Open Source
As for previous FrOSCons (is that the proper plural?), there was a social event scheduled for Saturday evening, providing barbecue (Steaks and Sausages as well as vegetarian dishes) and drinks. This event usually takes place outside and is always an excellent opportunity for networking and talking with key people from other OSS communities and projects. And there was plenty of time for talking - the queues for the grilled food were long...
Here is a list of other blogs and articles about FrOSCon that are worth a read (in no particular order and both German and English):
In addition to the main conference tracks, FrOSCon also provided a number of so-called "Developer Rooms" to OSS projects, so that they could organize sub-conferences or hackfests of their own. We applied for a room to set up a conference dubbed "OpenSQL Camp", related to the topic of Open Source databases, which was approved.
We then sent out a call for papers and invited people from the many OSS database communities to join us and talk about their projects. Every session proposal was published on the OpenSQL Camp web site and people were able to vote on the sessions they were most interested in via email or twitter:
The organization and scheduling of the talks and speakers was done via the FrOSCon conference system (Pentabarf), which made it very easy to perform this task and also made sure that the OpenSQL Camp sessions were included in the main conference program. Below is a full list of sessions at our subconference (see the FrOSCon Program page for abstracts, speaker info, links and slides). We had two cancellations by speakers on short notice, but were able to cover the gaps with ad-hoc presentations. I'd like to send a special thanks to Geert Vanderkelen, who gave a great presentation about MySQL Cluster despite the very short notice and some technical difficulties at the beginning!
Most talks attracted between 20-50 attendees and we had a great mix of topics from several different database projects (with a slight majority of MySQL-related talks). The Panel Discussion (moderated by me), called the "OSS Toolshed Shootout" went quite well and the speakers had a good time answering questions on various topics about their projects. Thanks again to all OpenSQL Camp speakers for making this event a success!
All in all I think that both FrOSCon and OpenSQL Camp were well worth supporting and attending - we were able to provide insight and trigger some interesting discussions among the OSS enthusiasts and developers in the audience. It was also a good opportunity in get in touch with many people of other OSS communities, fostering the MySQL (and other Sun OSS projects) ecosystem.
I personally look forward to next year's FrOSCon - a Big Thanks to the organizers for another great event!

I'm happy to announce that the schedule for OpenSQL Camp 2009 (European Edition) has been published on the FrOSCon timetable now. We have a great selection of topics and speakers, so don't miss it! OpenSQL Camp is a subconference of FrOSCon, the Free and Open Source Conference, which will take place on August 22nd and 23rd in St. Augustin, Germany.
The admission fee for the entire conference (both days, incl. OpenSQL Camp) is 5 EUR, you can pre-register here until August 10th (and if you do so today, you will still get a free T-Shirt as well!). Of course, you can also just show up at the entrance and pay the entrance fee on site. The OpenSQL Camp will be located in Room C120 - see the instructions on the FrOSCon web page on how to get there and where to find accommodation.
In case you can't make it to Germany for the European Edition, Eric Day and Selena Deckelmann have started to organize another OpenSQL Camp in Portland, Oregon which will take place on November 14th and 15th. More details can be found on the OpenSQL Camp Wiki. Space is limited to 120 attendees, so sign up today and reserve your spot!

The Call for Papers for the OpenSQL Camp 2009 (European Edition) has ended yesterday — we received 27 excellent session proposals from various Open Source Database projects. I would like to say a big "Thank You" to everyone who submitted a talk! In the beginning I was a bit concerned that the conference would become too MySQL-centric, but this fortunately changed in the last few days.
Sadly we now have more than double the amount of sessions than we can actually host, which means that we will have to review and vote on the sessions to distill the final program. We've formed a small committee that will perform this task (currently consisting of Sheeri, Giuseppe and myself) and is in charge of finalizing the schedule. But you can help us with this! We are seeking your input on which sessions you would like to attend until Sunday, July 26th (12:00pm PST).
The system basically asks for "one vote per person per session", giving you a chance to influence the program yourself: you can cast one vote for each session by either stating you would be interested in attending it (+1) or not interested (-1). Additionally, you can add a comment for each vote to provide a reasoning for your choice. Ideally, you should of course plan to actually attend our event, but you are welcome to tell us what you would have been interested in, in case you can't make it to the Camp. See the OpenSQL Camp wiki page for more details and instructions. You can submit your votes via Twitter or the OpenSQL Camp mailing list.
We look forward to your input!

I've now posted all the current talk submissions to the OpenSQL Camp Wiki. A big Thank You to everyone who contributed so far and helped us to bang the drum for this event! If you haven't heard about OpenSQL Camp yet, it's a subconference of the Free and Open Source Conference (FrOSCon) in St. Augustin, Germany, which takes place on August 22+23. The topic of OpenSQL Camp is "Open Source databases and related technologies" and we're looking for interesting presentations in this field.
As we have 12 session slots to fill, we still have room for at least 6 more submissions! It's also a tad bit MySQL-centric at the moment, that should definitely change! We would love to get some more diversity to cover a broader range of Open Source Database technology.
So please submit your talk proposals and help spreading the word — the Call for Papers is still open until July, 19th! Post a message to relevant discussion forums and mailing lists. Know an expert in this field? Approach him directly! OpenSQL Camp Speakers will receive free entry to FrOSCon, which is worth visiting in any case!

The OpenSQL Camp 2009 web site is now ready for business, I've updated various pages and added some more information about the call for papers. I've also set up a Twitter account (no way without one nowadays, right?), which might also play an important role in the voting/rating of talks later on (Giuseppe came up with an interesting proposal for that).
So we're now seeking your input! Let me quote from the web pages directly:
OpenSQL Camp is a free conference of, by, and for the open-source database community of users and developers. The first OpenSQLCamp 2008 took place in Charlottesville, Virginia, USA, November 14, 15, and 16 2008.
The OpenSQLCamp 2009, European Edition will take part in parallel to the Free and Open Source Conference 2009 (FrOSCon) on Saturday 22nd and Sunday 23rd August in St. Augustin, Germany. St. Augustin is located close to Bonn and Cologne.
Attendees of this conference are mostly open source developers and end users/open source enthusiasts. The FrOSCon organizers agreed to provide us with a "Developer Room" for both days, which allows us to organize our own subconference about Open Source Databases and related technologies. The goal of this event is to spread the word about the vibrant communities and large ecosystems around Open Source Databases and to educate the attendees about what alternatives exist to commercial databases. It is a place where people come to learn, to participate and to contribute. In other words, it's a great conference, and if you attend, it will be better.
We are seeking talks related to Open Source Databases of all kind, not just relational databases! Submission about tools and technologies related to OSS databases (e.g. connectors/APIs) are also welcome.
Submitting your proposals
We will use FrOSCon's Pentabarf conference coordination system to collect talk submissions and perform the organizing and scheduling of the talks. Please create an account there, if you don't have one already. Once you have activated your account via the email address you provided, please log into the system and create a new event. Make sure to select track OpenSQLCamp for your submission!
The deadline for submitting your proposal is Sunday, July 19th, 2009!
We will try to synchronize our schedule and speaking slots with the main conference program, to allow easy switching between sessions in the Developer Rooms and the main conference. So your talk should be put into the "Lecture" format and will last one hour (incl. Q&A).
We will try to perform the review and voting about the sessions in public, so the community and potential audience will have a say about which sessions they want to listen to. The details of how this will be done are still under discussion.
A number of database-related talks have already been submitted to the general FrOSCon program. The FrOSCon organizers will evaluate if some of these talks would be more suitable for the OpenSQLCamp track, but stated that they would be interested to keep some of the submitted sessions as part of the main conference program.
Some ideas and suggestions for submissions
Any submission is welcome, as long as it has technical content and it's not a vendor pitch for a commercial program! Open Source is a prerequisite. The conference languages are German and English, so your talk could be of either language.
You should also read Giuseppe's advice on how to get your proposal accepted (it was aimed for the MySQL Conference, but the overall message still applies).
Some database projects and related technologies that we would like to be present at OpenSQLCamp include the following (in alphabetical order, without claim to completeness):
We plan to approach and invite these communities directly to participate and contribute.

Today I received a confirmation that I will be giving a talk about "Working for a virtual company" in the main conference track of the Free and Open Source Conference (FrOSCon) in St. Augustin, Germany (August 22nd+23rd). Yay! I've been giving talks at every FrOSCon since its inception in 2006, so I am happy that I will be able to continue this tradition. FrOSCon is really a gem among the various Linux and Open Source Conferences in Germany — it takes place at a nice venue, the weather is usually warm and sunny and the conference organization is just great. And they of course always have a good lineup of speakers and OSS projects! As for the last years we (Sun/MySQL) will support the event by sponsoring and we will likely have a booth there as well. My colleague Joerg Moellenkamp also received his confirmation, it's quite likely that he'll be speaking about Solaris/OpenSolaris, as that's his home turf
In addition to that, the organizers agreed on providing us with a "Developer Room" for both days, which we would like to use to set up a subconference about Open Source Databases (there will also be a dedicated Java Subconference this year). Dubbed the "OpenSQLCamp 2009, European Edition", we plan to organize two days of talks and presentations to spread the word about the vibrant communities and large ecosystems around Open Source Databases, and to educate the attendees about what alternatives exist to commercial databases. So this will by no means be limited to MySQL only! The more variety, the better. I've set up a page on the OpenSQLCamp.org Wiki with some more details. More information will follow in the coming days. If you're interested to contribute, submit a talk or to know more, please also join the opensqlcamp discussion group! I'd like to thank Sheeri Cabral and Baron Schwartz for giving me a hand with the infrastructure - your help is appreciated!

I'm back home from DrupalCon 2008 now - it has been a great event! I met a lot of nice people from the Drupal Community and learned a lot about this CMS. I've been very busy in uploading the remaining pictures from the event to my gallery - so here's for your viewing pleasure:
I also gave two talks and held a BoF there - the slides have now been attached to the session nodes, one of them (the HA session) even includes a video recording:
Monday, June 23. 2008
While we're on the topic of Bazaar - this week I got informed by the organizers of the FrOSCon 2008 conference that they accepted two of my talk proposals: one session will be an introduction to this source code management system (what a coincidence), the other one will be an introduction to OpenSolaris for Linux users, explaining some of the underlying technologies and how they differ from what a seasoned Linux user may be accustomed to.
And no, I have not given up on using Linux - quite the contrary! I have been very impressed by the latest OpenSUSE 11.0 release and already run it for since quite some time on several of my work systems. In fact, I already convinced several colleagues of mine to give it a try as well! I am amazed by the speed and "out of the box experience" of this version and I actually plan to install it on my Genesi Pegasos PowerPC machine as well, replacing Debian on there. But as a Sun employee, I of course have to familiarize myself with the other products and projects that we're involved in. And on the Server side, Solaris does have a few interesting features that Linux currently lacks. But I digress.
I look forward to speaking at FrOSCon again - it has been a great conference in the past two years. Very well organized, nice venue, a relaxed atmosphere and excellent technical sessions and speakers.
Other MySQLers submitted talks as well - for example, Giuseppe will give a presentation titled "MySQL Community How To", Susanne will give a PostgreSQL tutorial and others will participate in the separate PHP subconference. Don't miss it - this year's FrOSCon will take place on August 23rd&24th in St. Augustin, Germany (close to Bonn). For the first time, we will also try to set up a MySQL project table. So if you are there, make sure to stop by and have a chat with us!
