Am 5.+6. Februar 2011 findet in Brüssel die "Free and Open Source Software Developers' European Meeting" (FOSDEM) - Konferenz statt. Auch im nächsten Jahr wird es wieder einen "Developer Room" zum Thema MySQL geben. Unter dem Motto "MySQL & Friends" möchten wir ein umfangreiches Programm an Vorträgen rund um den MySQL Server zusammenstellen, mit dem wir Entwickler und MySQL-Administratoren gleichermaßen ansprechen wollen.

Jeder Vortrag wird 20 Minuten dauern (plus 5 Minuten Q&A). Es sind insgesamt 12 Slots zu vergeben. Der Call for Papers ist bereits eröffnet - Vorschläge für Vorträge (in englischer Sprache) können bis Sonntag, 26. Dezember hier eingereicht werden.

Weitere Informationen gibt es auf dem MySQL Forge Wiki und dem englischen Call for Papers.

Ich freue mich auf Eure Themenvorschläge!

It's that time of the year again — the nice folks at FOSDEM have granted us a developer room at their upcoming conference (February 5+6 2011 in Brussels, Belgium)!

As usual there were more applications than they were able to accommodate, so we are very grateful for this opportunity for collaboration. Titled "MySQL and Friends", our room next year will be H.2213 with a capacity of 100 seats. It will be at our disposal on Saturday 5th, from 13:00 till 19:00. Like last year, we would like to set up a schedule of talks related to the MySQL server and the various projects that surround it. Each talk will last 20 minutes, plus 5 minutes of Q&A and a 5 minute break for switching speakers, giving us 12 slots in total to fill with excellent tech talks. Take a look at this year's schedule for some examples! I hope we can assemble an even more exciting and interesting schedule for next year.

Quoting from my last year's call for papers:

We are looking for covering a wide range of topics that attract both MySQL DBAs as well as application developers that work with MySQL as their database of choice. Are you developing a new storage engine or other plugin? Do you want to share your experiences and best practices in administering or deploying MySQL servers? Did you develop a new method to scale a MySQL setup? Let us and the audience know about it! You can submit your talk proposal via this submission form.

The deadline for turning in your proposal is Sunday, 26th of December, 2010, after which there will be a voting and rating period to identify the most interesting and attractive topics.

Please check the FOSDEM 2011 information page on the MySQL Forge Wiki for more details and don't hesitate to contact me directly, if you have any questions or suggestions. I look forward to your proposals!

Auf der amoocon 2010 in Rostock wurde ich von Ralf Spenneberg angesprochen, ob ich nicht Lust hätte, auf seiner OpenSource-Konferenz einen Vortrag zum Thema MySQL zu halten.

Die habe ich – am 23. September um 14:30 werde ich dort etwas zum Thema "MySQL Hochverfügbarkeit" erzählen. Der Vortrag soll einen Überblick darüber geben, mit welchen Mitteln und Methoden man einen MySQL-Server ausfallsicher machen kann und welche Aspekte dabei zu berücksichtigen sind.

Die OpenSource Trends Days erstrecken sich über zwei Tage; am ersten Tag gibt es Tutorien zu den Themen "Check-MK - Das Nagios-Über-Plugin" und "Kolab - Der Exchange-Killer". Am zweiten Tag gibt es neben meinem Vortrag noch Beiträge zu Postfix, Kolab, Fehlertoleranz mit KVM und XEN, OpenVPN und Nagios – ein vielversprechendes Programm von namhaften Experten auf diesen Gebieten.

Für Spenneberg-Bestandskunden ist die Teilnahme kostenlos, die reguläre Teilnahmegebühr ist mit 99 EUR pro Tag durchaus erschwinglich. Ich freue mich darauf!

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.

Greetings from Sankt Augustin, Germany! I've arrived by train today and just returned from the FrOSCon venue, which will start tomorrow. The organizers are still busy with the preparations, but things already seem to be in good shape.

It was a mild and sunny evening today. Hopefully it will be the same tomorrow again, so we can enjoy a relaxed BBQ outside! The social event at FrOSCon is always a nice opportunity to meet and talk with fellow open source enthusiasts, users and developers.

And finally some good news for those of you who can't make it to FrOSCon this year: there will be live video streams from selected lecture rooms! So you will be able to attend the OpenSQL Camp sessions virtually - just head over to http://live.froscon.org/ and select room "HS6". It'll be interesting to see how this will work out.

In just two days the OpenSQL Camp Europe (hosted by the excellent FrOSCon) will kick off!

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.

The most up-to-date version of the schedule is on the OpenSQL Camp Wiki, I expect the remaining changes to be reflected on the FrOSCon schedule during the day as well.

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!

I just wanted to send out a friendly reminder: you still have time until next Monday, 16th of August, 8:00 am (UK) to submit MySQL-related talk proposals for the Conference Series Technology & E-Business Suite 2010 conference which will take place in Birmingham (Nov. 29th - Dec. 1st). The UK Oracle User Group is looking forward to set up a dedicated track with great talks about MySQL! Thank you.

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.

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!
