MySQL-Vortrag auf den OpenSource Trends Days

nospam@example.com (Lenz Grimmer) — Fri, 27 Aug 2010 16:03:30 +0200

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!

OpenSQL Camp Europe and FrOSCon: A summary

nospam@example.com (Lenz Grimmer) — Thu, 26 Aug 2010 13:17:27 +0200

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.

OpenSQL Camp Europe: Some last-minute changes to the schedule

nospam@example.com (Lenz Grimmer) — Thu, 19 Aug 2010 09:43:24 +0200

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!

Reminder - UKOUG Conference CfP closes next Monday!

nospam@example.com (Lenz Grimmer) — Fri, 13 Aug 2010 16:29:34 +0200

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.

Flexible storage handling using ZFS on Linux and OpenSolaris

nospam@example.com (Lenz Grimmer) — Wed, 11 Aug 2010 14:29:42 +0200

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:

Redundancy: external disk drives have a higher risk of getting physically damaged, so having a mirrored copy of my data ensures that I won't lose anything important if one of the drives dies.
Increased performance: ZFS is capable of distributing reads across both devices, thus I get twice the speed of a single USB 2.0 port, if I connect the drives to ports attached to separate USB host controllers.
Automatic resyncing: When I'm on the road, I only take one half of the mirror with me. In case this drive gets lost/stolen, I still have a second copy of the data at home. ZFS complains about the pool being in degraded state, but continues to work normally. When I return home, I simply attach the second drive again and ZFS automatically resyncs (resilvers) anything that has been modified in the meanwhile.
I can use snapshots for backup purposes. I have a small Intel Atom based PC (running OpenSolaris) that acts as my central file server (using two 1TB disks in a ZFS mirror) and CUPS print server. If I want to create a backup of my external USB disks, I create ZFS snapshots of the file systems in question and transfer these to the home server using "zfs send/receive". This works both locally by connecting the drives to the server box directly or via SSH over the network. I wrote a small shell script to automate this process. The transfer is done in an incremental fashion – only the differences between the current and the last snapshot are being propagated. To save disk space on the external drives, I usually discard all older snapshots except for the last one or two. On the file server, I maintain snapshots for a longer time period. The snapshots are named by using a simple date/time timestamp (filesystem@YYYY-MM-DD-HH:MM), this makes it easy to go back to a particular snapshot in case I'm looking for something I may have removed by accident, but I still recall when it was last used.

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 want to learn more about ZFS and how to use it in practice, consider attending my upcoming talk (in German) about this subject at FrOSCon 2010 in Sankt Augustin, Germany!

Upcoming speaking engagements: Grazer Linuxtage and amoocon

nospam@example.com (Lenz Grimmer) — Tue, 30 Mar 2010 16:39:55 +0200

As I already wrote, I will be speaking at the MySQL Conference & Expo in Santa Clara in two weeks and I am excited to be there again. This year's conference is going to be interesting for a number of reasons, but most importantly I think that the schedule looks great! This is going to be a "drinking from the firehose of MySQL knowledge" event. Afterwards, I'll be on parental leave in May and June, so I likely will miss a lot of great conferences – these months are usually quite packed, as our Open Source Events Calendar can confirm. I just received a notice that my talk submission to OSCON has been rejected, which currently leaves me with two more speaking engagements in the upcoming weeks:

On April 24th, I'll be at the Grazer Linuxtage in Graz, Austria. The schedule has not been published yet, but I've been asked to give a keynote on the subject of working in a virtual company and a more technical session about MySQL HA solutions. Linuxtage is said to be the second largest Opensource event in Austria – they had 28 different sessions and around 450 visitors last year. I haven't been to an event in Austria for a while, so I look forward to being there!

Even though I'm technically on leave at that time, I will attend the amoocon in Rostock, Germany in June (4-6). While last year's focus at this event was on opensource telephony (Asterisk, VoIP et al), they decided to broaden the scope for this year's event: "It is a boutique conference where we create an environment to give every attendee a fair chance to actually speak to each speaker. So you can tank knowledge and new ideas without the bullshit-bingo." I really enjoyed my stay there last year and look forward to talking about "A look into a MySQL DBA's toolchest" (for those who won't make it to my talk about this at the MySQL conference) and "Why you should be using a DVCS". I noticed that Monty Widenius will be there as well, speaking about "MariaDB release 5.1 - What is it and what to expect from it." and "MySQL & MariaDB history". The organizers are also looking for a speaker from the PostgreSQL camp, so this is going to be an interesting event for me. In addition to that, Rostock is a pretty nice city and the baltic sea is nearby. The organizers have limited the number of attendees to 100 people and the ticket price is slowly increasing every second day – so make your reservations now!

Back from SAPO Codebits in Lisbon - a summary

nospam@example.com (Lenz Grimmer) — Mon, 07 Dec 2009 15:39:23 +0100

Last week, my colleagues Giuseppe, Kai and myself attended the SAPO Codebits event in Lisbon, Portugal. Codebits is an annual, invite-only hacking event, which went on for three days. The venue they chose this year was the "Cordoaria", a former rope factory located in the Belém district, close to the 25 de Abril Bridge (which is an impressive sight!). I have been told that the Cordoaria is the longest building in Portugal and I have no doubts about that! The building is so long that the crew used bicycles to get from one end to the other. I've taken a number of pictures from the event as well as from Lisbon itself, you can find them in this flickr set.

The organizers described this year's event as follows:

3 days. 24 hours a day. 600 attendees. Talks. Workshops. Lots of food and beverages. 24 hour programming/hacking competition. Quizz Show. Rock Band Contest. Lots of gaming consoles. More food. More beverages. More coding. Sleeping areas. More fun. An unforgettable experience.

I wholeheartedly agree, we had a great time! The conference started with sessions and presentations on a wide range of topics on the first two days. Afterwards, a 24-hour programming contest was held. I was invited to give two talks, one being my all-time favourite about "MySQL High Availability solutions" (slides, video), the other one was titled "Why you should be using a distributed version control system (DVCS) for your project" (video, slides). Both went quite well and the feedback I received was pretty positive. Giuseppe talked about "MySQL Schema Migration" (slides, video) and gave an "Introduction to Gearman" (video). Kai's talk was titled "Think before you develop" (video) and gave a nice roundup of tips and best practices for setting up and developing new web projects.

The Codebits session schedule was filled with amazing and interesting talks in four parallel tracks. Sometimes it was hard to choose – some other talks I attended and enjoyed:

Walter gave a lockpicking workshop after his presentation, which I attended as well. I was quite impressed (and a bit shocked) to find out how easy many locks can be opened this way! Later that evening there even was a live band named "Pornophonique" playing (one guy with a guitar, the other one using an Nintendo Game Boy for making music), but I missed that show as I was too busy opening more locks... Fortunately the concert and most of the sessions were recorded on video (in excellent quality) and are already available from the SAPO video pages. Kudos for this speedy service!

But this just matches my overall conclusion of this event: very well organized, great speakers and venue. Thanks to the organizers for having us, we really enjoyed our stay!

My upcoming event schedule for this year

nospam@example.com (Lenz Grimmer) — Mon, 26 Oct 2009 13:47:02 +0100

This time of the year is usually a very busy one, as there are plenty of events and conferences to attend. Just take a look at our calendar of OSS events on the MySQL Forge to see what I mean! Here's a quick summary of the ones that I will attend and speak at until the end of this year:

On November 14-15, I'll attend the openSQL Camp in Portland (OR), USA. I missed the first one that took place in Charlottesville (VA) in 2008, but had a lot of fun organizing the European Edition earlier this year. The upcoming one will be more like an unconference again - the list of proposed sessions looks very interesting and the attendee list reads like a "who is who" list of the OSS database community.

On December 3-5, I'll be joining Giuseppe at SAPO Codebits in Lisbon, Portugal, which is going to be a very cool event: "3 days. 24 hours a day. 600 attendees. Talks. Workshops. Lots of food and beverages. 24 hour programming/hacking competition. Quizz Show. Rock Band Contest. Lots of gaming consoles. More food. More beverages. More coding. Sleeping areas. More fun. An unforgettable experience". I will be talking about my favorite topic of MySQL High Availability (I'm currently working on revising my slides based on several excellent discussions about MySQL HA that happened on Planet MySQL in the past weeks) and about the benefits (both social and technical) of using a distributed revision control system (DVCS) like bazaar, git or mercurial for your open source project.

Shortly after Codebits, I will attend SLAC 09, the "Secure Linux Administration Conference" in Berlin, Germany (December 10-11), where I will give two MySQL-related talks (in German) - my usual suspects, but in revised and extended form: MySQL High Availability solutions and MySQL Backup & Security best practices.

FOSDEM Call For Participation opened - submit your talks now!

nospam@example.com (Lenz Grimmer) — Mon, 19 Oct 2009 23:42:04 +0200

FOSDEM, the Free and Opensource Conference, will again take place in Brussels, Belgium on Saturday and Sunday (6th and 7th February, 2010). Now happening for the 10th time (congratulations!), it is one of the largest Open Source conferences in Europe, with a strong focus on developers. Sun/MySQL have been regular sponsors of and contributors to the event in the past and it is alway a great experience to be there. It's very rare to meet so many well-known and bright people from such a wide range of OSS projects.

They have now opened their Call for Participation - the organizers are seeking input on talks for the main conference tracks (deadline: 2009-11-22) , lightning talks (deadline 2009-12-28) and project stands (deadline: 2009-11-22).

As for the last conference, we plan to apply for a MySQL developer room (and maybe a project stand, anybody interested to join? Please contact me!). However, the web site currently states that they are "slightly reworking the concept of developer rooms", so it remains to be seen what this will turn into. In any case, we will set up our own call for papers, once the developer room allocations have been finalized (and we were lucky). I was initially thinking about running another OpenSQL Camp, but it's probably too short after the upcoming one in Portland...

If you have an interesting talk about a MySQL-related subject, consider submitting your proposal now! We will gladly review and comment on your proposal in advance, if you would like to get our input or need suggestions about topics! Thanks.

Upcoming events: PHP Unconference and openSUSE Conference

nospam@example.com (Lenz Grimmer) — Mon, 07 Sep 2009 21:48:32 +0200

The summer break seems to be over and the event season is heating up again! There is a number of conferences and events coming up in the next months — here is a quick summary of the events that I plan to attend.

This Friday I will attend an event here in Hamburg: the "Silpion Sommerfest", organized by Silpion (a local IT solutions provider which is a partner of Sun Microsystems as well). I will be there to network and talk about MySQL.

This coming weekend (2009-09-12/2009-09-13), there will be the PHP Unconference here in Hamburg, Germany . It will consist of two days of Barcamp-style sessions about PHP. Sun/MySQL are sponsors of the event and I expect several of my team mates to be there as well. With more than 180 participants, the event is already sold out.

The following week I will be attending the openSUSE Conference in Nuremberg, Germany on 2009-09-17/2009-09-20. I will give the opening keynote on Thursday morning. Titled "Working in a Virtual Community", I will talk about the pros and cons of working in a virtual organization, giving an overview about some of the technical and social aspects that play a role in working with virtual communities.

On December 10th and 11th I will be attending the 4. Secure Linux Administration Conference 2009 (SLAC) in Berlin, Germany. I've been invited to talk about MySQL and will give two sessions about MySQL Backup & Security as well as MySQL High Availability Solutions. The Call for Papers for this event is still open, so if you have a technical, "best practice" talk that might be relevant for system administrators, consider submitting your proposal!

FrOSCon/OpenSQL Camp summary

nospam@example.com (Lenz Grimmer) — Fri, 04 Sep 2009 22:56:00 +0200

It's almost two weeks now since FrOSCon and the OpenSQL Camp subconference have taken place in Sankt Augustin, Germany — about time for a summary and update from my side!

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 demoed Open Solaris, Open HA Cluster, NetBeans/Java and MySQL. We also had a lot of brochures about various products, OpenSolaris 2009.06 Live-CDs incl. booklets as well as some MySQL-T-Shirts to hand out. We distributed over 300 CDs and received a lot of positive feedback about the distribution.

We also had a number of talks in the main conference track (both German and English):

Lenz Grimmer: Working for a Virtual Company - How we do it at MySQL (OGG Video)
Giuseppe Maxia: MySQL Sandbox 3 - Making your life with databases easier than ever (OGG Video)
Ulrich Graef: ZFS - Neue Funktionen und Technologien
Thorsten Früauf: Hochverfügbarkeit mit minimalem Cluster - Open HA Cluster on OpenSolaris (OGG Video)
Jörg Möllenkamp: Insights to Opensolaris (OGG Video)

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
Communities". Dries is a great speaker with visually stunning slides. He is funny, too — if you have a moment, you should watch the video recording of his keynote. An uncut "pre-release" version of his talk is already available as an OGG Video file.

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):

OpenSQL Camp, European Edition

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.

Here is a Flickr slide show of my own pictures - more photos can be found in the FrOSCon Gallery and the links page on the Wiki.

I personally look forward to next year's FrOSCon - a Big Thanks to the organizers for another great event!

Seeking talks for a MySQL Day at this year's International PHP Conference (Nov 15-18)

nospam@example.com (Lenz Grimmer) — Thu, 03 Sep 2009 09:49:33 +0200

IPC 2009, the International PHP Conference will take place on November 15th-18th in Karlsruhe, Germany. While the deadline for the call for papers for the main conference program has already passed, there is still an opportunity to submit MySQL-related content: the organizers plan to have a special MySQL Day, which will take place on Tuesday, 17th of November.

Quoting for the Call for Papers web page:

We are looking for speakers joining the Architecture Day or the MySQL Day. "Architecture", in terms of project organization, business organization, tools & approaches etc. is becoming a key qualification to developers and teams. And MySQL still is one of the most common open source databases used in many of todays leading web applications. The International PHP Conference will provide attendees with professional and up to date information on both MySQL and Architecture in the world of PHP.

We are looking forward to you numerous suggestions and proposals, as usual via http://phpconference.com/input.

We would like to encourage you to support and contribute to this event by submitting interesting talks related to MySQL and PHP! If you have any questions or comments about this MySQL Day, feel free to get in touch with Robert Lippert or Björn Schotte directly. Thank you!

OpenSQL Camp 2009: Session schedule published - pre-register now!

nospam@example.com (Lenz Grimmer) — Thu, 06 Aug 2009 14:03:05 +0200

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.
