Lenz Grimmer's blog

I'm happy to announce that my talk "Making MySQL administration a breeze - a look into a MySQL DBA's toolchest" has been accepted for this year's edition of the MySQL Conference & Expo in Santa Clara, which will take place on April 12-15, 2010. The session is currently scheduled for Wednesday 14th, 10:50 in Ballroom E.

My plan is to provide an overview over the most popular utilities and applications that a MySQL DBA should be aware of to make his life easier. The focus will be on Linux/Unix applications available under opensource licenses that ease tasks related to user administration, setting up and administering replication setups, performing backups and security audits.

Of course I will cover the usual suspects (e.g. Maatkit), some of these are actually collections of different utilities by themselves. As it's impossible to go over each individual component in the given time frame, I will try to pick out the most popular/useful parts related to the scopes mentioned above. But I will also cover some lesser known gems that migh be worth taking a look at. What's your the most valued tool in your toolchest? I am still looking for more inspiration.

I look forward to being at the conference again and meeting with colleagues and friends in the MySQL community. Judging from the current schedule, it will be a very interesting mix of talks.

If you're interested in attending, you should consider registering soon! The early registration ends on March 15th. Until then, I encourage you to make use of this "Friend of Speaker" discount code (25% off): mys10fsp

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:

• Robert Nyman: JavaScript - From Birth To Closure (slides, video)
• Glenn Jones: Re-using social media data (slides)
• Brian LeRoux: PhoneGap: Mobile App Developer Zero to Hero (video)
• Brian LeRoux: The State of JavaScript on Mobile Devices
• Walter Belgers: Becoming a lockpicker

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!

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, 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.

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!

 

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:

• http://opensqlcamp.org/Events/2009/Proposed_Sessions
• http://opensqlcamp.org/Events/2009/Reviewing_and_Voting

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!

• Sheeri K. Cabral: A Better mysqltuner (Video)
• Linas Virbalas: Bringing Master/Slave into the 21st Century using Tungsten Database Clustering (Video)
• Holger Klemt: Firebird - a really free database used in free and commercial projects (Video)
• Seppo Jaakola: Galera Replication (Video)
• Kristian Waagan: Getting acquainted with Apache Derby (Video)
• Stephane Combaudon: Minimizing data access with covering indexes
• Lenz Grimmer: MySQL High Availability Solutions (Video)
• Jan Kneschke: MySQL Proxy: a MySQL toolbox (Video)
• Felix Schupp: New kid on the block: The BlackRay Data Engine (Video)
• Vladimir Kolesnikov: PBXT: Technology trends that affect your database (Video)
• Panel Discussion: The OSS Toolshed Shootout (Video)
• Darren Cassar: Securich - MySQL user administration and security made easy!
• Giuseppe Maxia: Sharding for the masses (Video)
• Geert Vanderkelen: An introduction to MySQL Cluster

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!

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!

 

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!

Giuseppe stumbled over this website and recommended it to me as a potential useful service for organizing the registrations of the OpenSQL Camp: Eventbrite is a Python/MySQL-powered web site (judging from their job openings) that provides the following:

Eventbrite is the leading provider of online event management and ticketing services. Eventbrite makes it easy for anyone to hold a successful event of any type and size. Eventbrite is free if your event is free. If you sell tickets to your event, Eventbrite collects a small fee per ticket. So just like you, Eventbrite wants your event to be a big success.

The Eventbrite service includes many features and tools intended to let you perform three basic tasks really well:

1. Publish: Everything you need to create and easily personalize a custom web page for your event.
2. Promote: The tools you need to spread the word about your event and maximize attendance.
3. Sell: The immediate power to sell tickets and collect money online.

I won't use it for the OpenSQL Camp (as we will be able to piggyback on FrOSCon's event infrastructure), but it seems like a service worthwhile checking out, if you're looking for a way to organize your next MySQL meetup (and you're based in the US - currently Eventbrite seems to assume USD as the only available currency). I've added a note about it to the suggestions on the how to run a MySQL User Group page on the MySQL Forge Wiki. And if you do use it, please make sure to add your group to the list of MySQL User Groups! Thanks.

Searching the service for "MySQL" revealed that the MySQL Dublin Meetup actually uses it for organizing their upcoming meeting (June 24, but already sold out)!

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

• An introduction/overview about a certain database project/product or related tool
• A deeply technical and developer-centric session about some project's internals or an API to connect to a database
• Providing "best practices" information for administrators

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).
Baron Schwartz and Colin Charles wrote about the same topic - please keep these recommendations in mind when writing up your proposal! This makes it much easier for us to rate and review your submission.

Suggested projects

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):

• Axion
• Berkeley DB
• CouchDB
• Apache Derby / Sun JavaDB
• Drizzle
• Firebird
• Hadoop
• Infobright
• HSQLDB
• Ingres
• MySQL
• Perst
• memcached
• Pentaho
• PostgreSQL
• SQLite
• Continuent Sequoia/Tungsten Replicator

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 just realized that I haven't blogged for more than a month! Shame on me. But I will blame it on being away on conferences and vacation for quite some time And if you are following me on twitter, you may have noticed what I was going on in my life and that I did't get hit by a bus...

So what was going on since I returned back home from the MySQL Conference? First off, I uploaded und sorted my pictures from the conference and the Drizzle developer day on Flickr. I also uploaded the slides (PDF) from Colin and myself speaking about "MySQL Server Backup, Restoration, and Disaster Recovery Planning" to the MySQL Conference site and they are now available for download from the session page.

On May 4th and 5th I attended the amoocon in Rostock, Germany - a conference primarily about Open Source Telephony and VoIP, where I gave two talks (in German) about MySQL HA Solutions and MySQL Backup and Security Best Practices. There were several other MySQL-related sessions at this conference (e.g. Geert speaking about MySQL Cluster) and I was quite impressed to learn about how widely used it is in the VoIP/Telephony sector. The PDFs of my slides for both talks are available from the conference web site as well as on my slidespace on SlideShare (a very convenient service that I recently started using). There even is an MP3 and video recording of the HA talk, which is also linked from the session page mentioned above.

Right after the amoocon, I attended the next09 conference, which took place in Hamburg, Germany. On the first day I helped manning the Sun booth for some time (Sun Startup Essentials Germany was a sponsor of the event) and listened to some talks, on Wednesday I gave a presentation about "Working for a Virtual Company: How do we do it at MySQL?". A video recording of my talk is available from sevenload. Last time I checked the video was truncated, but I hope they will publish a complete version of it soon. Unfortunately I had a very bad speaking slot - the very first one in the morning (9:00am), after there was a party/social event going on the night before... But luckily there still were ~20-30 people in the audience. This was the first time that I gave this presentation and talked about something less technical, which was actually quite fun! As for the other recent talks, the slides are on SlideShare.

From May 14th to the 16th I was in Verona, Italy to speak about MySQL Backup and Security and bzr - The Bazaar source revision control system at the Italian phpDay. This was quite a nice event with ~150 attendees and Rasmus Lerdorf giving two talks as well. However, many of the sessions were in Italian, so I decided to spend some time walking around the city and taking lots of pictures. I also took a number pictures from the conference, but the light was pretty dim in the room and many shots turned out to be too blurry. Next year they plan to have the phpDay in Rimini - I definitely plan to be there!

Today I attended the Drizzle Developer Day which took place in the auditorium of the Sun Campus in Santa Clara.

Many of the the Drizzle core hackers as well as several other people interested in the development attended this event, hacking away and discussing various issues. Jeremy Zawodny gave a presentation about Craigslist's needs for Drizzle, Jay Pipes gave an overview over Google's protocol buffers library. I took a number of pictures, which you can find in my Flickr photo set.

I joined a group of people that haven't built Drizzle from source by themselves so far, helping them with installing Bazaar and the required libraries. As Drizzle requires several third-party libraries that sometimes are not included in the common linux distributions (or only in outdated versions), we spent some time in getting these build requirements fulfilled.

One of the requirements for building Drizzle is libdrizzle - the client & protocol library. So one first has to download and compile this one, before the actual build of the server can proceed. I noticed that the libdrizzle source distribution contained an RPM spec file already, so I've been working on adding libdrizzle to the openSUSE build service today. The packages for various distributions (Fedora, openSUSE, RHEL, Mandriva) will be available for download shortly. Along the way I also fixed several small issues in the spec file and created a libdrizzle-devel subpackage. The patches are now proposed for merging on Launchpad, I hope Eric will take a look at these shortly.
