GUUG Frühjahrsfachgespräch 2014: CfP ends on May 31st!
Employee +0 Vote Up -0Vote Down

The German Unix User Group (GUUG) will hold their annual conference "Frühjahrsfachgespräch" on September 23-26 this year (I know, not really "Frühjahr" anymore, but this is how it is).

The Call for Presentations is still open until May 31st. Talks can be proposed in German and English, and there are slots for longer tutorials as well.

The range of possible topics is broad, so if you think you have anything interesting to share with a very passionate and technical audience of sysadmins and developers, here are some suggestions:

  • Operating Systems/Applications: architectures, privilege concepts, new developments, administration, mobile systems
  • Relevant new OS Kernel

Open Source Enigma Project

The wild and crazy guys over at S&T Geotronics, James Sanderson and Marc Tessier, have decided to go full tilt with a Kickstarter version of their DIY Open Enigma Project.  For those who missed the fanfare last year, they were featured on Instructables showing how to build an Arduino-based encryption machine that works exactly like a WWII era Enigma.  You know, the thing that

Contributor agreements, a reminder and an update
Employee_Team +3 Vote Up -0Vote Down

One of the many things that hasn't changed with GlassFish since the acquisition is how we welcome contributions from the community (in fact we've seen an increased number of those recently).

The Oracle Contributor Agreement, or OCA (born as the SCA) is a required document before we can accept such contributions and a fairly common practice in open source projects. One important thing that has changed for the OCA is the email address to use for signed contributor agreements. Check this

What have I been up to lately?
Employee +0 Vote Up -0Vote Down

Despite my best intentions, I haven't posted on this blog for a while, which is a shame! I've become busy writing on so many other places since I moved into my new role in the Oracle Linux product management team in April. I've learned a lot and I am feeling quite at home here! The team is excellent and very nice to work with — I am slowly getting the "Big Picture".

But even though I've been neglecting this blog, there are a lot of things that are publicly visible and document some of my activites:

Oracle at fisl12 (Porto Alegre, Brazil, 2011-06-29/2011-07-02)
Employee +1 Vote Up -0Vote Down

fisl12 is likely the largest free and open source software event in Latin America. This year, it takes place in Porto Alegre, Brazil, from June 29th to July 2nd. Oracle is a gold sponsor of the event and I will attend it as a speaker. I feel honoured and excited to be there – for me it will be the first visit to the South American continent.

They already have over 3000 registered attendees, so this definitely is going to be a great conference. There is quite a number of well-known names on the speaker roster and I look forward to meeting a lot of familar faces there.

Back in Linux land
Employee +2 Vote Up -0Vote Down

It's been a while since my last post on this blog; I definitely need to get back into the habit! One of the reasons for my radio silence was that I switched roles here at Oracle. After having been with the MySQL team for 9 years, I felt it was time for a change. Fortunately I did not have to look far – I'm now a member of the Oracle Linux product management team and I am having a lot of fun there.

However, I realized that while I was an active Linux user on the desktop, quite a lot has happened on the enterprise and data center side of things. Linux has really come a long way and I am glad to be back in this field, drinking from the firehose and learning a lot about recent developments and technologies. For me, this is kind of going "back to my roots", as I have been deeply involved with Linux at SuSE before I joined MySQL in

Oracle at LinuxTag 2011 in Berlin, Germany
Employee +1 Vote Up -0Vote Down

Linuxtag is likely one of the oldest and largest Linux/OSS events in Germany. I remember having been there to represent SuSE Linux while it still took place at the University of Kaiserslautern, using tables and chairs from the lecture rooms as exhibition stands (this must have been around 1998 or 1999). This year it will take place in Berlin again, and the session schedule looks very promising. I'll be there from Wednesday till Friday and I feel that I will have a hard time deciding which presentations I should attend...

I'll be speaking about What's new in MySQL 5.5 on Friday, 13th of May, at 15:00. If you haven't updated to MySQL

Here's an interview with Nicolas Pujol who has written an excellent new book called "The Mind Share Market."  Nicolas and I were colleagues at MySQL for several years and we often discussed the role of our free open source product as a way to gain market share in the commercial sector.  In MySQL's case, our goal was to be the #1 choice for web developers

Employee +2 Vote Up -0Vote Down

Just a quick reminder: the Oracle user groups of Finland, Estonia, Latvia and Russia are organizing a joint conference, the Harmony. It will take place on May 19th-20th in Helsinki, Finland. I've met the organizers at the IOUC summit that took place at the Oracle HQ this week and they would love to have some more MySQL content. So if you have an idea for a talk about a MySQL-related topic, please submit it! The call for papers closes on February, 1st!

Updated Drupal 7 appliances to version 7.0 final
Employee +4 Vote Up -0Vote Down

Congratulations to the Drupal community for getting version 7.0 released! This is a major mile stone and an excellent reason to celebrate!

If you want to give Drupal 7 a try without having to install anything, I've now updated my Drupal 7 appliances on SuSE Studio to the latest release. The appliance is based on openSUSE Linux 11.3 and is available in two variants:

  • A text-mode only appliance to which you connect using your local web browser via the network.

A quick summary of patch contributions included in MySQL 5.5
Employee +4 Vote Up -0Vote Down

I've been going through our bugs database to compile a list of some noteworthy patch contributions that have been included in the MySQL 5.5 release. Of course any contribution is appreciated, no matter how small! And the list is probably not complete — please let me know if I'm missing any. I omitted a number of smaller patches that fixed compile issues and I only considered contributions that were tracked in our bug database and were tagged as "Contribution".

Note that these are new patches that have not been part of any other MySQL release — of course, all contributions from previous releases are included in 5.5 as well. We also received a few patches for InnoDB (particularly by Mark Callaghan and his team mates at

Back from Lisbon, off to Nuremberg

Yesterday afternoon I returned from the SAPO CodeBits 2010 conference, which took place in Lisbon, Portugal. Just like the previous year, CodeBits has been a great conference to be at and I am grateful for having been selected for participation. Thursday, the first conference day was quite a busy one for me — I gave two presentations in a row:

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.

Drupal 7 test drive appliance updated to 7.0-beta2, now with GUI option
Employee +2 Vote Up -0Vote Down

Over the weekend I updated my Drupal 7 test appliance in SUSE Studio to the Drupal 7.0-beta2 release, which was released on Oct. 23rd. I also added phpMyAdmin upon a user request, to provide a web-based method to work with the MySQL instance, if needed.

In addition to the lightweight "headless" appliance (which can only be accessed and configured via a remote network connection), I've now also created a

The Drupal community just recently released another alpha test release of their upcoming Drupal 7 version, to shake out the remaining bugs and to encourage more users to test it.

If you would like to give it a try, but you don't have a free server handy, how about using a virtual machine instead? Using the fabolous SuSE Studio, I've created an appliance based on openSUSE 11.3, Drupal 7.0-alpha7 and MySQL 5.1 with the

OpenSQL Camp Europe and FrOSCon: A summary
Employee +4 Vote Up -0Vote Down

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

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.

BlitzDB Crash Safety and Auto Recovery
+0 Vote Up -0Vote Down

Crash Safety is a big deal in the database league. Lack of durability can lead to all sorts of terrible things upon a catastrophic event. Many projects, especially in the so called NoSQL world compromises crash safety in return for higher QPS. The argument there is that the availability of the overall system should be accomplished by replication since a database server can’t be rescued if the physical disk breaks. I happen to agree with this philosophy but I am also aware that this isn’t a correct answer for everyone. So, what will I do with BlitzDB?

Several relational database hackers have pointed out that BlitzDB isn’t any safer than MyISAM since it doesn’t guarantee crash safety. This is currently true but I plan on making BlitzDB much safer than MyISAM by providing following features.

  • Auto Recovery Routine (startup option)

    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!

    BlitzDB Concurrent Testing and Write Performance
    +0 Vote Up -0Vote Down

    Last month while being at the MySQL Conference, several people asked me about the status of BlitzDB. Specifically, they were interested in when I’ll release BlitzDB. Fair enough – I’ve been working on this project long enough for people to start questioning this.

    The answer is, BlitzDB is done in terms of implementing the design. Right now it’s about finding bugs, fixing it and testing BlitzDB’s stability under concurrent load. Thanks to the motivation boost I gained at the conference, I’ve now fixed the bugs that were slowing me down and I’m gradually adding more tests into BlitzDB’s test suite. I consider BlitzDB’s initial release to be the day it gets merged into Drizzle’s trunk. This is almost ready as BlitzDB seems to be building fine on Drizzle’s Build Farm infrastructure. However, I won’t move to the next step

    RainDB.org up for Donation
    +0 Vote Up -0Vote Down

    This time last year I obtained a domain called raindb.org which I was intending on using for my storage engine project. RainDB was the project name I had in mind for BlitzDB at the time. Since I now have a different project name, I no longer have any use for this domain.

    So, rather than letting it go to waste I’d like to contribute this domain for yet another potential open source database project. Your project can be anything – MySQL Storage Engine, Drizzle Storage Engine, Embedded Library, Stand Alone Server, whatever. RainDB would be a good name for a highly concurrent database since the analogy is – “it can be rained on”.

    If you’re interested please feel free to email, tweet, or even just leave a comment on this blog entry.

    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.

    Berkeley DB now supports SQL (again)
    Employee +5 Vote Up -0Vote Down

    Berkeley DB (BDB) is undoubtedly the workhorse among the opensource embedded database engines. It started as a university project in the mid-eighties and was further developed by Sleepycat Software, until it got acquired by Oracle in February 2006.

    I had the impression that BDB had lost a lot of its popularity among opensource developers to SQLite in recent times, which has evolved into becoming the default choice for developers looking for an embedded data store. I'd assume primarily because the code is not released under any particular license, but put in the public domain

    Thoughts about working in a distributed organization

    I've been working in a fully distributed work environment for almost 8 years now (I joined MySQL AB in April, 2002). Therefore I've been reading Toni Schneider's blog post about the "5 reasons why your company should be distributed" with great interest – he raised several points that I fully agree with and which I covered in my talks about "Working for a virtual company - how we do it at MySQL" at last year's next09 conference (slides, video) and at

    How to get your product bundled with Linux distributions
    Employee +2 Vote Up -0Vote Down

    I recently received a question from Robin Schumacher at Calpont, the makers of the InfiniDB analytics database engine for MySQL: "How would you recommend we try and get bundled in with the various Linux distros?"

    Since this question has come up several times before, I thought it might make sense to blog about my take on this.

    First of all, please note that there is a difference between "being part of the core distribution" and "being available from a distributor's package repository". The latter one is relatively easy, the former can be hard, as you need to convince the distributor that your application is worth devoting engineering resources to maintain and support your application as part of their product. It's also a space
