As part of the upcoming Oracle OpenWorld/Java One in São Paulo, Brazil next week (which will also include MySQL-related sessions), there will be a free MySQL Community event, which will take place on December 8th, from 13:00-18:00.
Here's the (translated and abbreviated) description from the events page:
Sounds like a fun event to be at — if you're a MySQL user/enthusiast and you happen to be in the area, don't miss this! You can register for the event via phone or email to the contact information given on the page cited above.

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 Google/Facebook), which were incorporated in the InnoDB plugin in MySQL 5.1 (and hence got included in the InnoDB version of MySQL 5.5, too).
Here they are, in no particular order:
Hello from Birmingham, UK! I'm here to attend and speak at the UKOUG Technology & E-Business Suite 2010 conference (what a name!) We actually have two packed tracks of MySQL Sessions this Wednesday, including a keynote by Richard Mason (Vice President of MySQL Sales and Consulting at Oracle) about Oracle's strategy and plans for MySQL as well as highly technical sessions about MySQL High Availability, Scalability and Performance tuning from experts in the field. Ronald Bradford, Oracle Ace Director and long-time MySQL community advocate will also be there, speaking about Common MySQL Scalability Mistakes and MySQL idiosyncrasies that BITE. The latter talk is actually going against my own talk about "Making MySQL Administration a Breeze - A Look Into a MySQL DBA's Toolchest". This is going to be interesting!
If you happen to be nearby, don't hesitate to come over! Admission to the MySQL session stream and the exhibition area is free! The online registration has been closed in the meanwhile, but I just learned that you can just turn up on site and the conference team will accommodate you. See you on wednesday!

It's finally official — please join me in welcoming my new/old colleague Dave Stokes, who just joined the MySQL Community Relations Team at Oracle as the new MySQL community manager for North America. Some of you may remember him from a previous stint at MySQL, where he was in charge of the MySQL certification program. Back then, he was already running the North Texas MySQL Users Group and a regular blogger on Planet MySQL. I am sure we will be seeing much more of these kind of activities from now on. So welcome aboard, Dave! I look forward to working with you.

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:To SQL or not to SQL", together with representatives from other open source databases (@fdmanana from CouchDB, @antirez from Redis and @bpedro for PostgreSQL). It was an interesting but somewhat slow discussion and the overall conclusion is still the same: there's more than one tool for a given job, choose carefully what your requirements are and don't just blindly believe the hype.
On Friday, I had some more time to attend other people's presentations. In the evening I took part in another panel discussion about Physical Computing. I also had the "opportunity" to try one of the Nuclear Tacos (Video) they served — I have never had something that hot before. Ouch! Fortunately my tastebuds recovered in time for the speaker's dinner, which took place later that evening. We went to a Rodizio restaurant nearby, the food was plenty and delicious!
Saturday was a pretty low activity day for me. I spent some time in the DIY corner, doing some Arduino hacking. Later that day I attended the project presentations and the closing keynote. Unfortunately a majority of the content was in Portuguese, so I only got parts of the content. But it was still fun! I've published my pictures of CodeBits on Flickr, I hope you enjoy them
Later today, I will be travelling to the DOAG Conference 2010 in Nuremberg, Germany. I'll be giving two talks (in German) there on Wednesday, 17th:
There will also be a MySQL Community Meetup on Tuesday, 19:00 at the Press Center of the Congress Center East. If you're around, you're more than welcome to join us there!
Next up in the conference schedule for this year is the UKOUG Conference in Birmingham, UK (Nov. 29th - Dec. 1st). We helped them with setting up a MySQL session stream, and they've created an interesting lineup of talks. I'll be speaking about Making MySQL Administration a Breeze - A Look Into a MySQL DBA's Toolchest. See you there!

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!

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 GUI-based version. This appliance starts a minimal GNOME desktop and a Mozilla Firefox browser, which in turn opens the Drupal installation page by default. I hope you will find this useful if you want to toy around and test Drupal 7 without having to go through the entire OS and LAMP stack configuration yourself. In fact, you can even test this appliance via the recently added test drive option from right out of your web browser!
The appliance is now also available in OVF format. SuSE Studio now also builds Amazon EC2 images, which don't seem to be available for download from the SUSE Gallery yet. I assume this is a recent addition to the continuously improving SUSE Studio functionality, hopefully these images will be made available soon.

Heute hat mir der Postbote Post aus Österreich gebracht: Michael Prokop vom GRML-Projekt war so freundlich, mit ein Exemplar seines Buches "Open Source Projektmanagement" (Open Source Press) zu schicken, das im September dieses Jahres auf den Markt kam. Sogar mit Widmung - vielen Dank dafür!
Ich zitiere einfach mal aus der Beschreibung des Verlags:
Die Unterschiede bei der Entwicklung von Open-Source- und Closed-Source-Software gehen weit über Fragen der Lizenzierung hinaus. Wer ein freies Projekt startet, sollte die ganz eigenen Regeln kennen, um nicht Motivation und Arbeit aller Beteiligten zu gefährden. Das heißt zugleich: Wer die besondere Dynamik bei der Entwicklung freier Software zu nutzen weiß, wird von den technischen Ergebnissen und der besonderen Atmosphäre gemeinschaftlicher Arbeit immer begeistert.
Unter der Adresse http://release-it.org/ findet sich die Website zum Buch. Das Inhaltsverzeichnis liest sich vielversprechend – ich hoffe ich habe bald Gelegenheit dazu, mir das Buch zu Gemüte zu führen.
Die Kapitel sind mit Berichten aus der Praxis und Exkursen externer Autoren angereichert und ich konnte einige bekannte Namen unter den Beteiligten ausmachen. Es war mir eine Freude und Ehre, zum Kapitel 4.1 "Team - Arbeitsformen in der Softwareentwicklung" einen Exkurs über das Arbeiten in einer virtuellen Firma am Beispiel von MySQL beisteuern zu dürfen. Zum Thema "Community Management" hat Alexandra Leisse von Nokia/Qt einen interessanten Exkurs geschrieben, dem ich voll und ganz zustimme

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 InnoDB plugin and strict mode enabled (both for the SQL mode and InnoDB mode. Using this configuration helps to ensure that Drupal works well with the current version of MySQL/InnoDB and does not use any "questionable" SQL statements. This might be especially interesting for additional modules - Drupal core did not reveal any problems using strict mode so far.
You can download disk images for VMware/Virtualbox/KVM or XEN from the SUSE Gallery (free login required). Just boot the appliance in your virtualization application of choice, choose your keyboard layout and step through the network configuration and Time Zone selection. Once the appliance has booted up and the login: prompt appeared, point your web browser to the appliance's IP address to start the Drupal installation/configuration. MySQL has been pre-configured, there is an empty database named "drupal" and a user "drupal" with the same password to access it. You just need to enter this information in the Drupal Database configuration dialogue during the installation. Anything else can be configured to your liking.
After you have finished the installation, you can toy around with a fresh Drupal 7 installation! Install additional modules, change the themes, add content. And make sure to report all bugs that you run into while doing so! Have fun.

Das verspricht interessant zu werden: im Oktober werden wir zwei eintägige Seminare zum Thema "MySQL-Hochverfügbarkeit" veranstalten, bei denen die verschiedenen MySQL Hochverfügbarkeits-Technologien und -Architekturen vorgestellt werden. Aus der Beschreibung:
Wir werden Anwendungsfälle und optimale Verfahrensweisen für die Implementierung der MySQL Replikation, von MySQL Cluster und anderen Hochverfügbarkeits-Technologien betrachten. Im Rahmen dieses Seminars erfahren Sie außerdem, wie diese Technologien grundlegend funktionieren und kombiniert werden können, um besser skalierbare und hochverfügbare Datenbankinfrastrukturen zu erstellen.
Das erste Seminar findet am 5. Oktober in Heimstetten bei München statt, am 27. Oktober wird es eine ähnliche Veranstaltung in Langen bei Frankfurt geben.
Die Teilnahme ist kostenlos - daher empfehle ich, sich früh für die Teilnahme anzumelden! Weitere Informationen findet man hier.

Wie ich schon am letzten Freitag auf Twitter andeutete, gibt es das MySQL-Referenzhandbuch nun auch im eBook-Reader-freundlichen ePUB-Format. Als Besitzer eines Onyx Boox Readers konnte ich das Handbuch zwar schon im CHM- oder PDF-Format recht vernünftig lesen, aber ePUB ist deutlich kleiner und besser auf die Gegebenheiten eines eBook-Readers zugeschnitten. Aus diesem Grund hatte ich vor Kurzem erst einen Feature Request unter Bug#56260 aufgemacht, der wohl nun als "fixed" geschlossen werden kann.
Vielen Dank an das MySQL Dokumentationsteam unter Stefan Hinz, insbesondere an Martin "MC" Brown, der die Unterstützung für dieses Format in Rekordzeit implementiert hat! Gleichzeitig wird dieses Format das betagte "CHM" (Compiled HTML Help) Format ablösen — die Hintergründe dazu finden sich in Stefan's blog post.
