One more week to submit talks for the Harmony conference in Helsinki, Finland (May 19/20)

nospam@example.com (Lenz Grimmer) — Tue, 25 Jan 2011 17:29:06 +0100

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!

Bevorstehende Veranstaltungen mit MySQL-Relevanz in Deutschland und Umgebung

nospam@example.com (Lenz Grimmer) — Thu, 20 Jan 2011 01:19:00 +0100

Der Zeitplan des "MySQL & Friends" Developer Rooms auf der FOSDEM steht! Mein Dank gilt allen Vortragenden, die sich die Zeit genommen hatten, Vorschläge einzureichen. Letztendlich mußten wir eine Auswahl treffen, die Agenda ist nun auf dem MySQL Forge Wiki hinterlegt und wird auch in Kürze im offiziellen FOSDEM-Programm zu finden sein. Unter den Vortragenden sind viele bekannte Namen dabei und ich denke, wir haben ein sehr attraktives Programm zusammengestellt.

Gestern erhielt ich die Bestätigung, daß mein Vortragvorschlag für die GUUG Frühjahrsfachgespräche in Weimar im März angenommen wurde. Am Dienstag, den 24.3. um 11:30 werde ich einen Überblick über das Thema MySQL Replikationstechnologien geben. Im Slot davor wird Erkan einen Vortrag mit dem vielversprechenden Titel Baukasten MySQL halten. Ich freue mich schon sehr darauf! Auch der Rest des Vortragsprogramms sieht sehr interessant aus — ich habe viele mir bekannte Namen (besonders aus dem Sun-Umfeld) entdeckt.

Übrigens: der LinuxTag 2011 findet dieses Jahr vom 11.-14. Mai wieder in Berlin statt. Der Call for Papers geht noch bis 25. Januar. Ich habe ein paar Vortragsvorschläge zum Thema MySQL eingereicht, hoffentlich finden sie Zuspruch. Ich würde es auf jeden Fall begrüßen, wenn noch ein paar weitere MySQL-Vorträge von anderen dazukommen

Erinnerung: CfP für den "MySQL & Friends" DevRoom auf der FOSDEM endet am 26. Dezember!

nospam@example.com (Lenz Grimmer) — Fri, 17 Dec 2010 12:17:25 +0100

Nur als kleine Erinnerung: bis Sonntag, 26. Dezember können noch Vortragsvorschläge für den "MySQL & Friends" Developer Room auf der FOSDEM in Brüssel abgeben werden. Die FOSDEM-Veranstalter stellen uns für diesen Zweck am Samstag, den 5. Februar von 13:00-17:00 den Raum H.2213 (100 Plätze) zur Verfügung. Wir haben schon eine Reihe interessanter Vorträge erhalten, würden uns aber noch auf weitere Zusendungen freuen! Jeder Vorschlag rund um das Thema MySQL ist willkommen. Pro Vortrag planen wir 20 Minuten Gesprächszeit plus 5 Minuten Diskussion ein, so daß wir insgesamt 12 Vorträge halten können.

Wir freuen uns über weitere Themenvorschläge oder auch Hinweise auf interessante Referenten, die wir noch ansprechen könnten! Vielen Dank.

Reminder: CfP for the "MySQL & Friends" Developer Room at FOSDEM 2011 closes Dec. 26th!

nospam@example.com (Lenz Grimmer) — Thu, 09 Dec 2010 12:25:06 +0100

Just as a friendly reminder about what I wrote a month ago: we've already received a number of great talk submissions for the MySQL & Friends Developer Room at FOSDEM 2011, thanks to everyone who contributed so far! However, we still are looking for some more!

You can submit your proposal via this form. The deadline for turning in your talk is Sunday, 26th of December, 2010.

Just to recapitulate, the DevRoom (H.2213) will be available to us on Saturday 5th 2011, from 13:00 till 19:00. Each session will last 20 minutes plus 5 minutes of Q&A. See this year's schedule for inspiration — I think we had a great lineup of talks that addressed a good mixture of MySQL-related topics. I am looking forward to your ideas and suggestions! Thanks in advance for your support.

A quick summary of patch contributions included in MySQL 5.5

nospam@example.com (Lenz Grimmer) — Mon, 29 Nov 2010 19:23:00 +0100

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:

BUG#13175: SHA2 function (Patch contributed by Bill Karwin)
BUG#14104: FLUSH LOGS now takes an optional log_type value so that FLUSH log_type LOGS can be used to flush only a specified log type. (Patch contributed by Eric Bergen)
BUG#27249: Aliases for wildcards (as in SELECT t.* AS 'alias' FROM t) are no longer accepted and result in an error. Previously, such aliases were ignored silently. (Patch contributed by Martin Friebe)
BUG#40368: mysqld_safe did not honor underscores in the same way as dashes for server options (Patch contributed by Erik Ljungstrom)
BUG#45767: Removal of Field::pack_key, Field::unpack_key, Field::pack_cmp storage engine functions (Patch contributed by Zardosht Kasheff)
BUG#50057: SHOW PROFILE CPU port for Windows (Patch contributed by Alex Budkovski)
BUG#5724: "mysqladmin password" prompts for a password when none is provided on the command line (Patch contributed by Harrison Fisk)
BUG#26780: A new mysql client option "--auto-vertical-output", which causes the client to test whether a result table is too wide for the current window (where available) and emit vertical results in that case. (Patch contributed by Eric Bergen)

A big "Thank you" to all the contributors!

Welcome to the MySQL Community Relations Team, Dave!

nospam@example.com (Lenz Grimmer) — Tue, 16 Nov 2010 00:51:10 +0100

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.

Call for Papers: "MySQL and Friends" Developer Room at FOSDEM 2011 (Feb. 5th, Brussels, BE)

nospam@example.com (Lenz Grimmer) — Mon, 01 Nov 2010 23:25:10 +0100

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!

Drupal 7 test drive appliance updated to 7.0-beta2, now with GUI option

nospam@example.com (Lenz Grimmer) — Mon, 25 Oct 2010 22:18:01 +0200

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.

Neu im Buchregal: "Open Source Projektmanagement"

nospam@example.com (Lenz Grimmer) — Fri, 15 Oct 2010 16:56:14 +0200

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.
Michael Prokop, Initiator und Leiter des erfolgreichen "Grml"-Projekts, schöpft aus der Erfahrung, wenn er die vielfältigen Aspekte freier und zugleich professioneller Entwicklungsarbeit beschreibt: soziale Belange der Teambildung und Motivation, technische Hilfsmittel der Kommunikation und Code-Entwicklung, aber auch ganz praktische Fragen der Finanzierung, des Marketings und der Dokumentation.

Wer neue Impulse für seine Mitarbeit bei freien Projekten sucht oder als Entwickler kommerzieller Produkte Einblick in den Open-Source-Kosmos nehmen möchte, findet in diesem Buch eine wertvolle Quelle.

SL500_AA300.jpg" />

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

Testing Drupal 7 on a virtual appliance with MySQL 5.1 and the InnoDB plugin

nospam@example.com (Lenz Grimmer) — Sat, 18 Sep 2010 00:37:18 +0200

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.

Live video stream from OpenSQL Camp

nospam@example.com (Lenz Grimmer) — Fri, 20 Aug 2010 21:13:33 +0200

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.

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!
