From May 28th-31st, the annual LinuxTag will take place in Berlin, Germany. I followed the growth and evolution of LinuxTag from the very early days and I have fond memories of the event back when it still took place at the University of Kaiserslautern and our SuSE "booth" was just a regular table taken from the lecture rooms...

Things have evolved a lot since then. Today, LinuxTag is one of the largest Linux/Open Source Events in Europe and my new employer Sun is a major sponsor this year. In addition to several talks and keynotes, there will be a large Sun booth in the exhibition area (Booth #205) and we will have a dedicated MySQL demo pod! Some of the things we plan to demo there are the upcoming MySQL Server releases (5.1, …

I made it to the US safely, even though I almost missed my connecting flight in Heathrow (even my luggage made it, hooray!). I reached the Hotel just in time to directly head off to the traditional pre-conference party at Mårten's house. However, we just stayed there shortly (barely long enough to say hi to everybody) and then headed to the MySQL pre-conference dinner (organized by Arjen). It was nice meeting such a large number of the key MySQL community people in one place! I was especially surprised about the presence of Jonathan Schwartz and Rich Green - this added a nice touch!

Today I am attending Stewart's …

I am happy to announce the release of mylvmbackup version 0.8. mylvmbackup is a tool for quickly creating backups of a MySQL server's data files. To perform a backup, mylvmbackup obtains a read lock on all tables and flushes all server caches to disk, makes an LVM snapshot of the volume containing the MySQL data directory, and unlocks the tables again. The snapshot process takes only a small amount of time. When it is done, the server can continue normal operations, while the actual file backup proceeds.

Below is the list of changes since version 0.6. You may wonder what happened to version 0.7 - it had a rather short life cycle as I was informed about a bug that I fixed quickly before I made a wider release announcement of 0.7.

• Fixed a bug in the InnoDB recovery function: the second mysqld process …

While visiting the CeBit Trade Show in Hannover on 2008-03-06, Kaj and myself stopped by the booth of our new employer for meetings with some of our new colleagues. During our stay, they performed a short video interview with us (in German), to get our take on the MySQL acquisition and what this means to us and our users - it is now available from the Sun@CeBit2008 pages. Enjoy!

As Kaj already pointed out, the Sun/MySQL Meetup Mashup Tour will also make a stop in Munich, Germany this Friday. I will be there as well, we will meet at 14:00 at the Hilton Munich Park Hotel. Kaj and some other Sun people will join us a bit later. If you are in the area, make sure to stop by!

By the way, the Meetup Mashup Tour will make at least one more stop in Germany - I am organizing an event in Hamburg, Germany which will take place on Monday, April 7th (19:00). This was initially planned as another regular MySQL Meetup, but I offered to expand the scope a bit. We will now meet at the Sun offices, Sun will sponsor some food and drinks! In addition to …

I have not been at CeBit for quite a while, but this year I will be there as a regular visitor this Thursday (6th of March). If you would like to meet with me, please send me an email or ping me via IM/Skype! I look forward to walking around the hallways, visiting my new employer's booth and finding out what other Open Source presences and activities there will be.

Since almost a year now, we host a weekly training session for our engineers on Thursday (14:00 UTC winter time), coined the "MySQL University". While it's primary purpose is to share and distribute knowledge about a wide variety of topics relevant to our own developers, many of the sessions are of general interest for developers on other projects as well.

Therefore we hold this sessions in the public and everybody is welcome to attend! You can listen to the presentation via an OGG Audio stream, questions can be posted via IRC on the #mysql-university channel on freenode.net. The audio file and IRC log will be saved, so you can also listen to past university sessions at a later point in time again.

IBM plans a residency to write a Redbook about the IBM DB2 for i5/OS as a Database Engine for MySQL:

Like in the years before, I (and some other colleagues from MySQL) will be attending FOSDEM 2008 in Brussels, Belgium on February 23rd and 24th.

The schedule is packed as usual and lists several MySQL-related topics and sessions:

• Main tracks: Unicoding With PHP 6 by Andrei Zmievski and the talk about CakePHP by Garrett J Woodworth are certainly relevant for web developers using PHP.
• Lightning …

I’ve started working on a session on the practice of online ombuds ? especially as it applies to Free Software and Open Source communities. The session is based on my work in the Free Software, PHP, Mozilla, MySQL and Open Source communities - in particular, recent work (which I need to get back to) on the Open Source Initiative mailing lists.

So far, the session has been pitched to the following events: CommunityOne 2008 (waiting), FOSDEM 2008 (accepted), JavaOne 2008 (declined), Open Web Vancouver 2008 (waiting) and OSCON 2008 (waiting).

I’ll start posting alpha versions of slides and so on as they are ready. …
