I’m giving two talks tomorrow (Tuesday) at the MySQL Conference and Expo:

HailDB: A NoSQL API direct to InnoDB, 2:00pm, Ballroom D

Dropping ACID: Eating Data In A Web 2.0 Cloud World 3:05pm, Ballroom G

The HailDB talk is all about a C API to embed an InnoDB based relational database engine into your application. Awesome stuff (also nice and technical).

The second talk, “Dropping ACID: Eating Data in a Web 2.0 Cloud World” is not only a joke that only database people get, but a humorous and serious look at data integrity and reliability as promised by the current hype. This was quite well received at linux.conf.au in January. So, if you weren’t in Australia in January this year, then certainly come along and see how you go heckling an Australian.

I'll be speaking the next PHPBenelux meetup in Amersfoort about implementing WebDAV using PHP. Joshua Thijssen will also be doing a talk about MySQL optimization. The meetups are free, so if you have some time after work, drop by and say hi. You can sign up at the PHPBenelux site.

At the upcoming MySQL Conference and Expo, I’m going to give a Thursday afternoon (2pm) session entitled Fixed in Drizzle: No more “GOTCHA’s”. I plan to have a lot of fun with this session..

If you go back to the very start of when I started submitting code to Drizzle (June 2008) – I was going and fixing some of my favourite “gotcha’s” inside the code: BUILD/ scripts that didn’t build the way releases would, wrappers on POSIX functions with different (and inconsistent) semantics, NETWARE support, a non thread safe client lib,

Here are the slides from my talk at Open Source Days 2011 on Saturday. The talk was about MariaDB and other parts of the MySQL development community outside of MySQL@Oracle.

For me, the most memorable part of the conference was the talk by Noirin Shirley titled Open Source: Saving the World. Noirin described the Open Source Ushahidi project and how it was used during the natural disaster crisis in Indonesia, New Zealand and other places.

Now, there is a long way from implementing group commit in MariaDB to rescuing injured people out of collapsed buildings, and not all use of Free Software is as samaritan as Ushahidi. Well,

Again this year, I will be speaking about MariaDB and stuff at the OpenSourceDays2011 conference in Copenhagen, Denmark. The conference will take place on Saturday March 5, that's just over a week from now! The program is ready and my talk is scheduled for the afternoon at 15:30. Hope to meet a lot of people there!

(I will be sure to make the slides from my talk available here afterwards, for those of you interested but unable to attend.)

Here is the abstract for my talk:

Latest news from the MariaDB (and MySQL) community

A lot of Open Source software projects got transfered to Oracle last year as part of the acquisition of Sun Microsystems. Not everybody in the affected Open Source communities have been happy with this transfer, to put it mildly, and projects like

There’s a good number of videos appearing online from the MySQL Conference and Expo that was on last week.

Here’s a short list of interesting things to look at if you weren’t able to make the sessions. Obviously, this is from my view as a Drizzle developer. There were other interesting things, but this list is more focused towards where my Drizzle brain is stimulated.

• State of Drizzle (Brian Aker)
• MySQL at Facebook (Mark Callaghan)
• High Concurrency MySQL (Domas –

I would like to point the crowd to the Call For Presentaions of Loadays. , the Linux Open Administration Days .

The Linux Open Administration days 2010 will be the first edition of a new conference focusing on Linux and Open Administration, we are trying to fill a gap for System Engineers and Administrators using Open Source technologies"

More details on the Linux Open Administration Days site

I'll probably be there .. given the fact that the event will be 5 minutes from where I live .

In case anyone is interested in a copy of my slides for the two lightning talks I gave at the Open Source Days 2008 conference, I have made them available here:

• "Optimizing Large Databases Using InnoDB Clustered Indexes:" HTML and PDF.
• "Profiling with OProfile and Intel Core 2 performance counters:" HTML and PDF.

I waqs quite pleased with the benchmark that I prepared for the InnoDB mini-talk, where I measure the performance difference between clustered and auto_increment

• Baron Schwartz's advice on how to write a great proposal. If you follow these guidelines, you can't be wrong.
• Colin's list of 10. If you still had doubts after reading Baron's post, this one will clear your

Last week I gave my first webinar for MySQL (http://www.mysql.com) titled “Bau sicherer LAMP Anwendungen”. The webinar, which was a cooperation between MySQL and my company SektionEins, was held in german, covered SQL-Malware, SQL-Injection, safe programming and some tools to detect and block SQL-Injection attacks.

The recording of this webinar is now available (http://www.mysql.de/news-and-events/on-demand-webinars/display-od-171.html) on the MySQL site.

For those that only want to see my slides they are available on the MySQL site after registration or here.

Because it was a german webinar the recording and slides are in german, too.

Last night I spoke at Lehmanns book store in Hamburg on the new ext/mysqli extension in PHP 5. The talk was a good deal of fun and provided a nice warm up for the upcoming three hour tutorial that Georg and I will give at ApacheCon EU. (Additionally, some sharp audience members caught errors on my slides! :)

Thanks to everyone who attended (about 50-60 people, even though the weather in Hamburg was absolutely fantastic and the talk was in English, rather than German.)

In particular, thanks to Ekkehard Doerre from coolscreen.de and Dirk Eckel from Lehmanns for coordinating the talk.

The setting for the talk - the Lehmanns in Hamburg near the Hauptbahnoff

Thanks to coolscreen.de / Ekkehard Doerre, I will be presenting to the Hamburg PHP User Group on ext/mysqli and the new features of MySQL.
