Now that FOSDEM 2009 in Brussels, Belgium is over, it's about time for a conclusion/summary. I've been to FOSDEM for about five times as both an attendee and speaker, but this year I was much more involved. On Saturday, I gave a lightning talk about "Why you should use Bazaar for maintaining your OSS project". On Sunday, I gave a talk about "MySQL High Availability Solutions" in the main conference track. Both went fairly well and there was good feedback from audience. I've uploaded the slides for both talks to the FOSDEM 2009 page on the MySQL Forge Wiki, video recordings of the sessions should be available on the …

Today I gave an introduction talk of MySQL Cluster at FOSDEM 2009 in Brussels. The room was full and I didn't see anyone dozing!
A good feedback later on was to show more usecases. This a good point and I think on working on a talk showing less how it works, but how it can be used. Doing both technical details and use-cases is hard to do in 50 mintes.
I feedback is appriciated!

BTW, slide will eventually come online somewhere..

Given the changes announced this week, I have updated my original plans for my presentation on Sunday. I was going to talk about Social networking, but am now changing it to a very interactive Q&A session.

I expect people are asking themselves

• What has changed?
• What will happen now?
• What are the consequences for the MySQL roadmap?
• Are there other consequences for the MySQL community?

and I will attempt at answering these questions interactively during FOSDEM.

Towards the end of next week, after internal coordination, I plan to share some further thinking on the “what will happen now” front with my blog readers.

What also I plan to do during …

All of us here at Percona warmly invite you to Percona Performance Conference 2009 on April 22 and 23, 2009 in the Hyatt Regency in Santa Clara, California. The theme for the conference is Performance Is Everything. This conference is about application performance overall, not just databases. Attendance is free of charge for everyone. Experts in many types of technologies -- databases, search, cloud computing, massively parallel computing, client-side optimization -- will present their real-life experience.

In order to forestall speculations and prevent people from jumping to unwarranted negative conclusions, I'd like to take a moment and explain the story behind this event. Some of you have noticed that there were no sessions from Percona this year on the schedule for the …

When I read Monty's post on leaving this passage struck me the most.

The main reason for leaving was that I am not satisfied with the way the MySQL server has been developed, as can be seen on my previous blog post. In particular I would have like to see the server development to be moved to a true open development environment that would encourage outside participation and without any need of differentiation on the source code. Sun has been considering opening up the server development, but the pace has been too slow.

In short, Sun isn't open enough. I think I've said that enough, it's typically more Open Core than Open Source .. and for a growing amount of people.. that isn't good enough.

Reacting on that post we see Matt Asay …

There are some basic, golden rules when it comes to having a vibrant community of contributors.

The following are rules I have extracted and learned based on my experience managing and working with engineers actively involved and participating in the Apache/Derby, PostgreSQL and MySQL open-source communities. These rules are also based on extensive discussions with many folks involved with the MySQL community, with the PostgreSQL community and with the Apache/Derby (Java DB) community, over many years.

Before I go through these rules, I would like to thank Marten Mickos for having suggested some of the headings for these rules. (I originally had much longer headings for all of them.) I would also like to thank many of MySQL, PostgreSQL and Java DB colleagues, as well as to many other colleagues involved in open-source development, for having contributed to the ideas and practices behind these rules.

John Lilly, CEO of Mozilla, shares some insights and thoughts on Mozilla, and its a most interesting presentation to go through. The insights are (drizzled with some of my comments):

1. Superior Products Matter - Without excellent experience and utility, the rest is meaningless. This is true, even with MySQL - our aims and values have always been performance, reliability and ease of use.
2. Push (most) decision-making to the edges - I understand that as make sure your community has a significant voice (kind of like Wikipedia’s anyone edits policy, but there’s patrolling). He also suggests that on a regular basis, you need to have surprising innovation - things that blow people’s minds. In Mozilla’s case, there are a set of core values that everyone agrees too; …

I was looking for some info on liveblogging art this am because I never did a similar activity and was wondering if I am able to do it in the next confs I’m gonna taking.

Liveblogging means taking notes about a conference session you are listening and share the main concepts of the talk with people who are not present in the room.

I’ve found some tips on how to start a successful liveblogging session and tested a cool platform: http://www.coveritlive.com.

You know, liveblogging at a conference is very important for people who can’t attend it. It helps, among with pics and videos, to smell the great atmosphere you can breathe in a community event.

I think things are evolving well from this side.

If I am not mistaken, the most easy way to liveblogging is to create a short blog post during the speech and publish it at the conclusion of the …
