I am MySQL Community Manager for EMEA & APAC. I joined the MySQL Community Team in May 2016. I have been an OpenSource and MySQL consultant for more than 15 years. My favorite topics are High Availability and Performance.

new professional perspective

For nearly 4 years, I invested myself in the growth of Inuits.

At the beginning we were 5 to believe in this project and now,
4 years afterwards, Inuits has become the Belgian reference in the world
of open-source consultancy companies.

We started in Flanders, then in Wallonia with Esquimaux and now in
the Netherlands with Eskimo (and I think it won't stop there).

Having the feeling of the achieved duty, I had opportunity of working
for a company which, for me, represents most the open-source point
of views, of technical excellence and the opportunity to spend more time with my family.

I was honored when Percona showed interest in me and I thus decided
for that new challenge! -- thanks to all my friends/former
colleagues/collaborators who played the role of references ;-) --

I whish good luck to all my colleagues of Inuits/Esquimaux,
I appreciate them very much. They can always count on me if
they need help and I hope to see them all at Fosdem and other
free software or devops conferences !!

I'm also always available for a drink or for sushi's :-)

I also really appreciated the 10 years collaboration in open-source
I shared with Kris Buytaert (sdog)

June 16th will be my first day in my new position !

Percona here I come ;-)

Google calendar support in Gnome 3 evolution ?

During my test and discovery phase of Fedora 15, I noticed that Evolution doesn't support anymore google calendar... is it on purpose ? why ?

Or do I need to install some other package ?

I found this feature in Fedora 14 something very useful !

I hope this is something that will be fixed in the final release.

In Fedora 14 (evolution-2.32.2-1.fc14.x86_64) :

In Fedora 15 :

Gnome 3 and my favorite window focus and raise behavior

Yesterday night I installed Fedora 15 Alpha to see and test the gnome-shell (gnome 3) improvements.

I stopped to test for one reason: I was not able to setup my favorite behavior for window's focus.

What I like (this is mandatory, that's also the one major reason why I don't use Mac OSX daily) is that the focus follows the mouse but doesn't raises the window !

After having "googled" a bit, I tried to install gnome-tweak-tool... but it didn't help for this task... :(

The solution is to use gconf-editor and changing the default value (click) of /apps/metacity/general/focus_mode to sloppy.

Now I'm very happy and I can continue my tests of Gnome 3.

MySQL facter

Yesterday I started to play with mcollective

I added some agents like service and facter.

I really liked the facter agent.... and then I decided to add facts for MySQL.
Of course I needed to learn some ruby first :-)

A fact is created for the version and all other MySQL facts come from the SHOW STATUS statement.

All the new facts start by mysql_

I plan to add new facts related to the replication like Seconds_Behind_Master

The current version is available on github here

Some usage examples:

with facter:

[root@delvaux facter]# facter mysql_version 2>/dev/null
5.5.10
[root@delvaux facter]# facter mysql_max_used_connections 2>/dev/null
3

with mcollective:

[root@delvaux facter]# mc-facts mysql_version
Report for fact: mysql_version
