Hello readers!
The numbers of readers keeps growing and I really appreciate it :-). Thanks to all followers!
You may know that I’m currently writing a book on MariaDB performances/high availability. I’m almost finish and this is the last run before the publication in September.
To give the maximum in this book , in the very short delay I have to, I need more time. The current blog post flow is: one blog post every 2 days.
And the thing has finally happened! In recent years,the idea ofone day workingat Red Hatpleases me.As you may know, I’m working at eNovance and the news is: RedHat has acquires eNovance! So I belong now to Red Hat family :-). RedHat really wants to to have our OpenStack experience and I’m excited to work with other teams like Ceph (ex Inktank).
I really hope it will be an excellent adventure and will enjoy it.
I really like this kind of news, new versions of docker and RedHat:
Docker 1.0: this is the first stable version after more than one year of development. This version is production ready and I will start using it asap. RedHat 7: this is a good news as the version 6 started to be a little bit old now. What’s new? MariaDB replace MySQL \o/ Docker integrated systemd XFS by default Kernel 3.

Do not miss OpenStack meetup event at eNovance headquarter! There will be big talks on:
ZFS Ceph Swift You’ve understood, it’ storage related for OpenStack.
Of course I’ll be there :-D. More informations are available here.
I recently upgraded the wiki to version 1.23 (new LTS version). As usual Mediawiki made a very good work, no problems during migration using Git, everything is working.
No major visual changes between the previous version 1.22 and this one. I didn’t had to touch anything on my JS, CSS or configuration! Great!
I encountered an issue with my GoogleSearch extension and made the changes to make it work again. So a new version (0.
I recently migrated this server to a new one. New hardware, better performance, less power consumption etc…Thanks Online.
I’m already using LXC on my home server and see the benefits for 8 months ago. That’s why I decided to migrate this server to LXC as well. The difference here is that I wanted to migrate my VM from KVM. All my KVM VM are on Debian Wheezy so that was pretty easy.
