This book have been delayed quite a bit with the problems of RTD's hosting. Things seems to be back in order so I'm able to deliver it.
This is a thing that still amaze me. The website is still working with the cheapest plan I could take at the biggest french host. The one I started with, and I've yet to receive any warning that I should upgrade. All is fine with all those visitors and downloads. I hope it continue even if I'm still trying my best to reduce the server load.
