The SSL cert for that site is comic.
1. Expired over three years ago.
2. Was issued to a different domain.
3. Issued by an un-verifiable CA.
This is a joke, right?

Great! Are there slides that we can download?
I have a couple of weeks to work on this, I can prepare the first set
of patches.
Note: I will not be at ELCE/LPC but could attend remotely or have a
call to discuss the points.
Cheers,
Jean
