Luca Dell'Oca, February 2, 2016January 28, 2016

Switching to a new filesystem is never a task that is done with a light heart.

I started to blog when I was already working on virtualization technologies, but before this I was a security consultant, and I still hold my CISSP certification. So, for once I’m writing something about security more than virtualization, because this news about SSL totally deserves an article. TLS is hard……
