Really sad to hear about this. Michael was a great mentor to me. I knew Michael only online, but he had such a great impact on so many people, he had such a great hearth and talent. My deepest condolences to his entire family.
I'm so so sorry to hear about this. Michael was someone I only knew online, through some System Administrator discussions, but among the group of very experienced and widely knowledgeable SysAdmins that he interacted with, he stood out as being pretty much the most knowledgeable and most helpful. The online communities that he was part of are greatly diminished by his early passing.
