What a sad news.
I remember I've met Drew and his lovely family on my first week I've moved to the US. It was at the Whilfest, and that was my first conference outside Brazil. Drew was one of the first speakers I saw presenting, and he blew me away. So much passion, so much fun, so much knowledge. At that time, I could only wish I'd be able to both entertain and teach people the way he did.
A few conferences later, I was presenting sessions myself, and in a few occasions I had seen both Drew and Irene sitting at the back of the room. To me, that was an honor
Drew and Brent will definitely be missed. My condolences and prayers to Irene and all the family.
