Kind of odd that the blog states that "The architect for ZFS at Apple had left" and links to the LinkedIn profile of someone who doesn't have any Apple work experience listed on their resume. I assume the author linked to the wrong profile?
Also can confirm Don is one of the kindest, nicest principal engineer level people I’ve worked with in my career. Always had time to
mentor and assist.
Not sure how I fat-fingered Don's LinkedIn, but I'm updating that 9-year-old typo. Agreed that Don is a delight. In the years after this article I got to collaborate more with him, but left Delphix before he joined to work on ZFS.
