I have known Marc mostly from his professional side, as he was a prominent user of the open source
software I was in charge of (OpenVZ). We met in San Francisco for the LinuxWorld conference 2007,
where Marc volunteered to help with the booth. I came from Russia, and since he's local, he brought
some stuff -- a monitor, power strips, etc. After the conference he took a day to show me around --
the ocean, the redwood forest (we took a one hour hike, and he introduced the Church of Reality).
We we talked through the whole day, not just about software.

We have been in contact since, mostly professionally, he wrote a couple of articles for OpenVZ.
Despite that, I always thought of Marc as a friend rather than a colleague. For me, he is also
a prominent example of an American free thinker -- someone who is not tied to any ideology
