Zero, One, or Infinity
An interesting tidbit from a NANOG/DNS post:
"But needing “multiple” DNS Root Zone Servers and coming up with the number 13 appears to be somewhat curious. It seems such an odd limitation in the number of root servers given that a common rule of thumb in computer software design is Willem van der Poel’s Zero, One or Infinity Rule, which states a principle that either an action or resource should not be permitted (zero), should happen uniquely (one) or have no arbitrary limit at all (infinity). For root servers, it appears that we would like more than one root server. But why set that number to 13?"Leading to:
"The desire in the design of the DNS priming query and response was to provide the longest possible list of root name servers and addresses in the priming response, but at the same time ensure that the response was capable of being passed in the DNS using UDP. The largest possible set of names that could be packed in a 512 octet DNS response in this manner was 13 such names and their IPv4 addresses - so there are at most 13 distinct root name servers to comply with this limit."

Nuance for Novelty
I was listening to the Freakonomics podcast on "grit" and this really struck a chord with me:
"But I will say this: it is human nature to get bored of things and to seek the novel. And I think that one of the skills that one must develop in life, if one cares not to be a dilettante, if it’s a goal of yours to become expert in something, one of the skills is to learn to substitute nuance for novelty."
Happy Valentine's Day!
Happy Valentine’s Day, my dearest. I look forward to working you tonight. #hamentine— Ham Hijinks (@HamHijinks) February 14, 2017

Dragon Magazine
I saw this post at the Ace of Spades and it reminded me of my younger days reading Dragon Magazine.
And, of course, I had to Google "Dragon Magazine" and I found this site, rpg.net which has all the covers and details of each issue. It is unreal the information they've cataloged there for each issue.
