Apparently I started writing this post in November 2016, after which I forgot about it.

I queue up articles locally, and deploy via pushing to a git repository. I'm trying to get my list of uncommitted local files down to zero, so here it is.


I watched this video of Dmytri Kleiner talking about a variety of subjects. One section in particular stood out to me, so I transcribed it.

Jump to about 41:48 for the segment in question.

Telephone Trees

So, I took another old approach called a telephone tree... I don't know if you remember telephone trees... telephone trees existed, uh, for years, before the internet. When, uh, like, schools and army reserves needed to be quickly dispatched, and it worked with a very simple topology, a tree topology. So, you had a few people that were the top nodes, that then called a list of two or three people, that then called a list of two or three people, that then called a list of two or three people... and a message can be sent through the community very rapidly, through a telephone tree.

It's often used in Canada for announcing snow days at school, for instance. If the school was closed, they would call three parents who would each call three parents, who would each call three parents, and so forth, until all the parents knew that the school was closed.

Why did this stand out to me?

Several years ago I started a bit of a personal project. I've been collecting stories about the evolution of networking in Canada, the technological developments, the needs that drove those developments, and how the resulting technologies shaped, and continue to shape relationships.
