Trolling Nextdoor

Bruce Ediger

For a while in 2017 and 2018, I did a bit of trolling on

If you’re not familiar with Nextdoor, it’s a social network where your membership in various groups is based on where your residence is located. It’s been described as “stray cats and racism”, which is not undeserved.

Algorithmic Squava Players

Bruce Ediger

squava game in progress

I have four algorithms in my second attempt at writing algorithmic “players” for the game of Squava:

  1. Alpha-beta minimaxing
  2. Alpha-beta minimaxing with a better static evaluation function
  3. Monte Carlo Tree Search
  4. Monte Carlo Tree Search with UCT child selection

At this point, all but plain MCTS (#3 above) regularly beat me. How do my programmatic squava players do against each other?

New Pet

The Ediger family has a new pet!

I’d like every one to welcome…

Well Digging

Bruce Ediger

When I was maybe 11, some folks bought the hillside north of my parents’ house. The head of this new household, named Monte, had a 1940s bulldozer. He carved out the hillside to create a flat zone, maybe half an acre, for their house.

As part of putting in a dwelling, Monte and some friends and/or relatives dug a well in that flat zone.

How I learned about Bob Marley

Bruce Ediger

I grew up in Kirksville, Missouri, the largest town within an 88 mile radius. Had to go to Hannibal, or Quincy or Columbia to get to a larger town.

But I’ve also had a life-long love of Bob Marley’s reggae music.

Ordovician Extinction

Bruce Ediger

The End Ordovician Extinction seems weird to paleontologists. There’s a lot of agreement on the earth cooling at the end of the Ordovician, right up to evidence of major glaciation and a harsh ice age, but there are serious suggestions that will boggle your mind.
