Making Crossword Entries from Jeopardy! Before and After Clues

Before and After clues in Jeopardy! are clues pointing to two answers in which the last part of one answer is also the first part of the second answer. For example, "Supernatural kids' cartoon meets Star Wars prequel" could be a clue to both "Danny Phantom" and "The Phantom Menace", which would be shortened to "Danny Phantom Menace". 

These are a weak spot for me in Jeopardy, so I tried to make some more crosswords using only the 'before and after' clues on from Jeopardy! as found in the J-archive. It worked, sort of.

Book review: Big Data by Timandra Harkness

I picked up Big Data by Timandra Harkness solely on the testimonials of Hannah Fry and Matt Parker on the front and back covers. The 2017 printing that I read is a 300-odd page general interest book about recent advances in big data.

"Big data" starts off pretty boilerplate for the topic – with a lot of definitions about what makes data "big"; volume, variety, velocity, and the like. It also gives some historical context about the growth of data over time, through early censuses, primitive computers, to today. The rest of this book is the result of interviews across the world with people working on different big data projects.

Seasteading Economic Opportunities Overview

This is an attempt to start a conversation about different means of making a living while seasteading. From chatter online, I've heard many of the same intended sources of income: bitcoin and other crypto mining, playing the stock market, tourism, and freelance software engineering.

These strategies won't work. Not because they are bad ways to make a living, but because the supply will quickly outsize the demand, no matter how good each worker is at programming, or how amazing each oceanic hotel is. Somebody has to grow the food for all these service and knowledge workers.

In short, we need economic diversity.

Below are some seasteading-based economic opportunities, arranged by their distinct advantages.

Reversi in R - Part 2: Graphics and Custom Boards

In this post, I finish the Reversi / Othello game in R by improving the graphics, adding the ability to save and load boards, and fixing bugs. Also, many more boards have been added and tested, including those with unusual shapes, three or more players, and walls that can make the board into unusual shapes or even break it in half.

Reading questions: Struck by Lightning

The book Struck by Lightning, by Jeffery Rosenthal hits that balance of scientific correctness and approachability just right for a general audience book on probability. It’s been in print for 14 years now, and was a Canadian bestseller, so there’s nothing new that would come from a traditional review and therefore I won’t write one.

Instead, two points:

1.      It should be required K-12 or 100-level math/stats reading.

Reversi in R - Part 1: Bare Bones

In this post, I showcase a bare-bones point-and-click implementation of the classic board Reversi (also called Othello*) in the R programming language. R is typically used for more serious, statistical endeavors, but it works reasonably well for more playful projects. Building a classic game like this is an excellent high-school level introduction to programming, as well as a good basis for building and testing game AI.
