My wife isn’t the woman I married

A couple that lives near me has been having problems, and yesterday the husband asked if he and I could talk privately. After we found a quiet place he said, “My wife isn’t the woman I married ... I don’t like this new version of her, and I don’t know what to do.”

(Sorry, there’s no moral to this story, only that.)

Truck drivers may need a new trade

When I saw this map after the election I didn’t think about politics. I thought, “Wow, in ten years almost all of those truck drivers can be replaced by self-driving vehicles.”

How to create an Array whose size can change (ArrayBuffer)

This is an excerpt from the Scala Cookbook (partially modified for the internet). This is one the shortest recipes in the book, Recipe 11.8, “How to Create an Array Whose Size Can Change (ArrayBuffer)”

Problem

You want to create an array whose size can change, i.e., a completely mutable array.

Solution

An Array is mutable in that its elements can change, but its size can’t change. To create a mutable, indexed sequence whose size can change, use the ArrayBuffer class.
