I’ll be using this space to muse about Math and coding and games, mostly.

• ## Proving My Point

What follows here today1 is my smart-ass solution to my colleague’s Problem 1.

I recently had to implement linear regression for a hobby project. As I’d never learned how to calculate it, this was a great opportunity to learn. As I dug in, I saw that I’d need to be making two passes over my data. Let’s see if we can fix that.

• ## Getting More Meaning From Your Case Classes

This will be a small post where I share some techniques we found for getting some additional type safety from our Scala case classes. We’ll look at case classes that validate their input data and we look at case classes that allow selecting from among multiple instances of the same typeclass.

• ## Denotational Semantics in a Nutshell

Wherein I attempt to give a 10,000-foot overview of semantics of programming languages.
