Simple Linear Regression in One Pass
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.

The IO Rosetta Stone
Recently to a friend, I quipped that it’d be a good exercise towards demystifying Haskell’s
more...IOtype to write a comparableIOtype in your favorite language. In this blog post, I do that for Java, Javascript, Python, and Scala. -
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.

Exception Handling and I/O with MTL
This post is Part 3 of a series on type-safe failure handling. Part 1 is in Scala and examines Scala’s
more...Eitherclass as a mechanism for early-return control flow. Part 2 ports the program to Haskell, where I/O is explicitly encapsulated by theIOtype. This post will demonstrate the use of monad transformers to refactor the example from Part 2.
