A dictionary of single-letter variable names
Haskell’s expressive type system means that type signatures can carry a lot of information. Haskell’s polymorphism means that you sometimes write functions that work across an enormous range of types, and are left wondering “what do I actually call my variables?”. It is often the case that there’s nothing to say…

Design Patterns Are Temporary, Language Features Are Forever
Design patterns are these cool things that make you go 'hell yeah' because they make a certain problem easier to deal with. Whether it's applicable to all languages, or due to a language constraint, they're pretty nice. Of course, some people go crazy with them rather than doing the simple thing that works. Other…

Serving a website from a Git repo without cloning it
It's fairly common to use git repositories as a vehicle for serving websites. The webdev pushes their changes to some branch of a publicly available git repository, and some web server somewhere serves the current tip of that branch as the website. Github Pages would be the most famous example of this.

Overview of cross-architecture portability problems
Ideally, you’d want your program to work everywhere. Unfortunately, that’s not that simple, even if you’re using high-level “portable” languages such as Python. In thi…

YX Problem
Software people are always all up in the XY problem: someone asks about how to do X when what they're really trying to solve is Y. I find the YX problem much more frustrating: where software people decide that they want to answer question Y even though what someone asks is question X. I've seen...

Generalizing Support for Functional OOP in R
R has built-in support for two functional Object Oriented Programming (OOP) systems: S3 and S4, corresponding to the third and fourth version of the S language, respectively. The two systems are largely compatible; however, they are two fundamentally distinct systems, two systems for a user to understand, two systems…

Algebraic effects, ownership, and borrowing
Algebraic Effects are a useful abstraction for reasoning about effectful programs by letting us leave the interpretation of these effects to callers. However, most existing literature discusses these in the context of a pure functional language with pervasive sharing of values. What restrictions would we need to…

Rails 8.0 Released
Deploying modern web apps – with all the provisions needed to be fast and secure while easily updateable – has become so hard that many developers don’t dare do it without a PaaS (platform-as-a-service). But that’s ridiculous. Nobody should have to pay orders of magnitude more for basic computing just to make…

The Functional Programming Hiring Problem
If you've ever seen a discussion of functional programming languages on the Internet, you'll have probably noticed one talking point in particular that comes up frequently. For the sake of generalization, let's make up a hypothetical functional programming language called Gooby. In these discussions, often someone…

Performance Analysis of Python's Dict() and {}
Some time ago, during a code review, I had a discussion with a colleague of mine about preferring dict() over {} in new Python code. They argued that dict() is more readable — and expresses intent more clearly — therefore should be preferred. I wasn’t convinced by that, but at that time I didn’t have any…
