Regardless of which editor I’m using, it’s common for me to change the font size depending on whether I’m using my MacBook Pro’s Retina display or the non-retina 27” Thunderbolt Display at my desk. It’s a small thing, but, when I started using Emacs, one of my biggest annoyances was the amount of friction involved in changing its font size. Here’s how I fixed that.

Six Editor Features You Shouldn’t Live Without
When it comes to my choice of editor, I find that I’m a nomad. I’m always switching around based on the needs of my current project and the editor I’m using. If I squint hard enough, VSCode starts to look like Emacs. Over time, I’ve found a few editor features I can’t live without. Read more on Six Editor Features You Shouldn’t Live Without…
12 Emacs Keybindings Worth Learning

Easily Reloading your Clojure Project in Spacemacs
I’ve long been a fan of Stuart Sierra’s reloaded workflow. When I’m working on a ClojureScript project that doesn’t use Figwheel or another tool to assist with live code reloading, this is the pattern I reach for to help manage iterative and interactive development.

Exporting Application Data for Business Users? Use XLSX, Not CSV
Having written my fair share of application data exports and imports, using CSV for tabular data has usually appeared to be an obvious choice. But lately, I’ve changed my mind on this. I’d argue you should write XLSX instead. Read more on Exporting Application Data for Business Users? Use XLSX, Not CSV…
What is Point-Free Notation & When Does it Make Code More Readable?
Like most fancy-sounding development terms, “point-free notation” actually isn’t that complicated. The “point” refers to the name of an argument for a function. Let’s say you have the following function: Read more on What is Point-Free Notation & When Does it Make Code More Readable?…
Understanding UIAppearance Container Hierarchies
I recently had my first run-in with the UIAppearance infrastructure that has been built into iOS for, admittedly, a long time. Given my experience with CSS, I brought along some assumptions of how appearance(whenContainedInInstancesOf:) would probably work. Naturally, these assumptions were very wrong.

(Clojure) Spec-ing Data from JSON
I’ve returned to Clojure after some time using other tools, so I’m late to the party regarding learning and experimenting with Spec. The first order of business was to build some specs for data I’m receiving from an external system in JSON format. Given that it was my first real experience with Spec, and I had no control over the shape of the data I was spec-ing, I was uncertain how to proceed. Read more on (Clojure) Spec-ing Data from JSON…
Control Flow in Ruby Blocks
I recently found myself needing to return early from a block passed into a method in Ruby. Although the way to do this is fairly simple and obvious in hindsight, it seemed to surprise some of my Ruby-enthusiast colleagues. I decided to write this post in the hopes that it’s interesting to others. Read more on Control Flow in Ruby Blocks…
