Understanding SwiftUI's alignmentGuide

Understanding SwiftUI's alignmentGuide modifier can be a little tricky. It might seem like objects are moving in the opposite direction of what you intend. This post should help clarify what's happening.

A programmer's Moonlander review

Okay, okay, another ZSA Moonlander review, big whoop. Many posts and videos are out there discussing the pros and cons of the board, and you may be reading this alongside those as you contemplate a purchase (they're spendy boards). My review will differ from all the others because I'm focusing on something unique: me!

Over the holiday break, I decided to be a good boy and keep up with the regular updates to this website. This website uses a Dockerized Ruby on Rails app and is deployed on Render. I had four primary things I wanted to get done:

  1. Upgrade to Rails 7.1 (from Rails 7.0)

So, I started the process of adding that functionality, and whoa baby, I coul...

Using PurgeCSS with Rails

We leverage CSS frameworks like Bootstrap or Tailwind in our applications, but we likely won't use *all* elements from the framework. This means that we’re serving larger CSS files than we need to. Wouldn’t it be great if there was a way only to include the

Copying Markdown text from Visual Studio Code

You’re trying to copy Markdown out of a .md document in VS Code and the results aren’t as you’d expect when you go to paste elsewhere. I was trying to paste it into Notion and most of the formatting wasn’t honored. Bizarre.

Turns out VS Code is trying to be overly helpful and applying syntax highlighting when we copy ...
