Custom Hexagon Shape in SwiftUI

Flowing Text Around Images

Magazines, books, and other print layouts sometimes use images that overlap with the text, and have that text wrap around the shape of the image. It can make for an interesting effect, bringing a feeling of motion into a static medium. Done right, the text and image become conceptually closer in...

CSS-only Submenu Navigation with Post Tags

Our posts have categories, which I’ve used as a “collection” or “series” of posts that are on related topics. Recently, I’ve been writing up campaign notes for my D&D session as the characters themselves in a category simply called Campaign Logs. I’m also hoping to continue to write this type...

A Site Reborn

I’ve moved my Jekyll site into a Rails app, and I’ve done just enough work to have every post render without errors and added just enough style to make things readable. Some of the site still looks pretty bad, and none of it looks good yet. But that’s ok, because my plan is to rebuild and...

Multi-table Full Text Search in Postgres

Easily searching across an application’s data is a pervasive need. If you are lucky, you can get away with simple sorting or searching on a single column, but it is more likely that you need full text search across multiple models, all from a single search <input>.
