Quarto is amazing! And, it’s eating the world! OK. Perhaps not the entire world. But it’s still amazing! If you browse around the HQ, you’ll find many interesting notebooks.

Introducing {weatherkit}: The Eventual Replacement R Package for {darksky}
My {darksky} package has been around for years, now, and the service that powers it was purchased by Apple before the pandemic. The DarkSky API is slated to be shuttered in December of this year and is being replaced by Apple’s WeatherKit xOS Framework and REST API.

Turning {ggplot2} Into a PoS (Point-of-Sale) System
At the end of March, I caught a fleeting tweet that showcased an Epson thermal receipt printer generating a new “ticket” whenever a new GitHub issue was filed on a repository. @aschmelyun documents it well in this blog post.

A zsh Helper Script For Updating macOS RStudio Daily Electron + Quarto CLI Installs
RStudio’s macOS Electron build is coming along quite nicely and is blazing fast on Apple Silicon. I like to install the dailies, well, daily!; and, of late, RStudio and Quarto are joined at the hip.
