Into The Fediverse!
This is more of a test post after enabling some new Fediverse features on the server. Said Fediverse got a bit more real-ish this week (with moderate apologies to the pioneers in this space who’ve languished for ~five years) You can find me at: @hrbrmstr@mastodon.social (general blathering/primary masto-account) @hrbrmstr@infosec.exchange (res...

Bootstrapping An {ojs} Quarto Document With An Observable Notebook

You may even have a few yourself! Wouldn’t it be great if you could just import an Observable notebook right into Quarto? Well, now you can. #' Transform an Observabl...

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. It’s a pretty cool hack, self-contained on a Pi Zero. Andrew’s project birthed an idea: could I write an R package ...

Update On ESC/POS Package Work
The morning before work was super productive and there is a nigh-complete DSL for ESC/POS commands along with the ability to just print {ggplot2}/{grid} object. I changed the package name to {escpos} since it is no longer just plot object focused, and the DSL looks a bit like this: library(stringi) library(hrbrthemes) library(ggplot2) library(esc...

Keeping Those SSH Keys Safe
I came across a neat site that uses a Golang wasm function called from javascript on the page to help you see if your GitHub public SSH keys are “safe”. What does “safe” mean? This is what the function checks for (via that site): Recommended key sizes are as follows: For the RSA algorithm at least 2048, recommended 4096 The DSA algorith...

Rusty HTML Minifying In R with {rextendr}
In my M-F newsletter today I mentioned an awesome Rust-based HTML/JS/CSS minifier library that also include batteries for a few other languages. There was no R port, so I made one using {rextendr}. The {rextendr} package makes is as easy to use Rust code in R packages as {Rcpp} does C/C++ code. It was as simple as adding some dependencies to the ...

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. I’ve started work on a {weatherkit} package which uses the WeatherKit REST AP...

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. As a result, I regularly found myself having to manually update Quarto CLI right after updating RStudio, so I made a small zsh script that will use...

ThinkStats … in R (including Example 1.2)
ThinkStats (by Allen B. Downey) is a good book to get you familiar with statistics (and even Python, if you’ve done some scripting in other languages). I thought it would be interesting to present some of the examples & exercises in the book in R. Why? Well, once you’ve gone through the material in a particular chapter the “hard way”, see...
