I bought my first electric vehicle (EV) about a month ago and I thought it would be useful to capture my decision making around this purchase and initial impressions of driving an EV.

In this post, I briefly reflect on my experiences with NetLogo, which played a key role in my professional life.

Shiny Scorekeeper is a basketball scorekeeper app built with the Shiny web framework for R.

In my second post on this blog, I expressed an interest in learning how to build desktop applications.

In a previous post, I wrote about reading and writing JSON files in R and Chez Scheme.

When gathering with family, we like to play yard, card, and board games.

Last spring, I played in a 3x3 basketball leage with 14 teams and only 6 regular-season games.

I thoroughly enjoyed this delightful post on Kaprekar’s constant, which was new to me.

This is yet another post where I try out my dataframe library for Scheme (R6RS) on examples found in blog posts.

I recently came across this blog post that calls pandas (Python) “clunky” compared to the “silky smooth” dplyr (R).

I have been tinkering with lots of different programming languages (see here and here) over the last few years.

I have done some recent work on my dataframe library for Scheme (R6RS) and thought I would run through the examples in the Data Transformation chapter of R for Data Science (R4DS).

As a learning exercise, I decided to translate examples from the book, From Python to NumPy, into R and Chez Scheme.

As a learning exercise, I wrote a dataframe library for Scheme (R6RS).

The stochastic logistic population model described in this blog post has become my default exercise when I’m exploring a new programming language (Racket, F#, Rust).

I keep my eye out for blog posts illustrating data analysis tasks in R that I can use to test the functionality of my chez-stats and dataframe libraries for Scheme (R6RS).

I recently came across this blog post on writing simple test programs in different programming languages as a way to get a feel for a language.

I learned a lot about Scheme (R6RS) by writing a few libraries and I expect that there is more to learn by trying to use those libraries (e.g., EDA in Scheme).
