Jan 20, 2024 Base Python Rgonomic Patterns Getting comfortable in a new language is more than the packages you use. Syntactic sugar in base python increases the efficiency, and aesthetics of python code in ways that R users may enjoy in packages like glue and purrr.

Jan 5, 2024 Crosspost: Why you’re closer to data documentation than you think Writing is thinking; documenting is planning and executing. In this cross-post with Select Star, I write about how teams can produce high-quality and maintainble documentation by smartly structuring planning and development documentation and effeciently recycling them into long-term, user-friendly docs
Dec 30, 2023 Python Rgonomics Switching languages is about switching mindsets - not just syntax. New developments in python data science toolings, like polars and seaborn’s object interface, can capture the ‘feel’ that converts from R/tidyverse love while opening the door to truly pythonic workflows
