Thanks to code-first, open-source tools, LLMs are REALLY good at making Shiny apps. But, how good are they at making **good** Shiny apps? 🤔 This is the sort of question that Shiny QA Engineer Karan Gathani is thinking about. And he'd like to discuss it with you tomorrow at the Data Science Lab!

R version 4.6.0 "Because it was There" (source version) has been released. It should be on CRAN by now. #rstats The choice of codename is in remembrance of R Core member Tomàš Kalibera (1978-2026). Among many other things, he was a keen mountain climber.

Last week, I had the great honor to present at the Northern Illinois University College of Business on "The Invisible Work of Data Science Projects." I am so appreciative to Dr. Biagio Palese for the opportunity. If you'd like to check out the materials: ivelasq.rbind.io/talk/invisib...
