I barely "promoted" anything this summer thanks to "The Business™", but I'll be presenting "Fake it Til' You Make It: Mocking Reality So Your Tests Can Run" at posit::conf(2026) this Wednesday in Houston! Say hi if you see me! Not sure if it's me? Look for the purple and pink hair! 🤸🏾‍♀️💜🩷

My talk “Fake it Til' You Make It: Mocking Reality So Your Tests Can Run” was accepted for #positconf2026 🎉 A software testing focused talk this time, and a reflection of where I’ve been putting my energy lately: Python, AWS, testing, and engineering flavored work. Excited for this one!

When it comes to #Python type checkers and LSPs, we had a lot of options for what to bundle in Positron, our data science IDE! 🤯 Read through how we evaluated Pyrefly, ty, Basedpyright, and Zuban, and what we ended up deciding to use by default: positron.posit.co/blog/posts/2...

How we chose Positron’s Python type checker – Positron

We tested four open-source Python type checkers to find the best default for Positron. Here’s how Pyrefly, ty, Basedpyright, and Zuban compare on features, correctness, performance, and development ve...

dplyr 1.2.0 is out now and we are SO excited! - `filter_out()` for dropping rows - `recode_values()`, `replace_values()`, and `replace_when()` that join `case_when()` as a complete family of recoding/replacing tools These are huge quality of life wins for #rstats! tidyverse.org/blog/2026/02...

dplyr 1.2.0

dplyr 1.2.0 fills in some important gaps in dplyr's API: we've added a new complement to `filter()` focused on dropping rows, and we've expanded the `case_when()` family with three new recoding and re...
