cuplyr version 0.1.0 is now out!
A GPU-accelerated dplyr backend for R, powered by RAPIDS cuDF.
Write familiar tidyverse code, execute on GPU. Lazy eval with AST optimization.
In my benchmarks 60x faster than dplyr on 50M rows.

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!

Alex from our time working together, while he was in nursing school. Later, he moved to ICU, working as a nurse to support critically ill Veterans. He had such a great attitude. We’d chat between patients about trying to get in a mountain bike ride together. Will never happen now

2/ Polio’s cruelty lies in its biology. >90% of infections are asymptomatic or mild. Transmission occurs quietly. By the time paralysis appears in one child, the virus has already spread widely through the community. Roughly 1 in 200 infections leads to irreversible paralysis.

On tonight's All Things Considered on NPR, I discuss patients' use of AI for health. While there are risks, many patients benefit.
Overall, I favor tools that guide patients through their symptoms (with iterative Q's & A's) rather than general tools like GPT or Gemini.

The benefits of AI in health care outweigh potential hazards, many experts say
ChatGPT Health is OpenAI's foray into medicine, and so far, it gets high marks from both a cancer patient and a leading doctor. But there are worries it could be misused.
