Posit
R is capable of many analyes in the world of data science, but can it build a computer? Also a massive usability feature landing in the latest bslib to…
Personally it's a great one for me as test coverage is back at 100% again after quite some time - not a single line missed. This speaks to the origins of mirai - it was built for robustness (which necessitated simplicity, and performance came as a side-product).
Announcing mori 0.1.0: Zero-copy shared memory for #RStats!
Parallel R usually means duplicating data across every worker, causing RAM bloat.
mori fixes this by sharing R objects across processes via OS-level shared memory. Share once, read anywhere

mori is a new R package for sharing R objects across processes via OS-level shared memory. Parallel workers get zero-copy, lazy ALTREP access to the same physical pages — share once, read anywhere.opensource.posit.co
I've just tried Posit Assistant on the free plan and must say, I'm impressed. Using the super-cheap Gemma 4 26B model (10% cost of Sonnet) on free plan it worked instantly. Hats of to the #posit team for integrating this into RStudio and allowing people to test with free plan!
Btw. did you know that you can use the mori package to avoid copying large objects to (or from) the subprocess? github.com/r-lib/callr#...
I just released nanonext 1.9.1 - which strips out old dispatcher code paths to make mirai >=2.7.0 even faster! If you're using nanonext with mirai, please make sure you're on at least mirai 2.7.0 before upgrading. #Rstats #Tidyverse

🚀 mirai 2.7.1 is out!
async/parallel/distributed computing for R, minimalist as ever.
Now bundles its agent skill so `btw` and friends pick it up automatically. Lower overhead for sync daemons, flexible HTTP headers in `http_config(), and nice bug fixes.
