本日の #TokyoR で、mizu のワールドプレミアをお届けしました！主役はミズちゃん💧 mizu は、ロックフリーな共有メモリで、同じマシン上のRプロセス同士をつなぐパッケージです。同じCコアのPython版 pymizu もあるので、RとPythonでチャネルを共有できます。プレリリースなのでAPIは変わるかもしれません。ぜひ試して、感想はGitHubへ！ github.com/shikokuchuo/...

Come join me at posit::conf(2026)! We're almost there (Sept 14-16). I'm speaking in the 'from laptop to cluster' session on scaling further and scaling safely for Shiny and other R production workloads. There's a page for everything that's happening: conf.posit.co/2026/sessions/ #Rstats #Rshiny

Until next time! It's been a fantastic #useR2026 in Warsaw. Honestly, there's a real depth to the talent we have in our #Rstats community. Keep doing your amazing work and wow us all at the next conf! (can you spot me here?)

It's always nice to re-connect with old friends, but some of my best conversations at #useR2026 this year have been with people I'm meeting for the first time. For many of them this is their first useR!, even if they've been doing #Rstats stuff for a number of years. I also spoke about CRDTs today!

#Rstats really is a great community - I'm surprised by how many ppl I know through past events. It's been so great catching up with you all - everyone I've spoken to thus far. Also delighted to be meeting some people for the first time! #useR2026 opening reception a success, onto the first conf day!

And that means you no longer have to choose between convenience and correctness. Don't want to identify and specify your dependencies by hand? Let Claude do it for you. You get the robustness of mirai's model with the ease of pointing at your code and saying "use mirai to make this parallel".

mirai 2.5.1 released. mirai.r-lib.org This is a patch release, but brings a new synchronous mode: `daemons(sync = TRUE)` runs your code in the same process. This means you can now drop into a browser session *within* your mirai #rstats code! p.s. amazing hex stickers made by someone @posit.co!!

I'm hoping you'll join our session on Strengthening the R Ecosystem at posit::conf(2025) on the Thursday morning! Find out about the hottest new thing in the tidyverse: "purrrfectly parallel, purrrfectly distributed" (yes, it's something about cats). #rstats #tidyverse #PositConf2025 pos.it/conf

I'm speaking at posit::conf(2025) in Atlanta Sept 16-18

New in #rstats R4.5.0: `parallel::makeCluster(6, "MIRAI")` creates a parallel mirai cluster with 6 nodes. Yes that's right, mirai is now officially a base R cluster type! mirai.r-lib.org Result of work from the R Project Sprint in Warwick 2023 in collaboration with Luke Tierney (R Core).

mirai is now an 'enhances' package of the base parallel package

ShinyConf Friday, 11 Apr 2025 1:40 pm - 2:00 pm EDT I'll be covering Shiny with mirai, and how that now extends easily to distributed computing. See you all there! mirai.r-lib.org #rstats #rshiny #ShinyConf2025

A glorious day here in Cambridge! Just released mirai 2.2.0 from the Centre for Mathematical Sciences (CMS). Simplified distributed computing using SSH tunnelling, mirai_map promises, and lots of new and updated ✨ Shiny ✨ vignette examples to check out! github.com/shikokuchuo/... #rstats #rshiny
