🌢️ take: I think "helper" functions are bad especially ones that are called just once. INLINE THEM!

Josiah
@josiah.rs

Then you get tests for the "helper" then you don't use the helper anymore. Now you've got tests for dead code you need to maintain. not to mention the **indirection** you need to figure outβ€”blah!

I love when @kylebarron.dev posts because i get to learn something

deck.gl-raster performs raster reprojection on the GPU. It's hard to explain, so I created this interactive explainer: developmentseed.org/deck.gl-rast...

I rarely advertise my business. I've been fortunate to receive most of my work through referrals. But I do currently have space for a short-term project! If you need help setting up data collection systems, wrangling a dataset for analysis, or documenting data for sharing, reach out! cghlewis.com

@pingfanhu.bsky.social and I built our own editor. I know, I know…does the world really need another one? But Emaki η΅΅ε·» is the tool I’ve wanted since I started using Claude Code and Codex, so we just went ahead and built it πŸ™ƒ. We’re calling it an "agentic development environment" (ADE) ...🧡

Josiah
@josiah.rs

I've got mixed feeling about Claude and agents in general, but if we can make the part **after** you build something as simple as a single sentence, that is the ergonomics I think we all need.

"help me install ricochet" The admin skill is what I'm actually most excited about. Install, configure OTEL, prometheus, etc without needing to be a Linux pro

@posthog.com you can't select multiple options in your mcp installer. I would send you a support / email but all my emails are rejected 😭

TIL of `arrow::map_batches()`: just converted 2gb of CSV files (11.2m rows) into geoarrow in 0.3s 🫒 #rstats

...also a bit of hidden @josiah.rs lore on the website. TL;DR: - shiny cannot store navigation state - shiny relies on active connections when dropped, all nav and state is lost - plumber is a full router which can serve HTML - build HTML on server with {htmltools} πŸ‘† that's called "SSR"

Love seeing @rconsortium.bsky.social grants in the wild!

Kyle Walker@kylewalker.bsky.social

tigris v2.3.0, one of the major milestones from this summer's R Consortium grant, is now on CRAN. - The package has a modern httr2 backend now, which will help the package last into the future; - New features include `population_centers()`, shown here; - The open issue count is now at zero!

Alright, #Rstats, here's the schedule for R+AI! Go register and get ready for some learning and sharing with the community! Looking forward to seeing you all online!

R Consortium@rconsortium.bsky.social

The full R+AI 2026 schedule is up! Nov 10-11. 100% online. Keynotes, talks, lightning talks, a workshop, and a tutorial. A taste: statistical thinking when AI writes the code, agents in R, private AI for sensitive data, and shipping R models to production. rconsortium.github.io/RplusAI_webs...

This is absolutely insane, I just rendered this effectively 3.1 billion triangles 900 frame 16 sample per pixel 960x540 animation in #RStats last night in 6 hours using the M1 GPU and #rayrender -- it would have taken a WEEK with the CPU renderer. Completely game changing for iterative work

e.g., a common workflow for me: rv init rv add ggplot2 dplyr [R code stuff happens] rv add tidyr forcats [more code happens] rv add ggbeeswarm and so on and so forth. Quickly plopping dependencies as I need them in the terminal while my R session remains unbothered has been pretty neat.

Guess I've been procrastianting my blog post on #rstats tooling a bit too much and @ivelasq3.bsky.social beat me to it. I't s a great overview but as someone who has been using rv a lot I feel like I need to set the record straight that you don't have to declare all deps with rv up front

{renv}, {rix}, rv, uvr, ir... so many new #RStats tools! I wrote up a blog post if you've want to unpack (haha) how they work and how they are different. Inspired by @rpodcast.bsky.social's wonderful Data Science Lab episode (thank you, Eric!). Check out the post here: rworks.dev/posts/r-mana...
