#RStats challenge and potential community project: * Create a minimal package 'dumpsterfire' that triggers as many 'R CMD check' issues as possible! Fun, but could also become a excellent resource for illustrating and understanding package check issues Here's a start: github.com/HenrikBengts...
Coding agents like Claude Code feel like magic but they’re really a bunch of tools in a trenchcoat. This week I build a working coding agent in R, starting from just three tools. I’ll add some extra tools to make it safer and more efficient. tidydesign.substack.com/p/a-coding-a...
A coding agent is six functions in a trenchcoat
Coding agents like Claude Code, Cursor, and Codex have taken the software engineering field by storm. What makes them tick?

Amazonia: Brazil tourism and Futurebrand comes together to create an amazing branding and logo design based on satellite images of the Amazon river 🤩🇧🇷🌴 www.visiteamazonia.com.br/en/ #logodesign #branding #graphicdesign #illustration
Brazil launched the "Amazonia" tourism brand for one of the country's largest regions. It was made with letters composed by the Amazon river and captured from a satellite. Original post
Super excited to be launching two things today: #RustQC 🦀🧬 and rewrites.bio 🚀 I used AI to rewrite 15 RNA-seq QC tools into a single Rust binary (I've never written any Rust). It ended up being over 60x faster. Here's the story 🧵 seqeralabs.github.io/RustQC/
Welcome to RustQC
Fast quality control tools for sequencing data, written in Rust.
