"This is bad. Why haven't you fixed this yet? I would have already fixed this today with Claude code." -- @wesmckinney.com on radical accountability for software vendors. #AIcodingagent #DataRenegades

@wesmckinney.com is on an absolute tear. 🔥 The pandas creator is leveraging AI to rapidly ship tools, crossing Swift, Go, and Python to build Agents View, VibePulse, roborev, moneyflow, msgvault, Spicy Takes... @richmeister.bsky.social breaks it down on the Posit blog: posit.co/blog/the-pro...

The Prolific Output of Wes McKinney in the Age of Agentic Engineering - Posit

Wes McKinney is shipping open source projects faster than ever, using AI coding agents to build across Python, Go, Swift, and Rust... and he's having more fun than he's had in years.

"Working with agents is a lot more productive, but a lot less fun." Charlie Marsh on the weird world of building software right now. Full conversation on The Test Set.

roborev does GitHub now! Just shipped the initial GitHub PR experience, multi-agent / multi-prompt reviews that synthesize to a single coherent review response: www.roborev.io/integrations...

GitHub Integration

Automatically review GitHub PRs and post results as bot comments

roborev.io

Had a great time on @posit.co 's Test Set pod w/ @mchow.com @hadley.nz @wesmckinney.com! We talk about moving between R, SQL, python and the strengths of different analytical tools for diff data tasks. You won't believe what proprietary language gets a shout-out (Stata!) posit.co/thetestset/e...

roborev can now analyze and systematically refactor your code for you — this is essential to managing the poor code quality of agents in rapidly expanding agentic code bases. Game changer for me www.roborev.io/guides/assis...

Code Analysis and Assisted Refactoring

Run built-in code analysis and automatically apply fixes with roborev analyze and roborev fix

roborev.io

roborev now supports Windows (x64 and ARM)! Lots of new features and quality-of-life features, too (such as `y` to copy-paste/yank review to clipboard to paste into your agent session) www.roborev.io/installation/

Installation

Install roborev on your system

Any now there were 14. Welcoming @joereis.bsky.social to Spicy Takes! joereis.spicytakes.org

A funny thing is happening: the more I build with agents, the less I want to use Python. I explore this in my latest "From Human Ergonomics to Agent Ergonomics" wesmckinney.com/blog/agent-e...

Join Wes McKinney (@wesmckinney.com) and the Pixeltable @pixeltable.net team, Marcel Kornacker and Alison Hill (@apreshill.com), for a fireside chat hosted by Hugo Bowne-Anderson on Dec 16! They will discuss data processing and #AI workflows for multimodal data 📊 Register: luma.com/2y04b6nf

Building Multimodal AI Workflows with Pixeltable · Luma

The challenge with multimodal AI isn't calling models. It's everything else. Videos need to become frames. Audio needs transcription. Embeddings need to stay…

Super interesting @wesmckinney.com insight: AI may stagnate Open Source - because users will be much more inclined to adopt software that AI tools can help them with, rather than newer tools that it isn't trained on yet. Kind of a "snake eating tail" problem as far as generating new training data.

“Parquet is great… until GPUs, multimodal data & million-column schemas show up.” The creator of pandas/Arrow @wesmckinney.com digs into Arrow vs Parquet, new columnar + table formats, DataFusion/DuckDB, metadata headaches, and what AI coding agents mean for open source infra. Episode link below
