For the last 2 years I have been tracking a generational change in the nature of software development, and I think I've finally decided where all of this turmoil is going to end up. It's good news, but not for everybody. seldo.com/posts/we-are-all-product-…

We are all Product Engineers now | Seldo.com
Agents are eating the software development lifecycle from the bottom up — code generation already gone, review and ops following fast. What remains is figuring out what people actually want, which can't be automated or scaled. That job is called product engineering, it pays $240k, and nobody's training for it.

Everyone else is worried about the AI apocalypse but I’ve been hearing about that for 30 years and I can’t get very worked up any more. For me the question is: If these things can code (and they can!) then why aren’t we seeing any great software? www.nytimes.com/2026/09/12/o...

New on the @posit.co blog: In my experience, fine tuning LLMs is more difficult and more expensive than I've seen it made out to be. In most cases, I'd recommend focusing your efforts on experimenting with a bunch of prompts and existing models. opensource.posit.co/blog/2026-09...

Earlier this summer, I got to share about teaching statistics with #Positron at eCOTS 2026! 💫 The video is now available to watch, and I think it was a great opportunity to reflect on how the tools we build can either support student discovery or shut it down. www.causeweb.org/cause/ecots/...
causeweb.org
Exhibitor Demo | Teaching with Positron, a next-generation IDE for statistical computing
The best moments in a statistics classroom come from discovery, when a student wrestles a messy dataset into shape, sees a pattern emerge in a plot, and genuinely wonders why. In a world increasingly shaped by AI, the tools we put in front of students can either crowd out those moments or make room for them. Positron is a next generation data science IDE from Posit, the creators of RStudio, Quarto, Shiny, and the tidyverse. It offers first-class interactive support for both Python and R and is built to keep students close to their data.

Fable 5 is the new highest scorer on bluffbench! The eval measures models' ability to accurately describe plots that show counterintuitive patterns. Six months ago, the strongest models were still in the single digits. simonpcouch.github.io/bluffbench/
A horizontal bar chart comparing AI models' performance on the bluffbench eval. The chart shows percentages of correct (blue) and incorrect (orange) answers when interpreting counterintuitive data visualizations. The best score across all models is Fable 5 (Medium thinking), around 72%. The second best scores is Gemini 3.5 Flash (High thinking), around 60%. Without thinking enabled, most models cluster around 25%.
