Quarto 1.10 shipped Friday. The highlights page lists one feature. The changelog lists 74. Mostly preview friction: stale pages, _brand.yml ignored until restart, format: changes needing two renders. If you work in Positron, that's your whole day. A boring release. Best kind.

I'm happy to share `ir`, a new command-line tool for running portable R scripts and Quarto documents. It's inspired by my two favorite parts of `uv`: self-describing scripts and tools you can run without installing first. opensource.posit.co/blog/2026-07...

ir 0.1.0: self-describing R scripts and Quarto documents

`ir` is a new command-line tool for running portable R scripts and rendering Quarto documents whose package requirements, and optional R selection, live inside the file itself.

Every time someone pastes a screenshot of a plot into their doc or presentation, an angel _loses_ its wings.

Code has gotten cheap, and that changes what's worth building. An underappreciated use of LLMs isn't the shipped app — it's the throwaway tool made mid-task, like a carpenter's jig: built to make one cut exact, not to be kept. Cheap code makes a whole new class of project worth making.

Free text has infinite ways to be wrong. A grammar or function call doesn't. That's why tool calling and SQL generation (see shiny querychat) get more from LLMs. Constrain the model to a structured response and trade an open, hallucination-prone vocabulary for a closed, testable one.

New version of quarto-shapes and quarto-revealjs-editable today! shapes now include callouts with custom anchor direction, and editable now have full shapes support! github.com/EmilHvitfeld... github.com/EmilHvitfeld... #quarto #slidecrafting

So much potential in the q2 and quartohub work! Team is killing it!

Carlos Scheidegger@cscheid.net · 2mo ago

More q2 sneak peaks (now @elliot.website and @gordonwoodhull.bsky.social's work!) this is the kind of thing we want our new preview mode to do: you can work on the preview document directly, and changes here will reflect back on your .qmd file. This will also work on the collaborative editor

I'm thrilled to share that #querychat now supports more exploratory visualization powered by #ggsql. We're excited about what this direction can unlock for data scientists looking to curate "tidy" data for others explore. Expect more on this in the coming months. opensource.posit.co/blog/2026-06...

Engineering used to be the expensive part of building products. It isn't anymore — though cheaper building won't make a spray of projects land. The bottleneck is the story: internal and to users, in their language, so the need is obvious. Always hard; now an order of magnitude more important.

Surprise I wrote another quarto revealjs extension. Now giving you more fragments to use! Easy to use fragments with conventional syntax. Works on headers, whole slides and on a letter-by-letter basis github.com/EmilHvitfeld... #quarto

I think the Turing test with real world implications is -- can an AI agent _appear_ more productive than an apathetic human in a broken system _appears_.

Amazing post on an amazing session. Thank you so much for sharing Emily!

Introducing bluffbench, a new tool to evaluate how well LLMs actually see data plots. When we trick LLMs with secret #RStats transformations, they can miss the visual contradiction. bluffbench helps us measure this "blind spot" in AI coding agents. Learn more: posit.co/blog/introdu...

When plotting, LLMs see what they expect to see - Posit

Data science agents need to accurately read plots even when the content contradicts their expectations. Our testing shows today's LLMs still struggle here.
