If you've been thinking about submitting a talk for posit::conf(2026), but you're a little nervous about the process, I have the ~15 min video for you! youtu.be/aKN8qlLjld4

What is it like submitting an abstract for posit::conf()?

Have you also been noticing the many anecdotal reports of folks burning out on Claude code in their evenings and weekends? Like it’s fun but additive and easy to get sucked in.

I really hope that this comes to pass
it is already possible, right now, to get 100tok/sec out of 100 watts of air-cooled local inference, and the output is surprisingly good

LLM architecture gains will compound against improved silicon over the next five years to produce serious leverage, WHICH WORKERS CAN OWN OUTRIGHT
If you're a person who thinks "billionaires are evil -> billionaires own big tech -> frontier labs dominate the LLM space and are owned by billionaires -> LLMs is evil" then I am sympathetic to it. However the correct prescription is not to destroy LLM technology but to expropriate it.

What stops you from using ragg like positron does?

I built an R package that turns Shiny apps into UIs that render directly inside Claude Desktop or ChatGPT.

It's called shinymcp. Drop-downs, plots, tables all inline in the chat.

It's easy to feel overwhelmed by the current pace of change in technology.

A useful counterpoint:

There are STILL organizations using ArcMap for their GIS even though ArcGIS Pro has been out for over a decade.

Technology moves fast; capacity for adoption, not always.

When you're editor of stuff you get to see the chaos of your colleagues' file-naming conventions, and what a gift that is.

My reading of the documentation implies only within the project directory and I’ve never seen it outside without explicitly asking permission. But that said it feels like the permission system is vibe coded and has a lot of unusual behaviour (but mostly erring on the side of caution)

WTF
US women are more likely to be murdered during pregnancy or soon after than the 3 leading obstetric causes of death: hypertensive disorders, hemorrhage, sepsis. From 2018 to 2021, pregnant women had a 37% higher firearm homicide rate than nonpregnant women. healthjournalism.org/blog/2026/02...
Firearm homicide rates higher among pregnant women than nonpregnant women, study shows
U.S. women are more likely to be killed during or soon after pregnancy than the three leading causes of maternal death, study shows.

So much great advice in this thread!
I've been in SF for four days and on each day I've had multiple conversations where people (self included) express deep feelings, fear, wonder and worry about their skills being replaced or (this is less named explicitly but an assumed driver I think) no longer valued by others. Big threats to feel

inspired by CLAUDE.md, I’ve started putting markdown files named after coworkers into work code repos so I can remind them to stop doing shit to the codebase that annoys me

for some reason they’re all mad at me now, which means ill be adding commands to JEREMY.md for an attitude adjustment

I think people often wonder this, and it's a great question, so let me explain the advantages of 3D printing whistles. There are many.

The 3D printing effort started from one of our organizers who started by sourcing mass-produced whistles.
I mean, are they really cheaper or easier to produce than just sourcing the right thing from a mass distributor? it's sweet but doesn't seem Pareto efficient, and I feel like that's important to the revolution

Folks, have you been overwhelmed by ~All This~ and wanting a gentle compassionate space to think about agentic coding??

Good news: if you're in SF & have free time tomorrow afternoon you can come hang out with me and @anthrocypher.bsky.social in a popup casual learning event ❤️
