I sent 200 pull requests using Claude Code and wrote about the experience. It's pretty wild!
For dplyr releases, we send a PR any time we break an #rstats package. This release advances a lot of deprecated functions, triggering issues in many old packages!

I was at Texas A&M in the late 90s and EVERY TIME I see a news item about it now, I know I’m about to be embarrassed 🙈

Good morning. I'd like to invite anyone who is interested to make a small gesture of kindness today. It's up to you to decide what that can be. The key is for you to act on the idea. With so much out of our control, we can choose how to be with each other today and every day.

what you clearly see, CLEARLY, is a driver who is spooked by the agents grabbing her door, takes steps to drive away, and is immediately shot as moves her vehicle *away* from the agents.

I am struggling with what might be a generational experience. The gulf war was pretty politically formative for me. It’s not history so much as memory this time.
It is destabilizing to see almost the exact same gameplan but this time without the guardrails that at the time I took for granted.

Thinking about running local models with coding agents like Positron Assistant? 💻
A new evaluation by @simonpcouch.com and @sara-altman.bsky.social suggests we aren't there yet. Between hardware hurdles and performance gaps, hosted models are still the best bet for now.

LLMs that can run on your laptop are not yet capable enough to drive coding agents.

I get the appeal of local LLMs—free, private, no big tech. That said, they're not yet ready to power coding agents like Positron Assistant or Databot.
