There’s growing research in how LLMs actually understand our frustrations and adapt. It’s a fun journey.

All modern language models sometimes act like they have emotions. What’s behind these behaviors? Our interpretability team investigates.

Previously I’d type “git” and it would complete “GitHub.com” then I press “/“ and it offers the next segment, continue until correct. Now it does the horrible Chrome thing and typing “git” guesses some repo I don’t want

Eurgh, @jakearchibald.com; help! This is a major regression. Segment based, domain first, auto-fill is one of the main reasons I'm still on Firefox and it's being removed? Navigating GitHub is impossible without it.

Hey @wimpys.world, isn’t the reason someone hasn’t configured a neovim with common access shortcuts before because neovim runs in another application, your terminal, which uses those common access shortcuts?

Disagree. It’s not governance, it’s misaligned incentives. Orgs literally had lead boards and encouraged tokenmaxxing, contributors gave them what they asked for; incentives weren’t in place to deliver value.

You think you know @kubernetes.io ? Let’s start with the easy challenge, who can do it without the hints?

The cluster is broken. Fix the plumbing to bring the app to life (you'll know it's working when Rawkode taps his watch at you), then ship the v2 image to unlock his victory dance.

I've been rewatching The Mentalist. Such a fantastic show, even on the 8th rewatch. Highly recommend.

I've deployed a couple of challenges, #Klustered style, to @iximiuz.bsky.social's Labs. I hope you have fun trying to fix them, though there is a guide provided if toy want to learn rather than debug. Have fun out there!

Lastly, the WASM extensions are all shipped as OCI artifacts. But I’m sure you didn’t expect anything else.
