A boat marina under a partially cloudy blue sky. The colors are reflected in the deep blue of the water.
A view of Shilshole marina in Seattle. Two docks on either side of the picture are full of sailboats. The blue water is calm and reflective. Olympic mountains rise in the distance.
Picture of Shilshole marina in Seattle with a boat tied up to the dock that is actually resting on its hill. Exposed dirt and rock are just a few feet to the right of the boat.
An upward facing shot of stacked crab pots in the back of a flatbed. The pots are stacked 6 high and there are 7 rows. A blue sky is in the background.

💡 Bonus idea (this is actually interesting) You could build: “rrd-lite” backed by DuckDB fixed retention policies automatic rollups
A status update from status.claude.com indicating that "Users with scheduled tasks in Claude Cowork or Claude Code who are in a timezone that observed daylight saving time last night were affected by an infinite loop."
A high-quality marketing photo of a plush toy inspired by the Claude Code avatar, sitting on a wooden desk next to a laptop displaying code. The "stuffy" is a vibrant coral-red color with a round, fuzzy body covered in numerous soft, conical fabric spikes that give it a playful, sea-urchin-like appearance. It has two simple, glossy black eyes and a small, friendly smile. The plush is holding a small, rolled-up paper scroll tied with a red ribbon that reads "AI CODING COMPANION." The background is a brightly lit, modern home office with a blurred bookshelf and a small potted succulent. In the bottom right corner, the Anthropic logo is visible.
A screenshot of the text: Ha, yeah. The "I just want to run Home Assistant" starter pack: - 5 control plane pods (the price of admission) - 4 Fleet pods (so you can GitOps the 1 app) - 1 local-path-provisioner (so HA can save files) - 1 Tailscale operator + 1 proxy pod (so you can reach it) - 1 ExternalDNS pod (so it has a nice name) - 1 Home Assistant pod (the actual thing you wanted) 13 pods of infrastructure, 1 pod of value. That's the k8s tax. The good news is the overhead is basically flat — adding the next 10 apps costs ~1 pod each (plus a TS proxy if you expose them). The bad news is you could've done this with docker run and a Tailscale sidecar in about 5 minutes. But hey, now you have GitOps.

A pivotal moment from the Seahawks vs. Rams NFC Championship game where a Rams punt returner muffed the catch and a Seahawk is seen running past him to recover the ball as the Seahawks go on to win the game. The Ram player is bent over backwards with legs sprawling in the air as he tries to reach hopelessly for the ball that is now behind him.

A tweet from an alleged Anthropic engineer stating: I believe this new model in Claude Code is a glimpse of the future we're hurtling towards, maybe as soon as the first half of next year: software engineering is done. Soon, we won't bother to check generated code, for the same reasons we don't check compiler output.
