You: “I’m going to give Claude Code some skills.”

Scott Moss: "Great!"

You: “How do I get other people to use them?”

Scott Moss: “You can’t. They’re not going to have the tolerance that you have for going back and forth with Claude Code being wrong and having to prompt it again.”

We released stats from our annual developer survey.

Which group are you in?

1️⃣ 8% don't use AI for programming
2️⃣ 16% write code and use autocomplete or chat to help
3️⃣ 22% generate initial code with AI and then continue manually
4️⃣ 44% let AI write all the code but still review and edit what AI writes
5️⃣ 10% do everything with AI and no longer look at the code

How does a Kubernetes cluster respond when nodes fail?

The Raft consensus algorithm: one leader coordinates the cluster, and a new leader gets elected fast when needed, but only if there's a quorum (majority) of nodes in agreement.

Building a Fancy Scrollspy Using Modern CSS

Scrollspy navigation used to mean IntersectionObserver and a pile of JavaScript. With scroll-target-group, :target-current, and a little anchor positioning, a plain list of anchor links can highlight the current section all on its own. https://t.co/W0Vai5uZ7F

1. Oh shit, AI can do my job better than me
2. Software engineering is dead!
3. I can vibe code as much slop as I want!
4. Oh, things are not going well. Fable/Sol/Opus all suuuck
5. But what if I constrain the agent? Put it in a straitjacket?
6. Oh, the results are pretty good now. How do I go deeper?
7. *Orders 12 software engineering books from Amazon*
8. Software engineering is alive!
