They need instantly available containers for short bursts. People in the comments are telling them to use k8s next time because it "auto scales". K8s!! They're spending $12 per month, less than a netflix subscription. Many such cases:

Many such cases:

We had to choose: Serverless (Lambda) or Containers (EKS) for a new image processing service. Team was split: - EKS meant standardized tooling with the rest of our stack. - Lambda meant zero server management. The workload: Spiky. 10 requests/hour, then 10,000 during a peak…

Introducing Cursor 2.0. Our first coding model and the best way to code with agents.


Dave Kerr รีโพสต์แล้ว

both cursor and windsurf released models today heavily optimized for speed this is very different than the direction people have been pushing where they kick stuff off to codex for 45min but it's fast feedback loops are always what end up mattering

I think the craziest experience I had during this interview cycle was a coding challenge where they were like, "You're allowed to use AI tools like Claude Code during the coding interview." I said, "Really? Well, if y'all insist..." For that interview, the approach I took was…

it's been long demonstrated across every domain that fast feedback loops are the #1 thing to optimize for i think the big llm labs are getting too obsessed with long running async agents sonnet making all these intermediary markdown files has made it unusable

From a dev at Big Tech: “3 devs across 3 teams are stuck for a month on a build problem that’s caused by connections resetting between two gateways and a messaging queue. I cannot solve it because I’m blocked access to the other 2 teams’ systems. I cannot see AI solving this.”

We're launching Claude Agent Skills, a filesystem-based approach to extending Claude's capabilities. Progressive disclosure means agents load only relevant context. Bundle instructions, scripts, and resources in a folder. Claude discovers and executes what it needs.

It’s now 27 years since I was made redundant and given a few grand. I decided that if I was careful, I could live off the money for 6 months trying to become a comedian before I had to get another job. I was 37. Worth a punt.

You can now chat with apps in ChatGPT.

Claude is now available in Slack. Chat with Claude through DMs, tag @.Claude in threads, or use the AI assistant panel—with access to web search, document analysis, and your connected tools.

I think it's fair to say that PlanetScale is known for having a high bar for hiring. What you probably don't know is that we don't do coding interviews.

If AI ends in the mother of all busts, it won't be because people were enthralled by short-form videos. It will be because people were enthralled by the "good stuff," the olympic-level math, etc. that convinced them there was a path to productive intelligence.

Cursor can now control your browser. Agent can take screenshots, improve UI, and debug client issues. Try our early preview with Sonnet 4.5.

We asked every version of Claude to make a clone of Claude(dot)ai, including today’s Sonnet 4.5… see what happened in the video

Introducing Claude Sonnet 4.5—the best coding model in the world. It's the strongest model for building complex agents. It's the best model at using computers. And it shows substantial gains on tests of reasoning and math.

When Claude Code fetches Bun’s docs, Bun’s docs now send markdown instead of HTML by default This shrinks token usage for our docs by about 10x
