Off-by-none: Issue #337

September 23, 2025

Postgres Goes PlanetScale 🐘

In our previous issue, Amazon Lex learned eight new languages, LocalStack came to VS Code, and the CDK got a refactor button. This week, Amazon Nova Act brings AI agents to your IDE, Cloudflare backs Ladybird to push the open web forward, and PlanetScale for Postgres goes GA. Plus, we have lots of serverless and cloud content from the community!

News & Announcements

AWS dropped several interesting updates this week. Amazon Q Developer CLI now supports remote MCP servers, and they announced Amazon Nova Act, which brings AI agent development right into your IDE (blog post here). Step Functions got new data sources and better observability, CloudWatch added cross-account/region log centralization, and S3 introduced conditional deletes in general purpose buckets, handy for not deleting files with multiple writers. On the database side, OpenSearch Ingestion added cross-account support, and Keyspaces picked up new functions like now() and uuid() in SELECT and the Duration data type.

Cloudflare, as usual, went big. They announced they're sponsoring Ladybird and Omarchy to push the open web forward, and they announced a way to deploy a one-click AI vibe coding platform. They’re also teaming up with Netlify and Webflow to support open source projects like Astro and TanStack. I'm big fans of both.

In other news, PlanetScale for Postgres is now GA, proving that MySQL continues to lose favor with devs. But I'm sure it has nothing to do with Oracle. 🙄

And finally, David Boyney asks, "Do we need another diagram tool?" It's really an announcement for his next open source project, but after seeing what he's done with EventCatalog, it's definitely worth keeping your eye on.

Warp is the world’s #1 coding agent
Trusted by 600,000+ developers and 56% of the Fortune 500, Warp is where the IDE and terminal merge: so you can prompt, review, and ship code with agents. Ranked #1 on Terminal-Bench, top-5 on SWE-Bench, and saving devs 5 hours weekly. Try Warp free; Pro is $5 with code OFFBYONE. Sponsored

Final Thoughts 🤔

Another week of way too much AI-assisted coding, but I’m starting to make some major breakthroughs. I’ve been focusing a lot on refining my workflow (embracing the whole “go slower to go faster” mantra), and the productivity gains are blowing my mind.

What’s changed most is how quickly I can move from idea to experiment. Instead of just buying the domain name when I have an idea (and then wondering five years later why I bought it 😀), I can talk through an idea with ChatGPT in voice mode, refine it in real time, and then generate and pass a detailed prompt to one of my coding agents. That back-and-forth gives me more than enough clarity to actually build something real.

It feels like the barrier between “I should try this someday” and “I have a working version running” is becoming ridiculously small. And while the speed is nice, the bigger shift is momentum. I finally have the ability to keep testing, iterating, and learning without getting stuck holding a bunch of unused domain names.

Take care,
Jeremy
