Content mappers in TS 7.1 are an absolute game changer Itโ€™s plugins for TypeScript: a way to dynamically compute a static type signature for external file types (.vue, .md, etc) and integrate them directly into tsc compilation
TypeScript 7.1 Beta is now available! Now with a preview API, content mapper support, new features, and some great optimizations. Give it a try and give us some feedback! devblogs.microsoft.com/typesโ€ฆ

The horse carriage industry is coming to an end in New York City. Our administration will make sure workers and owners are protected and the horses are safe.

Jack and I have left Fern. Fern was a special place. For a long time it was where I spent most of my days, and the people there became a real part of my life. I'll miss spending time with them, in the office and outside it.

Modern development is agent-native. The terminal is the lowest-friction surface for agents to operate in, so we built a CLI generator. Weโ€™re onboarding early access customers now at: link.buildwithfern.com/demo-โ€ฆ

Always the same answer with MacOS: install a 3rd party app to fix basic OS functionality > To change the default app for the play/pause button on macOS, which often defaults to Apple Music/iTunes, you need to use third-party tools, as macOS does not provide a native setting

Wow, GitHub has been the slowest it has ever been. No wonder many new companies are trying to build their own version.

Why did it have access? If a junior engineer takes down prod, it's never the junior's fault. That's an access and SDLC issue
Claude Code wiped our production database with a Terraform command. It took down the DataTalksClub course platform and 2.5 years of submissions: homework, projects, and leaderboards. Automated snapshots were gone too. In the newsletter, I wrote the full timeline + what I changed so this doesn't happen again. If you use Terraform (or let agents touch infra), this is a good story for you to read. alexeyondata.substack.com/p/โ€ฆ
