I ❤️ @svelte.dev!
I'm not a web developer, but I often need to make websites... and I was always frustrated by the boilerplate & learning curve of other frameworks.
IMO, Svelte is the easiest JS framework to learn as an outsider: it's just normal HTML & CSS until you need more.

HUGE day for Deno! 🎉
- The all-new, completely rebuilt Deno Deploy is now in GA
- If that weren't enough: we're ALSO launching Deno Sandbox!
Deno Sandboxes are on-demand, isolated safe zones that run on Deno Deploy. Perfect for running any untrusted code (like from an LLM, or from end users).

Cursor has hooks as well. I made a hook that tries to detect all attempts to reveal secrets from env files as well as the system's loaded env:

There's also a test script with 232 tests.

I have moved all my personal domains from Namecheap (US) to Hostinger (EU) now. It took a few hours but now I have Terraform scripts for all DNS records, so moving again should be much faster.
Next step is to move my apps to a Hetzner server I rented today. But that’s for next weekend.

I'm currently transferring a bunch of my domains from Namecheap to a European alternative but it turns out Namecheap is actually ... really cheap! INWX, for example, adds 5€ per domain for WHOIS privacy protection which is free on Namecheap. Also, `.io` domains are ~20-30€ on NC but 80€+ on INWX!

Which Europe-based Domain Registrar do you have good experiences with?
I'm looking into European alternatives to all the US-based services I'm using. Already signed up for the @proton.me business suite to replace Dropbox and 1Password. Will also move my Fastmail email there.
