Rails on SQLite: exciting new ways to cause outages
This post was originally given as a talk for Friendly.rb. The slides are also available.
Between Litestack and the Rails 8 trifecta of Solid Cable, Solid Cache, and Solid Queue, it’s easier than ever to spin up a Rails app that doesn’t need a database service, or a redis service, or a file storage service. It’s great to simplify things, but even after 20 years of deploying Rails apps I was still caught out by some of the ways things are different.
Today, we’re launching the Model Context Protocol (MCP) Registry—an open catalog and API for publicly available MCP servers to improve discoverability and implementation. By standardizing how servers are distributed and discovered, we’re expanding their reach while making it easier for clients to get connected.
The MCP Registry is now available in preview. To get started:
Add your server by following our guide on Adding Servers to the MCP Registry (for server maintainers)
Access server data by following our guide on Accessing MCP Registry Data (for client maintainers)
Single source of truth for MCP servers
In March 2025, we shared that we wanted to build a central registry for the MCP ecosystem. Today we are announcing that we’ve launched https://registry.modelcontextprotocol.io as the official MCP Registry. As part of the MCP project, the MCP Registry, as well as a parent OpenAPI specification, are open source—allowing everyone to build a compatible sub-registry.

This migration involved a complex codebase with hundreds of screens and native modules, extensive custom components, and deep integration with first-party libraries like FlashList.
Finally, safe array methods in JavaScript - Matt Smith
Learn how to safely sort, reverse, and splice arrays in JavaScript using ES2023 methods toSorted(), toReversed(), and toSpliced(). Perfect for React and modern JS development.
Templates, CSS imports and other non-standard enhancements to JavaScript are crucial for many projects. In spite of that each of our tools requires their own plugin to make this work. What if we had a shared processing pipeline?
