AIの可能性を最大限に引き出し、AI活用に伴うリスク管理とイノベーションを両立するための基本的な考え方をご紹介します。

By: Richard Schneeman This document attempts to give closure to the Ruby community about the events that led to the incident, September 10-18, 2025, which I’ve named “RubyGems Fracture.” Preamble I joined Ruby Central’s Open Source Committee on October 22nd, 2025, after the GitHub access changes. I was

The RSpec suite took 25 minutes on a MacBook Pro M3 Pro. The migrated Minitest suite runs the same models in 14 seconds. I built a 6-gate multi-agent pipeline in Claude Code to migrate 9,000+ tests, using specialized agents with strict I/O contracts and fixtures instead of factories.

Terraform-style, declarative schema migration CLI for Postgres. Agent friendly. - pgplex/pgschema

How good is the random_page_cost default, and should you lower it on modern flash storage?

pg_textsearch 1.0 brings native BM25 search to Postgres. No Elasticsearch sidecar needed. Learn how it works and see benchmarks vs. ParadeDB at 138M documents.

Since the dawn of time, React maintainers have claimed that React’s virtual DOM is fast enough for complex interactions as long as you memoized your components. Then someone tried to put an entire Harry Potter novel in React ProseMirror, and I had to find out if they were right.

TanStack Router now uses a granular signal graph as its reactive core. State is derived from that graph, which narrows change propagation and makes client-side navigation faster in our benchmarks.

This is an experimental, work-in-progress port of React Compiler to Rust. Key points: Work-in-progress - we are sharing early, prior to testing internally at Meta, to get feedback from partners in...

A little language inspired by Rust that compiles to Go - ivov/lisette

Little language inspired by Rust that compiles to Go.

Your laptop has ripgrep, installed via cargo install. ruff is there too, via uv tool install. golangci-lint came from go install. bash-language-server was npm i -g. Neovim was a tarball download. Kitty was a curl script. Six months later you get a new machine, or you just want to upgrade or reinstall. What do you even have installed? How did you install each one? Which version? Good luck. This is a small system that answers those questions — a single Makefile that declares every tool you care about, grouped by purpose, with one command to install anything.

How we took our warm start service from 2,099 req/s on Node + SQLite to 10,700 req/s on a compiled Bun binary, and found a subtle memory leak that only exists in Bun's HTTP model.

We have been using Signals in production for years via several modern front-end frameworks like Solid, Vue, and others, but few of us are able to explain how they work internally. I wanted to dig into it, especially diving deep into the push-pull based algorithm, the core mechanism behind their reactivity.

What actually happens when you type a message into Claude Code? The agent loop, 50+ tools, multi-agent orchestration, and unreleased features, mapped from source.
