Reading up on Bundler

A maintainer's analysis of RubyKaigi 2026 survey data reveals that Ruby 4.0 adoption matches 3.4 within six months, Claude Code dominates at 80% usage, and VS Code/Cursor lead editors while mise/asdf challenge rbenv.

Vite 8.1 introduces experimental bundled dev mode for faster startup in large apps, chunk import maps, Wasm ESM support, and moves toward Lightning CSS by default.

rv is a fast Ruby manager that precompiles Rubies, manages gems, and aims to match uv's speed, with recent progress on clean-install, tool management, and multi-platform support.

A survey finds that while many package managers and update tools have adopted dependency cooldowns to prevent supply chain attacks, implementations vary wildly in naming, scope, and timestamp handling, and major ecosystems like Go, Maven, and Gradle still lack support.

Aaron Patterson argues Bundler can match uv's speed through design changes like parallel installation and a global cache, not just a Rust rewrite.

Go's module proxy and transparency log can be repurposed to fetch and verify Ruby gems with better integrity guarantees than RubyGems itself.

Ruby's redesigned homepage highlights the language's fun, readable syntax, rich gem ecosystem, and supportive community through testimonials from Matz, DHH, and others.
