Four months of Ruby Central moving Ruby backward From the moment RubyGems was first created in 2004, Ruby Central provided governance without claiming ownership, to support the Ruby community. Providing governance meant creating processes to provide...

Happy to see Andre finally speaking publicly about the hostile Ruby Central takeover last year. RC is no longer a trustworthy steward for the Ruby community. I don't see how we repair this rift without Shan stepping down, she has been awful as ED.

Phlex::TUI is not just a component system. It’s a layout engine, a rendering engine and a reactive component framework all in one. And it’s 100% Ruby with no dependencies.

This is a huge release for TruffleRuby. It’s our first under our new org.

If you’ve been hesitant about contributing because of the CLA, please note that we no longer have one. We can also release more frequently so please report bugs or open PRs.

Honeybadger team collage from 2025 conferences featuring team selfies, booth setup with "Application Monitoring for your whole stack" banner, San Francisco Ruby Conference at Gateway Pavilion, group dinner, wooden skate decks with Honeybadger artwork, and "Future Proof Software" presentation backdrop.

In 2025, we hit the conference circuitβ€”RailsConf, Laracon, ElixirConf, to name a few.

We shipped smart "Just Enough APMβ„’" dashboards, Insights Alarms, an EU data region, plus integrations with @incident.io, @rootly.com, and more.

Thanks for a great year. See you in 2026! 🧑

What’s really amazing about vibe-coding is how people are replacing programming languages which are strictly deterministic with human speech which is highly ambiguous and expect programming to be faster and better.
