Evil Martians' black-box checks are thoughtful benchmark design: they grade what an unfamiliar Rails app does without assuming how its code is structured.

Agents on Rails is the Rails Foundation's LLM benchmark. We designed its eval tasks and the tooling to run at scale. Read how we wrote black-box checks for apps with code we'd never seen, keeping trials fair and results reliable. Bonus: the same evals against Rust. evilmartians.com/chronicles/t...

@sfruby.com also made the list of the top ten conferences Rubyists plan to attend this year. How exciting!

Our engineers are encouraged to write for blog, which then powers most of our marketing. Hundreds of thousands of people read it every year. We’re thrilled it was rated the top blog in @planetargon.com's 2026 Ruby on Rails Community Survey. Thanks to everyone who reads us and Travis for running it!

At first, we were going to call the game “Populate the Pier.” Now it’s just “The Pier,” but it’s for sure getting populated. We can’t wait to see you all on Nov 10. (Although we do need time to pass slowly, because there are still so so many things left to do.) 😅

We'll build your idea and open source it for free. 👀 All @sfruby.com attendees get access to our pre-conference game, where they can complete quests to earn coins and redeem them for real prizes. Get a ticket, play the game, and get the chance to work with us for free: luma.com/sfrubyconf2026

This cat won't give you allergies. 🐈 Go to The Pier, catch the cat, keep it as your pet for a few minutes, and earn one heart. That’s, of course, if the cat chooses you back! Remember that the coins and hearts you collect in the game are redeemable for real prizes at the conference.

This week's spotlight shines on @mattsolt.bsky.social. 🔦 He's bright, community-driven, and approachable. As an AI enthusiast, Matt writes RubyAI every week and is building Poetry UI. We're so glad to have him attend the conference for a second time and can't wait for you to meet him.

Chris Fung (@aergonaut.com) found Ruby by accident and immediately knew he didn't want to write PHP anymore. Then, he joined the community and loved how fun people were. 💙 If you want to meet a kind, smart, and fun person at the conference, find Chris in the audience and start a conversation.

Talk to me about any of my other myriad niche hobbies, like fountain pens, mech keyboards, or homelabbing! Hope to see you at the conference!

In a world where everyone can build apps with AI, our job is to build skills, harnesses, and tooling that help them make better apps. But for new builders to choose Ruby/Rails, we need to talk to each other and understand what's missing in the ecosystem. That's the whole idea behind @sfruby.com.

Emerald sponsor announcement: Chime, one of the brightest Ruby success stories. This fintech focuses on making its core banking services helpful, easy, and free! Chime went public about a year ago, and made us all in the Ruby community really proud. Come say hi to the team at the conference.

Fin is a Ruby sponsor for SF Ruby Conference 2026 and a Ruby success story worth celebrating. Salesforce agreed to acquire it for about $3.6 billion! You can chat with the Fin team about this at the conference. Plus, Ryan Sherlock, its senior director of engineering, will do a keynote on day one.

We have no words to describe how exciting it was to see our team's faces on the Rails World screen this morning. Thanks to @amandabrooke.bsky.social for the trust and our team for the work they've done for The Rails Foundation. You can check the Agents on Rails report here: rubyonrails.org/ai

Ahhh, thanks for the kind words! Was fun to chat! See y'all at SF Ruby Conf in November!!

The people in this community are warm, open, smart, and fun. 🤩 @milesgeorgi.bsky.social has all of those qualities. If you've been to a Ruby meetup in the country, you've likely seen him. He's attending our conference this year, and we had a little chat with him so you can get to know him too.

If you cross paths with Miles at SFJAZZ this Nov 10-12, say hi. Talk to him about domain complexity, Foobara, Ractors, or software engineering in general. He'll also enjoy it if you challenge him to a chess game. ♟️ Only 9 days left to get tickets at regular price: luma.com/sfrubyconf20...
