I need experienced Ruby devs to help me build some small pieces to Rubian. Will and I decided what will be closed source and open source. About 98% of Kestówv and rubian will be open source. I will have the official Repo up shortly.

I dont know if the subtitles will translate it into Japanese, but my first podcast appearance landed today.
I didnt get to talk about it too much, but the operating system i built uses @yukihiro_matz original Ruby interpreter. The kernel uses Java interpreter (Jruby).
If it does translate the subtitles into Japanese, please watch it when you can. My favorite programming language comes from Japan, and I hold Matz (Matzumoto Yukihiro) in the highest regards. I hope one day I can sit down with him and learn from him personally as well as Charles Nutter (jruby) I hope i can get to do the same with Mr. Shibata too.
Today I've been working hard to make it hardware agnostic, native to our modern hardware as a host Kernel and OS.

This conference is about celebrating YOU. We mean it. 💙
So after chatting with a bunch of you, we made three changes to the event:
00:31 We changed the name back to San Francisco Ruby Conference. You were right! This conference has always been about celebrating startups, and we're not giving that up, but we still want big companies to feel welcome.
02:28 We updated our keynote speakers because Garry Tan can't make it anymore. We're honestly bummed about this news, but we've got an incredible lineup. Keynoting: Ryan Sherlock (Fin), Rosa Gutiérrez (Solid Queue), Chris Oliver (GoRails), and Irina Nazarova (Evil Martians).
04:07 Day passes are now for sale ($350/each). Day 1 will be AI-heavy and day 2 will be AI-light. Come celebrate with us on the one that excites you the most.
Most of these changes came from your comments, so message us if you have suggestions or concerns: [email protected]. 💌
We can't wait to see you there. Let's work together to bring programmers' delight into the future!

📣 Chat, help me find Ruby contacts at @limebike, the SF-based scooter company. They are in SF, on Rails and IPO’ed this year, and we want them at @sfrubyconf !

We're still looking for sponsors for @sfrubyconf to celebrate great Ruby success stories together.
The amazing team from @chatwootapp joined the event. Your company should come too!
Get in touch to sponsor: sfruby.com/sponsor-2026/
Please welcome Chatwoot (W21), an Emerald SF Ruby sponsor.
@chatwootapp is the modern, open source, self-hosted AI customer support platform. It's CEO, Pranav Raj S (@pranavrajs) shared that Ruby has been a big part of Chatwoot from the beginning.
We look forward to celebrating this Ruby story at our conference in November!

We made the tough decision to raise prices on Hatchbox.io.
Ironically, lower pricing makes products less accessible in the long run because we have fewer resources to reinvest into making it better. View article

I recently had a nice chat with @eSquareDesign about the past, present and future of JRuby... including some myth debunking that might help Ruby folks look past the "J" to the amazing tech underneath. Check out the video here:

The more code AI writes, the more readable that code needs to be.
I sat down with @eSquareDesign on Technology for Humans to discuss why Ruby and Rails are built for the AI era, how AI demos fail in production, and what’s next for RubyLLM 2.0.

RubyGems and Bundler 4.0.18 are out. bundle lock and bundle cache now accept a --cooldown flag, and the release also carries a long list of bug fixes.

Using AI to convert TypeScript into JavaScript is a great idea. We did it by hand for Turbo, but didn't get around to finish the job with Stimulus. Great idea, Notch! world.hey.com/dhh/turbo-8-is…

What does it actually take to put on a Rails conference for the first time?
This week on The Ruby on Rails Podcast, Travis Dockter joins us to talk about planning Blastoff Rails, learning in public, and why the first version should probably be simpler than your dream version.

Friends, I know a high-level Rails guy (20+ YOE, well-known Ruby community member) looking for his next role. If anyone is interested in a conversation, let me know and I can make an intro!

Real world savings from a real person. The proof is in the proverbial pudding!
Just finished moving my other product, Preceden, off Heroku and onto @hatchboxio.
The great thing about Hatchbox is that because I already had a cluster set up for Emergent Mind, I was able to just move Preceden into it, so both apps now share the same DigitalOcean infrastructure.
As far as my monthly costs, previously on Heroku I was paying:
- $50 for Postgres
- $34.95 for SendGrid 100K
- $40 for Memcachier
- $103.65 for dynos ($50 for a Standard-2X web dyno + $50 for a Standard-2X worker dyno + $3.65 for scheduler-initiated dynos)
= $227/month
New monthly costs:
- $19.95 for Sendgrid 50K
- $8 to bump the database cluster from 80gb to 120gb to accommodate Preceden's data
- $0 additional incremental costs because it shares the same DigitalOcean infrastructure I already had set up for Emergent Mind
= $28/month
Total monthly savings: $199
Not having to deal with Heroku anymore: priceless

"AI will replace developers" is the wrong framing. It will (or has) replaced some of repetitive tasks. What's left is much more important.
Judgement. Understanding. Thinking.

On this day in 1993: Yukihiro ‘Matz’ Matsumoto starts work on Ruby, the elegant programming language that became the backbone of Rails and powers sites like GitHub, Shopify, and Twitter (early days).

I have some upcoming capacity for Rails development from the end of February. Full-time short contract, or long-term part-time contract. Things I can help with:
- performance optimization
- Rails upgrade
- getting shit done
- security related features
