"Yrb-lite" was a meh name. My initial intent was just to get the most basic thing out, but it's decently robust as it is and i'm having fun expanding it further. Yrb and Y-Ruby aren't available, so I renamed it to "yrby" ("yer-bee"). github.com/jpcamara/yrby

Rails is a superpower for agentic development. Ruby is one of the most token-efficient languages for LLMs, using almost 2X fewer tokens compared to Go. Expect some talks about agentic coding with Rails on Nov 10-12. Early bird tickets go out July 15 at $350 for 24 hs only.

Working on getting a fix merged for this. Needs an upstream change on Lexxy (github.com/basecamp/lexxy…). With that fix, file/image uploads are now working fine for me!

I’ve got my ticket for 2026 SF Ruby, get yours July 15th! It’s the one Ruby conf I’m making this year! Rep’ing my 2025 SF Ruby Conf shirt on a hike in NH 💪

Save the date: on July 15 you'll have 24 hours to get an early bird $350 ticket for the SF Ruby Startup Conference 🪩 : - November 10-12 at SFJAZZ - 450 most ambitious Ruby founders and engineers - ❗️ President of @ycombinator, @garrytan keynoting - networking is part of the schedule: be prepared to grab a mic and do a 60-second intro

Our friends from the Ruby community are already getting their tickets to @sfrubyconf. Public early bird sale is July 15th. We can't wait to see you all on Nov 10–12.

cooking!

@inazarova 🙇‍♂️ lmk if you need any improvements!

@inazarova Haha yes! I wasn’t even really using it, I mapped directions to one address. My computer was COOKED

@jpcamara Wait, maps?!🥵

Since upgrading to MacOS “Tahoe” a day ago, the system terminally froze twice with “system ran out of application memory” claiming that zed and chrome are taking 150Gb of memory each (what?!). It never happened on previous OS. Strong Windows Vista vibes. i’m on 32 gb M2

@inazarova Ya’ll are doing it again after all?!

psssst friend, if you sign up to luma.com/sfruby now, you might be getting access to a private first sale of the SF Ruby Conference tickets (the early birds) next week 🤐

Next up I need to refine onboarding so it's easier for others to get started quickly. You can find the gems and package here: rubygems.org/gems/yrb-lite rubygems.org/gems/yrb-lite-… npmjs.com/package/yrb-li…

Spent the last couple weeks working on a gem/package to support Yjs in Rails ActionCable/@any_cable. The result is yrb-lite: github.com/jpcamara/yrb-l… I'm pretty happy with where it is at so far! Still got work to do, but def give it a try if you're curious about realtime editing

The 32nd edition of Ruby AI News is here! This edition features a fabled introduction to US government intervention, a concrete playbook for making Ruby and Rails impossible for AI coding agents to overlook, the road to RubyLLM 2.0, and much more🔻

Super cool news tonight: Rails realtime now runs on the server of your choice 🔥🔥🔥 Vova’s Action Cable server adapterization PR was merged 🥳. Same Channel and Connection code, swappable runtime underneath: Falcon, Fibers, async-cable. This is the groundwork AnyCable has been proving in production for years, now landing in Rails itself. People credit Rails’ longevity to DX. I think the secret behind it is adapterization pattern: every layer hides a default behind an interface, so the framework absorbs each new wave of innovation without a rewrite. Others wire it up with extra services. In Rails you swap the implementation as you wish, keeping the code intact. Two years in the making, with @ioquatix, @matthewd and @rafaelfranca steering the reviews. Congrats @palkan_tula 🥳

@inazarova Massive congrats @palkan_tula and @ioquatix !

Every engineer should read this. The principles for building reliable software systems have been around for a long time. Max outlines them beautifully. Here's to getting that 99.99% on your status page. planetscale.com/blog/the-princ…

The hardest part of being a developer isn't the code, it's learning that the entire internet is put together with peanut butter and goblins.

Unbelievable validation for Samuel’s vision

@brandur Finally!

Took `REPACK (CONCURRENTLY)` (which, with luck will land in Postgres 19) for a test drive over the weekend. This feature is so cool — the benefits of a `VACUUM FULL`, but without the exclusive table lock. Uses replication/logical decoding under the hood. riverqueue.com/blog/repack-co…
