The Ruby Passport, coming to an event near you 😎

If I were to recommend just five articles from last week, these would be my choices. #FiveRubyLinks #Ruby #Rails #Reading

Preparing first workshop for an in-house training session for a company about Reliable Test Case Generation with AI, part of #GoodEnoughTesting This will be about the Test Strategy, a document that will be useful for both agentic AIs and individual contributors

#Ruby namespace will be renamed to `Ruby::Box` An MR about this was merged to the Ruby master a couple of days ago github.com/ruby/ruby/p... by @tagomoris.bsky.social

When you have multiple stimulus actions on an element for different controllers do you order by the trigger or by the controller? I initially ordered by trigger but my project partner called it out in PR review to order by controller. I think they both make sense but I'm curious what others do

If you're in Europe and have FOMO because you can't attend the amazing @sfruby.bsky.social, there's another conference happening over here in Helsinki 🇫🇮at the same time 😊 helsinkiruby.fi/tinyruby/ from @helsinkiruby.fi - the line-up is great and Mochi will be attending 🐶🐾❤️It's going to be very nice!

Who else is curious about @palkan_tula’s “Rails X” keynote at the end of @sfrubyconf?

low-priority tasks assume that at some point you’ll be done with the high-priority ones

It's official! The beta release of Eloquent Ruby, 2nd edition is now on sale! pragprog.com/titles/eruby...

I'm pretty certain, though I haven't had the time to develop a proper data scraper to confirm, that Ruby articles are appearing more frequently on the front page of Hacker News this year. I'm specifically referring to technical articles.

Working at @shortruby.com brings a great feeling, especially seeing some #Ruby blogs that haven't posted in years start sharing content again. I don't know their reasons, but I imagine, perhaps they now have more time or have renewed faith in the community's growth.

The Vancouver Ruby Meetup is looking for speakers either remote or in-person. Curious? Want more details? Contact the organizers for more details. vanruby.ca

This is going to be super fun! Paweł is one of the nicest, kindest people around 🩷, Mochi will be there 🐶🐾, and we'll be going from Belgium, so expect speculoos and chocolate for the cookie exchange! 🍪🍫 I'll be bringing mathematics and some German as well 🇦🇹🥰

There’s a lot of discussion about using LLMs to build applications, including generating test cases. It’s interesting to read people’s experiences and see how LLMs are affecting software development. Opinions on the usefulness of LLMs range from very positive to negative

Ruby 4.0 is officially official! #RubyWorld

When I work on a project that uses RSpec, I prefer not to use let!. Instead, I call the let variable inside the before block.

When using LLMs in software development, generate either tests or code, not both, to avoid risks. For complex problems or business logic, stick to one choice.

If I were to recommend five articles published last week to read, here is what I would recommend

TIL StimulusJS supports keyboard event filters out of the box. I was so close to writing a bunch of custom JS before thinking to myself "nah, there's got to be a better way" . Of course, there was. #ruby

Let me tell you this: @Rails + @avo_hq + @claudeai + AgentOS = super power for testing ideas I also added a Claude Code skill about Rails Test Designer to take care of some tests but so far it made a nice web app.

I'm making another attempt to get a `deep_freeze` method added to Ruby. Core folks have rejected proposals for years, until Ractor came along and we got basically the same feature in `make_shareable`. But deep freezing should be its own feature. bugs.ruby-lang.org/issues/21665

Short Ruby Newsletter @shortruby.com edition 155 was published today! This edition is sponsored by undercover-ci.com, the Ruby coverage toolkit ready for the vibe coding era.

Week 44 - Debugging Bridge Components, Rethinking CSS with Roux, and more!

Make sure you read yesterday announcement from @Rails about the end of support for Rails 7.0 and Rails 7.1 rubyonrails.org/2025/10/29/...

Here's a fun bit of Ruby metaprogramming: get the name of the method that called the current method. `caller_locations(1, 1).first.label.split(" ").last` docs.ruby-lang.org/en/master/Ke... 🧵 1/3

Announcing RactorPool: github.com/joshuay03/ra... Extracted from a project I'm building with Ractors. Currently requires Ruby 3.5 (3.5.0.dev). Goal is to have it stable for Ruby 4.0, when Ractors will be less experimental 🤞🏽

Here are five links from last week in the #Ruby world that I believe are must-reads. Subscribe to @shortrubynews to receive these recommendations in your inbox every week.

Only three spots remaining for this Friday's workshop about Reliable Test Case Generation with AI goodenoughtesting.com/learn/relia...

Putting the finishing touches on the beta release of 2nd edition of Eloquent Ruby, which should be available sometime in the next couple of weeks. This has been a long, long journey but the finish line is at least out there on the horizon. I mean, who writes a book with 746 separate code examples?

Our recordings are now live! You can see them both aggregated by Ruby Events and directly on ConFreaks' channel: www.rubyevents.org/events/rocky... www.youtube.com/@Confreaks/v... (no playlist yet for the latter, but they are the most recent right now!)

Will be releasing an update for poshtui.com TUI client today or tomorrow.

🚨 New Episode Alert!🚨 A few days ago I was joined by Dave and Steven to discuss misunderstood concepts in tech. We strayed away from that so as a bonus you also get: - A comparison of the state of the car industry vs the tech industry 60 years in. 👇

I was recently reminded that not everyone fully understand what the frozen string literal magic comment is about. So I figured it was the occasion for another deep dive. byroot.github.io/ruby/perform...

Just shipped a guide on adding syntax highlighting to Rails apps. Covers multiple approaches for blogs, CMS, docs, and any app with markdown content. Plus some UX tricks that actually matter for developers reading code. Read the full article on: avohq.io/blog/code-h...

I'm excited to share that I became a Ruby committer today! A 10 year goal since RubyKaigi 2015. Huge thanks to @bernsteinbear.com for the JIT mentorship and nomination, @k0kubun.com for years of guidance, and everyone who supported me along the way. Looking forward to improving Ruby and its DX!

Last week, several podcast episodes about #Ruby were published. Here's what we found and added to @shortruby.com

LLMs can write a lot of tests. But let’s not confuse a lot of tests with good tests. For instance, a single well designed test could prevent a major failure that fifty auto-generated ones might miss (of course there the proportion is relative).

Only five spots are available for the Good Enough Testing: Reliable Test Case generation for Ruby developers. This will be an interactive workshop where we will work with code samples from two open-source Ruby on Rails projects and learn how to generate test cases using LLMs.

Week 43 - Swift SDK for Android, Liquid Glass Tab Bar, and more! https://www.hotwireweekly.com/archive/week-43-swift-sdk-for-android-liquid-glass-tab-bar

Add comments to your database, not just for people, but for LLMs too! Explain why a column exists or how you chose its name? Good comments turn your schema into a mini-README, great for onboarding & AI tools. In Rails migrations, you can add comments your tables and columns:

Hello, Rubyists! If you love coding but sometimes find writing tests to be a chore, I have something for you. My upcoming workshop focuses on using AI to help you generate reliable test cases.

When developing a strategy to generate tests using LLMs, it's crucial to ensure the tests run quickly. This accelerates the think-test-change cycle, enabling faster implementation of modifications.

Joel and I have made fantastic progress on our Ruby enhancements gem that brings rich runtime type assertions into your Ruby projects and Rails apps. Joel recorded a short demo of how to add type constraints to method definitions: www.youtube.com/watch?v=G9r...

After a year hiatus, my series on all things Ruby concurrency is back! This post digs into the interrupt mechanism in Ruby threads. These interrupts revolve around bit masks, so it's got some Ruby bit work as well! Expect more regular updates from now on 💃💃💃 jpcamara.com/2025/10/22/b...

If your are unsure about adding a new column to a table or creating a new model, always create a model. Your code base will thank you. Let's have a look to the User model.
