This post from @honeybadger.io is about runtime types, it just doesn’t know it! It does a good job of demonstrating the simplicity and power of Ruby’s === interface, and a runtime type is simply “an object that responds to ===.” www.honeybadger.io/blog/level-...

If you haven’t yet come across the Ruby Next project from @palkan.bsky.social and Evil Martians, do yourself a favor and check it out. Especially the require-hooks gem (github.com/ruby-next/r...), which allows you to define custom “around” callbacks for when a source file is required.

If the only or primary reason you like types in your source code is to have a richer, fancier text editing experience with more dropdowns that have more items in them, you are cosplaying being a developer.

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...

I recorded a quick demo of my latest project, Empirical, a pre-processor for Ruby that builds on Literal’s runtime type system. youtu.be/G9rxcepewas

I’m preparing a talk, and I’d love to get a clearer picture of the wider community’s conception of what a “type” is. What definition would you give? What is the primary purpose of defining and using types? What constitutes a “type system”? I want to hear from you.

This a great encapsulation of how Joel and I pursue the most beautiful, ergonomic, productive DX we can imagine for the problems we tackle. In this case, we finally cracked the nut on adding typing to method signatures in a way that feels like native Ruby.

Joel and I have recently focused on our runtime typing approach for Ruby. Last week, we finally cracked the nut on adding types to method signatures in a way that feels beautiful and native to Ruby. Joel walks thru our thought process and aesthetics: joel.drapper.me/p/ruby-type...

2 kinds of 🐞: Bug of Omission: The system refuses to proceed. It raises, crashes, or otherwise stops doing anything. Bug of Commission: The system does the wrong thing. It silently deletes records, returns incorrect results, or processes invalid inputs.

There is mich wisdom in this post: alfy.blog/2025/10/04/... The web platform is such a marvel; it deserves developers building *with* it and not *against* it. I, for one, am going to try and do my part sharing more on how to leverage the platform to create beautiful experiences.

Today has been a pretty amazing day… Say hello to Emma Elanor Margheim and wish her a happy birthday!

I love what @calebporzio.bsky.social is doing w/ Flux UI, and the new pillboxes component is 😍. I enjoy trying to build components without an ounce of JS anywhere to be found. Mine requires keyboard nav with TAB, but is otherwise basically identical: play.tailwindcss.com/qB07fPsFG9 #StylishHTML

Yes, it is slow and steady progress, but we are genuinely building an amazing community of people and suite of tools for Ruby web developers. You should come hang out with us at discord.gg/fEMYkKQA

Rails 8.1.beta1 ships with this PR adding min_connections to database configuration. This will benefit SQLite on Rails apps a ton, preventing write throughput saturating the connection pool and holding back reads. github.com/rails/rails...

Now open sourced! github.com/basecamp/act...

My favorite upcoming feature coming to the Rails ecosystem is ActiveRecord::Tenanted, which is an exciting new gem coming from @flavorjon.es soon. Everyone gets a database!

The future of Rails is very very bright, especially for those of us who have already seen the light of the power of SQLite on Rails

In Amsterdam just in time to drop off my bags and make it to checkin. One more train ride to go. #RailsWorld

Starting my journey to #RailsWorld well before the sun rises 🥱

I have just opened two of the most exciting PRs for Chaotic Job. Soon, you will be able to write tests and simulations for the two most common sources of bugs in background jobs: (1) retries and now (2) races github.com/fractaledmi...

I need some great RSS feeds to provide me with some quality longer form reading material. Hit me with all of your recommendations!

🌶️ take: All IO interfaces should be owned/proxied by in-app classes. So, you should have something like an S3Client class, an FFMPEGClient class, a GoogleOAuthClient class, a QueueRedisClient class, a CacheRedisClient class, etc. in your application

We're live! Watch my little studio intro and let me know how it sounds, how it looks. Still plenty to do and improve, but I've already had my first handful of calls in here and they went great.

Getting all of the sound foam up was my second battle, but some wide head nails and stronger glue eventually did the job. Doing my first calls today in the new office/studio! Camera mount and mic arm should arrive tomorrow to unlock video recording!

Getting the walls up was only half the battle. Next major squirmish was figuring out why the fans wouldn’t run consistently. After some exploring and experimenting, learned there was a timer controller that was behaving oddly. Put my amateur electrician hat on and removed it.

It isn’t done and it isn’t perfect, but it is mine and it does work.

Here it is with the tape off and the glue set. Next up base boards (as seen on the ground) and interior.

Great afternoon of progress! The wood acoustic panels are now up on the exterior. Glue on the corner is setting. Doing a bit of door framing then base board and sound foam on the interior. Onward and upward!

Insulated! Tomorrow we put the exterior acoustic wood panels up. Then interior finishing touches. It is coming together!!

Fans and light installed!

Door is installed! Wiring up the inflow and outflow fans now, then insulation and paneling. Final finishing touches at the end. Slow and steady

Half at thru day two and getting the inner dry wall hung. A bit of wiring, insulation, then the outer panels will finish the walls. Also gotta frame the door. Great progress tho!

Day one: frame is up. It is a small little studio, but it will be mine. Made with my (and my Dad’s) own hands. Onto day two!

This corner is now cleared out and we begin framing the outer walls tomorrow. What was a little work corner yesterday will be a sound insulated tiny studio later this week

As @aaronfrancis.com says, you can just build things. The “build a small studio in the corner of the apartment” project begins now.

We should all probably be using double-dashed idents for our HTML `id`s. Once the advanced `attr()` function is baseline across browsers, this will allow us to dynamically use our `id`s as custom idents in CSS.

Simple fact: HTML is the best component framework out there. It is composable, universal, and grows more featureful by the quarter.

@briancasel.com I’d love some thoughts on using Agent OS with Zed Agents

This PR will add `min_connections` as a db configuration option. SQLite apps with bursts of heavy write traffic can remove the bottleneck of writes saturating the connection pool and holding back reads, since at the db level reads can always occur. github.com/rails/rails...

After various delays across various modes of transport I have finally made it to my room for #RailsConf2025. Now for a few hours of sleep 😴

At the gate to board my trans-Atlantic flight from Berlin to Philly for #RailsConf2025

I've been using a new text-only affordance for actions (links and buttons): "Verb →" means a navigation "Verb ↓" means downloading content "← Back" means navigating to previous page "Verb ↑" means opening a dialog "Verb ✓" means submit form I love it and users love it!

The weather this time of year in Philly generally changes a lot day to day so take the forecast for #RailsConf with a grain of salt. Here's my suggestions for anyone traveling from outside the east coast:

What is the best <50k midsize SUV in your opinion? And reminder, I live in Berlin, so has to be available here. Also, living in Berlin, I don’t need a car multiple times a day every day, which is why I only want to spend up to 50k. Hit me with your recs

Oh, and well-scoped pages with well-considered HTML leveraging basic HTTP actually plays _super well_ with AI coding assistants. I know everyone says that AI seems primed for React, but it is also great with core web technologies when used appropriately.

Worth adding that properly leveraging the power of HTTP and HTML will likely require "undoing" some of the development patterns you have learned from JS frameworks. Similarly for UX patterns. As a tweak on a Kent Beck classic: "Make the feature easy, then make the easy feature."

We all know that you can implement a tabs UI with standard anchor links, right? Aaannndd, this architecture allows you to add new tabs and additional tab content without one day running into a brick wall with loads of request timeouts. And the UI can look *exactly* the same.
