It's been 4 years since I left Rails core, and my most impactful work has happened since I left. Here's a writeup of it all: kaspth.com/posts/i-quit...

So! Blue Ridge Ruby 2027 is happening (yay!) I’m on the conference committee (yaaaay!) Tickets will be on sale soon, and we’d love to have you there! blueridgeruby.com

Had a great time at @xoruby.com Montreal yesterday! Good presentations and conversations, and when I got home I still got to read my son a bedtime story 😄 (he was doing his best to delay things 🙈)

This year, Spinel is supporting the 2027 Gem Fellowship. Applications open on December 1, but companies can sign up to sponsor Fellows today. Learn more and join us: spinel.coop/blog/help-us...

Welp... Got laid off from Podia today. Kinda a lot to process for a Thursday. I'll have something more coherent to say eventually. For now, send Ruby/Rails leads. Or dog pictures.... Both are good.

our Planet of Apes is collapsing

Hot off the press from @spinel.coop: you SHOULD be checking the LoC of your gems

I can't make it to helsinkiruby.fi/tinyruby/ next week, anybody want the ticket?

say hello to peak 🏔️, the app running gem.coop github.com/gem-coop/peak

Source control doesn't need to be scary! (Find out why at our jj workshop) spinel.coop/blog/source-...

@adrianthedev.com I think you should recommend that people group Avo dependabot updates, we just put this in: ```yaml groups: avo: patterns: - "avo*" ``` and our open Avo update PRs went from 10 to 1.

it's too late. it's too late, i've already depicted you as the empty-eyed fraudulent theranos ceo struggling to emote genuinely and me as the bemused and skeptical nathan fielder

New post on my blog about switching password managers in 2026! It covers: - why your iPhone or iPad, and not your Mac, might be the place to start your switch - the recent controversy in password management and some thoughts on values - and more! rmondello.com/2026/09/07/s...

Come join us at @sfruby.com this November! Last year’s edition was awesome, and I’m sure this year is going to be even better! ❤️ clouds.sfruby.com/e/2026-bits/...

Well, its as ready as it will ever be. Still a lot of stuff I want to do, examples I want to make, but I think its time to share it. Over the past few months I've been working on Downflow. A library for adding small amounts of reactivity to your DOM. konnorrogers.github.io/downflow/

David Rodríguez wrote up his recent experience on using both Prosopite and Bullet to help fix N+1s while also removing unused eager loads 🛠️

If you’re already using mise and would like to try rv, you can install it by following this guide: www.rubyforum.org/t/install-rv...

Merged JRuby install support into rv.dev by @spinel.coop tonight!! My first open-source rust code! big day for me over here lol.

tbh I've been kinda fucked up since yesterday, having seen the video of DHH going around. it's been genuinely disturbing to see a person I once knew so far gone and clearly mentally ill.

it's been great working with tierney, highly recommend them

a reminder that I’m still looking for full-time developer relations roles and I’m open to full-time software engineering roles

Spinel Dev Log for July 2026 spinel.coop/blog/spinel-...

I really enjoyed chatting with Federico, about my time on Rails core, and the craft that's still useful and dear to me. www.youtube.com/watch?v=xEBW...

My "Getting Started" guide for Rack just got merged to the official docs! :D Rack underpins every #Ruby web framework and app server, yet I don't think it's always well understood. Give it a read!

The blog post as promised ...

Pattinson can only do those voices because he was put in The Contraption

It's been a while since I've done a people looking for work thread. If you're looking for work, put what you do and what you're looking for (full time, freelance etc) as a reply. Companies: get hiring people!

In this guide, you’ll learn how to use rv (https://rv.dev/), a very fast version and package manager for Ruby to get started in minutes instead of hours: https://www.rubyforum.org/t/install-any-ruby-version-in-seconds-using-rv

You might be worried about the future prospects Ruby, and, you want to be sure that learning Ruby is worth the effort. I’ve compiled a list of reasons to learn Ruby from people using it every day so you can pick the one that resonates with you: https://www.rubyforum.org/t/compelling-reasons-to-le

RE: https://ruby.social/@spinel/116965667079861714 RV now supports private gem servers like Sidekiq’s. Hurrah! 🎉

rv 0.6.0 is out! spinel.coop/blog/rv-0.6....

Factory Frustrations: Optimized for Isolation spinel.coop/blog/factory...

I just released Insta, a new snapshot testing library for Ruby, live at RubyConf in Las Vegas! Extracted from Herb's test suite and inspired by @mitsuhiko.at's fantastic insta library for Rust. `gem "insta"`

Meet Spinel 👋 spinel.coop/blog/meet-sp...

we're working on more posts for the Spinel blog in the spirit of open source, if you'd like to critique one I've written before it goes out, you can do so here github.com/spinel-coop/...

I've been loving working at @spinel.coop for the past year. It's exactly what I've been looking for, for a long time: people who are obsessive about Open Source, who also want to be roaming Staff Engineers that help multiple companies. You can meet us here spinel.coop/blog/meet-sp...

a nice rv.dev win: I just dug up an old app that was on ruby 3.4.5, a ruby version I'd deleted. `rv ci` installed ruby and all gems in < 10 seconds.

`sentiero` browser session tracking/recording Ruby gem is finally up. Took a while; added (basic) error tracking & analytics features too Its a Rack app so can be used standalone, or mount as Rails engine. It tries hard to have privacy respecting defaults & opt-outs. github.com/stevegeek/se...

I've been enjoying jj immensely so I wanted to write up everything you need to know about my experience kaspth.com/posts/an-in-...

#Ruby folks, I'm looking for my next client ... I'm available 20h/week and usually work with long-term clients (6 months or more) to make the most impact.

ruby oldheads scoff at rv being in rust, but it's because it can enable a new era of rubyists to join us by vastly lowering the barrier to entry. precompiled downloads with dependencies are table stakes in 2026
