I'm back on @deadcode.website to talk about the impactful Open Source I've done since Rails core. We get into what these gems are and the philosophy behind them. shows.acast.com/dead-code/ep...

Finally, after too many years, I've pushed 1.0.0 of typed_operation gem. Blurb: a command pattern, callable, chainable, traceable, can be partially applied, curried and w. typed params. Auth to execute via action_policy if desired. rubygems.org/gems/typed_o... / beta.gem.coop/@stephen/typ...

We’re collaborating to bring the following projects discussions to the forum: action_controller-stashed_redirects active_job-performs active_record-associated_object brut cogger containable filterameter infusible oaken refinements sod taylor Please repost! www.rubyforum.org/t/ruby-users...

Is this too much indirection? Context: since Associated Objects let you write smaller objects, having Mailers with one action becomes common. And then the Mailer becomes mostly plumbing.

Here's a nice rv win. Because Ruby installs take seconds it was super easy to verify behavior across many Ruby versions. So I can just swap out the version and run my test code in irb like this: rv run --ruby 4.0 irb

I was just looking for something like this, nice post @julianrubisch.at!

some odd ones on the guestbook, but I kinda like the silly ones too lol kaspth.com/guestbook thank you to people who've signed it!

Weeknotes: Hanami Minitest, merged! Awkward body parser middleware, gone! New guides version, initialised! Hanami mailer, getting close! Upcoming site, veiled in darkness! timriley.info/posts/contin...

I chatted with @chael.codes about her upcoming @blueridgeruby.com talk, "Your First Open-Source Contribution." I had to know which was more intimidating…contributing to open source for the first time or live streaming? Full episode: www.youtube.com/watch?v=ovAb...

Zoo is hiring a Rust infra engineer! zoo.dev/jobs/4633118... Come work with us, on our Rust services!

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...

take a trip to the cool shit store! population: you.

I chatted with @thomascannon.me about his upcoming @blueridgeruby.com talk, "5 ways to invest in yourself for the long haul." I wanted to hear why you should invest in yourself even if/when you have a great job. Full episode: www.youtube.com/watch?v=V8Zp...

I've been really impressed with the kindness and support in the comments on my post on reddit. Shoutout to /r/rails! www.reddit.com/r/rails/comm...

it's nice to see @kevinjm.bsky.social being showered with recognition

I'm really excited where we're headed with gem.coop, I think there's a real chance we can make significant advances for Ruby as a whole in a way that's equitable and with aligned incentives for all. More on that soon, but here's how namespaces work with Bundler today: gem.coop/updates/6/

I think people are making a mistake trying to revive fixtures and forgetting all their inherent issues. I've worked with fixtures in production and doing what @thomascannon.me describes would be extremely difficult. Oaken makes deep refactoring like this doable.

Love to read this. Repo link for the skills @kaspth.com mentions: github.com/palkan/skills

I've also been reading through @palkan.bsky.social's & @evilmartians.com Layered Design for Rails and it's cool to see many similar ideas for where I'd like to see Rails go (and Associated Objects gets a mention). There's lots of interesting ideas and patterns in there, so I highly recommend it!

A fun thing in my ActiveRecord::AssociatedObject gem's design is that we delegate find_by, so in production I just did: User::EmailVerification.find_by(email_address: ".@.").mailer.deliver_later User is an Active Record, while the nested EmailVerification is a PORO! beta.gem.coop/@kaspth/acti...

after four months of private discussions, I have an update on the Bundler and RubyGems situation with Ruby Central: andre.arko.net/2026/03/03/fou…

as I gaze into the camera, it also gazes into me

always wished we had this in the Ruby world https://gem.coop/updates/5/

On Friday, I recorded a @blueridgeruby.com BTS episode with my friend @rhiannon.io, where we get into the crucial topic of marketing for conferences. Full episode here: www.youtube.com/watch?v=B3BB...

Thinking of adding a new gem? There's a lot of info you need to look through to verify gems. So based on feedback from @afomera.dev and @marcoroth.dev here's our initial take on that page: beta.gem.coop/@kaspth/oaken

"Pushing gem to beta.gem.coop/@stephen ... yaml_csp_config-1.2.0.gem uploaded 🎉" Pushed my first gem to my new namespace.

#GemCoop just* launched a public beta for namespaces! gem.coop/updates/5/ * I'm sick and slept until 7pm, so I'm a few hours late, but I'm still super excited about this!

Wow, gem.coop just launched a namespaces preview. They’re on a *tear* launching new features! gem.coop/updates/5/

yesss i’ve been waiting for this!!!

it's been a long day and I forgot to build the email when users' namespaces are approved fixing! (I've already approved your namespace)

I'm excited to be on beta.gem.coop/@kaspth We've got namespaced gems you can use today! Read more here: gem.coop/updates/5/

On Friday, I recorded the first episode of Ridge Notes with Joël Quenneville. We chatted about his upcoming @blueridgeruby.com talk, "State is the First Decision You Never Made." Full episode here: www.youtube.com/watch?v=F5Yp...

this came to me in a dream

rv 0.5.1 is out! Download it on Homebrew or at this link: github.com/spinel-coop/... We now support musl thanks to @case.bike and fixed a performance regression thanks to David Rodríguez. So now setup-rv GitHub Action should be just as fast as setup-ruby!

Have space for 1-2 new marketing clients starting in March. 💗 Retainer (preferred) or project based. Let’s chat!

rvx installs and runs Rails in 8 seconds, vs. gem exec rails in 18 seconds.

a thing about me is: I will grade any bezier on a curve

time to report a bug in a repo with 3085 open issues

rv has a big release, with windows support and gem CLI tools! the fastest way to generate a rails app is now `brew install rv; rvx rails new`. check it out: https://spinel.coop/blog/rv-0.5-cli-tools-windows/

rv 0.5 is out! rv now works on Windows, it supports installing and running Ruby gems as tools (e.g. rvx rails) and running your local scripts or projects with rv run. (rv is a very Ruby manager/installer/runner) spinel.coop/blog/rv-0.5-...
