Very proud of the efforts this team has been putting in to support #passkeys in #rails 🤘

If you have a #ruby on #rails app and want to setup #passkeys in minutes and without diving deep into the internals and complexities, here's a blog post we did about how our new gem does it for you medium.com/cedarcode/passkey…

At @Rails World 2025, I introduced ReActionView, an initiative to explore what's possible in the Rails view layer for 2025 and beyond. As part of this, I announced Herb::Engine, an ActionView-compatible ERB engine built on top of the HTML-aware Herb Parser. #RailsWorld2025

Running Sin City Ruby has been a great source of joy for me. I'm very grateful for all the people it's allowed me to meet and spend time with. Unfortunately, running a conference can also be financially very risky. In this light I've decided that SCR 2025 will be the last one.

Everything we released today in support of #Rails8 is because the Core and Contributing members of the Rails Foundation funded, advised, contributed time, shared resources, & believed in our mission to support the Rails community. We couldn't have done it without them.♥️

For the first time in Rails' history we are able to support this major release with new & updated tutorials, videos, and guides to help you stay up-to-date on new features. This is all thanks to the support of the members of the Rails Foundation! rubyonrails.org/foundation This is why we exist, and this is why these companies support us. Have fun building with Rails 8!
