Rubycon ItalyLast Survival Kit before Rubycon: food.
Piadina with squacquerone for lunch. Adriatic seafood for dinner. Friday night: Toga Party on the beach. Saturday: walking tour through Rimini.
What if Ruby could run at the center of an event-driven system?
Maciej Mensfeld built Karafka. His deployment handles 500M messages a day. He's also on the RubyGems security team, hunting malicious packages.
Which Ruby frontier makes you most curious in 2026?
Ruby keeps landing in places nobody expected a few years ago. Music, microcontrollers, AI products, edge computing. Where do you think the most interesting work is happening? If we missed one, tell us.

Yesterday's Rose#GitHub Pages CI auto-build and deployment thing depends on the github-pages RubyGem.
Unfortunately, there's a snag: github-pages gem was last updated in 2024, and long story short, some dependencies of github-pages v232 are not compatible with Ruby 4.0. While deploying stuff to GitHub works just as well as it did before, if you have Ruby 4.0 locally, good luck building the site locally for previews.
The solution, of course, is to switch to a locally run version of Jekyll and just deploy static site from a branch without Jekyll processing. Another advantage being that you can also switch to the current version of Jekyll, or, hell, switch to some other static site generator. *Another* advantage might be that once you do that, you can, you know, switch to #Codeberg Pages or something.
I think I'll start by migrating this one #Python project's documentation site from Jekyll to Sphinx! I mean, while I love Jekyll, this is a Python project, might as well use a Python thing.
Packing for Rubycon? May in Rimini: 15-25°C, mild and pre-tourist season. Pack a light jacket and a swimsuit.
Event in English. Cards accepted almost everywhere. Questions? Ask in the replies.

I'd have never figured this out myself…
Those damned Germans… 😛
Top liked open PR in the repo by far:
They also said they would prefer a PR that instead just reverts that change, so they can discuss that, so one guy opened such second PR (https://github.com/rails/rails/pull/56842), also no reaction
I can't believe the #Rails team is still basically ignoring this after so many people joined in, apart from a few comments complaining that they don't want to be tagged… 😑 #ruby #rubylang

What if Ruby rewrote its own engine in Rust?
That's YJIT, built inside CRuby at Shopify. Railsbench runs 65% faster on Ruby 3.3.
