📣 EuRuKo 2026 speaker announcement: Chris Hasinski

"From C to Ruby: Porting Doom"

Doom is a 3D engine on 2D maps — dynamic lighting, sprites, variable floor heights. A properly demanding real-time, CPU-bound workload.

Chris shows how to port a large C codebase to Ruby, validate correctness via frame comparison, and measure what it costs.

Brno, 17–18 Sept 🎟️ https://2026.euruko.org/register.html

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!

Rails’ travel_to looks like a simple time-testing helper—but it reveals a powerful pattern.

Temporarily change state → yield → guarantee restoration.

From travel_to and freeze_time to stub_const, Rails uses block-scoped state to make tests safer and easier to reason about.

This week we have 6 years of Bevy ECS, making 2D games using Ruby language, to-policy or not to-policy AI, optimizing Mario Kart builds using Pareto Frontier (I always picked Dry Bones because he looked cool but I guess I was in the wrong this whole time), and much more!

Interesting - Ruby 4.1 (from git) adds native decoding of LEB128 "varints" used in CAR, but I asked the bot to check if it changes anything in my code, and it says it improves the performance a lot w/o YJIT, but with YJIT it's about the same or even worse 🤔 #ruby

./blog.sh 1.2 is out — the import release.

Eight import sources became twenty-two: every social network you are likely to have posted to, the blog platforms, and the Wayback Machine for blogs whose platform no longer exists.

Setting a site up is a conversation now. So is how it looks, with the candidate palette rendered on your own site before you keep it.

And a screen for walking an archive that got too big to scroll.

Programming language support in #Emacs is much enhanced now that #Eglot brings robust support for #LSP (Language Server Protocol). Eglot is established and mature, and opens up the wealth of sophisticated language support in that ecosystem.

@i_dabble For #Ruby, you should start with https://emacs-lsp.github.io/lsp-mode/page/lsp-ruby-lsp/

and for how to get Eglot working, start with the Emacs documentation: https://www.gnu.org/software/emacs/manual/html_node/eglot/Quick-Start.html

I was wondering why completion for Ruby was so much better in Vim, compared to Emacs. Turns out ruby.vim does a lot more than propose words it finds in open buffers: https://github.com/vim-ruby/vim-ruby/blob/master/doc/ft-ruby-omni.txt
Is there anything like that for Emacs?

I just released v0.4.0 of Mimas, which replaces `ruby-install` and `chruby` with `rv`.

Not only is `rv` an order of magnitude faster to install #Ruby (because it just downloads a precompiled binary), it also combines all the best parts of `rbenv` and `chruby` to help manage different Ruby versions.

I've even switched my local dev environment to `rv`!

Satoshi Tagomori is speaking at EuRuKo 2026.

Ruby committer, OSS developer, PdM at SAKURA internet.

His talk – Stacking Boxes – covers Ruby Box, the new feature in Ruby 4.0 that's still being actively developed. The separation and isolation it provides is useful for development, deployment and testing. What it is, when to use it, why to try it.

@lobsters As is Ryan Bigg’s post disagreeing with the approach (support Hanami instead).

I see value in both futures for #ruby and I believe a healthy ecosystem is one with diversity (ha!) of perspectives and choices.

To me, the most important thing is that this conversation is even happening.

I disagree with use of the term “virtue signaling”, as I find it to be a condescending and conservative phrase, but the rest of the logic is worth considering.
