Ruby::Box: Rethinking Code Reloading with Isolated Namespaces
Ruby::Box: Rethinking Code Reloading with Isolated Namespaces By simi January 25, 2026 — Praha, Žižkov Ruby lives in a single global object space. Classes, modules, and constants can see each other, reopen each other, and override each other freely. This is one of Ruby’s greatest design strengths: it enables expressive DSLs, powerful metaprogramming, and a level of flexibility that few languages c
RatatuiRuby — Terminal UIs in Ruby
Inline Viewports Standard TUIs erase themselves on exit. Your carefully formatted CLI output disappears. Users lose their scrollback. Inline viewports solve this. They occupy a fixed number of lines, render rich UI, then leave the output in place when done. Perfect for spinners, menus, progress indicators—any brief moment of richness. class Spinner def main RatatuiRuby.run(viewport: :inline, heigh
Ruby Array Pack Bleed / nastystereo.com
With the release of Ruby 4.0.0 on Christmas, I decided to revisit integer handling bugs within Ruby MRI, the canonical implementation of the Ruby programming language. This lead me to discover a vulnerability which allows reading memory out of bounds of the allocated string buffer. Although memory disclosure vulnerabilities have a serious impact, it is important to note that affected method is rar

Dear Rubyists: Shopify Isn’t Your Enemy
I’ve been meaning to write a post about my perspective on Open Source and corporate entities. I already got the rough outline of it; however, I’m suffering from writer’s block, but more importantly, the whole post is a praise of how Shopify engages with Open Source communities. Hence, given the current climate, I don’t think I could publish it without addressing the elephant in the room first anyw
Why I'm not rushing to take sides in the RubyGems fiasco
We are in the midst of a Ruby drama for the ages. I'm sure a bunch of people figured we were all too old for this shit, but apparently we are not. This debate has been eating at me ever since the news first broke, but I've tried to keep the peace by staying out of it. Unlike most discourse about what's going on, my discomfort stems less from the issue at hand—what Ruby Central did, how they did it

The Ruby community has a DHH problem
David Celis recently published a thoughtful piece on Rails governance in response to the latest troubling blog post from DHH, the creator of Rails. Like David, I’ve also been troubled by DHH’s recent output and the harm it is causing to the Ruby community. I think it’s worth taking a moment to analyse DHH’s post in more detail and make it clear exactly why it’s so problematic. In his post, DHH com
