I strongly agree with Weaver's "Callbacks Are Not Invariants": callbacks can't keep their promise, writes go through one door. The ingress doesn't own the invariant. The aggregate does. And the persisted fact, not the outbox, makes effects recoverable. blog.arkency.com/ingress-is-n...

As a Polish person I endorse this comparison to our national sport 🍄‍🟫🍄‍🟫🍄‍🟫 „I tend to treat performance gains like mushroom hunting. When you find a mushroom, it usually means that it’s an area where they grow well, and that no other mushroom hunter has passed by recently.”

New post: A timezone bug that hid for months — using Time.now to get DST offset for historical dates. Simple fix, but a good reminder to test with explicit timezone manipulation. blog.arkency.com/the-timezone...

That feeling when a single-purpose class eliminates 100+ instances of `message << " | "`. Ruby 3.4 forced my hand, but I'm not complaining. blog.arkency.com/the-joy-of-a...

I was recently reminded that not everyone fully understand what the frozen string literal magic comment is about. So I figured it was the occasion for another deep dive. byroot.github.io/ruby/perform...

byroot.github.io

Frozen String Literals: Past, Present, Future?

If you are a Rubyist, you’ve likely been writing # frozen_string_literal: true at the top of most of your Ruby source code files, or at the very least, that you’ve seen it in some other projects.

Serious question: What were the drivers behind enforcing Rubocop’s Style/CaseEquality rule (prohibiting ===) in your codebase? „rubystyle.guide said so” is not the answer that makes me satisfied.

Why do we do this ourselves? We are feeding the rich with our knowledge without any benefits in return. Instead, they make content hard to read, hard to search, hard to edit, and hard to follow. And hire algorithms to throw trash into our feeds. More: dudulski.pl/2025/10/15/f...
