Also please don't restrict bundler and ruby versions like `bundler < 3.0` and `required_ruby_version < 4.0` 🙏
Dear gem maintainers 👋
Rails 8.1 just dropped, but many gems can’t be used because of overly strict gemspec constraints.
Please don’t hard-restrict Rails versions, let us test early and report real issues sooner! ❤️

I find it interesting that every time frozen string literal is discussed, symbols are brought up.
It seems like symbols purpose and semantic isn't well understood. Isn't there a good post explaining what they are and how they're meant to be used?

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.

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.

Back when I joined Unboxed in 2014 there was a bug in the action_caching gem that I fixed for a colleague on another project and released a new version. When he thanked me, I said "no need, I got paid for this - if you'd asked me at the weekend I'd have done it for free" 😂

Ruby Association has 16 Platinum sponsors and roughly $100k in annual income. Platinum sponsorship is ~$3200 (500,000 yen).

When people complain Shopify is too prominent, only main company donor in RC, etc.
WTF folks. As if that was their choice!
Where are the other companies pushing Ruby and Rails with real money and resources to be on par?

The more I think about this, the more I wonder if the best way forward is to transfer rubygems/bundler ownership to the Ruby org.
