Can Bundler Be as Fast as uv?
At RailsWorld earlier this year, I got nerd sniped by someone. They asked “why can’t Bundler be as fast as uv?” Immediately my inner voice said “YA, WHY CAN’T IT BE AS FAST AS UV????” My inner voice likes to shout at me, especially when someone asks a question so obvious I should have thought of it myself. Since then I’ve been thinking about and investigating this problem, going so far as to give a presentation at XO Ruby Portland about Bundler performance. I firmly believe the answer is “Bundler can be as fast as uv” (where “as fast” has a margin of error lol).

One of my intentions with the Short Ruby Newsletter was to create an archive for these types of discussions. So, next time someone suggests that Rails might be the problem at GitHub, here are two people who can confirm it was not.

The Tailwind community has become too dogmatic about utility-only. Tailwind is utility-FIRST, not utility-ONLY. And @utility and @apply are criminally underused. And here is why this matters...

I'm making another attempt to get a `deep_freeze` method added to Ruby. Core folks have rejected proposals for years, until Ractor came along and we got basically the same feature in `make_shareable`. But deep freezing should be its own feature.

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.

The two most effective ways your company can support open source: 1. Let your developers have time for open source work. 2. Give each of your developers an annual budget to allocate to whatever OSS projects they think are important.
