I have a long list of keyword arguments, and my line length is a bit too long. I found it's a good time to use Ruby's shorthand syntax for Hash, but it turned out that it was introduced in Ruby 3,1, preventing me using it since Alba supports Ruby 3.0.

@renchap Hi, is there any progress on this topic?

I noticed there’s another JSON serializer gem out there, but their benchmark says Alba performs quite well😆

#rubykaigi Day1 is over. Now it's 3am in Matsuyama. The keynote from @ima1zumi was awesome and gave us nice feelings. TRICK was absolutely amazing, it could change how we look at code. And yes, it's midnight already. I need some sleep for the rest of the conference (2 days!)

I know you love to visit Japan and #rubykaigi is a great reason. Hopefully we make #kaigionrails to be another chance by i18n of the conference.
This year we’ll talk about Kaigi on Rails in English so that you know it better. Stay tuned!

Hey #rubykaigi attendees, the conference is coming, and I have no plan for Day2/Day3 lunch and Day2 dinner. I'd love to talk with Rubyists, especially those from abroad, so please let me know if you can hang out with me!

I'm proud that Alba has now more than 1K stars on GitHub! Thank you for your support, it's so motivating that I can improve it even more!

I always look forward to talking with people with great job opportunities. My expertise is web development with Ruby/Rails and but I can also develop frontend with React/TypeScript. Oh, I always forget that I'm expert of Japanese language, so if you need someone like me, please reach out!

My first post from @justcrosspost created by @solnic.dev who also created dry-rb. So let's talk about "just" and Ruby.
Ruby has `String#ljust` and `String#rjust` methods that return "justified" string. Here's real world example from Rails, "railties/lib/rails/code_statistics.rb" file.

I gave a talk at BuriKaigi (a conference where we all eat fish) about Ruby documentation. The deck is in Japanese but I hope you can enjoy it somehow!

I gave a talk about Alba at TokyoRubyKaigi 12 pre event (前夜祭). In this talk I covered why I created it, how I achieved my goal and some interesting implementation details. While the talk was in Japanese, all slides are in English so I hope you’ll enjoy it too!

Wow now Alba is part of Rage’s OpenAPI features! It’s such a nice thing to have Alba chosen by other developers. I’d like to improve Alba so that integrations will be easier. Stay tuned!

I was inspired by this tweet to make it possible to calculate with Boolean. Yes, it's possible, because it's Ruby.
