🤩 It’s Christmas early! Thanks @gitlab @ItsMissMie @john_cogs 🙏 #gitlabheroes #gitlabhero

The Shopify / Royal Academy Professor of Language Engineer @laurencetratt explains the basics of JIT compilers in this video. We work on JIT compilers at Shopify to support the long-term success of Ruby. youtube.com/watch?v=d7KHAV…

I'm really excited about the official launch of the @gitlab CLI today. Read all about it and get started easily with `brew install glab` - about.gitlab.com/blog/2022/12/0…

@josephjose097 @gitlab @bacharakis Thank YOU for participating and making GitLab more awesome 💖

Received an Awesome Q3 Hackathon 2022 Swag Pack Thank you @gitlab @bacharakis

🦠💥☠️ Watch out! Malicious actors targeting @rubygems started scanning GitHub for "gem install XYZ," "gem XYZ," and "bundle install XYZ" references and auto-generate tracking packages when a given name is not taken in RubyGems. #security #ruby #opensourcesoftware #cybersecurity

🚀💥 Here is the story of me fighting with Ruby concurrency and how I somehow accidentally became a @rubyonrails contributor: mensfeld.pl/2022/11/ruby-c… Enjoy the read 🙏 #opensource #rubyonrails #ruby

I would love to help anyone who wants to make their first code contribution to @gitlab during the Hackathon. Don't forget to RSVP! meetup.com/gitlab-virtual…

“I don’t understand why X was laid off, and their manager also couldn’t tell them why.” With layoffs being more frequent, a thread about how who is let go is often decided, and why it can seem random (even though there’s a system):

100% of Stripe's Ruby codebase, which is the largest single Ruby codebase in the world, is now autoformatted with Rubyfmt. We'll be upstreaming the changes we made soon. I'm very excited.

🦠💥 #rubyfriends watch out! rest_client (not rest-client) went rogue just now! With over 2.6mln downloads(!), it now collects host info upon requirement: my.diffend.io/gems/rest_clie… Detected by @Mend_io #ruby #rubygems #supplychain #opensource #cybersecurity

That's one proud moment for me 🦸. Thanks @gitlab for the wonderful #GitlabHero program🙇. Appreciating contributors in a special way ❤️

I believe that @rubyonrails should gain an officially supported batch/events processing API. Like we have ActiveJob, we need ActiveStream. "The Rails way" is too coupled to the idea of entities instead of streams/events, and that impacts the design and performance of many apps.

Twelve typosquatting research/malicious packages removed from @rubygems this week thanks to us at @Mend_io. As always have a great weekend and stay safe! #opensource #ruby #cybersecurity

🗣️ Including 183 changes since the 1.5.1 release by 26 contributors, we're pleased to announce the release of Crystal v1.6.0! Read all about it crystal-lang.org/2022/10/06/1.6…

Shopify's new HTTP server is Unicorn-esque, but reforks aged Ruby worker processes generationally to yield better copy-on-write memory sharing. Very smart, and kind of obvious in retrospect. Wish I'd thought of it. github.com/Shopify/pitchf…

Struct no more? ::Data has arrived in Ruby. A more modern take on "value objects". Person = Data.define(:first_name, :last_name) me = Person.new(first_name: "Jared", last_name: "White") Works with pattern matching! Details & docs here: github.com/ruby/ruby/pull…

@k0kubun The test app can be found here: github.com/Shopify/pitchf… Real applications tend to have better CoW performance than this synthetic app. From experience it's between 40 and 60% for big Rails apps. But bringing this to 95% makes a huge difference anyway.
