🦠💥☠️ 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: https://t.co/2VoxKo9uxm

Enjoy the read 🙏 #opensource #rubyonrails #ruby

[Siddharth Asthana @Asthana31]

I would love to help anyone who wants to make their first code contribution to @gitlab during the Hackathon.

Don't forget to RSVP!

“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: https://t.co/fs4DOwkUJP

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

[Maciej Mensfeld @maciejmensfeld]

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.

[Maciej Mensfeld @maciejmensfeld]

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

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.

Struct no more?

::Data has arrived in Ruby. A more modern take on "value objects".

Person = Data.define(:first_name, :last_name)

me = https://t.co/pC2yrbvXfI(first_name: "Jared", last_name: "White")

Works with pattern matching!

@k0kubun The test app can be found here: https://t.co/6Xs7wdciSX

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.
