  • 📅 If you wanted to attend Rails World (mentioned last week), I hope you got a ticket as apparently they sold out in under 20 minutes. A second, smaller batch of tickets is tempted for a later date, however.

  • 🇸🇪 If you want an event you can still get a ticket for, Baltic Ruby takes place in Sweden next month (June 13-15) with Matz attending in person – his first talk in Europe for some years. He's also speaking at Red Dot Ruby in Singapore in July.

  • 💻 DHH's latest thing is "moving continuous integration back to developer machines" in a further effort to reduce complexity.

  • 📉 Over on Reddit, someone has observed that the new Ruby 3.3.1 seems to have resolved some of Ruby's recent memory leak issues.

  • 🐦 Ruby LSP now supports Go to Definition for methods.
