Project mention: Presentation Slides for RubyConf Austria 2026 Talk "Frontend Ruby on Rails with Glimmer DSL for Web" | dev.to | 2026-06-02

In about 1 minute, I scaffolded a Hello World desktop app from scratch and then packaged it as a native executable on the Mac. Attendees were impressed. So, I’ve participated in presenting 2 events at this conference.
