RubyKaigi 2024 - YouTube

RubyKaigi, essentially Ruby’s ‘home’ conference in Japan, took place in May, and now you can enjoy it from wherever you are. With a mix of Japanese and English language talks, there are some great talks worth your time, including Vinicius Stock on the state of Ruby dev tooling, Maxime Chevalier-Boisvert on breaking the Ruby performance barrier, Koichi Sasada on Ractors, Takashi Kokubun explaining how YJIT makes Rails faster, and Emma Haruka Iwao showing off Ruby’s role in a world record Pi-calculation attempt.
