DELTA Inc. (Headquarters: Shibuya-ku, Tokyo; CEO: Tetsuro Tan) announces that it will exhibit a booth as a Platinum sponsor at "RubyKaigi 2026" from Wednesday, April 22 to Friday, April 24, 2026.

RubyKaigi is an international conference about the Ruby programming language. Rubyists from all over the world gather to share deep technical knowledge about the Ruby interpreter and related technologies. It is widely supported by the developer community as a place where prominent Rubyists from Japan and abroad, including Ruby's creator Matz (Yukihiro Matsumoto), take the stage to discuss the latest trends and future of Ruby.

We will be holding a "Garapon" lottery where you can win technical books, so please be sure to stop by the DELTA booth.
