Some highlights from #COSCUP D1

[Naruhiko Ogasawara @naru0ga]

西田さんのRmdで書かれたレッスンマテリアルを翻訳する話。AIにメタデータの類を翻訳されちゃうと困るよね的な

[Ruby Taiwan @rubytaiwan]

🔴 Live in TR-514 Ruby Track

Pawel Lisewski — "The Deterministic Rubyist: Taming Your AI Pair Programmer with Nix"

Unenforced READMEs, empty agent sandboxes — Nix makes the dev environment reproducible enough that you and your AI pair get the same one.

#COSCUP2026 #Ruby #Nix

[Ruby Taiwan @rubytaiwan]

🔴 Live in TR-514 Ruby Track

Kasa — "Ruby's ReDoS Defenses: Trade-offs, Rails, and Regexp's Future"

Better regexes aren't the fix. Kasa reads the Ruby core threads behind Regexp's cache optimization (#19104) — Matz approved, but worried about memory.

#COSCUP2026 #Ruby #ReDoS

Nebiyu Elias Talefe (Neba) — "Building Native Mobile Apps Using Rails"

Shipping real mobile apps with Hotwire Native, from the Rails codebase you already have.

#COSCUP2026 #Ruby #RubyOnRails #HotwireNative

[Naruhiko Ogasawara @naru0ga]

前田さんのWebアプリケーションのRTLの話、トーク自体は中国語でおこなわれているので聞き取れない（あたりまえ）だけど話は面白い

[Meng-Ying Tsai (Fumi) @Fumitsuki0802]

🔴 Live in TR-514 Ruby Track

Meng-Ying Tsai — "Locale 何處尋：從 Accept-Language 到 UGC"

Browsers send zh-TW, your locale files say zh-Hant, and Rails Guides just tells you to write "more robust code". So where does locale actually come from?
