“With Ruby, We Stride” is my TRICK in progress for @RubyConfTW, just like I promised after #RubyKaigi Boast #CodeParty 4 fun facts: • In 1998, Taiwan introduced the animated “Little Green Man” on pedestrian signals, combining function and charm to enable countdown timers (1/3)

我每天的興趣是看票賣得怎樣，召集人都要變成著急人了，終於快要損益兩平，好辛苦，下一個 milestone 是 After Party，希望也可以達成。

型システムのしくみ ― TypeScriptで実装しながら学ぶ型とプログラミング言語

遠藤侑介 著 184ページ A5判 ISBN：978-4-908686-20-7 型システムがようやくわかった！ TypeScriptのサブ言語に対する型検査器を実装しながら、実用的なプログラミング言語の機能が型システムでどう実現できるかを見ていきます。AST（抽象構文木）や処理系の実装を通してプログラミングへの理解を深めるように、型検査器の実装を通して「型システムのしくみ」を覗いてみましょう！
