概要

WHIは、今まさに「レガシー」な技術のアップデートに日々奔走しているところです。
ぜひ皆様の、旧環境の保守での苦労話や、逆に古い技術とうまく付き合うための知見、また刷新にあたっての成功体験や学びなどをどしどし書いてください!

規模の大きな抜本的な刷新話から、古いバージョンの言語でのプログラミングにおけるちょっとしたTipsまで大歓迎です!
否定的な文脈で使われることも多い「レガシー」を、資産としてのレガシーとして継続し続けるためのノウハウをぜひみんなで共有しましょう!

こんな人におすすめ

  • 「レガシー」なシステム・ソースコードを保守・刷新した経験のある方

  • 昔から使っているツールを改善したり直したりした経験のある方

  • 具体的には……

    • 退職者が作ったけど動かないツールを読み解いて動くようにした
    • ドキュメントが無かったのを整備した
    • 20年来のシステムに自動テストを導入した

などなど!
