Wikipediaに代表される「Wiki」は、多くの人々に使われるソフトウェアに成長しました。
「XP(エクストリームプログラミング)」は、現在主流となりつつあるアジャイルな開発方法論です。
設計の定石集である「デザインパターン」は、今や開発者の必須知識となっています。
Wiki、XP、デザインパターン。一見、何の関係もなさそうに思えるこの3つは、実は同じ起源から発生した兄弟です。
しかもその起源は、ソフトウェア開発とは何の関係もない異分野の人である、建築家クリストファー・アレグザンダーの理論に端を発しています。
本書では、アレグザンダー(パターンランゲージの発明者)、ウォード・カニンガム(Wikiの発明者)、ケント・ベック(XPの提唱者)らが織りなす40年の歴史物語を辿りながら、優れた創造を行うための共通原則に迫ります。
Comments from Mr. Eto
私は6年前よりWikiの設計思想について調べてきました。
建築家クリストファー・アレグザンダーの思想にその答えがありました。
アレグザンダーとWikiを巡る歴史物語をまとめた本を書くことができました。
「デザインパターンのどこがいいのかわからん!」
「XPって本当に役に立つの?」
「Wikiに何を書けばいいんだろう...」
そう思っているあなたへおすすめします。
デザインパターン
ソフトウェア開発におけるデザインパターン（型紙（かたがみ）または設計パターン、英: design pattern）とは、過去のソフトウェア設計者が発見し編み出した設計ノウハウを蓄積し、名前をつけ、再利用しやすいように特定の規約に従ってカタログ化したものである。

Conclusions
Wiki is not popular except Wikipedia
Original wiki was not super easy
Various wiki services are used by maniac people
Modern wiki's are very useful
e.g. Scrapbox
Let's use Scrapbox!
