Noah's wife has asked me to collect stories about Noah for the benefit of his children. They couldn't see how deep and complex and layered his life was, and she would like them to be able to understand that some day.

He thought Ruby was the best way to do (fill in the blank) and he wanted to share his knowledge as widely as possible. His kindness and generosity extended into every corner of his life.

Noah's passing was sudden and very fast. He did not suffer. He is survived by his wife and children.

Noah Gibbs (codefolio, YJIT team, Rebuilding Rails author) has passed away.

His big dream in life was to help build the Ruby community up. He wanted to be like the folks who worked to create the railroads during the industrial revolution.

Looking to impress your Ruby friends by calculating the largest known prime, 2**136_279_841-1?

On Ruby 3.4.0-preview2 and earlier, 2**136_279_841-1 logs a warning and returns Infinity 😔.

わたしが「最初に映画館で観た映画」は、東映動画の「長靴をはいた猫」です。もう半年早ければ「ホルスの大冒険」だったのですが、これは中学生の時文化祭で自主上映会を開催して観ました(16mmフィルムをレンタルした)
その後、ホルスはVHSテープを購入しましたが、もはや再生機器がない。

Paul Grahamが、人気が出るためにはプログラミング言語は人気のあるシステムのスクリプト言語でなければならないと言ってましたね。CはUnixのスクリプト言語。それで言えばPythonは機械学習分野のスクリプト言語の地位を確保したのかも。

SNSのソーシャルグラフ、フォローと非フォローのデジタルな制御じゃなくて、相手の投稿をupvote/downvoteしていった累積のアナログ値でいい感じに表示をコントロールするっていうのはできないものか。「このひときついなー」って思ってもunfollowを相手に突きつけるほどでもない時にdownvoteして表示頻度を減らせる減る的な、
