Outside of Japan, it’s often possible to identify someone by their last name alone (like referring to Albert Einstein simply as “Einstein”), but in Japan, there are so many people with the same last name that this method doesn’t work. After all, there are 600,000 “Matsumoto”s.

3日50万円で作れるシステムに4ヵ月800万円かけれなくなっている - きしだのHatena SIerに発注したら4ヵ月800万円という見積もりだったものをAI駆使してつくったら3日で50万円でできた、という話が話題になってました。 そこで、SIerでは作るものをちゃんと保証したりしていて文書化は大切である、みたいな指摘が入ってたりした。 でも、よく考えると、それって外注-受託において、作ると言ったものをちゃんと作ってもらったり、作ると言って作ったものにちゃんとお金を払ってもらったりするた...

Memories of Noah Gibbs Responses will be shared with his family

If you have a story about Noah, please share here or in this Google form linked below.

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?

「最初に自分のお金(おこづかい)で見に行った映画」であれば私もヤマトかもしれません。

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。

なんかずっと忙しかった(特にメンタル的に)のが一段落着いた
