In 2025 we need philosophical attitude more than ever: being calm, thoughtful and meaningful. I want to be that kind of person. In this complex era, I want to dig into things, talk with people, think about problems and make decisions. I want to be communicative, respectful and free.

Inoreaderとn8nの連携、何ができるか考えてみたけど、「読むに値するか」をAIでスコア化すれば、かなりの数の記事をフィルターアウトできるな。普通にやるとスコアリングのロジックで詰まりそうだけど、AIでそこを突破できないか。

自分を公的な人物として引き受けてそれに見合った振る舞いをする、というのは言うほど簡単ではないし、それをしている人は尊敬に値する。ソーシャルメディアの影響で公私の境界が曖昧になる時代には尚更。

I’m really curious to know what is going on here. Rubygems is such an important part in Ruby ecosystem and everyone benefits from it. I’m willing to help if I could do something.
Hey, #ruby folks! I've been one of the #RubyGems maintainers for the last decade.
Ruby Central has forcefully taken control of the RubyGems organization on GitHub, the `rubygems-update` and `bundler` gems on rubygems[.]org, and more.

My talk at #RailsWorld 2025 was uploaded! I really appreciate their hard work of the team.
This talk includes lots of demos using Neovim to read through the code (not because of DHH using Neovim, I'm a big fan of Vim since years ago😁), hope you enjoy it!

成田空港の手荷物受け取り、おそらく乗客がみんな外国人なので入国審査で溜まっており、そのせいでベルトコンベアが埋まってしまいこっちも詰まっている。仕組みに難がある。

日本で15000円のカンファレンスチケットが高いと言われる状況が続くなら、遠からず海外カンファレンスから日本人の姿は消えてしまうかもしれないし、それは日本にとってはものすごい損失なので、そうならないようにやっていきたいものです。

日本でたくさん食料を調達してスーツケースに入れ、お土産を買うたびに日本から持ってきたものを食べ、さらに現地のスーパーで安いお菓子を買い込んで空港に持ち込むと、食費をかなり節約できそう。空港だとクッキー1枚で600円とかだからやってられないけど、水と違ってお菓子は持ち込めるのはでかい（手荷物検査で水没収して空港内で1000円とかで売るのは邪悪よな…）
（値段を比較すると、空港内ではコーヒーとかはあまり値上がりせず、水やお菓子が相対的に高い）
