久しぶりにPixelbookを引っ張り出してきて再設定したけど、なんの遜色もなく普通に動く。macOSほどのキビキビ感はないのだけど、それは元々だし、発売当初と比べても遜色ない。再来年にはアップデートされなくなってしまうというのはもったいない。

世田谷区の粗大ごみ、オンライン決済が可能になっていた。今までコンビニでシールを買わなければいけなかったのでちょっと便利になったのかも？ただ、コンビニで買うシールは番号書いてそのままゴミに貼って出せたけど、オンライン決済の場合は貼るシールがないけど、どうなる？
もしかして自分で何か印刷して貼る？令和にまさかねえ。きっと番号とか書かないで出しても回収してくれるに違いない！と思い切ってオンライン決済。そしたら、みごとに自分で紙を印刷して番号書いてテープで貼れ、というものだった😩
分かるんだけど、かえってめんどくさくなってない？

Music I get recommended on YouTube nowadays are quite nasty. AI generated covers are pretty well done and it's hard to tell whether it's human made or AI generated. I can only tell from the cover image unless it's stated. The problem is, I kinda like AI generated covers.

Signal API is now available on Chrome for Android.
A user deletes their credential on the website, but the passkey remains in their passkey provider. The next time they try to sign in, the passkey provider offers a passkey that no longer works. A sign-in attempt will fail and this isn't ideal.

デパートとかビルの出入り口でモスキート音が鳴ってるの、気付くととても不快。自分の耳は割と悪い方だと思うので、大人でもギリギリ聞こえる音域だと思う。あれは虫とかが入ってくるのを防ぐためなんだろうか？
