Detecting the real IP of a Cloudflare'd Mastodon instance

NB: This will not work for instances that proxy outgoing requests!

Reading the docs

I wanted to find a way to detect the real IP address of a Mastodon/Pleroma/Misskey/etc instance hosted behind Cloudflare. How to do that? Well, it's federated, which means I can probably get it to send a request to a server of mine! And how to do that? I tried reading the ActivityPub spec. The following caught my attention:

Servers should not trust client submitted content, and federated servers also should not trust content received from a server other than the content's origin without some form of verification.

vimで使うキーの機能使用頻度と打ちやすさの整理

vimで使うキーの機能使用頻度と打ちやすさを整理してみました。 今回整理したのはnormalモードについてだけです。 機能の使用頻度と打ちやすさは、完全に個人の見解です。 キーボードによっても打ちやすさは変わると思います。

すべてのキーを網羅しているわけではありません。
