TIL: The part of an email address before the @-sign, known as the "local-part", is technically case-sensitive, so the emails: jane@example.org and Jane@example.org could both technically exist.

rfc-editor.org/rfc/rfc5321.htm

However, any email server that actually allows for this style of case-sensitive local-part is going to:

a) create a world of pain for the person using the email with upper-case characters, since most software will lowercase compare emails for account registration/login

b) have utter chaos with regards to misaddressing and impersonation. "Oh, you're jane@example.org? No, I'm Jane@example.org"

Like, who really thought case-sensitivity here was a good idea to allow, and why?

Infinite Mac can now be embedded into any website: infinitemac.org/embed

For a demonstration of what this can enable, see @mwicharyMarcin Wichary's amazing "Frame of preference" article: aresluna.org/frame-of-preferen

And for a behind the scenes look, there's a blog post: blog.persistent.info/2025/07/i (spoiler: Marcin was the instigator for all this, conducted over a months-long 100+ message email thread).

Infinite Mac embedding dialog, allowing parameters of a instance to be customized and the resulting HTML to be copied. It uses the Platinum appearance from Mac OS 8.

The famous quotes from The Biography of Guo Tuo-tuo, the Tree Planter (種樹郭橐駝傳):

Quotes on Tree-Planting Experience

"橐駝非能使木壽且孳也,能順木之天,以致其性焉爾。"

- Explanation: This reveals that the fundamental key to successful tree planting lies in following natural laws.
"其本欲舒,其培欲平,其土欲故,其築欲密。"

"其蒔也若子,其置也若棄。"
- Translation: When planting, treat it like a child; once planted, leave it as if abandoned.

Quotes Criticizing Improper Tree-Planting Methods
"雖曰愛之,其實害之;雖曰憂之,其實讎之。"

I created an instance for sharing photos on Fediverse. I invited my family to join my instance. No one came. I begged. No answer.
I'm going to the lawyer to make a will leaving all my family assets to my partner. I don't want any more contact with my family. This is not a joke.
