Anatomy of an E2EE ActivityPub Note in Enigmatick

Over the break I spent some time revamping my structs and enums for handling #E2EE #ActivityPub exchanges. This is what I have at the moment for the initial Create from the client (this is subject to change).

The mention of mls-tester has an [at] to avoid triggering my automatic webfinger resolution.

I've adopted the mediaType and encoding attributes from the draft ActivityPub specification. And I've standardized the Welcome message to incorporate those.

The Create includes the Welcome and a VaultItem as instruments rather than being sent as separate activities. The Welcome can include any number of recipients, so one within the activity should be sufficient.

The VaultItem is specific to the #Enigmatick client and isn't intended to be federated. That's how I'm handling ongoing access to the decrypted data; the VaultItem is a symmetrically encrypted representation of the original content that can be safely stored on the server for repeated use by the client. I'll need to eventually update the @context with that extension.

I saw my aunt this weekend. I always admired her growing up: she was a dedicated dancer, bird watcher, traveler, and general arts-enjoyer. I took up ballet and piano because I wanted to be just like her.

I just found out that she started all of those hobbies after she got sober in her 40s, shortly before I was born. Her defining characteristics, in my eyes, have occupied less than half of her life.

It was a nice reminder that you can start a new chapter of your life whenever you’d like.

If Strava is enshittified, just go for a run.
If Google Maps is enshittified, run the streets you know.
If Facebook is enshittified, text your friend to make plans.

The solution isn't always building a new platform or switching to an OSS model. You can also engage less.

An interesting diplomatic communication today from #France toward #Russia: https://onu.delegfrance.org/france-reaffirms-its-support-for-international-space-law

"France reaffirms its support for international space law, which must be complemented by confidence-building and transparency measures, as well as by the development of norms of responsible behavior.

"In the face of threats, our primary safeguard remains compliance with the international legal regime applicable to outer space, and first and foremost the 1967 Treaty, which is its cornerstone.

"In this regard, France reiterates its concern about the potential placement of weapons of mass destruction in outer space, which would constitute a flagrant violation of Article 4 of the 1967 Treaty, and a major threat to international peace and security.

"In addition, France is involved in ongoing discussions in the competent bodies on ways to prevent an arms race in outer space. The most appropriate approach to this end is the development of norms of responsible behavior that promote mutual understanding and reduce the risks of uncontrolled escalation. These norms could serve, if necessary, as a basis for the subsequent development of new legally or politically binding instruments."

I love what Tauri has done, a lightweight version of Electron, where you author the backend code in Rust.

But while I love Rust, I do not love it for app building, and I wanted to have that HTML-model for programming but available in Swift.

I used assorted AI tools to port Tauri to Swift (it still reuses the big chunks of code from Tauri), but now you can write HTML desktop apps in Swift:

I finally managed to build a image for my #Raspberrypi using #disko.

The Pi boots with UEFI and has a LUKS paritition containing BTRFS.
There is still a lot to do but I'm getting really close to a usable state.

I still find it very satisfying to build these kind of things with #NixOS

@melvincarvalho just shared https://socialdocs.org/ on the SocialCG mailing list. It looks like a great resource for ActivityPub info. I see a few mistakes, but in general it seems to be pointing in the right direction.

Dem „Gegner Honig ums Maul schmieren, aber wenn wir endlich soweit sind, dann stellen wir sie alle an die Wand."

Sie haben auch schon ein paar Pläne für die Zeit nach „der Machtübernahme“, nämlich: „Volksfeindliche Medien verbieten.“

Denn: „Die Zeit, in der das deutsche Volk sich erhebt wird kommen. Es ist unsere Zeit!!!“

The Second-Order Streisand Effect is a social phenomenon where if a party makes an effort to censor information, discussion and news about the censoring attempt paradoxically leads to an increased awareness of Barbra Streisand, a musician whom most Zoomers would probably have never heard of if not for the Streisand Effect
