Stable Outbox Collection Pages

3/

If the page with 3 items contains the 3 oldest items, then —

Every time a new items is added to the collection, then every single collection page will change. I.e., they all churn.

Which means that all cached copies of any collection pages will be invalidated.

Which means a static site generator will have to regenerate all of them again.

Etc.

BUT, if instead —

Be kind to open-source developers.

Behind most open-source projects is a person donating their time and energy to help others.

They are often working on these open-source projects after their day jobs, family obligations, and everything else life demands of them.

Is that the Granville Street Bridge?

Here is something related:

There is a stable algorithm to find them (community structure in graphs), too:

(One of the authors of the paper (Massoud Seifi) has even worked on Fediverse software.)

"zoner" is a play on the host of FireSide Fedi — Anthony Zone.

Both his family-name ("Zone"), and his Fediverse handle "ozoned".

AFAIK, this was the first portable computer.

Doesn't seem to do that for me.

Memes aside, if you are a Fediverse developer, it can be useful to pay attention to what others are doing. Notice what works for them and what doesn't. What their trade-offs are. Etc. And, if there is anything we can learn from them.

#BitSocial #FediDev

On moving an actor's content.

1/

One of the things that comes up on the Fediverse from time to time — is the ability for people to move their accounts.

For example, someone started off at:

＠joeblow＠example.com

But, now wants to "move" to:

＠misterx＠host.example

There is a mechanism to do that.

That mechanism moves their followers, their followees, BUT —

It does NOT move their content over!

That is a problem. Could we address this‽

Some small rural towns stay connected through Facebook groups.

If you want to reach people in that small town, for social or commercial reasons — you post to that towns' Facebook groups.

...

What could the Fediverse and Social Web learn from this?

#FediUX #FediverseUX #SpreadFediverse

OH: We should call it [the Fediverse] the "Sexy Social Web".

Awesome!

Loops works with these new Collections, too.

The "uploadMedia" endpoint?

I assumed resumable uploads would be incompatible with that API endpoint.

If it isn't incompatible, could use that.

I can think of different ways to support resumable uploads with ActivityPub, but — just to see what others are doing —

PeerTube seems to have resumable uploads already.

PeerTube seems to use this protocol for it:

https://github.com/kukhariev/node-uploadx/blob/master/proto.md

I like that it uses Content-Range in the protocol. I would have done the similar.

#ActivityPub #ActivityStreams #FediDev

It seems as if the uploadMedia ActivityPub extension does not provide a way to resume an upload that didn't previously compete.

https://www.w3.org/wiki/SocialCG/ActivityPub/MediaUpload

If, for example, you are working with large files (such as video files) this would matter.

Because if you uploaded 1GB, and the upload stopped, you would want to resume at where it stopped, and not have to upload from the beginning again.

This would be important for ActivityPub C2S adoption.

#ActivityPub #ActivityStreams #FediDev

Just thinking out loud —

If we wanted to support resumable uploads in C2S API, then — we probably need some URL to upload the file chunks to.

…

When a user POST to their own outbox, the HTTP "201 Created" response will have a "Location" header that provides a URL.

Maybe that could be used as the upload URL.

Or, maybe the JSON-LD document at that URL might contain a URL under the "object" field that could be used as the upload URL.

Other options too

Done:

(Let me know if you need more information added to it.)

@silverpill

Like I said, people are of course able to decide for themselves.

Including disagreeing with me.

...

But, I feel "building in open" should not be in the same place as specifications documenting standards.

What should the file-extension for ActivityPub / ActivityStreams documents be?

I.e., for application/activity+json data?

I've been using .activity

Ex: filename.activity

(The extension cannot be .json or .jsonld if you want to be able to detect it just based on the file-extension.)

What do you think?
