#Serbia is showing us the way:

The core of the current protest movement has been built by committed students and professors, across all disciplines.

They are calling for:

‘International Academic Solidarity’

Let’s build these networks ASAP!

this is a great and important effort! even with PLC moving out of Bluesky PBC it is important to have more replicas, especially with regional diversity and the ability to "step in" and accept ops if needed. strong endorse work in this direction.

Finally publishing this about PLC! On a day with big PLC news!!

I think the news recasts this piece into more "why that's important", and less doom hopefully!

It's good to have mirrors but I don't believe they'd give us credible exit against a bad PLC directory operator. They'll just stop serving the mirrors before they start dicking us around.

Stopping APIs that only nerds care about is Day 0 of enshittification. It always happens, and it happens first.

Thanks for publicly sharing, this is awesome! 🤩

Are there plans for next meetup?

FYI: I did a 15min talk on open sci comms at #fediday in Berlin:

I’d love to hear your thoughts and join forces.

The thing that still pisses me off about dark forest theory is that it is predicated on the inability to coordinate, and you know say have a society.

@tgoerke.bsky.social a useful ‘letter to the dean’ would need to contain a proposal for the moderation/labbeling method, right?

I’d bet many are (like us) dreaming of ethical ad markets for years?

But I currently believe their emergence ALSO needs UI paradigm shift: the way we are asked to look at them must ‘feel’ different. More Respectful?

Eg: Want to introduce new kind of tax? Offer ‘more direct mandate’ on their use :)

very excited to share this update about bringing AT to the IETF!

last week we uploaded two drafts to the IETF datatracker and today we heard that we’re approved to host a Birds of a Feather at IETF 124 (the formal meeting towards establishing a working group)

Taking AT to the IETF | Bluesky

Last week we posted two drafts to the IETF Data Tracker. This is the first major step towards standardizing parts of AT in an effort to establish long-term governance for the protocol.

Is the claim ‘Establishing an Ethical Ad Market hasn’t been tried before’?

IMO ads are based on limiting agency, without official ‘make ad vanish by donating’ buttons I cannot imagine it.

But biggest obstacle seems to me the general anti-ad ethics within WP communities.

Fondly remember how enticing it felt to me when my fav iOS podcatcher had flattr integration.

Automated microfunding = no cognitive buying decision problem.

Ask @tim.pritlove.org

IMO, the claim ‘ads are the only micropayment scheme that is known to work at scale‘ should include a big fat ‘,YET’.

I wonder if @hennavirkkunen.bsky.social is aware that adversarial interoperability is key to tech sovereignty?

And if so, what is her plan to increase the chances of being able to enforce it against the power of giants?

I've updated my Quarto comments extension to support Bluesky, as well as Mastodon/Fediverse! Any replies on either network *should* now appear in a nice unified interface, along with links and current comment counts.

A term that moves focus towards ‘the structural core of the problem’ would be more productive, IMO.

So, what is the structural core of the problem, nowadays?

Loss of connectivity when leaving a ‘closed’ system?

Paul Fuxjäger @cypherhippie.bsky.social · Jul 22

IMO the term ‘Enshittifaction’ has risen to the top because:

1. Allows to act out against the widespread taboo of ‘you shall not talk about matters around excretion’.

2. Allows to skip analytical work to distinguish between multiple effects we dislike - very useful for defending cynical positions.

we need a new word to replace “enshittification.” the word itself has become enshittified

‘Bluesky Is Dying’ seems to contradict current stats.

It’s just stagnating, eagerly awaiting the next lesson on ‘the dire consequences of an untreated god complex’ by en.wikipedia.org/wiki/Wernher...

Reuters reports on our Eurosky initiative whose goal it is to establish a full, legally compliant #ATProto stack in Europe. But not only that - we’re working on a commons moderation service that can act as an incubator for smaller ATProto devs.

„eingelassen in die bürgerliche Gesellschaft“

„notwendiges Produkt der bürgerlichen imperialistischen Ordnung“

„Zusammenhang zwischen bürgerlicher Normalität und Faschisierung“

Lässt in mir die Frage zurück:

Welcher Teil von Gesellschaft/Ordnung/Normalität ist hier eindeutig NICHT „bürgerlich“?

I think it’s safe to assume that current patterns are not what we should be expect to see when the network gains popularity.

By whom shall those that are supposed to share responsibility be authorized by? What consensus mechanism is available in case patterns evolve to much more complex ones?

What does resource exhaustion attacker need to know in order to be able to generate ‘arbitrary amounts of legitimate operations’?

I cannot (yet) see how a permissioned chain or VCs would be of help?

Looks like the component that carries ALL the weight of ‘credible exit’ marketing claims is exposed to increasing levels of spam/dos.

*absolutely nobody* saw that coming.

First pass at filtering the PLC logs is done

tl;dr ~1/3 are bad operations, driven by 2-3 patterns starting around April 1st (fools day?!), illegitimate (invalid operations) have come to dominate the PLC :[

For the majority of the graph, and the first four spikes that coincide with adoption during the 2024 election cycle, almost all traffic was legitimate.
