However @bnewbold pointed out, correctly!, that there were cheaper options available. If we used even Linode's block storage, it would be cheaper (but still expensive) for the storage component, and this is true bsky.app/profile/dustyweb.bsky

In fact @bnewbold and alice had gotten the server down to just close to $200/month in their estimate, much much cheaper than I had, by choosing a dedicated server plan. Much cheaper!

But there's a problem though; that's cheap because you've got a server that has a dedicated disk...

Christine Lemmer-Webber replied to Christine

Even if we look at the dedicated hosting provider that @bnewbold provided in June and scale the cost to the pre-election storage requirements, we are adding on a massive amount of cost every month, over $400/month more.

Christine Lemmer-Webber replied to Christine

But worse, we have reached the limits of what is possible to do with a dedicated server. We *have to* move to abstracted storage from this point forward because we're starting to hit the limits of what's offered for cheap dedicated storage on one machine. And this number will only grow, and as said previously, is growing at an enormous rate.

flaeky pancako replied to Christine

@cwebber honestly blogs are a more 'credible exit' than a bsky pds ..

Christine Lemmer-Webber replied to Christine

I have spent a lot of time focusing on the cost of storage, but storage is only one cost required. These estimates have been done so far against servers that *nobody is actually using*. The cost of servers that people are using will be much higher, because more needs to happen than just store things.

And that is not even to mention the challenges with administrating, dealing with takedown requests, illegal content, etc, which are probably much more serious.

Christine Lemmer-Webber replied to Christine

Let's take a break, the analysis of server costs is boring and I don't like doing it, and I'm sure people will throw numbers at me of the absolute race-to-the-bottom hosting numbers they can find to store and run all this stuff, but really that's not interesting to me.

Let's do a comparison.

Christine Lemmer-Webber replied to Christine

Remember that the idea of "fully self-hosting" on Bluesky/ATProto at this point is primarily abstract; nobody is really doing it. But of course there's a place where tens of thousands of people are running their own servers for millions of users, and that's the fediverse/ActivityPub.

Christine Lemmer-Webber replied to Christine

As said, tens of thousands of people are self-hosting *today*. Fediverse software doesn't just scale up, it scales *down*.

GotoSocial is cheap enough on resources where you can run it for family and friends on a raspberry pi or spare laptop you have sitting around.

Christine Lemmer-Webber replied to Christine

Now you're hitting the point in this thread where some of you may be thinking "aha! this is where Christine is saying that the fediverse/activitypub are awesome and atproto is terrible!"

you have NO IDEA HOW MUCH I CRITICIZE THE FEDIVERSE ALL THE TIME, I do it all the time, and will later here

Christine Lemmer-Webber replied to Christine

The fediverse has a lot of flaws. Oh trust me, we're gonna get to that.

But comparison-wise: what I mean to say is that architectural decisions matter, and scaling up isn't the only thing that's important, *scaling down matters too*.

If you care about decentralization, anyway.

Christine Lemmer-Webber replied to Christine

Now look, we're about 1/3 of the way done here, there's a lot more to say, and a lot more said in my article, it's about 24 pages long if you print it out.

This is because in the age of TikTok I somehow have decided to model myself after David Foster Wallace, sorry

"Consider the Fediverse" I guess

Christine Lemmer-Webber replied to Christine

But now, I will break for lunch. Enjoy your intermission because I will be back. We still have to get through the remaining 2/3 of the analysis, after all.

======= LUNCH BREAK HERE =======

Fifi Lamoura replied to Christine

@cwebber Thanks for doing this, it's an amazing analysis and contextualization!

Christine Lemmer-Webber replied to Christine

Okay I am back from lunch, time to resume my analysis thread for "How decentralized is bluesky really?" dustycloud.org/blog/how-decent

I have been receiving a lot of notifications, I am not reading any of them until I finish with this so bear with me, BEAR WITH ME, we're gonna make it through

Christine Lemmer-Webber replied to Christine

And before we make it any further can I say that I watched a nice medley of David Bowie and Cher singing, and it was so lovely youtube.com/watch?v=KPlN8RBP-W

@mlemweb said "of course it's very heteronormative despite having two queer coded icons on the stage and ISN'T THAT THE WAY I guess

Christine Lemmer-Webber replied to Christine

But where was I? Oh yes. We had talked about why PDS'es aren't enough (blog/google analogy), relative costs of hosting things on ATProto vs ActivityPub, etc etc

But we haven't gotten into the really interesting parts which are the structural analysis stuff, so let's move onto that

Christine Lemmer-Webber replied to Christine

Now you may be saying, "Christine, this is really unfair, because you're looking at ActivityPub servers which are only dealing with a small amount of the network, what if it were an ActivityPub mega-node? What are the costs THEN huh?" and "What if we hosted just PART of ATProto?"

What then INDEED

Christine Lemmer-Webber replied to Christine

ATProto is not designed for the Relay and AppViews to only hold part of the network, not *really*, and ActivityPub is. We'll get to this in a moment.

But Bluesky actually has good justification for this! I will defend it insofar as Bluesky was making a serious *design decision*

Christine Lemmer-Webber replied to Christine

Remember the directive that Bluesky was given: develop a decentralized protocol which Twitter can adopt. That informs a lot of things, and has meant that Bluesky was really very ready for this moment!

If you're an ex-X-Twitter user then by god, you're going to be amazed! It's just like Twitter!

Christine Lemmer-Webber replied to Christine

This informs some other things:
- Bluesky's gotta scale BIG and do so FAST (scaling down: not a priority at all)
- It has to be something Twitter can adopt (of course, not anymore, but initially)
- Everything on ATProto is public (yes, everything, including your blocks btw, we'll get to that)

Christine Lemmer-Webber replied to Christine

But here's the other thing. People have trouble with the fediverse! All those decentralization decisions get in the way, my god, you've got to choose a server, search doesn't work well (actually it could but it's a cultural thing, different topic), and worst of all:

Sometimes you DON'T SEE REPLIES!

Christine Lemmer-Webber replied to Christine

Actually all these critiques of the fediverse are TRUE, these are known challenges, and actually it's not really so bad, but it could be better, and at any rate, Bluesky made a major decision to simplify a lot for new users, and they have. Things seem to just work for people! Incredible!

Christine Lemmer-Webber replied to Christine

The thing you often get seen thrown around is "it's amazing, I had no idea a decentralized protocol could just work like that! How on earth did they solve that in a decentralized system and so FAST too!"

It's simple: all those things "just work" because Bluesky is centralized.

Christine Lemmer-Webber replied to Christine

Now yes, they are using decentralized techniques. Remember when I said content-addressed storage is a good idea and the fediverse should do it too? IT IS! (And as I also said, it's actually fully possible for the fediverse to do, more on that later.)

But the reality is, it's still *centralized*

Christine Lemmer-Webber replied to Christine

In every meaningful way from a power dynamics perspective *EXCEPT* the category of "credible exit" (which I am saying and agreeing is a good idea!) Bluesky is centralized.

MAYBE another big corporation could come along and host all this stuff but that's adding a Bing to our Google

Christine Lemmer-Webber replied to Christine

Yes, you can host your own PDS. You can also host your own blog. But try hosting your own PDS and NOT hosting a relay or AppView and you can't do much.

Blogs are decentralized, Google is not.
PDS'es are decentralized, Bluesky is not.

Christine Lemmer-Webber replied to Christine

We're getting to the point where we get to why I'm so damn frustrated about this and have been biting my tongue until it nearly comes detached from my mouth: users THINK Bluesky is decentralized because they're TOLD Bluesky is decentralized

AUGH! *That's* what drives me nuts.

Dr Kim Foale replied to Christine

@cwebber if theres one frustration i have trying to mature a tech thing the last few years its that "maybe this could work in the future" seems to be a much much bigger draw for people than "this is actually working now and we can use it if only we do X". it suckssss. like imagine if mastodon was only mastodon.social lol

Christine Lemmer-Webber replied to Christine

Here's an example of this problem in action

fry69: "The working search box was the second thing that impressed me on Bluesky, I thought that was not possible with a decentralized model"

Sorry fry sixty-nine I regret to inform you the reason search works so well is that it's centralized! THAT'S WHY

Christine Lemmer-Webber replied to Christine

So hold on, let me set some terms for "decentralization" and "federation" that I think are reasonable.

> Decentralization: the result of a system that diffuses power throughout its structure, so that no node holds particular power at the center.

Pretty reasonable. Do you agree? I hope so!

Christine Lemmer-Webber replied to Christine

Okay how about "federation" now because this is a *technical term* that the *fediverse has established* and I'm kinda PO'ed about the goalposts being moved on this one.

A lot of people coming to Bluesky have never heard of "federation" before in a social network so listen up this is important!

Christine Lemmer-Webber replied to Christine

Here's my definition of federation:

> Federation: a technical approach to communication architecture which achieves decentralization by many independent nodes cooperating and communicating to be a unified whole, with no node holding more power than the responsibility or communication of its parts.

Christine Lemmer-Webber replied to Christine

Now historically, federation has been achieved on the fediverse via "message passing". Actually, this is to the degree where I just always associated message passing with federation, but really, federation is about the distribution of power, creating an abstract whole in a sea of autonomy.

Christine Lemmer-Webber replied to Christine

Maybe there is another way to achieve federation, but it's about the power dynamics. It's a technical immersion of power dynamics, the flow and interchange of cooperation between many parts.

So you may say, well, doesn't ATProto have that? After all, messages flow through the different parts!

Christine Lemmer-Webber replied to Christine

ActivityPub, as it turns out, follows the actor model of computation. Okay, many people implementing the fediverse don't know about the actor model aspect of ActivityPub but I am here to tell YOU, dear reader, that it is an important thing, not a detail

Christine Lemmer-Webber replied to Christine

I'll take one more note about federation which is that often time the message passing mechanism of the fediverse is often called "federation", but theoretically another mechanism could exist, but I'm actually not so sure of that.

There's a reason the actor model and the lambda calculus are undying

Christine Lemmer-Webber replied to Christine

Oh god Christine said "the lambda calculus" did you know she's into lisp and functional programming, what's she going to talk about next monads?!?!

I am not going to talk about monads. Not TODAY

But we do need to get a better architectural idea of how these systems work because it matters a lot!

Edward L Platt replied to Christine

@cwebber I want to be able to speak intelligently enough on the subject, but I only learned enough about Bluesky/ATProto to know that I wasn't interested in using it. Do you think it's worth understanding to be able to explain to people? And/or is there a good brief explainer somewhere?

Edward L Platt replied to Christine

@cwebber I have kind of an axe to grind about "decentralized" systems that are really centralized organizations using some decentralized tech. People look at the protocols and cables to evaluate centralization, but what really matters are the wider trust relationships that are a layer even below those.

Anders Thoresson replied to Christine

@cwebber Dropping in mid-thread just to thank you for it! Helps me understand things. :)

Les Orchard replied to Christine

@cwebber An analogy I've used with some folks is to imagine blogs you can only read through Google Reader. And if Google Reader shuts down, you can't read those blogs any more. But that'll never happen right?

(which, of course, I see you've covered as I read further through your thread! πŸ˜… )

ionizedGirl replied to Christine

@cwebber if content addressed storage is considered a new idea then I'm done. I quit

Peter replied to Christine

@cwebber

Whether you're finished or not, this thread is great, well done.

But this particular post is SO MUCH BETTER & more informative than 2/3 of what I've seen anywhere online in the last month I had no choice but to single it out.

πŸ‘

danicotillas \ D4ns replied to Christine

@cwebber Have you already publish It? I Guess this is the one Where you explain if it'll be posible a federation between AT & ActivityPub

Tom Casavant replied to Christine

@cwebber if you could convert this thread to TTS narration and attach it to some subway surfers footage I'll be set

Kye Fox replied to Christine

@cwebber FWIW, there are over 1000 independent PDSes right now, and the number seems to grow at about 400-500 a month.

The practical effect is different since the means to control that data beyond exporting without funky command line tools rests with the AppView, which is still extremely centralized.

edit: a list + count github.com/mary-ext/atproto-sc

em replied to Christine

@cwebber worth noting that they do have their moderation bot partially open sourced, including an (example?) image scanning integration
but it looks like every appview would need to run their own instance, it isn’t set up to be shared like labelers
