Thanks for pointing this out. Looking closer I see that this is not a publication I want to send traffic to, for a variety of reasons.
I edited the post to link to MIT instead, and added a note in the post body explaining.

- Comment on How decentralized Bluesky is compared to the Fediverse. 1 week ago:
with BlueSky I’d have to account for the data volume of all users on the platform as a whole, bringing the data volume way up to tens of terabytes
I think this is a common misconception based on some critics’ incorrect assumptions and back-of-the-envelope math. See the atproto overview for the different components involved, and then this post (from a BlueSky employee) “A Full-Network Relay for $34 a Month” for some numbers.
If I understand correctly, to run a “full nework relay” does mean to consume all of the text posts from all known servers, but not necessarily all of the media, and not necessarily to keep data you aren’t interested in for any long period of time.
Also, you can run your own PDS and/or App Views without running your own relay at all. And, you can also use multiple other people’s relays.
Disclaimer: I’m not an atproto expert, and I haven’t set any of this up myself.

The blog post also says this:
There is one other thing which Bluesky gets right, and which the present-day fediverse does not. This is that Bluesky uses content-addressed content, so that content can survive if a node goes down. In this way (well, also allegedly with identity, but I will critique that part because it has several problems), Bluesky achieves its “credible exit” (Bluesky’s own term, by the way) in that the main node or individual hosts could go down, posts can continue to be referenced. This is possible to also do on the fediverse, but is not done presently; today, a fediverse user has to worry a lot about a node going down. indeed I intentionally fought for and left open the possibility within ActivityPub of adding content-addressed posts, and several years ago I wrote a demo of how to combine content addressing with ActivityPub. But nonetheless, even though such a thing is spec-compatible with ActivityPub, content-addressing is not done today on ActivityPub, and is done on Bluesky.
My comment should have been clearer; what I meant when i said it is more “decentralized architecturally” I was referring to the data model part of the architecture as opposed to the physical server infrastructure currently operating it. The latter is obviously quite centralized still, but the former is designed for resilience against nodes unexpectedly (and permanently) failing.

ok, but, does ActivityPub have portable identity and/or content addressability yet, so that when some of those servers (which are often hobbyist-run and/or tenuously funded) inevitably cease operating their users can continue on a different server? 👀
It’s a rhetorical question, and the answer is no.
otoh, atproto’s PLC DID method is also not really decentralized… but at least the rest of their system is actually substantially more decentralized architecturally than AP is.
To anyone interested in reading a very informative in-depth discussion of this topic, I recommend the blog post How decentralized is Bluesky really? by ActivityPub co-author Christine Lemmer-Webber (followed by this and this).

i looked into other services with did got an llm to put those ideas in the required format for the issue. Can you please point out the hallucinations in the issue so i can go and fix them
No. Asking other people to read (and now also to correct!) your LLM slop is extremely inconsiderate. Please don’t do that again.

- Comment on Terrible liquid coils 4 weeks ago:
looking closer I see the earliest archive.org snapshot of this URL (from Feb 27, 2020, the day it was published) also says 1857 so it seems like the transposition to 1847 must have happened somewhere else - and yet the attribution to SciAm (external to the screenshot) was somehow preserved. @nymnympseudonym@lemmy.world can you shed any light on this mystery? where did you obtain this image (and know to attribute it to SciAm)?
- Comment on Terrible liquid coils 4 weeks ago:
apparently in 1857 “I have been informed by a European acquaintance” was sufficient sourcing for something to be published in Scientific American :)
somewhat relatedly, it’s 2025 now so you can actually link to a thing instead of just posting a screenshot of it: scientificamerican.com/…/that-giant-sucking-sound…
i wonder why this screenshot (and OP’s text which includes the fact that this comes from scientific american, which is not included in the screenshot) both say 1847 while the text on the SciAm website says it’s actually from 1857 🤔

- Comment on Could I just create my own drive format? 4 weeks ago:
NTFS, fat32, exfat, could I theoretically create my own filesystem?
Yes. There are many different file systems and with a bit of work you can absolutely create your own. Making one that is reliable and performs well, and/or is something you can actually use for the disk that you boot from, is a lot of work and generally involves low-level kernel programming - not exactly a beginner’s programming project.
However, you can also more easily play with implementing filesystems in a high-level language using FUSE.
If so would my computer even be able to work with most files or connect to other devices?
Your computer can use many different filesystems at the same time. You can also store a filesystem in a file on another filesystem, rather than dedicating a partition of a physical disk to it. So, yes, you can use a filesystem of your own design at the same time you are using other storage devices formatted with more common filesystems.

these two snails mated with each other instead, producing 170 right-coiled snails. One of the left-coiled snails later mated with Jeremy, producing 56 offspring, all of which also had right-coiling shells.
they also omitted this crucial detail:
Jeremy was named after the left-wing British Labour politician Jeremy Corbyn, on account of it being a “lefty” snail, but also due to Corbyn’s reported love of gardening.
