aircraft for example

due to DO-178C requirements, Linux can’t be used there… yet.

What you want is not an “uncensored” server, but rather a server that is moderated in a way that you find acceptable.

There is no such thing as an “uncensored/open” server. Or, when there is, it can’t last long. Every open server needs to delete some things, because if they don’t, their disk will soon be full of spam and CSAM and then the server will go away. Some servers claiming to be “uncensored” might allow nearly everything besides those two categories, but they tend to quickly become nazi bars.

Sorry i don’t have any specific suggestion, but of the 61 servers listed here hopefully there is one with a moderation policy that is to your liking.

The server isn’t exposed to the internet. It’s a local IMAP server.

if it is processing emails that originate from the internet, it is exposed to the internet

security updates are for cowards, amirite? 😂

seriously though, Debian 7 stopped receiving security updates a couple of years prior to the last time you rebooted, and there have been a lot of exploitable vulnerabilities fixed between then and now. do your family a favor and replace that mailserver!

From the 2006 modification times, i wonder: did you actually start off with a 3.1 (sarge) install and upgrade it to 7 (wheezy) and then stopped upgrading at some point? if so, personally i would be tempted to try continuing to upgrade it all the way to bookworm, just to marvel at debian stable’s stability… but only after moving its services to a fresh system :)

i’m not aware of anybody who allows public signups and is interoperating with bsky.app yet (besides Bridgy Fed which will create an ATP identity for your ActivityPub identity), but I’m pretty sure it is possible because I follow people there who appear to be doing it for themselves.

see also my reply to you in another thread.

Very interesting, thanks! Is it possible for people to register on that relay?

(if I understand correctly) you don’t register on a relay, you register on a PDS (which you can easily self-host on a small computer at home). But, to register with a PDS, you need a DID, and to interoperate with the rest of bluesky it needs to be using one of their two currently-supported DID methods: either did:web or did:plc. The former is a thing which you can create using a domain you control, which gives you an identity that you lose control of when you lose control of that domain. The latter is the actually-centralized “placeholder” DID method implemented by an append-only log operated by BlueSky PBC, which is what most people are actually using. I’m not sure if/how you can create a did:plc without first creating an account on a bsky.app PDS, but you can migrate it to your own PDS after creating one there. or, you can use did:web and rely on your domain name registration instead of their centralized log.

• minimal AppView example
• “self-hosting entire bluesky” with docker-compose (including AppView, apparently)

as i wrote in another thread:

Content addressability is absolutely essential for building something that will last, and BlueSky gets that right. Decoupling the many responsibilities which an ActivityPub instance operator has (especially for identity) is also essential, i think, and while BlueSky’s identity solution is less than ideal it’s much better than ActivityPub and I expect it to improve.

If you’re interested in the topic you probably want to also read the followup post from the same author (after reading the reply linked there from someone on the BlueSky team).

Christine’s analysis is by far the best I’ve read on the topic, but I think she is too dismissive of the possibility that people will actually build things using ATP in a manner more like ActivityPub (where there doesn’t need to be a global view). It’s also possible/likely that ActivityPub will eventually evolve to adopt content addressability (Christine actually built a proof-of-concept of doing that years ago, linked in her blog post, but there doesn’t appear to be any recent progress in that direction), and decouple identity from responsibility for data availability, and adopt something like BlueSky’s composable moderation.

Given their respective advantages over the other, i’m pretty sure that both ATP and AP will make changes which make them more like the other in the coming years.

in what sense

Reading through it, I’m not seeing much in favor of ATP

See the “BlueSky’s strengths” section, particularly the last paragraph of it. Content addressability is absolutely essential for building something that will last, and BlueSky gets that right. Decoupling the many responsibilities which an ActivityPub instance operator has (especially for identity) is also essential, i think, and while BlueSky’s identity solution is less than ideal it’s much better than ActivityPub and I expect it to improve.

In my opinion, yes, the why does in fact matter. This blog post i’ve linked in other comments in this thread is by one of the authors of the ActivityPub spec. If you care enough to comment about it i recommend reading her analysis of what AT Proto gets right and wrong in comparison with ActivityPub.

but you have to question why they’re choosing to reinvent the wheel

you don’t have to wonder why if you take the time to read about why; see the links in my other comments in this thread if you’re curious.

Is there any instance other than Bluesky where people can register?

There aren’t “instances” in the ActivityPub sense, where “instance” means single point of failure you’re married to (its name is literally part of your identity) which is simultaneously responsible for keeping your data available and curating your view of the rest of the network; AT Protocol decomposes these responsibilities so that they can be delegated independently to different operators.

See https://docs.bsky.app/docs/advanced-guides/federation-architecture and https://dustycloud.org/blog/how-decentralized-is-bluesky/ for details.

There are many people running their own Personal Data Servers, AppViews, Labelers, and Feed Generators, but I’m not aware of anybody else running a large-scale Relay yet (which is one of the things this new foundation says they are planning to work on). I’m also not sure if you can actually create a did:plc using a self-hosted AppView or if maybe you need to use did:web to create a new identity without using their AppView currently.

They mention ActivityPub in a few places, such as this blog post.

But I’d recommend https://dustycloud.org/blog/how-decentralized-is-bluesky/ instead, which is the best discussion I’ve seen so far of the pros and cons of each of the two approaches.

have you read about why they didn’t?

I asked this question the other day if I could somehow input my handwritten notes into programs like Trilium (or logseq whatever) and memos. OCR/HCR seems to far behind still so I am unsure.

I just left this comment on your post.

Via the pine64 blog update about their e-ink tablet TIL about inkput (using OnlineHTR) which appears to be a step in the right direction.

there is no provider on the planet that can freeze state of RAM in a way that would be useful for this

You are very mistaken, this is a well-supported feature in most modern virtualization environments.

Here are XenServer docs for it. And here is VMWare’s “high-frequency” snapshots page.

Sometimes, law enforcement authorities only need to contact cloud provider A when they have a warrant for (or, perhaps, no warrant but a mere request for) data about some user C who is indirectly using A via some cloud-hosted online service B.

A(mazon) will dutifully deliver to the authorities snapshots of all of B’s VMs, and then it is up to them if they limit themselves to looking for data about C… while the staff of company B can honestly say they have not received any requests from law enforcement. (sorry my best source on this at the moment is sadly trust me bro; I’ve heard from an AWS employee that the above scenario really actually does happen.)

Relatedly, there was a company was selling a cloud(🤡)-based product called “Little Printer” from 2012 to 2014; after their backend predictably shut down, some fans of it recreated it as https://tinyprinter.club/ and later https://nordprojects.co/projects/littleprinters/

somehow input my handwritten notes

I’ve heard the reMarkable e-ink tablet’s cloud service has good-enough-to-be-usable handwriting recognition, but sadly I haven’t heard of anything free/libre and/or offline that is.
