  • Interestingly, whilst Wikipedia does say that, the language in RFC 1591 (Domain Name System Structure and Delegation) only says:

    There are a set of what are called “top-level domain names” (TLDs). These are the generic TLDs (EDU, COM, NET, ORG, GOV, MIL, and INT), and the two letter country codes from ISO-3166.

    Likewise, in ICANN’s PRINCIPLES FOR THE DELEGATION AND ADMINISTRATION OF COUNTRY CODE TOP LEVEL DOMAINS, they say:

    ‘Country code top level domain’ or ‘ccTLD’ means a domain in the top level of the global domain name system assigned according to the two-letter codes in the ISO 3166-1 standard

    In neither case do they actually limit two letter TLDs to being country codes, they only state that all country codes in ISO 3166-1 are ccTLDs. In the RFC, the author does suggest it is unlikely that any other TLDs will be assigned, but this has obviously been superseded with the advent of gTLDs. Thus I still consider it likely that the .io TLD will simply transition to being a commercial one, rather than a country one.

    Having said all that, it’s entirely possible I’ve missed some more recent rule that tightens this up and only allows two letter domains from ISO 3166-1. If I have I’d be glad of a pointer to it.



  • It’ll get eliminated as a country code, yes, but that leaves it available as a generic TLD. Seen as it will be available and is obviously lucrative, someone will register it and, presumably allow domains to be registered under it. Off the top of my head, I think it costs $10,000 and you have to show you have the infrastructure to support the TLD you register, so an existing registrar is the most likely. That figure is probably out of date, it’s been many years since I checked it, but the infrastructure requirement is the more costly part anyway.



  • I agree that them having users’ phone numbers isn’t ideal. There are other identifiers they could use that would work just as well. However, both the client and server are open source, so you can build, at least the client, yourself. If you can content yourself that it does not leak your ID when sending messages, then you don’t need to trust the server as it does not have the information to build a graph of your contacts. Sealed sender seems to have been announced in 2018, so it’s had time to be tested.

    Don’t get me wrong, the fact they require a phone number at all is a huge concern, and the reason I don’t really use it much, but the concern you initially stated was addressed years ago and you can build the client yourself to validate that.


  • You’re correct that if you use the system the way it used to work they can trivially build that connection, but (and I know this is a big assumption) if it does now work the way they say it does, they do not have the information to do that any more as the client doesn’t actually authenticate to the server to send a message. Yes, with some network tracing they could probably still work out that you’re the same client that did login to read messages, and that’s a certainly a concern. I would prefer to see a messaging app that uses cryptographic keys as the only identifiers, and uses different keys for different contact pairs, but given their general architecture it seems they’ve tried to deal with the issue.

    Assuming that you want to use a publicly accessible messaging app, do you have any ideas about how it should be architected? The biggest issue I see is that the client runs on your phone, and unless you’ve compiled it yourself, you can’t know what it’s actually doing.




  • Whilst I absolutely agree it’s correct to be skeptical about it, the ‘sealed sender’ process means they don’t actually know which account sent the message, just which account it should be delivered to. Your client doesn’t even authenticate to send the message.

    Now, I’m just going on what they’ve published on the system, so either I could be completely wrong, or they could be being misleading, but it does look like they’ve tried to address the very issue you’ve been pointing out. Obviously it’d be better if they didn’t have your phone number at all, but this does seem to decouple it in a way that means they can’t build a connection graph.




  • It’s a non-starter for me because I sync my notes, and sometimes a subset of my notes, to multiple devices and multiple programs. For instance, I might use Obsidian, Vim and tasks.md to access the same repository, with all the documents synced between my desktop and server, and a subset synced to my phone. I also have various scripts to capture data from other sources and write it out as markdown files. Trying to sync all of this to a database that is then further synced around seems overly complicated to say the least, and would basically just be using Trillium as a file store, which I’ve already got.

    I’ve also be burnt by various export/import systems either losing information or storing it in a incompatible way.






  • While I agree with most people here that finding a keyboard and screen would be the easiest option, you do have a couple of other options:

    • Use a preseed file A preseed lets the installer run completely automatically, without user intervention. Get it to install a basic system with SSH and take it from there. You’ll want to test the install in a VM, where you can see what’s going on before letting it run on the real server. More information here: https://wiki.debian.org/DebianInstaller/Preseed

    • Boot from a live image with SSH Take a look at https://wiki.debian.org/LiveCD in particular ‘Debian Live’. It looks like ssh is included, but you’d want to check the service comes up on boot. You can then SSH to the machine and install to the harddrive that way. Again, test on a VM until you know you have the image working, and know how to run the install, then write it to a USB key and boot the tsrget server from that.

    This all assumes the target server has USB or CD at the top of its boot order. If it doesn’t you’ll have to change that first, either with a keyboard and screen, or via a remote management interface sych as IPMI.


  • It’s the same problem with a drive like this, or any long term archive, you either store the data unencrypted and rely on physical security, or make sure you store the encryption key and algorithm for the same length of time, in which case you still need the physical security to protect that instead. In both cases you need to make sure you preserve a means to read the data back and details of the format its in so you can actually use it later.

    Paper is actually a pretty good way of storing a moderate amount of data long term. Stored correctly it’s unlikely to physically degrade, the data is unlikely to suffer bitrot and it can be read back by anything that can make an image in the visible spectrum. That means you can read it, or take a photo and use OCR to convert it into whatever format is current when the data is needed.
