    The article does not explain the primary design purpose of a VPN – providing an encrypted tunnel into or between two private subnets.

    For example, your home subnet is typically all 192.168.nnn.nnn addresses – a class of addresses which the wider internet does not route, and which your router/modem does not allow the wider internet to access unless explicitly permitted.

    Say you have a NAS on your home network, and you want to access it from your laptop while at a cafe; you could set up a VPN between your laptop and your home router, and it can make your home network appear as your local network to your laptop, giving you access to your NAS.

    Or between two office locations of a business – their database servers, accounting systems, printers, etc can all be freely accessible between offices without being exposed to the wider internet.




  • I mean ntfy’s primary purpose is not dependent on UnifiedPush – all UP functionality could be removed and ntfy would still work as intended.

    Ntfy server knows how to be a UP gateway, and relays those messages to the ntfy app, which knows how to be a UP distributor.

    As far as I understand it, a client app using UP to recieve push notifications does perform a registration step with the UP gateway (via the distributor app which communicates with the gateway via its own transport), which sets up and responds with the api endpoint details, which the client app relays to its servers, which can then send UP notifications via the specified gateway.

    You have to trust the servers with your metadata, and that the servers have their inter-server communication locked down, but at least you can choose/operate servers.

    Some clients are a bit flaky with their e2e encryption defaults or from a UI perspective it is easy to send an unencrypted message (in a new chat for example) before noticing that was how it was set.

    There are a few XEPs the server needs which enable things like OMEMO, efficient mobile data/battery use, offline and multiple device deliverability, file transfers, etc. Audio/video calling has various requirements as I think xmpp only facilitates the setup of the call.

    XMPP lacks good clients and suffers from fragmentation of protocol standards implementation

    • For Android: Conversations is excellent, also on F-Droid if you don’t want to use the Google store.
    • For iOS/MacOS: Siskin or iOS/MacOS: Monal.
    • For Linux/Windows: Gajim or Linux: Dino.

    “Protocol fragmentation” is not a valid complaint about XMPP – it’s like complaining that ActivityPub is fragmented; but that’s not a problem: you use the services (Mastodon, Lemmy, Kbin, etc) built with it which suit your needs, mostly interacting with that sector of the federation (eg, Lemmy+Kbin), but get a little interoperability with other sectors as a bonus (eg, Lemmy+Mastodon).


  • When human shields are used, the attacking party must take into account the risk to civilians. 191 Indiscriminate or disproportionate harm to civilians remains unlawful and the civilian population can never be targeted.

    So, from this I understand that every time Israel makes an accusation of “human shields”, it’s a direct admission of guilt of war crimes in that they are knowingly targeting civilians.
