    I don’t use Mastodon, but I don’t know if it’s possible to do this particular combination:

    without owning a domain

    users on the local server should still be able to follow accounts on other Mastodon servers

    Like, a client that supports having accounts on multiple Mastodon servers would work. Then they have a local account, and they have an unrelated account elsewhere on another Mastodon server and follow people using that, so that the “following” has nothing to do with your local server.

    But if you want federated behavior, where a user connects to your server and has their account there tell the local Mastodon server to pull down posts from another users somewhere out on another Mastodon server, you might need to have a certificate on your server that other servers recognize as valid, which in practice would mean one signed by a public CA.

    I don’t know for certain whether this is actually necessary, but I could believe that it is.

    I wonder if they could use it as a testbed for launching hypersonic ramjet-driven weapons that are optimized for high speed to the point that they can’t function below very high speeds. Wasn’t designed for that, but it’d be an application where survivability in enemy space wouldn’t matter, they wouldn’t need many, and speed would be important. We are doing work on hypersonic weapons.

    searches

    It sounds like there were plans for a plane that filled something along the lines of that role:

    https://en.wikipedia.org/wiki/Lockheed_Martin_SR-72

    The Lockheed Martin SR-72, commonly referred to as “Son of Blackbird”,[1] is an American hypersonic concept intended for intelligence, surveillance, and reconnaissance (ISR). It was proposed privately in 2013 by Lockheed Martin as a successor to the retired Lockheed SR-71 Blackbird.

    In November 2018, Lockheed Martin reported that a prototype of the SR-72 was scheduled to fly by 2025 and would be equipped to launch hypersonic missiles.[26] As of 2026 no such prototype has been launched.[27] The SR-72 could enter service in the 2030s.[28]

    In September 2026, Jared Isaacman, Administrator of NASA, during his presentation, “A New Era for NASA and American Space Exploration” at the All-In Summit he mentioned rebuilding NASA’s X-Plane portfolio. On the slideshow, it shows a image of a unknown plane similar to the SR-71 Blackbird.[29][30]

    EDIT: Scramjets apparently have a floor speed that’s higher than the SR-71’s ceiling speed, so I don’t think an SR-71 could be used to get a scramjet-based hypersonic weapon up to operational speed; it’d need to be a ramjet.

    https://en.wikipedia.org/wiki/Scramjet

    A scramjet (supersonic combustion ramjet) is a variant of a ramjet airbreathing jet engine in which combustion takes place in supersonic airflow.

    Because they can only operate in hypersonic airflow (>Mach 5), the aircraft to which they are attached must attain a hypersonic airspeed before the scramjet can be enabled.

    EDIT2: It sounds like Mach 5 isn’t the scramjet floor (the article is probably just giving the floor for “hypersonic”) but it sounds like past scramjets still had to be boosted to close to that, a higher speed than the SR-71 could manage:

    The X-51A was carried aboard a B-52, accelerated to Mach 4.5 via a solid rocket booster, and then ignited the Pratt & Whitney Rocketdyne scramjet engine to reach Mach 5 at 70,000 feet (21,000 m).

    My impression—I don’t use it myself and my few experiences touching it have not impressed me—is that the major selling point is that it provided several different forms of communication that gamers wanted to use in a single package. Like, instant messaging, VoIP, video calls, chat, etc.

    You could set up all of these individually, but this was free and all-in-one, is managed, and it didn’t require much technical expertise to use. Any user with an account has access to all the components.

    And it didn’t cost anything to set up.

    If I were going to set up, say, a VoIP server, I’d probably use, oh, Mumble. I’d get my own VPS for it, which would cost something. I’d only have VoIP at the end of that. If I wanted to use say, text-based communication or have some mechanism for sharing files, I’d have to go cobble something together from other components.

    Every single EV is a privacy nightmare.

    I’d love a dumb EV, but there is none.

    Slate Truck. I mean, the base model is also stripped of basically every luxury that’s been on a vehicle since the 1980s to bring the base price down. It does have airbags. There are no privacy issues because there is no entertainment computer, no GPS radio, no cell radio. Just a mount point for you to provide your own computer.

    https://en.wikipedia.org/wiki/Slate_(vehicle)

    Designed around a starting price of US$24,950, the vehicle uses a simplified design with fewer parts and omits features such as an infotainment system, speakers, and power windows. All vehicles are to be produced with an unpainted gray plastic exterior and support customization through accessories and vinyl wraps.

    The Slate’s base configuration, called the “Blank Slate”, will not include an infotainment system, speakers, or power windows. All units will be produced with the same unpainted gray polypropylene exterior, with vinyl wraps as the only offered way to change the exterior color.[13] A smartphone mount will be standard, and a tablet mount optional. The Blank Slate configuration will have fabric armrests and physical climate control knobs. The company plans to offer a large number of accessories for professional or DIY installation.[14]

    There isn’t much there to have privacy implications. I haven’t looked at the (now government-mandated on new cars) tire flat detection system, whether it uses radio to talk to the wheels. Some people are concerned that vehicles that use radio TPSes broadcast a unique ID, and that that facilities ALPR-like logging of vehicles, though I’d guess that for most, that’s a pretty secondary concern to things like manufacturers harvesting data via phone-home.

    That being said, it’s got a shorter range than, say, a Tesla Model 3, which could be an issue for some users.

    EDIT: And just to be clear, since OP’s article is talking about the UK, I have no idea whether it’s available in the UK. Serial production should be starting in the US shortly, late this year.
