  • You’re talking about a 70’s prototype, but that does not mean it would need a kerosene turbine if it was made nowadays. Actually, the Aérotrain S44 used a linear electric motor.

    A train brakes by blocking the wheels on two relatively small rails, and the wheels can lose traction.

    An aerotrain reverses its propulsion, using it as a brake. No slippage possible here.

    It can also bite the rail, having a way bigger braking surface, as well as having an interface dedicated to braking directly on the rail instead of a brake on a wheel on a rail.

    And in emergencies, you can even stop the suspension and let the aerotrain rest directly on the rail to brake. That’s a bit brutal and causes damages (at least back in the 70’s), but that stops the Aérotrain quite fast and is way better than derailing or hitting something.








  • You can look up for:

    • Setting up max authentication attemps per connection -> slows up a lot brute force attacks. If your password is strong enough, that’s already a big step to secure your server.
    • Generate SSH Keys and disable password authentication -> do this only if you’re connecting through the same devices, because you won’t be able to connect from any device that has not being set up. Personally I don’t use this because I want to be able to access my server even if I’m not home and without my laptop
    • Set up Crowdsec -> it’s a local service which scans logs and will block access to any suspicious IPs. It also relies on a crowdsourced list of IPs that are identified as threat and will preventively block them

    While true, how is that any different to the arguments that were used for TV?

    Television is bad because it is a passive activity, but it is less harmful than the continuous ingestion of micro-videos. But I don’t see what it has to do here.

    Additionally, Lemmy is a social network in the same way that Reddit is. Is this not also dangerous?

    What’s the connection? I didn’t mention Reddit.

    As has been the recommendation for practically everything for the four decades I’ve been on this earth, moderation is key. Instead of hating new media, either regulate it (if the evidence is truly that great) or treat it with healthy moderation.

    This would be to ignore the particularly addictive nature of this kind of content. It would be like comparing apples to Snickers: both are sweet, yes, but one is much more problematic.

    Let’s be blunt here. Most of the people in this thread aren’t worried about health

    That could be a point, but I’m pretty sure that if you ask anybody, the main reason given would be that it makes you stupid. But I can agree that this opinion would not necessarily be based on anything other than the eternal contempt for novelty as video games or manga were, for example, before they became popular.

    ITT: People in their mid-twenties or later, who feel superior to those that like one form of media over their preferred media.

    You’re just waving away an important fact, which is that shorts and their equivalents are notoriously known for killing attention spans and disrupting the management of dopamine in the brain, causing depression in particular.

    We are no longer simply in the traditional custom of the elderly who despise the activities of the younger generations, we are talking about health.
