  • 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




  • I live 2000km from Chernobyl

    Chernobyl is not comparable to a nuclear bomb. Chernobyl is a reactor, made to release a steadily amount of radiations for years to make electricity.

    Chernobyl irradiated a large area because the graphite that was located in the reactor core has burned, and the fumes have been carried by the wind, taking a lot of high-level activity nuclear waste hundred or thousands of kilometers away.

    A bomb is way smaller than a reactor, and is designed to release most of its energy instantly to make the biggest explosion possible. That means a short burst of radioactivity very high level of radioactivity, with a very small half-life.

    A few days after a bomb explodes, most of the radiations would have depleted.









  • Macron is turbo economical liberalism, and he does everything he can to not be affiliated with the left.

    He even dissolved the Assemblée Nationale (our Parliament), and when a left-wing coalition came out on top, which should have secured them the prime minister’s seat, Macron delayed the appointment for months trying to buy time for the right to secure an agreement with the far right, and ended up choosing a prime minister from a right-wing party who did had only 7% of votes.
