    It makes it more dangerous : the sting is attach to the venom bag, so the venom bag gets to empty itself whole if it stays. Evolution would have chosen the survival of the hive, not the survival of the bee.

    One thing is weird though : you can extract the sting of a wasp with a pincer. The wasp will live through it. Why do the bee dies when it loses it’s sting and not the wasp?





  • Starfleet is not anarchist. There are admirals. There are federation laws and judges (1st directive, in strange new worlds, laws against eugenics). Those laws and positions of power are decided on a federal level. How do you do that in an anarchist organization?

    I fail to see how a federation can not be a representative government (because different worlds have different political systems, representative democracy is the only one that can make them all on an equal footing).


  • I certainly don’t know much about anarchism, but different planets in the federation can and do have different kinds societies.

    If we consider the vulcan in brace new world for example, their society seems very much aristocratic for example, where influence gives authority and power. I doubt the klingon are anarchists either. And in lower deck, the orions have a monarchy.

    The federation is the government of the collection of planets, but each planet still has its own government and culture.

    Ha ! Turns out I’m right after all : radioactivation can happen with all type of radiations. But neutron activation is the lowest energy one.

    You are right that it’s probably a contamination for the book though, and not directly an activation (although carbon can be activated and will be found in the book).

    I know quite a bit about radioactivity thanks to my studies. I was sure all radiations could activate something, but it turns out I was wrong apparently because I can’t find anything but neutron activation.

    I’m pretty sure alpha, beta and gamma rays can stick to a particle, often bringing it in an unstable state that will force it to release something to get into a stable state. That’s particle physics. And that’s why we call them ionising radiations : because they turn atoms into ions. But my memories are definitely fuzzy, and it was not were I was the best.

    Those radiations may only activate for a too short time to be useful maybe? I don’t know.

    Marie Curie studied radioactivity with pure and very active materials with no protection. The radioactivity of the notebook is indirect radioactivity, that is material that becomes radioactive after being exposed to powerful ionizing radiations. It must be noted that the notebook may not be deadly radioactive. And if it will be for 1500 years, it won’t be deadly for 1500 years. For reference, bananas tend to be radioactive too. And you are exposed to ionizing radiations when you take the plane.

    Chernobyl had two reactors burn iirc. Most of the radioactive material was in the reactor, but the fire made smoke out of radioactive materials. The quantity of smoke, in kg, that go out was significant, but it got diluted in the atmosphere and spread. Which means there wasn’t so much dust, in mass, that got in any one place. The dust is also not only uranium, but a combination of uranium and materials that were contaminated like the notebook. With the rain, the dust was washed and distributed more, and with the time, materials become less and less radioactive.

    Both the book and chernobyl are not dangerously radioactive. But because of the nature of radioactivity, care must always be taken.


  • I must be clear that the problem is not that it rakes time to do the things if you have the right recipe to do them. It takes time to find it when you make a mistake.

    The good way is simple: you need a system that’s well updated, so debian stable is not ideal and that was my first mistake. You need to use Proton on steam, or heroic game launcher for gog. And that’s it.

    The setup for these things is straightforward, simply follow a guide for your OS.

    Things got better and better in the last 2 years, and they’re still improving. I would argue that today Windows is not better. People learned how to install graphic drivers on windows, and any setup on Linux now is not harder than that.


  • Windows forced me to update to a version that has advertisement in it. It has built in network calls in the start menu. I would have to pay a licence and make an account, something I avoided for years. Sharing file on a private network is insanely hard to do and very buggy.

    Now I’m not a Windows admin, but I’m a Linux admin, so there are many, many things I know how to do on Linux and not on Windows.

    This made me realize that there is a bias: when something doesn’t work on windows, the something doesn’t work, or you only need to find how to hack it to work. But when something doesn’t work on Linux, it’s Linux that doesn’t work. That’s a double standard. The same kind of work or problems on Windows is ignored.

    There are so many things today to help people use Windows, like classes, professionals, help desk, it’s everywhere, for everyone, yet it’s somehow considered easy to use windows. BTW any organisation that made the move did saw it happen. I mean that many organisations moved to Linux and gave the support and formation for it to work, and it worked.
