  • Many encryption algorithms rely on the assumption that the factorizations of numbers in prime numbers has an exponential cost and not a polynomial cost (I.e. is a NP problem and not P, and we don’t know if P != NP although many would bet on it). Whether there are infinite prime numbers or not is really irrelevant in the context you are mentioning, because encryption relies on factorizing finite numbers of relatively fixed sizes.

    The problem is that for big numbers like n=p*q (where p and q are both prime) it’s expensive to recover p and q given n.

    Note that actually more modern ciphers don’t rely on this (like elliptic curve crypto).

    Encrypted DNS doesn’t solve everything. Handshake for TLS sessions is still in clear, you can usually see the SNI, and since we are talking about Wireless, usually this data is available to anybody who is in the vicinity, not just the network owner. This already means that you can see what sites someone is visiting, more or less. TLS 1.3 can mitigate some of this (for those who implement ESNI, but you don’t know that beforehand). Also TLS works until the user is not accepting invalid certificates prompts (HSTS doesn’t work for everything) and there are still tons of HTTP-based redirect (check mailing newsletters and see how many first send you to an HTTP site, for example) that can be used for MiTM attacks.

    A VPN moves the trust to a single provider that you can choose, which is much better than trusting every single WiFi network you can attach to and the people connected to it, I would say.

    Also if you pay for the VPN (I pay Proton), it’s not true that the company business is based on user data, they are based on subscriptions.





  • Most of Italian recipes are very simple. The focus usually is on quality on the ingredients and if they are good, a pizza with just mozzarella and tomatoes is already delicious. That said, even in Italy there are plenty of types of pizzas, but most of them don’t have 20 ingredients, I suppose the point is that you actually want to taste what you eat, which is not the case when you mix many different things. There is a very messy and rich pizza (capricciosa) with a lot of toppings though (more than one obviously, but this is the most common).

    Personally I am a margherita person, simple and boring is perfect, as long as it tastes great.

    P.s. Giuseppe :)




  • For what is worth, that’s not how (most?) Italians think about pizza. It’s not a “container” in which you put a bunch of things, but each pizza type is basically a separate dish.

    I personally don’t care what people put on their pizza, I simply avoid places that make “pizzas” in a non-italian fashion, like the american (supposedly NY style) ones where you get crust, 2 fingers of industrial cheese and a whole plant of oregano.

    It’s very similar for pasta, which many people think as a bread replacement.


  • I can’t really make an exhaustive comparison. I think k3s was a little too opinionated for my taste, with lots of rancher logic in it (paths, ingress, etc.). K0s was a little more “bare”, and I had some trouble in the past with k3s with upgrading (encountered some error), while with k0s so far (about 2 years) I never had issues. k0s also has some ansible role that eases operations, I don’t know if now also k3s does. Either way, they are quite similar overall so if one is working for you, rest assured you are not missing out.

    For too long it told men they can treat women however they want

    This is demonstrably false, as we have certain narratives that are literally millennia old (latin literature) about courtship, romantic gestures, protection and all the other stuff usually associated with how men should treat women. Usually this is some form of protection/care for a lower/weaker being, but it is absolutely a way society has been telling men how to tell women for centuries.


  • I would say that what you said applies not to feminism in general (who historically had strong links to class struggle and anticapitalism), but to a part of the modern status quo feminism which is focused purely on individuals and has been absorbed by the ruling class (e.g., once the CEO is a woman, the goal is reached). This is not a representation of feminism in general though, and I would say the same can apply to many other movements as well (e.g., ambientalism, antiracism, etc.) that (in part) lost their revolutionary nature and are left fighting for small changes within the status quo.

    I think that in fact in at least some cases the lack of respect (or general ability to live a relationship with a man in a mutually loving way) is exactly due to that education. At the end of the day the flipside of the “subservient” attitude is that the man in the relationship is represented as a provider, with all the gender stereotypes that come with it: lack of emotions, self-reliance and of course the expectation for him to be a provider. I would say that most of the examples of bad relationships in this thread boil down to exactly these dynamics.

    Also we are not anymore in the 1950, so that education today mostly happens implicitly, but it also gets mixed up with a lot of other messages from the wider society.

    I personally also disagree about the fact that men are not taught how to fit in their gender role. I think they are, since very little, symmetrically to how women are too and possibly even more explicitly: you need to protect women (incl. sacrificing because that’s what heroes do), the whole courtship thing, the fact that as a man you are responsible to provide for others, that there are certain activities that are manly, etc… Essentially is the exact same problem: gender stereotypes and sexism go both ways and impact both genders, although in different ways.
