  well, in my opinion it is a bit of a paradox. i think you are partially correct.

  your door analogy may be right from the perspective of the platform on which the cube is. however, one flaw is that the whole space is moving, not just the door. as soon as the cube enters that door, it will be inside that space, and if you consider the cube part of it, moving that space “downward”, then due the cube being held by the platform, you could consider the cube moving “upward” in the space behind the orange portal. if you consider preserving momentum there, then as soon as the apparatus stops moving, the cube should not stop its momentum and move further up in the space.

  or look at it like this: if you are behind the orange portal, meaning you are looking at the blue portal, you will see a cube moving towards you. then as soon as the platform hits the wall of the orange portal, the preserved momentum should make the cube “fly”.

  the change of perspective leads to two different conclusions, therefore i think it is a paradox.

  the problem sort of is that there are two “spacetimes” that are kind of being changed. one could interpret it as both of these effects “pulling” against each other since when the cube has partially passed the portal, one part of the cube is “in one of the spacetimes”, ant the other part in the other. ultimately though, the cube then would actually fly because in the limit (infinitesinally close to when the platform hits the portal wall) the cube is completely on the other side of the portal, so from the view of that spacetime, the cube does get pushed and should fly.

  i don’t even remember if it is possible in the video game for walls with portals that move. a video game would probablt have some kind of “center of mass”, like a single vector of coordinates where describing the position of the object. there is no notion of “partially” being somewhere (except for collision boxes, but i don’t mean that). so also from that view the box would fly. however, in most video games (with or without portals), if a platform moves up and suddenly stops, the object won’t travel further in that direction anyway, especially not ulwards (even sideways usually not).

  listen to the pete rock version of it. apparently (though not offivially confirmed), it’s the original version.

  mario odyssey being in the picture kind of already crosses the line since the game kind of makes some things difficult for you without internet connection.

  but i believe you could definitely play the game if all nintendo servers go down, so it does count.

  so in both cases, proton and mailbox, you have “less” snoopability, in the sense that they wouldn’t be able to snoop your stored mail retroactively. i am (in some sense naively) assuming “good” conditions here, such as that they don’t keep copies somewhere.

  of course without actual e2ee there is always a way for a provider to snoop any incoming email if they wanted to.

• ⁨Comment⁩ on ⁨E-Mail with own domain⁩ ⁨⁨5⁩ ⁨months⁩ ago⁩:

  actually, i was talking out of my ass a little. i am not sure itself how things work, i was under the impression that proton can’t access your clear text mails, once they are stored (of course, they can build backdoors that snoop when receiving mails, but we shall not assume this), similar to how mailbox.org allows you to have all incoming mails be immediately encrypted via your chosen pgp key, effectively having e2ee. i was under the impression proton did this automatically and stuff, i mean why else do you need to use their own apps for everything and to even use basic stuff like imap? but yeah i don’t know their setup exactly.

• ⁨Comment⁩ on ⁨E-Mail with own domain⁩ ⁨⁨5⁩ ⁨months⁩ ago⁩:

  you are correct in being wary of self-hosting email, i cannot recommend it. you definitely want a static IP (as oppoased to updating DNS entries all the time), a solid spam setup, and multiple failsafes, mesning not just data backup, but also mechanisms for preventing downtime like secondary machines. it really is only worth it if multiple people make use of it and you have multiple dedicated admins, in my opinion.

  as others have pointed out, use something like mailbox.org with your own domain, or other providers, or even a webhosting package from netcup or hetzner or similar. these are all solid and you have professional support.

  side note: downside is, your data there is more snoopable, less so with something like proton. but that shouldn’t be your biggest worry, since emails always exist not just on your server, but also on the other side of the communication, and you have no guatantees for privacy there. e2ee (like pgp) is what you would need in that case.

  “the” mapping? there is no “the” mapping.

  you are talking about the canonical inclusion mapping 1 in N to 1 in Z (restriction of the canonical inclusion of rings of integers Z into any other ring, Z is an initial object), which can be seen as a non-generic canonical mapping of semigroups.

  but as sets, there is no inherent structure, there are injection, surjections, and of course bijections in both directions.

  the only way one can call one set “bigger” is in the very strict sense of sets, N being a true subset of Q. however, this assumes N to be an actual subset of Q, which is a matter of definition and construction. so we say there is some embedding included, which is the same as (re)defining N as that embedded subset, so we are at your canonical inclusion of semigroups again. if you view this as inherent to N and Q, then there are “more” elements in Q as in N, but not in terms of cardinality.

  switch the order of the last two terms (the second equality), put the 0.01 in the middle, and it makes a bit more sense when read as calculation steps.

  0.04 * 75 = 4 * 0.01 * 75 = 4 * 0.75
