    There is no probability. No rolling dice. It is every combination of everything. I know Hilberts infinite hotel, I know (enough about) probability and statistics.

    I am talking about the multiverse that many people imagine. The one where you can say “there is a universe in which I am president. And one where Lincoln is a velociraptor, and a universe where chairs sit on people instead of the other way round”. In that multiverse, I can construct a universe without triangles that is identical to another universe with triangles in every regard except for the existence of triangles. And I can do that for every universe with triangles. Its a bijection.

    We dont permute a (in)finite set of initial parameters and then evolve the universe from there, we have a universe for every CURRENT state.

    In the hypothetical reality where such a multiverse exists (it would be a case of Russells paradox as OP has discovered), there is a 50% chance to be in a universe where it doesn’t.


  • Standards are used to increase interoperability between systems. The more different standards a single system needs the harder it is to interface with other systems. If you have to define a list of 50 standard you use, chances are the other system uses a different standard for at least one of them. Much easier if you rely on only a handful instead


  • I think it is reasonable to say: “for all representation of times (points in time, intervals and sets of points or intervals etc) we follow the same standard”.

    The alternative would be using one standard for points in time, another for intervals, another for time differences, another for changes to a timezone, another for …

    I know. But I case of the multiverse that many people think about, the one where there is a universe for EVERYTHING, there will be exactly as many universes where triangles exist as there are universes where triangles dont exist. And the same is true for everything else.

    And it is exactly the same number, not just the same type of infinity. Because for every universe with triangles there must also exist the exact same universe without triangles (and vice versa), otherwise the multiverse wouldn’t contain all possible universes.

    If there are infinite universes, covering all permutations of all properties (i asume thats what they mean by omniverse), then there will be exactly as many universes with a certain property then there are without it. So it is actually 50/50.

    In the “multiverse of all possibilities” there will be 50% without a multiverse






  • While I agree on the facts I want to offer a slightly different (possible) conclusion: a organisation like wikileaks needs resources and supporters. If they are targeted by all the “good guy”-countries and the only one willing to support them is “evil guy” Russia, then they are not in a position to resist. They chose to compromise their integrity instead of just not existing.

    If the western world wants a whistleblower/leaks organisation that follows journalistic integrity and ethics, they need to fund it even if it leaks their own internal documents.



  • Would you need a power source? If you aim your ship correctly, then put everything alive into cryo, the ship could go completely dark, vent all heat and become a frozen rock. Then after [very long time] the ship enters the vicinity of a different star and can be reactivated and unfrozen using solar energy. You dont need energy to maintain cryo if the whole ship is at 1° kelvin.

    (Of course that relies on cryo sleep being possible)

    If your train is canceled, your ticket is automatically valid for all other trains going in the same direction (doesnt have to be the same route, as long as it will reasonably take you to your destination) for the whole day.

    Depending on how mutch later the next connection arrives, you can get all/parts of your ticket price back.


  • … They can littetally not walk “freely”. If they show interest in the wrong person they are stoned and burned exactly the same. Gay/Lesbians can also escape prosecution, they just have to hide who they are. Same as the BI person. Bi means beeing attracted to male and female and they have to surpress and hide that attraction or face persecution. That is not free.

    A straight person how is persecuted for being attracted to anyone not called John/Jane isnt free just because there is someone they are allowed to be attracted to legally.


  • Deleting a file does not overwrite the data. It just marks that area of the drive as “free”. Using forensic tools (or simply dd) you can read data from “empty” parts of the drive. To be save you have to overwrite each file. You can try tools like shred to scramble the data of a file before deleting it, but as they say themselfes, unfortunately your filesystem might not actually let you do that (scroll to the CAUTION section).

    You can use dd to write bytes to arbitrary places of the drive, but again, the filesystem might lie to you where a file is actually located. The ONLY way to be entirely sure is to wipe the whole drive. And if your IT does not do that before handing a system to a new employee, then they are not doing their job correctly.

    Not legal advice: just tell them you installed a few viruses (while the system was not connected to the company network of course) and they should nuke the system before handing it to anybody else.

    (You can also wipe the drive yourself by booting from a stick and overwriting the entire drive)
