  • It only does not have a significant adverse effect because enough people actually do pay for the media that they are able to make a profit off of it. If no one paid for it then they would lose all of their revenue from selling copies, which would definitely be a significant adverse effect on their profits.

    I mean, maybe you don’t consider that to be a problem. Maybe you think that copying media should be free and that instead of making money selling copies people should live off of the money they make from performances and/or patronage, even if this means that there is less money available to create media so in practice there is less of it around. I don’t agree with this position, but I also don’t think it is an inherently unreasonable one as long as you are being honest about it.

    The point is, though, that whatever moral position you take on piracy, you cannot justify it with a claim that only holds as long as other people act differently from you.



  • I can’t speak for other distributions, but Pop!_OS has had a “Refresh Install” option for a while now that does exactly this. This hasn’t happened often, but there have been a couple of times when something borked my system to the point of making it no longer boot, and re-running the installer in “Refresh Install” mode got everything back and running within 30 minutes while preserving all of my non-system files; in particular this meant that I didn’t have to re-download my Steam and other locally installed games, which is significant because they are the largest apps on my system.






  • There are lots of possible choices of universal gate sets. However, if you are starting with Clifford gates, then it turns out to be sufficient for you to add support for a T=sqrt(S) gate; essentially T and H have the property that these two gates by themselves are sufficient to efficiently approximate any 1-qubit gate arbitrarily well (by combining these discrete rotations about the two different angles in the Bloch sphere in specific ways via the Solovay-Kitaev Theorem), and being able to perform an arbitrary 1-qubit gate and having access to an entangling 2-qubit gate (CNOT) lets you extend this to an efficient arbitrarily good approximation of any gate on an any number of qubits.
