  • Another commentee has already said that Artemis is a political stunt. I believe it’s worked magnificently. Space travel is being used to whitewash USA’s reputation and at the same time display the US’ continued military and technological dominance. It’s another message to all other countries in the world that they are going to stay slaves to US imperialism and dictatorship.

    As shown by the comments here, the USians have no problem with their government if they get to see shiny new nerd pictures.



  • The flag -y refreshes the package list (like apt update). For some reason, you use the flag -yy to force it to clear the whole package list and redownload everything.

    To allow package downgrades when upgrading you use -uu.

    These are very commonly suggested fixes to arch package management problems, for example when you leave your arch install to suit for too long, it will be impossible to update it because of dependency problems. So you google it and people are saying to run “pacman -SSyyuu” or other such commands.

    Those additional options should be their own flags, command line flags should be idempotent (it should flip a switch on, doing it multiple times shouldn’t change anything).

    This is just not true. The normal limit we have here means a limit would have to exist from both directions and they should be equal. They’re not, so the limit doesn’t exist.

    One-sided limits would be denoted by x -> 5– and x -> 5+ or similar.

    PS: in complex analysis, there is no distinction between +infty and -infty, so there it would be correct to say the function has limit infty at 5.










  • From skimming through the actual paper, it seems that quantum gravity is a theory of physics, more general than general relativity, where spacetime itself is something that’s generated by a formal system of a formal language, a finite or small infinite set of axioms (fundamental physical laws) and rules for the creation of algorithms. What’s seemingly proved in the paper is that there are theorems in this system which cannot be proven, because they are too complex. But theorems in this sense mean states of spacetime or energy or whatever, meaning that ultra-complex states cannot be modelled with this model. And allegedly these kinds of ultra-complex states occur in high-energy situations.

    I’m not saying it’s gospel but the article isn’t as absurd as it first seems. Still I doubt this actually proves us not living in asimulation.



  • Won’t work sadly, the “counter sound” can’t be in phase in multiple locations because of delay and reflections. Headphones can do ANC because the ear is basically a single point so the mic can pick up exactly what you’re about to hear and then compensate.

    Using a speaker like that would just create double the leafblower noise.
