I dont think redundant questions are the problem. But people's historically short responses on reddit definitely were. Responses like "have you tried googling it" or "the question has already been answered, try searching before you post" do nothing but ostracize the person asking and make communities unwelcoming. I would like to see Lemmy more understanding, as to encourage and attract novice individuals in communities they are interested in

The problems which are calculated, such as finding prime factors of an integer, take non-polynomial (NP) time on a classical computer to solve. But NP problems, as opposed to NP-hard, can by definition be confirm in P (polynomial) time on a classical computer. Therefore, we can easily confirm that the answer is correct using classical computers.

On an aside, I used the example of prime factorization because it is one of the most well known problems that can be accelerated via quantum computing using Shor's algorithm. Using Shor's algorithm on a quantum computer, an integer can be factorized in P time. This is opposed to NP time on a classical computer.

While I agree with the sentiment that it is technically stealing. No one should worry about charging their phone in public. Atleast in the region of the US I am located, it costs about 1-2 cents per year to charge your phone. So charging your phone for one sitting would be a miniscule amount of money. Just opening the door of the business and letting the conditioned air out would cost them more.

Obviously cars are an entirely different situation since one charge can be several if not tens of dollars.

What is the reasoning behind the not rusty warning?

Also, note that this acceleration provided by Shor's algorithm is what people are talking about when they say "quantum breaks encryption". I don't like when people say that though because quantum computers don't break all encryption schemes. In fact, there is only one mainstream encryption scheme which is susceptible and that is RSA. Don't get me wrong, if RSA is comprised that would compromise a LOT of legacy systems. But we already have new public key ciphers, such as elliptic curves, which are ready to replace RSA once quantum computers become large enough to actually implement an attack against RSA.

I'm surprised I don't see more people recommending KeePassDX! I agree and feel much more secure knowing exactly where my encrypted password vault is.

Also I recommend that people use Syncthing alongside KeePassDX so you can host your own cloudish environment to share the password vault between your devices. Keepass 2 is a great Windows/Linux application for interfacing with the .kbdx vault file format used by KeePassDX.
