You clearly have not been to LGA before it was deconstructed. It felt like a 3rd world bus terminal; dark and oppressive. Thousands of people queuing up even in 12’ ceilings very quickly turns unbearable

Oh, I thought you were claiming an uncountable discrete subset of the reals (since your comparison was the rationals). Yes, obviously you can give any set the discrete topology (although the discussion of "between" suggests something more like an order metric?)

Oh, I hear you -- a while back I was curious why a cello and violin cost the same since a violin is so much smaller.

And the answer I got was that violins, being so small, are a lot harder to make because they're still as complex as a cello but, well, a lot smaller. That takes a lot more skill and specialised tools.

In more detail:

While some password hacks do go through the front end of the system; that usually doesn't work because of the account timeouts. Instead, most password hacks happen when a hacker gets hold of a website's password database. Given the database, a hacker can brute-force password guesses on their own computer without needing to deal with the front end.

Because in such hall constructions extra height is relatively cheap, lifting the roof higher doesn't add much cost, but it certainly makes the place feel roomier and with a bit of effort much more impressive. It's an ancient engineering trick, temples, churches etc do the same thing, it greatly eases sales no matter if you are peddling last minute tourist nick-nacks or a cult.

You have a list of passwords for some place that has been compromised.

You hack shitsecurity.com because they have shit security and discover that the user badpassword@gmail.com has a sha256 encoded password of

ef92b778bafe771e89245b89ecbc08a44a4e166c06659911881f383d4473e94f

You then crack this at home. Using a dictionary attack you learn that the password is (password123)

You then start to try other websites: say goodsecurity.com with the log in of badpassword@gmail.com and password123. Odds are the user reused there password for many websites and that if they have an account on goodsecurity.com you will get in.

There are a few reasons for this. First, high ceilings allow for better ventilation, which is important in preventing the spread of airborne diseases. Second, high ceilings make it easier to store luggage and other items out of the way, and to move around the airport more easily. Finally, high ceilings help to reduce noise levels, which can be important for both passengers and airport staff.

When someone tries to hack your Google account, for example, then can phish your login and password out of you by having you click on a malicious link. Once the get access to your account, then can change recovery information (additional email addresses and phones) to theirs.

And, by having that info, the hacker can reset the password.

However, in the resent days, it became much harder to change the recovery info without using original phone/email for 2FA (2 factor authentication) steps during password reset.

But if the hacker doesn’t need prolonged access to the account, they can just take info they need and not bother to get access anymore.

It's badly phrased. What I mean is that the most expensive instruments listed anywhere on Google are violins.

Other instruments on the rankings such as pianos or organs seem much more sophisticated to me as non musician. Why do violins take the top spots at any valuation ranking?
