I find the use Aircrafts as the plural of Aircraft kind of sweet https://developer.schiphol.nl/apis/flight-api/aircrafts

Man, I'd just solved one of the problems. Hope I get a chance to find out how I did.

Those aren't the only sorts of motivation folks might have to work.

Plenty of people working in sewage, collecting rubbish and so on do it because they think it makes an important contribution to society, same as people in the army. I find it hard to disagree that their contribution is more important than software development in some ways -- I'd rather have streets clear of rotting rubbish and rats than a new version of office.

Sure, I think that this means that the try the normal case and the flipped case.

> ie. compare both hash(enteredPassword) and hash(invertCase(enteredPassword)) to the hash in the database and see if either match

Here's an example in bash:

  $ echo PasSwoRd | tr 'A-Za-z' 'a-zA-Z'
  pASsWOrD

In the database store one variant

  $ echo PasSwoRd | tr 'A-Za-z' 'a-zA-Z' | sha256sum > db

Then you can test both on input

  $ echo PasSwoRd | sha256sum > sum1
  $ echo PasSwoRd | tr 'A-Za-z' 'a-zA-Z' | sha256sum > sum2
  $ diff -q db sum1
  Files db and sum1 differ # i.e. LOGIN FAILS
  $ diff -q db sum2
  $ # i.e. LOGIN SUCCEEDS

The problem with the caps lock behaviour on Macs is harder. You definitely don't want to force to uppercase!
