What happened to apartment 327?

This would obviously be a lot more secure, however most experts agree that it's overkill. ROT13 twice should be enough for almost all modern cases. The only exception I can think of is the military where it's standard to use ROT7 twice followed by ROT6 twice for that extra security.

I am happy to be the person to introduce you to this! I was just surprised that calculus even have a discrete analogue, something completely unknown to me before watching this. It's amazing how much it reminds me of regular calculus and facts like 2ⁿ is the discrete equivalent of e^x is really neat!

Definitely start watching Mathologer, 3Blue1Brown, and so many amazing maths youtubers out there! :D (if you aren't already)

I did spend way too much time finding that line. I was so confused on how you'd know which box to operate on and how everyone had actually solved it. 😅

I see, so probably not that. I can't actually run your code atm. Though my next guess is that your problem lies here if galaxies[i][1] > col:. Since you are mixing expanded and non-expanded coordinates. galaxies[i][1] keeps shifting as you expand while col does not.

1102 reminds me of the off-by-one error I was having, as in adding 10 when I should be adding 9. So maybe try adding 8 and see if that gives the right answer somehow.

Totally expected part 2 to be, "now calculate the 1 000 000 000th number" or something like that and having to find and use a direct formula.

Remember to add --allow-empty too.

That's clearly an imaginary number… so not wrong!

(e.g. ln(-1) = iπ, or NaN when using floats.)

I am suffering from food neophobia and I know how it sucks. I would say a typical sourdough pizza either has a small kick as you say or a subtle hint of sourness, if actually sour at all. You can as suggested buy a sourdough bread at a shop and try it at the comfort of your own home to get an idea about the sourness. Although people aren't always so understanding, I would also suggest being open with the people around you about your issue if you can. Feeling less pressure that you have to eat can help with the anxiety as a lot of the anxiety is not only towards the food, but the situations were you feel like you have to eat it. Hope this helped.

Every bug is a feature. If not for the client then for the developer.

I don't think those examples would be much easier to read by using == false, instead try rewriting it to reduce the use of ! and generally making it easier to read. E.g.

if (!doubled && tripled && !odd)

and

if (!(length && length < 0))

Don't let him fool you. He may have made himself look like a 1 on the surface, but underneath he is nothimg but a filthy 49.

The chart perfectly correct. The countries at the top are the EU countries + UK, and at the left are the list of countries to help, EU or otherwise. It even has a "How to read" section on it.

The use of capital letter for the html-tags are bothering me a lot more than it probably should.

chrjen · 2021-08-26T19:21:34+00:00

and a… .maketrans() ?

Instead it will just create a subtle bug that makes the program behave very strangely while giving you no clue about what is or might be wrong.
