In Slovak, instead of "pi" (3.14159265...), we say "pí", which is pronounced pretty much the same as "pee" in English. So this guy needs someone to "tau" him home.

You need to have a user account. It's quick to make one, so it only comes down to whether you're willing to do so.

Yes, but the humor that comes out of it is really good. I think it's worth it. "Great Wave of TuckerKao", that's just golden.

I propose the name "Great Wave of TuckerKao" - to be pronounced "Tuck-er-cow-uh" (a play on the name of the woodprint - Great Wave off Kanagawa) from the collection of "168 ranges of Mount Bullshit"...

You have pointed out another selfish aspect of it - creating for the sake of reward, not for the sake of the creation itself.

Angry On intellectual property and government surveillance

I am just going to say that I believe the concept of intellectual property is one of the most extreme displays of human selfishness, at least in its present-day form.

In case you'd (or anyone else) like to have a go with my code and try something:

Switched up the digits, but the number is correct for the 27.52 value, so it's just a cosmetic issue.

I have gone through the prime powers from p^2 to p^9, manually on paper (quite easy, and I could have done more, but I decided to rather make the program for this). I have found that they all end in...

Well, it only uses division by 2, which can be done as a right-shift, and addition and value comparing, so if it works as intended, then I believe it is much faster - at least algorithmically, as it...

This one is trivial. If the square number is even, it must be divisible by 2, and also 4, as all powers of prime divisors of squares must be even for it to be a square number. If you take a square s...

I've noticed a mistake I made. Oddly enough, it fixed itself. Under my gcd rule, 9 goes to 3, not 18 (while doing those first few numbers in my head, I probably forgot to add 1 to the power 2 in...

Let me correct you.



I was explaining my improved version of the original rule for the sequence. Thus 75 goes to 50. At least in my version, that is.
