Uber Price Discrimination - different user has different price for exact same pickup/dropoff

By Brownie -
Recently, I start to notice that Uber shows significantly different price for the exact same route using my account or my husband's account.
UberX from my home to airport shows $39 with my account and it goes up to $46 with my husband's account. I guess he uses Uber a lot more often than I did, and Uber figured they could charge him more.

 Everyone is talking about surge pricing, pool vs x, but not this.
Price discrimination is everywhere.
Check the price with your friend's phone next time and see it for yourself.

Project Euler Problem 684 Inverse Digit Sum - Solution

This one is relatively straight forward. Below is a solution in python and will give us correct answer within reasonable amount of time. (Generally, if python can calculate this fast enough, I am happy with the solution, nothing against python...) modulo = 1000000007 #speed up hint: (10e9) % modulo = -7 #init speedup array shortcut = 18 arr_lookup = [ 1 ] * (shortcut + 1 ) for i in range ( 1 ,(shortcut + 1 )): arr_lookup[i] = ( 10 ** i) % modulo def S (i): A = i % 9 B = i // 9 #sum = (1+..+A)*(10^B) + A*(10^B-1) + 45*(10^(B-1)) + 9*(10^(B-1)-1) + 45*(10^(B-2)) + 9*(10^(B-2)-1) + ... + 45*10 + 9*9 +45 #sum = (A(A+1)/2)*(10^B) + A*(10^B) - A +(9+45)*(10^(B-1) + .. + 1) - 9*B #sum = (10^B) * (A(A+1)/2 + A) - A - 9*B + 6*(10-1)*(10^(B-1) + .. + 1) = (10^B) * (A(A+1)/2 + A) - A - 9*B + 6*(10^B -1) #sum = (10^B) * (A(A+1)/2 + A + 6) - (A + 9*B + 6) #since (7,10e9+7)=1; 7^(10e9+7 - 1)%(10^9+7)=1 #B = 18C+R C = B ...

Project Euler Problem 686 Powers of Two - Solution

Powers of Two     Problem 686 2 7 = 128 2 7 = 128  is the first power of two whose leading digits are "12". The next power of two whose leading digits are "12" is  2 80 2 80 . Define  p ( L , n ) p ( L , n )  to be the  n n th-smallest value of  j j  such that the base 10 representation of  2 j 2 j  begins with the digits of  L L . So  p ( 12 , 1 ) = 7 p ( 12 , 1 ) = 7  and  p ( 12 , 2 ) = 80 p ( 12 , 2 ) = 80 . You are also given that  p ( 123 , 45 ) = 12710 p ( 123 , 45 ) = 12710 . Find  p ( 123 , 678910 ) p ( 123 , 678910 ) . Test the first 3 digits of a large number is quite costly.  So first thing first, think log(). --------------------- import math lowerbound = math.log(1.23,10) upperbound = math.log(1.24,10) def testlog(i): logi = math.log(2,10)*i diff = (logi - int(logi)) return diff We only care about the part after decimal point, thus  dif...

Project Euler Problem 717 Summation of a Modular Formula - Solution

Summation of a Modular Formula          Problem 717 For an odd prime  p p , define  f ( p ) = ⌊ 2 ( 2 p ) p ⌋ mod 2 p f ( p ) = ⌊ 2 ( 2 p ) p ⌋ mod 2 p For example, when  p = 3 p = 3 ,  ⌊ 2 8 / 3 ⌋ = 85 ≡ 5 ( mod 8 ) ⌊ 2 8 / 3 ⌋ = 85 ≡ 5 ( mod 8 )  and so  f ( 3 ) = 5 f ( 3 ) = 5 . Further define  g ( p ) = f ( p ) mod p g ( p ) = f ( p ) mod p . You are given  g ( 31 ) = 17 g ( 31 ) = 17 . Now define  G ( N ) G ( N )  to be the summation of  g ( p ) g ( p )  for all odd primes less than  N N . You are given  G ( 100 ) = 474 G ( 100 ) = 474  and  G ( 10 4 ) = 2819236 G ( 10 4 ) = 2819236 . Find  G ( 10 7 ) This problem is not really that complicated to reduce to acceptable execution time.
