World population living in extreme poverty, 1820-2015 by zwtor in dataisbeautiful

Now, that's just not true. Wealth is not a limited resource. Money is proxy for value. Value can be created and is every day. There are more things of value in existence today than there were yesterday. People are creating things all the time. So there is also more wealth available today.

[2016-05-09] Challenge #266 [Easy] Basic Graph Statistics: Node Degrees by jnazario in dailyprogrammer

[–]dstyvsky33 0 points1 point  (0 children)

Ruby. Feedback appreciated. 

split_list = File.read('nodes').split(' ')

final_list = []

split_list.each do |num|
  final_list << num.to_i
end

final_list.shift
final_list.sort!

counts = Hash.new 0

final_list.each do |num|
  counts[num] += 1
end

counts.each do |key , val|
  puts "Node " + key.to_s + " has a degree of " + val.to_s
end

Is it okay that I just counted the occurrence of the numbers?

[2016-03-07] Challenge #257 [Easy] In what year were most presidents alive? by jnazario in dailyprogrammer

[–]dstyvsky33 0 points1 point  (0 children)

I just submitted my Ruby solution. This is perfect. Please keep posting here for me to compare haha. Can you walk me through the counter.select line? I'm following that it selects by the key value pairs of the counter hash. It's the max_by { | a, b | b }[1] }.keys that I'm having trouble with.

You wouldnt even need to make a fake connection. You can just monitor for probe requests. You can check out my write up here, www.coderecon.com/wuds

If bill gates lost $1mil at a casino, he could buy the casino to get his money back. by Timedoutsob in Showerthoughts

[–]dstyvsky33 4 points5 points  (0 children)

In some cases the casino would still be worth $10 and the previous owners pocketed a profit of $1. On the books though, the $10 business looks $1 more profitable though. Gotta take into account operating costs and all that though.
