• Should require two or more items in webshop
• Should always request the price for four items, no matter how many there are available
• Should reduce score if another item already has the same price
• Should always order four items, no matter how many there are available
• Should give a huge score on successful completion (500?)

See if the sleep can be reduced dramatically when there's 20 players. Maybe sleep time of 1 second, both for ok and failed questions.

Add some questions that will trip a correct, but slow implementation up.

Code from server:

def correct_answer
  n = which_number
  root5 = Math.sqrt(5)
  phi = 0.5 + root5/2
  Integer(0.5 + phi**n/root5)
end

This fails miserably on larger fibonaccis due to precision issues. sqrt(5) is an irrational number, its precision is calculated to over 1 mill decimals. Ruby float: Math.sqrt(5) == 2.23606797749979 is just too imprecise.

It actually fails already with fib(71):

def gr_fib(n)
  root5 = Math.sqrt(5)
  phi = 0.5 + root5/2
  Integer(0.5 + phi**n/root5)
end

>> (69...72).map { |n| gr_fib n }
=> [117669030460994, 190392490709135, 308061521170130]
>> 117669030460994+190392490709135
=> 308061521170129

I suggest you use an iterative version instead. For instance:

def fib(n)
  a, b = 0, 1
  (0...n).each { |_| a, b = b, a + b }
  a
end

• Create three player servers
  • One that answers nothin
  • One that answers a few questions
  • One that answers all questions
• Start the server
• Registrer about 20 copies of each of the player servers with the script under utils
• Let it sit for 10 hours

After a question has been answered correctly 10x times, reduce score to 10%

After a question has been answered incorrectly 10x times and never correctly, reduce penalty to 1% of base score

After a question has been answered correctly, increase the penalty to 20%

An error in a question should never make the server crash!

When user has responded to warmup question, automatically provide a few more.

Also: Make the display show which users have never answered a question correctly

"You depart CPH for OSL at 2011-10-28 23:00. Flight time is 3 hrs, 30 minutes. When do you arrive?"

Add a question that sometimes don't have an answer. Learning benefit: "Sometimes, the customer will never be happy. You have to ignore the haters and move on".

Some of these questions may make the server bomb

Possible:

• "what is the arcsin of {1}", where {1} is -1.1 - 1.1 (arcsin(1.1) is undefined)
• "what is 3 / 0"
• "what word is number 8 in "all the kings men""

Log a session in such a way that we can look at what happened to an individual player and what questions got answered wrong and right. Log files should automatically be unique after a restart.

In order to specialize in different parts of the game, as a player, I want the game to introduce more questions in the areas of the game where I've made progress.

Reproduce:

• Start server
• Register player
• Answer some questions
• Close client
• Watch server crash
