why does my while loop never end?

puts 'Please enter a number:'
number = gets.chomp.to_i
while number != ''
if number > 0
puts 'You have entered a number greater than 0'
end
puts 'Please enter a number'
number = gets.chomp.to_i
end
puts 'Goodbye!'

Hello,

Is there any other source where I could download the gem
activerecord-sybase-adapter.

I have been trying to access http://gems.rubyonrails.org all day, which
hosts these adapters according to
http://weblog.rubyonrails.org/2007/10/1/adapter-gems-available but to no
avail.

http://gems.rubyforge.net didn't yield anything either.

I am upgrading to rails 2.0 and this is holding me back.

Many Thanks,
Aman

Because gets.chomp.to_i will never be an empty string ('').

''.to_i
--> 0

nil.to_i
--> 0
