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!’

check your while condition, pls.
number is an integer
then you’re comparing it w a string
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

nil.to_i
