I think you don't have to. Otherwise you have to count hard disk drive
sector size (a file cannot have it's size < sector size, which is
usually 512 byte) :)

Well, I didn't make the rules. When you upload a file to the following
site (if it wasn't down):

http://golf.shinh.org/p.r...

The site saves the uploaded file and computes the file size. Regarding
your sector size, that's a separate issue. Save the code to a file and do:

ls -l fizzbuzz.rb

Surely we can knock one measly byte off of this sucker :)

Omit the new line:

-rw-r--r-- 1 schapht schapht 56 Mar 2 15:35 fizzbuzz.rb

Interesting. For me, vim shows 56 bytes of actual code, but ls shows 57
bytes, so I assumed that included an EOF character. There is no newline
in my file.

You sure? If you do File.read(filename) in irb is there a \n at the
end?

My bad - dude, you're a genius. Little did I know that Vim was sneaking
in an extra newline on me :(

So it's official, we're tied for 1st now - checkout comp.lang.ruby on:

http://golf.shinh.org/p.r...

I don't think I'll ever do a golf challenge again - what a time sync!
