Hi  
Someone knows why this source

#! /usr/bin/env ruby

require ‘socket’

srv = TCPServer.new ‘localhost’, 20000  
loop do  
Thread.start (srv.accept) do |s|  
s.write time.now  
s.close  
end  
end

causes this?:

code/ruby/stuff/socket.rb:5:in `<top (required)>': uninitialized constant TCPServer (NameError) from ./socket.rb:3:in`require’  
from ./socket.rb:3:in `’

Also:  
ruby -v  
ruby 1.9.1p378 (2010-01-10 revision 26273) [x86\_64-linux]

It seems to happen only to me =\

It happens to me too, when I name my file socket.rb and use Ruby  
1.9.1. I’m not sure why, since “.” (current directory) is at the very  
end of the load path, but it appears to be loading your socket.rb  
instead of the Ruby one.

I think 1.9 started preferring .rb files over .so files, where possible.
