hi there, I just write a ruby program mirror to its python version to\nfeel the difference between the two fantastic language. here is the\nruby code. [URL]http://paste.pocoo.org/show/530185/[/URL]. But I found it\ntwice slower(1.09 seconds to run) than its python counterpart(0.34\nseconds to run). I think I made some mistake in writing this ruby\ncode. How can I make the ruby code faster? I'm using MRI 1.9.2, and\nthe file 0103.log is a 60000 lines file.
