Ruby on WRT54G(L)
204596 [jim@fr ez .o] Has anyone installed Ruby on a WRT54GL router?
204607 [nahteecirp@g] I would definitely be intrested in your results. Out of curiousity,
204616 [jim@fr ez .o] I'll be building an ipkg and putting it on the WRT54GL.
204667 [nahteecirp@g] Oh, ok, I jurt assumed you might be doing this through a third party
204672 [jim@fr ez .o] Actually, openwrt. I've heard bad things about dd-wrt wrt the nvram state.

Bug in ruby printf/sprintf
204644 [paul.dlug@gm] I have encountered what appears to be a bug in ruby's printf/sprintf
204649 [jromano@bu i] The equivalent C program under RedHat Linux 3 update 6 x86_64 produces

  204774 [pbattley@gm ] Nice solution.
  204778 [Eric.Armstro] I'll say! Wild! What makes /that/ work???
  204784 [w_a_x_man@ya] \& is simply what was matched by the regex.

Custom Exception classes
