Perl is useful too

I subscribed the mail lists of china-pm and bio-perl-pm. Actually I didn't look into it very carefully until just now. Some guys introduce the use of perl to develop the plug-in for firefox, which shocks me a lot. Perl can be used to such a high level, but I give it up. Anyway, regret is useless. Try to grasp both Perl and Java. Be a good programmer soon.
