Higher-Order Perl Available For Free Download
Christopher Cashell writes "As noted on Perlbuzz, Mark Jason Dominus's amazing book, Higher-Order Perl, is now available for free download. This is a great book that goes way beyond your normal programming reference. This will change the way you look at programs, and make you a better programmer in any language. It sits on that special shelf reserved for books like Structure and Interpretation of Computer Programs, The C Programming Language, and The Practice of Programming."
It is truly awesome that mjd is making this available for free.
It's still worth buying the dead tree version, though.
a good programmer can write a script which does the same thing whether run in perl or executed as sendmail.cf
