Discovered that the entire Perl Cookbook is now available online. Originally i thought it's official from O'Reilly, but until trying to announce the url, i realized it's pirated. The site actually contains ~100 O'Reilly books. The url is 〔http://docstore.mik.ua/orelly/〕. Screenshot: ❐. The site is Google ranked at 5. (i discovered it while Google search Perl modules.) I guess the site is making money by the ads.
Ι wonder if O'Reilly knew. Ι hope they can take action, but i guess it's fruitless. Am also guessing that there are probably tens or hundreds of such sites. (they are all over bittorrent anyway.)
