Lost in Translation
Today I tryed to implement a functionality to create some CRM entities from email. I needed to retrieve an email, first name and last name (if possible) and body of the email. The last name is a mandatory property. I made a mistake when I used perlish style to initialize the last name: preg_match(‘/\”(.*)\”\s+\< (.*)\>/’, $from, $from_arr); $names = preg_split(‘/\s+/’, $from_arr[1]); $email = $from_arr[2]; $first_name […]

Perl is the best again
Perl core source code is tested using an open source software by Coverity, Inc: Ben Chelf, Coverity’s CTO, commented that “of the LAMP stack, Perl had the best defect density, well past standard deviation and better than the average.” Well, Perl demonstrated that it’s the best. At least in the LAMP (Linux, Apache, Mysql, Perl/PHP) area. But nobody knows about results of Java source code […]
