Talk - Debugging {php,ruby,anything} as a Linux sysadmin

This talk will explore the "other side" of debugging: the one from a sysadmin point of view. We'll look at malfunctioning code and debug it using tools like netstat, lsof, strace, sysdig & more to find the root cause. At the end of the talk, you should be armed with the knowledge to troubleshoot any kind of application (PHP, Ruby, Perl, ...) on a Linux server.
