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.


With over 10y experience in both Linux server management & PHP development, Mattias is soon both the dev- and the ops-side of things.

He’s always on the lookout for new interesting technologies to play around with. He’s building Oh Dear! and DNS Spy, two different SaaS projects aimed at monitoring the web.
