Take our sysadmin masterclass in Linux User & Developer 139

Also inside we have tutorials for building Android apps with Kivy, analysing code and creating your own CCTV system along with a report from our very first Raspberry Jam

This month we ask the questions: what does it take to be a system administrator? We take you through the core tasks of working as a Linux sysadmin, mail servers, web servers databases and more as we attempt to teach you the skills required to get a job in Linux.

In this issue we also have a full report on our Raspberry Jam that we held in Poole, Dorset in early April. Find out how people of all ages enjoyed a day of learning and hacking by the sea with Raspberry Pi’s and Pi-powered machines. We also have several Raspberry Pi tutorials in the issue which include slow-motion video, tilt controllers with the XLoBorg and the low down on the GPIO pins.

You can get issue 139 of Linux User & Developer today at your local newsagents, online at the Imagine Shop and digitally at
