    I have a number of test platforms which I use, and last week I started one which had been offline for a number of months.

  • Blog: Building a Plex Media Server

    If you’re anything like me, you have a considerable amount of downloaded content (music, tv shows, movies) stored away on a desktop PC. Over the years this library has grown considerably and back in the day before the plethora of mobile devices we now own, having this only available on the desktop was fine. However, in 2017 this ‘stuff’ needs to be accessible on all your devices.
