Cron jobs in Linux are simple scheduled tasks that can be set to run commands at specific times. Unfortunately, the syntax isn’t the easiest to use or remember, but in this month’s column I’ll share some examples and tips to help you better understand and utilize cron jobs.
XBMC is a media center application that started its life as a project to turn the first-generation Xbox into an audio and video powerhouse. The project has since been ported to run on Windows, Mac, Linux, Android, and other platforms, and we’ve even seen it running on low-power devices with ARM processors such as the Pivos XIOS DS Media Play.
Now there’s a new XBMC box on the way, and it’s designed specifically for running XBMC. It doesn’t run Android apps at all, just an embedded operating system to support XBMC.
Fail2ban is an intrusion prevention framework written in the Python programming language. It is able to run on POSIX systems that have an interface to a packet-control system or firewall installed locally (such as, iptables or TCP Wrapper).
Fail2ban’s main function is to block selected IP addresses that may belong to hosts that are trying to breach the system’s security. It determines the hosts to be blocked by monitoring log files (e.g. /var/log/pwdfail, /var/log/auth.log, etc.) and bans any host IP that makes too many login attempts or performs any other unwanted action within a time frame defined by the administrator.
Today I want to show you some configurations that you can use to improve the security of your Apache.
In VLC’s preferences, note the setting for “Use GPU accelerated decoding” — on most systems with modern graphics hardware this should be checked, but is not by default. So, check the box and then click Save. You can always change it back if it makes things worse, or causes videos to not play at all.
This setting does not seem to be available in OS X versions of VLC.
