Link: How to Turn Off Shutdown Confirmation Dialog Box in Ubuntu

To shut down or restart your Ubuntu machine, you click the Power button on the top panel and select the shutdown option which in turn opens another confirmation dialog box where you have to confirm your action of shutting down or restarting your Ubuntu machine. This same confirmation dialog box will also appear whenever you try to log out or lock your Ubuntu machine.

Of course, this feature is there to save you from the unnecessary shutting down and restarting of your Ubuntu machine. But if you have been using Ubuntu for a long time, then accidentally pressing the Shutdown button is pretty rare. That said, apart from being useful, this feature is kind of annoying, as sometimes we may forget to confirm our action due to things like ignorance or workload which in turn leads to unnecessary power consumption. Here is an easy way to turn off the Shutdown and Restart confirmation dialog box in Ubuntu 14.04.

Link: Setting Up Multiple Isolated Linux Systems (Containers) Using LXC On Ubuntu 14.04

LXC, Linux Containers, is a fast, lightweight, and operating system-level virtualization technology that allows us to host multiple isolated Linux systems (Containers) in a single host. Unlike other virtualization methods such as VirtualBox, KVM, and Vmware, the guest systems uses the same kernel of the host system. All guests will efficiently shares the resources such as CPU, RAM, Hard disk, and network etc of your original host computer. The main goal of LXC is to create a Linux environment as close as a standard Linux installation, but without the need for a separate kernel.

Link: Tutorial: Raspbmc PVR TinyUSB2 DVB-T & TVHeadend All-in-one

Note: We hesitate to post this link because DVB-T is NOT used in the United States or Canada (we use ATSC).  It IS used in many other parts of the world.  But the reason we are linking to is is because some of this information might be adaptable to use of an ATSC (digital television via an antenna) or a DVB-S or DVB-S2 (free-to-air C-band or Ku-band satellite) tuner, all of which can be used in North America.  However we do not guarantee that, and we can’t tell you what parts of the instructions would need to be modified to make it work with one of those types of tuners.

Thought I would post my first attempt to build an all-in one XBMC LiveTV and PVR running Raspbmc and TVHeadend. Credit is given to Quonith for his awesome tutorial upon which this is based: http://forum.stmlabs.com/showthread.php?tid=2648.

This particular tutorial is using the Digital Now TinyUSB2 DVB-T with TVHeadend as the TV server. I am looking to do away with my power hungry Windows 7 Media Centre PC and this is more od a proof of concept more than anything. At this point in time, I still prefer Windows MCE as it ‘just works’ and is very intuitive for the user (most important of all). None the less, this was good fun.
