5 VirtualBox Tips: How to Install Linux and More

VirtualBox is the excellent and user-friendly Type 2 Hypervisor that supports all the major operating systems. A Type 2 Hypervisor requires a host operating system to install on, and VirtualBox can be installed on Linux, Solaris, Mac OS X, and Windows. Then you can run any of these operating systems on VirtualBox as guests in virtual machines.

Virtualization is a big deal on servers for boosting hardware efficiency, and it is one of the foundation blocks of cloud technologies. In this fun era of powerful desktop PC hardware, cheap virtualization opens a vast world of possibilities. I use VirtualBox to keep multiple instances of development sandboxes, so I can freely experiment and blow things up without worrying about losing anything. (Note to the Internets: "losing". Not "loosing".) It's a fast and easy way to test distros and capture installation screenshots. Not that installing Linux is very exciting as it's been dead-easy for years. But it's nice to be able to do it.

unbound compile on Ubuntu / Debian (Linux)

unbound is a recursive caching DNS resolver. It is in the Linux area, "state-of-the-art" to either a public DNS resolver to operate, or to use it as an internal DNS resolver to resolve their own servers to independent providers of domain names.
It was written in C and is particularly stable, fast and easy to use. It supports inter alia following features:
  • Plugin for Munin
  • Manage their own local areas
  • Supports "prefetching" (similar to Google's DNS, that will expire before the TTL of a record is requested by the daemon in the background of this so the client does not wait more)
Since unbound at very early stage of development, and in the DNA area (perhaps because of DNSSEC or other security features) is currently doing a lot, it is highly recommended unbound prefer to compile itself, rather than relying on the Debian / Ubuntu repositories.

Reactivate the emblems on Nautilus 3.x

The move to Gnome 3 / GTK+3 also brought many improvements to the Nautilus file manager who adds revised and simplified interface even if the passage were also lost some functionality.
In fact, in the version 2.x Nautilus could add emblems that is, a small icon in the files and folders which allowed us a better understanding of the research or file content, features not present with the new release.
Finally, we can regain the emblems also on the new Nautilus 3.x through an extension called Nautilus Emblems Menu Extension which contains this functional directly accessible from our menu.

Install new emblems on Nautilus in Ubuntu 11.10 and 12.04 is very simple thanks to the dedicated PPA from the terminal just type:

sudo add-apt-repository ppa:dr3mro/nautilus-actions-extra
sudo apt-get update
sudo apt-get install nautilus-actions nautilus-actions-extra

and confirm. At the end restart our Nautilus typing in a terminal:

nautilus -q

and now from our context menu will have the opportunity to place the emblems in our files or folders.
