What About Sabayon Linux?

Installing Sabayon Linux is much easier than installing Gentoo, because you don’t really have to tinker with command lines to do so.  Even when computer users who want to install Sabayon Linux onto brand new hard disk, they don’t really have to use the ugly Fdisk text script to create new partition table for their hard disk.  Wait, let backtrack a bit.  Why do a computer user who wants to install Sabayon Linux need to create brand new partition table for his or her brand new hard disk?  It’s because a brand new hard disk has no partition table to start with, and Sabayon Linux isn’t going to recognize a hard disk if it has no partition table.  So, without using the ugly Fdisk, what can a computer user use to create new partition table for brand new hard disk in Sabayon Linux?  Simple, when running Sabayon Linux in LiveCD environment, just use the command line emerge to install Gparted.  Like this, {emerge gparted}.  Once Gparted has been installed onto Sabayon LiveCD environment, you can use Gparted to create new partition table for your brand new hard disk.

Gparted is prettier and easier to use than Fdisk since it’s a graphical user interface with intuitive features, therefore it’s a welcome sight for new Linux users.  Hint:  once Gparted is installed onto LiveCD environment, it’s existed inside RAM only, because rebooting the LiveCD, you would reset LiveCD environment back to the default, out of the box settings again.  This action removes Gparted as if you had never installed Gparted, ever.

After you have created new partition table for your brand new hard disk, you only have to open up a terminal, become root, and then type in the command {installer} to fire up the installer manager’s graphical user interface.  At the installer’s graphical user interface, you just have to read the options it presents to you carefully and follow through the onscreen instruction within the installer manager to complete the installation process of Sabayon Linux.  As now, Sabayon Linux is at version number 8.  Once you had installed Sabayon Linux, make sure you remove the LiveCD and reboot your computer so you can boot into Grub and from Grub into Sabayon Linux.

Basically, using Sabayon Linux is pretty much similar to how you use Gentoo.  So, your first task is to make sure your Internet is working within Sabayon Linux.  Once the connection to the Internet has been established, you can begin the update process for Sabayon Linux.  How?

  1. Open up a terminal, become root, and type in {emerge –sync}
  2. When emerge –sync is done, type in {layman -S}
  3. If the system asks you to do emerge portage, then you should do so. How?  Type in the command, {emerge portage} into terminal as root.

So, what on earth is emerge?  Well, emerge is sort of like Yum on Fedora, Yast on openSUSE, apt-get on Ubuntu, and so on.  Basically, emerge is based on Portage.  Portage is the real package manager behind the scene which allows emerge to call it to interact with source packages.  So, when you do the command emerge –sync, you’re actually telling emerge to update Portage package manager’s source archives/packages.  You can view emerge as command line tool which interacts with Portage (i.e., the package manager).

In my opinion, it seems Gentoo and Sabayon Linux rely on source packages and not binary packages, therefore installing software onto Gentoo or Sabayon Linux would be slower than doing the same thing on Ubuntu or Debian based Linux distributions.  Installing a source package usually requires the computer system to compile the source package first before the actual installation would begin.  Ubuntu or Debian based Linux distribution uses binary packages more often than source packages, therefore installing software on Ubuntu or Debian based Linux distribution is going to be faster as everything had already been defined.  Nonetheless, I think installing from source packages does have an advantage over binary packages, because installing source packages would only define the necessary features and variables and elements of a software that fit a specific computer environment.  This way the installed software might perform better and be more stable than otherwise.

So how do you go about installing software on Sabayon Linux (i.e., same for Gentoo)?  You do the following.

  1. Let say you want to install ClamAV onto Sabayon Linux, you would open up a terminal.
  2. Become root!
  3. Type in the command {emerge clamav}.

Let say now you want to remove ClamAV from your Sabayon Linux system, but how?  You do the following.

  1. Open up a terminal!
  2. Become root!
  3. Type in the command {emerge -c clamav}

In summary, using Sabayon Linux is very similar to how you would use Gentoo.  Obviously, if you never have played with Gentoo before, you might want to try Sabayon Linux out first since installing Sabayon Linux is easier than installing Gentoo.  Remember, it’s not that straight forward when you try to install Sabayon Linux onto a brand new hard disk, because you have to go through the process of creating a brand new partition table for your brand new hard disk.  VirtualBox users should go through the same process as users who want to install Sabayon Linux onto brand new hard disk, because VirtualBox users would have a brand new virtual hard disk when they create a brand new virtual machine.  When done installing Sabayon Linux, you should learn how to use emerge command lines to update Portage package manager, install source packages, and remove source packages.  Other than these necessary command lines and procedures, users should be able to use Sabayon Linux with ease since most things are accessible through graphical user interfaces.

Ubuntu Expands To TV, A Video Shows A Gorgeous Ubuntu TV Prototype In Action

Couple computers of mine are using Ubuntu as their main Linux operating system.  (Ubuntu is one of the easiest Linux distributions to be installed and used.)  It has always been an excitement for me to see a new version of Ubuntu to be released, but this time it’s not the release of a new version of Ubuntu which has excited me.  It’s the announcement that Ubuntu is ready for TV.  Yes, I have never had imagined Ubuntu would be released for TV, but now the cat is out of the bag and I’m loving it.  Check out the video right after the break to see Ubuntu TV in action.

Ubuntu boasts that Ubuntu TV is just TV.  No wires.  No boxes.  Ubuntu suggests Ubuntu TV integrates broadcast, time shift, online box office, personal cloud, apps and disk media experiences.  Why no wires or boxes?  I think as long the TV manufacturers install Ubuntu TV onto their TVs, out of the box experience Ubuntu TV will not require any additional wires or boxes besides the wires that come with the TVs.  Searching for TV programs should be enjoyable on Ubuntu TV since Ubuntu suggests it integrates an intelligent search for Ubuntu TV.  Here I quote Ubuntu’s own words on searching for TV programs with Ubuntu TV:

Cable and satellite TV provide hundreds of channels already. Add online content and the choices increase exponentially. Ubuntu TV helps viewers find entertainment quickly, prioritising their most frequently-watched programmes. Search is ever-present and makes quick work of finding great content. No time to watch now? Single episodes or whole seasons can be recorded and enjoyed at your leisure. And because the TV is a shared device, viewers can create personalised playlists, to keep the kids’ priorities separate from yours. (Source:  http://www.ubuntu.com/tv/experience)

Furthermore, if I’m not mistaken, I think Ubuntu suggests that there will be apps for smartphones and tablets to be used in conjunction with Ubuntu TV so TV users will be able to enjoy side contents on particular shows/programs.  This way, TV users don’t really have to interrupt their TV shows/programs just to peek at additional information on the TV shows/programs that they’re watching. Perhaps, there will be Ubuntu TV remote apps for smartphones and tablets so TV users can control Ubuntu TV with such devices.

It’s unclear how Ubuntu can be installed on TVs.  I surmise TV manufacturers might have to install Ubuntu at the get go before their TVs reach the customers.  According to VentureBeat article Ubuntu TV ‘for human beings’ unveiled at CES, Ubuntu TV is free.  TV manufacturers might see that they can cut down the cost of not having to pay for TV operating system license, and you never know cost saving from TV manufacturers might make smart flatscreen TVs even cheaper for customers.  There is a service fee for each unit which Ubuntu will charge the TV manufacturers.

On Ubuntu’s website, there is a contact form which invites TV manufacturers and content providers to contact Ubuntu in regard to Ubuntu TV.  Perhaps, Ubuntu is inviting TV manufacturers and content providers to test out Ubuntu TV and Ubuntu will provide the support in such matter?  I sure hope many TV manufacturers and content providers will support Ubuntu TV.

Of course, Ubuntu TV is best to be installed on smart TVs, but being true to open source Ubuntu is allowing geeks to download and install Ubuntu TV onto their computers.  Ubuntu’s wiki has the instruction on how to download and install Ubuntu TV onto a computer.  The instruction is here.  Since Ubuntu TV is available for download freely, I think people are going to be using Ubuntu TV in innovative fashions.  One example might be that someone is going to install Ubuntu TV onto USB flash drive so he or she can turn a dumb flatscreen TV into a smart flatscreen TV, but this only works if a dumb flatscreen TV has a USB port.

VirtualBox’s Seamless Mode Saves Users From Switching In And Out Between The Virtual And The Real Machine Computing Environments

Scientists successfully boot one million Linux...VirtualBox‘s Seamless Mode creates an illusion that you are using applications of a virtual machine and applications of a physical machine in the same computing environment.  This way, you don’t really have to switch in and out between the two computing environments (i.e., one is virtual machine and the other is the real machine).  I created a video to show VirtualBox’s Seamless Mode in action and walk you through how to activate VirtualBox’s Seamless Mode.  You can check out the video right after the break.  Enjoy!
