Portable Ubuntu in Windows

April 30th, 2009


This is a short sequel for Using Ubuntu in Windows XP as there is a way that you can try Ubuntu without installing Ubuntu or even having virtualization software like VirtualBox.

Portable Ubuntu for Windows is a software that runs Ubuntu on Windows, without requiring any installation.
You can have Ubuntu with you in a thumbdrive and run it on multiple computers with your files in the thumbdrive too.

Download it here.

It is an executable zipped file which will need extraction. Extract it to your selected folder or thumbdrive, and just run the run_portable_ubuntu.bat file to load Ubuntu.

A console will load and show you the progress of running Ubuntu. It is kind of a system log if you compared it to running Ubuntu on a system in virtualization mode.

This version of Ubuntu loads as an application toolbar on the top of your Windows Desktop.

It actually runs on XMing (XServer for Windows).

The TopEdge Panel is just like the actual application bar but the available applications are less. You can still select Add/Remove programs.

I encountered some problems downloading the OpenOffice package though. :-(

All the password for Portable Ubuntu adminstrative tasks, especially software installation is 123456.


You can run Terminal console:

Firefox is available too:

The verdict:
Portable Ubuntu for Windows is useful to Windows users interested to test or try out Ubuntu’s application.
Although it is not a full-blown OS, but the portability of it is the main objective of this software, so you can bring this entire portable version of OS in your thumbdrive and files together with it.
However, the creator or creators of this software is not officially from Ubuntu and you might need to check out its forum and contact the creator from this site.

Using Ubuntu on VirtualBox in Windows XP

April 29th, 2009


What is Ubuntu?
Ubuntu is a community developed, Linux-based operating system that is perfect for laptops, desktops and servers.

What is VirtualBox?
VirtualBox is a software by Sun Microsystems that allows you to use multiple operating systems (guests) on another operating system (host).
VirtualBox runs on Windows, Linux, Macintosh and OpenSolaris hosts and supports a large number of guest operating systems including but not limited to Windows (NT 4.0, 2000, XP, Server 2003, Vista), DOS/Windows 3.x, Linux (2.4 and 2.6), Solaris and OpenSolaris, and OpenBSD.

Why Ubuntu on VirtualBox in Windows XP?
I have always wanted to try out Ubuntu as it is a popular operating system now, having tagline as “Linux for Human Beings”. Linux is not as “scary” for non-techie nowadays and having OS like Ubuntu with such taglines definitely helps a lot.

I would like to try out Ubuntu, but am not ready to install Ubuntu as the main or host operating system in my computer.

I tried VMWare before and would like to try out Sun’s VirtualBox which I found there are a number of positive comments about it.

And the best reason : Ubuntu is free, Windows is costly. :-)

So using Ubuntu on VirtualBox in my Windows XP system will enable me (or you), to try out Ubuntu and maybe prepare oneself to use it in the future?

Anyway, here’s the experience:
* Click on the images to view in original size.

Download VirtualBox and select the Operating System (host) you’re using.

Download the Ubuntu operating system. It is a CD image file (iso). You can choose to keep it in your disk or burn it into a CD for portability.

Installation of the VirtualBox is pretty straightforward. Just run the installer and follow through the steps:






There are a few alerts such as it will disconnect your network connection and also that the software has not passed Windows testing (as usual). Just continue with it until the end.

Running it
In my opinion, VirtualBox has interface similar to VMWare, so VMWare users should be familiar with this software.

VirtualBox does not come with any guests operating system, so what we need to do is to use the Ubuntu CD image downloaded and get VirtualBox to run it.

Let’s start by creating a new Virtual Machine, by clicking on the New button:


Select Ubuntu as the guest operating system:


Allocate at least the minimum memory requirement specified.


Create a harddisk for Ubuntu. Select “Create New Hard Disk” if you do not have an existing one. The hard disk here actually meant it’s a file which will be used as a logical disk (not really hard disk) for Ubuntu.


Now you have Ubuntu as an operating system.


Power up Ubuntu!
Well it doesn’t just work like that.
We have to get it to load the Ubuntu CD image before it is able to run.


So we will need to select “Mount CD/DVD ROM image” and then choose the file we have downloaded previously.


Ubuntu will load and prompt you with a few options.
Since we’re not installing Ubuntu, let’s just try Ubuntu without any change to your computer. ;-)


This is the desktop of Ubuntu.


The File Browser, very much like your usual Windows Explorer.


It has Firefox 3 pre-installed.


There’s also this instant messaging software, Pidgin that is actually instant messengers with the ‘s’. You can add whatever IM accounts you have. From my test, the speed of the login and messaging is very good. :-)


The Applications under Accessories:


The Applications under Games:


The Applications under Graphics:


The Applications under Internet:


The Applications under Office or your office applications:


The Applications under Sound and Video:


You can also check out what’s pre-loaded in Ubuntu and select additional software from the Add/Remove application menu. From the list of applications available, you are definitely spoilt for choice!


OpenOffice is pre-installed. You can save it in Windows Word format, or OpenOffice format. Nowadays, you do not have to worry about file format too much. Hey, if you do not like OpenOffice, there’s always Google Docs. :-D


I changed the desktop background with one selected from HongKiat’s 60 Beautiful Ubuntu Desktop Wallpapers


The verdict:
This is a great way to try Ubuntu without much effort or worry about it messing your computer.
The only drawback is when I tried running multiple applications at once, it hangs. This could probably due to the small memory allocation I used.
I’m not able to run it full-screen. Although when I selected fullscreen, the Ubuntu desktop is still 800×600 with black background filling the sides. Maybe I’m doing this wrong, but I’m not able to find the workaround for this, yet.
I just might be using Ubuntu if I’m getting a new computer system or laptop. :-)

Green indicator for Extended Validation SSL Certificates

March 4th, 2009

If you’re using Firefox 3 or IE 7, chances are you might notice that the fav icon (Firefox) and url bar (IE) sometimes turn green.

It is one of the security features from the new browsers, to indicate that the communication between you and those websites are highly secured.

Mozilla has explained it in the Firefox 3 Release notes:

More Secure

* One-click site info: Click the site favicon in the location bar to see who owns the site and to check if your connection is protected from eavesdropping. Identity verification is prominently displayed and easier to understand. When a site uses Extended Validation (EV) SSL certificates, the site favicon button will turn green and show the name of the company you’re connected to.

If you’re using Firefox3, try these sites and see the differences:




Those having EV certs has owner identity vetted by the CA authorities, while typical SSL certs only performs a validation against the domain name. Please do not get confused that typical certs are not secured. All SSL secured sites encrypts data, but those with EV certs has higher trust as their identify has been “verified”.

So in case you’re wondering how you could change your fav icon for Firefox to be so cool, you’d need to buy an Extended Validation SSL for that to happen.

Extended Validation Certificates (EV) are a special type of X.509 certificate which requires more extensive investigation of the requesting entity by the Certificate Authority before being issued. Source : Wikipedia
