What if Cloud Computing Fails

I once wrote about the advantages and disadvantages of cloud computing. And I found this insightful article from PC World, that gives us new idea about what may happen if cloud computing fails. You can read the PC World article here: http://www.pcworld.com/article/164946/google_outage_lesson_dont_get_stuck_in_a_cloud.html Take note of the section that talks about an incident where a cloud server company closes abruptly and they did not even give the customers a chance to recover their data.

This is something that companies would have to consider if they are contemplating of going this route.

Accessing Windows Folders from Wubi Kubuntu

1. Click the K button. 2. Choose File Manager 3. You will be presented with this screen. Kubuntu File Manager 4. Click on Root which is the red folder icon on the left side. 5. You will then get this screen Kubuntu Linux 6. You will notice that is a folder name host. This is your windows folder. You are allowed to copy files between Wubi and Windows.

Benefits of Using Linux

The primary benefit of using Linux is security. You won't have a problem with viruses messing up your computer. In my long experience of using Linux, there was not a time where I had to reformat my computer because of a virus or trojan attack. Or because something messed up with my system registry. It does not mean that viruses won't find their way into your computer. It is just that they won't be able to carry out their malicious intent. They would find themselves stuck in the folder where they first land. And you can simply delete them when you notice them.

So how is this possible?
 
Linux Files and Folders Security Policies There are three kinds of user privelges in Linux.
 
a. Owner - is the person who created a file or folder.

b. Group - a person could belong to a group. The Group setting of a user allows them to have access to files and folders that have been created by another user who belongs to the same group.  

c. Root - This is the admin or superuser. They have access to everything.

There are three kinds of permission settings for each files and folders.

1. read access - Which means you can read but you can't edit them.

2. read/write access - which means they are editable.

3. read/execute - you can read and execute the file but you can't edit them.

4. read/write/execute - you can read, write, and run the file.

The Owner and the superuser can set the privileges available for a file or folder. They have the option to even limit the access of other users that belong in their group. Now if you are not the owner, not a superuser, and not a member of the group, that means you wont even see the file or folder at all. Linux systems files are also editable only by the root user. This is what makes Linux systems very secure. As long as you don't give your access to somebody else, you can be sure that your files and folders will be safe.

Reasons Why I have not yet Updated to Kubuntu 9.04

Actually, I did but I decided to downgrade back to Kubuntu 8.10. My Reasons

1. My Nvidia graphics card was having problem with the latest Kubuntu version. (I think I found the solution to that problem now)

2. Kubuntu 8.10 looks aesthetically better than version 9.04

3. A lot of programs have not yet been updated for this version. Reason #3 is actually my main reason for sticking to Kubuntu Intrepid (8.10). I have decided to wait a few months until developers have updated their software to 9.04. After that I will upgrade.

Wubi: Linux for Windows Part 2

Installing Wubi. There is a bug with the latest Wubi installation. That is why I did not point you directly to the official site in my first post. (You can find the official site here: http://wubi-installer.org/) If you are running Windows XP, the latest installer won't work. This is why we need to get an older Wubi. Try searching google for Wubi 8.10 or you could try downloading a copy at download.cnet.com

When you already have Wubi.exe, here are the things you need to do:
1. Run Wubi.exe
2. It will give you a screen similar to this

3. Choose 15 gig for the hard disk size. Don't worry if the space looks too small. We can adjust it later. And also we will still have access to our Windows folders even if we are in Linux.

4. Choose Kubuntu, my favorite Ubuntu version.

5. Enter a username and the password.

6. Start the installation

7. Restart your PC after the installation is finished.

8. After you start your PC you will see two boot options. The first is your original Windows XP boot. And the other is your newly installed Kubuntu. Choose Kubuntu.

9. You will see the Kubuntu logo, as your newly installed OS starts to load. But is it really installed? Actually, No. It has just started to download the files needed to create Kubuntu.

10. This will take a while so I suggest you do something else (Watch TV, sleep, drink beer, have a hair cut, clean the house, play pratical jokes on somebody - anything to keep you busy for an hour)

11. But after it is finished you will be taken to the Login screen.

12. Enter the user name and the password you provided earlier.

13. After the login screen you will be presented with this. Ain't she a thing of Beauty? :) We are still just using Kubuntu 8.10. There is an option to upgrade to the latest version 9.04 but I won't do that right now. I will tell you about my reasons on my next post.

Wubi: Linux for Windows Part 1

Microsoft has officially ended mainstream support of Windows XP last April 14, 2009 and the extended support will end by April 2014. Windows XP has been the most popular OS of Microsoft. And even though a newer Windows version already came out, people still prefer using Windows XP.

2014 is still a couple of years away but expect newer programs to move away from XP starting next year. So what are your options?

1. Windows 7 – This version is currently available for public testing. It is expected to be better than Windows Vista. Windows Vista has gotten very bad reviews that it is being compared to Windows ME, the worst Windows version ever. Windows 7 will come in six editions. The lower editions will have limited functionalities compared to the higher editions. Of course, the higher editions will cost more. If you are just a home user, would you feel comfortable knowing that you are using a limited OS (Operating System)? Of course not.

2. Linux – This OS has gotten a bad rep of being too geeky. And I do admit that Windows is still easier to use than this one - but not by much recently. It’s developers has taken great strides to make it easier to use. I especially like the Ubuntu distribution packages and my favorite is the KDE flavor which is called Kubuntu.

How do you start shifting to Linux? Try Wubi. It is a software that will allow us to run Linux with Windows XP or Vista without the need to repartition our hard disk.

What is A Computer Virus

Some of you might think its funny but I know a few people who think that computer viruses are actual virus just like common colds. Indeed it is the casual computer users who are the most vulnerable victim of computer viruses.

So if you are a casual computer user and not really a technical person, how can you better protect yourself?

The best way to protect yourself, aside from downloading anti-virus software, is to know what you are up against. Unlike real viruses that spread through human contact or proximity, computer viruses spread when a computer user runs an infected program. That means, they are practically harmless as long as you don’t run them.

Here are some precautions that could help you better protect yourself:

1. Don’t run and Scan any program you are unfamiliar with

2. Scan any program you download from the internet

3. Scan any storage device that is shared to you like USB Flash drives, hard disk, and floppy disks (if you still have them but I don’t if ever anyone still uses them).

4. If you are in a network, don't share folders with full read and write access. If you need to share some files, make sure that the folder they are in has only read access.
