A Linux solution for copying and burning DVDs

The following are my experiences with copying and burning DVDs on Linux. To summarize the experience in a phrase : "It was a walk in the park".

Operating System Ubuntu 8.04

Tools of the trade

• k9copy (for copying DVDs)
• brasero (for burning DVDs)

Installation
Installation in ubuntu for the above packages is as simple as
$ sudo apt-get install k9copy
$ sudo apt-get install brasero

Procedure

• Insert DVD into tray and open k9copy.
• Choose File -> Open. This will load the DVD and show the chapters and titles as shown below. Select all the titles that you wish to copy.

• Select Action -> Copy. You will be prompted for a location where the final iso file will be saved. Make sure that you have disk space atleast 2 times the size of DVD.
• Leave all the options in the below pane as is unless you know what those options mean.
• Once the copy starts you will be able to view the progress in the right-side pane.
• The copy process creates a folder called dvd and an iso image in the location specified earlier.
• You can remove the folder dvd as it is not required during the burning process.
  
• Now to burn the iso image, open brasero and select the option for burning iso images.
  
• Insert and blank DVD and start the burn process.
• Enjoy !
  

In my experience, i have copied 4 DVDs and burnt around 12 DVDs and the whole process took slightly more than half a day. There were absolutely no errors and the original DVD quality was maintained in all the copied DVDs.

Announcing another blog !

Hello dear readers (if any).  I have started another blog (with a better purpose this time). The blog is about Indians and our innovations i.e. Jugaadu Indians and our Jugaads. The inspiration for the blog came to me while reading an article in August 24 issue of The Week. The article is about Indian Ingenuity and our innovations (or colloquially called Jugaads).  The following quote by  Dr. R. Mashelkar puts everything in perspective 

"we should think of innovation as a movement. The I in India has stood for imitation and inhibition for far too long. It is high time it stood for innovation. And the best thing about this movement is that we have the jugaad energy of a billion of us to power it forward. "

The NEWS Equation

Our life today is controlled by media. Be it newspaper, television, radio or the internet, we depend on news for a lot of our day-to-day decisions and sometimes even blindly. This fact is well understood by Media companies, Governments and Businesses alike. Unfortunately, it is also being used actively to mislead the common man.  News today is no more the simple raw information but it undergoes a complex process of editing and mixing before being delivered. Thinking over it for some time, i feel that the Media companies operate a  huge mixer which continuously churns out news according to the following equation 

NEWS = x% Information + y% Hype + z% Personal Biases + w% Political Biases 

Different media companies use different values for x, y, z and w and yield different types of news. A case in point is the recent news about the bootup of Large Hadron Collider (LHC) in CERN. A channel called Aaj Tak in India ran a TV series which would have made a layman believe that the bootup of LHC would destroy the world.  In this case, their percentage of hype was very high and little factual information was presented. Even if they would have done a simple google search for LHC and the myths surrounding LHC, they would have realized that speculations about formation of massive black holes have been long dismissed by emminent Scientists. But the media today is more interested in their own TRP ratings and very little interested in presenting facts. 

When will people learn ?

Airtel (one of India's leading cell phone providers) has recently tied up with Apple to offer the iPhone 3G in Indian market. Everything is good but is the following sort of sales pitch necessary to sell of iPhones?? Airtel is quoted here as saying :

"even the most deadly hackers on the planet won't be able to crack the
codes that support the iPhone's Airtel applications with rival company
SIMs."

My question is : WHY ???. Even if you really have provided tamper-proof security, throwing a n open challenge to the highly skilled and distributed hacker work force on the internet is nothing short of the proverbial "hitting the axe on your own leg". Such stunts may be good to test your products before entering the market but not once the products are already out there. Such stupidity has surely attracted the bees and its just a matter of time before the bees sting.

Return gifts from an internet cafe

Today, i was at an internet cafe for getting a printout as my old printer died its natural death. As usual, the cafe was running Windows XP machines in administrator mode. I never like the look of a windows machine running in administrator mode in a public place and i was quite sure that it was already pwned. Nevertheless, i plugged in my USB drive which contained just the file i wanted to print. After a few seconds, my drive was detected and i could print the file i wanted. All was well and good.

Then i took the drive home and plugged it back into my laptop which fortunately runs Ubuntu. Lo and behold, my drive now had three return gifts from the internet cafe. Doing a quick antivirus scan on the files revealed the following

neoblitz@n30:/tmp$ clamscan /media/PKBACK#\ 001/*
/media/PKBACK# 001/1.jpg: OK
/media/PKBACK# 001/2.jpg: OK
/media/PKBACK# 001/autorun.inf: OK
/media/PKBACK# 001/New Folder .exe: Trojan.Autoit.gen FOUND
/media/PKBACK# 001/regsvr.exe: Trojan.Autoit.gen FOUND

----------- SCAN SUMMARY -----------
Known viruses: 396428
Engine version: 0.92.1
Scanned directories: 0
Scanned files: 6
Infected files: 2
Data scanned: 1.57 MB
Time: 6.231 sec (0 m 6 s)

As you can see, i had 2 trojan binaries and an autorun.inf which pointed to those binaries. For people who didnt realize, this is a worm which uses an unsuspecting user to physically propogate it from machine to machine.

It makes me wonder, how many unsuspecting folks would have got infected by this. Also, the public machine itself is probably a part of some botnet and has all types of exotic malware already installed, sniffing passwords and recording transactions of unsuspecting users. Phew !

So the moral of the story is two-fold,

• Do NOT trust public machines. Avoid using them for doing electronic transactions using your credit card, using your username/password for your email accounts and so on and so forth.
  
• If you run as administator, then very likely you are not the only administrator :)
  

I will publish results of analysis of the binaries in the next post soon.
